Maintenance of Air Filter Element The diesel used for engineering machinery always working in the badly condition that the dust content in the air is very high. So it is require high filtering efficiency of air filter elements and high sealing of the air inlet system. The insufficiency of air inlet volume will not only directly affect the output power of engine, but also result in the carbon accumulation dramatically inside the combustion chamber and air cylinder sleeve, consequently quicken the wear of piston ring and cylinder sleeve until them were damaged.
The quality of the inlet air is not good, will also result in the early wear of cylinder sleeve and piston assembly, and consequently reduce the service life of engine. Check the air inlet system Check if the hose of the air inlet system has crack, if the clamp has loosen or perforated. Tight or change component when it is necessary to ensure there has no air leakage in the air inlet system. Air filter The maximum air inlet resistance of this kind of air filter is 6.2 kPa. The maximum air inlet resistance must be checked when the supercharged diesel runs under rated full load. Clean the dusts inside the dust collection chamber every 100 hours’ operation.
Remove the main paper filter element and knock the both ends of main filter element or use the compressed air that the pressure is not over 0.5 MPa to clean it every 100 200 hours (it can be adjusted properly depends on the dust content in the workplace environment). First blow air from the interior to the exterior along the paper fold, then blow air from outside to the inside, finally blow air from inside to outside to remove the dust. Use the same method in the maintenance condition above to maintain the safety filter elements. No use the oil or water to clean the filter element is allowed. It is need to change it if the damaged filter element is found or it is hard to remove the dirt.
Conduct above maintenance every 50 100 hours’ operation in the working condition that has severe powder. The outlet end of air filter is equipped with KBZ-1 type air filter maintenance indicator. The operator should maintain the air filter when the air filter is blocked. 20-15
