Description
Technical field
The invention belongs to pump field, be specifically related to a kind of water-ring vacuum pump.
Background technology
The water-ring vacuum pump run on our times, all adopts metal material manufacture.Water-ring vacuum pump is in running work, cut extremely serious with the situation of corrosion and prominent.Owing to water-ring vacuum pump adopts the form of water-stop, in equipment runs, the water height rotary motion in the pump housing can produce the effect of cutting water cutter, and the pump housing is produced linear incision, causes that the pump housing is scrapped owing to cutting the damage caused.Environment residing for water-ring vacuum pump, its workpiece also suffers from serious various corrosion, including aqueous corrosion, dielectric corrosion, electrochemical corrosion and the most fatal cavitation erosion.These corrosion, make the water-ring vacuum pump efficiency to parts quality of fit requirement is higher reduce, degradation, thus causing accelerating frequency of maintenance, the result of serious cavitation erosion can cause that pump is scrapped.
Temperature is also very big on the impact of the water-ring vacuum pump that metal manufactures.Based on the operation logic of water-ring vacuum pump, the requirement of temperature is strict, furthermore, the parts quality of fit of water-ring vacuum pump is higher.Therefore, in equipment running process, occur that the reason mechanically or electrically of self elevates the temperature or occurs when the temperature of suction gas uprises, metal parts thermal expansion will be made and cause that the cooperation of parts is closely.Such as shutdown inspection not in time, working barrel generation catastrophe failure can be made, so that scrapping.
Metal is due to Heavy Weight, and elastic modelling quantity is little, not only seriously corroded, and installs extremely inconvenient.
Caused by the operational condition of water-ring vacuum pump, the water-ring vacuum pump of metal material manufacture has highlighted serious, equipment inefficiency short weak to the burn into use and maintenance cycle, has installed a series of insoluble problems such as difficult, the life-span is short.
Summary of the invention
In order to solve the above-mentioned technical problem that water-ring vacuum pump produces, the present invention provides a kind of water-ring vacuum pump high temperature resistant, corrosion resistant, high temperature resistant, corrosion-resistant.
The technical solution adopted for the present invention to solve the technical problems is: a kind of high temperature resistant, anti-corrosive water circular type vacuum pump of invention, including the pump housing, pump cover, disk and impeller, it is characterised in that the pump housing, pump cover, disk and impeller are made by the composite formed with polyphenylene oxide resin, glass fibre, polystyrene, Masterbatch and antioxidant.

Glass fibre is the alkali-free glass fibre through processing, polystyrene is one or both the mixture in polystyrene or high-gloss high-impact polystyrene, antioxidant is four [β-(3,5-di-tert-butyl-hydroxy phenyl) propanoic acid] pentaerythritol ester, one or both mixture in three (2,4-di-tert-butyl-phenyl) phosphite ester.
Compared with prior art, the invention has the beneficial effects as follows:
Owing to constituting the critical piece pump housing of water-ring vacuum pump, pump cover, disk and impeller, the composite of polyphenylene oxide resin, glass fibre, polystyrene, Masterbatch and antioxidant composition is made, polyphenylene oxide resin has prominent physical and mechanical properties (including mechanical property, electrical property, hot property), excellent dimensional stability and weatherability, glass fibre is effectively increased the toughness of material, polystyrene has good mechanical properties, quality is hard, in rigidity, good chemical property, excellent electrical insulation capability, excellent optical property and the transparency；Owing to the molecular density of this composite is less to temperature expansion coefficient, the problem of the bad pump that rises without generation, it is easy to processing, by the change of component materials, greatly reduce the weight of pump and run noise, enhancing thermostability and dimensional stability, substantially prolongs the service life of pump.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Labelling in figure: 1, pump cover；2, disk；3, impeller；4, the pump housing；5, motor.
Embodiment one
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail.
Shown in Fig. 1 is the STRUCTURE DECOMPOSITION figure of light water ring vacuum pumps, is mainly made up of pump cover 1, disk 2, impeller 3, the pump housing 4 and motor 5.In the present invention, the pump housing 4, pump cover 1, disk 2 and impeller 3 are made by the composite formed with polyphenylene oxide resin, glass fibre, polystyrene, Masterbatch and antioxidant.Polystyrene adopts ordinary polystyrene or high-gloss high-impact polystyrene, it is also possible to adopt the mixture in ordinary polystyrene and high-gloss high-impact polystyrene.Antioxidant is four [β-(3,5-di-tert-butyl-hydroxy phenyl) propanoic acid] pentaerythritol ester or three (2,4-di-tert-butyl-phenyl) phosphite esters, or the mixture of these two kinds of materials.
Calculate by weight, specifically comprise polyphenylene oxide resin 40 parts, glass fibre 29 parts, polystyrene 30 parts, Masterbatch 0.5 part and antioxidant 0.5 part.
The present invention adopts polyphenylene oxide resin to be that base material is equipped with multiple macromolecular material and glass fibre, becomes modified composite material.Mould and the water-ring vacuum pump of technique manufacture of die casting thoroughly solves the serious problems that the water-ring vacuum pump of metal material manufacture occurs by changing.Modifiying by polyphenylene ether resin, compound becomes the composite of the intensity index reaching metal.Make full use of that the macromolecular material coefficient of frictions such as water polyphenylene ether resin, polystyrene are little and the poor big advantage of surface tension, overcome the phenomenon of the high pressure waterjet that water-ring vacuum pump produces at work, thus extending use time and the maintenance cycle of equipment, play composite material behavior corrosion-resistant, resistant to elevated temperatures.Make use of the advantage that composite weight is light, reduce operating noise, make operation more stable.Owing to the molecular density of this composite is less to temperature expansion coefficient, without producing to rise the problem of bad pump, so, water-ring vacuum pump prepared by the composite utilizing polyphenylene oxide resin, polystyrene, glass fibre, Masterbatch and antioxidant composition, is the desirable substitution material of the water-ring vacuum pump all defect overcoming metal material to manufacture.Global facility replacement stainless steel part is lightweight, and properties of product are stable, and anticorrosion effect is good, the best annealed process of product, and degree of crystallinity is high, and internal stress is little.
