Control of pump outlet pressure
Thread Content
The pipeline has no pressure with the pump outlet valve fully open; there is 5 kilograms of pressure before the valve when it is closed halfway. Why is there no pressure behind the valve?
What type of pump is it? What is the medium being transported?
It might be due to the pipes being too large, resulting in low pipe resistance
When the pump outlet is fully open and the flow rate exceeds the rated value, the pressure will drop. This situation is likely caused by a large pipe and a small pump.
I agree with the view from floor 345; the original poster can share the specific details of the pump and pipelines so that we can discuss them.
