Low Pressure Turbine Oil Control System (EH-HLP)
About EH-HLP
The low pressure turbine oil control system retains the power oil source from the original hydraulic control system, which is the main oil pump supply method. The control valve actuatoris converted to an electro-hydraulic servo actuator. The control valve is managed through the original valve mechanism (cam or lift plate). The valve position command signal generated by the DEH system is processed through the servo amplifier board and the electro-hydraulic converter valve, forming the control oil pressure to the throttle valve, thereby actuating the servo motor. The actuator stroke is measured by a displacement sensor and fed back to the input of the servo amplifier board, ensuring it matches the valve position command. This allows the actuator stroke to be fully controlled by the DEH system.
