Description
Technical field
The utility model relates to a kind of rail vehicles with the nonmetal impeller of cooling blower.
Background technique
On rail vehicles, generally be the axial fan that adopts airfoil fan with cooling blower, and impeller is the critical component of axial-flow blower, its quality good or not is determining the quality of complete machine.All be to adopt cast aluminium alloy and other metallic material at present, through the method preparation of precision casting, some is but through being welded mostly.This being applied in metal draught fan impeller exists following defective on the rail vehicles: one, railway locomotive running environment is complicated, and through the weather of regular meeting's experience dust storm and rainwater, and the impeller corrosion-resistant that metallic material is made is easy to generate corrosion.Two, there is deadweight problem bigger than normal in the impeller of metallic material making, and blower fan can produce strenuous vibration and huge noise in running, causes fan operation unstable, and electric efficiency is low, poor working environment.Three, through the impeller quality less stable of casting and welding production, various castings and weld defects appear easily.Four, the impeller cost that adopts aluminum alloy to make is higher.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned defective, a kind of in light weight, vibration and noise is few, intensity is high and good resistance to chemical corrosion are provided, make simple, cost is low and the rail vehicles of long service life with the nonmetal impeller of cooling blower.
The technological scheme of the utility model: a kind of rail vehicles is with the nonmetal impeller of cooling blower; Comprise impeller and metal core wheel; Impeller comprises blade and wheel hub; It is characterized in that the blade of described impeller and the nonmetal monolithic construction that wheel hub is compression molding, described metal core wheel solidifies as a whole simultaneously as inserter and nonmetal impeller, and promptly the nonmetal blade of impeller, nonmetal wheel hub and metal core wheel are cured as an overall structure simultaneously;
Described impeller is provided with dust guard, and wheel hub outer ring one side of impeller is provided with the embedded nut that is used to install additional dust guard, and promptly dust guard is fixed on the impeller through the embedded nut on the wheel hub, in order to dustproof and waterproof; The nonmetal blade of described impeller and the surface of nonmetal wheel hub are provided with wear-resisting and water-fast ceramic coating.
Impeller bodies in the utility model (comprising impeller blade and wheel hub) adopts short fibre
The reinforced plastic global formation.Core wheel adopts cast iron materials, to strengthen the wear resistance of impeller and wheel shaft, in the nonmetallic material system, adds anti-static agent and fire retardant, improves the Security of blower fan in locomotive operation.Nonmetal impeller preparation process adopts the short glass fiber reinforced epoxy, and die press technology for forming to raise the efficiency, is controlled cost.In nonmetal impeller surface brush ceramic coating, the wear resistance of reinforcing material and water resistence, the working life of prolongation impeller.
Impeller bodies adopts nonmetallic material to make, and optimizes the performance of improving special-purpose cooling blower through it, and above-mentioned blower fan defective is played a key effect, and the material system that is adopted comprises:
Adopt E-glass or S-glass as strengthening the body material, cut into the chopped strand of 5mm～10mm, evenly mix with resin matrix.In order to strengthen the bearing capacity of thickness direction, add the interior long fibre of 20mm～40mm length range of certain proportion (10%～30%) according to circumstances, evenly mix with chopped strand, form quasi-isotropic fibrofelt.
Adopt modified epoxy fat, it has, and technology capability is good, dimensional stability good, intensity is high, reach good resistance to chemical corrosion, can satisfy the many-sided performance requirement of product comprehensively.In addition, this type of forming materials time is short, have good manufacturing efficient, and cost is lower.
Core wheel adopts cast iron quality in the utility model, with the influence of the kinetic friction between minimizing machine shaft and the impeller to material; The process route of the utility model is: in mould, put into the metal core wheel in advance, then with the chopped strand molding material mould of at room temperature packing into, be heated to abundant fusion after pressurization fill all the other raw materials to expiring die cavity; After constant voltage is fixed, cool, keep briquetting pressure in the temperature-fall period; Finally demould and following process become final products.In the nonmetallic material system, add anti-static agent and fire retardant, improve the Security of blower fan in locomotive operation, to satisfy railway systems to of the requirement of nonmetallic material parts to flame retarding, Security.
The utility model has been simplified technology, controls cost, and has improved efficient, the quality of stable prod.Significantly reduce impeller weight, effectively reduce fan vibration and noise, improve blower fan stability and electric efficiency, improve working environment.Prolong product working life, and improved security of products and reliability.
