简要介绍了立式低温离心泵和金属膜片联轴器的结构和工作原理,以及立式低温离心泵常见故障和原因分析,得出了立式低温泵常见故障与联轴器的安装好坏有直接或者间接的关系,在吐哈油田销售事业部轻烃储运工区随着装车量的加大和储罐压力的提高,将传统使用的固定式凸缘联轴器更换为金属膜片联轴器,分析了改造后的使用情况和经济优势,不但节约维修时间,维修费用明显降低,而且提高了机泵的运行效率,更换后效果显著。
Briefly introduced the vertical low temperature centrifugal pump and the metal diaphragm coupling structure and working principle, as well as the vertical low temperature centrifugal pump common fault and the reason analysis, obtained the vertical cryogenic pump common fault and the coupling installment good or bad There is a direct or indirect relationship in the light hydrocarbon storage and transportation area of Tuha Oilfield Sales Division with the increase of loading volume and pressure of storage tank, the traditional fixed flange coupling is replaced with metal diaphragm coupling The analysis of the use of the transformation and economic advantages, not only save maintenance time, significantly reduce maintenance costs, but also improve the efficiency of the pump, the replacement effect is significant.
