The power loss of power losses in power and efficiency (1) hydraulic pump hydraulic pump have volume loss and mechanical loss of two parts: l) Volume loss volume loss means the loss of the hydraulic pump in the flow of the hydraulic motor, hydraulic pump flow actual output always less than the theoretical flow, mainly due to the leak, the oil inside the compression pump high-pressure chamber and the suction in the suction process due to too much resistance, oil viscosity and pump speed reasons which led to higher oil not all work full seal chamber. Volume loss of the hydraulic pump volumetric efficiency is represented by a hydraulic motor is detected, it is equal to pump flow ratio of actual output to its theoretical flow q qt, namely the actual pump output flow q is 1. Hydraulic motors generally require rotating, so In the internal structure should have symmetry hydraulic motor maintenance, while the pump is generally a single direction of rotation, no such requirement. 2. In order to reduce the suction resistance repair hydraulic motors, reducing the radial force, general pump suction port is larger than the size of the oil port. The low pressure chamber of the hydraulic motor pressure slightly higher than atmospheric pressure, so there is no such requirement. 3. The hydraulic motor requirements can work in a wide speed range, therefore, it should be used hydraulic bearings or hydrostatic bearings. Because when the motor speed is low, the use of hydrodynamic bearings, it is not easy to form a lubricating synovial.
