Impeller and its manufacturing technology ", then its structure point front shroud, blade, back shroud combine, and this impeller is also fluid
The centrifugation pump mode for axially entering, radially going out.201010552348.3 " a kind of carbon fibre resin base composite woods that the army of manifesting proposes
Expect the noncorrosive pump of manufacture ", the impeller for using is chopped strand silk and the impeller of resin compounded, and the uniformity of its fiber distribution takes
Whether certainly uniform in the fiber distribution before solidification, the laying method from fiber filament laminate is different.Jiangsu concerted effort is electrically limited
A kind of 201410393886.0 " impellers " of the propositions such as company Wu Yuying, using polyacrylonitrile carbon fiber composite material impeller, will
Saw tooth profile is made at impeller direction of rotation edge, and to shred the impurity in fluid, its essence is still that fluid axially enters radially
The receded disk impeller for going out.The 201310164115.X of the propositions such as Yibin Hai Site fibers Co., Ltd Duan Meike " use by one kind
In the epoxy furans carbon fibre material and its impeller of pump of manufacture of manufacture impeller of pump ", propose to use epoxy furans carbon fibre material
Manufacture impeller technology, can at a temperature of 90 degree good trandfer fluid, the carbon fiber of this impeller is also with chopped strand
Formal distribution is in the middle of impeller.The positive outstanding CN200910096658.6 for proposing of Jiaxing UniTech Composites Co., Ltd. Cai is " a kind of
The blade body that wind power generation blade and its manufacturing technology " is used is by rigid foam sandwich and is coated on outside rigid foam sandwich
Glass fabric is constituted with basalt fibre fabrics composite bed.Zhuzhou Times new materials Science Co., Ltd Feng Xue is refined etc.
The CN200910227056.X " large-scale composite material wind-power blade and preparation method thereof " of proposition, the composite material wind-power blade
Constituted including suction surface housing, pressure face housing and the shear web being fixed between two housings.Above technology is all to use carbon
Fiber as reinforcing material, various types of resins as matrix composite material impeller, but function is different, the blade of use
Form and manufacturing process are also different, do not have in a kind of impeller manufacture that can be applied to axial flow blower.
