Description
Technical field
The utility model relates to a kind of centrifugal blower fan blade wheel, specifically a kind of stem pressing glass reinforced plastics centrifugal blower fan blade wheel.
Background technique
Centrifugal blower is the mechanical energy relying on input, and improve gas pressure and to supply gas side by side the machinery of body, it is a kind of driven fluid machinery.Centrifugal blower is widely used in factory, mine, tunnel, cooling tower, vehicle, the ventilation of boats and ships and building, dust discharge and cooling; The ventilation of boiler and industrial furnace and air inducing; Cooling in the apparatus of air conditioning and domestic electric appliance and ventilation; The oven dry of cereal and selecting and recommending; The inflation of wind-tunnel wind regime and Hovercraft and propelling etc.
Centrifugal blower essence is a kind of variable-flow constant-voltage equipment.When rotating speed one timing, the pressure-flow theoretical curve of centrifugal blower should be straight line. due to internal losses, actual characteristic curve is bending.The pressure produced in centrifugal blower is subject to the considerable influence of intake temperature or variable density.To a given air inflow, the pressure produced time the highest intake temperature (air density is minimum) is minimum.For a given pressure versus flow characteristic curve, just there are a power and rating curve.When blower is with constant-speed operation, for a given flow, required power raises with the reduction of intake temperature.
Impeller in centrifugal blower is a key working part in centrifugal blower, and the service behaviour for centrifugal blower can have a huge impact.Under mostly centrifugal blower be to be operated in the environmental conditions of pH value corrosion, can produce very large adverse effect to the working life of metallic impeller, therefore, corrosion resistant glass ring draught fan impeller just arises at the historic moment thereupon.Existing glass fibre reinforced plastic centrifugal mainly passes through manual manufacture, not only manufacturing efficiency is low, labor intensity is large, the recruitment personnel of manufacturing enterprise are many, cost of production is high, and, because the connection of the impeller blade in draught fan impeller and upper dish and/or lower wall is mainly with bolts, there is the shortcoming connected loosely in this Placement, also has a great impact the bulk strength of draught fan impeller.
Model utility content
The purpose of this utility model is just to provide a kind of stem pressing glass reinforced plastics centrifugal blower fan blade wheel, with the problem that the impeller blade connectivity robustness difference and draught fan impeller bulk strength that solve existing glass fibre reinforced plastic centrifugal are not high.
The utility model is achieved in that a kind of stem pressing glass reinforced plastics centrifugal blower fan blade wheel, include the upper dish of ring and discoidal chassis, and the some impeller blades be connected between described upper dish and described chassis, it is characterized in that, described impeller blade distributes with the gradually evolution formula even circumferential along described chassis, described impeller blade is connected with described chassis Integral mold is molded, the upper end of described impeller blade be shaped with for connect described on dish upright cornice; The end face of dish circumferentially has the through inserting groove of involute on described, described cornice on described impeller blade is plugged in described inserting groove, in described cornice, be embedded with the bayonet socket screw mandrel of diameter slightly larger than described cornice gap width, the covering suitable for reading of the described inserting groove of dish has glass fibre reinforced plastics packing layer on described.
The inside of described impeller blade is hollow cavity, and the bottom opening of described hollow cavity is opened in the bottom surface on described chassis, is provided with the interlayer of isolation impeller blade hollow cavity in the bottom of described cornice.
The upper edge of the described cornice on described impeller blade is concave arc shape edge, and the radian at this concave arc shape edge is identical or substantially identical with the notch radian of the described inserting groove of described upper dish end face.
The utility model by making cornice on impeller blade, be plugged in the scarfing slot coiled, snapping in again by bayonet socket screw mandrel, cornice appropriateness is strutted, thus be fixedly connected on and coil, thus achieve impeller blade to be connected with upper dish and the stable of chassis, can ensure the bulk strength of fan impeller, the impeller blade solved in traditional fiberglass blower fan impeller can not stablize with upper dish and chassis the problem be connected.And the utility model can realize Mechanized Processing and the mass production of fiberglass blower fan impeller, compared to the manual manufacture mode of traditional glass fibre reinforced plastic centrifugal, can significantly enhance productivity, save recruitment personnel, reduce cost of production, improve the competitiveness of product in market.

Embodiment
As shown in Figure 1, the utility model stem pressing glass reinforced plastics centrifugal blower fan blade wheel comprises the parts such as dish 1, chassis 3 and impeller blade 2.The body of upper dish 1 is ring, card is the concave arc surface that middle part is slightly high, the end is omited in outer, the card of upper dish 1 circumferentially has ten (variable amounts) inserting groove 4(Fig. 4), all inserting grooves 4 with gradually evolution formula along the circumference uniform distribution of card, the both sides, bottom surface of each inserting groove 4 have stretch out downwards protect edge, to improve the area of contact with impeller blade, improve join strength.
Chassis 3 is circular disk body, has outstanding center round platform 8 in the middle part of card, when making chassis, presets the lining 10 of a steel at the center on chassis 3, and the center hole of lining forms axis hole 9, has keyway, so that the connection of draught fan impeller and motor shaft in axis hole 9.
Impeller blade 2 and chassis 3 use glass fibre reinforced plastic material Integral mold molded.Impeller blade 2 distributes (Fig. 2) with the gradually evolution formula even circumferential along chassis 3, is shaped with upright cornice 5(Fig. 5 in the upper end of impeller blade 2).Cornice 5 is arranged on the upper end of impeller blade 2, is two relative sheet body structures, middlely forms core groove 6(Fig. 1).Cornice 5 on impeller blade 2 is plugged in the inserting groove 4 of dish 1.
In Fig. 1, be embedded with bayonet socket screw mandrel 7 in the core groove 6 formed by cornice 5 on impeller blade 2, bayonet socket screw mandrel 7 makes with the iron wire of diameter slightly larger than cornice gap width.After bayonet socket screw mandrel 7 snaps in cornice, the upper edge of cornice 5 is strutted to both sides appropriateness, thus dish 1 is firmly connected with impeller blade 2.Afterwards, at covering one deck glass fibre reinforced plastics packing layer suitable for reading of the inserting groove 4 of upper dish 1, for hiding the gap of bayonet socket screw mandrel 7 and cornice 5.Finally, polishing finishing is carried out to the glass fibre reinforced plastics packing layer after solidification.
The inside of impeller blade 2 is hollow cavity, and the bottom opening of this hollow cavity is opened in the bottom surface (Fig. 3) on chassis 3.The interlayer of isolation impeller blade hollow cavity is provided with in the bottom of cornice 5.The mold core plate that grafting is set in the bottom surface on chassis 3 when namely making, to form the internal cavities body of impeller blade.For ease of depanning, the thickness direction of mold core plate and width direction are all with certain tapering.Therefore, the profile of impeller blade 2 at thickness direction and width direction also just with certain tapering.In Fig. 5, the upper edge of the cornice 5 on impeller blade 2 is concave arc shape edge, and the radian at this concave arc shape edge is identical or substantially identical with the notch radian of the inserting groove 4 of upper dish 1 end face, forms good position matching to make the two.
