Abstract
The utility model relates to a novel high-strength high-pressure centrifugal fan casing, which belongs to the technical field of fan casing manufacture. A machine casing is composed of two lateral plates of the machine casing and a girth sheet of the machine casing, wherein an air inlet pipe and an air inlet flange are arranged in the lateral plate of the machine casing on one side of the machine casing, and a driven coupling flange is arranged in the lateral plate on the other side of the machine casing. The two lateral plates of the machine casing are provided with stiffening rings, reinforcing ribs are arranged between the stiffening rings and a connecting pipe of the air inlet flange and between the stiffening rings and a connecting pipe of the driving coupling flange. The utility model has the advantages that the resonance of the blower can be avoided in operation because of a plurality of storage structures formed on large plane surfaces on the lateral sides, and the utility model has an auxiliary function of reducing noises and lightening the whole machine vibration; air inlet and outlet flanges are selected and matched to the flanges of the standard pipe to make the machine body more firm and more beautiful in appearance, and the utility model can be used for a user to connect wind pipes conveniently.
Description
Technical field:
The utility model relates to a kind of light high-intensity centrifugal high pressure fan casing, belongs to fan casing and makes the field.
Background technique:
Existing centrifugal high pressure fan casing, on structural design, the forward and backward side plate of casing adopts bigger thickness that high rigidity is provided, though certain effect is arranged, but flat, the resonance phenomenon of drum when flat structure still exists operation, many, the weight of equipment increase of consumptive material simultaneously.
Summary of the invention:
Purpose of design: avoid the deficiency in the background technique, design a kind of when no matter being carrying malleation or negative pressure, all have the bearing strength height, indeformable, in light weight, consumptive material is little, do not have resonance and sense organ strong attractive in appearance.
Design proposal: the major function of fan casing is a rule bundles air-flow, make before its direction on demand into and out of.Next is to need its different azimuth of casing of enough intensity, particularly high pressure positive blower must bear bigger malleation or negative pressure.The design's casing is light-duty, high-strength structure, whole casing adopts relatively thin sheet material (be about existing like product about 1/2), but between the outer surface of forward and backward side plate is provided with stiffening ring, circle and circle, radiate and adorn straight plate stiffening rib and be connected, no matter cause whole casing is to bear malleation or negative pressure does not all produce distortion, consumptive material is economized, and the more important thing is and has avoided resonance effectively.Its technological scheme: high strength centrifugal high pressure fan casing, be provided with in the housing side wall of two housing side walls (10) and casing girth sheets (11) formation casing and casing one side in air intake pipe (5) and air intake flange (6), the opposite side housing side wall and be provided with transmission joint dish (9), two housing side walls are provided with stiffening ring (3), are provided with stiffening rib (4), stiffening ring (3) between the connecting tube of stiffening ring (3) and air intake flange (6) and are in transmission connection to be provided with stiffening rib (4) between dish (9) connecting tube.
The utility model is compared with background technique, and the one, because the big plane of side table forms from many storehouse type structures, the resonance when having avoided the blower fan running is to reducing noise, alleviating complete machine oscillation auxiliary effect is also arranged; The 2nd, the apolegamy of the flange of inlets and putlets of ventilation is the standard pipe flange, make body firmer, attractive in appearance and be convenient to the user and connect airduct; The 3rd, avoided resonance phenomenon effectively.

Fig. 2 is the side-looking structural representation of Fig. 1.
Fig. 3 is the backsight structural representation of Fig. 1.
Fig. 4 is the plan structure schematic representation of Fig. 1.
Embodiment:
Embodiment 1: with reference to accompanying drawing 1～4.High strength centrifugal high pressure fan casing, be provided with in the housing side wall (front side plate) of two housing side walls 10 and casing girth sheets 11 formation casings and casing one side in air intake pipe 5 and air intake flange 6, the opposite side housing side wall (back side panel) and be provided with transmission joint dish 9, forward and backward side plate all adopts steel plate or corrosion resistant plate manufacturing, two housing side walls (forward and backward side plate) are provided with stiffening ring 3, are provided with stiffening rib 4, stiffening ring 3 between the connecting tube of stiffening ring 3 and air intake flange 6 and are in transmission connection to be provided with stiffening rib 4 between dish 9 connecting tubes.Air outlet tube 2 is communicated with casing and the air outlet tube port is provided with outlet air flange 1.Be provided with cover plate 7 in the side plate of casing one side, cover plate 7 is provided with between the connecting tube of strengthening Fig. 3 and stiffening ring 3 and air intake flange 6 and is provided with stiffening rib 4.Be provided with stiffening rib between stiffening ring and stiffening ring.Casing adopts the welding procedure welding fabrication.Casing sealing: seal approach is not generally adopted in relative rotation place with the casing axis hole of existing high pressure positive blower transmission shaft, can cause the partial discharge loss during use.Though not obvious because of its flow than influencing greatly, be the waste of parameter and energy after all.The application is in order to solve this defective, on structural design, sealing for transmission shaft and casing axis hole, employing changes the motor of being furnished with front cover, the flange plate that cooperates with end cap is set on casing, make whole motor shaft in the inner rotation of the casing of sealing, simultaneously, the inlets and putlets of ventilation of blower fan all uses circular standard flange, changed the import and export leakage phenomenon that flange brought that existing centrifugal high pressure fan adopts the shaped steel welding to form, make that complete machine is on-stream to have reached dead-tight effect, performance is more reliable, moves more energy-conservation.
What need understand is: though the foregoing description is to the utility model detailed explanation of contrasting; but these explanations are just illustrative to the utility model; rather than to restriction of the present utility model; any innovation and creation that do not exceed in the utility model connotation all fall in the protection domain of the present utility model.
