Specific embodiment
The present invention will be further described with reference to the accompanying drawing:
A kind of anti-suck axial-flow pump, including pump housing pipe 1, Discharging bent-tube 2, pump shaft 3, diffuser 4, impeller 5 and suction hose 6,
For the pump shaft 3 through being arranged inside the pump housing pipe 1, the top of the pump housing pipe 1 is arranged in the Discharging bent-tube 2, described
The lower part of the pump housing pipe 1 is arranged in suction hose 6, and the diffuser 4 and impeller 5 are sequentially fixed at the pump shaft 3 from top to bottom
Lower end, the inside of the Discharging bent-tube 2 is equipped with elastic baffle, and the elastic baffle is by elastic baffle A7 and elastic baffle B8 group
At the upper end of the elastic baffle A7 and the lower end of elastic baffle B8 are hinged with the inner tubal wall of the Discharging bent-tube 2, described
The side of elastic baffle A7 and elastic baffle B8 are connect by compressed spring 10 with the inner tubal wall of the Discharging bent-tube 2, the bullet
Property baffle right side be equipped with spacing collar 9, the spacing collar 9 is fixed on the inside of the Discharging bent-tube 2.
As shown in Figure of description Fig. 1, a kind of anti-suck axial-flow pump, including pump housing pipe 1, Discharging bent-tube 2, pump shaft 3, guide vane
Body 4, impeller 5 and suction hose 6, for pump shaft 3 through being arranged inside pump housing pipe 1, the top of pump housing pipe 1 is arranged in Discharging bent-tube 2, inhales
The lower part of pump housing pipe 1 is arranged in water pipe 6, and diffuser 4 and impeller 5 are sequentially fixed at the lower end of pump shaft 3, Discharging bent-tube from top to bottom
2 inside is equipped with elastic baffle, and elastic baffle is made of elastic baffle A7 and elastic baffle B8, the upper end of elastic baffle A7 and
The lower end of elastic baffle B8 is hinged with the inner tubal wall of Discharging bent-tube 2, and the side of elastic baffle A7 and elastic baffle B8 pass through pressure
Contracting spring 10 is connect with the inner tubal wall of Discharging bent-tube 2, and the right side of elastic baffle is equipped with spacing collar 9, and it is curved that spacing collar 9 is fixed on water outlet
The inside of pipe 2.
The axial-flow pump of the utility model in normal use, water body from Discharging bent-tube 2 be discharged, at this point, elastic baffle A7 and
Elastic baffle B8 stress in opened condition, compressed by compressed spring 10；If axial-flow pump stops working suddenly, elastic baffle A7 and bullet
Property baffle B8 is not by masses hit power, and under the action of compressed spring 10, elastic baffle A7 and elastic baffle B8 restore to closing
State, two block baffles merge into monolith baffle and blind-mate, and spacing collar 9 plays the role of limited support, effectively prevent axis stream
Suck-back phenomenon occurs for pump.
In conclusion the preferred embodiment of only the utility model, is not used to limit the utility model implementation
Range, all equivalent changes according to carried out by shape described in the utility model claims range, construction, feature and spirit with repair
Decorations, should be included in the scope of the claims of the utility model.
