Elite Machinery & Equipment Co.,Ltd | Updated: Jul 18, 2016

1, Cylinder failure. Inside and outside the cylinder leak, concrete mixers are generally due to installation of the piston rod eccentricity, insufficient supply of lubricating oil, sealing rings and sealing ring is worn or damaged, caused by impurities in the cylinder and piston rod has a scar. Should adjust the rod's center position, frequently check the reliability of the oil mist, removing impurities in the cylinder; when there is a scar on the piston rod, should be renewed.

2, air failure. Concrete mixing plant common air supply failure occurs mainly in air compressor, valves and pipes and compressed air treatment components and so on. Pressure is not high, often pressure regulating spring break or rupture of the diaphragm, you must update the pressure rise slowly, usually filter blocked, should be removed to clean.

3, reversing valve failure. Pilot solenoid valve inlet and outlet holes clogged with sludge and other debris, leading to lax close, active spool is jammed and circuit failure, may cause the valve to normal direction. Be cleaned pilot solenoid valve and active sludge and other impurities on the spool.
