Abstract: The device main body structure includes but not limited to high temperature heating control system, rotating ring body, a rotary motor system, block sample conversion system, vacuum system, power control system and support platform. The diameter of the rotating torus is Φ50 mm, the thickness is 2 mm, and the components are bent out of 316L stainless steel. The equipment reserves tungsten ball and sample test mounting interface. The pipe is equipped with a tungsten b-all, and the rotating ring rotates along the axis to simulate the wear of the tungsten ball on the inner wall of the pipe and internal electrical parts at different temperatures and velocities. Circle center pipe diameter is 1000 mm, the limit temperature is 650 ℃ of this equipment, the limiting vacuum is 2 Pa, and the leakage rate of this experimental in each temperature were better than 5×10^-8Pa·m³/s.

Key words: rotation, ultimate temperature, tungsten ball particles
