Analysis on the factors affecting the efficiency of self-priming centrifugal pump

Self-priming centrifugal pump is relying on the role of centrifugal force to achieve the delivery of liquid, mainly by impeller, pump body, pump shaft, bearing, sealing ring, stuffing box of these parts, in the process of long-term use, it will also appear some large or small failures, low efficiency is self-priming centrifugal pump in the use of the process is more prone to one of the failures, the following is for you to introduce, Self-priming centrifugal pump in the use of the process of low efficiency reasons.

The fundamental reason affecting the efficiency of the self-priming centrifugal pump should be the efficiency of the pump itself; In addition, when the operating condition is lower than the rated condition of the pump, it will also cause low efficiency of the self-priming centrifugal pump, and energy consumption will increase.

The main factors affecting the low rate of self-priming centrifugal pump also include the motor efficiency, which should be the same for other types of pump products, because, in the process of use, the motor efficiency is basically unchanged, so the motor efficiency is also very important.

In addition, the factors that affect the efficiency of the suction centrifugal pump group also include mechanical efficiency, hydraulic loss, volume loss, and some of its components are caused by wear or blockage; On this issue, human factors can not be ignored, if before the pump starts, the operator does not do a good job of the preparatory work before the pump starts, then it will also lead to the occurrence of some adverse phenomena, which affects the efficiency of the self-priming centrifugal pump.
