For automatic self-priming pump selection considerations

automatic self-priming pump water slow reason: because self-control self-priming pump suction piping customers found no leakage phenomenon, such as pipe fitting, flange connection, such as fast at joint connecting local have weak leakage phenomenon is self-control self-priming pump water special slow reason, after the test tube to see if there is leakage point admit and correct, device fixed pipe again, if the device has good view control self-priming pump suction pipe leak point method, is to be able to put the self-control self-priming pump drive 5 - after filled with liquid Six minutes later, stop again with ears close to flat local, listen to whether have the white of the inspiratory sound, find leak point repair.

if the pump body model do not modify the original result is modified on the basis of open impeller flow pump lift and suction will drop, because choose open impeller will drop function indexes, the model modified open impeller self-priming sewage pump self-priming time grew faster, so choose move open impeller self-priming sewage pump car completely satisfied with the suction condition of sewage, as long as can be drawn into the pump body of impurities can carry it out. If smaller led to the obstruction of outlet pipe also might as well let's add on the pump body clean-up plate easily open.

sure good medium and after suction requirements determine the flow and head, good demands in the stainless steel control self-priming pump selection requirements in mind, the stainless steel control relative centrifugal pump self-priming pump power is much lower, so for the stainless steel automatic self-priming water pump selection must remember: if the corresponding type parameter table inside the stated when the parameters of the flow head is your demand if necessary to satisfied with the corresponding flow head, advocate you choose a kind of more appropriate, because this type is not 100% in real terms to describe the parameters, because it will loss in the suction flow and head, this is a stainless steel automatic self-priming pump selection on one of the items.

in the stainless steel control needed to admit self-priming pump lift should be calculated when stainless steel automatic self-priming pump outlet pipe horizontal interval, straight height, number of elbow, ending the required pressure, and inform us the size of the outlet piping and piping material, supply the data let's ability to calculate the demand by the head.
