Vacuum pump cavitation how to do? Vacuum pump cavitation prevention methods

Pump in the cavitation state short time work, will cause the pump noise, vibration becomes larger, and even cause damage to the pump, and therefore should prevent the water ring vacuum pump in cavitation operation. So, what are the measures to prevent the vacuum pump cavitation? Cavitation cavitation how to do? Vacuum pump cavitation prevention methods Vacuum pump cavitation prevention methods 1, increase the heat of water. Because the vacuum pump freezing water temperature will lead to a significant increase in its pumping can lead to cavitation erosion of the vacuum pump impeller. Thus raising the heat of the water to prevent cavitation motivation. 2, popularization and selection of the correctness. The vacuum pump to run in the insurance area, that is to prevent the vacuum pump in the critical vacuum or critical exhaust pressure of the sea operation, heavy volume increased cavitation. 3, the device cavitation shield tube. That can greatly increase the hazards of the pump on the pump and increase the noise and vibration caused by cavitation. 4, with the atmosphere jet. Because the atmospheric ejector is designed to prevent cavitation of the vacuum pump and cover the vacuum pump, a vacuum pump normally equipped with an atmospheric ejector is preferable in that the vacuum formed by the suction is better than that not provided. 5, to adopt lower saturated steam liquid as working fluid. The operating fluid from the original water to transformer oil, the ultimate vacuum oil saturation vapor pressure lower lower high promotion. The use of organic solvents as a working fluid, should pay attention to whether the explosion-proof motor, the vacuum pump and seal erosion problems. 6, the pump impeller, disc, etc. to adopt a strong anti-cavitation information. Non-metallic and non-metallic alloys (including Stainless Steel) compared to the number of steps, non-metallic coatings in the form of economy, but should be mastered in its operating procedures to prevent coating shedding. Adoption of alloy powder welding motivation but high profits, and some central may no longer continue. Vacuum pump cavitation is a common failure of the vacuum pump, any vacuum pump will produce cavitation. In the daily life of the Central vacuum pump, doing a good job of the fundamental protection of facilities, the vacuum pump cavitation has a vague awareness, and proper selection of steps to prevent cavitation, will certainly be able to achieve the goal of aggravating the cavitation of the vacuum pump.
