Abstract

The invention relates to an abrasion-resistant submersible pump, and belongs to the technical field of radial flowing invariable-capacity fluid pump. The abrasion-resistant submersible pump comprises a pump body, a motor and an impeller, wherein the motor and the impeller are arranged in the pump body. A pump cover is arranged on the pump body, and the pump cover is provided with a water outlet pipe. An output shaft of the motor stretches downwards and is fixedly connected with a central shaft of the impeller. The water outlet pipe comprises a circular-pipe-shaped metal substrate and ceramic bodies, the metal substrate is provided with mounting holes penetrating through the outer cylindrical surface and the inner cylindrical surface of the metal substrate, the outer cylindrical surface and the inner cylindrical surface of the metal substrate are respectively covered with a cast layer, and the ceramic bodies are arranged in the cast layers and the mounting holes. According to the abrasion-resistant submersible pump, the ceramic bodies can be firmly fixed to the water outlet pipe, and therefore the interior of the water outlet pipe is resistant to abrasion, and cost is low.

Description

Wear-resisting 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 conventionally; On the described pump housing, be provided with water intake, water outlet; Electric motor starting impeller is rotated, and drives water to enter from water intake, then discharges from water outlet, and flow channel is the passage forming by the hollow space of pump body.
Submersible 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, 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, 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) working life of submersible pump.
For submersible 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 Submerged Motor Pumps 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 submersible pump.
The present invention is that the technological scheme that solves the problems of the technologies described above proposition is: a kind of wear-resisting submersible 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 shape, described metal substrate is shaped with the mounting hole that connects its external cylindrical surface and inner cylindrical surface, on described metal substrate external cylindrical surface and inner cylindrical surface, be all covered with cast layer, described ceramic body is located in cast layer and mounting 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 shape, be shaped with the mounting hole that connects its external cylindrical surface and inner cylindrical surface by metal substrate, while producing water pipe, ceramic body can be located on mounting hole, the cast layer of outlet pipe outside flows into outlet pipe inside by mounting hole, ceramic body is fixedly secured on the outlet pipe of tubular shape, make outlet pipe inside wear-resisting, cost is low.
The improvement of technique scheme is: in described cast layer, scribble 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%, 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 castings, 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 macroscopic structure, 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, wear-resisting property is good, submersible pump is worked in water and improve obviously working life.
The improvement of technique scheme is: described mounting hole is taper mounting hole, and described ceramic body is the taper ceramic body of corresponding described mounting hole.
