The outlet pressure of the pump is 0.05 MPa, and the range of the pressure gauge is 0–1.6 MPa. The pointer of the pressure gauge does not move, but it moves when the drain valve is opened. What’s going on?
Where should the pressure gauge be connected? Between the pump outlet and the valve?
It seems the pump outlet pressure was entered incorrectly; an extra zero was added
Firstly, the gauge range was set too high; it’s possible that the pressure at the pump outlet is relatively stable, and with a large gauge range the pointer movement isn’t noticeable. It is recommended to use a range of 0.1 or 0.16 MPa, and then observe again
When the range is large and the valve is opened, there is an instantaneous change, which triggers a reaction; but I guess it’s just a slight movement, like something coming back to life
It can’t be the pressure gauge fluctuations caused by the system connected to the waste discharge valve, right?
The range of the pressure gauge is too large; it is recommended to use a smaller shock-resistant pressure gauge
The range of 1/3 to 2/3 of the pressure gauge’s scale is the operating pressure.
The pressure gauge was chosen to be too large, resulting in a lower accuracy grade. Appropriate device parameters should be selected
Why is the outlet pressure of this pump so low? Try using a gauge with a smaller range
