FAQ 1: Press the operation function key, the emergency shut-off valve is in a closed state, and the machine does not operate.
Solution: ① Check whether the operation panel is powered and whether the emergency stop button is in the clamping position;
② Check whether the surface wind pressure is lower than 0.45MPa; Check whether the pressure regulating valve of the emergency shut-off valve works normally.
FAQ 2: Press the operation function key, and the emergency shut-off valve is open but does not operate.
Solution: ① Check whether the CNG inlet water pump of the machine is turned on and whether the pressure gauge is marked;
② Check whether the surface stop valve of the intelligent transmitter is open;
③ Check whether the valve position on the primary pressure regulating valve is open.
Common problem 3: the over-voltage vent pipe valve behind the primary pressure regulating valve is released.
Solution: Check whether the pressure regulating valve of the emergency shut-off valve is normal.
Common problem 4: Discharge of inlet and outlet overvoltage vent pipe valve.
Solution: ① Check whether the pressure regulating valve of the emergency shut-off valve is normal;
② Check whether the air pressure reducing valve of the regulator is cracked or hard compound such as iron pin is stuck on the gate valve.
