Answer: There is only a rough distinction between the minor repair, medium repair and major repair of an air compressor, and there is no absolute boundary. In addition, the specific conditions of each user unit are also different, so the division is different. The general minor repair content is to eliminate individual defects of the compressor and replace individual parts, including:
① Check the carbon deposits on the rotor at the inlet;
② Check the diaphragm of the intake valve servo cylinder;
③ Check and tighten the screws of various parts;
④ Clean the air filter;
⑤ Eliminate leakage and oil seepage in the air compressor and pipeline;
⑥ Clean the cooler and replace the faulty valve;
⑦ Check the safety valve and pressure gauge, etc.
