How to maintain oil-free air compressor

How to properly maintain and maintain the oil-free air compressor

1. Maintenance and maintenance of air intake filter element of oil-free air compressor.

The air filter is a component that filters out air dust and dirt, and the filtered clean air enters the compression cavity of the screw rotor for compression. Because the internal clearance of the screw machine only allows particles within 15u to be filtered out. If the air filter element is blocked and damaged, a large amount of particles larger than 15u will enter the screw machine to circulate, which will not only greatly shorten the service life of the oil filter element and the oil fine separation core, but also cause a large amount of particles to directly enter the bearing cavity, accelerate the bearing wear and increase the rotor gap. The compression efficiency is reduced, and even the rotor is boring and seized.

2. Replacement of oil filter of oil-free air compressor.

After the new machine runs for 500 hours for the first time, the oil core should be replaced, and the oil filter element should be removed with a special wrench. Oil should be added before the new filter element of the oil-free air compressor is installed. The filter element seal should be screwed back to the oil filter seat with both hands and tightened firmly.

3. Maintenance and replacement of oil fine separator.

The fine oil separator is a component that separates the screw lubricating oil from the compressed air. Under normal operation, the service life of the fine oil separator is about 3000 hours, but in harsh use environments, the maintenance and replacement cycle of the air filter element must be shortened, and even consideration is given to adding Install the front air filter.

4. Maintenance and replacement of oil-free air compressor oil.

Oil-free air compressor oil has a decisive influence on the performance of oil-injected screw machine. Good oil has good oxidation stability, rapid separation, good foam cleaning, high viscosity and good corrosion resistance. Therefore, pure special screw oil must be used. The first oil replacement will be carried out after the new machine runs in for 500 hours, and the new oil will be replaced every 2000 hours after operation. Replace the oil filter at the same time when changing the oil.

In short, according to the operating procedures, regular replacement of oil-free air compressor parts and lubricating oil, cleaning of the oil system and cooler water, comprehensive recording of operating parameters, regular analysis of it, to find out the problems, timely maintenance is very necessary.
