Common faults of electric plug valves include the following:
1. The electric plug valve cannot be opened or closed:
The cause of this failure may be power failure, motor damage, actuator failure, etc. It is necessary to check whether the power supply voltage is normal, whether the motor is running, whether the actuator is stuck, etc., and repair or replace it accordingly after confirming the problem.
2. The electric plug valve switch is not sensitive:
This problem may be due to the wear and tear of the parts in the actuator due to long-term use, causing the plug valve to switch insensitively. At this time, it is necessary to clean the parts within the actuator or replace damaged parts.
3. Electric plug valve leaks:
This failure may be caused by the sealing ring being aged, loose or damaged. It is necessary to check whether the sealing ring is intact, whether there are cracks, and whether it is loose. If there is any problem, it needs to be replaced in time.
4. Electric plug valve motor overheats:
This fault may be caused by excessive load on the motor or damage to the motor. It is necessary to check whether the motor load is too large and whether there is any abnormal noise. If necessary, replace the motor.
Method of exclusion:
1. Check whether the power supply is powered on, whether the power supply is normal, and whether the power supply is stable.
2. Check whether the motor is damaged, whether it is running normally, and whether the motor circuit is connected.
3. Clean the parts inside the actuator and replace damaged parts.
4. Check whether the sealing ring is intact, whether there are cracks, and whether it is loose. If there is any problem, replace it in time.
5. Check whether the motor load is too large and whether there is any abnormal noise. If necessary, replace the motor.
6. According to the specific fault situation, select the corresponding maintenance method to repair or replace.
