Integral debug method of pneumatic valve electric device

monolithic pneumatic valve electric actuator is pneumatic valve open, closed or adjust the control of drive equipment. Applicable to split ring or closed loop control system in all kinds of butterfly pneumatic valve, pneumatic ball valve to control a device. With complete functions, reliable performance, advanced control system, small volume, light weight, convenient in operation and maintenance, etc. Can implement remote control of pneumatic valve, control, and automatic control. Widely used in electric power, metallurgy, petroleum, chemical industry, paper making, sewage treatment and other industries.
and pneumatic valve electric device control box, the so-called mechanical and electrical integration. With LCD display, can feedback ~ mA standard signal, can determine the pneumatic valve fully open, close, and the uncertainty in the middle of the position, the switch quantity control. Electrical components installed in a reversible plate, so that the torque control mechanism, indicating the stroke control mechanism and the opening mechanism to adjust.
integral whole type pneumatic valve electric actuator module debugging method: manual electric device is placed in the middle position; Turn on the AC power supply, power supply indicator; If power supply phase, the phase indicator; Conventional control when the position feedback signal conditioning. Will play to the electric actuator seated position, adjust the overall module on the 'zero' potentiometer, makes the test point voltage is close to zero, ≤mV) 'MA', and then adjust potentiometer output signal for the mA; Will play to the full open position electric equipment, adjust the potentiometer output signal for mA 'mA'. The above regulation only can be done at a time. Note: 'zero', 'mA', 'mA' potentiometer are clockwise increases output signal, conversely, if discover the potentiometer clockwise, the output signal is reduced, to swap the potentiometer on both sides of the line, please.
controller with internal phase sequence adaptive, open phase protection function module ( XQKM） And running control function board ( DKG - And film panel component and ac contactor, etc, with the scene and the distance control switch control and fault alarm passive contact output, the output and pneumatic valve position signal to mA, and other functions, the scene debugging is extremely convenient, applicable to split ring in the control system of all kinds of pneumatic valve and the switch operation and control.
