Abstract
The utility model relates to an axial flow pump, which is used for the operations of irrigation and drainage and is composed of a pump body, a bent tube, a water outlet tube, etc. The bent tube of the pump can relatively rotate with the pump body to realize the regulation of the direction of the water outlet tube; a rotating connection tube with a slope moving flange is arranged between the bent tube and the water outlet tube to realize the regulation of the height of the water outlet tube. The pump overcomes the structural defect of the existing fixedly arranged type pump and use is very convenient; the utility model is suitable for carrying out the operation of flowing, irrigation and drainage in water network regions with complex landforms.
Description
The utility model relates to a kind of axial-flow pump that is used for the irrigation and drainage operation more, and it is made up of pump body, bend pipe, outlet pipe and bearing support.
The axial-flow pump that now is used for the irrigation and drainage operation all is the fixed installation formula, and promptly pump body, bend pipe, outlet pipe are assembled into one by flange by bolt, and bearing support is installed on the bend pipe, interfixes between them.After pump installs and fixes, also just fixed with the outlet pipe direction of the angled pump of pump body vertical centre axis.This axial-flow pump is applicable to fixedly irrigation and drainage operation occasion such as drainage and irrigation station very much, but situation for the irrigation and drainage operation of flowing, carry out disperseing the irrigation of field piece as the pump of installing aboard ship, the axial-flow pump of this fixed installation formula need be done some structural improvement, to improve the mobility of this axial-flow pump, strengthen its operation adaptability, specifically need make its outlet pipe height and direction adjustable.
The purpose of this utility model just is to overcome the deficiency of structure in the prior art, and a kind of height and adjustable axial-flow pump of direction of outlet pipe is provided.
The purpose of this utility model can reach by following measures: the periphery of the bottom of bend pipe is formed rotating the connection with the inner headed face of pump body upper pipe with little gap transition fit; The rotation of packing between bend pipe and outlet pipe is taken over, and forms the last pipeline and the following pipeline that rotate adapter and is linked together by active chuck by an inclined-plane flange; Bearing support is fixed on the pump body.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is a general structure schematic representation of the present utility model.
Fig. 2 is the structure partial sectional view of the rotating coupling part that bend pipe and pump body are formed in the utility model.
Fig. 3 is last pipeline during rotation of the present utility model is taken over or the structural representation that descends pipeline.
Fig. 4 is the A view of the utility model center Fig. 3.
The utility model comprises pump body (1), bend pipe (2), rotate take over, outlet pipe (5) and bearing support five parts, bearing support is fixed on the shell of pump body (not marking among the figure).The bottom of bend pipe has a convex shoulder (10), and convex shoulder is down for cooperating pipeline section (9).The inside of pump upper part of body is made up of two inner headed face steps (13), (15), and the outside is a flange plate (14).The periphery of cooperation pipeline section (9) is made little gap transition fit with inner headed face step (15) and is connected with the rotation of pump body to constitute bend pipe, and two fitting surfaces should have certain length to be connected with enough rigidity and intensity to guarantee the rotation that is constituted.For the purpose of sealing, between the convex shoulder (16) of convex shoulder (10) and two inner headed face steps (13), (15) centre, lay an abrasive rubber seal ring (12).Convex shoulder (10) is equipped with pressing plate (11) with the top of flange plate (14), and it can reach the axially movable purpose that limits between bend pipe and the pump body like this by being bolted on the flange plate (14).The rotation that identical caliber is installed between bend pipe and outlet pipe is taken over, constitute the last pipeline (6) of swing bend pipe and the two ends separately of following pipeline (3) and have a flange respectively, wherein the flange of an end (17) is fixed together by the flange of bolt and corresponding bend pipe or outlet pipe, the flange of the other end (7) takes the form of inclined plane, and its fitting surface becomes one not to be the angle at right angle with the pipeline center axis.Positive angle (Fig. 4) from the fitting surface of inclined-plane flange, the periphery of inclined-plane flange is a circle (18), the inner headed face of pipeline is an ellipse (19) on inclined-plane flange fitting surface, it two cooperates the inner headed face of pipeline to form discontinuous contact surface when relatively rotating for the two inclined-plane flanges that do not make pipeline (6) and following pipeline (3), the utility model is added correction to the longitudinal end position of oval (19), make it to study for a second time courses one has flunked and circle 18) concentric interior circle (20), so promptly solved the slick and sly unimpeded problem of pipe inner flow passage.(dash area among Fig. 4 (21) is the part of adding correction).Two inclined plane method your beautiful writings clamp with active chucks (8), and add rubber ring and seal.Handle (4) is changed hands in the activity that also is equipped with on the last pipeline (6).During work, swing bend pipe can adjust the direction of water pipe easily, when need adjust the height of water pipe, can make the last pipeline (6) and the following pipeline (3) that rotate adapter be in the state that to relatively rotate by active chuck (8), changing hands handle (4) by activity again makes pipeline turn over several angle with respect to following pipeline, owing to adopted the inclined-plane flange to connect, to produce a corresponding angle between the central shaft of last pipeline (6) and following pipeline (3), make the angle between the vertical centre axis of the central axis of outlet pipe and pump body change, thereby reach the purpose that changes the outlet pipe height, the direction of outlet pipe also will change this moment, can be regulated by swing bend pipe again.Experiment showed, when bend pipe both ends of the surface angle is 65 °, pipeline center's axis becomes 65 ° on the inclined-plane flange fitting surface in rotate taking over conveyance capacity the best of pump.
Compared with prior art, the utlity model has and to carry out the advantage of regulating to outlet pipe height and direction, uses very conveniently, can be adapted to the complex-terrain of dense waterway net region, a kind of desirable novel product for mobile irrigation and drainage operation of can yet be regarded as.
