Abrasion experiment equipment

Abstract

The invention relates to the technical field of ultra-high molecular weight polyethylene ultrafine material experimental equipment, in particular to abrasion experimental equipment. The abrasion experimental equipment comprises a sample barrel, a push-pull cylinder is arranged at the bottom of the sample barrel and mounted on a bottom plate, a cover plate is arranged above the sample barrel, a stirring shaft penetrates through the middle of the cover plate, the upper end of the stirring shaft is connected with a motor, and the motor and the cover plate are mounted on a top plate; two sides of the sample cylinder are respectively communicated with a feeding pipe and a discharging pipe, one end of the feeding pipe and one end of the discharging pipe are respectively provided with a piston cylinder body and an elastic fluctuation pipe, and the ends, close to the piston cylinder body and the elastic fluctuation pipe, of the feeding pipe and the discharging pipe are communicated with a light and heavy material separator through a material returning communicating pipe and a discharging communicating pipe; according to the invention, the abrasion material is not only subjected to one-way rotation abrasion, but also subjected to friction of transverse reciprocating motion of the wear medium in the sample cylinder, so that the abrasion material simulates to bear more disordered friction and is closer to the actual condition, and the test accuracy can be improved.

Description

technical field [0001] The invention relates to the technical field of ultra-high molecular weight polyethylene ultrafine material experimental equipment, in particular to an abrasion experimental equipment. Background technique [0002] The purpose of the abrasion test is to determine the abrasion resistance of the material. Abrasion is a phenomenon in which two solid surfaces are in contact with each other, and the surface material falls off after friction. Abrasion can be classified into four mechanisms according to its causes. 1. Adhesive wear: When solid surfaces are in contact, the high and low peaks will hinder the 100% contact between the two solid surfaces. The protruding parts are in contact with each other, and are plastically deformed due to the large pressure, which acts as a cold weld, such as figure 1 Adhesion phenomenon shown. The adhesive part shears one side of the weaker material due to friction and sliding, causing the material to be adhered from the w...

AI Technical Summary

Problems solved by technology

[0004] (1) The traditional wear test is to use the stirring shaft to drive the wear material to rotate continuously in the wear medium, so as to measure the wear resistance of the material. Friction is disordered, multi-directional, single-directional test, the effect is weak, and the accuracy of the test results is not enough

[0005] (2) During the abrasion test, due to the continuous friction of the abrasive material in the abrasive medium, the temperature in the sample cylinder will continue to rise. Excessively high temperature will affect the accuracy of the test results, and the cooling effect of the existing device is poor.
