The technical research and verification device is composed of a hydraulic oil source system, a force loading system, a friction pair rotating body transmission system and a plunger pump mounting system for simulating the operating environment of a real swash plate type axial plunger pump.According to the technical research and verification device, the operating environment of the real plunger pump is simulated, the whole research and verification device comprises a valve plate, a plunger, a sliding shoe, a chuck, a pressing plate, a swash plate, a rotor, a shaft and other components like the real plunger pump, and even the plunger, the sliding shoe, the chuck, the pressing plate,the swash plate, the rotor, the shaft and the like which are used by the research and verification device are directly from the real plunger pump; and through research on the abrasion mechanism and law of the key friction pair, a new technology and new measures for strengthening and protecting the friction surface and the resultant force stress level can be obtained, and the important significance is achieved for further research on the long-life technology of the plunger pump. The technical research and verification device is scientific in structure and good in manufacturability and has wideapplication and popularization value.

Description

Technical field: [0001] The invention provides a technology research and verification device for a key friction pair of a plunger pump, which belongs to the field of hydraulic transmission. Background technique: [0002] The plunger pump is the "heart" of the hydraulic system, which itself constitutes a small precision mechanical tribological system. The wear life of the plunger pump is much lower than its fatigue life. The reason is that the sharp wear of the key friction pair accelerates the performance decline and restricts the The life of the plunger pump, with the development of the plunger pump to high speed, high pressure, and large flow, the research on the key friction pair technology of the plunger pump has positive significance for improving the life of the plunger pump, and the research on the key friction pair technology of the plunger pump A verification device is essential to conduct research on its technology. At present, there are few studies on this verifi...

Problems solved by technology

At present, there are few studies on this verification device, and the only ones are relatively simple studies that use two friction discs with a simple structure to replace the key friction pair components in the plunger pump, and it is impossible to carry out in-depth research on the friction pair of the plunger pump.
