How to Choose Diesel Generators for the Manufacturing Industry?

In today's competitive manufacturing industry, an efficient and stable power supply is essential to ensure the continuous operation of production lines. As a reliable backup and main power supply, diesel generators are widely used in various production scenarios. However, there are a wide variety of diesel generator sets with different performance available on the market. How do manufacturing enterprises choose the generators that best suit their own production line needs? Below are some key factors that should be considered.

Before choosing a diesel generator, manufacturing enterprises need to analyze the actual demand of the production lines in detail. It’s necessary to understand the electrical load characteristics of the production line, the type and amount of electrical equipment, the operation mode of the production line, and future expansion plans and so on.

Electrical load characteristics: Equipment on the production line usually includes continuous operation equipment and intermittent operation equipment. Equipment such as lighting, ventilation and monitoring systems that need to operate continuously require a stable power supply. Equipment such as machine tools, welders and cranes are used intermittently according to the production takt. Thus, when selecting a diesel generator, you need to consider if the generator can meet the power demands of the equipment, especially during peak load hours.

Electrical equipment types and quantity: List all equipment such as motors, heaters and cooling equipment that need to be powered by diesel generators as well as their rated power. Please note that the actual operating power of the equipment is often lower than the rated power. It is also necessary to consider the power factor (PF) for conversion.

Production line operating modes: Different production lines have different operating modes, such as three shifts, two shifts or single shift. This affects the use time and load curve of the diesel generator sets, which in turn affects the choice of their power capacities and quantities.

Future expansion plan: When investing in diesel generators, keep in mind that their power capacities not only meet the current needs, but also can cope with possible future increases in electrical equipment or production line expansion. Thus, consider a 20-30% margin above the required power for future power requirements.

Factors need to consider when selecting diesel generators for manufacturing industry

Based on the demand analysis of the production lines, manufacturing enterprises should consider the following key factors when selecting diesel generator sets:

Generator power capacity: It’s necessary to understand the prime generators and standby generators. A prime generator set is any standard genset that is used as the primary power source for the equipment it is powering. It is intended for continuous operation, which is usually best utilized in situations where you are away from a utility source of power such as the mains power from a house or other building. Standby Power (emergency power) is to be used when the main source of power fails. It is the maximum output power that the unit can achieve in a short period of time, such as 30 minutes, which is used to deal with sudden high load. Thus, the prime power should be considered to ensure that the generator can meet the daily electricity demand of the production line.

Peak power requirements: Pay special attention to whether the production line has an instantaneous high-power demand, such as starting a large motor. This may require a diesel generator with a higher standby power or reducing the start shock by means such as soft starting.

Fuel Efficiency and emission standards: With the improvement of environmental protection requirements, choosing diesel generators with high fuel efficiency and low emissions can not only reduce operating costs, but also respond to the call for green production. This helps enterprises improve their social image and reduce environmental pollution.

Noise level: Noise level is an important consideration for generators that need to be installed near production lines or in densely populated areas. Choosing a diesel generator with a noise reduction design can reduce the impact on the surrounding environment, improve the working environment of employees and the quality of life of surrounding residents.

Reliability and durability: The reliability and durability of diesel generator sets are directly related to the continuous operation of the production lines and the production efficiency of the enterprises. Therefore, priority should be given to generator sets with well-known brands, such as Cummins and Perkins. These brands usually have an excellent quality assurance system and after-sales service network, which can provide timely maintenance services when the equipment fails.

Automation and intelligence: With the development of intelligent technology, more and more diesel generator sets are equipped with automatic control systems and remote monitoring functions. These functions can realize remote monitoring, fault diagnosis and automatic start and stop of the unit, improve operation and maintenance efficiency and reduce labor costs.

Generator maintenance and service: Consider the easy maintenance feature and after-sales service quality of the generator. Make sure the diesel generator has a rapid response in emergency situations and ensure uninterrupted power supply. Moreover, choose models with easy access to spare parts to reduce downtime caused by spare parts shortages.

