Sliding vane pumps have a number of free fans sliding out in and out of the grooves mounted on the rotor. If the rotor rotates, then the fans are due to centrifugal force, ga-ya spring or fluid pressure given, will push the fan out and push the stator wall. Since the rotating source of the rotor is eccentric to the stator axis, the difference between the volume of the space between the rotor and the stator occurs.
By rotating the rotor the fluid flows in to fill the space between the fan, the rotor wall and the stator. This space will gradually expand and will shrink on the expense side. Thus there is fluid removal from the inlet side to the outlet side of the water pump. The flow volume setting is done by changing the eccentric distance of the rotor axis to the stator sum. This type of pump can reach a pressure of 165 kg / cm2 at a rotation of 2500 Rpm.
According to the process of energy transfer and liquid material as flow material, centrifugal pomapa including hydraulic fluid flow machine. The process of switching power in the blade is the result of a fluid deflection. The characteristics of a centrifugal pump are determined by:
- The volume of the pumped fluid, Q
- High rise, H
- Circumstances on the suction side
- Power required pump
- Speed of play
