GENERATOR DIESEL UNTUK OPERASI PERTAMBANGAN

Lokasi penambangan dan operasi penambangan sering terjadi di lokasi terpencil dan biasanya akses ke jaringan listrik utama tidak memungkinkan. Hal ini menimbulkan kesulitan untuk efisiensi operasi penambangan yang mencakup ketidakmampuan untuk memberi daya pada peralatan utama, seperti power shovel, bor, excavator, dan sistem penerangan. Melakukan operasi penambangan tanpa sumber daya untuk memberikan daya ke peralatan utama dapat mengakibatkan peningkatan waktu untuk menyelesaikan tugas, pekerjaan padat karya, dan kebutuhan akan peningkatan tenaga kerja. Solusi umum adalah memanfaatkan penggunaan generator diesel komersial atau genset.

Generator diesel atau genset biasanya digunakan dalam industri pertambangan untuk melakukan operasi penambangan, bahkan tanpa akses ke jaringan listrik utama. Faktanya, tenaga yang dihasilkan dari generator diesel menyumbang sekitar 70% dari kekuatan operasi penambangan untuk membantu melaksanakan tugas-tugas mulai dari pengeboran, pemecah batu, pengangkutan benda berat dan beban material, dan transportasi sumber daya panen.

MENGAPA GENERATOR DIESEL? Ada beberapa alasan mengapa generator diesel menjadi pilihan utama untuk digunakan dalam operasi penambangan.

Generator diesel terkenal dengan daya tahan, keandalan, dan keserbagunaannya untuk menangani proyek dari semua jenis dan ukuran. Pembangunan generator diesel hanya sebagian saja.

Generator diesel membutuhkan lebih sedikit servis & perawatan jika dibandingkan dengan generator gas alam. Generator gas alam sering kali memerlukan penggantian busi atau karburator penuh, sedangkan generator diesel tidak menghadapi tantangan ini.

Satu-satunya faktor terpenting mengapa generator diesel biasa digunakan untuk operasi penambangan adalah karena jenis bahan bakarnya. Bahan bakar diesel dikenal dengan stabilitas, rasio kepadatan energi terhadap volume, dan tingkat konsumsi yang efisien. Umumnya, generator diesel membakar kurang dari setengah jumlah bahan bakar dibandingkan dengan generator gas alam, sambil mencapai jumlah hasil kerja yang sama.

Generator diesel bukannya tanpa kerugian. Generator diesel mengandalkan bahan bakar diesel untuk terus beroperasi, yang menimbulkan tantangan dalam kapasitas bahan bakar. Tidak seperti generator gas alam, yang dapat disambungkan ke pipa gas alam atau diubah menggunakan propana, generator diesel mengandalkan tangki bahan bakar diesel yang harus terus diisi ulang saat bahan bakar dikonsumsi dan habis. Bahan bakar solar juga harus disimpan dengan baik, karena kontaminan dan kelembaban dapat menyebabkan kerusakan pada generator. Ini membutuhkan perencanaan yang matang dalam hal penyimpanan bahan bakar dan transportasi untuk pengisian bahan bakar.

APA YANG HARUS DICARI DI GENERATOR PERTAMBANGAN DIESEL Generator yang Cocok Ada banyak hal yang perlu dipertimbangkan ketika memilih generator diesel untuk operasi penambangan. Ada banyak jenis proyek pertambangan dan ada pula yang lebih intensif dari yang lain. Meskipun ada banyak faktor yang berkontribusi untuk dipertimbangkan, kami akan meninjau beberapa poin utama.

Mulailah dengan menilai kebutuhan khusus proyek; termasuk tugas dan persyaratan yang membutuhkan daya generator untuk membantu menentukan peringkat keluaran daya yang diperlukan. Mengukur generator dengan benar sangat penting untuk memastikan operasi Anda dapat dilakukan tanpa masalah saat berada di lapangan.