Choosing the right diesel generator set not only ensures the continuous operation of the production line, but also saves costs and improves production efficiency.

The Function of Thermostat in Diesel Engines and Consequences of Removal

Currently, most diesel engines use wax - type thermostats with stable working performance. When the temperature of the cooling water is lower than 83°C, the thermostat valve closes. The cooling water can only circulate in a small loop within the diesel engine without passing through the water tank for a large - scale circulation. This accelerates the rise of the cooling water temperature, shortens the warm - up time, and reduces the running time of the diesel engine at low temperatures.

When the coolant temperature reaches the opening temperature of the thermostat valve, 83°C, as the temperature of the diesel engine gradually rises, the thermostat valve gradually opens. More and more coolant participates in the large - scale circulation for cooling, and the heat - dissipation capacity increases accordingly.

Once the temperature reaches or exceeds the full - opening temperature of the main valve, 95°C, the main valve fully opens, and the auxiliary valve completely closes the small - circulation passage. At this time, the heat - dissipation capacity is maximized, ensuring that the diesel engine operates within the optimal temperature range.

When it is found that the water temperature of the diesel engine is too high, instead of carefully checking whether there are reasons in the diesel engine cooling system, such as a damaged thermostat or excessive scale in the water tank, some people simply think that the thermostat hinders the circulation of the cooling water based on their perception.

What will happen if the thermostat is removed due to high water temperature?

Excessive fuel consumption

After removing the thermostat, the large - scale circulation dominates. The engine dissipates more heat, resulting in more wasted fuel. When the engine runs below the normal working temperature for a long time, the fuel combustion is incomplete, which further exacerbates fuel consumption.

Increased oil consumption

When the engine runs below the normal working temperature for a long time, the engine combustion is incomplete. More carbon black enters the engine oil, making the oil more viscous and increasing the amount of sludge.

Meanwhile, the water vapor generated by combustion easily condenses with acidic gases. The resulting weak acid neutralizes the engine oil, increasing oil consumption. In addition, the diesel entering the cylinder is poorly atomized. The non - atomized diesel washes away the oil on the cylinder wall, diluting the oil and increasing the wear of the cylinder liner and piston rings.

Shortened engine life

Due to the low temperature, the engine oil has high viscosity and cannot lubricate the friction parts of the diesel engine in time. This increases the wear of the diesel engine components and reduces the engine power. The water vapor generated by combustion easily condenses with acidic gases, aggravating the corrosion of the engine body and shortening the engine life.

Removing the thermostat brings nothing but harm!

When it is found that the water temperature of the diesel engine is too high, if it is confirmed that the coolant level is normal and the water in the water tank is flowing, indicating that the water pump is working properly, it is necessary to check whether the thermostat has failed.

The method is as follows: Remove the thermostat from the machine and put it in hot water at 82 - 85°C. If the thermostat cannot open more than 1mm, it indicates that the thermostat has failed. If it is put in water at 95 - 100°C and taken out after a few minutes, and the main valve of the thermostat is fully open, it indicates that the thermostat is working normally; otherwise, it indicates that the thermostat has failed.

Once it is determined that the thermostat has failed, a new one should be replaced in time. Otherwise, the diesel engine will run at a low (or high) temperature for a long time, causing abnormal wear or overheating of the diesel engine and leading to serious accidents. The new thermostat should be tested for quality before being installed. Never operate the diesel engine without a thermostat, as this will cause the diesel engine to run at a low temperature for a long time.

Whether the equipment are the cameras or the lighting equipment on the filming site, or the post-production equipment, they all need stable and reliable power support. Unstable or interrupted power can result in interrupted filming, damage to equipment, and even affecting the progress and quality of the entire project. Therefore, investing in high-efficiency diesel generator sets has become an important measure for the film and television industry to ensure the reliable power supply for shooting.

Determine the power requirements

Before choosing a diesel generator set for the film and television industry, it’s necessary to figure out the total power needs, including the electricity demand of the shooting location, the total power of the electrical equipment and the time of using electricity. Also consider whether there are special needs for the generators such as low noise level and low-temperature start function.

