Abstract

The utility model relates to a coaxial water suction pump, which relates to the field of a pump, in particular to a coaxial water suction pump. The coaxial water suction pump comprises a pump body, a motor, a water vane, a rotary shaft, a spiral housing, a water inlet and a water outlet. The motor is directly connected with one end of the rotary shaft and arranged with the rotary shaft horizontally. The other end of the rotary shaft is provided with the water vane. The position of the water vane is fixed by a water vane screw. The water vane is located in the spiral housing and arranged vertically. The central axis of the water inlet is superposed with the central axis of the rotary shaft. The central axis of the water outlet is vertical to the horizontal line, and superposed with the vertical axis where the water vane is. The coaxial water suction pump provided by the utility model is simple to install, stable to operate, and strong in working performance.

Description

Coaxial suction pump
Technical field
The utility model relates to the pump field, particularly a kind of suction pump of coaxial-type.
Background technique
Existing coaxial suction pump satisfies general industrial requirement, pumps agricultural water, industrial water supply, the building feedwater is often in the design of these pumps, owing to will consider the operating conditions of suction pump, must add check valve, owing in the general water, have unavoidably impurity, adding cotton yarn at check valve also is very important, these mechanisms that newly add can solve some technical problems, but also can increase cost, cause difficulty for the maintenance of pump structure.In the prior art, during pump housing work, the waterleaf rotational noise is large, and the pump housing is not steady, also will build in addition the chamber of drawing water, and makes the continuous operation of pump housing energy, so design for transporting general industrial water, simple to operate, simple in structure, suction pump easy for installation necessitates.
The model utility content
In order to overcome existing suction pump dismounting inconvenience, noise is large, unreasonable structure, and basis is novel to provide a kind of installation simple, operates steadily the coaxial suction pump that service behaviour is strong.
The utility model is achieved through the following technical solutions:
Coaxial suction pump, comprise the pump housing, motor, waterleaf, rotatingshaft, volute casing, water intake and water outlet, described motor directly is connected with an end of described rotatingshaft, and described motor and described rotatingshaft are horizontally disposed with, the other end of rotatingshaft arranges described waterleaf, the position of described waterleaf is fixed by the waterleaf screw, described waterleaf is positioned at described volute casing, described waterleaf vertically arranges, the central axes at the central axis of described water intake and rotatingshaft place, the central axis of described water outlet is vertical with horizontal line, and the central axis of described water outlet overlaps with the vertical axis at waterleaf place.
Described water outlet is connected by pipeline with waterleaf, and described pipeline and volute casing are tangent.The cross-section area of described pipeline is from enlarging gradually near an end of the waterleaf end to water outlet.Described waterleaf is provided with round structure in the side near water intake, and the center of described round structure is on the central axis of rotatingshaft, and the bore of described round structure is identical with the bore of water intake.Described volute casing vertically arranges, and the vertical central axis of described volute casing and the central axes of described water outlet.The bore of described water outlet and water intake is identical.Described motor is the squirrel-cage shaped motor.
The beneficial effects of the utility model are: described pump body structure is compact, can increase work efficiency, because pipeline is coaxial with waterleaf, and level directly connects, and can build in addition the chamber of drawing water, and can keep stable flow and lift.
Description of drawings
Fig. 1 is section plan of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
Coaxial suction pump, comprise the pump housing 1, motor 2, waterleaf 3, rotatingshaft 4, volute casing 10, water intake 5 and water outlet 6, described motor 2 directly is connected with an end of described rotatingshaft 4, and described motor 2 is horizontally disposed with described rotatingshaft 4, the other end of rotatingshaft 4 arranges described waterleaf 3, the position of described waterleaf 3 is fixing by waterleaf screw 7, described waterleaf 3 is positioned at described volute casing 10, described waterleaf 3 vertically arranges, the central axes at the central axis of described water intake 5 and rotatingshaft 4 places, the central axis of described water outlet 6 is vertical with horizontal line, and the central axis of described water outlet 6 overlaps with the vertical axis at waterleaf 3 places.
Described water outlet 6 is connected by pipeline 8 with waterleaf 3, and described pipeline 8 is tangent with volute casing.The cross-section area of described pipeline 8 is from enlarging gradually near an end of waterleaf 3 end to water outlet 6.Described waterleaf 3 is provided with round structure 9 in the side near water intake 5, and the center of described round structure 9 is on the central axis of rotatingshaft 4, and the bore of described round structure 9 is identical with the bore of water intake 5.Utilize this structure, the effective part solid impurity in the filtering liquid, described volute casing 10 vertically arranges, and the central axes of the vertical central axis of described volute casing 10 and described water outlet 6.Described water outlet 6 is identical with the bore of water intake 5.Described motor 2 is the squirrel-cage shaped motor.Can realize the work of high efficiency smooth.
Rotatingshaft 4 is directly driven by motor 2, liquid enters in the pump via water intake 5, first filling liquid before starting, waterleaf 3 high speed rotating, near the waterleaf 3 liquid also runs up, under the effect of centrifugal force, dished out from waterleaf 3 centers outer rim and obtain energy of liquid, liquid enters volute casing 10 with energy at a high speed, because runner enlarges gradually in the outlet conduit 8, thereby liquid velocity reduces, portion of energy is transformed into static energy, flows out with high pressure at last, in the time of work, liquid is formed centrally certain negative pressure in the waterleaf 3, so can be pressed in the waterleaf 3 continuously.
The above describes this novel specific embodiment in detail.But should be appreciated that this novel mode of execution is not limited in above-described embodiment, the description of above-described embodiment only is used for helping to understand this novel spirit.Under this novel spirit that discloses, to these novel various variation examples of doing, all fall in this novel scope.
