Description
Technical field
The invention belongs to the production methods of centrifuge rotor fan housing, and in particular to a kind of carbon fibre composite centrifuge water
The production method of the sub- fan housing of flat turn.
Background technique
Be conventionally used to the horizontal rotor fan housing of centrifuge, be generally made of aluminium alloy, weight is big, corrosion resistance compared with
Difference, intensity are lower, frequently alternately variation and circular flow are also easy to produce metal fatigue to high/low temperature.With constantly mentioning for centrifuge speed
High and the environment used and separate substance extension variation, aluminum alloy materials cannot fully meet requirement.
The prior art is usually that 3003 serial rustproof aluminium sheets is used to carry out by spinning or die forming blank, then to blank
Machining, thus the horizontal rotor fan housing of manufacture, since the horizontal rotor fan housing of rust-preventing aluminum alloy manufacture is anti-by 3003 series
The restriction (3003-O aluminium sheet yield strength 48MPa) of rust aluminium sheet material property, when centrifugal force is more than 4000 × g, it is possible to cause
Horizontal rotor fan housing slight deformation.When local centrifugal force is more than 8000 × g, horizontal rotor fan housing will go out under the action of the centrifugal force
Existing radial-draw deformation, the phenomenon that colliding, scrape with centrifugal chamber and crack, centrifuge is caused to damage.
Summary of the invention
The object of the present invention is to provide a kind of carbon fibre composite centrifugations light-weight, corrosion resistance is strong, intensity is high
The production method of machine horizontal rotor fan housing.
Realize the object of the invention the technical solution adopted is as follows:
The production method of carbon fibre composite centrifuge horizontal rotor fan housing provided by the invention, comprising the following steps:
Step 1. uses carbon fibre tow as raw material, and is impregnated with resin；Using aluminium sheet spinning or molding etc. at
Type method production technique rotor fan housing shape core green body carries out finishing to the green body, and the level for obtaining certain outer dimension turns
Sub- fan housing shape core；
The carbon fibre tow that step 2. is impregnated with resin is wound the surrounding of the horizontal rotor fan housing shape core, is formed
The enhancement layer of package；
The horizontal rotor fan housing shape core for being enclosed with enhancement layer is heating and curing by step 3. in an oven, obtains horizontal rotor wind
Cover shape core reinforcement, then polishing varnish is carried out to horizontal rotor fan housing shape core reinforcement outer profile, to form a tool
There is the carbon fibre composite horizontal rotor fan housing of multidimensional structure.
Further technical solution is:
Carbon fibre tow in the step 1 is T300 grade carbon fiber tow (tensile strength is greater than 3800MPa) rank or more,
The resin can be one of epoxy resin, phenolic resin, bimaleimide resin.
Aluminium sheet in the step 1 is 3003 serial rustproof aluminium sheets, is easily formed by processing methods such as spinning or moldings
For fan housing shape core.
Winding method in the step 2 is completed using four-dimensional numerical control winding machine.
The warm temperature in heat curing process in the step 3 is no more than 250 DEG C.
Beneficial effect
The present invention preferably overcomes the shortcomings that prior art, and advantage is as follows:
1, this product technical solution twines the surrounding of the horizontal rotor fan housing shape core due to using carbon fibre tow
Around forming the enhancement layer of package, the allowable rotating speed of centrifuge horizontal rotor fan housing be greatly improved.
2, horizontal rotor fan housing shape core reinforcement is formd with the mode of winding, makes horizontal rotor fan housing that there is a kind of net
Shape envelope multidimensional structure improves horizontal rotor fan housing radial direction and the tangential intensity of circumference, solves conventional aluminum level of alloy and turns
Sub- fan housing the problem of deformation in operational process, improves the reliability of product because intensity is insufficient.
3, carbon fibre composite centrifuge horizontal rotor fan housing is enhanced using high-strength carbon fiber tow, traditional compared to using
The horizontal rotor fan housing of aluminum alloy material manufacture, alleviates the weight of horizontal rotor fan housing；An equal amount of horizontal rotor fan housing,
Since the shape core of carbon fibre composite horizontal rotor fan housing can be made thinner lighter, so carbon fibre composite is horizontal
Rotor fan housing structure is light and handy, reduces motor load, alleviates experimenter's manipulation strength.
4, carbon fiber it is wear-resisting, it is corrosion-resistant, do not generate the characteristics of metal fatigue so that carbon fibre composite horizontal rotor wind
Cover suitable application area is wider, the service life is longer.
Technical solution of the present invention is further illustrated with reference to the accompanying drawings and examples.
