(1) Air compressor failure is: stop valve damage, piston ring wear serious, inlet valve piece damage and air filter blockage. To determine whether the stop valve is damaged, simply turn off the power supply after more than 10 seconds of automatic shutdown of the air compressor, use the hand plate to move the large tape wheel, if it can be more easily rotated for a week, it indicates that the stop valve is not damaged, on the contrary, the anti
Generally in the air compressor after automatic shutdown should stop the exhaust after about more than 10 seconds, if it has been in the exhaust until the air compressor start again to stop, it is indicated that the stop valve has been damaged, need to be replaced.
When the pressure of the empty press rises slowly and is accompanied by a series of oil phenomena, it indicates that the piston ring of the air compressor has been seriously worn and should be replaced in time. When the inlet valve is damaged or the air filter is clogged, it can also cause the pressure of the air compressor to rise slowly (but there is no chain oil phenomenon).
When inspecting, the palm can be placed on the air filter inlet, if there is hot gas to the outer top, it indicates that the inlet valve is damaged, must be replaced, if the suction is small, generally the air filter is dirty, should be cleaned or replaced filter.
(2) The fault of the decompression valve is: The pressure adjustment is not high, or the pressure rise is slow and so on.
Pressure adjustment is not high, often due to pressure-regulating spring fracture or diaphragm rupture caused by, must be replaced; the pressure rise slowly, generally due to the blockage of the filter, should be removed from the cleaning.
(3) Pipeline failure is: pipe joints leakage, hose rupture, condensate accumulation and so on.
Pipe joint leakage and hose rupture can be from the sound to judge the leakage of the site, should be repaired or replaced in a timely manner, if the pipeline accumulation of condensate, should be discharged in a timely manner, characterized by the northern winter condensate easy to freeze and clog the gas road.
(4) The fault of compressed air treatment assembly (triple body) is: oil-water separator fault, pressure regulating valve and oil mist malfunction. The fault of oil-water separator is divided into, such as blockage and breakage of filter cartridge, inflexible moving parts of discharge valve, etc.
Always clean the filter cartridge in the work, remove the oil and impurities in the discharge device.
The fault of the pressure regulating valve is the same as the "(2) pressure relief valve fault" above. The fault phenomenon of oil mist is: No drops of oil, water deposited at the bottom of the oil Cup, damage to the seal ring at the mouth of the oil cup, etc. When the oil mist does not drop oil, should check whether the air flow of the air inlet is lower than the fog flow, whether the leakage, oil volume adjustment needle valve is blocked, etc., if the bottom of the oil cup deposited moisture, should be removed in a timely manner, when the seal ring damage, should be replaced in a timely manner.
