摘要
简要回顾了深井泵的发展历史.针对深井泵的研究情况,分别从其结构演变、水力设计方法、轴向力平衡方法等方面进行了较为详细的介绍.通过分析国内外深井泵的研究现状,指出了格兰富公司生产的冲压不锈钢井泵是具有广阔发展前途的产品,而采用专利技术"一种叶轮自身平衡轴向力的多级离心泵"生产的新型井泵代表了深井泵一个更新换代的优秀品种.同时指出利用数值模拟来进行平衡轴向力研究是一种有效的方法.
A brief history of development of deep well pump was reviewed. The structure, the hydraulic design, and the axial thrust were discussed in details. The viewpoint is presented that the stamping and welding well pump made by Grundfos Co. is a product with wide prospect according to the surveys on the present domestic and abroad technologies. It is also pionted out that deep well pump using the patent of ＂a kind of axial thrust self-balance for the multi-stage centrifugal pump＂ represents an excellent replacing product in the future. Numerical simulation in the balance of axial thrust is an effective method.
