屏蔽泵石墨轴承材料的强度和耐磨性研究

对屏蔽泵的石墨轴承材料的强度、磨损性和摩擦系数进行了实验研究。在DWD-3020电子万能试验机上对普通石墨和浸润树脂石墨材料的弹性模量进行了测定，同时确定了材料的拉伸和压缩强度极限。在Falex摩擦磨损机上对材料进行了磨损试验，得到了转速和载荷对这两种材料磨损的影响，并利用CSM950扫描电子显微镜对其摩擦表面作了形貌分析。

Experimental Research on the Wearability of Graphite Bearing of Canned Motor Pump

This experimental research is on the intensity,wearability and friction coefficient of graphite bearing of a canned motor pump.The elastic modulo of common graphite and infiltration epoxide resin graphite,and the limits of graphite's strech and compression were measured on DWD-3020,which is an electron measure apparatus. Then a series of abrasive experiments on the material were carried out on Falex tribology test equipment, by which the influences of speed and load on the grinding material were got. And CSM950,a scanning electron microscope(SEM) equipment, was used to analysis the fracture morphology on the wear surface.
