Centrifugal pump 2 A centrifugal pump uses a spinning "impeller," which normally has backward-swept blades that directly push water outward. To arrive by a simpler method than that just given at a general idea of the mode of action of the exterior whirlpool in improving the efficiency of the centrifugal pump, it is only necessary to

A centrifugal pump is the key part of the automotive cooling system that keep circulates the coolant through the system and takes away the excess heat generated by combustion of fuel inside the engine cylinder. In the centrifugal pump impeller is the key part which circulate the coolant through thorough the pump.

The key component of a centrifugal pump is an impeller. It is connected to a motor through a drive shaft and rotated at high speed. The fluid enters the pump housing along the rotating impeller which provides centrifugal acceleration to the liquid. The fluid flows radially outward through the pump casing, from

hydraulic performances of the centrifugal pump [17–19]. The selection of blade wrap angle and blade exit angle mainly depend on the specific speed of the centrifugal pump and the actual optimized design experience. If the blade wrap angle is too large, the impeller friction area becomes large, which is bad for the improvement of efficiency.

Often a centrifugal pump is equipped with a radial vaned diffuser of the type illustrated in Figure 6. The flow exits the impeller and proceeds through the vaned diffuser before entering the volute.

When a centrifugal pump is operating, the pumped fluid exerts a force on its impeller both radially (perpendicular to the shaft) and axially (parallel to the shaft). When the pump is operating at its design point (BEP), relatively uniform pressures act upon most of the impeller's surfaces. An exception is the area about

several areas. Cavitation is primarily due to poor pump system design and a lack of awareness about how cavitation is caused. 1.2.1 CAVITATION Cavitation can have a serious negative impact on pump operation and lifespan. It can affect many aspects of a pump, but it is often the pump impeller that is most severely impacted.

Impeller is the only rotating part of a pump transfer-ring the supplied energy to the working uid. Figure 1 presents the meridional view of a centrifugal pump.

Figure 5 Radial Flow Pump Axial Flow Pumps Mixed Flow Impeller Radial flow pumps are the most common and we will focus on them in this training. Changing From Motion to Pressure Inside The Pump In radial flow centrifugal pumps, liquid enters the pump at the suction nozzle and flows into the eye of the rotating impeller.

suction head determines the Net Positive Suction Head Available to the Pump (NPSHA). The pumps in the Type B group are designed with an axial flow impeller that builds up a positive pressure of about 5 psig (34.4 kPa) (eleven feet of head) directly into the centrifugal impeller thus guaranteeing low NPSH pump requirements.
