This article continues to introduce the function of diesel filters in diesel generator sets. The fuel filter of a diesel generator set is mainly composed of three parts: filter element, housing, and filter seat. All models are universal, except for overflow valve 8 which has two structures. C0810A or C0810B filters are selected according to different models. A 12 cylinder V-type diesel generator set is installed in parallel with one C0810A and one C0810B. The fuel is sent from the fuel delivery pump to the fuel filter, where impurities are removed from the fuel through a paper filter element before entering the interior of the fuel filter cartridge, and then passing through the oil collection chamber on the filter seat to the fuel injection pump. The filter seat is equipped with a return joint and an overflow valve. When the fuel pressure inside the fuel filter exceeds 78kPa (0.8kgf/C ㎡), excess fuel is returned to the fuel tank through the return joint. Connec...
During the storage, transportation, and refueling process of fuel, impurities such as dust, sand, and metal shavings often mix in. If these impurities enter the precision components of the fuel system (fuel injection pump, injector) along with the fuel, it will cause increased wear and even jamming of the parts, directly affecting the normal operation of the diesel engine. Therefore, a fuel filter must be installed in the fuel supply system to eliminate various impurities in the fuel, ensure that the precision components of the fuel system are not worn or blocked, ensure the normal operation of the fuel supply system, ensure the stable operation of the diesel engine, and improve reliability. Fuel filters can be divided into two categories based on their filtering effect: coarse filters and fine filters. Generally, diesel engines connect these two types of filters in series in the fuel supply system (on the pipeline between the fuel pump and the throttle body inlet). Unlike l...