Tinjau semua fitur generator juga untuk memastikan bahwa generator memiliki kemampuan dan kontrol khusus. Yang terpenting, pastikan untuk mengevaluasi undang-undang dan peraturan lokal atau negara bagian yang dapat mengganggu pemilihan generator Anda. Ini bisa berupa EPA, zonasi, atau undang-undang pertanahan.

Jika Anda akan menggunakan generator secara terus menerus untuk jangka waktu yang lama, pastikan untuk mencari generator utama yang memenuhi standar emisi EPA dan peraturan di negara bagian Anda.

Perlindungan Proyek dan operasi penambangan biasanya berlangsung di lingkungan terpencil yang keras dan membutuhkan peralatan yang kokoh yang dapat memenuhi tugas-tugas ini secara langsung. Saat memilih generator untuk operasi penambangan Anda, pastikan untuk mempertimbangkan penutup kedap cuaca yang dapat menjaga generator Anda aman dari elemen, serta melindunginya dari kemungkinan insiden yang mungkin terjadi di lokasi kerja.

Untuk memastikan keselamatan saat bekerja dengan generator di lokasi, pastikan ada fitur keselamatan penting di dalam generator, seperti fitur berhenti darurat. Komponen lain dapat mencakup pengukur tekanan oli, pemantauan tampilan suhu, pemutus sirkuit terlindungi, dan brankas kegagalan listrik.

Ada banyak faktor dan pertimbangan yang harus dipertimbangkan saat memilih generator diesel untuk operasi penambangan, tetapi ini adalah beberapa poin utama yang perlu ditinjau.

Suitable Diesel Generator Sets for Schools

Different schools have different numbers of teachers and students, and different quantities and types of teaching equipment. There are many places that need electricity. For example, a university usually consumes more electricity than a high school, including the power used by training equipment, teaching equipment, and scientific research equipment in schools. However, there are a wide variety of brands and models of diesel generator sets on the market currently. Which type and brand are more suitable for schools?

Normally, schools get their electricity from the municipal power supply. When the municipal power is rationed, cut off, or interrupted for other reasons, it is necessary to set up standby diesel generator sets to provide continuous power supply and ensure the normal study and life of teachers and students in schools. The types of diesel generator sets suitable for schools are mainly divided into the following categories: imported diesel generator sets, joint - venture diesel generator sets, and domestic diesel generator sets.

Which Brand of School Diesel Generator Sets is Good? And What about the Power Models?

Date: 2019 - 05 - 20 Source: Dingbo Power Views: 11959

Which Brand of Diesel Generator Sets is Good?

Parallel Operation Impulse Current Calculation Method 2

This article continues to introduce the calculation method of impulse current for parallel operation of diesel generators.

The expression of the transient inrush current during the no - load connection of a doubly - fed induction generator is derived. The influence of the voltage amplitude difference and the phase difference on the inrush current is analyzed, and corresponding measures to suppress the inrush current are proposed. When a three - phase synchronous generator operates symmetrically, the effect of a single - phase can be equivalently considered. Through the finite - element modeling of a single - phase generator, it is verified that the frequency difference has little influence on the inrush current. The closing operation for paralleling does not select the moment when the frequency between the generator and the system is the same. A slight frequency difference makes it easier for the main generator to pull the generator to be paralleled into synchronization. Therefore, the main factors affecting the magnitude of the inrush current are the voltage amplitude difference and the angular difference.

Starting from the analysis of the causes and impacts of the inrush current during the paralleling process of a synchronous generator, the calculation formula of the inrush current when there are both voltage amplitude differences and phase differences is derived. Through the calculation of an example of generator set paralleling, a reasonable range of parameter differences is given, providing a theoretical basis for the parameter setting of the synchronization locking device for generator paralleling.

