High-back-pressure seawater hydraulic frictional wear test bed

Abstract

The invention discloses a high-back-pressure seawater hydraulic frictional wear test bed. The test bed comprises a support, a high-pressure bin is installed on the support, a pipe joint is arranged on the high-pressure bin, a high-pressure power source injects high-pressure seawater into the high-pressure bin through the pipe joint, an inclined disk assembly and a plunger cylinder block assembly are arranged in the high-pressure bin, one end of the plunger cylinder block assembly is fixedly connected with a valve sleeve through a suction valve, and the other end of the plunger cylinder block assembly makes contact with the inclined disk assembly through a skid shoe. According to the high-back-pressure seawater hydraulic frictional wear test bed, a plunger and cylinder block friction pair, a skid shoe and inclined disk friction pair and a shaft and bearing bush friction pair are arranged in the high-pressure bin in a concentrated mode, and all the friction pairs move at the same time, and thus can be tested at the same time; high-pressure seawater is injected into the high-pressure bin through the pipe joint, a deep sea pressure environment can be simulated, and the conditions of operation of all the friction pairs in the 2000 m deep sea environment can be tested.

Description

technical field [0001] The invention relates to the field of friction and wear experiment equipment, in particular to a high back pressure seawater hydraulic friction and wear test bench in the field. Background technique [0002] Most of the existing friction and wear test benches use one bench to simulate one type of friction pair, and only one pair of friction pairs can be tested at a time. The function is single, and multiple friction pairs need to be tested separately on multiple test benches, resulting in The hydraulic system is complex, occupying a large area, high cost, and cannot simulate the actual working conditions of hydraulic plunger pumps, such as the coupling between friction pairs; most of them use fresh water as the working medium, which cannot simulate the strong corrosion of seawater on materials Function; its ambient pressure is atmospheric pressure, which cannot simulate the operating conditions of friction pairs and sliding bearings in deep-sea high-pr...

[0003] The existing friction and wear test bench adopts a single plunger plate flow distribution scheme, the force of the flow plate is extremely unbalanced, an effective pressure water film cannot be formed, the leakage is large, and the working pressure cannot be established
