Diesel Generator Tech

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 - c...

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 me...

Diesel generators are an essential backup power source and they can provide reliable power for extended periods. When using a diesel generator set, you need to pay attention to the cooling water temperature. If the coolant temperature is too high, it may cause problems such as stuck piston, cylinder scoring, decreased engine oil viscosity and reduced generator performance. What may cause the excessively high water temperature of diesel generator? Reasons for excessively high water temperature of diesel generator set Clogged radiator If the surface of radiator is mixed with engine oil, a sludge mixture of oil and dust can block the radiator and result in difficult to dissipate heat. Improper use of coolant Coolant is an important cooling material to reduce the genset temperature and water temperature of the unit. Faulty coolant or a lack thereof will seriously affect the cooling performance and even lead to a rapid rise in temperature. The engine will overheat. Cooling water pump ...

China has a vast territory, and there are many high - altitude areas in the central and western regions, including Tibet, Qinghai, Yunnan, Guizhou, Sichuan and other places. In the remote areas of these provinces and autonomous regions, it is often difficult for the power supply to reach the load center. Therefore, diesel generator sets need to be purchased as the common power source. In the plateau area, due to the high altitude, the oxygen in the air is relatively thin. People living on the plain usually have altitude sickness when they go there, which is generally manifested as mild headache, insomnia, mild chest tightness, excessive excitement, etc. The working principle of a diesel generator set is to obtain energy through the combustion of diesel. So, will the plateau environment have an impact on the use of diesel generator sets?   Due to the low air pressure and thin air in the plateau area, the oxygen content in the diesel generator set is low, and the ambient temperatu...

When designing the structure of a diesel generator soundproof enclosure, a number of important factors should be considered to ensure the comprehensiveness and practicality of its functions. For example, an acoustic enclosure should be able to house a diesel generator, including the diesel engine, alternator, batteries, circuit breaker, control system and noise reduction components and other relevant parts and accessories. This requires the designers to give due consideration to the rational layout of individual components in order to leave the necessary space for acoustic noise reduction, and to ensure the overall structure is stable and coordinated. Generally, the silent generator enclosures are designed as a rectangle. This design has strong adaptability and mobility. With superb manufacturing technique, the enclosures are suitable for both indoor and outdoor use. In order to save space and reduce length, the ends of the enclosure are sometimes cut at an oblique angle, which can be...

Diesel engines of generator sets may develop various faults during operation due to diverse causes. If the root cause is not identified and addressed promptly and you allow the engine to continue operating with faults, it can lead to reduced power, increased fuel consumption, and even catastrophic failures. This article briefly introduces the causes of diesel engine failures and common methods for diagnosing them. Causes of diesel engine failures Diesel engine faults generally fall into two categories: 1. Gradual natural wear: Includes corrosion, fatigue wear, and abrasive wear. This is a normal process that can only be mitigated through proper maintenance and usage to extend the engine’s lifespan. 2 Sudden failures: Caused by improper operation or poor maintenance, such as insufficient oil/water levels, clogged fuel lines, water ingress, dirty filters, or incorrect fuel injection/valve timing. While fault causes vary, systematic analysis based on symptoms can simplify troubleshooting....

Characteristics of salient-pole generators: The air gap between the stator and the rotor is non-uniform. The air gap under the pole shoe is relatively small, while the air gap between the two poles is relatively large. That is to say, the magnetic reluctances of the direct axis and the quadrature axis of the salient-pole synchronous generator are different. Therefore, the armature magnetomotive force will generate different armature fluxes at different positions in the air gap. As known from the analysis of the armature reaction of synchronous generators, under normal circumstances, the armature current can be decomposed into two hypothetical current components, namely the direct-axis current component Id=Issin⁡ΨI_d = I_s\sin\PsiId=IssinΨ and the quadrature-axis current component Iq=Iscos⁡ΨI_q = I_s\cos\PsiIq=IscosΨ. These two components respectively establish the magnetomotive forces FdF_dFd and FqF_qFq, and these two magnetomotive force components respectively generate the direct-ax...

Spark plugs, commonly known as spark igniters, are used to discharge the pulsed high-voltage electricity sent by high-voltage wires (spark plug wires). They break down the air between the two electrodes of the spark plug, generating an electric spark to ignite the air-fuel mixture in the cylinder. The main types include: standard spark plugs, insulator projection spark plugs, electrode spark plugs, seat spark plugs, multi-electrode spark plugs, surface discharge spark plugs, etc. Spark plugs work in conjunction with the ignition system and the fuel supply system to make the engine run, and to a large extent, jointly determine the performance of the engine. How much do you know about the maintenance of spark plugs for 200KW natural gas generator sets? For 200KW natural gas generator sets, the spark plugs should be maintained every approximately 250 hours of operation. The specific maintenance cycle depends on the actual operating environment of the spark plugs.   Clean the carbon...

Silent generator sets are widely used in places with strict environmental noise requirements, such as post and telecommunications, hotels and buildings, entertainment venues, hospitals, shopping malls, industrial and mining enterprises, etc. They are used as regular or backup power sources. When purchasing and installing silent generator sets, it is necessary to comprehensively consider the possible impacts of various complex climates on the generator sets to ensure their normal operation. The use of silent generator sets is greatly affected by the surrounding environment. When the environmental climate changes, silent generator sets will also change accordingly.
