What are the self-priming factors of vertical end suction pump
 Jan 02, 2022|View:123

The self-priming performance of vertical end suction pump mainly includes self-priming time and maximum self-priming height. Self-priming time is the time required for the vertical end suction pump to pump up liquid in the self-priming process. The maximum self-priming height is the maximum height of the vertical end suction pump for the liquid surface when pumping on the liquid.

By analyzing the factors affecting the self-priming performance of vertical end suction pump, it is found that.

1、Increasing the maximum circumferential speed of the impeller outlet can effectively increase the self-priming capacity of the self-priming pump, but this will affect the basic performance parameters of the pump such as flow rate and head.

2. There is a direct relationship between water storage and self-priming performance: when the water storage increases, the self-priming height of the pump increases significantly, but when the water is too large, it will slow down the process of gas discharge and increase the self-priming time. Therefore, the self-priming pump should reasonably determine the size of the water storage chamber.

3、The area of the reflux hole is related to the self-priming time and self-priming height.

4、Setting gas-liquid separation acceleration device can accelerate the gas-liquid separation, that is, it can shorten the self-priming time. Therefore, if the structure of the self-priming pump allows, a separation chamber should be set to shorten the self-priming time.


End Suction Pump


To sum up, when improving the self-priming performance of the vertical end suction pump, all factors should be taken into consideration so that the vertical end suction pump can meet the requirements of use.
