To determine whether the non-return valve is damaged, simply turn off the power after the air compressor has automatically shut down for more than ten seconds and use your hand to move the large tape wheel. If you can turn it easily for a week, the non-return valve is not damaged. . On the contrary, the check valve has been damaged. In addition, it can also be judged from the exhaust condition of the exhaust port under the automatic pressure switch. Generally, after the automatic shutdown of the air compressor, the exhaust should be stopped after about ten seconds, if it has been exhausted until the air compressor. Stopping when it is started again indicates that the check valve has been damaged and must be replaced.
2. The failure of the pressure reducing valve is: the pressure is not high, or the pressure rises slowly.
Pressure adjustment is not high, often due to rupture of the pressure regulating spring or diaphragm rupture, must be replaced; pressure rises slowly, generally due to the filter plugged, should be removed for cleaning.
3, pipeline failures are: leakage at the pipe joints, hose rupture, condensation and Other condensation.
The leakage of the pipe joints and the rupture of the hose can be judged from the sound, and should be promptly repaired or replaced. If condensate water accumulates in the pipeline, it should be drained in time, which is characterized by the fact that the condensate in winter in the north is prone to freezing and blocking the gas path.
4. The faults of the compressed air treatment module (triple body) include: failure of the oil-water separator, failure of the pressure regulator valve and the oil mister.
The failure of the oil-water separator is further divided into that the filter element is clogged and damaged, and the moving parts of the discharge valve are not flexible. Clean the filter element regularly during work to remove oil and impurities from the drain.
