Key Knowledge Points of Shangchai Generator Set

Diesel generator sets are widely used in various fields such as industry, agricultural breeding, medical care, military, and schools. For users, it is becoming increasingly important to understand the knowledge and application of diesel generators. Today, the editor will share two pieces of knowledge with you. One is the usage instructions for generator sets at different altitudes and temperatures, and the other is the functions of the generator coupling.

The main components of a diesel generator set are the engine and the generator. Normally, we need an excellent diesel generator set to meet our power needs. Under different environmental temperatures and high - altitude conditions, what is the correct way to use it? The editor has summarized the following points for you:

Environmental temperature and altitude

The engine can operate under the following conditions without power adjustment:

For an engine with a rotational speed of 1800 r/min, the altitude is below 1525 m (5000 ft) and the environmental temperature is below 40°C (104°F).

For an engine with a rotational speed of 1500 r/min, the altitude is below 1525 m (5000 ft) and the environmental temperature is below 40°C (104°F).

When the generator operates beyond the above - mentioned conditions:

When the altitude is higher than 1525 m (5000 ft), for every 300 m (1000 ft) increase in altitude, the power should be reduced by 4%.

When the environmental temperature is higher than 40°C (104°F), for every 11°C increase in temperature, the power should be reduced by 2% (for every 10°F increase, the power should be reduced by 1%).

The above are the usage instructions for the Shangchai generator set at different altitudes and environmental temperatures, provided for your reference.

What are the functions of the generator coupling?

1.Connection device: The coupling is a connecting device used to connect power - output mechanisms such as engines and driven mechanisms. It connects working components on different working planes so that they can work together.

2.Power transmission component: When two different mechanisms are connected by a coupling, the driving mechanism drives the driven mechanism to work under the fixation of the coupling, transmitting torque and power. Some couplings can not only transmit torque and power but also have different degrees of axial, radial, and angular compensation capabilities.

3.Shock - absorption and buffering: The coupling has the functions of shock - absorption and buffering.

The functions of the coupling are roughly the above three types. According to their functions, couplings can be roughly divided into three categories: rigid couplings, flexible couplings, and safety couplings. Rigid couplings can only transmit motion and torque. Flexible couplings can not only transmit motion and torque but also have different degrees of axial, radial, and angular compensation capabilities, as well as different degrees of shock - absorption and buffering functions. Safety couplings transmit motion and torque and provide overload safety protection. Although the coupling is small, it is of great significance to a generator set. Therefore, we also need to pay attention to it and understand it better so that we can handle fault problems calmly.

What Causes Your Diesel Generator Difficult to Start in Summer?

As important power supply equipment, diesel generator sets are widely used in various industries around the world. In hot summer, ensuring the stable and reliable power supply is particularly essential for many enterprises. However, many factors such as high ambient temperature and high humidity may prevent diesel generators from starting smoothly. This not only affects the normal operation of the equipment, but also causes inconvenience to the production and operation of enterprises. Today, Dingbo Power will share several common reasons for diesel gensets struggling to start in summer.

What causes your diesel generator difficult to start or fail to start in summer?

Generally, many factors can lead to generator failure. The following are several top reasons for diesel generator not to start in summertime:

The reduced viscosity of engine oil

The right oil in a generator serves several critical functions: lubrication, heat dissipation, corrosion protection and cleaning. Oil viscosity refers to the thickness of the oil and its ability to flow at different temperatures. You should follow the manufacturer's recommendations for oil type and viscosity and use the best oil for your generator. Viscosity grades are recommended based on several criteria, including ambient temperatures.

In a hot summer, the viscosity of the oil will be reduced. This will can lead to inadequate lubrication, resulting in increased friction and potential engine failure. Therefore, when your generator operates in a higher temperature environment in summer, a higher viscosity oil that won’t thin out too much is preferable.

Defective fuel system

In the high temperature environment, the volatility of the fuel is enhanced, which makes it easy to form an air resistance in the fuel tank and the fuel pipes, affecting the supply of fuel. Meanwhile, high temperatures may also lead to aging and cracking of fuel pipes, further aggravating fuel supply problems. These problems can cause the diesel generator difficult to start .

To fix the problem, you should check the fuel tank and fuel lines and other components in fuel system regularly and replace the aging and cracked parts in time. Additionally, sunshades or other insulation measures can be installed above the fuel tank to reduce the volatility of the fuel. To prevent the generator starting failure, it’s also important to use high-quality fuel and ensure sufficient fuel.

Weak or dead battery

Diesel generator sets rely on batteries to start. However, high temperatures in summer may affect battery performance because it makes the electrolyte inside the battery easy to evaporate. In addition, the high temperature may also oxidize the battery plate and reduce the discharge capacity of the battery. A battery failure could also be due to dirty or loose connections. If the battery fails, the generator will not start.

