Use an air compressor to pressurize the tower, and check the pressure gauge behind the pump at the bottom of the tower to determine how much pressure has been applied. Also, verify whether the pressure gauge behind the pump is accurate
Both the design pressure and the operating pressure generally refer to the pressure at the top of the tower; there is no problem as long as it is a gas.
It probably isn’t very accurate; you can simply check the pressure at the bottom or middle of the tower
There will be errors; at least the mechanical seal leaks. It’s acceptable if the requirements aren’t very strict.
The processes are interconnected; the bottom pump and the tower form a single system. The pressure indicated by the gauge on the bottom pump is used as a reference to determine the pressure level in the system – everything is fine!
It should be accurate; there’s just a settling time.........
With a smooth process flow, and as long as there is no significant leakage from the pump seal, it should definitely work!
It can be used as a reference, but precise adjustment isn’t possible. Besides, which tower doesn’t have a pressure indicator?
