VFBT-4000高真空四球摩擦磨损试验仪

来源:  华汇仪器   作者:  管理员   时间:  2020-03-23 15:13  点击:  

 VFBT-4000高真空四球摩擦磨损试验仪主要模拟航天、航空等特殊环境下的油润滑摩擦磨损状况。用于评价油、脂在真空环境下的摩擦学性能。 

高真空四球摩擦磨损试验仪是先用真空泵将真空环境试验室抽真空,抽去不必要的气体及水分,在真空下通过磁传动技术,实现四球式摩擦实验,通过传感器及计算机数据处理系统得到真空度—摩擦系数的变化关系。

VFBT-4000 High Vacuum Four-ball Friction Wear Tester

          

VFBT-4000 High Vacuum Four-ball Friction Wear Tester is mainly used to simulate the friction and wear of oil lubrication in aerospace, aviation and other special environments. It is used to evaluate the tribological properties of oil and grease in vacuum environment.  


This tester first vacuumizes the vacuum environment laboratory with a vacuum pump to remove unnecessary gases and moisture. Under vacuum, the four ball friction experiment is realized by magnetic transmission technology. The relationship between vacuum degree and friction coefficient is obtained through the sensor and computer data processing system.
