How To Maintain The Air Filter Of Diesel Generator Set

Aug. 14, 2023

A large amount of air shall be sucked into the diesel generator set during operation. The air filter is installed in front of the carburetor or intake pipe to filter out dust and sand particles in the air and ensure sufficient and clean air in the cylinder. If the air is not filtered, the suspended dust in the air is sucked into the cylinder, which will accelerate the wear of the piston group and cylinder. If large particles enter between the piston and the cylinder in a dry and sandy working environment, it will also cause serious "cylinder pulling" of the diesel generator set. Therefore, Guangxi Dingbo Power Equipment Manufacturing Co., Ltd. reminds users that they should pay attention to the maintenance of the air filter of the diesel generator set when using the diesel generator set. How to maintain the air filter of diesel generator set?

In addition to carefully maintaining the air filter of diesel generator set according to the specified time and operation requirements in the operation manual, the following points should also be noted:


1. The guide grid plate of the air filter shall be free from deformation and corrosion, and its inclination angle shall be 30~45 °. If it is too small, the resistance will increase, which will affect the air intake. If it is too large, the air flow rotation will weaken, and the dust separation ability will decrease. The blade surface shall not be painted off to prevent oxidation particles from entering the cylinder. The direction of the dust outlet shall be subject to the dust particles that can be discharged.


2. Clean the ventilation mesh during maintenance. If there is a dust collecting cup, the dust particles shall not exceed 1/3 of the height, otherwise they shall be removed in time. The mouth of the dust collecting cup shall be sealed tightly, and the rubber sealing strip shall not be damaged or lost.


3. The oil level of the fine filter shall conform to the standard. If it is too high, the oil will enter the cylinder and deposit carbon. If it is too low, the filtering effect will be reduced and the wear will be accelerated.


4. If the metal mesh in the fine filter is used as a substitute, the hole or wire diameter can only be slightly smaller and cannot be increased, and the filling amount cannot be reduced, otherwise the filtering effect will be reduced.


5. The air inlet pipeline shall be free of air leakage, and the oil change and cleaning shall be carried out in a place free of wind and dust. High pressure air shall be used to blow the filter screen in an environment with low humidity, and the blowing direction shall be opposite to the direction of air entering the filter screen. During installation, the folding directions of adjacent filter screens shall cross each other.


6. During the installation of air filter, it is not allowed to omit, reverse or wrongly install each sealing washer and rubber connecting pipe, and the tightness of each embedded position shall be ensured. The paper dust collecting cup air filter used shall be cleaned once every 50-100 hours of operation. The surface dust can be brushed off with a soft bristle brush. If the working time exceeds 500 hours or the filter is damaged, it shall be replaced in time.


The air filter of the diesel generator set plays an important role in the unit. Users should pay attention to the maintenance of the air filter when using the diesel generator set, so that the unit can keep in good operating condition and prolong the service life of the diesel engine set.
