Description
The application is divisional application, the application number 2014103717463 of original application, title：A kind of wear-resisting immersible pump, application
Day 2014.7.31.
Technical field
The present invention relates to a kind of immersible pump, belongs to radial flow non-positive-displacement fluid pump technical field.
Background technology
Immersible pump generally comprises the pump housing, motor, impeller;Water inlet, delivery port are provided with the pump housing；Electric motor starting band
Dynamic wheel rotation, drives water to enter from water inlet, is then discharged from delivery port, water stream channel is the hollow bulb by pump body
Divide the passage formed.
Immersible pump is the machinery for conveying liquid or being pressurized liquid.It passes the mechanical energy of prime mover or other external energies
Liquid is given, increases liquid energy, being mainly used to conveying liquid includes water, oil, acid ＆ alkali liquid, emulsion, suspended emulsion and liquid
Metal etc., it can also convey liquid, admixture of gas and the liquid containing suspended solids.
According to the applicant understood, when containing considerable silt particle in water, the service life of immersible pump is frequently not to depend on
Motor quality but depending on water pump excessively stream part (such as impeller, pump cover) resistance to sand wear ability.
For immersible pump, the synthesis of the cost of raw material and processing cost, being can not irrespective factor.Based on this
Condition, using low cost, the approach for improving the anti-sand abrasion performance of the another part of submersible pump excessively stream is sought, be a class of significant
Topic.
The content of the invention
The technical problem to be solved in the present invention is, in view of the shortcomings of the prior art, proposing a kind of inexpensive and wear-resisting wear-resisting
Immersible pump.
The present invention is to solve the technical scheme that above-mentioned technical problem proposes to be：A kind of wear-resisting immersible pump, including the pump housing, be located at
Motor and impeller in the pump housing, pump cover is set on the pump housing, outlet pipe is formed with the pump cover, the motor output shaft is down
Stretch out and be connected with impeller middle spindle, the outlet pipe includes the metal substrate and ceramic body of tubular, the metal substrate system
There is the mounting hole for penetrating its external cylindrical surface and inner cylinder face, be covered with casting on the metal substrate external cylindrical surface and inner cylinder face
Layer, the ceramic body is in cast layer and mounting hole.
It is of the invention to be using the beneficial effect of above-mentioned technical proposal：Because outlet pipe includes the metal substrate and pottery of tubular
Porcelain body, the mounting hole for penetrating its external cylindrical surface and inner cylinder face is formed with by metal substrate, can be by ceramics when making outlet pipe
On mounting hole, the cast layer outside outlet pipe is flowed into inside outlet pipe body by mounting hole, and ceramic body is fixedly secured
On the outlet pipe of tubular so that wear-resisting inside outlet pipe, cost is low.
The improvement of above-mentioned technical proposal is：Resin bed is scribbled in the cast layer.
The improvement of above-mentioned technical proposal is：The composition and mass percentage content that the 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 is inevitably mingled with member
Element.
Antimony:630 DEG C of Sb fusing points, it is to promote pearlite formation element, to thin-section casting, can make the complete pearlite of tissue
Change, and it is atomic to different wall matrix difference, sectional sensitivity significantly reduces.With the larger latent heat of fusion, 0.04 is added
The Sb of~0.08% content, hence it is evident that refinement macrostructure, microcell forms temperature fluctuation in part, causes indigenous graphite core, can be thin
Graphite.
It is of the invention to be using the beneficial effect of above-mentioned technical proposal：It is raw by adding micro Sb and Cu in cast layer
Produce that cost is cheap, and anti-wear performance is good so that the immersible pump service life that worked in water is obviously improved.
The improvement of above-mentioned technical proposal is：The mounting hole is taper mounting hole, and the ceramic body is the corresponding installation
The conic ceramic body in hole.
