Press the gas supply fails

Air compressor failures are: non-return valve is damaged, badly worn piston rings , inlet valve is damaged and air filter blockage.
To determine whether the non-return valve damage , just ten seconds after the compressor automatically shut down , turn off the power , the hand plate moving large belt wheel , if can more easily turn a week , Concrete mixing plants valve is not damaged ; the contrary, non-return valve is damaged; Further, the pressure switch from automatic exhaust vent below the case to be judged , in general , after the air compressor should be shut down automatically after about ten seconds to stop the exhaust , If you have been in the exhaust until the compressor starts again when to stop , precast concrete plant valve is damaged, must be replaced .
When the pressure of the air compressor oil rises slowly and accompanied by string phenomenon that has been severely worn piston ring compressor , should be replaced.