A filming site usually involves a large number of electronic equipment power needs, such as cameras, lighting equipment and recording equipment. These devices need stable power supply and sufficient power to work smoothly. Calculate the total power of all electrical equipment and ensure that the power capacity of the diesel generator can meet the needs. Meanwhile, it is also necessary to take into account the possible increase in electricity demand in the future, and add a certain power margin to the total power.

In some cases, the film and television industry may also need to think about some special requirements for diesel generator sets, such as low noise and low temperature start-up. For example, in a quiet shooting environment, it is particularly important to choose a silent diesel generator.

Thus, select a right size diesel generator. If the generator is too small, it can’t meet the power needs. If the generator is too large, it will cause energy waste and a cost increase. Different types of electrical equipment have different load characteristics. Consider the impact of load characteristics on the devices when buying a diesel generator.

In order to cope with the possible increase in electricity demand in the future, consider a 20-30% margin above the required power for future power requirements.

How to Choose Diesel Generators that Need to Work in Humid Environment?

In high humidity environments, diesel generators’ performance, reliability and lifespan can be significantly affected. Humidity will not only cause electrical components to be damp, but also may accelerate the corrosion of metal components, affecting the overall performance of the unit. Therefore, it’s important to choose the right diesel generators that need to operate in high humid climates.

The bad influence of humid environments on diesel generators

Reduced insulation performance: In a humid environment, the electrical components inside a diesel generator are susceptible to moisture, resulting in reduced insulation resistance and bad electrical performance. This may not only cause short circuit and electric leakage, but also pose a serious threat to the stable operation of the unit.

Corrosion of metal parts: A high humidity environment will accelerate the corrosion of metal components, such as terminals, bolts and nuts, in the generator set. The corrosion not only reduces the mechanical strength of components, but can also cause problems such as poor contact and short circuits.

Acceleration of aging of electrical components: The high humidity environment will accelerate the aging process of the electrical components, such as capacitors, resistors and inductors,  inside the diesel generators. Aging of these components may lead to reduced generator performance and even failure.

Reduced heat dispersion performance: In a high humidity environment, the heat dissipation performance of the generator set may be affected to some extent. Because the moisture in the air will adhere to the radiator, reducing the heat dissipation efficiency, resulting in an increase in the temperature of the unit, which will affect its stable operation.

How to choose diesel generator sets used in high humidity environments?

Choose a diesel generator with excellent moisture resistance

If you are looking for a diesel generator that you plan to use it in a high humidity environment, consider choosing the one with excellent moisture resistance. These units are usually made of special materials and have a manufacturing technique that can effectively protect the internal electrical components from moisture and corrosion. You can choose diesel generators whose electrical components are with moisture-resistant coatings, as well as the terminals and fasteners made of corrosion-resistant materials such as stainless steel.

Consider the genset’s insulation performance

When selecting a generator set, you should pay special attention to its insulation performance. In a high humidity environment, the insulation resistance of the diesel generator should be kept at a high level to ensure the normal operation of the electrical components. Thus, you should consider the performance of the generator’s insulation material and whether it has been specially treated to improve moisture resistance.

Choose a generator with good heat dissipation performance

In a humid environment, the heat dissipation performance of the diesel generator set is particularly important. Therefore, select a diesel generator with good heat dissipation performance to ensure that it can still maintain good operating status in a high temperature and high humidity environment. This type of generators usually have efficient radiators, as well as optimized heat dissipation channels to improve heat dissipation efficiency.

Consider the IP levels of diesel generator

The IP (Ingress Protection) rating of a diesel generator set, which is commonly used to define the level of protection the equipment offers against solid objects and liquids, can vary depending on the specific model and manufacturer. Diesel generators with higher levels of protection can be able to resist the intrusion of moisture and corrosive substances more effectively. Thus, you need to understand the protection levels of the generator and choose the right one according to the actual environmental requirements.

