Do you know how to repair the screw and body of screw air compressor?

   During the maintenance of the air compressor, the screw part of the air compressor is most likely to be ignored by everyone. In fact, the screw part is also prone to failure. Since the failure of the screw part will also cause the air compressor to be out of normal use, the screw part also needs to be repaired immediately in case of failure.
   When the screw part of the air compressor is repaired, the body part of the air compressor also needs to be repaired. Because the hardness of the inner surface of the body is higher than that of the screw part, the damage of the body part is faster than that of the screw part. Then the repair method of the body part is to directly bore the air in the body, grind it to a new diameter, and then prepare a new screw according to the new diameter. However, the premise for this repair is that there is a certain nitriding layer in the body.