Regarding the causes and impacts of the inrush current during the paralleling process of a generator, the Laplace transform is used to give the calculation formula of the generator inrush current when there are voltage amplitude differences and phase differences. Taking the actual paralleling of a diesel generator set as an example, a reasonable range of parameter differences is calculated. Through the above analysis and calculation, the following conclusions can be drawn:

1.The magnitude of the inrush current during the parallel operation of a three - phase synchronous generator is mainly determined by the comprehensive effect of the voltage difference and the phase difference at the moment of closing for paralleling. The frequency difference between the generator sets at the moment of paralleling has little influence on the magnitude of the inrush current. An appropriate frequency difference can enable the generator sets to quickly enter the synchronous operation state, but an excessive frequency difference will cause the generator sets to experience long - term oscillations and may even lead to disconnection.

2.When operating the parallel operation of generator sets of any capacity, the voltage amplitudes on both sides of the system to be paralleled are first adjusted to be equal. However, in actual operation, when the parallel circuit breaker is closed, there are always both voltage amplitude differences and angular differences. Therefore, the inrush current is caused by the combined effect of the voltage amplitude difference and the angular difference.

3.Setting a reasonable parameter range for the parallel circuit breaker and the synchronization device can reduce the inrush current caused by the voltage amplitude difference and the angular difference, improve the success rate of parallel operation, speed up the paralleling process, and ensure the safe and stable operation of the system.

Inspection and Installation of Oil Cooler for Yuchai Generator Set

All the oil coolers used in Yuchai products are plate - fin type. The inner layer is the core plate 6, which serves as the oil cooling circulation passage. There is an oil bypass valve installed on it, and the opening pressure of the bypass valve is 0.55 MPa. Outside the core plate is the cooling water chamber. Part of the water from the water tank circulates through the chamber to reduce the oil temperature. See the figure below.

1.Radiator cap 2.Gasket (III) 3.Bolt M10×35 4.Gasket (I) 5.Gasket (II) 6.Core plate 7.Oil outlet connector 8.Radiator cap 9.Drain switch 10.Bypass valve spring 11.Bypass valve plug 12.Bypass valve ball

Cleaning

The key is to clean the oil passages inside the plates. Pour diesel into the core plate and shake it several times for cleaning. Remove the bypass valve and clean its spring and inner hole. However, note the number of turns when unscrewing the plug. When installing, the number of turns for screwing in must be the same to avoid changing the opening pressure.

Inspection

During use, if oil is found in the water, check whether the core plate is desoldered. The method is to block the oil outlet of the core plate, inject air at 0.3 MPa from the oil inlet at the other end, and check for air leakage in the water.

Installation

The oil cooler of the Yuchai generator set is relatively long. When installing, ensure that the sealing gasket is not twisted. Tighten the fastening bolts twice, starting from the middle and moving towards both ends.

Common faults of the Yuchai generator set oil cooler

· Core plate leakage: In this case, there is oil in the water tank, which is caused by desoldering or false soldering at the copper tube joints of the core plate.

· Cracks in the housing or damaged sealing gaskets.

Note: In extremely cold winter weather, drain the water from the cooler to prevent it from freezing and cracking.

Gas Ring of Piston Ring in Diesel Generator Set Part 2

This article continues to introduce the gas ring function and working principle of the piston ring in diesel generator sets.

In order to improve the working conditions of the piston rings and ensure better fit between the piston rings and the cylinder, some piston rings use different cross-sections, and special attention should be paid during installation. The basic cross-sectional shape of an air ring is rectangular. Rectangular rings are easy to manufacture and widely used, but their break in performance is relatively poor and cannot meet the increasingly stringent requirements of engines. This ordinary compression ring can be installed freely in the gas ring groove. Some engines use a conical ring structure. The working surface of this ring is designed with a cone angle of 0.5 ° to 1.5 °, which reduces the contact surface between the working surface of the ring and the cylinder wall, allowing for faster wear in. The cone angle also has the function of scraping oil. But the wear of the conical ring is fast, which affects its service life. The side with sharp edges faces downwards during installation.

