Impact wear testing device capable of simulating sand and high-temperature complex environments

Abstract

The invention relates to the field of impact wear testing devices, and discloses an impact wear testing device capable of simulating sand and high-temperature complex environments. According to the impact wear testing device capable of simulating the sand and high-temperature complex environments in the invention, a novel impact wear testing device capable of precisely controlling the impact speedand realizing a test in sand and high-temperature environments can be provided; on one hand, a punch installation base is released at the maximum speed in a manner that an impact electric chuck is electrified to adsorb/de-electrified to release the punch installation base according to a certain rule, so that the purpose that the impact speed is consistent every time can be ensured; therefore, theimpact motion can be controlled more precisely; on the other hand, research on the impact wear in the sand and high-temperature environments can be realized by adoption of a sand feeding mechanism, an automatic sand circulating mechanism and a sample heating mechanism; and current application requirements are satisfied.

Description

technical field [0001] The invention belongs to the field of impact wear test equipment, in particular to an impact wear test device capable of simulating sand grains and high-temperature complex environments. Background technique [0002] Impact wear is the surface damage caused by repeated dynamic contact and impact between two solid surfaces. In all kinds of machinery, many parts are subjected to different degrees of impact wear, and the failure of mechanical parts caused by impact fretting wear widely exists in the fields of electric power, petrochemical, mining machinery, marine machinery, aerospace and other fields. Bring bigger energy waste, brought huge loss to people's property security and national economy. Shock loads can cause damage to contact surfaces and, in severe cases, lead to failure of mechanical components. Of the types of wear failure, impact wear is probably the most materially detrimental and least understood type of wear. In order to study this ki...

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