Choose diesel generators with intelligent monitoring and alarm functions

In high humidity environments, diesel generators may face more risk of failure. Therefore, it is particularly important to select a generator set with intelligent monitoring and alarm functions. This type of generators like Dingbo diesel generators can monitor the operating status and parameters in real time. Once any abnormal situation is found, it can timely send alarms to you and take appropriate protective measures to ensure the safe and stable operation of the unit.

To sum up, choosing the right diesel generator set in the high humidity environment is crucial to ensure the stability and reliability of the power supply. A generator set with excellent moisture resistance, good insulation performance, good heat dissipation performance and intelligent monitoring and alarm functions can effectively reduce the impact of high humidity environment on the generator set.

Role and Function of Governor in Cummins Diesel Generator

The rated speed of our Cummins diesel generator is 1500 rpm. For the generator set to maintain a stable speed, a governor is required. The governor can automatically adjust the fuel supply according to the load changes of the diesel generator set. It can be said to be an essential factor for the stability of the Yuchai diesel generator.

Now, let's specifically talk about the two main uses of the governor:

When the speed of the Cummins diesel generator deviates from the set value, the governor can promptly make corresponding reaction actions. It also has the function of a restoring force to return the governor to its initial state. You should know that the spring in the centrifugal governor of our diesel engine parts is the part that generates the restoring force. Such a governor is also called a statically stable governor. However, a statically stable governor may also experience dynamic instability during the adjustment process. When the adjustment action is excessive and reverse adjustment occurs, in fact, the adjustment action will form an oscillation process. A governor that can quickly reduce the oscillation is called a dynamically stable governor. Otherwise, it is a dynamically unstable governor, and the latter cannot fully guarantee the normal operation of the diesel generator set.

Adding damping to the diesel generator set's adjustment system is also a commonly used method to improve dynamic stability. The damping in the adjustment system, such as the friction in the kinematic pair, makes the governor have a certain degree of insensitivity. In other words, when the speed of the controlled shaft slightly deviates from the set value, the governor will not produce a corresponding action. The insensitivity of a mechanical governor is generally about 1% of its set value. On the contrary, a governor with excessively high sensitivity will also produce unnecessary adjustment actions due to the periodic speed fluctuations during the normal operation of the diesel generator.

Consequences of Overloading Diesel Generator Sets

It is extremely unsafe for a diesel generator set to operate under overload, and overloading is strictly prohibited. So, what are the consequences of overloading a diesel generator set? Dingbo Power, a generator manufacturer, believes that overloading a diesel generator not only leads to high fuel consumption but also more easily causes generator set malfunctions that require repair.

In general, when the load of a diesel generator set is 80% of the rated load, the fuel consumption is normally at its minimum. If the load increases, the fuel consumption will rise. The fuel consumption of a diesel generator set is directly proportional to the load. However, if the load is lower than 20%, it will have an impact on the diesel generator set. Not only will the fuel consumption of the unit increase significantly, but it may even damage the generator set.

Therefore, to reduce the fuel consumption of a diesel generator, the unit can be operated at around 80% of the rated load. Running at a low load for a long time will actually increase fuel consumption and may even damage the unit. Remember, overloading a diesel generator set not only results in high fuel consumption but also more easily causes malfunctions that require repair.

Overloading a diesel generator set can easily lead to the following malfunctions:

1.It is easy to damage the engine cylinder gasket.

2.It can easily increase the thermal and mechanical loads on the cylinder liner.

3.The turbocharger of the ultra - silent generator set will turn red. After being exposed to high temperatures for a long time, the turbocharger will be damaged.

4.Malfunctions such as cylinder scoring and bearing burnout are also likely to occur.

5.The generator will have difficulty dissipating heat due to overloading, and the coils may be punctured and burned out.

After a diesel generator set operates under overload, oil may overflow from the fuel tank opening, and the high - pressure oil pipe may wear and leak. When a diesel generator set is delivered and accepted, it is an essential item for the generator manufacturer to train users on the normal operating procedures of the diesel generator set. Users must study these procedures carefully and put them into practice. Many serious malfunctions often occur due to users' negligence and non - standard operations, which we must take as a warning.

