Witryna2 sty 2024 · IMPELLER1. Impeller serves to convert mechanical energy of the pump into velocity energy of fluid which is pumped continuously2. The liquid gets the centrifugal force by the rotation of impeller and the liquid from the suction eye continually thrown to the periphery of the impeller. WitrynaAs it was mentioned before, cavitation occurs in the low-pressure regions of the pump which is the eye of the impeller. At the suction of the pump the pressure of liquid is at its lowest. WitrynaAn impeller is usually a short cylinder with an open inlet (called an eye) to accept incoming fluid, vanes to push the fluid radially, and a splined, keyed, or threaded bore to accept a drive shaft.

Witryna26 wrz 2010 · Cavitation damage observed on the pressure side of the inlet vanes near the eye of the impeller is a sign of suction recirculation. In discharge recirculation, fluid exiting the pump discharge nozzle or the impeller discharge side at low rates may be reversed, resulting in high velocity vortexes in between the two directions of flow.
