Abstract

Abstract

In order to design optimally and apply rationally a single pipe ejector, this paper describes the structural and application characteristics of a single pipe ejector system. The basic optimum formulae are created between the parameter relationships of dewatering depth and the size of the ejector, and the performance of the centrifugal pump. It is simple and convenient to select the performance parameters of the centrifugal pump and design a single pipe ejector system according to dewatering depth and yield, and to calculate the yield of the dewatering depth through the ejector and design a deep foundation dewatering system.
