Description
Technical field
The present invention relates to a kind of pump housing mechanical device, especially a kind of single-screw (single screw) pump device.
Background technology
Single-screw (single screw) pump belongs to rotator type positive displacement pump, it is with bushing intermeshing by screw rod in suction chamber and discharge chamber production
Raw volume changes to convey liquid.It is a kind of hermetic screw pump of internal messing, and main working parts are by with double end spiral shell
The single thread screw rod composition for revolving the bushing of cavity and being engaged in bore of stator.Usually described has twin-feed spiral cavity
Bushing and its support cylinder of outside be referred to as stator, the single thread screw rod is referred to as rotor.When passing through universal joint
When connecting shaft driving rotor makees planet gyration around stator center, just continuously engagement forms seal chamber to stator rotor pair, these are close
It is at the uniform velocity axially moved to the envelope chamber constancy of volume, pumped (conveying) medium is delivered to from suction side through stator rotor pair and extrudes end.
Single-screw (single screw) pump in environmental protection, shipping industry, petroleum industry, medicine, brewing industry, is built due to its superior characteristic
The fields such as industry, mining industry, chemical industry, paper industry are built to be widely used.Single-screw (single screw) pump can be divided into all-metal
Single-screw (single screw) pump and rubber bushing single-screw (single screw) pump.Stator coordinates with rotor clearance in all-metal screw pump, and working speed is high, causes to make
Use short life.All-metal screw pump is under the operating condition of the slow-speed of revolution or the liquid for pumping low viscosity, and leakage is serious, and pump pressure is low,
And whole-metal stator manufacture not easy to be processed, therefore be widely used not yet.Rubber lining in rubber bushing single-screw (single screw) pump
Set under the force effects such as tilting moment, extruding force, frictional force by deformation, abrasion, degumming is easily crowded flat, to cause single-screw (single screw) pump
Leakage is serious or fails, the service life of the rubber bushing single-screw (single screw) pump substantially reduced.
Nitrile rubber has good oil resistivity, wearability and heat resistance, is widely used for making because of the groups of CN containing polarized
Make screw rod of screw pump set (stator).With DP technology from past primary recovery gradually to secondary, tertiary recovery transition, oil well
Work condition environment is increasingly complex, often causes nitrile rubber premature failure containing sand etc. with high temperature, high pressure, strong corrosive media, height.
In order to adapt to the demand of complex hole condition, people are usually modified processing to nitrile rubber and increase substantially original performance or imparting
New performance, such as nitrile rubber and other plastics or blend rubber, the modification of nitrile rubber formula or surface modification etc..
Invention content

Work forms, and the composition of the nitrile rubber is calculated as by weight：100 parts of nitrile rubber, 25-45 parts of high wear-resistant carbon black, polyurethane
2-10 parts, 2-8 parts of polyvinyl chloride, 0.5-1 parts of stearic acid, 2-3 parts of o-phthalic acid dibutyl ester, 1-2 parts of sulphur, p-phenylenediamine class
0.5-1.5 parts of anti-aging agent, 4.6-12.3 parts of surface-modified nano filler material；The surface-modified nano filler material is to fill out nanometer
Charge is modified via large molecule surface modifier, and the weight ratio of nano-filled material and large molecule surface modifier is 79:1,
Wherein nano-filled material is by nanometer silicon carbide and nano composite oxide by weight 1:4 mix, the nano combined oxygen
Compound is by following general formula, SiaFebBacZndOX, wherein a=0.1-0.5, b=0.3-0.7, c=0.2-0.5, d=0.1-
0.3, X >=1.
The preparation method of the nano composite oxide, includes the following steps：
A) stoichiometric ratio shown in nano composite oxide general formula is pressed, by tetraethyl orthosilicate, ferric nitrate, barium nitrate, nitric acid
Zinc is dissolved in ethyl alcohol, is used as precursor solution；
B) under the pressure of 0.15Mpa, pass through 0.3m3The O of/h2Aerosol dispersion is carried out to precursor solution；
C) atomized drop is sprayed into flame reactor with the speed of 5ml/min, while is inversely passed through 0.76m3The H of/h2With
1m3The O of/h2And light, burning obtains nano composite oxide.
The large molecule surface modifier is methacrylic acid-acrylic acid butyl ester-acrylonitrile terpolymer.
The surface modifying method of the nano-filled material, includes the following steps：1 parts by weight large molecule surface modifier is added
Enter in 140 pbw acetones and form solution, the nano-filled material of 79 parts by weight is added in above-mentioned solution, in the protection of nitrogen atmosphere
