通过用铁谱技术对钻井泵缸套活塞材料磨损试验及台架试验的监控,同时对在现场所取的工作泥浆中的磨屑进行对照分析研究,发现在钻井泵缸套活塞的磨损过程中所产生的磨屑主要是正常摩擦磨损磨屑、具有疲劳及粘着特征的磨屑以及少量的切削磨损磨屑。这三种磨屑的存在表明这对摩擦副间的磨损是疲劳磨损、粘着磨损及磨粒磨损等所形成的综合磨损。 By using ferrography to monitor the piston material wear of drilling pump liner and the test of bench test, at the same time, comparing and analyzing the wear debris in the working slurry taken at the site, it was found that during the wear process of piston of drilling pump liner, The resulting debris is mainly normal wear friction wear debris, wear and adhesion characteristics with wear debris and a small amount of wear debris cutting. The existence of these three types of wear debris shows that the pair of friction wear is fatigue wear, adhesion wear and abrasive wear, etc. formed by the composite wear and tear.
