Wear-resistant lining impact and friction and wear performance evaluation testing machine

Abstract

The invention relates to an impact and frictional wear performance evaluation tester for wear-resisting linings. A rotary worktable (4) is mounted on a porous tray (10) of a tester box (3); a sand spraying gun (5) is mounted opposite the rotary worktable (4); a control system (1) is mounted on the upper surface of the top of the tester box (3); a plane laser ranger () is mounted on the lower surface of the top of the tester box (3); a guide tube (9) communicated with the sand spraying gun (5) is communicated with a bottom outlet of a separating sand box (22); a sand guide tube (20) at the upper portion of the separating sand box (22) is communicated with a sand box (6); a dust tube (18) of the separating sand box (22) is communicated with a dust box (19); a duct (7) of an air compressor (8) is communicated with the sand box (6). The impact and frictional wear performance evaluation tester for wear-resisting linings allows the height of multiple wear-resisting linings to be adjusted, can provide multi-angle erosion for the wear-resisting linings, and allows multiple wear-resisting linings to be simulated under the same conditions, so that lining evaluation accuracy and evaluation efficiency are improved.

Description

technical field [0001] The invention relates to a testing machine for evaluating the impact and friction and wear performance of a wear-resistant liner. Background technique [0002] At present, wear-resistant linings are widely used in mines, coal preparation plants, metallurgical industry, thermal power plants and other departments. In order to ensure the smooth progress of material transportation, wear-resistant liners are often installed on the working face of the conveying transfer device to prolong the service life of the material transportation device. At present, the wear-resistant linings used online often use cast high manganese steel linings or surfacing high chromium cast iron linings. When severe wear occurs in some sections of the conveying transfer device, stopping the liner to replace it will affect the normal transportation progress of the material, and the life of the liner has become the focus of relevant enterprises. At present, the evaluation method of...

AI Technical Summary

Problems solved by technology

At present, the evaluation method of the impact wear and friction wear of the liner is through the material friction and wear test machine and the impact wear test machine. Due to the large difference in working conditions, the test results have a large deviation from the field test; Inspection, the disadvantage is that the cycle is long, and it is difficult to measure and collect data