Dingbo Power has advanced testing equipment, modern production technology, professional manufacturing technology, perfect quality management system, and strong technical research and development capabilities. It can provide 3KW～2500KW various specifications of ordinary, automatic, four protection, automatic switching, low noise and mobile generator sets, high quality and low energy consumption to meet the diverse power needs of customers, and can also meet users with different voltages and different frequencies. It is required to create a parallel power supply system for multiple units. If you are interested in our product or any question on generator, welcome to send email to [email protected].

Factors such as low temperatures, increased humidity, and snow and ice can have an adverse effect on diesel generators, resulting in reduced generator performance or failure. To ensure the stable operation of your diesel generator in winter, today Dingbo Power shares several tips on generator maintenance in winter.

Comprehensive generator inspections

First of all, check the overall status, operating records, and historical fault data of your diesel generator. In this way, you can know the current condition of the equipment and determine the parts that need to be maintained and potential problems that exist.

Perform a comprehensive inspection of the key components of your diesel generator set, such as the engine, alternator, fuel system, cooling system, and electrical system. Check for the wear, connections, tightness of the components and check if there is unusual noise or vibration. Make a detailed preventive generator maintenance plan based on the inspections.

Maintain the generator fuel system

In winter, the temperature is low and the diesel fuel is easy to condense and clog. Therefore, replace the fuel filters regularly to prevent impurities and moisture from entering the fuel system and affecting the normal operation of the generator.

Take measures to keep the fuel tank warm to reduce the condensation and deposition of fuel at low temperatures. You can wrap the fuel storage tank with insulation materials, or install a heating device to keep the diesel fuel’s temperature within the appropriate range. Meanwhile, check the quality of diesel fuel regularly to ensure that it meets the requirements of the generator. If the fuel quality is poor,replace it in time to avoid damage to the equipment.

Maintain the cooling system regularly

Use proper coolant in winter to prevent it from freezing at low temperatures. Before the onset of winter, replace the coolant with one that is suitable for low temperature environment, and check the level and quality of the coolant.

Clean the cooling system regularly to remove scale deposit, rust and impurities to keep the system unimpeded. When cleaning, use professional cleaning agents and tools to avoid damage to the system. Check the operation of the cooling fan to ensure that it can dissipate heat normally. If the fan blade is deformed, loose, or damaged, replace or repair it in time.

Maintain the electrical system

Batteries are vital for the diesel generator set’ start-up and operation. In winter, battery performance is easily affected due to low temperatures. Therefore, you need to check the voltage, internal resistance and electrolyte density of the batteries regularly to ensure that the they can supply power normally. Also keep the batteries clean and dry to avoid electrolyte leakage or corrosion.

Check the wiring and connections of the electrical system and ensure that there is no loosening, corrosion, or short circuit. For aging wiring and connectors, replace them in time to avoid electrical failures. Electrical system should also be regularly tested for insulation performance to ensure that the insulation performance between the components is good. If the insulation performance is found to be reduced, take measures in time to deal with it to avoid electrical accidents.

Keep the diesel generator warm

Take measures to keep the generator warm to reduce the heat loss of the equipment at low temperatures. You can use heat insulating materials to wrap the key parts such as the engine and radiator of the generator. Or install a heating device and keep the temperature of the equipment within the appropriate range.

Anti-freezing treatment should be carried out on the parts that are easy to freeze, such as fuel pipelines and cooling pipelines. You can use insulation materials to wrap the pipes, or install heating bands, heaters and other equipment to keep the temperature of the pipes above freezing.

It is necessary to formulate detailed emergency measures and plans to cope with possible failures and abnormal conditions of generator in winter. Emergency measures should include troubleshooting procedures, backup power supply enabling plans and emergency shutdown procedures to ensure rapid response and handling in emergency situations of diesel generator.

