A centrifugal pump consists of:
• water wheel turning on its axis
• a dealer in the wheel axis
• A collector section increasing spiral volute called.
The liquid enters the axis of the device by the distributor and strength
the centrifugal projecting outward from the turbine. It takes great energy
kinetic energy is transformed into pressure in the manifold where the section
is increasing.
Using a diffuser (impeller fixed) at the periphery of the impeller
allows a reduction of energy loss.
Centrifugal pumps can only begin. The air
needs to be hunted previously. You can use a tank placed in
load on the pump priming to achieve this by gravity.
To avoid defuse each pump can be restarted
interesting to use a check valve at the bottom of the suction pipe
