Analysis of the difference between self-priming pump and centrifugal pump

Self-priming pump and centrifugal pump What is the difference? Although the self-priming pump is also a centrifugal pump, but the self-priming pump and centrifugal pump are still different. As both self-priming pumps and centrifugal pumps are based on the centrifugal force of the pump to achieve the pumping function, it also makes the user often on the self-priming pump and centrifugal pump the existence of the difference between the two pumps have confused, in fact, both The biggest difference is that the self-priming pump is not necessary irrigation water, the following small series from the self-priming pump and centrifugal pump start-up, installation and operation of the three aspects to describe the self-priming pump and centrifugal pump these two kinds of pumps Difference. The picture shows a self-priming pump, at the start, the self-priming pump for the first time starting to inject a certain amount of start-up circulating water to the pump body, follow-up start no longer need to continue to inject water into the self-priming pump body; and centrifugal Each time the pump is started, the centrifugal pump must be filled with water in the water inlet pipe and the pump body at the same time, or the auxiliary pipe should be sucked into the water inlet pipe. Second, on the device, the self-priming pump only installs the filter without the bottom valve at the lower end of the inlet pipe; and the centrifugal pump must have the bottom valve at the inlet of the inlet pipe or equipped with the exhaust device at the outlet. Third, the operation of the operation, the same performance parameters of the self-priming pump and centrifugal pump, the general self-priming pump than the low efficiency of the centrifugal pump, cavitation performance is poor. The above is the difference between the two pumps of self-priming pump and centrifugal pump, I hope your understanding and learning of water pump help.
