Design and Matching Calculation of Hydraulic Helical Axial Multiphase Pump
Helical axial multiphase pump is a new kind of pump which can pump and transport a mixture of oil, water and gas. The greatest advantage of the pump is that it can pump and transport gas and fluid at the same time, can adapt air plug and liquid slug and is insensitive to solid particle. The pump is currently drived by submersible motor. However, hydraulic drive, a new kind of drive type, is firstly put forward in this paper. This paper introduces the structure of the hydraulic helical axial multiphase pump, offers an evidence for the research development and production of the pump, deduces the calculating method of power matching of the pump and provides theory basis for the application of the new-type pump in oil exploitation in the future.