Some internal combustion engines use twisted rings. Cut off a portion of the upper edge of the inner circle or the lower edge of the outer circle of the twisted ring to form a stepped cross-section. This type of cross-section is asymmetrical inside and outside. After being compressed when the ring is installed in the cylinder, it produces a significant inclination of the cross-section under the action of asymmetrical internal forces, forming a conical surface with a small upper part and a large lower part on the outer surface of the ring. This reduces the contact area between the ring and the cylinder wall, making it easy to break in and has the function of scraping oil downwards. Moreover, the upper and lower end faces of the ring are in contact with the corresponding upper and lower end faces of the ring groove, which not only increases the sealing performance but also prevents the piston ring from moving up and down in the groove, causing pump oil and wear. This type of ring is currently widely used. When installing a twisted ring, attention must be paid to its up and down direction, and it cannot be installed in reverse. The inner cut should face up and the outer cut should face down. In some internal combustion engines with high heat loads, trapezoidal rings are often used to improve the anti coking ability of the gas ring. The clearance between the end face of this ring and the ring groove changes with the lateral swing of the piston under lateral force, which can crush the carbon deposits in the ring groove and prevent the piston ring from getting stuck due to adhesive buildup. This type of ring can be installed freely like a regular gas ring.

There is also a form of gas ring bucket surface ring, which has a convex circular arc working surface and is wedge-shaped with the cylinder wall in both directions, making it easy to break in, with good lubrication performance and strong sealing. This type of ring has been widely used to strengthen internal combustion engines. This type of ring, like a regular compression ring, can be installed freely in the gas ring groove.

The Function and Cooling Method of The Engine's Cooling System

The working principle of the cooling system of a diesel generator set is heat transfer. Heat always moves from hot objects to cold objects. There are three ways of heat transfer: conduction, convection, and radiation. Conduction refers to the heat transfer between two solid objects. For example, heat is transferred from the valve stem to the valve guide. Due to both objects being solid, heat is transferred from the hot air rod to the cold valve guide through conduction. For example, heat is transferred from the air duct to the cylinder head through conduction. Heat can be transferred through convection. Convection is the heat transfer that occurs through the circulation of heat in a liquid or gas. Through convection, the heat from the hot cylinder body is transferred to the coolant, and when the hot radiator components transfer heat to the surrounding cold air, convection also occurs.

Radiation is a way of heat transfer. Radiation is the heat transfer that occurs by converting thermal energy into radiant energy. Any hot object emits radiation heat through conduction, and the hotter the object, the greater the radiation energy. When the diesel engine is hot, some of the heat is converted into radiation, approximately 8%. The cooling system removes excess heat from the engine based on these principles. For example, when a person approaches a running engine or other heat source object, although they have not approached it, they can already feel that the engine is hot, which is due to thermal radiation. In order to ensure the optimal operation of the unit engine, a cooling system is necessary. Engine manufacturers typically use two types of cooling systems: hot air (air) cooling systems and liquid (water) cooling systems, corresponding to air-cooled engines and liquid cooled engines.

Function and cooling method of cooling system

When an internal combustion engine is in operation, the combustion of fuel in the cylinder generates a large amount of heat, causing the gas temperature inside the cylinder to reach up to 22002800K (about 19002500C). About one tenth of the heat released by fuel combustion is absorbed by internal combustion engine components. In this way, if the components that come into direct contact with high-temperature gases (such as cylinder liners, cylinder heads, pistons, valves, etc.) are not cooled in a timely manner after being heated, the moving components may expand due to heat and damage the normal clearance, or get stuck due to the failure of lubricating oil. The mechanical strength of each component may also decrease or even be damaged due to high temperature, leading to a decrease in cylinder filling and abnormal combustion. Therefore, in order to ensure the normal operation of internal combustion engines, it is necessary to cool these components that work under high temperature conditions. Of course, the cooling of internal combustion engines must be moderate. If the cooling is excessive, on the one hand, due to excessive heat loss, the amount of heat converted into useful work decreases; On the other hand, the temperature is too low Not conducive to the formation and combustion of combustible mixtures.

