Description

Technical Field

[0002] At present, diesel generator sets are power supply equipment that uses diesel engines as prime movers to drive synchronous generators to generate electricity. Diesel, as the fuel of diesel engines in diesel generator sets, must meet the requirements of diesel engines for fuel. Due to the presence of high-precision components in the fuel system of diesel engines, the cleanliness of diesel is very high. Diesel is not allowed to be mixed with granular impurities. Once the impurities mixed in the diesel enter these precision parts, the wear of the parts will be accelerated at the least, and the sliding surfaces of the parts will be pulled or bitten at the worst. Therefore, before the diesel enters the high-pressure oil pump, the diesel must be filtered to filter out possible impurities and particulate matter in the diesel to avoid damaging these precision parts. Referring to related equipment, diesel is generally filtered only by filter element, and the filtering effect is not good. At the same time, after the filter device has been used for a period of time, the filter device needs to be replaced as a whole.
