Design pressure of centrifugal pump
Thread Content
When the design pressure of a centrifugal pump is 1 Mpa, can it be said that the pump’s head is 100 m?
What is the relationship between design pressure and head? First, figure out what head is
The design institute advises you: No, centrifugal pumps are rarely specified using design pressure to indicate head; when head is mentioned, it is always the actual head value that is used. The design pressure refers to the design pressure of the shell material. It is the internal pressure that the pump can withstand.
No, the design pressure refers to the maximum pressure limit that the pump is designed to withstand; it is generally the sum of the inlet pressure and the head. Referring only to the relationship with the pump’s head without mentioning the inlet pressure is not accurate enough
The design pressure refers to the working pressure that the pump can withstand; it is related to the material and wall thickness, and it is certainly greater than the head
No, it refers to the maximum pipeline outlet pressure that his design can withstand. In fact, if the designed pressure is 1.0 MPa, we conduct pressure testing at 1.5 MPa before shipping the product as part of the testing process. I don’t know if others do it or not, but my company does.
These are two different concepts; the explanation provided above is very good