You should check the the electrolyte level height and concentration of the battery regularly in summer and add distilled water or electrolyte timely if necessary. Keep the battery surface clean and dry to avoid plate oxidation. In a high temperature environment, you can consider using high temperature resistant batteries or taking other cooling measures. In addition, charge and discharge the battery periodically to ensure that the performance of the battery meets the requirements.

Problematic starting mechanical parts

The starting mechanical parts of the diesel generator such as the starter may be deformed due to thermal expansion in a high temperature environment, resulting in a smaller fit clearance and an increased starting resistance. High temperature may also cause inadequate lubrication on starting machine parts, further aggravating the difficulty of starting. Moreover, dust and impurities in the air in a high temperature environment increase, which can cause air filters to get clogged. This will lead to insufficient engine intake and insufficient combustion, which makes it difficult to start the diesel generator set.

Therefore, you should pay special attention to the starting mechanical parts of the diesel generator set in a hot summer. Timely maintenance and adjustment should be carried out. Inspect the diesel generator starting mechanical parts and the fit clearance periodically. Any damaged parts should be replaced in time. For the components deformed by thermal expansion, you can take appropriate adjustment measures to restore them to their original state. In addition, clean and maintain the starting mechanical parts regularly to ensure its normal operation. A clogged air filter can prevent the carburetor from getting the air needed for combustion. You should check if it looks dirty, replace it if necessary.

Diesel generator struggling to start or failing to start is a common problem in summer. Find out the causes and you can fix the problem accordingly. If you have a problem with generator set starting or look for a new diesel generator, feel free to contact Dingbo Power and we will gladly help you.

What Can Cause A Diesel Generator Fail to Start? 11 Common Causes

Diesel generators have a reputation for being robust and reliable. However, like any other piece of machinery, they cannot be 100% reliable. It’s frustrating that your diesel generator fails to start in the event of a power cut. Understanding the common reasons why a diesel generator won’t start is essential for proper troubleshooting and maintenance. In this article, Dingbo Power explores 11 common causes for generator not starting and provides you with measures to fix it as well .

Lack of fuel  

If your diesel generator runs out of fuel or has an insufficient amount of fuel, it won’t be able to start as usual. Therefore, when you experience generator failure, you should first check the fuel tank level and fill the fuel tank if the level is low.

Poor or contaminated fuel  

Contaminated fuel, such as water or debris in diesel, can prevent your generator from starting smoothly. Low-quality fuel can’t support the operation of the diesel engine. It is essential to use clean and high-quality diesel. Remember that diesel fuel can last for around 12 months before serious degradation. If you have your fuel stored in the tank for long periods, consider testing the fuel to ensure it does not cause a fault in the future. Regularly monitor fuel storage conditions and address any issues promptly. If the failure is caused by contaminated fuel, you can fix the problem by draining the fuel in the fuel tank and filling the fuel tank with high-quality fuel. Diesel generators usually struggle to start in cold winter, read also useful tips on how to start a diesel generator in the cold.

Air in the fuel system:  

If you fill the fuel tank properly but your diesel generator starts and then stops, there might be too much air in the fuel. Air can enter the fuel system sneakily when your engine runs out of fuel. Fuel filter replacement, leaks or repairs can also lead to airlocks. If this happens, it can disrupt the combustion process, causing startup issues. You can bleed your diesel generator by following the manufacturer’s recommended procedures. Remove the air in the fuel system and ensure proper fuel flow.

Battery failure  

The battery is mainly used to start the diesel engine of the diesel generator. A battery failure can also prevent the diesel generator from starting. If your generator won’t start, it could be due to a dead battery or faulty connections. Check the battery voltage with a voltmeter or perform a load test to ensure it has sufficient power. Make sure the battery charger works properly. If it malfunctions, consider replacing it. Corrosion on battery terminals can hinder the flow of electricity and cause the generator won’t start. You can use a wire brush to clean the terminals and apply a protective coating to prevent future corrosion. Clean terminals and tighten connections regularly to prevent a potential for failure.

Clogged air filter  

A dirty or clogged air filter can severely cut off fresh air flow to the carburetor and lower the engine's performance and horsepower. You can check the air filter and clean or replace it if it looks dirty. Follow the manufacturer’s recommendations and regularly replace the air filter. 

Blocked fuel filter  

A fuel filter is mainly designed to stop fuel impurities from getting into the engine or parts of the fuel system where they can cause problems. If the fuel filter becomes dirty, your machinery performance will be affected negatively. Blocked fuel filters will make starting difficult or impossible. Check the fuel filter and replace it if it’s dirty. It’s important to follow the user manual to change the fuel filter regularly.

