How is the pressure of the container connected to the pump determined?
Thread Content
A clean water pump with a head of 40 meters is connected to Device A, which in turn is connected to Device B; Device B discharges the material to an atmospheric pressure environment. So, to what level do the pressures of devices A and B need to be raised to be sufficient? I would appreciate some advice from the experts here.
Since B affects atmospheric emissions and is connected to A, normal pressure can be assumed for both AB
That Container A is placed on the ground, with no height difference from the pump. There is only a 5-meter height difference between container B and container A.
It can be calculated based on the pressure drop; the discharge point is at atmospheric pressure, and the pressure drops at various points further upstream can then be determined.
Check if your Device B has a shut-off valve connecting it to the atmospheric pressure environment; if not, it is an atmospheric pressure device. The same applies to A, but there must be a shut-off valve after A; if the system does not have a safety valve, then the design pressure for A is the closing head of the pump. If there is a shut-off valve after B, it is the same as in A’s case.
