The wearing parts of diesel generator sets include three kinds of filters: air filter, oil filter and fuel filter. To extend the service life of diesel generator set, it is necessary to strengthen air filtration during use. The maintenance of the three filters, the oil filter, and the fuel filter, give full play to their role. When installing the air filter, do not miss, reverse or wrongly install the sealing gaskets and rubber connecting pipes, and ensure the tightness of each press. The paper dust cup air filter must be cleaned every 50-100 hours of work. The surface dust can be removed with a soft brush. If the working time exceeds 500 hours or is damaged, it should be replaced in time. When using an oil-bath air filter, clean the filter element with clean diesel and replace the oil in it every 100-200 hours of work. If the filter element is broken, it needs to be replaced immediately, and pay attention to adding oil as required during use.

The various fuel filters in the fuel supply system should be cleaned of debris once every 100-200 hours of work, and the fuel tank and various fuel pipelines should be thoroughly cleaned. When cleaning the filter element and seals, you should be especially careful. If you find any damage, you need to replace it in time. When changing the oil during the seasonal transition, the parts of the entire fuel supply system should be cleaned. The diesel used should meet seasonal requirements and undergo a 48-hour precipitation purification treatment.

If the oil filter is not maintained in time when the diesel generator is in use, the filter element will be blocked, the oil pressure will increase, the safety valve will open, and the lubricating oil will flow directly into the main oil passage, which will aggravate the wear of the lubricating surface and affect the service life of the diesel generator. Therefore, the oil filter must be cleaned every 180-200 hours of work. If it is damaged, it should be replaced immediately to prevent impurities from entering the lubricating surface. When the diesel generator sets are used in seasons, the crankcase and the lubricated surfaces should also be cleaned. The method is to mix engine oil, kerosene and diesel as washing oil. After the engine oil is discharged, the washing oil can be added for cleaning. Then, the diesel generator runs at low speed for 3-5 Minutes, then drain the washing oil and add new oil.
