Description
Technical field
The present invention relates to hydraulic efficiency system technical field, particularly, relate to complex liquid force feed and its production and use.
Background technology
Friction pair is key component in the industrial instrumentation equipment such as hydro-pump, and current hydro-pump is just towards high speed, high-pressure trend and long lifetime future development.But high-voltage high-speedization certainly will bring repeated load, the aggravation of the problems such as high-frequency percussion and system temperature rise makes friction pair boundary lubrication friction behavior more complicated, causes hydro-pump that premature abrasion in use often occurs and destroys.So the premature abrasion problem of friction pair is the problem that the industrial instrumentation device fabrication industries such as hydro-pump briefly solve for a long time always.
At present, hydro-pump friction pair coordinates with face, copper alloy face primarily of bearing steel, because easily there is rupture of oil film under high-voltage high-speed operating mode, metal directly being contacted and produces a large amount of heat, and then produces metal occlusion formation adhesive wear.Up to the present, scientific and technical personnel mainly reduce wearing and tearing around the process for treating surface of friction pair, particularly electroplate and Nitrizing Treatment.Although coating self-lubricating silverskin can promote that lubrication reduces adhesive wear, the limited repair rate of its service life is high.Meanwhile, hard swarf particles one side deterioration surface of friction pair drastically influence hydraulic oil pipeline circulation and tightness system on the other hand.
Therefore, a kind ofly friction pair can be made to reduce wear under high-voltage high-speed and high temperature complex working condition improve the product in life-span and method in the urgent need to proposing
Summary of the invention
The present invention is intended at least to solve one of technical problem existed in prior art.For this reason, one object of the present invention is that proposing one can reduce friction pair wearing and tearing effectively, especially can keep the complex liquid force feed of excellent antifriction effect and wear-resisting stability under high temperature and different loads operating mode.
