Centrifugal Pumps Pumping System
Reversible equipment
Working principle
The centrifugal pumps are used to produce flow or raise pressure to a liquid. Their working principle is simple. At the heart of the system lies the impeller. It has a series of curved vanes fitted inside the shroud plates. The impeller is always immersed in the liquid. When the impeller starts to rotate, it makes the fluid surrounding it also rotate. This gives centrifugal force to the liquid particles, and it moves radially out.
Since the rotational mechanical energy is transferred to the fluid, at the discharge side of the impeller, both the pressure and kinetic energy of the liquid rise. At the suction side, the fluid is getting displaced, so a negative pressure will be induced at the eye. Such a low pressure helps to suck a fresh liquid stream into the system again, and this process continues.
Description and operation
This group consists of one single centrifugal pump. This pump receives the additive from a tank and drives it to a measuring glass. Then the pump draws the additive from the measuring glass and drives it to the concrete mixture.
The assembly has an electrically operated valve and one pressure regulator filter in order to control the flow of the additive at the entrance. At the outlet pipe this flow is controlled by a flow meter. Moreover, it’s supplied with three check valves in order to prevent the backflow.
