Second end opening of cylindrical tube, annular flow passage is detachably secured to cylindrical tube intracoelomic cavity, annular flow passage
Collect water that impeller throws away and lead to delivery port, gland and annular flow passage center offer through hole power supply machine output shaft and worn
Cross.
Annular flow passage is coupled to cylindrical tube inwall by way of neck.
Annular flow passage is fixed on cylindrical tube by way of screwing or welding.
The one side of end cap dorsad impeller is provided with annular groove, is provided with annular-heating part in groove.
End cap center offers water inlet, and water inlet pipe is fixed by socket in water inlet with bushing.
The utility model splits out flow channel from pump case, is used as single element.Flowing on centrifugal water pump
The structure and shape of passage can just be needed according to the actual use of centrifugal pump and working condition is manufactured into different specifications and models,
Assembled with the pump case cylinder of identical appearance size, so that so that the hydraulic efficiency and noise level of pump reach optimal effect
Really.

Embodiment
As Fig. 4~8 show the utility model carry independent flow channels structure centrifugal pump, it include pump case, one
Impeller 7, the motor 9 comprising stator core and rotor magnetic core rotated in pump case intracavitary.Pump case is containing and conveying liquid
Volute housing, it is by the cylindrical tube 20 of a both ends open, an end cap 2, a gland 8 and one independently of cylinder
The annular flow passage 30 of cylinder is constituted, and the side wall of cylindrical tube 20 offers delivery port；The of the closing cylindrical tube of end cap 2
One end open, its center offers water inlet；Gland 8 closes the second end opening of cylindrical tube, end cap 2, cylindrical tube
20th, gland 8 encloses pump chamber jointly.Annular flow passage 30 is detachably secured to cylindrical tube intracoelomic cavity, and its effect is
Collect water that impeller throws away and lead to delivery port, by the continuous increase of its cross-section of river to reduce the loss of flood peak.Gland 8 and ring
The center of shape flow channel 30 offers through hole power supply machine output shaft and passed through.
Annular flow passage is coupled to cylindrical tube inwall by way of neck.Specific way can be, in stream
