Embodiment
Below in conjunction with accompanying drawing enforcement of the present utility model is further elaborated.
As shown in the figure, this novel water pump comprises rotor and stator two-part, and described rotor portion is made up of rotating shaft (1), mechanical sealing linkage ring, impeller (some), spacer sleeve (some), bearing moving-coil and axle cap.Described stationary part is by lining dish (6), mechanical sealing static ring, and final stage diversion disk, diversion disk (some), bearing Jing Quan and the pump housing are formed.The stator (7) of blade body of described impeller (4) and diversion disk all adopts the press tool global formation.
Above-mentioned impeller is by blade body (4) and be located at front shroud (3) and base plate (5) formation of impeller blade axon to two side ends respectively, described impeller blade body is provided with a plurality of radially vortex-like outward extending blades (15), two adjacent blades are linked into one by the vertical bending part (14) of its side, form a plurality of open type runners, wherein the open type runner of half is towards the front shroud side, and second half open type runner is towards the base plate side.Blade and front shroud and base plate assembling back form the runner of a plurality of closures.Described blade is made of single stamping part.
Guide plate, the disc shaft stator (7) and the cover plate (8) outside the stator laterally of edge part constitute above-mentioned diversion disk to the inside by the black box in the middle part of disk (10), the inside side of disc shaft, disc shaft, the stator of described diversion disk is provided with a plurality of radially vortex-like outward extending blades (18), two adjacent blades are linked into one by the vertical bending part (17) of its side, form a plurality of open type runners, wherein the open type runner of half is towards disk side, and second half open type runner is towards the cover plate side.Described stator and disk and cover plate assembling back form the runner of a plurality of closures.Described stator is made of single stamping part.
The disk periphery wall of above-mentioned final stage diversion disk (20) is provided with radially weep hole (2).
The black box of above-mentioned diversion disk by the sealed support (13) that is connected to the inside with disc shaft, be located at the seal ring (12) in the sealed support outside and cover seal ring lid (11) formation that is interlocked with sealed support on seal ring.
The disc shaft of above-mentioned diversion disk is provided with to the inside and is used to change flow direction, makes the guide plate (9) that enters the next stage diversion disk from the fluid of impeller discharge more swimmingly.
The blade body of above-mentioned impeller is provided with several openings (16) that make things convenient for fluid to pass through that are circumference uniform distribution in the side that links near axle center and front shroud.
The side end face that the stator of above-mentioned diversion disk is connected with disk is provided with several openings (19) that make things convenient for current to pass through that are circumference uniform distribution near the place in axle center.
The working principle of the utility model water pump is achieved in that driven by motor rotating shaft rotation, be fixed on impeller in the rotating shaft with the rotating shaft high speed rotating, fluid is from the water intake intake impeller of the pump housing, centrifugal motion is done in rotation with impeller, the fluid of discharging from the runner outer rim of impeller is after the effect of guide plate, change the flow direction, the stator of process next stage diversion disk enters the next stage impeller.So continuous circulation.Radially weep hole from the periphery wall of final stage diversion disk disk enters the pump housing then, discharges through pump housing water outlet.Because a plurality of impeller serials use, this novel water pump has very high lift.
The utility model is reasonable in design, and structure is unique, not only is convenient to assembling and processing, enhance productivity greatly and accuracy of manufacturing, and also the overall efficiency height, help cutting down the consumption of energy, have bigger promotional value, its market prospects are considerable.
Though the utility model discloses as above with preferred embodiment; so it is not of the present utility model in order to limit; have in the technical field under any and know the knowledgeable usually; in not breaking away from spirit and scope of the present utility model; when can doing a little change and retouching, therefore protection domain of the present utility model is as the criterion as the claim person of defining that look claims.
