从最近召开的第三次摩擦磨损年会暨学术交流会上获悉,出四川石油管理局和西南石油学院组成的摩擦磨损研究组,经过三年多的努力,已在泥浆泵缸套和活塞的摩擦机理研究方面取得可喜进展。通过单因素试验、摩擦副跟踪测试、活塞接触密封区试验和铁谱分析等,取得了一些新的理性认识,掌握了某些因素的变化关系量值。 Learned from the Third Annual Friction and Wear Conference and Academic Exchange Conference recently that the friction and wear study group consisting of the Sichuan Petroleum Administration and the Southwest Petroleum Institute has worked for more than three years in the mud pump cylinder liner and piston Friction mechanism research made gratifying progress. Through the single factor test, the friction pair tracking test, the piston contact sealing zone test and the iron spectrum analysis, some new rational cognitions have been obtained, and the relationship between some factors has been mastered.
