The air filter is an important part of the diesel generator air intake and exhaust system. It can filter out dust and impurities in the air entering the diesel generator, thereby ensuring the cleanliness of the air in the cylinder and reducing the wear between the cylinder and the piston, the piston group itself, and the valve group parts. The air filter is a very important component that is easily overlooked by users. Many users do not know when to replace it. Often, after the generator set fails, they find that it is caused by not replacing the aging air filter in time.
After a certain period of use, the air filter of the diesel generator air filter will become dirty, and the air intake resistance of the air filter will also increase. When the diesel engine power is reduced or black smoke, high exhaust temperature, and difficult to start, the air filter should be checked. When the air filter is used for 150~200 hours, it should be shut down for regular inspection, maintenance or replacement.
The maintenance method of the diesel generator air filter is as follows:
Loosen the end cover nut, remove the end cover, take out the filter element and place it on a clean ground and tap it lightly or use a brush to remove dust, then use compressed air (pressure not more than 588kPa) to back-blow from the inside to the outside for maintenance. It is strictly forbidden to use oil or water to clean the filter element.
The air filter element should be carefully checked after maintenance. Method: Put a light on the inside of the filter element for inspection. If defects such as filter paper damage, end cover degumming, or after 5 to 6 times of normal use and maintenance are found, please replace the filter element.
Note: After the air filter element is maintained, pay attention to correct installation and do not miss any parts.
It is also worth noting that if the diesel generator set often works in harsh environments such as deserts and construction sites, then the user should appropriately shorten its maintenance and replacement cycle. In a dry and sandy environment, it is easy for larger particles to enter between the piston and the cylinder, causing the diesel generator set to cause serious "cylinder pulling" phenomenon, affecting the service life of the diesel generator set.