The working temperature of an internal combustion engine, whether too high or too low, will reduce its power and economy. The function of the cooling system is to maintain the most suitable working temperature of the internal combustion engine, and to exert its good economy, power, reliability, and durability.

Diesel Generator Operating Guide: How to Maximize Power Output and Conserve Energy?

In modern society, diesel generators have been widely used in different fields, such as industrial, commercial, medical, communication and emergency relief. They can serve as the main power source or the backup power supply and provide reliable power. Today, Dingbo Power will share several tips on how to use diesel generator sets efficiently, so that you can maximize the power output and conserve energy.

Determine your power requirements

Determining your power needs is an essential precondition for efficient use of diesel generators. You need to figure out the maximum power required, common load rates, continuous operating time, and the need for backup power and so on before buying a diesel generator. Through an accurate power load analysis, you can select a diesel generator set that meet the actual demand, avoiding buying an undersizd generator or oversizd generator.

With the progress of technology, many energy-saving diesel generator sets are now available on the market. These units typically use advanced combustion technology, optimally designed cooling systems and efficient alternators to significantly reduce fuel consumption and emissions while maintaining power output. When choosing a diesel generator, you should focus on some key indicators, such as its thermal efficiency, fuel consumption rate and emission standards.

Install the generator correctly

The installation location of a diesel generator set has an important effect on its operating efficiency and lifespan. You should choose a place with good ventilation, and appropriate temperature and humidity to install the generator set. The installation area should be away from flammable and explosive materials. Meanwhile, considering the impact of noise and vibration caused by diesel generator, corresponding sound insulation and vibration absorption measures should be taken to ensure that the unit does not cause disturbance to the surrounding environment.

During installation, please follow the instructions provided by the manufacturer to ensure that the diesel generator is firmly fixed, the fuel system and cooling system are correctly connected, and the electrical circuit is safe and reliable. In addition, it is also necessary to configure the necessary fire protection facilities to deal with the possible fire risks.

Maintain and service your diesel generator regularly

Regular maintenance is the key to keep diesel generators running efficiently. This mainly include regular inspections, cleanliness, fuel quality, oil changes, battery maintenance, load testing, and professional servicing. You should periodically check the status of consumable parts such as oil, coolant and fuel filters, and timely replace any damaged or aged parts according to the manufacturer’s instructions. Clean the radiator and air filter regularly to keep the generator heat dissipation and air intake smooth. Check and adjust parameters like valve clearance and injection pressure regularly to ensure that the engine is in the best working condition.

Avoid overloading your diesel generator

Generally, diesel generators will be most efficient at their rated load. However, diesel generators running at full load for a long time can lead to some issues such as excessive wear and generator failure. Thus, for best performance and longevity, it's generally recommended to operate diesel generators within their optimal load range rather than at maximum capacity. In actual use, the output power of the your diesel generator should be adjusted reasonably according to the load demand. If necessary, you can use multiple generators in parallel operation and adjust the number of operating units according to load changes to achieve balanced load distribution.

Today, Dingbo Power diesel generator sets are equipped with intelligent control systems, which can monitor the unit's operating status, load conditions, fuel consumption and other key parameters in real time, and automatically adjust the generator's operating parameters according to the preset logic to achieve the optimal power output and energy saving effect.

Use high-quality diesel fuel

Fuel quality directly affects the combustion efficiency and emission performance of diesel generator sets. Using high quality, low sulfur diesel fuel can reduce fuel consumption, reduce carbon accumulation and harmful emissions. Thus, you should use the high quality fuel from reputable sources.

In addition, diesel generator sets will produce a lot of waste heat during operation. Through the implementation of waste heat recovery technology, this waste heat can be used for heating, hot water supply or preheating air intake purposes. This not only improves energy efficiency, but also reduces energy consumption and emissions.

In short, to maximize the power output and conserve energy of your diesel generator set, you need to choose right size generator, install the generator correctly, maintain the generator regularly, avoid overloading and use high-quality fuel.
