Piston air compressor, breather valve, oil injection
Air compressor running time is too often, the summer weather is too hot, long time work or overload work will appear this phenomenon, suggest to change a larger piston machine, let the air compressor can take a rest,
As the case is, the air compressor is of poor quality. This machine may be aluminum piston, aluminum connecting rod, cylinder radiator less or small area, poor heat dissipation, the inlet and exhaust valve group seal is not good, produce high temperature. Large pressure injection in crankcase. Not suitable for long time use, such as factory recommended replacement
1. non-return valve return air2. inlet, exhaust, cutting or valve assembly problems (broken or sealed)3., cylinder head cushion leakage in the middle
