Description
Technical Field
The utility model belongs to the technical field of submersible pumps, and particularly relates to an axial-flow submersible pump with a turbofan.
Background
As is known, a submersible axial flow pump is a pump which is operated by the action force of the blades of a rotary impeller on liquid to convey the liquid along the axial direction and submerge the liquid into water, before the pump is started, a suction pipe and the pump are filled with the liquid, the impeller rotates at a high speed after the pump is started, wherein the liquid rotates along with the blades, flies out of the impeller under the action of centrifugal force and is ejected out, and then flows out from a pump outlet drain pipe.
In addition, the axial-flow pump is used for extracting various liquids, a large amount of sludge, gravels, impurities and the like exist in the working environment of the axial-flow pump, direct extraction is not performed through filtration, the condition that blades on the impeller are broken frequently occurs in the working process, fine silt can enter the pump shaft in the working process to damage the shaft body, and the service life of the axial-flow pump is shortened.
Disclosure of Invention
Aiming at the problems in the prior art, the utility model provides an axial-flow submersible pump with a turbofan.
The present invention is thus achieved.
The utility model relates to an axial flow submersible pump with a turbofan, which comprises an axial flow pump shell, a water outlet pipe connected with the water outlet end of the axial flow pump shell, a submersible motor and an impeller, wherein the submersible motor is arranged in the axial flow pump shell and is connected with an external power supply and a control system through a lead; the water outlet end of the axial flow pump shell is connected with a reducing pipe, the small-diameter end of the reducing pipe is connected with the water inlet of the water outlet pipe, and the water inlet of the axial flow pump shell is provided with a filtering device.
Preferably, the filtering device is a filter screen.
The utility model has the advantages that:
the utility model has the advantages that: because the turbofan is additionally arranged in the axial flow pump shell close to the impeller, the guide of water flow is facilitated, and the efficiency of the axial flow submersible pump is improved; therefore, the normal and stable operation of the axial flow submersible pump is ensured, the maintenance cost is saved, and the axial flow submersible pump can operate more permanently, stably, efficiently and reliably.
In addition, because the filter device is arranged at the water inlet, the impeller and the turbofan blades in the axial flow pump main body are prevented from being damaged, and the service life of the submersible pump is prolonged.
Drawings
Fig. 1 is a schematic structural view of the present invention.
Fig. 2 is a sectional view of a-a portion of fig. 1.
Detailed Description
The utility model will be further explained with reference to the drawings.
An axial flow submersible pump with a turbofan comprises an axial flow pump housing 3, a water outlet pipe 9 connected with the water outlet end of the axial flow pump housing, a submersible motor and an impeller 4, wherein the submersible motor is arranged in the axial flow pump housing 3 and is connected with an external power supply and a control system through a lead, the submersible motor comprises a submersible motor rotating shaft 5 and a submersible motor rotor 6, the right side of the axial flow pump housing 3 is a water inlet 1, the left side of the axial flow pump housing 3 is a water outlet, the impeller 4 is arranged at the end part of the submersible motor rotating shaft 5, the axial flow pump housing 3 is internally provided with the turbofan 7 close to the impeller 4, the turbofan 7 consists of a turbofan blade 71 and a middle ring 72 connected with the turbofan blade, and the blade tip of the turbofan blade 71 is fixedly connected to the inner wall of the water outlet end of the axial flow pump housing 3 and is arranged at the left side close to the impeller 4; the water outlet end of the axial flow pump shell 3 is connected with a reducing pipe 8, the small diameter end of the reducing pipe 8 is connected with the water inlet of a water outlet pipe 9, and a filtering device 2 is arranged at the water inlet 1 of the axial flow pump shell 3.
The filtering device 2 is a filter screen, can be detached and cleaned at any time, and avoids damaging the impeller and the turbofan blade in the axial flow pump main body, thereby prolonging the service life of the submersible pump.
In the figure, 10 is a fixed frame, the turbofan can effectively restrain the rotating water flow passing through the impeller, reduce the friction between the fluid and the inner wall and prevent the rotating water flow from causing the vibration of the submersible pump.
In the description of the present invention, it is to be understood that the terms "inside", "left", "right", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