In addition to the tips mentioned above, the daily maintenance of diesel generators in winter is also crucial. Regularly check the operating status of the equipment, clean the surface of the generator, check whether fasteners and connectors are loose, etc.

The maintenance of diesel generator set in winter is of great significance for the stable operation and extended lifespan of the equipment. With the tips shared in this article, we hope you can effectively reduce the risk of generator failure during the winter and ensure the stability and reliability of the power supply.

Choosing between Single Phase and Three Phase Diesel Generatorsiesel Generators

Generators are more commonly used in our daily lives compared to other machinery. For example, many people choose to install a generator for water pumping during home decoration to deal with short - term water supply shortages. When buying a generator, we often hear about single - phase diesel generators and three - phase diesel generators. However, many of us don't understand the terms "three - phase" and "single - phase". I often hear our salespeople say that when asking customers whether they want a "three - phase" or "single - phase" generator, customers usually choose the three - phase one, thinking that it must be more useful than the single - phase one. But is that really the case? In fact, the three - phase generator isn't suitable for all places.

Single - phase power has a voltage of 220 volts, which is the voltage between the phase line and the neutral line. Three - phase power has an inter - phase voltage of 380V among phases a, b, and c, and is used for 380V three - phase electrical motors or equipment. Three - phase power is mainly used as the power source for motors, that is, loads that need to rotate. Since the phase difference between the three phases of three - phase power is 120 degrees, the rotor won't get stuck. Three - phase power is designed to create this "angle"; otherwise, there'd be no need for such a complex power system.

Secondly, there are differences between three - phase diesel generators and single - phase diesel generators. Three - phase diesel generators are used in industrial production, with a voltage of 380V; single - phase diesel generators are used for ordinary residential use, with a voltage of 220V.

Three - phase power has four wires, including three 220V live wires and one neutral wire. Combining any live wire with the neutral wire gives us the common household electricity, which is 220V. However, for the balance of three - phase power, it's recommended to connect corresponding loads if possible. A diesel generator that can generate electromotive forces with equal amplitudes, equal frequencies, and a 120° phase difference is called a three - phase diesel generator.

Three - phase power can provide a more reasonable power source. When used as the power source for a motor, there's no need for anything else; just directly connect the three - phase power to the motor, and it can run. If it's a single - phase motor, a complex device needs to be added to ensure its operation.

There are differences. Three - phase power has a voltage of 380 volts, while single - phase power has a voltage of 220 volts. So - called three - phase power refers to three live wires, and the voltage between adjacent live wires is 380V, without a neutral wire. Therefore, three - phase power can only be used when the three - phase loads are the same (for example, a three - phase motor). At this time, since the vector sum of the currents of the three - phase power is 0 (the three - phase powers are at 120 - degree angles to each other, so their sum is 0), there's no need for a neutral wire (equivalent to the neutral line).

So, when making a choice, we need to understand our own needs and make a selection based on them. This requires us to learn more about the differences between products so that we can better choose the products that meet our needs.

As a professional diesel generator manufacturer, we always insist on using first-class talents to build a first-class enterprise, create first-class products, create first-class services, and strive to build a first-class domestic enterprise.

How to Choose An Industrial Backup Diesel Generator?

In the field of modern industry, the stability and reliability of power supply plays an important role in maintaining business operations. Power interruption may bring huge economic losses and security risks to industries such as manufacturing, construction industry and service industry. Therefore, buying an industrial backup diesel generator with excellent performance is crucial to ensure the continuity and stability of business operations. In this article, Dingbo Power will share a few key factors to consider when choosing to purchase an industrial diesel generator.

Power requirements

First of all, when choosing a diesel generator for your business, you need to assess your power requirements. Figure out the total load that your generator needs to power. Consider the frequency and voltage requirements of your facilities, the daily and peak power consumption of your enterprise and the types of loads your generators need to support. Take into account both continuous running watts and peak starting watts. Consider potential future power needs and it’s wise to add 20-30% to your total power. Choose a diesel generator that is capable of providing enough power to meet the requirements of your equipment.

