摘要
分析了三缸钻井泵泵头焊修工艺目前所存在的问题,介绍了镶套分级修理泵头的修理技术。现场试验及一年来的应用情况表明,采用该项技术修复泵头,可使泵头使用周期比采用原来的焊修工艺提高3倍以上,具有显著的经济效益。
This article presents the shortcomings in the welding-on method now commonly used for repairing the fluid cylinders of triplex drill pumps and introduces a lining method and a step machining method for repairing the fluid cylinders. Field test and yearlong application show that the service life of the fluid cylinders repaired in this way is 4 times longer than those repaired by welding.
