The large-scale bulb tubular pump is good in hydraulic performance but with complex structures. According to the characteristics of Linjiaba pumping station of the east route project of South-to-North Water Diversion, the general arrangements and supporting structures of largescale gear-driven bulb tubular pump had been designed and investigated, in order to ensure that it could run safely, stably and efficiently. The structures of vane angle adjustment, the seals of vanes, main shaft seal apparatus and bearing supports were discussed and this research provided reference for design and manufacture of other similar bulb tubular pump sets.
