NPSH or Net Positive Suction Head is a very important part of a pumping system. The systems NPSHAmust be higher than the pump’s NPSHRin order for proper pump performance and to eliminate the risk of cavitation, which can damage a pump in short order and shut down operations that depend ...
First, by looking at the net positive suction head required (NPSHr) curve of the pump. This is a calculation of how much absolute pressure is needed at the inlet to keep the system from cavitating. Second, calculate the NPSH available (NPSHa). This value represents the absolute...

Calculating NPSH is essential in order to prevent cavitation, improve efficiency, and ensure optimal pump performance. When selecting the most suitable pump for a particular application, it is important to make sure that the NPSHa is greater than the NPSHr to avoid cavitation. In other words, ...
aConsider reducing the NPSHR by installing a larger pump operating at a slower speed, which typically results in a larger inlet eye area that can lower the NPSHR. Albeit a more costly response, many times this can cure your cavitation woes. 正在翻译,请等待...[translate] ...

If the gas cavitation allowance (NPSHa) is insufficient, the pump may be damaged by disconnection or cavitation erosion. Therefore, we require the cavitation allowance of the device, NPSHa > essential cavitation allowance (NPSHr), NPSHa=Pa-Pv + Phs-Pis* (* or Pfs). ...
