Common problems and troubleshooting of air compressor maintenance

During the use of the air compressor, the service life, use method or improper maintenance may cause the air compressor failure, and the most direct way to solve the failure is to solve it through maintenance. There are different maintenance solutions for different failure causes of the air compressor. Then, what are the common problems in the maintenance of the air compressor?


Excessive noise during work; There may be two reasons for this failure. One is that the bearing at the inlet or exhaust end is damaged; Second, the bearing of the motor is damaged. To completely solve the problem of excessive noise, it is necessary to replace the corresponding bearing.


Compressor temperature is too high; In addition to the lack of oil in the compressor, this fault may also be caused by the blockage of the corresponding parts, mainly including: the oil filter is blocked; The surface of the oil cooler is blocked; The filter element of the oil-gas separator is blocked or the resistance is too large. When the temperature is too high due to lack of oil, it can be solved by adding oil properly; If the temperature is too high due to the blockage of the corresponding part, it needs to be removed for cleaning and can be replaced if necessary.


Air compressor maintenance


Air compressor exhaust volume is too low; The cause of this failure may be: insufficient horsepower of diesel engine or motor; The air valve spring is damaged; For air leakage of cooler or vent pipe, the main solution is to adjust the working horsepower of diesel and motor, and replace new spring plate; Tighten the loose connecting rod screws to prevent air leakage.


Low cooling efficiency of cooler; The possible reasons for this failure are: too much dirt accumulated on the cooler, affecting the heat conduction effect; The solution is to check and clean the dirt on the cooler in time to improve the cooling efficiency.


The structure of the air compressor is very complex, involving a large number of parts and components. Any small part, including a small screw, may cause air compressor failure, and there are many external causes of failure. In the maintenance of the air compressor, it is difficult for non professional maintenance personnel and testing equipment to accurately find and solve the failure. The maintenance of the air compressor requires professionals, Only professional tools and techniques can truly find and eliminate faults.
