On the relationship between the head of a centrifugal pump and the effective head
Thread Content
Here is a question for everyone to consider: When a centrifugal pump is operating with a constant flow rate, its head should be greater than the effective head required by the pipeline. I think the answer is: wrong. When a centrifugal pump is operating with a stable flow rate, its head should be less than the effective head required by the pipeline. Because the head does not include the inlet pressure. And the effective head includes head and inlet pressure. Please discuss whether what I said is correct What is the relationship between head and effective head? Discuss together, improve together. For basic information on pumps, please refer to the following link. http://www.cngspw.com/vbooks/ShowSubject.asp?SubjectID=6518
In my opinion, it’s not worth discussing!
Haha, please understand the concept of head carefully
The effective head refers to the static head and the dynamic head; the head height should be the effective static head, right?
A major issue here is: does the head include the inlet pressure? According to the definition of head, it should not include the inlet pressure.
The outlet pressure is the inlet pressure plus the head
