摘要:
国内中小型天然气液化工厂的LNG装车泵基本上都采用进口的低温卧式离心泵,价格昂贵,并且在实际应用中存在容易泄漏、LNG损失大、安装拆卸过程复杂等问题。本文将潜液泵的概念引入LNG装车泵领域,完成了技术攻关和设备研制,并且依托实际生产项目完成了设备性能测试,实现LNG装车泵设备的国产化和工程化。 

Abstract:
The imported cryogenic horizontal centrifugal pump is widely used for LNG loading pump in domestic small and medium natural gas liquefaction plant. The pumps have some disadvantages, such as expensive price, easy leaking, large LNG loss, and complex installation and removal. The immersed pump was considered to be used for LNG loading pump, and the technical research and equipment development have been completed. Relying on actual LNG plant, the equipment performance testing was also finished to realize the localization and engineering of LNG loading pump.
