How to improve the self-priming time of the pump?

The high-suction self-priming pump relies on the high-speed rotation of the impeller to produce a low-pressure area in the self-priming pump, so the self-priming centrifugal pump must ensure that the inlet pipe does not leak, that is, the external air can not enter the inlet pipe. Otherwise, it will not only affect the efficiency of the pump, but also produce serious vibration and noise during the pump operation. In the work, if the water pump is insufficient or not, we should first consider whether the intake pipe has air entry due to trachoma, cracks or loose joints, and observe it in order to find out the air intake.

The pump completely solves the problems of large axial pulling force, long self-priming time and low efficiency of the high suction self-priming pump, and has the advantages of high suction distance, short self-priming time, high use efficiency, remarkable energy saving effect, smooth operation, long service life and so on.

1. The discharge valve must be opened to start.
The gas in the suction pipe of the self-priming pump must be pumped away after starting by the self-priming pump, so the valve must be opened so that the gas can be discharged from the discharge outlet.

2. There should be enough liquid in the cavity of the high suction self-priming pump.
If there is no liquid in the cavity of the self-priming centrifugal pump, the gas-liquid foam mixture can not be formed and can not be pumped. There is too little in the cavity of the self-priming pump to pump air.
