Diesel Generator Tech

  It has been known from the working process of the diesel engine of the generator set that the diesel fuel is injected into the cylinder and mixed with the hot air, and then ignites and burns to generate power. Therefore, the horsepower of the diesel engine is naturally related to the amount of air and the amount of diesel it can burn. In this article, Starlight Power Generation Equipment will introduce it in detail. At high altitudes, due to the decrease in atmospheric pressure, the air density decreases, and the weight of the air drawn into the cylinders of the  generator set  is correspondingly reduced, which limits the amount of diesel that can be burned, and the horsepower decreases. For the same reason, the high temperature and humidity of the air will also reduce the horsepower of the diesel engine of the generator set. Therefore, the use of diesel engines in different regions, or under different atmospheric conditions in the same region, should consider this power change. For

The fuel consumption of   diesel generator sets   is a major standard for measuring the performance of diesel generators, and it is also a factor that affects the cost of generator use. How can we effectively reduce the fuel consumption of Cummins generators? The following are the fuel-saving techniques analyzed by Starlight Power technicians for you.   1. Regularly check and maintain the Cummins generator. Carefully maintain and maintain, regularly check and adjust valve clearance, fuel injection pressure, fuel supply time, etc., and promptly eliminate scale and dirt on the cooling water jacket.   2. Remove carbon deposits in time. When the diesel generator is running, the relevant components generate high temperature during the combustion process, which causes the ash carbon polymer to adhere to the valve, valve seat, fuel injection nozzle, piston top, etc. If it is not cleaned in time, it will increase the fuel consumption and seriously affect the normal operation of the generator.

  Regarding the function of diesel generator filter, some customers have the wrong concept, thinking that the filter is optional, or it is relatively sloppy in maintenance. To sum up, we think that everyone must first clarify a concept that the filter is very important, and then pay attention to the following three maintenance aspects that are easily neglected: 1. Some users lose the upper and lower sealing rubber gaskets and oil cover of the filter element when maintaining the filter of the  diesel generator set , so that the diesel oil does not pass through the filter element and flows into the filter without resistance from the gap between the filter element and the filter cover. The inner cavity of the filter element makes the diesel filter lose its filtering and purification effect. 2. Some users reverse the positions of the trays and springs of the diesel generator set filter, or even throw them away, so that the oil inlet and outlet holes on the diesel filter cover are open, and

  Although the Volvo diesel generator injector is a small part, if it fails, the entire equipment has to be shut down. Therefore, it is necessary to maintain the Volvo diesel generator fuel injector. If the fuel injector is not cleaned for a long time, grease will be produced, which will block the fuel injection nozzle and cause poor fuel injection. First of all, when the technical workers assemble the injector, they must install the assembly standard to prevent the assembly from being in place. Be extra careful when installing the fuel injector heat shield, neither too loose nor too tight, too loose, there is a gap between the fuel injector and the heat shield, the heat insulation effect is greatly reduced, and it is easy to cause the fuel injector And the heat shield burns off. If it is too tight, the injector will feel oppressed. Under the combined action of the thermal alternating load and the high pressure load of fuel injection, the head of the injector will be broken, the needle
