How to maintain the diesel engine air filter？
The engine generally needs 14kg/air for every 1kg/diesel combustion. If the dust entering the air is not filtered out, the wear of the cylinder, piston and piston ring will be greatly increased. According to the test, if the air filter is not used, the wear rate of the above-mentioned parts will be increased by 3-9 times. When the pipe or filter element of the diesel engine air filter is blocked by dust, it will lead to insufficient intake air, which will cause the diesel engine to make a dull noise when accelerating, run weakly, increase the water temperature, and the exhaust gas becomes gray and black. Improper installation, the air containing a lot of dust will not pass through the filter surface of the filter element, but will directly enter the engine cylinder from the bypass. In order to avoid the above phenomena, daily maintenance must be strengthened.
Tools/Materials:
Soft brush, air filter, equipment diesel engine
Method/step:
1. Always remove the dust accumulated in the dust bag of the coarse filter, the blades and the cyclone pipe;
2. When maintaining the paper filter element of the air filter, the dust can be removed by gently vibrating, and the dust can be removed with a soft brush along the direction of the folds. Finally, the compressed air with a pressure of 0.2~0.29Mpa is used to blow from the inside to the outside;
3. The paper filter element should not be cleaned in oil, and it is strictly forbidden to contact with water and fire;
The filter element should be replaced immediately in the following situations: (1) The diesel engine reaches the specified operating hours; (2) The inner and outer surfaces of the paper filter element are gray-black, which have been aged and deteriorated or have been infiltrated by water and oil, and the filtration performance has deteriorated; (3) The paper filter element is cracked, perforated, or the end cap is degummed.
