Pneumatic actuator open and close when abnormal jitter, and slow response how to do

1. The standard supply pressure of most pneumatic actuators is 0.4-0.7MPa. First, please ensure that the air pressure of the pneumatic actuator is not too low. If the supply pressure is lower than the above phenomenon, it needs to be corrected with time.

2. Check whether the solenoid valve works normally, whether the switch is normal and whether the exhaust is smooth. In daily check, solenoid valve operation is abnormal, need to repair and replace in time, or contact the manufacturer for maintenance. The longer the delay time, the greater the loss.

How to deal with the slow response of pneumatic actuator and valve opening and closing jitter?

3. For single acting pneumatic actuators, if they are too slow or trembling, the exhaust pipe is blocked and the solenoid valve is not faulty. If the reason cannot be confirmed, the spring inside the actuator is too strong. Please check whether. Please contact the manufacturer in time to resolve the problem.

4. Check again whether the output torque of this type of actuator matches the valve body of the current device. If the additional output torque is less than the torque required by the valve body, it will slow down or vibrate. If this occurs, replace the valve or pneumatic actuator type.

Because of changes in actual operating conditions (such as aging accessories, aging parts, replacement of original valves, air supply system faults), pneumatic actuators are often used in this category. When the above changes occur, the valve pneumatic actuator fault will certainly affect the normal pipe control. Let's look at how to deal with the slow response of the pneumatic actuator and the opening and closing jitter of the valve.
