Diesel Generator Tech

Sometimes, we can see small square cabins beside the roads in some residential areas. Occasionally, we may even spot workers opening them for inspections. During power outages, we can hear noises coming from inside. In fact, these are silent diesel generator sets, which are standard diesel generator sets equipped with silent enclosures. When some customers purchase diesel generator sets, due to certain limitations such as the absence of a built - in generator room, the units need to be installed outdoors. For those who need protection against wind, frost, rain, and snow but have no requirement for noise reduction, it is more cost - effective to install a rain - proof cover. If there are noise requirements, a silent enclosure should be installed. Some users need diesel generator sets for field construction and have special requirements, such as needing a silent, mobile, and rain - proof generator set. Generator sets with silent and mobile functions are all rain - proof, but rain - proo...

If there are any debris, dust, or dirt, remove them and make sure the airflow isn't obstructed.   Use block heaters or jacket water heaters With block heaters or jacket water heaters, engines on diesel generator sets can be kept heated up and started easily in ...

Diesel generators   are widely used as reliable power sources in various settings, from residential and commercial applications to industrial and emergency situations. Understanding the basic components, operation, and maintenance of diesel generators is crucial for their effective use. This article provides an overview of essential knowledge regarding diesel generators. Components of a Diesel Generator A diesel generator consists of several key components that work together to produce electricity. The main parts include: Diesel Engine: This is the primary power source that drives the generator. The engine converts diesel fuel into mechanical energy through combustion. Alternator: Connected to the engine, the alternator converts the mechanical energy into electrical energy. It consists of a rotor and a stator that work together to generate alternating current (AC). Fuel System: This includes the fuel tank, fuel pump, and fuel lines, which supply diesel to the engine. Cooling System...

  The viscosity of diesel generator oil indicates the internal friction resistance when the oil flows. The viscosity of engine oil is related to the engine temperature. When the engine temperature is low, the viscosity of engine oil is high; On the contrary, the oil viscosity is low. When the viscosity of engine oil is high, its flowability is poor but its sealing performance is good, resulting in less leakage. If the viscosity of the oil exceeds the specified value, the flow resistance of the oil in the lubrication system will increase, and the pressure will also increase. From this, it can be seen that when the engine temperature is low or the viscosity of the oil itself is high (due to improper selection of the oil grade, i.e. the oil grade is not suitable for the ambient temperature, such as selecting oil with high viscosity in summer in winter), the oil pressure will be high. From the lubricating oil circuit of  diesel generators , it can be seen that the flow resistance ...

When Volvo generators cannot start normally, the reasons should be found from aspects such as starting work, diesel engine fuel supply system, and compression. Today, let's share the reasons why a   Volvo generator   fails to start properly. To ensure normal operation of a Volvo generator, the first step is to accurately and timely inject well atomized diesel into the combustion chamber, and to ensure that the compressed air in the combustion chamber has a sufficiently high rotational speed and a certain temperature in the cylinder when starting the diesel engine. The ambient temperature is too low. Before starting the Volvo generator, the diesel engine should be preheated properly, otherwise it is difficult to start. The starting speed is low. For manually started diesel engines, the speed should be gradually increased, and then the pressure reducing handle should be turned to a non pressure reducing position to ensure normal compression in the cylinder. If the pressure reduc...

When the turbocharger of a diesel generator set operates at a certain speed, the airflow flow rate of its compressor is reduced to a certain extent due to certain factors. The airflow in the compressor will experience strong oscillation, causing blade vibration and surging noise at the inlet of the compressor, resulting in a significant decrease in intake pressure. This phenomenon is called compressor surge. Surging can lead to unstable operation, reduced power, and black smoke from the exhaust, and in severe cases, it can cause damage to the compressor. Fault cause: (1) Air intake blockage. The surge of the  diesel generator  compressor is mainly caused by blockage in the intake system, such as severe blockage of the air filter element, severe aging and flattening of the intake hose, and blockage of too much oil stains in the intake pipe. Due to blockage, the turbocharger delivers insufficient air to the cylinder during operation, resulting in significant fluctuations in air ...

Can you explain the precautions and methods for replacing   diesel generator   carbon brushes that heat up and turn red? Carbon brushes are usually used in DC motors to cooperate with inverters to achieve commutation, convert DC power into AC power, and drive the DC motor to rotate. Nowadays, brushless DC motors are increasingly widely used, using thyristor circuits instead of brushes to achieve commutation, thus achieving high speed, large capacity, and low noise. There are also some AC motors that use carbon brushes and conductive rings, for example, if there are windings on the rotor, how can current be supplied to the rotating rotor? Carbon brushes can be achieved through conductive rings. If the operator's generator carbon brush is severely ignited, broken, or the brush braid turns red due to heating, it may cause ring fire if not immediately addressed. The operator should immediately replace it. Let's take a look at the precautions and methods for replacement. Replacemen...

What are the reasons for insufficient power during the operation of diesel generator sets?  Diesel generator sets  have the characteristics of strong power, green environmental protection, pollution-free, and continuous operation. Occasionally, there may be insufficient power during use. So, what are the main reasons for insufficient power? Firstly, the fuel system is not smooth or the fuel injection power is insufficient. If the fuel filter enters air or becomes blocked, resulting in insufficient power, the air entering the pipeline should be removed, the diesel filter element should be cleaned, and replaced if necessary. Even if the fuel supply of the fuel injection pump is insufficient, it can also cause insufficient power. It is necessary to inspect, repair or replace accessories in a timely manner. Secondly, there is a malfunction in the cooling and lubrication system. The overheating of the diesel generator set is caused by a malfunction in the cooling or lubrication sys...

Do you know about the research on the noise generation of diesel generator sets? The exploration equipment at coal seam exploration sites usually consists of diesel generator sets, drilling rigs, slurry pumps, etc. These devices emit strong noise during operation. After on-site measurement, the noise of the diesel generator set is 98dB (A). The equipment noise not only affects the physical health of the operators, but also causes pollution to the surrounding residential environment. Control and isolate the noise of the diesel generator set. There are two types of diesel generator sets used in geological exploration, one with an output power of 250kW and the other with a power of 160kW. Due to the frequent use of the 160kW   diesel generator set , the work of this project is carried out on the 160kW diesel generator set. In addition, the original muffler structure is very simple, and its noise reduction must be strengthened. Therefore, the main measures of the project are to adopt s...
