AI Technical Summary

Problems solved by technology

[0003] One is that the structure of a high-temperature vacuum friction and wear testing machine has changed greatly from the existing friction and wear testing machine and high-temperature friction and wear testing machine, which is not conducive to the integrated use of equipment. Multiple equipment is required to perform different tests, and the actual operation is extremely inconvenient , resulting in a serious waste of resources;

[0004] The second is that a high-temperature vacuum friction and wear testing machine does not have a good heat dissipation function, which may easily cause excessive heating and excessive residual temperature transmission, resulting in the overall high temperature of the equipment, causing the equipment to not work normally and the experimental data to be inaccurate;

[0005] The third is to add a vacuum system to the high-temperature friction and wear testing machine to realize the function of vacuum high-temperature friction and wear testing. , when the force measurement results are inaccurate
