隔膜泵泄压流程改造探讨

The discussion on the pressure relief process transformation of diaphragm pump

近年来,靖边气田各采气作业区陆续对集气站上所有的注醇泵泵头进行了改造,将原来柱塞式注醇泵改为隔膜式注醇泵,现场使用效果良好。隔膜泵泵头自带泄压阀,其结构与弹簧式安全阀相似,结构简单,在性能上可以代替安全阀,起到防止注醇泵超压,保护泵头的作用。为了优化隔膜式注醇泵泄压保护功能,作出了对泄压流程进行改造的工艺设想,并进行可行性分析、现场试验及安全经济评价,同时提出了改造后的维护与管理建议。

In recent years,the work area in Jingbian gas field has consecutively transformed heads of all alcohol injection pumps in gas gathering station,i.e.change the original plunger type alcohol injection pumps into diaphragm type alcohol injection pumps,the onsite using effect was very good.The head of diaphragm pump is equipped with pressure release valve,its structure is similar to spring type relief valve,and its structure is simple.It can be used to replace relief valve,in order to prevent overpressure on alcohol injection pump and protect pump head.In order to optimize the function of protection of the diaphragm pump pressure release valve,it proposes the idea of carrying out transformation on pressure relief process, as well as carry out feasibility analysis,on-site test,safeeconomic evaluation,meanwhile it also provides out maintenance and management suggestion after transformation.
