The best way to prevent pumps from experiencing cavitation is to increase the pressure upstream from the pump’s impeller. This pressure is known as the net positive suction head (NPSH). AnAnsys EnSightvisualization of oil volume in a gerotor pump shows the extent of cavitation (red) on the...

The cuve of shaft power is smooth, so the condition of excess the rated power in operation doesn't result from working operation deviation.Favorable NPSH condition.Space-saving, simply suction channel.Reasonable construction, convenient for assembling and dismantling, easy for mainte...
In summary: NPSHa = +/- static head/lift – friction loss + temperature advantage So, if there is enough static head available when pumping hot water, will the pump be OK? If static pressure in the system is high enough, yes. When the pressure falls as the water interacts w...
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...
Pumps:Locate pumps close to the suction source consideringNPSH requirements. Pumps & driver axis should be located perpendicular to the pipe rack or other equipment to minimize fire exposure in case of pump seal failure. Gas compressor or Expanders:Gas compressors should be located downwind of the...

aTraditionally the NPSH required is expressed by Eq. (2) in which the coefficient 5L c represents the acceleration of the fluid and inlet losses, while ;L w is the blade coefficient describing the low pressure zone around the blade leading edge, Fig. 1. 需要的NPSH由Eq传统上表达。 (2)系...
