Abstract
The invention relates to a wear-resisting impact-resisting jet vacuum pump and belongs to the technical field of radial flow non-variable volume fluid pumps. The wear-resisting impact-resisting jet vacuum pump comprises a submerged pump, a jet device and a vacuum tank. The submerged pump comprises a pump body, a motor and an impeller. The pump body is provided with a pump cover. The pump cover is provided with a water outlet pipe. The jet flow liquid inlet end of the jet device communicates with a water outlet of the submerged pump. The air inlet end of the jet device communicates with an outlet of the vacuum tank. The water outlet pipe on the pump cover comprises a round-tube-shaped metal base plate and ceramic bodies. Mounting holes penetrating through the outer cylindrical surface and the inner cylindrical surface of the metal base plate are formed in the metal base plate. The outer cylindrical surface and the inner cylindrical surface of the metal base plate are coated with casting layers correspondingly. The ceramic bodies are arranged in the casting layers and the mounting holes and are located at one end of the outer cylindrical surface of the metal base plate and made into a honeycomb shape. By the adoption of the wear-resisting impact-resisting jet vacuum pump, the ceramic bodies can be firmly fixed to the water outlet pipe of the submerged pump, so that the interior of the water outlet pipe on the pump cover is resistant to wear and impact, and the cost is low.
Description
Technical field
The present invention relates to a kind of immersible pump, belong to Radial Flow non-positive-displacement fluid pump technical field.
Background technology
Jet vacuum pump is to utilize machinery, physics, chemistry or the method for materialization, produces within the enclosed space, improves and ties up
Hold the device of vacuum.Typically be made up of immersible pump, jet vacuum pump, pump box three part, be widely used in oil, chemical industry, food,
The reduction vaporization of the industries such as pharmacy, light industry, environmental protection, crystallize, distill, be dried, decolour, deodorize, among the technique such as vacuum handling.
Immersible pump generally comprises the pump housing, motor, impeller;Water inlet, outlet it is provided with on the described pump housing；Electric motor starting band
Dynamic wheel rotation, drives water to enter from water inlet, then discharges from outlet, and water stream channel is the hollow bulb by pump body
Divide the passage formed.
Immersible pump is conveying liquid or the machinery making fluid pressurization.Mechanical energy or other external energies of prime mover are passed by it
Give liquid, make liquid energy increase, be mainly used to carry liquid and include 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, the service life of immersible pump is frequently not to be depended on
Motor quality and be depending on water pump and cross 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, uses low cost, seeks raising submersible pump and crosses the approach of stream part anti-sand abrasion performance, is a class of significant
Topic.
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 resistance to punching
The wear and shock-resistant jet vacuum pump hit.
The present invention solves that the technical scheme that above-mentioned technical problem proposes is: a kind of wear and shock-resistant jet vacuum pump, bag
Including immersible pump, ejector and vacuum tank, described immersible pump includes the pump housing, the motor being located in the pump housing and impeller, on the described pump housing
Pump cover is set, described pump cover is shaped with outlet pipe, described motor output shaft stretch out down and with impeller middle spindle be connected, described in penetrate
The injection liquid entrance point of stream device connects the outlet of described immersible pump, and the inlet port connection vacuum tank of described ejector goes out
Mouthful, the outlet pipe on described pump cover includes metal basal board and the ceramic body of tubular, and described metal basal board is shaped with its cylindrical through
Cylinder and the installing hole of inner cylinder face, described metal basal board external cylindrical surface and inner cylinder face are covered with cast layer, described pottery
Body is located in cast layer and installing hole, and described ceramic body is positioned at one end of described metal basal board external cylindrical surface and is made as cellular.
The present invention uses technique scheme to provide the benefit that: 1) owing to the outlet pipe on pump cover includes the gold of tubular
Belong to substrate and ceramic body, be shaped with its external cylindrical surface through and the installing hole of inner cylinder face by metal basal board, when producing water pipe,
Can be located on installing hole by ceramic body, the cast layer outside outlet pipe flows into inside outlet pipe by installing hole, by ceramic body
Fixedly secure on the outlet pipe of tubular so that outlet pipe is internal wear-resisting, low cost；2) it is positioned at metal basal board due to ceramic body
One end of external cylindrical surface is made as cellular so that outlet pipe impact resistance.
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 for Fe and is inevitably mingled with unit
Element.
Antimony: Sb fusing point 630 DEG C, it is to promote that pearlite forms element, to thin-section casting, can make the complete pearly-lustre of tissue
Body, and atomic to different wall matrix difference, sectional sensitivity significantly reduces.There is the bigger latent heat of fusion, add
0.04～0.08% Sb of content, hence it is evident that refinement macrostructure, form temperature fluctuation at part microcell, cause indigenous graphite core
The heart, can refine graphite.
The present invention uses technique scheme to provide the benefit that: by adding Sb and Cu of trace in cast layer, raw
Producing with low cost, 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 corresponding described installation
The conic ceramic body in hole.
