The Study of Hydraulic Valve Position Control Based on PLC Controller

Abstract:

With the growing shortage of water today, in order to control the flow of pipe conveyance, it is essential for further study of automatic control valves, especially the automatic control technology of control valve. In this paper, by using programmable control and signal transmission technologies etc. a prototype model of hydraulic valve position control is constructed. Prototype model is designed as the closed-loop of position control system, by using high-precision angular displacement sensor detecting the position of the valve plate, converting the output signal of sensor into an industrial process signal 4-20mA with the low-drift transmitter chip XTR101, and with modular PLC as system control center, using three-phase inverter controlling the steering and speed of motor and cooperating with closed pump control system for hydraulic drive, it achieves the closed-loop control hydraulic valve position. This paper provides some technical support for the better use of water resources.
