How to prevent pneumatic actuator and positioner connection release?

in the automatic control system, pneumatic actuators in order to achieve the accurate positioning, often put it with the valve positioner. Locator in the controller output signal, will run with the proportional relationship between the output signal to control the pneumatic actuator. In industrial production, the pneumatic actuators may be due to vibration and connection locator release. In order to reduce the load or parking accident, to prevent and check. About the inspection should have specialized departments to formulate standards and rules, transferred specialized staff monthly check regularly according to the provisions of the content of pneumatic actuators connected components. After the check acceptance will result to leadership, and for normal found problems in the process of making overhaul plan. With such activities, pneumatic actuators and electric component connection release problem will be solved.
