山西11选5开奖结果查询结果 www.gdvwc.com Application and charateristics:
The machine can change temperature, load, speed, friction materials, friction surface roughness, hardness and other parameters and change the lubricant state (no oil lubricant, lubricant or oil immersed lubrication) in various cases, friction between the friction pair to achieve different simulation test.
This machine can simulate rolling, sliding and rolling sliding friction composite movement form, with a variety of friction pair, such as pin on disk (with big disk and the small, single needle and three needle) firction pair, four ball friction pair, the thrust ring, ball on disc, etc. Can complete a variety of point, line, surface friction simulation experiment. Can be used to assess lubricant, metal, paint, coating, rubber, ceramics and so on friction and wear properties of metarials.
The machine is suitable for various professional field of tribology, can satisfy the tribological study of petroleum chemical industry, machinery, energy, metallurgy, aerospace and the development of the indusry users, the detection of various high-end series of oil, oil products and new materials development, research on the new technology of friction and wear test requirements.
