You’ll understand once you learn to control the oil flow
The electro-hydraulic converter converts electrical signals from the control room into hydraulic pressure signals
The 4-20mA electrical signal is ultimately converted into an opening degree of 0-100% for the speed control valve; this conversion is achieved through an electro-hydraulic converter and a hydraulic actuator. The electrical signal acts on the electro-hydraulic converter, which in turn acts on the hydraulic actuator, and the hydraulic actuator then acts on the speed control valve – it’s a sequential process, a servo relationship
Does the oil in an oil-driven engine use secondary oil pressure or high-pressure oil?
The electrical signal is converted into a pressure oil signal via an electro-hydraulic converter; the amount of intake air is adjusted by controlling the stroke of the hydraulic motor, thereby regulating the load. The oil in the oil-driven engine is pressure oil, which comes from the fuel tank oil pump and the pressure control valve
An electro-hydraulic converter is a device that converts electrical signals into hydraulic signals; the hydraulic actuator is the actuating element
The 4 to 20 mA pad signal is converted by an electro-hydraulic converter into a secondary oil pressure signal of 0.15 to 0.45 MPa, which is used to control the throttle adjustment mechanism. This throttle control mechanism regulates the high-pressure oil flow into the hydraulic actuator, and it is the hydraulic actuator that controls the opening degree of the control valve. Oil-driven motors are powered by control oil.
Where does the secondary oil controlled by the electro-hydraulic converter come from?
The oil for the oil-driven engine is high-pressure oil regulated by a secondary oil regulator
The electro-hydraulic converter is responsible for converting electrical signals into pulse-like changes in oil pressure, which in turn drives the spool of the control valve to move up and down, causing changes in the power oil pressure. This movement then drives the piston of the hydraulic actuator up and down, thereby achieving the purpose of regulation
