AUGER CENTRIFUGAL PUMP WITH MOBILE ELECTRIC DRIVE Russian patent published in 2008 - IPC F04D7/00 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to pumps with removable self-contained drive. Tubular shaft of removable auger is provided with end face splines on one end to connected with mating splines of drive shaft. Shank of drive shaft is detachably connected with adapter whose second end is detachably secured in clamping chuck of screw driver. Housing of screw driver is embraced by tension belt connected with two shackles secured on outer surface of adapter tubular housing. Housing is provided with compensating ring over inner diameter from side of head part of screw driver. Output part of auger housing is dipped into space of centrifugal chamber forming clearance between its end face and plane of disk, and it has conical generatrix of outer surface. Side and end face surfaces of input part of housing for auger are provided with through holes. End face surface has centering hole along axis of housing for end face rod of shaft carrying tubular shaft of removable auger pressed by threaded nut to end face splines of shaft SURFACE. Removal auger, auger housing and cylindrical housing for bearings are made of plastic.

EFFECT: enlarged range of mobile drives for pump, reduced weight of pump, improved mechanical connection of pump and drive and hydraulic parameters.
