大型悬吊井筒抽芯式泵机组安装质量控制

由于悬吊井筒抽芯式泵机组结构不同于传统的苏式泵，按原有的规范和要求不能保证该型机组安装检修质量．仅以厂家提供的说明书要求进行安装，因制造工艺、精度等原因，运行过程中，机组稳定性差，故障率高等一直困扰着使用单位．为保证机组安装质量，消除机组运行中常见的不正常现象和故障，以64LKXA-24．5型立式泵机组为例，针对该型机组结构形式的特殊性，根据规范的安装要求，结合安装检修过程中存在的问题，介绍了该形式泵机组的主要安装方法，提出了相应的注意事项．

Controlling the installing quality of overhang-well-vertical-draw out core pumping set

Because the structure of the overhang-well-vertical pumping set is different from the traditional pumping set, it is not able to assure the quality of installing and repairing according to the standard demand. In order to assure the quality of the installing of the set and to avoid the trouble and deviant phenomena at work, taking the type of 64LKXA - 24.5 standing pumping set as example, in allusion to the particularity of the structure of the overhang-well vertical draw out core pumping set, combining with the existent question and peculiarity in the course of installing, the main installing method of the pumps was intruduced, and the corresponding notice was given.
