Abstract
The utility model relates to an axial-flow fan, which aims to provide an explosion-proof axial-flow fan having a larger usage range. The explosion-proof wall type axial-flow fan comprises a fan housing, a motor rack, motor rack legs, impellers and a motor. The impellers are disposed in a flow channel cylinder. Most part of the motor exposes outside of the fan housing. A junction box is fixed to the upper part of the motor. As for a conventional axial-flow fan, a motor is completely disposed in a housing cylinder. The junction box of the explosion-proof motor is much different than a common motor in height, due to which a motor cannot be normally disposed in the cylinder. As for the explosion-proof axial-flow fan, the impellers are disposed in the flow channel cylinder, and the most part of the motor exposes outside, and thereby the height of a junction box will not affect the assembling of a fan.
Description
Technical field
The utility model relates to a kind of axial-flow blower, particularly relates to a kind of explosion-proof wall type axial-flow blower.
Background technique
Because anti-explosion motor is bigger than the common electric machine shell sizes, can't be installed in the axial-flow blower cylindrical shell so anti-explosion motor often occurs, has limited the type selecting condition.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of using scope wider, has remedied the explosion-proof wall type axial-flow blower of the explosion-proof model scope of plain shaft flow fan.
The explosion-proof wall type axial-flow blower of the utility model; Comprise flow blower casing, electric machine support, electric machine support pin, impeller and motor; Said impeller is placed in the runner cylindrical shell, and said motor major part is exposed at the outside of flow blower casing, and terminal box is fixed on the top of motor.
Compared with prior art the beneficial effect of the utility model is: the main structure of the utility model comprises flow blower casing, electric machine support, electric machine support pin, impeller, motor etc.Compare, former common axial fan is to place in the casing cylindrical shell motor is whole, and the terminal box of anti-explosion motor differs greatly than the common electric machine height, often cause for this reason motor can't normally be placed in can cylindrical shell in.And explosion-proof axial flow fan just is placed on impeller in the runner cylindrical shell, and the motor major part is exposed, and the height of terminal box can not have influence on the assembly problem of blower fan in other words.Corresponding Fan Selection will be chosen less model.
This blower fan need not consider that basically these are present, and selecting for use of blower fan is wider, and cost is compared the plain shaft flow fan and can be reduced.
Description of drawings
Fig. 1 is the plan view of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the embodiment of the utility model is described in further detail.Following examples are used to explain the utility model, but are not used for limiting the scope of the utility model.
As shown in Figure 1; A kind of explosion-proof wall type axial-flow blower comprises flow blower casing 1, electric machine support 4, electric machine support pin 5, impeller 2 and motor 6, and impeller 2 is placed in the runner cylindrical shell; Motor 6 major parts are exposed at the outside of flow blower casing 1, and terminal box 3 is fixed on the top of motor 6.
The main structure of the utility model comprises flow blower casing, electric machine support, electric machine support pin, impeller, motor etc.Compare, former common axial fan is to place in the casing cylindrical shell motor is whole, and the terminal box of anti-explosion motor differs greatly than the common electric machine height, often cause for this reason motor can't normally be placed in can cylindrical shell in.And explosion-proof axial flow fan just is placed on impeller in the runner cylindrical shell, and the motor major part is exposed, and the height of terminal box can not have influence on the assembly problem of blower fan in other words.Corresponding Fan Selection will be chosen less model.This blower fan need not consider that basically these are present, and selecting for use of blower fan is wider, and cost is compared the plain shaft flow fan and can be reduced.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and modification, these improvement and modification also should be regarded as the protection domain of the utility model.
Claims (1)
1. explosion-proof wall type axial-flow blower; Comprise flow blower casing, electric machine support, electric machine support pin, impeller and motor; It is characterized in that: said impeller is placed in the runner cylindrical shell, and said motor major part is exposed at the outside of flow blower casing, and terminal box is fixed on the top of motor.
