Reasons And Elimination Methods Of Oil Leakage Of Gear Motor Oil Seal
Reasons and Elimination Methods of Oil Leakage of Gear Motor oil seal
Produce oil seal oil leakage reasons, first, the pressure of the drain pipe is high, the second is the motor shaft oil seal damage.
Method of exclusion:
A, drain pipe to separate the tubing, rather than share the motor return line.
B, leakage pipe access due to dirt clogging or design is too small, to try to make the oil piping fluid flow back to the tank.
C, oil seal broken, to be replaced. And check the motor shaft strain, according to the situation grinding repair, to avoid once again hurt the oil seal.
Oil commonly used materials are: nitrile rubber, fluorine rubber, silicone rubber, acrylic rubber, polyurethane, polytetrafluoroethylene and so on. When selecting the oil seal material, the compatibility of the material with respect to the working medium, the adaptability to the operating temperature range, and the ability of the lip to rotate at high speed for the rotating shaft must be taken into account. General oil seal work when the lip temperature is higher than the working medium temperature 20 ~ 50 ℃, in the choice of oil seal material should be noted. For details, please refer to: Rubber types and characteristics. The working range of the oil seal is related to the material used for the oil seal: the material is -40 to 120 ° C for the NBR, 4100 ° C to 180 ° C, and 55 ° C to 300 ° C for fluorocarbon (FPM).
