Abstract: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.
