3. Displacement and flow
The displacement refers to the volume of discharged (or input) liquid obtained from the change of the geometric dimension of the sealing chamber every revolution of the pump (or motor), and the common unit is ml/r (ml/revolution). The variable displacement pump (or variable displacement motor) can be changed by adjustment, and the constant displacement pump (or constant displacement motor) can not be changed.
The actual flow refers to the flow at the outlet (or inlet) when the pump (or motor) is working. Due to the internal leakage of the pump itself, its actual flow is less than the theoretical flow. Since the motor itself also has internal leakage, to achieve * * * speed, in order to compensate for leakage, its input actual flow must be greater than the theoretical flow.
4. Efficiency
Volumetric efficiency, for a hydraulic pump, refers to the ratio of its actual flow to its theoretical flow. For hydraulic motor, it refers to the ratio of its theoretical flow and actual flow.
Mechanical efficiency refers to the ratio of theoretical torque to actual input torque for hydraulic pump. For the hydraulic motor, the actual output torque is the torque after the theoretical torque overcomes the friction, so the mechanical efficiency is the ratio of the actual output torque and the theoretical torque.
The total efficiency refers to the ratio of output power and input power of the pump (or motor). The total efficiency is equal to the product of volumetric efficiency and mechanical efficiency.
