According to the combination of hydraulic pump and hydraulic motor, which forms of the volumetric regulation circuit?
There are three main types of governing circuit Throttle control circuit; The speed adjustment is achieved by using the flow valve to adjust the flow of the actuator into or out of the actuator The volumetric speed regulating circuit is used to adjust the displacement of the variable pump or variable motor.
Volumetric throttle control circuit The flow valve is adjusted by the flow valve to the flow of the actuator, and the flow of the variable pump is applicable to the regulating flow of the regulator In addition, it is possible to use several quantitative pumps in parallel, at different speeds, to start a pump or multiple pumps to realize the speed adjustment. If the prime mover for the internal combustion engine driven hydraulic pump, also can be changed by adjusting the engine speed quantitative pump rotation speed, the flow of hydraulic actuators to change the input speed.
According to the different methods of hydraulic pump and hydraulic motor, volumetric speed control loop with quantitative pump variable motor, variable pump motor (or hydraulic cylinder), the variable pump - variable motor circuit. If the oil circuit can be divided into open speed regulating circuit and closed speed regulating circuit.
