How to deal with the slow response of pneumatic actuators and valve opening and closing jitter?
Pneumatic actuators have a wide range of applications. This product is used in various working conditions. Due to changes in actual working conditions, improper use will also cause some failures, such as aging of accessories, aging of parts, and replacement of original Valves, gas supply system failures, etc., when the above changes occur, the valve pneumatic actuator failure will definitely affect the normal pipeline control. Let's take a look at how to deal with the slow response of the pneumatic actuator and the valve opening and closing vibration.
1. The standard air source pressure of most pneumatic actuators is 0.4-0.7 MPa. First of all, please make sure that the air pressure of the pneumatic actuator is not too low. If the air supply pressure is lower than the above phenomenon, it needs to be corrected over time.
2. Check whether the solenoid valve works normally, whether the switching is normal, and whether the exhaust is smooth. In the daily inspection, the solenoid valve is not working properly and needs to be repaired and replaced in time, or contact the manufacturer for maintenance. The longer the delay time, the greater the loss.
3. For single-acting pneumatic actuators, if they are too slow or trembling, the exhaust pipe is blocked and the solenoid valve is not malfunctioning. If the cause cannot be determined, the internal spring of the actuator is too strong. Please check if it is too strong. Please contact the manufacturer in time to resolve.
4. Check again whether the output torque of this type of actuator matches the valve body currently installed. If the rated output torque is less than the torque required by the valve body, it will slow down or jitter. If this happens, please replace the valve or pneumatic actuator model.
