Reasons for high temperature of electric butterfly valve and its treatment

1. The temperature of the electric butterfly valve increases significantly because the motor runs for a long time and cannot effectively dissipate heat. Therefore, when we find that the motor temperature is too high, we must first use an electric pen to test whether the motor has current. If there is current, it means that the motor is running, which is why the motor gets hot.

2. Carefully analyze the reasons why the motor cannot stop working. Electric butterfly valves usually have both mechanical and electronic restrictions. Normally, the electronic stopper will lock the main position first. Mechanical limits play a supporting role.

3. Determine whether there are other debris in the pipeline, whether the butterfly valve is not a full-circulation sealing structure, and the valve plate is still in the pipeline when the valve is fully opened. If there are weeds in the medium, wooden sticks etc. block the valve plate. If the valve cannot be moved to the fully open position, the electronic stopper will not be able to stop the motor, which will cause the motor to heat up.

4. If it is determined that there are no impurities in the medium, it is probably caused by the mismatch between the mechanical limit and the electronic limit. Usually, after the motor stops working under the interference of the electronic limit, there is still a certain distance between the motor and the mechanical limit. If the electronic limit fails, the valve will be stuck in the mechanical limit, which will also cause the motor to work continuously. Cause fever. At this time, it is necessary to open the cover to check whether the stopper of the micro switch responsible for the electronic limit slips out or deviates from the original debugging position. Adjust it to the normal position to solve the problem.

5. The last reason is that the torque of the electric actuator is too small, which causes the motor to overload. This requires a larger torque motor to solve this problem. The above is the cause analysis of the heating phenomenon of the electric actuator of the electric flange butterfly valve.

The above is for you to introduce the reasons for the high temperature of the electric butterfly valve and the content of the treatment. If you still don't know about it, please come to consult our website, and we will have a professional person to explain it for you.
