Pump industry suppliers to tell you: what is the working principle of self-priming pump

the working principle of self-priming pump

self-priming pump working principle is: self-priming centrifugal pump so can send the water is due to the effect of centrifugal force. before work, pump body and the inlet pipe line must be tank filled with water into vacuum state, when the fast rotating impeller blade promote water quickly spin, spin the water under the action of centrifugal force, fly away from the impeller and pump in the water, after being thrown at the center of the impeller part form the vacuum area. The original water at atmospheric pressure (water Or water pressure) Through the pipe under the action of pressure to the feed water pipe.

this cycle, you can achieve continuous pumping. It is worth mentioning here: before starting the self-priming centrifugal pump must to the water pump shell full of water, can start, otherwise will cause heat pump body, vibration, water yield reducing, cause damages to the water pump equipment accident!

there are many kinds of self-priming pump, classification of common has the following several ways of

1 in impeller suction way points: single suction type self-priming centrifugal pump double suction type self-priming centrifugal pump.

2 according to the number of impeller points: single-stage multi-stage self-priming centrifugal water pump self-priming centrifugal pump.

3 points according to the impeller structure: open type self-priming centrifugal pump impeller and half open impeller self-priming centrifugal pump enclosed self-priming centrifugal pump impeller.

4 according to the working pressure points: low pressure self-priming centrifugal pump medium pressure self-priming centrifugal water pump high pressure self-priming centrifugal pump and vertical self-priming centrifugal pump.
