Abstract

The invention relates to the field of impact wear test equipment, and discloses an impact wear test device capable of simulating sand grains and high-temperature complex environments. Through the creation of the present invention, a new type of impact wear test device that can accurately control the impact velocity and can be tested in sand and high temperature environments can be provided. / The method of releasing the punch installation base when the power is turned off realizes the purpose of releasing the punch installation base at the maximum speed to ensure that the impact speed is consistent each time, so that the impact movement can be controlled more accurately. On the other hand, sand feeding mechanism, sand The particle automatic circulation mechanism and the sample heating mechanism realize the research on impact wear in the environment of sand particles and high temperature, and meet the current application requirements.

Description

Technical field [0001] The present invention belongs to the field of impact wear test equipment, and more particularly to an impact wear test device capable of simulating sand and high temperature complex environments. Background technique [0002] Impact wear is surface injury caused by repeatedly dynamic contact between two solid surfaces. In various types of machinery, many components are subject to different degrees of impact wear, and the failure of mechanical components caused by impact micro-monitoring is widely existing in electricity, petrochemical, mine machinery, marine machinery, aerospace and other fields. Brought a large energy waste, greatment of people's property and the national economy brought huge losses. The impact load can cause contact surface damage, which will cause mechanical components to fail. In the type of grinding, impact wear may be the most unfavorable material, understand the least type of wear. To study this wear, so far, many types of testing ma...

AI Technical Summary

Problems solved by technology

[0003] In actual working conditions, the impact wear environment is more complex, such as high temperature, high humidity, dust, mud and rain, which not only affect the impact wear, but also make the impact wear behavior more complicated

Existing impact and wear testing machines are generally only tested at room temperature and air environment, and cannot study the impact and wear behavior in sand and high temperature environments

In addition, the existing impact and wear testing machine does not control the punch speed accurately enough to ensure that each impact speed is consistent, resulting in inaccurate impact and wear testing
