Description

A kind of wear and shock-resistant immersible pump
Technical field
The present invention relates to a kind of immersible pumps, belong to radial flow non-positive-displacement fluid pump technical field.
Background technology
Immersible pump generally comprises the pump housing, motor, impeller；Water inlet, water outlet are provided on the pump housing；Electric motor starting band Dynamic wheel rotation, drives water to enter from water inlet, is then discharged from water outlet, water stream channel is the hollow portion by pump body Divide the channel formed.
Immersible pump is the machinery for conveying liquid or liquid being made to be pressurized.It passes the mechanical energy of prime mover or other external energies Liquid is given, liquid energy is made to increase, is mainly used to convey liquid to include water, oil, acid ＆ alkali liquid, emulsion, suspended emulsion and liquid Metal etc. also can transport 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 overcurrent 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 cannot irrespective factor.It seeks and carries using low cost based on this condition The approach of the high anti-sand abrasion performance of submersible pump overcurrent part is a project of significant.
Invention content
The technical problem to be solved by the present invention is in view of the shortcomings of the prior art, propose a kind of inexpensive and wear-resisting and resistance to punching The wear and shock-resistant immersible pump hit.
The technical solution that the present invention proposes to solve above-mentioned technical problem is：A kind of wear and shock-resistant immersible pump, including pump Body, motor and impeller in the pump housing are arranged pump cover on the pump housing, outlet pipe are formed on the pump cover, the motor is defeated Shaft is stretched out and is connected with impeller middle spindle downward, and the outlet pipe includes the metal substrate and ceramic body of tubular, the gold Belong to the mounting hole that substrate is formed with perforation its external cylindrical surface and inner cylinder face, on the metal substrate external cylindrical surface and inner cylinder face It is covered with cast layer, the ceramic body is set in cast layer and mounting hole, and the ceramic body is located at the metal substrate external cylindrical surface One end be made as it is cellular.
The present invention is using the advantageous effect of above-mentioned technical proposal：1）Due to outlet pipe include tubular metal substrate and Ceramic body is formed with the mounting hole of perforation its external cylindrical surface and inner cylinder face by metal substrate, when making outlet pipe, can will make pottery Porcelain body is set on mounting hole, and the cast layer outside outlet pipe is flowed by mounting hole inside outlet pipe, and ceramic body is fixedly secured On the outlet pipe of tubular so that it is wear-resisting inside outlet pipe, it is at low cost；2）Since ceramic body is located at metal substrate external cylindrical surface One end be made as it is cellular so that outlet pipe impact resistance.
The improvement of above-mentioned technical proposal is：It is coated with resin layer in the cast layer.
The improvement of above-mentioned technical proposal is：The ingredient 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 that can make the complete pearly-lustre of tissue to thin-section casting Body, and it is atomic to different wall thickness matrix difference, sectional sensitivity significantly reduces.With the larger latent heat of fusion, it is added The Sb of 0.04~0.08% content, hence it is evident that refinement macrostructure, microcell forms temperature fluctuation in part, causes indigenous graphite core The heart can refine graphite.
The present invention is using the advantageous effect of above-mentioned technical proposal：It is raw by the way that micro Sb and Cu are added in cast layer Produce of low cost, wear-resisting property is good so that the immersible pump service life that works 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.
