Screw air compressor in daily use, there will be a variety of faults, some faults directly in the oil core, such as exhaust high oil, oil core pressure is too large, the oil core burst, the oil core burned Wait. The use of inferior oil core is one of the causes of these phenomena, then what other causes of failure?
First, the reason for the high oil content of the gas discharged
1, Air oil separation tank design or selection is not reasonable.
2, Excessive amount of fuel or high oil temperature.
3, Large gas consumption, use of antihypertensive overload or low pressure use.
4, Back to the oil system blocked.
5, The oil return check valve damage.
6, Back to the oil pipeline installation is not in place.
7, The minimum pressure valve failure.
8, The use of unqualified oil.
9, Using a non-matching air oil separator.
Second, the oil separator pressure is too large causes
1,The oil pressure sensor failure or inaccurate gauge damage.
2, Air compressor ambient environment, air pollutants and more.
3, Air filter, oil filter or oil of poor quality.
4, A long time without changing the oil, dirty oil.
5, The air filter and the inlet pipe between the bad seal.
6, The machine operating temperature is low, water vapor can not be discharged in time, too much water vapor leads to increased oil core resistance.
7,Air oil separator placed too long to filter damp.
8, The use of mismatched oil and gas separation core or inferior oil and gas separation core.
Third, the air oil separator burst reason
1, An incorrect boot sequence.
2, The air oil separator pressure is too large, exceeding the capacity of the support mesh.
3, The minimum pressure valve failure.
4, There are pressure pulses in the machine running.
5, oil tank design is not reasonable.
Fourth, oil and gas separator burned reason
1, The oil system failure, the main engine instant lack of oil produced by the high temperature lit air oil separator filter paper.
Initial pressure difference<0.02MPa
Residual oil amount<3PPM
