Improper selection of electric actuator, vibration of control valve, brake failure of electric actuator, hysteresis of output and low sensitivity of servo amplifier will cause low control accuracy of electric actuator. Tianjin tianertong valve small series for you to talk about the above problems, how to do to improve the control accuracy of electric actuator.
Valve electric device is a device which can complete the valve program control, automatic control and remote control. Its movement process can be controlled by the stroke, torque or axial thrust. The operating characteristics and utilization rate of valve electric device depend on the type of valve,
Electric actuator is a kind of control equipment widely used by people nowadays. It has three types: straight stroke, angular stroke and multi rotation. The angle stroke electric actuator takes the motor as the power component, and converts the input DC current signal into the corresponding angular displacement (0-90 degrees). This actuator is suitable for operating rotary control valves such as butterfly valves and baffles. After receiving the input DC current signal, the straight stroke actuator makes the motor rotate, and then decelerates by the reducer and converts it into linear displacement output to operate various control valves such as single seat, double seat, tee and other linear control mechanisms. Multi rotary electric actuator is mainly used to open and close gate valve, stop
How does the electric actuator prevent corrosion? Is it hard to do? Lets have a look (1) Remove the rusted roller, clean the shaft and piston pin, and then apply lubricating grease. If there is no grease filling equipment, the shaft should be added wi
