Why does the water gas booster pump exhaust before each pressure?
The water booster pump generally adopts centrifugal pump.
Working principle of centrifugal pump: because the pump shell with continuous rotation of impeller is full of water, the water between the impeller blades makes centrifugal movement under the action of centrifugal force, and rushes to the housing with a certain speed and pressure, and flows into the housing where the water outlet pipeline pump passes through the flow channel; at the same time, the center part of the impeller forms a vacuum. Under the action of atmospheric pressure, water flows into the center of impeller from the suction pipe and fills the vacuum area. The water flows through the center part of the impeller and the centrifugal force, and enters the outlet pipe of the pump through the shell. In this way, as long as the suction pipeline can adhere to the water compensation and the continuous rotation of the impeller, the transmission process of the pump is completed.
Therefore, the booster pump should be pressurized to discharge air before each water inlet, so that the water can enter the pump and make the impeller overflow.
The convenient solution is to find a way to stop the pump. The pump still insists that water and air do not enter. The more useful way is to install the valve at the bottom.
