Concrete mixer truck Compressor common faults are: check valve is damaged, badly worn piston rings, intake valves become damaged and clogged air filter and so on.

Check valve: To determine whether the non-return valve damage small Concrete mixer truckd , small concrete mixer just after ten seconds automatically shut down the air compressor, turn off the power, the hand plate moving large belt wheel, if you can more easily one revolution, then the check valve is not damaged; on the contrary, the non-return valve is damaged; in addition, also available from the exhaust case of a small concrete mixer automatic pressure switch below the exhaust port to be judged, small Concrete mixer truck Usually after the compressor should be stopped automatically shut down after about ten seconds in the exhaust gas, if you have been in the exhaust when the compressor is started again until it stops, then the small concrete mixer check valve is damaged, replace.

Piston Ring: When a small Concrete mixer truck compressor pressure rise slowly and accompanied by a string of oil phenomenon, indicating that the air compressor piston rings are badly worn and should be replaced.

Intake valve sheet: small Concrete mixer truck when the intake valve is damaged or clogged air filter also causes the air compressor pressure rise slowly (but no strings oil phenomenon). Inspection, the palm can be put onto the air filter inlet, if there is heat out the top, then the intake valve is damaged, must be replaced; if suction is small, usually caused by dirty air filters, should clean or replace the filter small  Concrete mixer truck .