Portability and Stationary

Different applications require different types of diesel generators. Portable diesel generators are ideal for low energy demand situations or when a high level of mobility is required. If your company works in different locations and needs low or only temporary power, portable units suit you best. Portable generators often have wheels and can be moved to different places easily.

Unlike portable generators, stationary generators are designed for permanent installation and they cannot be moved. Station diesel generators are suitable for addressing very high power requirements, such as those of an enterprise, for very long periods of time. This type of generators come in wide range of sizes for a variety of industrial applications.

Fuel efficiency

Efficiency is a crucial consideration for diesel generators. When buying an industrial diesel generator, make sure that the one you choose is efficient. A diesel generator with high fuel efficiency can lead to significant cost savings in the long run because it can provide reliable power while consuming less fuel. Efficient generators also produce fewer emissions and contribute to reduced environmental impact.

Noise level

When choosing a diesel generator for your industrial application, the generator noise level should also be considered. Diesel generators produce noise when in use and their noise ratings are measured in decibels (dBA). Large industrial diesel generators can produce loud noises when operating. If your generators need to be installed near residential areas or quiet workspaces, consider choosing silent type diesel generators with soundproof enclosures and noise reduction materials.

Transfer switch

Transfer Switches transfer the load from the mains supply to the generator supply and back again. A transfer switch is usually installed near your circuit panel. By installing a transfer switch, you can safely switch between the sources manually or automatically depending on the installation and features of the transfer switch. An Automatic Transfer Switch (ATS)  has the ability to switch the diesel generator on when there is a loss of power, and once your regular power supply comes back, it turns off.

At Dingbo Power, we provide various types of diesel generators with power capacity ranging from 25kva to 3000kva.We can provide you with the best generator for your business. Feel free to contact us with any questions, concerns, or inquiries to learn more about the products & services we provide.

Understanding Emergency Shutdown Device of Diesel Generator Sets

When using diesel generator sets for a long time, it is essential to know the functions of the emergency shutdown device and the alarm switch.

(1) Emergency Shutdown Device of Diesel Generator Sets

The emergency shutdown device of Shangchai diesel generator sets can be operated electrically, mechanically, or hydraulically. Users should be familiar with the shutdown mode and location of the shutdown device installed on their diesel generator engines, the conditions for activating various shutdown devices, and the reset steps required before restarting.

The working principles of all electric shutdown devices are similar. When a certain critical operating condition occurs, a switch is activated to stop the engine. The shutdown device needs to be reset before the engine can be restarted.

The shutdown device should be inspected by the company's personnel every 1000 working hours. The engine unit staff can test the hydraulic - mechanical shutdown device every 500 working hours. Generally, the emergency shutdown device should not be used during normal shutdowns. The cause of the sudden shutdown must be identified, and necessary repairs should be carried out.

(2) Alarm Switch of Diesel Generator Sets

The set temperature, pressure, or liquid level critical values when the alarm of Shangchai diesel generator sets is activated are more stringent than those for emergency shutdown, that is, the alarm is triggered in advance. The purpose of the alarm is to warn the operator of an impending unsafe situation, and corrective measures must be taken to prevent engine damage.

After the alarm is triggered, necessary corrective measures should be taken before the situation turns into an emergency. Each alarm switch is connected by wires to an indicator light, a bell, or a speaker. The alarm continues until the fault is eliminated, and then the indicator light goes out, and the bell or speaker stops ringing. To prevent the alarm from sounding during the repair process, a two - way switch and a red indicator light can be installed. When the switch is toggled to cut off the alarm, the red light lights up. If the switch remains in the "OFF" position after the repair, the red light continues to shine, indicating that the engine is not in a protected state.

Tips for Purchasing Cummins Diesel Generator Sets

We often learn some tricks to avoid being deceived. When buying things like Cummins diesel generator sets, we also need to learn some relevant common sense. Now, let's follow the editor of Guangxi Dingbo Power to find out!

