Concrete mixing plant should be how to solve the gas supply fails

Concrete mixing plant air mixing equipment company failures are most often encountered problems, but how to solve it stumped a lot of people . Zhengzhou Bona company based on years of production and sale of concrete mixing station technology and experience , summed up some of the gas mixing station and analyze the causes and resolution . I hope the new and old customers for concrete mixing station maintenance help.
Concrete mixing plant air supply failure and solutions are:
( A ) air compressor failures are: non-return valve is damaged, badly worn piston rings , inlet valve is damaged and air filter blockage.
To determine the concrete batching mixing plant check valve is damaged , 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 , then the only reverse valve is not damaged; Conversely , non-return valve is damaged; Further, automatic pressure switch from an exhaust port below the discharge conditions to be judged , in general , after the air compressor should be shut down automatically after about ten seconds stop the exhaust , if you have been in the exhaust until the compressor starts again when to stop , then the check 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.
When the intake valve is damaged or clogged air filter , but also make the air compressor pressure rises slowly ( but no strings oil phenomenon ) . Checking , can be put to the palm of the air inlet filter , if the heated air out the top , then place the intake valve is damaged , must be replaced ; if suction is small , usually caused by dirty air filters , filters should be cleaned or replaced .
( 2 ) concrete mixing station valve failure are: pressure regulator is not high, or the slow pressure rise . Pressure regulator is not high, often due to pressure regulator spring break or diaphragm failure and must be renewed ; pressure rises slowly , usually caused because the filter is clogged , should be removed and washed .
( 3 ) Piping failures are: leaking pipe joints , hose rupture, condensate aggregation .
Leaking pipe joints and hose rupture up to judge the sound leak from the site , should be promptly repaired or replaced ; if there is accumulating condensate pipeline , it shall promptly drained , is characterized by condensed water in the northern winter, easy to knot ice and clogging gas .
( 4 ) Dry mix concrete batch plant air handling component failures are: oil and water separator failure , regulator and lubricator failure.
Failure of oil-water separator is divided into , filter clogging , breakage , drain valve moving parts moving parts is not flexible and so on. Work should always clean the filter , remove sewage and impurities inside the oil .
