The first is the gas source fault, common failure occurs in air compressor, reducing valve, pipeline, compressed air processing components, etc.. Air compressor common fault is the check valve damage, the piston ring wear serious, air valve damage and air filter plug. Processing approach is to put the palm of the inlet to the air filter, if heat outward top, inlet valve has damaged, to be replaced; if smaller suction, is generally caused by air filter is dirty, clean or replace the filter. And the pressure is not high, often the spring break or the diaphragm rupture, must be updated; the pressure rise slowly, generally filter plug, should remove the cleaning. Pipeline failure joint leakage and hose rupture can be by voice judging gas leak site, if pipeline in the accumulation of condensation water ice and jam the gas path should be ruled out in a timely manner. Oil and water separator filter plug, damage, the movement of the valve is not flexible and so will cause failure so often clean the filter element, remove the sewage valve and other impurities.
The second is cylinder fault, such as the piston rod is provided with an eccentric, oil supply, sealing ring and a sealing ring wear or damage, cylinder with impurities and piston rod has scars will cause the cylinder leakage. The center position of the piston rod should be adjusted, and the reliability of the oil mist device should be checked regularly, and the impurity in the cylinder is removed, and the piston rod has the scar, and the new piece should be replaced when necessary.. If the piston or piston rod is stuck, lubrication, gas supply shortage, or the cylinder with condensate and impurities will cause the cylinder output force and action is not smooth. The center position of piston rod should be adjusted, the reliability of oil mist operation is checked, if the gas supply pipeline is blocked, the condensate and impurities in the cylinder should be cleared in time..
Third common is the commutation valve fault, the valve fault can not change or reverse the slow motion. At this point should replace the lubricating oil, the sliding part of the reversing valve or the replacement of the spring and reversing valve. While the spool valve sealing ring wear, valve and valve seat damage, gas leak valve, slow or normal operation can not change, should replace the sealing ring, the valve core and valve seat, when necessary replacement of the new valve.
The fourth is the concrete mixing machine failure of the gas path system, in the powder material measuring hopper discharge often feed shaft drives the cylinder to be stuck; driven by the rack cylinder turning plate butterfly valve stuck to closing is not in place or not open. So frequently clear over powder caking on the inner wall of the butterfly valve plate. Above is the summary of haomei machine pneumatic system common faults and solutions, customers such as meet can't solve the problem can contact us send technicians on-site service.
