After installing the electric actuator, the valve can be better controlled, which can not only improve work efficiency but also reduce the intensity of manual operation. Therefore, many industries are now beginning to use good quality and low price electric actuators to control valves. However, in the process of use, electric actuators are prone to torque problems, how can they be avoided?
1. Set the torque parameters correctly
When selecting the valve torque, it is necessary to ensure that the electric actuator is reliable to switch the valve, and it is also required that the torque of the electric actuator does not exceed the upper limit of the torque that the valve stem can withstand, so there are certain difficulties in parameter setting. If the torque parameter is not set If it is correct, it is prone to torque problems, such as AC power tripping, severe wear of the worm gear, bending and deformation of the door rod, and even twisting of the connecting screw between the electric actuator and the valve, and so on. In order to avoid this situation, when setting the torque parameter, the smaller torque protection value should be set first. If the torque protection is activated, the torque protection parameter setting should be increased appropriately until the valve can open and close normally in the cold state. .
2. Check regularly
In the case of light manual operation of the electric actuator, if the over-torque protection action occurs, if it is not caused by the torque protection value being set too small, it may be caused by a problem with the main board or the torque detection device. If the electric actuator is turned in the opposite direction, check that the torque switch should be disconnected, and the over-torque signal in the original direction should disappear. In order to avoid torque problems due to abnormal components, all aspects of the inspection should be done during normal use.
If the electric actuator has torque problems, it cannot operate normally. Therefore, when using a full-featured and high-quality electric actuator, the torque parameters should be set correctly according to the specific situation. It is necessary to continuously debug in accordance with a certain method, and do not blindly set it to cause torque protection action.
