Answer: The gauge pointer remains at the “zero” position; possible reasons for this include (clogged pressure transfer tubes and valves), (a damaged gauge), or (the gauge’s valve not being opened). ============================= ☛[Haichuan Official Account] “Daily Recommendations” activity for various sections: http://bbs.hcbbs.com/thread-1603884-1-1.html (Source: Haichuan Chemical Forum)
1. The pressure gauge is broken. 2. The pressure in the pipeline is low or non-existent. 3. There is a blockage, preventing proper display
(The valve is not open), (The valve, pressure gauge connection tube, or trap is blocked), (The pointer is loose from the central shaft or stuck)
Pressure tap is blocked, gauge is malfunctioning; no pressure or negative pressure
The valve is not open; the valve, pressure gauge connection tube, or trap is blocked; the pointer is loose from the central shaft or stuck.
The pressure gauge is broken, the needle valve is not open, and the pressure here is at atmospheric level
The valve before the pressure gauge is not open; there is no pressure, and the pressure gauge is damaged
There is no pressure inside the pipe; the pressure inside is lower than the lowest value indicated by the pressure gauge, and the pressure gauge is damaged
The pressure relief valve is not in use or is blocked; the pressure gauge is faulty, and there is no flow in the pipeline ahead of the gauge
1. No pressure. 2. The pressure range of the pressure gauge is too large. 3. The pressure is too high, causing the pointer to reach its maximum value and then stop functioning
