Description

Wear and shock-resistant submersible pump
Technical field
The present invention relates to a kind of submersible pump, belong to Radial Flow non variable capacitance type fluid pump technical field.
Background technique
Submersible pump comprises the pump housing, motor, impeller usually; The described pump housing is provided with water intake, water outlet; Electric motor starting impeller is rotated, and drive water to enter from water intake, then discharge from water outlet, flow channel is the passage formed by the hollow space of pump body.
Submersible pump is conveying liquid or the machinery making fluid pressurization.It sends the mechanical energy of prime mover or other external energies to liquid, liquid energy is increased, be mainly used to conveying liquid and comprise water, oil, acid & alkali liquid, emulsified liquid, suspended emulsion and liquid metal etc., also can carry liquid, gaseous mixture and the liquid containing suspended solids.
According to the applicant understood, time in water containing considerable silt particle, the working life of submersible pump is not often the resistance to sand wear ability depending on motor quality but depend on water pump overcurrent part (as impeller, pump cover).
For submersible pump, the cost of raw material and processing cost comprehensive is can not irrespective factor.Based on this condition, adopt low cost, seeking the approach improving the anti-sand abrasion performance of the another part of Submerged Motor Pumps overcurrent, is 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 and impact-resistant wear and shock-resistant submersible pump.
The present invention is the technological scheme solving the problems of the technologies described above proposition: a kind of wear and shock-resistant submersible pump, comprise the pump housing, be located at the motor 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 comprises metal substrate and the ceramic body of tubular shape, described metal substrate is shaped with the mounting hole of its external cylindrical surface through and inner cylindrical surface, described metal substrate external cylindrical surface and inner cylindrical surface are all covered with cast layer, described ceramic body is located in cast layer and mounting hole, one end that described ceramic body is positioned at described metal substrate external cylindrical surface is made as cellular.
The present invention adopts the beneficial effect of technique scheme to be: 1) because outlet pipe comprises metal substrate and the ceramic body of tubular shape, the mounting hole of its external cylindrical surface through and inner cylindrical surface is shaped with by metal substrate, when producing water pipe, can ceramic body be located on mounting hole, the cast layer of outlet pipe outside flows into outlet pipe inside by mounting hole, fixedly secured on the outlet pipe of tubular shape by ceramic body, make outlet pipe inside wear-resisting, cost is low; 2) one end being positioned at metal substrate external cylindrical surface due to ceramic body is made as cellular, makes outlet pipe shock-resistant.
The improvement of technique scheme is: described cast layer scribbles resin layer.
The improvement of technique scheme is: the composition that described cast layer contains and mass percentage content are: C:3.5 ~ 3.7%, Sb:0.04 ~ 0.08%, Mn:0.40 ~ 0.60%, Cu:0.30 ~ 0.40%, and all the other are Fe and inevitable tramp element.
Antimony: Sb fusing point 630 DEG C, it promotes pearlite forming element, to thin section castings, can make the complete pearlite of tissue, and atomic to different wall matrix difference, and sectional sensitivity obviously reduces.There is the larger latent heat of fusion, add the Sb of 0.04 ~ 0.08% content, obvious refinement macroscopic structure, rise and fall in part microcell formation temperature, cause indigenous graphite core, can refinement graphite.
The present invention adopts the beneficial effect of technique scheme to be: by adding Sb and Cu of trace in cast layer, low production cost, wear-resisting property is good, submersible pump is worked in water and improves obviously working life.
The improvement of technique scheme is: described mounting hole is taper mounting hole, and described ceramic body is the conic ceramic body of corresponding described mounting hole.
