Abstract

The invention relates to a screw rod type submersible pump with longer service life. The screw rod type submersible pump comprises a shell with a screw rod cavity and a group of screw rods arranged in the screw rod cavity; the lower end of each screw rod is connected with a water inlet channel; the upper end of each screw rod is connected with a water outlet channel; the front and rear ends of a screw rod shaft are supported by a bearing; the screw rod shaft is connected with a first motor through a transmission mechanism; a pressure regulation cavity is formed in the shell at the rear end of the screw rod shaft; the rear end of the screw rod shaft is inserted into the pressure regulation cavity; a sealing filler is embedded into an interval between the pressure regulation cavity and the screw rod shaft; and an annular groove is formed in the upper part of the screw rod cavity along the peripheral wall and communicates with the pressure regulation cavity through a pipeline. According to the screw rod type submersible pump, the water pressure at the front end of the screw rod pump is introduced into the rear end of the screw rod shaft, the screw rod shaft is pushed upward to overcome strong recoil force applied to the screw rods so as to enable the stress of the screw rod shaft to be more balanced, thus load and wear of the bearing are lowered, the service life of the submersible pump is prolonged, and guarantee is provided for further increasing the rotational speed of the screw rod pump.

Description

Wear and shock-resistant immersible pump
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
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 immersible pump hit.
The present invention solves that the technical scheme that above-mentioned technical problem proposes is: a kind of wear and shock-resistant immersible pump, including pump Body, the motor being located in the pump housing and impeller, the described pump housing arranges pump cover, and described pump cover is shaped with outlet pipe, and described motor is defeated Shaft stretches out down and is connected with impeller middle spindle, and described outlet pipe includes metal basal board and the ceramic body of tubular, described gold Belong to substrate and be shaped with its external cylindrical surface through and the installing hole of inner cylinder face, on described metal basal board external cylindrical surface and inner cylinder face all Being covered with cast layer, described ceramic body is located in cast layer and installing hole, and described ceramic body is positioned at described metal basal board external cylindrical surface One end be made as cellular.
The present invention uses technique scheme to provide the benefit that: 1) due to outlet pipe include tubular metal basal board and Ceramic body, is shaped with its external cylindrical surface through and the installing hole of inner cylinder face by metal basal board, when producing water pipe, can will make pottery Porcelain body is located on installing hole, and the cast layer outside outlet pipe is flowed into inside outlet pipe by installing hole, is fixedly secured by ceramic body On the outlet pipe of tubular so that outlet pipe is internal wear-resisting, low cost；2) it is positioned at metal basal board external cylindrical surface due to ceramic body One end be 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 pearlite of tissue Change, 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, can Refinement 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.
