2. equipment function: mainly used in the petroleum industry and other research fields, especially the lubricant industry. Through the friction and wear performance test of oil, grease and lubricant, the anti-friction, load-bearing capacity and extreme pressure of the oil are judged, which provides technical support for the final oil performance evaluation.

Technical:

1 drive mode: direct drive, eliminating the influence of the excess drive link on the main speed;
2 loading method: lever-weight, with weight lifting device, convenient and accurate;
3 test load: light load and heavy load, can be selected according to different leverage ratios of 1:10-1:20;
4 loading range [kgf]: maximum 10000, free loading from 5-1000kg;
5 test force relative error: less than ± 1%;
6 Chuck pre-tightening force: custom standard spring collet to meet the standard requirements (light and heavy loads have no effect on them);
7 mechanical properties and accuracy: meet or exceed the requirements of JB/T9395-2004;
8 spindle radial runout [mm]: ≤ 0.01;
9 evaluation indicators: PB, PD, ZMZ. The graph is displayed in real time;
10 spindle operation control mode: manual control, time control, limited friction force, temperature limit, limited friction coefficient;
11 oil cup heating range [°C]: room temperature ~ 250;