1.First of all, you need to determine the power of the generator set you want to choose. The power of the diesel generator should be more than 30% larger than the selected power, and a 10% reserve for the motor power should be left. If there is a high - power single - motor (non - variable frequency start), the power of the diesel generator should be three times larger than that of the motor to start the motor smoothly.

2.You should make a choice on the brand and price of the diesel generator and the generator. For the diesel generator, you should consider configurations with mature technology, low fuel consumption rate, low maintenance cost, and high reliability. For the generator, generally, the products from regular domestic manufacturers that mass - produce brushless motors can meet the requirements.

3.The choice of the control unit of the generator set should be based on the place of use. For example, units where operators are not used to using LCD screens can choose manual screens, while places with high automation requirements can choose full - LCD screens.

4.When purchasing, you should also guard against unscrupulous manufacturers from falsifying the power of the generator and the diesel generator. You should also ask whether the cooling water tank and the generator are made of pure copper in the configuration of the generator set.

There are several factors to consider when purchasing a diesel generator set:

(1) If there is a gap between the operating environmental conditions and the rated environmental conditions of the diesel generator set, the temperature, humidity, and altitude should be specified at the time of signing the contract to ensure a suitable model and supporting equipment are provided.

(2) The cooling method to be adopted during use should be specified, especially for large - capacity units.

(3) When placing an order, in addition to specifying the unit model, the specific model of the equipment should also be indicated.

(4) The voltage regulation rates of diesel generator sets are 1%, 2%, and 2.5% of the rated voltage respectively. You should specify which one to choose.

(5) Under normal supply conditions, a certain amount of vulnerable parts will be provided. If you need more, you should also state it.

Eight Key Checks in Diesel Engine Repair

1."Three Leaks" Prevention

To prevent and resolve oil, water, and air leaks, follow the "Five-Character Principle": Strictness, Cleanliness, Smearing, Grinding, Tightening.

Strictness: Adhere to operating procedures during disassembly/assembly. For example, tighten bolts sequentially and incrementally to avoid deformation.

2.Cylinder Pressure Check

Ensure adequate compression by verifying:

Piston-cylinder clearance, piston ring end/side gaps

Valve-seat and injector tip tightness

Proper cylinder head gasket thickness

3.Combustion Chamber Volume Check

Avoid altered compression ratios caused by:

Reversed piston installation

Incorrect gasket thickness

Worn/bent crankshaft-linkage components

Misaligned swirl chamber inserts

Excessive valve recession

4.Timing Check

Fuel Injection Timing: Adjust via shims between the injection pump and gear cover (0.1mm shim = 6.3mm flywheel arc for S195/X195 models).

Valve Timing: Correct timing gear alignment errors first, then adjust valve clearance (0.1mm clearance = 3° crankshaft rotation = 11.1mm flywheel arc). Cold clearance must be ≥0.2mm to prevent post-heating leakage.

5."Three Filters" Check

Air Filter: Prevent dust-induced wear of pistons, cylinders, and valves.

Fuel/Oil Filters: Block contaminants to avoid premature wear of precision components (e.g., fuel injectors, crankshaft bearings).

6.Diesel Atomization Check

Inspect fuel system precision parts (plunger, delivery valve, injector needle) to ensure proper atomization, preventing hard starting, incomplete combustion, and power loss.

7.Oil Passages and Small Holes Check

Key Oil Passages (align during installation):

Main bearing oil holes (align with cylinder block/neck holes)

Rocker arm bushing oil holes

Connecting rod bushing oil holes

Starter shaft bushing oil holes

Critical Small Holes (keep unobstructed):

Fuel tank vent (prevents pressure buildup/vacuum)

Crankcase breather (avoids oil leakage and degradation)

Fuel pump drain hole (prevents oil dilution)

Water pump drain hole (prevents bearing damage)

8.Break-In Check

Cold Break-In: Run the engine without injectors using external power; check oil pressure/temperatures, then drain and clean oil.

Hot Break-In: First run no-load, then under specified load. Monitor for abnormal noises, smoke, or leaks, addressing issues immediately.
