Flow and displacement of hydraulic pump
Displacement refers to the volume of liquid discharged (or input) obtained by the change of the geometric dimensions of the sealed cavity per revolution of the pump (or motor). The common unit is ml/r (ml/revolution). The displacement can be changed by adjusting to become a variable pump (or variable motor), and the displacement cannot be changed to become a fixed pump (or fixed motor).
The actual flow rate refers to the flow rate 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. Because the motor itself also has internal leakage, to achieve the specified speed, in order to compensate for the leakage, the actual input flow must be greater than the theoretical flow.
Hydraulic pump efficiency
Volumetric efficiency, for hydraulic pumps, refers to the ratio of actual flow to theoretical flow. For hydraulic motors, it refers to the ratio of the theoretical flow to the actual flow.
Mechanical efficiency, for hydraulic pumps, refers to the ratio of its theoretical torque to the actual input torque. The actual output torque of a hydraulic motor is the torque after the theoretical torque overcomes the friction force, so its mechanical efficiency is the ratio of the actual output torque to the theoretical torque.
The total efficiency refers to the ratio of the output power of the pump (or motor) to the input power. The total efficiency is equal to the product of volumetric efficiency and mechanical efficiency.
