Abstract
The present invention relates to a kind of wear-resistant pipe, belong to engineering element technical field.This wear-resistant pipe includes metal basal board and the ceramic body of tubular, and metal basal board is shaped with its external cylindrical surface through and the installing hole of inner cylinder face, and metal basal board external cylindrical surface and inner cylinder face are covered with cast layer, and ceramic body is located in cast layer and installing hole.Ceramic body can be fixedly secured on metallic substrates by this wear-resistant pipe so that wear-resistant pipe is internal wear-resisting, low cost.
Description
Technical field
The present invention relates to a kind of wear-resistant pipe, belong to engineering element technical field.
Background technology
Immersible pump generally comprises the pump housing, motor, impeller;Water inlet, outlet it is provided with on the described pump housing；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 and includes 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).
For immersible pump, the cost of raw material and processing cost comprehensive, is can not irrespective factor.Based on this condition, use low cost, seek raising submersible pump and cross the approach of stream another part anti-sand abrasion performance, 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, proposes a kind of low cost and wear-resisting wear-resistant pipe.
The present invention solves that the technical scheme that above-mentioned technical problem proposes is: a kind of wear-resistant pipe, metal basal board and ceramic body including tubular, described metal basal board is shaped with its external cylindrical surface through and the installing hole of 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 uses technique scheme to provide the benefit that: owing to wear-resistant pipe includes metal basal board and the ceramic body of tubular, it is shaped with its external cylindrical surface through and the installing hole of inner cylinder face by metal basal board, it is covered with cast layer on metal basal board external cylindrical surface and inner cylinder face, ceramic body is located in cast layer and installing hole, when making wear-resistant pipe, ceramic body can 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 metal basal board of tubular, make wear-resistant pipe internal wear-resisting, low cost.
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%, remaining is Fe and inevitable tramp element.
Antimony: Sb fusing point 630 DEG C, it is to promote that pearlite forms element, to thin-section casting, can make the complete pearlite of tissue, and atomic to different wall matrix difference, and sectional sensitivity significantly reduces.There is the bigger latent heat of fusion, the addition 0.04～Sb of 0.08% content, hence it is evident that refinement macrostructure, form temperature fluctuation at part microcell, cause indigenous graphite core, graphite can be refined.
The present invention uses technique scheme to provide the benefit that: by adding Sb and 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.
Accompanying drawing explanation
The invention will be further described below in conjunction with the accompanying drawings:
Fig. 1 is the structural representation of embodiment of the present invention wear-resistant pipe.
Detailed description of the invention
Embodiment
The wear-resistant pipe of the present embodiment, as it is shown in figure 1, include metal basal board 1 and the ceramic body 2 of tubular.Metal basal board 1 is shaped with the installing hole 3 of its external cylindrical surface through and inner cylinder face, and metal basal board 1 external cylindrical surface and inner cylinder face are covered with cast layer 4, and ceramic body 2 is located in cast layer 4 and installing hole 3.
Resin bed 5 is scribbled in the cast layer 4 of the present embodiment.
Composition and mass percentage content that the cast layer 4 of the present embodiment contains be: C:3.5～3.7%, Sb:0.04～0.08%, Mn:0.40～0.60%, Cu:0.30～0.40%, remaining is Fe and inevitable tramp element.
The installing hole 3 of the present embodiment is taper installing hole, and ceramic body 2 is the conic ceramic body of corresponding installing hole 3.
The present invention is not limited to above-described embodiment.The technical scheme that all employing equivalents are formed, all falls within the protection domain of application claims.
