Hydraulic pump flow distribution pair lubrication characteristic on-line testing device

The invention provides a hydraulic pump flow distribution pair lubrication characteristic on-line testing device, and relates to the technical field of hydraulic element testing, the hydraulic pump flow distribution pair lubrication characteristic on-line testing device comprises a simulation part, a rotation part, a pushing part and a detection part, and is designed based on the thought of stripping a flow distribution pair, so that no redundant structure interferes with the detection process in the detection process, and the detection efficiency is improved. The whole device is compact in structure, complete in function and convenient to disassemble and assemble. The detection part is installed on the valve plate, online testing of oil film characteristics, a pressure field and a temperature field can be carried out at the same time, data can be collected, summarized and processed in real time in combination with the industrial personal computer, and the testing result is clear. And the detection part is mo
