Due to the effect of wind, the air always contains different degrees of dust and other impurities. If the amount of dust in the air is too much, it will be quite harmful to the compressor. The hazards are as follows:

1. The relatively hard sand will wear cylinders, piston rings, piston rod packing and its parts, shortening the service life of the machine;

2, dust into the cylinder and the lubricating oil is mixed, in the gas, the piston ring will be formed into a coke block, on the one hand impede the mechanical lubrication, can cause cylinder pull, pull; on the other hand in the compressor high temperature, sand and more The risk of explosion may be caused by

3, lime sand into the high machine is easy to block the gas, coolers, air lines and pneumatic machinery, resulting in compression equipment is not tight, resulting in reduced air volume;

4. Because the dust will increase the wear of the compressor, destroy the lubrication of the compressor, and affect the cooling of the gas, the final temperature of the compressed gas will increase, and the power consumption will also increase rapidly.

Therefore, before the air or other gas enters the compressor, it must go through a device equipped with a filter to prevent dust and impurities from entering the cylinder, to prevent the sharp increase in wear of the relative sliding member, and to prevent the oxidation of the lubricant.
