Abstract
A submersible pump, and method of making the submersible pump, is disclosed. The pump comprises a housing, a plurality of impeller stages serially disposed in the housing from a bottom impeller stage to a top impeller stage, an impeller stage bypass hole extending through one of the diffusers and a housing bypass hole extending through the housing radially outwardly from one of the impeller stages.
Claims19
A bypass system for a submersible pump, the submersible pump including a housing, a plurality of impeller stages disposed in the housing and aligned in series from a bottom impeller stage to a top impeller stage, each of the impeller stages having a diffuser and an impeller, the system comprising:
- an impeller stage bypass hole extending through a first diffuser of a first impeller stage of said plurality of impeller stages and a housing bypass hole extending through the housing radially outward from a second impeller stage and aligned with said second impeller stage, said impeller stage bypass hole in fluid communication with the housing bypass hole.
A submersible pump comprising:
- a housing;
- a plurality of impeller stages serially disposed in the housing from a bottom impeller stage to a top impeller stage, each of the impeller stages having an impeller in fluid communication with a diffuser to create an impeller stage flow path from the impeller through the diffuser for each of the impeller stages, the diffuser of each impeller stage in fluid communication with an adjacent impeller stage so that the impeller stage flow path of each impeller stage is in fluid communication with the impeller stage flow path of the adjacent impeller stage;
- an impeller stage bypass hole extending through one of the diffusers in fluid communication with the impeller stage flow path of the one of the diffusers, the impeller stage bypass hole defining an entrance aperture and an exit aperture and extending through the diffuser, with the entrance aperture positioned radially outwardly from the impeller, whereby said entrance aperture of said impeller stage bypass hole is in fluid communication with the impeller stage flow path of the one of the diffusers;
- and
- a housing bypass hole extending through the housing radially outwardly from one of the impeller stages, said impeller stage bypass hole in fluid communication with the housing bypass hole.
A method of making a submersible pump, the pump including a housing, a plurality of impeller stages disposed in the housing and aligned in series from a bottom impeller stage to a top impeller stage, each of the impeller stages including a diffuser and an impeller, the method comprising:
- forming an impeller stage bypass hole through a first diffuser of a first impeller stage of the plurality of impeller stages and forming a housing bypass hole extending through the housing radially outward of a second impeller stage and aligned with said second impeller stage, the impeller stage bypass hole in fluid communication with the housing bypass hole.
