Filter Maintenance Knowledge
Aug 31, 2018

The vulnerable parts of diesel generator set include air filter, oil filter and fuel filter. In order to prolong the service life of diesel generator set, it is necessary to strengthen the maintenance of air filter, oil filter and fuel filter and give full play to their functions. . Air filters should not be installed in a leaky, reverse or misplaced seal gaskets and rubber connection pipe, and ensure the tightness of each inlay. The use of paper dust cup air filter, each 50-100 hours of work, to remove dust once, you can use a soft brush to brush away the surface dust, if the working time is more than 500 hours or damaged, should be replaced in time. Use oil bath air filter, every 100-200 hours of work, clean diesel oil cleaning filter element, and replace the oil, if the filter element has broken, it must be replaced immediately, and pay attention to the use, according to the provisions of the oil.


Fuel filters in the fuel supply system should be cleaned once every 100-200 hours, and the tanks and pipelines should be cleaned thoroughly. When cleaning the filter elements and seals, they should be very careful and find that breakage needs to be replaced in time. During the seasonal transition, all parts of the fuel supply system should be cleaned. The diesel used should meet the seasonal requirements and need 48 hours of sedimentation and purification.


If the oil filter is not maintained in time, the filter element is blocked, the oil pressure is increased, the safety valve is opened, and the lubricating oil flows directly into the main oil passage, which will aggravate the wear of the lubricating surface and affect the service life of the diesel generator set. Therefore, the oil filter should be cleaned once every 180-200 hours and replaced immediately to prevent impurities from entering the lubricating surface. The diesel generator set should also be cleaned by mixing engine oil, kerosene and diesel oil as washing oil. The oil can be cleaned by adding washing oil after it is discharged. Then, the diesel generator runs at low speed for 3-5 minutes, then drains the washing oil and adds new engine oil.
