Description

Axial-flow pump convenient to maintain

Technical Field

The utility model relates to an axial-flow pump technical field especially relates to an axial-flow pump convenient to maintain.

Background

The axial flow pump has the characteristics of large flow and low lift, and is a hydraulic machine widely applied to production and living departments such as agricultural irrigation, urban water supply and the like. In recent years, with the rapid development of infrastructure business at home and abroad, the usage amount of the axial flow pump is also increased dramatically. When the axial flow pump is idle, microorganisms in water and the like are easy to invade, algae is easy to breed at the junction of water and air on the inner wall of the axial flow pump, the pump wall is corroded, even the axial flow pump is blocked, parts such as an impeller are always positioned under water under the general conditions, the junction of the water and the air is positioned above the impeller and below a water outlet, therefore, the service life of the axial flow pump needs to be prolonged by regularly cleaning the part of the inner wall in a conventional mode, but the difficulty of manual cleaning is high.

SUMMERY OF THE UTILITY MODEL

The utility model aims at changing the condition of breeding the alga to axial-flow pump inner wall water and air juncture, providing an axial-flow pump convenient to maintain.

In order to achieve the above object, the utility model relates to a technical scheme that axial-flow pump was taken convenient to maintain:

the utility model provides an axial-flow pump convenient to maintain, includes the suction tube, the play water return bend of being connected with the suction tube upper end and the cleaning device of clean suction tube inner wall, supreme impeller and the impeller of leading of having set gradually under down in the suction tube, the impeller is connected with the one end of pivot, the other end of pivot is vertical to be stretched out the play water return bend and be connected with gear motor, the pivot symmetry is provided with two sand grips, the sand grip sets up in the impeller top of leading, the sand grip both ends are provided with the stopper respectively, cleaning device sets up in the connecting rod of floating disc both sides and connects in the cleaning brush of connecting rod including sliding cup jointing in the floating disc of pivot, symmetry, floating disc and pivot junction be provided with sand grip. Floating plate sliding connection is in the pivot and rotates along with the pivot, stopper restriction floating plate sliding range, the floating plate floats in the surface of water, thereby the cleaning brush of being connected with the floating plate is located water and air juncture, when variable speed motor drive pivot low-speed rotation, be difficult to form negative pressure suction water flow in the suction pipe, the surface of water is comparatively steady, and the cleaning brush rotates and cleans the algae and the other adsorbed impurity that breed of suction pipe inner wall water and air juncture along with the floating plate under the pivot drives, when variable speed motor drive pivot high-speed rotation, horizontal plane constantly rises in the suction pipe, the floating plate rises until reaching spacing end under the rivers impact.

Furthermore, sleeves corresponding to the connecting rods are symmetrically arranged on two sides of the floating disc, the other end, connected with the cleaning brush, of the connecting rod is connected to the bottom of the sleeve in an inserting mode, the through hole is formed in the upper surface of the sleeve and located in the vertical range of the upper end limiting block, a protruding block matched with the through hole is arranged in the through hole, an inclined plane is arranged at the bottom of the protruding block towards the side of the rotating shaft, a second groove matched with the protruding block is formed in the top of the connecting rod, and a slope matched with the inclined plane is arranged in the second groove. When the axial-flow pump normally works, water flow is sucked from the suction pipe and discharged from the water outlet bent pipe, the floating disc rises until the upper end limiting block is influenced by the water flow, the limiting block abuts against the convex block to enable the inclined surface of the convex block to extrude the slope of the second groove, so that the connecting rod slides towards the direction of the rotating shaft, the cleaning brush is far away from the inner wall of the suction pipe, abrasion of the cleaning brush in long-term high-speed operation is reduced, and the service life of the cleaning brush is prolonged.

Furthermore, the floating disc is formed by splicing two same floating blocks. The two floating blocks are fastened through bolts, and are convenient to detach.

Further, the connecting rod is a hollow tube. Reducing the dead weight and increasing the buoyancy.

Further, the circumferential surface of the convex strip is provided with a ball. Reducing the friction force between the floating plate and the floating plate.

Compared with the prior art, the beneficial effects of the utility model are that: the structure is simple, and the cleaning can be finished by the low-speed rotation of the motor; the maintenance is convenient, and the maintenance and the cleaning can be finished by starting the motor regularly when the motor is idle; the cleaning device has the advantages that the cleaning device is used for cleaning the junction of water and air on the inner wall of the axial flow pump, the effect is obvious, and the service life of the axial flow pump is effectively prolonged.