Faulty glow plugs:  

Glow plugs are heating devices that aid in starting diesel engines. Faulty glow plugs can cause the engine to misfire. Glow plugs usually fail because of corrosion, overheating, mechanical damage, or metal fatigue. You can use a clamp-meter to test the glow plugs and replace them if necessary.

Low coolant levels  

The coolant in a diesel generator set can maintain the operating temperature and ensure the overall performance of the engine. Without sufficient coolant, your engine could overheat. Overheated engines risk catastrophic failure, where they seize up entirely. Maintaining proper coolant levels is crucial to protect your engine from overheating damage. You need to check the coolant level regularly and top it up as necessary.

Low oil levels  

Engine oil serves the crucial function of lubricating generator's moving parts and guaranteeing their smooth operation. Running with low oil level or no oil can cause severe wear and destruction to certain parts of your engine. Check the engine oil level regularly with the dipstick. Add more oil if the oil level is low. Please use the recommended type and grade of oil specified by the manufacturer.

Generator starter motor fault  

A starter motor assembly is used to take a stored energy and convert it into mechanical rotation to crank the engine fast enough to begin the engine's ignition sequence.

Everything You Need to Know About Diesel Generator Load Bank Testing

Diesel generators provide a reliable source of power to your facility or business during an emergency situation when the mains power fails or in places without connection to a power grid. To ensure your generator works smoothly when needed, it’s necessary to perform a load bank test periodically. In this article, we’ll cover what you need to know about diesel generator load bank testing.

What is the load bank testing of a diesel generator?

Diesel generator load bank testing is an essential part of a comprehensive preventative generator maintenance routine. This task involves using a load bank to put artificial loads on the generator to test the Uninterruptible Power Supply (UPS) and generator under load conditions. During the test, all parameters are monitored and documented and the information about the specific generator tested will be showed in the load bank test report. With the report, you will see a clear picture of the overall health of the emergency stand-by power system.

With a proper load bank testing, you can verify the generator’s ability to deliver the power you need during a power outage and ensure efficient operation of a genset.

What is a load bank?

A load bank is a device with kilowatt rated sizes and battery type cables, which is designed to provide electrical loads for testing power sources and UPS. It can be used to test the system’s ability to generate power and maintain voltage and current levels within specified limits. Load banks can help test and improve the health of generator and its components. During load bank testing, all the data, such as PSI, time, volts, Amps, Hertz, oil, kW, water temperature and exhaust temperature, can be recorded that offers a more thorough look into the overall health of the gen set.

There are four primary types of load banks: resistive, reactive, resistive-reactive and inductive. Each of them works differently, you need to choose the right kind of load bank for your generator set and application.

Benefits of performing a load bank testing

Performing load bank testing in conjunction with periodic maintenance is recommended by the National Fire Protection Association (NFPA). There are many benefits of conducting a diesel generator load bank test:

Verify the reliability of generator: The failure of diesel generator set during an emergency situation could result in catastrophic conditions. By conducting a generator load bank testing, you can ensure the generator is capable of reaching its rating during an actual emergency. The test verifies the genset's capabilities opposed to just routinely starting it up. You can also discover potential genset problems in a controlled situation and take remedial actions. The test helps to determine if your generator functions properly and efficiently at any critical point in time.

Prevent wet-stacking: If your diesel engine generator set is not used frequently or only runs on light loads, it can be prone to experience unburned fuel and soot buildup in the exhaust system. This is called wet-stacking. When wet-stacking occurs, you may find back smoke during generator operation or excessive build-up of carbon and oil around the engine turbo. Your generator is likely to perform poorly or even fail to work. During a load bank testing, your machine is run at full operating power and temperature, which can burn off the residue and build-up and reduce wet stacking issues.

Increase your generator’s lifespan: As your generator ages, it’s likely to experience increasing problems over time. In addition to eliminating wet-stacking, the load bank testing can spot and minimize potential weaknesses in a diesel generator system. Regular load bank testing increases the lifespan of your generator by regularly running the exhaust valves and turbo-chargers and reducing the risk of internal damage .

Reduce costs: Diesel generator load bank tests can reveal generator issues before they become serious problems. Problems discovered early can be significantly less expensive. Preventing future mechanical failures reduces costs in the long term.

How to perform a diesel generator load bank test?

To conduct a generator load bank testing, you can follow the steps below:

Connect the load bank to the generator using the attached cables.

Inspect the fluid levels and make sure your generator has sufficient fuel, oil and coolant to operate.

Start and run the generator and allow it to reach its standard operating temperature.

Begin applying loads in descending voltages until the load carried reaches 50% of the generator’s maximum continuous rated load.

Check the voltage and amperage within each leg with an ammeter.

Monitor the generator for signs of overheating and any abnormal noises.

