What is corrosion-resistant centrifugal pump cavitation phenomenon? Cavitation corrosion-resistant centrifugal pump is a liquid at a certain temperature, for some reason the pressure at the inlet of the pump is lower than the liquid vaporization pressure at this temperature (ie, saturated vapor pressure), the liquid begins to vaporize and produce bubbles, And with the flow into the high-pressure zone, the bubble burst, the surrounding liquid quickly filled the original bubble cavitation, resulting in a hydraulic impact. This bubble generation, development and rupture now arise. How to prevent cavitation corrosion-resistant centrifugal pump phenomenon? Corrosion-resistant centrifugal pumps prevent cavitation by the following methods: 1. Cavitation can not occur while the centrifugal pump is operating, so NPSHa (NPSHr) must be guaranteed> S (Chemical Industry Pump 0.5m). When NPSHa can not meet the requirements, the buyer can try to improve the NPSHa value, or seller to reduce the NPSHr value to be resolved. 2, to reduce the loss of suction hc, for which you can try to increase the diameter, minimize the pipe length, elbows and accessories, etc .; 3, to prevent a long run at a large flow rate; 4, at the same speed and flow, Double suction pump, due to reduce the inlet flow rate, the pump is not prone to cavitation; 5, pump cavitation, the flow should be reduced or reduced speed operation; 6, pump suction pump cavitation have a significant impact; In the above method, the surface roughness of the runner is reduced, the runner is polished and cleaned, the inlet diameter of the impeller is increased to reduce the inlet flow rate, the pump speed is reduced, and the inducer is added at the pump inlet to avoid Centrifugal pump cavitation phenomenon. Improve pump efficiency. I hope the above method is helpful to you!
