- 9. Module-5 Introduction to Pumps Hydraulic machine which convert mechanical energy into hydraulic energy are called pumps. The Hydraulic energy is in the form of pressure energy . energy . Pumps are also called as power absorbing Machine. There are two types Centrifugal pumps Reciprocating Pumps Dr. Mohammed Imran
- 10. Working principal of a centrifugal pump The working principal of a centrifugal pump. The liquid to be pumped enters the centre of the impeller which is known as eye of the pump and discharge into the space around 1. Centrifugal pump Centrifugal pumps converts mechanical energy by means of centrifugal force acting on the fluid. Dr. Mohammed Imran pump and discharge into the space around the casing and hence filling the space. Due to the rotation of the impeller inside the pump casing a forced vortex is set up which imparts pressure head to the liquid purely by centrifugal action. The pressure head developed by centrifugal action is entirely by the velocity imparted to the liquid by rotating impeller and not due to any displacement or impact. Thus the mechanical action of the pump is to impart velocity to liquid so that its speed is enough to produce necessary centrifugal head for discharging.
