Abstract
The utility model discloses a corrosion -resistant magnetic drive pump pump shaft, be in including hollow metal -cored and cladding metal -cored outer coating, the coating includes polyether ether ketone cellosilk and the carbon fiber that has the silica coating, the utility model discloses a have polyether ether ketone's coating, can increase substantially the life of bearing, under bearing the great operational environment with the temperature variation of pressure, in can guaranteeing that corrosive medium is unable and getting into the pump shaft, guaranteed the intensity and the rigidity of pump shaft to have good economic benefits.
Description
Technical field
The utility model belongs to magnetic drive pump pump shaft design field, is specifically related to a kind of corrosion-resistant magnetic drive pump pump shaft.
Background technique
Magnetic drive pump is hermetically sealed owing to having, No leakage, the feature such as corrosion-resistant, current application area is more and more wider, especially at chemical field, often in order to carry chemical liquid, simultaneously owing to carrying chemical liquid for a long time, working life considerable influence is brought to each parts of magnetic drive pump contact corrosion liquid, especially the pump shaft of critical component, operationally bearing strength is very large, temperature is higher, the pump shaft intensity simultaneously meeting High Nickel Steel again can meet the demands, but due to work under bad environment, working life is very short, become the life-span short slab of each parts in magnetic drive pump, and change pump shaft and not only increase director costs, the more important thing is and have impact on production process, usually to experience to shut down several times between each overhaul and change pump shaft, indirect economic loss is very large.
Therefore, need a kind of new technological scheme to solve the problem.
Model utility content
Model utility object: for above-mentioned prior art Problems existing and deficiency, the purpose of this utility model is to provide a kind of corrosion-resistant magnetic drive pump pump shaft.
Technological scheme: the utility model discloses a kind of corrosion-resistant magnetic drive pump pump shaft, comprise the metal-cored of hollow and be coated on described metal-cored outer clad, described clad comprises polyetheretherketonefiber fiber silk and the carbon fiber with silica dioxide coating, and namely polyetheretherketonefiber fiber silk and the carbon fiber with silica dioxide coating form clad of the present utility model jointly.
Polyether-ether-ketone has the physicochemical characteristics such as high temperature resistant, chemical resistance corrosion, has stronger rigidity and flexibility, particularly very outstanding to the fatigue resistance under alternating stress, and has superior wear resistance.
As further optimization of the present utility model, between metal-cored and clad described in the utility model, be provided with polyimide resin coating.
As further optimization of the present utility model, be described in the utility modelly metal-coredly provided with plup inlet, described plup inlet aperture is 3.5mm.
As further optimization of the present utility model, metal-cored internal surface described in the utility model is also provided with clad.
Beneficial effect: the utility model compared with prior art, have the following advantages: the utility model adopts the clad with polyether-ether-ketone, the working life of bearing can be increased substantially, under the working environment bearing the comparatively large and temperature variation of pressure, can ensure that aggressive medium cannot enter in pump shaft, ensure that the strength and stiffness of pump shaft, there is good economic benefit.
