Multi-stage pump in series, parallel use

In order to meet the needs of the conditions, under certain conditions, the multi-stage pump in series or parallel is a commonly used method, then you know how multi-stage pump, parallel use of the specific situation? Multistage pump string, What are the precautions when working in parallel? With this question, let's take a look at the following.
1, two multi-stage pump in series when the total head of the work is less than twice the pump work alone, more than the series before the separate run of the head; colleagues in series after the flow than a pump work alone, this is because the pump After the series, although its lift doubled, but the pipeline resistance loss did not multiply, so the multi-stage pump rich head to increase the flow.
2, two multi-stage pump parallel flow is equal to the sum of the pump flow in parallel, but less than twice the parallel flow of the pump; colleagues in parallel with the head when the pump is greater than the work of a single pump head. More friction losses increase with increasing flow, which requires each pump to increase its head to overcome this increased pipeline loss.
Multi-stage pump string, parallel work Note:
1, multi-stage pump in series, can improve the head, but pay attention to more than one pump in series behind the pump pump strength.
2, centrifugal pump parallel operation can increase the flow, in the same pipeline system, the proportion of increased flow will increase with the number of parallel pump to reduce.
3, the best use of the same performance of the centrifugal pump for string, parallel.
4, whether it is in series or parallel work, a single centrifugal pump operating point should strive to fall within the efficient area.
After reading the introduction of Xiaobian above, we are not more understanding of the multi-stage pump? Multistage pump is my company's main products, welcome friends from all walks of life come to my company to buy, look forward to working with you!
