Fully automatic electro-hydraulic servo deviation-correcting system

Deviation-correcting System Introduction:
The electro-hydraulic servo deviation-correcting system applies the probe-type infrared photoelectric detection technology to closely monitor the production lines of non-transparent metal and non-metal strips, trace the lateral deviation and servo control the deviation. The system outputs standard electrical signal, which is calibrated, amplified and transformed through PID controller and power amplifier and then amplified and transformed to pressure and flow signals through the servo proportional valve to output, so as to control the servo cylinder to transform the electricity to hydraulic energy and output. The system quickly, powerfully, steadily and sequentially drives the uncoiler, coiler or deviation-correcting machine frame to move laterally and precisely control the deviation of strips according to the set pressure and flow values of the hydraulic station, so as to make the strips overcome all external factors during the production process. The system is widely applied to the production lines of rolling, annealing, acid washing, plating, color coating, tension leveling, shearing and re-coiling of metal plates, strips and foils, e.g., plain carbon steel, stainless steel, aluminum, copper plates and strips.
