Abstract
The utility model provides a self priming pump which consists of a work impeller, a scroll casing and a sealing impeller. A pump case suction flange is connected with the undersurface of the center of a pump case connecting plate. A pump case inlet flange is arranged at the other end. An electric air valve is arranged above the pipeline of the pump case inlet flange. The upper end of the pump case connecting plate is connected with a pump body. A pump case outlet flange is arranged on the left side of a pump body shell. A cone is arranged above the center of the pump case connecting plate and communicated with the pump case suction flange. An inner chamber is formed by connecting the cone with the scroll casing and the work impeller is arranged in the inner chamber. The scroll casing is communicated with the pump case outlet flange. The work impeller is sleeved on the lower end of the pump shaft. A coupling is arranged at the upper end of the pump shaft. A sealing base is arranged at the lower part of the coupling. The sealing impeller is arranged in the inner chamber of the sealing base. A sealing impeller cover is arranged under the sealing impeller and locked by a locking cap. As a result, the sealing effect is good, the suction capacity is strong and the aim of 'once water-spreading, suction forever' is achieved.
Description
Technical field: the utility model relates to pump, particularly relates to a kind of self-priming pump.
Background technique: present pump can not self-priming, and pump is shut down the back medium all can flow to the inlet opening.Here it is described siphonage when using pump, all must at first carry out drainage at every turn, and the ducted air of pump is discharged.Each drainage all consumes human and material resources, the energy, causes very big economic loss.
Summary of the invention: the purpose of this utility model will provide a kind of self-priming pump exactly, and it can overcome the existing problem of above product well.The purpose of this utility model is to realize like this, a kind of self-priming pump, formed by column, running wheel, spiral case, sealing impeller, it is characterized in that: base plate is provided with column, column is provided with the pump case connecting base, and the pump case connecting base is provided with the pump case connecting plate, the following pump case suction inlet flange that connecting of pump case connecting plate central authorities, the other end of pump case suction inlet flanged pipe is provided with the pump case suction flange, is provided with the electric air valve above pump case suction flange pipeline; The upper end of pump case connecting plate connects with the pump housing, and the left side of pump housing shell is provided with the pump case outlet(discharge) flange; Be provided with cone above the pump case connecting plate central authorities, and communicate in pump case suction inlet flange, cone connects the formation inner chamber with spiral case, running wheel is arranged on wherein, and spiral case communicates with the pump case outlet(discharge) flange; Running wheel is enclosed within the following top of pump shaft and is locked by locking and cap, the upper end of pump shaft is provided with coupling, the below of coupling is provided with sealing seat, the upper end of sealing seat connects with support, be provided with the sealing impeller in the inner chamber of sealing seat, be provided with sealing wheel cover plate below the sealing impeller, and by locking and cap locking; The other end of described coupling connects with motor shaft, and motor is arranged on the support, and support connects with the upper end of the pump housing.The utility model is simple in structure, good sealing effect, and suction capacity is strong, can reach " drainage, lifelong self-priming ", reduces cost, and increases economic efficiency, and improves the purpose in the working life of pump.
Description of drawings:
Fig. 1 is the utility model structural representation;
1. column is 2. locked and cap, 3. running wheel, 4. pump case connecting base, 5. spiral case, 6. pump shaft, 7. locking and cap 8. seal wheel cover plate, 9. sealing seat, 10. sealing impeller, 11. pump case outlet(discharge) flanges, 12. supports, 13. motor, 14. coupling, 15. pad A, 16. pad B, 17. electric air valve, 18. wear ring, 19. pump case suction flanges, 20. pump housings, 21. cone, 22. pump case suction inlet flange, 23. pump case connecting plates, 24. base plates.
Embodiment: the utility model is described in further detail below in conjunction with accompanying drawing;
In the drawings, a kind of self-priming pump, formed by column, running wheel, spiral case, sealing impeller, it is characterized in that: base plate 24 is provided with column 1, column 1 is provided with pump case connecting base 4, and pump case connecting base 4 is provided with pump case connecting plate 23, the following pump case suction inlet flange 22 that connecting of pump case connecting plate 23 central authorities, the other end of pump case suction inlet flange 22 pipelines is provided with pump case suction flange 19, is provided with electric air valve 17 above pump case suction flange 19 pipelines; The upper end of pump case connecting plate 23 connects with the pump housing 20, and the left side of the pump housing 20 shells is provided with pump case outlet(discharge) flange 11; Be provided with cone 21 above pump case connecting plate 23 central authorities, and communicate in pump case suction inlet flange 22, cone 21 connects the formation inner chamber with spiral case 5, running wheel 3 is arranged on wherein, and spiral case 5 communicates with pump case outlet(discharge) flange 11; Running wheel 3 is enclosed within the following top of pump shaft 6 and is locked by locking and cap 2, the upper end of pump shaft 6 is provided with coupling 14, the below of coupling 14 is provided with sealing seat 9, the upper end of sealing seat 9 connects with support 12, be provided with sealing impeller 10 in the inner chamber of sealing seat 9, be provided with sealing wheel cover plate 8 below the sealing impeller 10, and by locking and cap 7 lockings; The other end of described coupling 14 connects with 13 in motor, and motor 13 is arranged on the support 12, and support 12 connects with the upper end of the pump housing 20.During concrete enforcement, after self-priming pump is connected power supply, the driven by motor coupling, coupling drives pump shaft, pump shaft drives running wheel work, medium is sucked the running wheel inner chamber through pump case suction flange to pipeline through pump case suction inlet flange to cone, running wheel is sent most medium to spiral case into the pump case outlet(discharge) flange, sub-fraction will upwards be scurried through axial play, owing to be provided with sealing impeller and sealing wheel cover plate in the sealing seat inner chamber, and after the pump starting, the sealing impeller is also along with rotation, the medium of upwards scurrying is screwed off, finally flow into pump case outlet(discharge) flange place, so sealing effect has obtained the assurance of essence.In addition, be provided with the electric air valve above pump case suction flange pipeline, after pump quits work, it will make pump line road inner chamber communicate with barometric pressure, thereby thoroughly overcome the inevitable siphonage that produces of self-priming pump, reached the purpose of " drainage, lifelong self-priming ".
