A kind of abrasion-proof slurry pump
Technical field
The utility model relates to solid-liquid conveying equipment field, particularly relates to a kind of abrasion-proof slurry pump.
Background technique
In smelting industry, the medium of carrying in ore pulp production procedure comprises 30% ~ 40% granule ore pulp, and the capital equipment of carrying is slag stock pump, and it is the centrifugal vane pump of pumping two-phase solid-liquid fluid.But existing slag stock pump is owing to carrying above-mentioned hard and corrosive raw material, most of forward and backward backplates, impeller, the pump housing only have 7 day working life.When its work, rotate in pump chamber by the impeller that rotarily drives of pump shaft, fluid is sucked from the import of impeller, along the volute chamber that radially enters sheath of impeller, finally discharge from the outlet of sheath.In this working procedure, the solid particle in fluid is the flow-passing surface of heavy wear flow passage part not only, and can flow between original structure impeller outlet end and forward and backward backplate, causes wearing and tearing to accelerate.Impeller inlet adopts right angle contact face, and solid particle easily enters in apron plate, and apron plate is caused to wearing and tearing.In addition, due to pump chamber fluid pressure difference, fluid can flow from zone of high pressure to low pressure area and form eddy current.Under the double action of solid particle and eddy current, the wearing and tearing of flow passage part are very serious.Therefore, flow passage part generally all adopts the antifriction alloy material that cost is higher.However, the working life of flow passage part is still relatively short, changes also more frequent.Like this, not only need to consume very large manpower and materials, but also the maintenance of will often stopping, replacing accessory cause manufacturing efficiency low.Therefore, for avoiding above-mentioned technical problem, must provide a kind of abrasion-proof slurry pump with new structure, to overcome described defect of the prior art.
Summary of the invention
The purpose of this utility model will provide a kind of abrasion-proof slurry pump exactly, and it can solve short, the problem such as efficiency is low of existing existing life-span of slag stock pump.
The purpose of this utility model is achieved in that a kind of abrasion-proof slurry pump, comprises the front pump housing, impeller, the rear pump housing, pump shaft, bracket, it is characterized in that: on described bracket, pump shaft is installed; On described pump shaft, be disposed with from left to right impeller, sub-propeller, the sealing of Double End machine for the assembly of unit load tool; Between described impeller and the front pump housing, be provided with apron plate, between impeller and the rear pump housing, be provided with rear backplate; Between the described front pump housing and pump housing import, be provided with the anti-cut water that revolves.
Described in the utility modelly anti-revolving cut water, is to adopt on flange, to weld a cut water plate, and its cross section be ellipse.
Between apron plate described in the utility model and impeller inlet face, it is angle contacting face.
Apron plate described in the utility model and rear backplate are all arranged to L-type at impeller outlet end.
The pump chamber of apron plate described in the utility model, rear backplate and the sealing of sheath composition.
Between rear backplate described in the utility model and the rear pump housing, be provided with pump chamber Rinsing unit.
In Double End machine for the assembly of unit load tool sealing described in the utility model, be provided with mechanical seal rinsing device.
The utility model has improved the wear resistance of flow passage part, and the life-span of forward and backward backplate, impeller, the pump housing is improved, thereby improves the working life of pump, has reduced maintenance frequency, has reduced cost of production.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
In figure: 1, pump housing import; 2, the anti-cut water that revolves; 3, the front pump housing; 4, apron plate; 5, angle contacting face; 6, impeller; 7, sheath; 8, rear backplate; 9, the rear pump housing; 10, sub-propeller; 11, pump chamber Rinsing unit; 12, Double End machine for the assembly of unit load tool sealing; 13, mechanical seal rinsing device; 14, pump shaft; 15, bracket.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
With reference to accompanying drawing, a kind of abrasion-proof slurry pump, comprises the front pump housing 3, impeller 6, the rear pump housing 9, pump shaft 14, bracket 15, it is characterized in that: on described bracket 15, pump shaft 14 is installed; On described pump shaft 14, be disposed with from left to right impeller 6, sub-propeller 10, Double End machine for the assembly of unit load tool sealing 12; Between described impeller 6 and the front pump housing 3, be provided with apron plate 4, between impeller 6 and the rear pump housing 9, be provided with rear backplate 8; Between the described front pump housing 3 and pump housing import 1, be provided with the anti-cut water 2 that revolves.The described anti-cut water 2 that revolves, is to adopt on flange, to weld a cut water plate, and its cross section is oval.Between described apron plate 4 and impeller 6 inlet faces, it is angle contacting face 5.Described apron plate 4 is all arranged to L-type with rear backplate 8 at impeller outlet end.Described apron plate 4, rear backplate 8 form with sheath 7 pump chamber sealing.Between described rear backplate 8 and the rear pump housing 9, be provided with pump chamber Rinsing unit 11.In described Double End machine for the assembly of unit load tool sealing 12, be provided with mechanical seal rinsing device 13.When concrete enforcement, pump shaft is arranged on bracket, and impeller is fixed on pump shaft by scyewed joint, is made up of the pump chamber of sealing sheath, apron plate, rear backplate.The front pump housing and the rear pump housing are the peripheral components of pump chamber.1), adopt the streamlined anti-cut water that revolves in the inlet of pump, and the anti-cut water that revolves is to adopt on flange, to weld a cut water plate, and its cross section be ellipse.Because entering pump inlet meeting generation, mortar prewhirls very greatly, mortar easily enters between impeller and apron plate, forming internal vortex solid ore pulp is difficult for outside excavationg pump, make apron plate easy to wear, increase streamlined anti-revolving after cut water, eliminate eddy flow, can make slurries directly enter suction eye, improved the life-span of impeller and apron plate; 2), be angle contacting face between apron plate and impeller inlet face, and angle of inclination is consistent with main flow direction, prevents that particle from entering in apron plate, reduces apron plate wearing and tearing; 3), apron plate and rear backplate are all arranged to L-type choma structure at impeller outlet end, prevent from entering in the chamber of apron plate and rear backplate and impeller front and back blade because outlet high pressure makes slurry particles, and forming vortex wearing and tearing, the working life of having improved pump, more than increasing to half a year by original 7 days; 4), adopt Double End integrated mechanical sealing; and increase Rinsing unit; sparge water pressure is greater than the working pressure of pump; make mortar be difficult for entering in machine envelope; between rear backplate and the rear pump housing, increase pump chamber Rinsing unit in addition, before start and after shutting down, adopt high pressure clear water, mortar between rear backplate and impeller is gone out; in order to avoid after start mortar inside wear and tear after backplate, prevent that mortar from entering machine envelope.
