Abstract
The invention discloses an impeller of a resin-based carbon fiber composite material acid-resistant pump. The impeller of the resin-based carbon fiber composite material acid-resistant pump comprises a cover plate and blades, wherein the cover plate is provided with grooves, and the blades are provided with bosses which are matched with the shapes and the positions of the grooves. According to the impeller of the resin-based carbon fiber composite material acid-resistant pump, since a front cover plate, a rear cover plate, a rear cover plate and blades of the impeller are manufactured in a split manner and a manufacturing method comprising steps of laying on a mold, molding, solidification, demolding and grinding for formation and final integral assembling is adopted, the problem of demolding is solved, the hydraulic model of the impeller is guaranteed and the performance of the pump is guaranteed not to change. The impeller of the resin-based carbon fiber composite material acid-resistant pump disclosed by the invention has the advantages that the weight is light and is one-fourth of the weight of a metallic acid-resistant pump, the anticorrosion service life is long, the strength is high and the efficiency is high. The pump is used in military, chemical, petrochemical, coking and nonferrous smelting industries, can replace expensive metallic pumps and low-efficiency plastic pumps, and has the effect of energy saving and emission reduction.
Description
Technical field
Of the present inventionly relate to pump housing technical field, particularly the impeller of resin-based carbon fiber composite acid-proof pump and manufacture method thereof.
Background technique
The impeller of pump is that the flow passage of pump divides core component, and the structure of impeller and manufacture method thereof are the keys ensureing pump performance.
It is the method once-through adopting casting that the impeller of metal acid-proof pump makes, and is finished product impeller after the processing of casting blank.
Prior art resin-based carbon fiber composite manufactures impeller, and after production technology adopts paving on mould, mold pressing, solidification, the demoulding, molding is shaping, and global formation can not the demoulding.
The anti-corrosive pump that carbon/carbon compound material manufactures, application number 200910012300.0, discloses and carbon fiber is cut into short silk, be combined with Bond again, mix releasing agent to load in mould and heat up shaping, product strength prepared by this technique is low, will affect the use of product.
Summary of the invention
In order to meet manufacturing technique requirent, guarantee that the demoulding is smooth, the application provides a kind of impeller of resin-based carbon fiber composite acid-proof pump, and front shroud of impeller (semi-open type does not have front shroud), back shroud and blade can make respectively.
Technological scheme of the present invention is:
The impeller of resin-based carbon fiber composite acid-proof pump, comprises cover plate and blade, and described cover plate is provided with groove, and described blade has the boss matched with described groove shapes and position.
The material that the impeller of resin-based carbon fiber composite pump of the present invention adopts is not particularly limited, and resin-based carbon fiber composite general in any field is all applicable.
Preferably, described groove is dove-tail form.
Preferably, described each blade be provided with 3 boss, corresponding cover plate is provided with 3 grooves.
Preferably, described blade and cover plate junction fixing, adopts carbon fiber wire adding additives to import shaping.Resin glue elected as by Bond of the present invention, as epoxy resin glue.
The present invention also provides the making method of the impeller of above-mentioned resin-based carbon fiber composite acid-proof pump, adopts paving, mold pressing, solidification, demoulding aftershaping.
Preferably, impeller cover and blade is adopted to make respectively, the technique of last overall package impeller.
In the manufacture process of front shroud and back shroud, cover plate is made groove by blade quantity, shape and bend angle, so that be loaded on wherein (see Fig. 7) along groove by shaping integrated plate blade.
The making of blade, in order to locate, when namely blade import and export position really fixes on and makes blade, in itself and forward and backward cover plate side contiguously, the place of three dovetail grooves opened in corresponding concave channels is opened and is produced three boss, sees Fig. 6, and the position of such blade on front and rear cover plate just secures.
In order to gain in strength, namely blade and cover plate junction is fixing, is embedded in three grooves prefabricated on cover plates by three boss that blade protrudes during design.It embeds in gap and imports shaping with carbon fiber wire adding additives, not only difficult drop-off between three, and intensity reaches requirement.
Resin-based carbon fiber composite manufactures the impeller of acid-proof pump, by front shroud of impeller, back shroud and blade split production, polish after adopting paving on mould, mold pressing, solidification, the demoulding shaping, the manufacture method of last overall package, be cut into carbon fiber that short silk is shaping to be compared with the pump leaf of epoxy furans carbon fibre material manufacture and metal acid-proof pump, solve a demoulding difficult problem, ensure that the hydraulic model of impeller, ensure that pump performance is constant.The impeller that resin-based carbon fiber composite of the present invention manufactures acid-proof pump has lightweight, and weight is metal acid-proof pump 1/4, and corrosion fatigue life is long, and intensity is large, and efficiency is high.This pump is used for military project, chemical industry, petrochemical industry, coking, nonferrous smelting industry etc., the metal pump of alternative costliness and inefficient plastic pump, energy-saving and emission-reduction.
