Can’t maintain pressure – how to solve it
Thread Content
I can’t maintain the pressure; I hope experts can give me some advice
What exactly to do? Please explain clearly.
This is the control valve of a single-column press; it fails to maintain the pressure – once it reaches 15 units of pressure, it drops immediately
Are there any leakage points? What is the sealing structure?
Next, grind this type of valve; ideally, there should be no leakage
1. Leakage – try using colored water or low-pressure air. 2. The device is too small; a pipe can be connected to it in order to increase the volume and reduce fluctuations. 3. Gas needs to be released during pressure testing. 4. Temperature has an impact, as does the thermal expansion and contraction of water due to weather conditions
