The corrosion-resistant water-ring vacuum pump is characterized in that the pump body, the pump cover and the disc are all made from composite materials taking polyphenyl thioether as the base material. The corrosion-resistant water-ring vacuum pump disclosed by the invention has the advantages that the corrosion resistance and abrasion resistance of the pump are greatly enhanced, the weight and operation noise of the pump are greatly reduced, and the service life of the pump is prolonged.
Description
Technical field
The invention belongs to pump field, be specifically related to a kind of Nash hytor.
Background technique
Nash hytor is used as self-priming water pump at first, then gradually for many industrial departments such as oil, chemical industry, machinery, mine, light industry, medicine and food.In industrial many manufacturing processs, as vacuum filtration, vacuum water diversion, vacuum feeding, vacuum evaporation, Vacuum Concentration, vacuum conditioning and vacuum outgas etc., Nash hytor is widely used.Nash hytor run on the market at present, all adopt metallic material manufacture, owing to containing number of chemical element in water, so workpiece suffers serious various corrosion, comprise aqueous corrosion, dielectric corrosion, electrochemical corrosion and the most fatal cavitation erosion, cause its workpiece efficiency low, general about 30%, can reach 50% preferably, another maintenance is frequent, changes component phenomenon very common.
Temperature is also very large on the impact of the Nash hytor that metal manufactures.Based on the running principle of Nash hytor, strict to the requirement of temperature, moreover the part fits precision of Nash hytor is higher.Therefore, in equipment running process, when occurring self machinery or electric reason and elevate the temperature or occur that the temperature of suction gas uprises, cause the cooperation of parts tight by making metal parts heat rise, often there is catastrophe failure in working pump, even scraps.
Due to Nash hytor operational condition caused by, the Nash hytor of metallic material manufacture highlights serious not corrosion-resistant, a series of insoluble problem such as not wear-resistant, the life-span is short.
Summary of the invention
In order to solve the above-mentioned technical problem that Nash hytor produces, the invention provides a kind of anti-corrosive water circular type vacuum pump being base-material with polyphenylene thioether, corrosion-resistant, wear-resistant.
The technical solution adopted for the present invention to solve the technical problems is: invent a kind of anti-corrosive water circular type vacuum pump being base-material with polyphenylene thioether, comprise the pump housing, pump cover, disk, it is characterized in that the pump housing, pump cover and disk are made by the composite material being base-material with polyphenylene thioether.
In the present invention, in described composite material, add glass fibre, by the content of mass parts glass fibre between 15%-40%; Carbon fiber is added, by the content of mass parts carbon fiber between 6%-10% in composite material; Also comprise water ring rotor in the present invention, the composite material that water ring rotor is base-material by polyphenylene thioether is made.
Compared with prior art, the invention has the beneficial effects as follows:
1. owing to forming the critical piece pump housing of Nash hytor, pump cover and disk, by with polyphenylene thioether for base-material and the glass fibre adding enhancing make, increase density, polyphenylene thioether has the feature of high strength, high rigidity and dimensional stability, rigidity is also good under conditions of high humidity, substantially increases the corrosion-resistant of vacuum pump and abrasion resistance properties.
2. owing to adding carbon fiber, the toughness of critical piece can be improved.Because the molecular density of this composite material is to temperature expansion
Coefficient is less, and can not produce the problem of the bad pump that rises.
3., by the change to component materials, greatly reduce the weight of pump and run noise, decreasing maintenance, add the working efficiency of pump.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Mark in figure: 1, pump cover; 2, disk; 3, water ring rotor; 4, the pump housing; 5, motor.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail.
Shown in Fig. 1 is the STRUCTURE DECOMPOSITION figure of ordinary water ring vacuum pumps, forms primarily of pump cover 1, disk 2, water ring rotor 3, the pump housing 4 and motor 5.In the present invention, the pump housing 4, pump cover 1 and disk 2 are made by the composite material being base-material with polyphenylene thioether.Having added the glass fibre of humidification in composite material, can be 15%, 25%, 40% etc. by the content of mass parts glass fibre.Can also add carbon fiber in composite material, can be 6%, 8%, 10% etc. by the content of mass parts carbon fiber.The composite material that water ring rotor 3 is base-material by polyphenylene thioether is made.
In the present invention, the base-material manufacturing the pump housing, pump cover, disk and water ring rotor adopts polyphenylene thioether, polyphenylene thioether has high strength, high rigidity and dimensional stability, and rigidity is also good under conditions of high humidity, and has outstanding fatigue performance and creep-resistant property; Moisture absorption, oil absorption, molding shrinkage and linear expansion coeffcient are all very little; There is good high resistivity and low-k, even if still keep good electrical insulation capability under hot and humid; Have excellent chemical-resistant stability, decay resistance is almost suitable with teflon, and these performances of polyphenylene thioether, compared with metallic material, well solve corrosion-resistant, wear-resistant, inefficiency, the frequent problem changing component of vacuum pump.
The present invention adopts polyphenylene thioether to be that base-material is equipped with multiple macromolecular material and fiber becomes modified composite material, and composite density is increased to 1.60-1.68g/cm
3the wear-resisting property of vacuum pump is improved very large, modified composite material excellent heat resistance after glass fiber reinforcement, 260 DEG C can be reached, solve metal parts heat rise and cause the untight problem of the cooperation of parts, make use of the advantage that composite weight is light, reduce operating noise, vacuum pump is run more stable.So Nash hytor prepared by the composite material utilizing polyphenylene thioether to add glass fibre for base material, it is the desirable substitution material overcoming the Nash hytor all defect that metallic material manufactures.
The above is only preferred embodiment of the present invention, and be not restriction the present invention being made to other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the Equivalent embodiments of equivalent variations.But everyly do not depart from technical solution of the present invention content, any simple modification, equivalent variations and the remodeling done above embodiment according to technical spirit of the present invention, still belong to the protection domain of technical solution of the present invention.
