摘要
简要介绍了成品油铁路接卸主要采用的真空接卸、容积泵辅助离心泵接卸和潜油泵接卸工艺的工作原理及对优缺点进行了比较,分析了在设计选用方面应注意的问题,并针对我国南方地区气温较高,易产生气阻和汽蚀,提出了采用潜油泵接卸工艺及滑片泵底油抽吸工艺进行扫仓的建议。
Three kinds of processes mainly adopted in product oil railway unloading are introduced briefly in this paper,namely vacuum unloading,centrifugal pump unloading assisted by positive displacement pump,and submersible pump unloading.And the working principle and the advantages and disadvantages of three kinds of processes were compared and analyzed.At the same time,the matters needing attention about the design and selection of oil tank wagon unloading processes are pointed out.
