Shenyang screw air compressor factory introduction screw air compressor working environment too dirty, sludge impurities and other contact with the lip of the shaft seal formed shaft seal wear quickly.
2 return oil is not free. Most parts of the machine head shaft sealing chamber to the suction chamber have oil return hole and oil return one-way valve composed of fluorine rubber ball, when the machine head normal work due to the suction chamber is negative pressure, through the oil return hole and oil return one-way valve inside the shaft seal excess oil back into the machine, and when the suction chamber is positive pressure, the one-way valve so that the oil and gas in the machine will not affect the shaft seal. So as a result of oil dirty or impurity carbon infarct back to the oil channel, back to the oil is not free and leakage. There are also individual self-repair will not be easy to notice the loss of the fluorine rubber ball or forget to install the formation of pressure in the nose through the return oil hole so that the shaft seal accept a lot of oil squeeze and leakage.
Some models have o-ring between oil seal sleeve and shaft. When assembling, the belt pulley does not press the shaft sleeve, which will cause the sleeve to rotate and the o-ring to wear and leak oil.
Spray paint on axle sleeve. Leakage due to spray paint on shaft sleeve and poor lip seal during assembly or maintenance at consumer plant.
5 too much vibration. As a result of the end of the nose input shaft, belt pulley or shaft gear poor dynamic balance caused by vibration, the formation of excessive wear and leakage of shaft seal.
6. Axial force or poor coaxiality (common in the head with gear increase), this kind of head mostly USES a coupling to input power. Due to the poor adjustment and assembly of the shaft coupling may result in the axial force and poor coaxiality will make the shaft sleeve and the lip of the shaft seal produce relative beat and wear quickly.
7 improper maintenance. When the user removes the motor head for some reason, it is necessary to pay attention not to damage the lip of the shaft seal, and the oil seal must be installed using special tooling and according to the requirements of the process (this is very important). Of course, if it is to change the oil seal, the initiative with the original factory accessories and at the same time change the shaft seal, otherwise it is difficult to reach the maintenance standard through pressure test.
Oil carbon. Due to the normal working temperature of screw type air compressor is higher, so when the use of tightening oil quality is not good or not according to the rules of time for oil change or the wrong oil (no screw type air compressor special oil) or different kinds of oil mixing may be in the long-term high temperature production carbon, forming lip wear too quickly, seal poor and leakage.
