how to deal with pneumatic actuators react slowly, closing valve to start shaking? < br / >
pneumatic actuators used at the scene state often corresponding changes because of the change of actual working condition, such as attachments in aging, aging and original valve replacement of spare parts, gas supply system failures, etc. , when this change valve pneumatic actuator failures will inevitably affect the normal line control, let's take a look at how to deal with slow response, start off valve pneumatic actuators jitter problem.

一。 Most of the pneumatic actuators standard gas supply pressure of 0. 4 to 0. 7 mpa, first check whether the pneumatic actuator air pressure is too low, if you have less than the gas supply pressure phenomenon, should be timely and correct processing. < br / >
2. Check whether the electromagnetic valve is working properly, whether the switch is normal and exhaust flow, daily examination revealed electromagnetic valve is not normal for timely replacement of repair, or contact the manufacturer maintenance process, the longer delay, the greater the loss. < br / >
3. Single-acting pneumatic actuator, if an action is too slow or dithering phenomenon, be sure to check the exhaust side found jams, electromagnetic valve in the pipeline failure and spring in the actuator is too small rigidity, such as not sure why, contact the manufacturer to solve in time. < br / >
4. To check whether this type of actuator output torque with the current distribution of the body, when the rated output torque required torque is less than the body, also can appear slow or dithering phenomenon, appear such circumstance change the pneumatic valve or replace shape. < br / >
in addition to the above points, if still not solved, it is recommended to use the unit can be directly contact the original manufacturer, can get more reliable treatment method. < br / >
