Wear of rotary vane vacuum pumps in China is a common failure mode of vacuum pump parts. One is the friction and wear of the contact surfaces between parts under lubricated conditions, which often occurs in gears, cylinder blocks, vanes, rotor sliding bearings, and rolling bearings. . This kind of wear speed is slow, and the wear failure is mainly related to lubrication and sealing conditions.

　　Fatigue is a failure mechanism, and cracking is a failure mode. They often end up causing breakage of the part. This fatigue fracture failure process generally exists in gear teeth subjected to alternating loads. Commonly found in connecting bolts, anchor bolts, springs and other parts, but also in important parts such as gear transmission shafts. There are many factors involved in fatigue fracture, and specific analysis is needed for the failed parts.

　　Deformation of Chinese rotary vane vacuum pump is also a common failure mode of vacuum pump parts. Because the pump will generate a certain high temperature when it runs at high speed. Such as shells, plates, etc. are often in a heated state, the most likely to occur. The gradual plastic deformation cannot restore the original geometric size and shape of the parts, and will cause equipment failure in severe cases. Such as sealing rings, oil seals, etc.

　　Chinese rotary vane vacuum pump corrosion is another mode of vacuum pump parts failure. Commonly used in vacuum pumps operating under complex PCB, chemical and other working conditions.

　　Analysis of China Rotary Vane Vacuum Pump The above accessories are all consumable materials of the rotary vane vacuum pump. If the above situation occurs, the accessories need to be replaced. China Rotary Vane Vacuum Pump recommends that when the vacuum pump fails, we should investigate and deal with it, and make corresponding solutions to the above problems after confirming that its accessories fail.
