Abstract
The utility model discloses a large axial flow fan, which comprises an air duct, a motor and impellers, wherein the motor and the impellers are fixed in the air duct. The air duct comprises an upper half air duct and a lower half air duct which are detachably connected together. The upper half air duct and the lower half air duct can be connected together through bolts. Due to the fact that the air duct is combination of the upper half air duct and the lower half air duct, when the motor or the impellers need dismantling so as to maintain the fan, users only need to first remove connection of the upper half air duct and the lower half air duct, then remove the upper half air duct which is light in weight relatively, and can conveniently maintain the impellers or the motor or dismantle the impellers and the motor.
Description
Technical field
The utility model relates to a kind of axial-flow blower, particularly relates to a kind of large axial flow fan of dismounting for ease of maintenaince.Belong to field of fluid machinery.
Background technique
Along with the development of city and traffic, the construction in subway, tunnel is more and more, in long tunnel, needs to adopt blower fan to force supply and exhaust.What usually use in subway, the tunnel is a kind of large-scale axial-flow blower, like underground fan and tunnel blower fan, that its weight has even reach hundreds of kilograms.We know that the basic structure of axial-flow blower is a round air duct and be fixed on the motor in the air duct and be fixed on the impeller on the motor shaft, if when blower fan breaks down, need usually to remove impeller or in air duct, remove motor from motor.And these dismounting work all need in the air duct of sealing, to carry out, very inconvenience.
The model utility content
For overcoming above-mentioned defective, the utility model aim to provide a kind of when carrying out the blower fan maintenance easy-disassembling-assembling large axial flow fan.
For achieving the above object; The technological scheme that the utility model adopts is: a kind of large axial flow fan; Comprise an air duct and the motor, the impeller that are fixed in the air duct, said air duct is divided into first air duct and second air duct, and said first air duct is detachably connected with second air duct.
Said first air duct links together through bolt with second air duct.
Adopted the large axial flow fan of the utility model; Owing to be divided into its air duct the combination of first air duct and second air duct; When impeller in blower fan being keeped in repair need dismounting air duct or motor; Only need earlier to remove weight first lighter air duct relatively to the dismounting that is connected of first air duct and second air duct then, can be easily to impeller or motor keeps in repair or remove impeller and motor.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the perspective view of the utility model.
Among the figure: 1-air duct, 2-motor, first air duct of 3-, second air duct of 4-, 5-impeller, 6-bolt.
Embodiment
As shown in Figure 1; The utility model discloses a kind of large axial flow fan; Comprise an air duct 1 and the motor 2, the impeller 5 that are fixed in the air duct 1, its innovative point is that mainly said air duct 1 is divided into first air duct 3 and second air duct 4, and said first air duct 3 is detachably connected with second air duct 4.When blower fan assembles, be fixed on the base of motor 2 in second air duct 4, be fixed on impeller 5 on the output shaft of motor 2 again after, be fixed to first air duct 3 on second air duct 4 at last, make first air duct 3 and second air duct 4 synthetic air ducts 1.
In practical application, said first air duct 3 can link together through bolt 6 with second air duct 4.Can certainly adopt other Placement, not remake here one by one and introduce.
Claims (2)
1. large axial flow fan; Comprise an air duct (1) and be fixed on motor (2), the impeller (5) in the air duct (1); It is characterized in that said air duct (1) is divided into first air duct (3) and second air duct (4), said first air duct (3) and second air duct (4) are detachably connected.
2. large axial flow fan according to claim 1 is characterized in that said first air duct (3) and second air duct (4) link together through bolt (6).
