The pressure of positive displacement hydraulic pump and hydraulic motor (1) Rated pressure pn The rated pressure of hydraulic pump refers to the maximum pressure that can be continuously operated according to the test standard under normal working conditions. Hydraulic motor rated pressure refers to the continuous operation within the specified speed range, and to ensure the design of the life of the maximum input pressure. Its value by the hydraulic pump and hydraulic motor structure, strength, volumetric efficiency, service life and other restrictions. (2) working pressure p in the actual work, the hydraulic pump outlet pressure or hydraulic motor inlet pressure is called the working pressure. The working pressure of the hydraulic pump and the hydraulic motor depends on the load it is trying to push, its value should not be higher than its rated pressure, otherwise overload. Overload is detrimental to the life and safety of hydraulic pumps and hydraulic motors. Hydraulic motor work, the outlet pressure p0 is not always zero. Hydraulic motor outlet pressure is called back pressure. Although the back pressure of the hydraulic motor consumes a part of energy, it can make the operation more stable. (3) The maximum pressure according to test standards, allowing a short period of time to overload the operation of the ultimate pressure.
