摘　　要：介绍了新研制潜液泵的结构组成和工作原理,论述了研制中对关键技术问题的分析和解决。经试验和初步使用证明满足使用要求,与普通的低温离心泵相比,具有零泄漏、绝热和防爆可靠等优点。The composition and working principle of newly developed submerged pump was introduced, the resolution of key issues in development of submerged pump was analyzed and discussed. After test and initial use of evidence, the submerged pump met the requirement and had advantages of zero leakage, insu- lation, reliable explosion-proof performance comparing with ordinary cryogenic centrifugal pump.
