Electro-hydraulic control system

Electro-hydraulic control system

For the different equipment of construction machinery load-sensitive, negative flow, positive flow hydraulic system developed power system power matching, pumps, valves, motors, cylinders and other hydraulic actuators dedicated control algorithm model, motors, electric cylinders, servo valves and other electric actuators dedicated control algorithm model, equipped with an independent high-performance programmable logic controllers, to achieve flow, pressure, power, torque, speed, displacement, and other physical quantities of the It can realize open-loop and closed-loop control of physical quantities such as flow, pressure, power, torque, speed, displacement, etc., so as to control the responsiveness, smoothness and micro-movement of single action and its combination of composite action such as expansion and contraction, amplitude change, rotation, shoveling and cutting, walking, etc., and to provide an overall solution of electro-hydraulic control for a variety of construction machinery such as lifting machinery, aerial work machinery, agricultural machinery, earth-moving machinery, and mining machinery.

System Advantage:

High control accuracy, error less than 0.5%;

Fast control response, less than 2ms;

Smooth operation without lag; rapid start without impact; sensitive micro-movement fast speed regulation;
