Abstract
The invention relates to a wear-resisting submersible pump, and belongs to the technical field of radial-flowing non-positive-displacement type fluid pumps. The wear-resisting submersible pump comprises a pump body, a motor and an impeller, wherein the motor and the impeller are arranged in the pump body. The pump body is provided with a pump cover which is provided with a water outlet pipe, and an output shaft of the motor stretches downwards and is fixedly connected with a central shaft of the impeller. The water outlet pipe comprises a circular-pipe-shaped metal base plate and ceramic bodies, mounting holes penetrating through the outer cylindrical face and the inner cylindrical face of the metal base plate are formed in the metal base plate, the outer cylindrical face and the inner cylindrical face of the metal base plate are both covered with casting layers, and the ceramic bodies are located in the casting layers and the mounting holes. According to the wear-resisting submersible pump, the ceramic bodies can be firmly fixed to the water outlet pipe, so that the interior of the water outlet pipe is resistant to wear, and cost is low.
Description
Technical field
The present invention relates to a kind of immersible pump, belong to Radial Flow non-positive-displacement fluid pump technical field.
Background technology
Immersible pump generally comprises the pump housing, motor, impeller;The described pump housing is provided with water inlet, outlet；Electric motor starting impeller rotates, and drives water to enter from water inlet, then discharges from outlet, and water stream channel is the passage formed by the hollow space of pump body.
Immersible pump is conveying liquid or the machinery making fluid pressurization.It sends mechanical energy or other external energies of prime mover to liquid, liquid energy is made to increase, it is mainly used to carry liquid to include water, oil, acid & alkali liquid, emulsion, suspended emulsion and liquid metal etc., it is possible to conveying liquid, admixture of gas and the liquid containing suspended solids.
According to the applicant understood, time in water containing considerable silt particle, it is frequently not the service life of immersible pump and depends on that motor quality is depending on water pump and crosses the resistance to sand wear ability of stream part (such as impeller, pump cover).
Comprehensive for immersible pump, the cost of raw material and processing cost, is can not irrespective factor.Based on this condition, adopt low cost, seek raising submersible pump and cross the approach of the stream anti-sand abrasion performance of another part, be a problem of significant.
Summary of the invention
The technical problem to be solved in the present invention is, not enough for prior art, it is proposed to a kind of low cost and wear-resisting wear-resisting immersible pump.
The present invention solves that the technical scheme that above-mentioned technical problem proposes is: a kind of wear-resisting immersible pump, including the pump housing, the motor being located in the pump housing and impeller, the described pump housing arranges pump cover, described pump cover is shaped with outlet pipe, described motor output shaft stretches out down and is connected with impeller middle spindle, described outlet pipe includes metal basal board and the ceramic body of tubular, described metal basal board is shaped with the installing hole of its external cylindrical surface through and inner cylinder face, being covered with cast layer on described metal basal board external cylindrical surface and inner cylinder face, described ceramic body is located in cast layer and installing hole.
The present invention adopts technique scheme to provide the benefit that: owing to outlet pipe includes metal basal board and the ceramic body of tubular, the installing hole of its external cylindrical surface through and inner cylinder face it is shaped with by metal basal board, when producing water pipe, can ceramic body be located on installing hole, cast layer outside outlet pipe flows into inside outlet pipe by installing hole, ceramic body is fixedly secured on the outlet pipe of tubular so that outlet pipe is internal wear-resisting, and cost is low.
The improvement of technique scheme is: scribble resin bed in described cast layer.
The improvement of technique scheme is: composition and mass percentage content that described cast layer contains be: C:3.5～3.7%, Sb:0.04～0.08%, Mn:0.40～0.60%, Cu:0.30～0.40%, all the other are Fe and inevitable tramp element.
Antimony: Sb fusing point 630 DEG C, it is to promote pearlite forming element, to thin-section casting, can make the complete pearlite of tissue, and different wall matrix difference is atomic, and sectional sensitivity significantly reduces.There is the bigger latent heat of fusion, add the Sb of 0.04～0.08% content, hence it is evident that refinement macrostructure, rise and fall in part microcell formation temperature, cause indigenous graphite core, graphite can be refined.
The present invention adopts technique scheme to provide the benefit that: by adding Sb and the Cu of trace in cast layer, low production cost, and anti-wear performance is good so that immersible pump works in water and is obviously improved service life.
The improvement of technique scheme is: described installing hole is taper installing hole, and described ceramic body is the conic ceramic body of corresponding described installing hole.
