THE SUCTION ABILITY OF CENTRIFUGAL PUMPS

The flow of liquid in front of the impeller of centrifugal pumps has a circumferential velocity component. The discharge influences the prerotation ahead of the impeller. The suction ability of centrifugal pumps is influenced by the prerotation and the deviation of the entering angle of flow in front of the impeller. The mathematical expression for the calculation of the Net Positive Suction Head is included.
