机泵是炼油厂工艺流程的心脏。据统计,离心泵约占炼油厂全部回转机械的85%。从多年的生产实践中,发现我国设计制造的离心油泵存在一些极待改进的结构设计问题。在此笔者提出几点建议:
Pump is the heart of the refinery process. According to statistics, centrifugal pumps account for about 85% of all rotary machinery in the refinery. From many years of production practice, we find that there are some problems to be solved in the structural design of centrifugal oil pumps designed and manufactured in our country. In this author made a few suggestions:
