Description

Wear-resisting immersible pump
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 comprises the pump housing, motor, impeller conventionally; On the described pump housing, be provided with water inlet, delivery port; Electric motor starting impeller is rotated, and drives water to enter from water inlet, then discharges from delivery port, and water stream channel is the passage forming by the hollow space of pump body.
Immersible pump is the machinery of carrying liquid or making liquid supercharging. It sends the mechanical energy of prime mover or other external energies to liquid, liquid energy is increased, be mainly used to carry liquid to comprise water, oil, acid & alkali liquid, emulsion, suspended emulsion and liquid metal etc., also can carry liquid, admixture of gas and the liquid containing suspended solids.
According to the applicant understood, contain considerable silt particle in water time, be not often to depend on motor quality but the resistance to sand wear ability that depends on water pump overcurrent part (as impeller, pump cover) service life of immersible pump.
For immersible pump, the cost of raw material and processing cost comprehensive, is can not irrespective factor. Based on this condition, adopt low cost, seek the approach that improves the anti-sand abrasion performance of the another part of submersible pump overcurrent, be a problem of significant.
Summary of the invention
The technical problem to be solved in the present invention is, for prior art deficiency, to propose a kind of low cost and wear-resisting wear-resisting immersible pump.
The present invention is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of wear-resisting immersible pump, comprise the pump housing, be located at motor and impeller in the pump housing, on the described pump housing, pump cover is set, on described pump cover, be shaped with outlet pipe, described motor output shaft stretches out down and is connected with impeller middle spindle, described outlet pipe comprises metal substrate and the ceramic body of tubular, described metal substrate is shaped with the installing hole that connects its external cylindrical surface and inner cylinder face, on described metal substrate external cylindrical surface and inner cylinder face, be all covered with cast layer, described ceramic body is located in cast layer and installing hole.
The present invention adopts the beneficial effect of technique scheme to be: because outlet pipe comprises metal substrate and the ceramic body of tubular, be shaped with the installing hole that connects its external cylindrical surface and inner cylinder face by metal substrate, while producing water pipe, ceramic body can be located on installing hole, the cast layer of outlet pipe outside flows into outlet pipe inside by installing hole, ceramic body is fixedly secured on the outlet pipe of tubular, make outlet pipe inside wear-resisting, cost is low.
The improvement of technique scheme is: in described cast layer, scribble resin bed.
The improvement of technique scheme is: the composition that described cast layer contains and mass percentage content are: C:3.5～3.7%, and 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: 630 DEG C of Sb fusing points, it is to promote pearlite forming element, to thin-section casting, can make to organize complete pearlite, and atomic to different wall matrix difference, sectional sensitivity obviously reduces. Have the larger latent heat of fusion, add the Sb of 0.04～0.08% content, obviously refinement macrostructure, rises and falls in part microcell formation temperature, causes indigenous graphite core, can refinement graphite.
The present invention adopts the beneficial effect of technique scheme to be: by add micro-Sb and Cu in cast layer, and low production cost, anti-wear performance is good, immersible pump is worked in water and improve obviously service life.
The improvement of technique scheme is: described installing hole is taper installing hole, and described ceramic body is the taper ceramic body of corresponding described installing hole.