When the test is gradually wound down, remove the loads methodically, allowing the generator to run under progressively lighter loads for about an hour.

Once all loads are removed, allow the generator to cool down before completely shutting the unit down.

The load bank test will provide timely identification of problems with the generator and you can take corrective actions if any problem is found.

Difference between generator load bank testing and building load testing

Many users often confuse a generator load bank testing with a building load testing. In fact, both of them are important, but they are not one thing.

A building load test is a test that transfers electrical power from the building’s power source to the backup generator for a short period of time. To perform this test, a qualified technician shuts off the main power supply to the building simulating a power outage, which allows the backup power system to take over. It may require 30 minutes to complete the test. This test aims to make sure the generator is running properly in the event of a mains failure. It should be performed once a month or even more often depending on the type of facility.

A load bank testing verifies generator system performance under simulated power outage conditions. During the test, connections between the diesel generator and the building is disconnected. A load bank will be connected instead to the generator without disruption to commercial service. It helps ensure that the generator can handle a full load and identifies potential problems during use. A generator bank load testing usually lasts between two and six hours. It should be performed either yearly or every three years depending if the generator makes 30% load during the building load test.

Understanding the Function of Diesel Generator Fuel Injector

If symptoms such as misfires, rough idling, or poor fuel economy occur during the operation of your diesel generator set, it is likely that your fuel injectors are clogged. A malfunctioning fuel injector can even cause the difficult starting of engine. In this article, we’ll introduce the function of diesel generator fuel injector and you’ll have a basic understanding of this device.

What is the function of fuel injector in diesel generator?  

Diesel fuel injectors are an important component of diesel fuel system. The function of the fuel injectors is to deliver a precise amount of atomized and pressurized fuel into each cylinder. This helps to ensure efficient combustion, increased power and fuel economy, and smooth operation of diesel engine. Fuel injectors can optimize fuel consumption in traditional diesel engines and play a crucial role in their performance and efficiency.

Generally, diesel fuel injectors are made of durable materials such as stainless steel or high-strength alloys. They have to be able to withstand the high pressures and temperatures inside the cylinder and still deliver the fuel in a fine mist. They are quite complicated: the injector has a high micron filter on the top inlet side which corresponds to small hypodermic sized holes on the bottom for the atomizing of the diesel fuel.

Typically, diesel fuel injectors can be divided into three types: mechanical, common rail, and unit injector systems. Mechanical fuel injectors open and close the injector valve by using a mechanical linkage. Common rail systems use high-pressure fuel pumps to deliver fuel to a central rail, which is then distributed to the individual injectors. Modern diesel fuel injectors in these systems often use piezoelectricity. Unit injector systems combine the fuel pump and injector into a single unit.

How does a diesel fuel injector work?  

The fuel injection system controls the flow of fuel into the combustion chamber. A diesel fuel injector consists of a solenoid, a nozzle, and a needle within the injector body. The solenoid acts as an electromagnetic valve. The fuel injectors in most electrical diesel engines are controlled by the ECM (Engine Control Module). The ECM adjusts the amount of fuel injected into the engine cylinder to meet a variety of operating conditions. It does so by collecting and processing readings from various sensors. The amount of fuel to be pumped is decided by the electronic control unit (ECU). After calculating the amount of fuel required, the fuel injectors inject the fuel via their nozzles connected to the combustion chamber.

Modern diesel engines are direct injection, meaning fuel is injected directly into the combustion chamber. Fuel is delivered into the chamber right into the top of the piston. Direct injection is used at higher speeds to provide more power and less chance of knocking.

 What may happen when diesel generator fuel injectors malfunction?  

Fuel injectors in a diesel generator rely on clean diesel fuel and oxygen. If you use poor-quality diesel fuel, the fuel injectors won’t work well and issues like carbon deposits buildup in the cylinder and accelerated wear of the cylinder barrel and piston ring may arise. There might be a few possible symptoms including unstable idle speed, increased fuel consumption, weak acceleration, difficulty in starting, and excessive emissions. It’s suggested that you always purchase clean and high-quality fuel from reputable suppliers to ensure efficient and optimal performance of your generator. Additionally, water contamination in fuel can also wear out and destroy the injectors over time. Remember to replace Oil filters regularly.   

If diesel fuel injectors are leaking, you may smell the diesel in the vicinity of the generator. Due to the problem, the fuel consumption amount may increase suddenly and the generator is difficult to start. This may be caused by an old O-ring or a crack in the injector body. You need to find out the cause and replace the relevant components.

If there is an electrical fault interfering with the correct timing of the injector(s), or the injector gets clogged or its component becomes faulty, it will lead to decreased engine power and efficiency. You need to check the fuel injectors and replace them if necessary. We suggest that you contact a professional technician if you don’t have that much experience.
