The Design and Research on Devices Selection for Bifurcate Silo Tubular Pumping Station

This paper introduces the structural characteristics, technical parameters and the type-selection of the devices for bifurcate silo tubular pump sets, such as the hydraulic models, gear cases, bearings and sealing, and motors, on the basis of type selection and study of bifurcate silo tubular pump sets in Huangmayong Pumping Station. It is expatiated that the bifurcate silo tubular pump set has the merits of simple structure, easy installation and maintenance, and high operation efficiency in actual use. The passage structure mode on two sides of the silo is analyzed, and the structure and installation of the equipments inside the silo are also studied. Suggestions on improvement of the pump set are also proposed so that it can be widely used in the projects of irrigation, waterlogging and flood control in the areas with river networks.
