Abstract
The utility model relates to a guide vane type motor installation frame of a pipeline axial flow fan. The guide vane type motor installation frame is fixed to a cylinder and comprises a motor installation portion, at least four guide vanes and a shaft hole. The guide vanes are distributed between the cylinder and the motor installation portion. One end of each guide vane is welded to the inner side of the cylinder, and the other end of each guide vane is welded to the outer side of the cylinder. The guide vane type motor installation frame has the advantages that the pipeline axial flow fan can be completely fixed from the front face, the rear face, the upper face, the lower face, the left face and the right face, the displacement problem produced when an impeller rotates at a high speed is effectively solved, the impeller is prevented from rubbing the inner wall of a pipeline of the cylinder, the service life of the impeller is prolonged, maintenance expenses are reduced, and noise and potential safety hazards are eliminated.
Description
Technical field
The utility model relates to a kind of guide-vane motor mounting rack of pipeline axial flow fan, is mainly used in the pipeline axial flow fan that is arranged on vertical wall.
Background technique
Pipeline axial flow fan is generally arranged in factory's ventilation duct, is rotated, for from indoor discharge or the outdoor gas of sending into, the ventilation requirement of complete design defined by motor drives impeller.Because this type of blower fan is generally arranged in cylinder pipe, mostly adopt seat assembling structure fixed electrical machinery, although be enough to ensure upper and lower balance, all around equinoctial point is not easy to fix, and makes to occur offset phenomena after fan operation overlong time.In this case, impeller and cylinder pipe left and right distance further, and impeller and cylinder pipe friction make a noise, thereby affect the initial performance of blower fan itself, accelerate the aging of the moving elements such as motor, increased the workload of maintaining, caused loss to user.In addition because left and right equinoctial point is not easy fixing problem, may cause impeller to cause impeller fracture with cylinder pipe collision in running, bring potential safety hazard to user.
Summary of the invention
Technical problem to be solved in the utility model is: the guide-vane motor mounting rack of pipeline axial flow fan is provided, to reach simple and reliable for structure, effectively prevents the offset phenomena of pipeline axial flow fan in the time running up.
The utility model solves the problems of the technologies described above taked technological scheme: a kind of guide-vane motor mounting rack of pipeline axial flow fan, be fixed on cylinder, motor mounting rack comprises motor mounting part, at least 4 stators and axis hole, described stator is distributed between cylinder and motor mounting part, one end is welded on cylinder inner side, and the other end is welded on motor mounting part outside.
On the basis of such scheme, described axis hole is positioned at motor mounting part center, coaxial with cylinder.
On the basis of such scheme, described cylinder can be both independent component, can be also a certain section in cylinder pipe.
On the basis of such scheme, described stator is oblique half U type.
The utility model has the advantage of: can before and after, upper and lower, left and right six faces are completely fixed pipeline axial flow fan, effectively solve the displacement problem of impeller in the time running up, prevent wall friction in impeller and cylinder pipe, prolongation impeller working life, reduce and safeguard as use, abate the noise and potential safety hazard.

Embodiment
Referring to Fig. 1 is plan view of the present utility model, and Fig. 2 is the structural representation of the utility model while being unkitted impeller and Fig. 3 structural representation while being the utility model assembling impeller:
As shown in Figure 1, a kind of guide-vane motor mounting rack of pipeline axial flow fan, be fixed on cylinder 1, this motor mounting rack 2 comprises 21, at least 4 stators 22 of motor mounting part and axis hole 23, described stator 22 is distributed between cylinder pipe 1 and motor mounting part 21, one end is welded on cylinder 1 inner side, and the other end is welded on motor mounting part 21 outsides, by stator 22, motor mounting part 21 is supported and is fixed in cylinder.
As shown in Figure 2, described cylinder 1 can be both independent component, can be also a certain section in continuous cylinder pipe, and the present embodiment cylinder 1 is independent component, and motor mounting rack 2 is fixed in cylinder 1 by stator 22.
As Figure 2-3, described stator 23 is oblique half U type.
On the basis of such scheme, described axis hole 23 is positioned at motor mounting part 2 centers, coaxial with cylinder pipe 1.
As shown in Figure 3, when assembling, motor 4 is fixed on the rear side at motor mounting part 21 by bolt 5, and the main shaft 41 of motor 4 connects impeller 3, the impeller 3 of drive motor scaffold 2 front sides through axis hole 23.The present embodiment has multi-disc to be the stator of oblique half U type, before and after can playing, six of upper and lower, left and right be completely fixed pipeline axial flow fan, effectively solve the displacement problem of impeller 3 in the time running up, prevent impeller 3 and the interior wall friction of cylinder pipe 1.
