Abstract
The utility model relates to an axial-flow type fan and aims at providing a volute-free impeller axial-flow type fan with guide vanes with guide vanes, which can achieve higher pressure under the same flow and lower cost compared with a mixed-flow fan and comprises a cylinder body. A motor and the guide vanes are installed in the cylinder body, and the number of the guide vanes is four to eight. The volute-free impeller axial-flow type fan with the guide vanes adopts an eccentric impeller axial-flow type air exhaust, reduces rotating time of air, improves efficiency of the fan by means of adding the guide vanes to the cylinder body, achieves a higher pressure under the same flow, and has lower cost compared with the mixed-flow fan.
Description
Technical field
The utility model relates to a kind of axial-flow blower, particularly relates to a kind of no spiral case impeller axial fan with stator.
Background technique
Axial fan is booster again, is industrial and mining enterprise's a kind of blower fans commonly used, and it is different from general blower fan; All in a cylinder, profile is exactly a tubular, is used for local ventilation for its motor and fan blade; Easy for installation, the ventilation effect is obvious, safety.Flow-mixing blower fan is the blower fan between axial-flow blower and centrifugal blower; The impeller of flow-mixing blower fan is not only done centrifugal motion but also is axially moved by air; The motion of air has mixed axial flow and centrifugal two kinds of forms of motion in the shell, flow-mixing blower fan, and wind stress factor is higher than axial-flow blower; Flow coefficient is bigger than centrifugal blower, is used in all occasions of " neither big nor small " of blast and flow.It has filled up the blank between axial-flow blower and the centrifugal blower, possess simultaneously to adorn characteristics simply and easily, but the cost of flow-mixing blower fan is higher.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of flow-mixing blower fan of comparing being issued to higher pressure with flow, and the no spiral case impeller axial fan of the band stator that cost also can be lower.
The no spiral case impeller axial fan of the band stator of the utility model comprises cylindrical shell, and motor and water conservancy diversion leaf are installed in said cylindrical shell, and the quantity of said water conservancy diversion leaf is 4-8.
Compared with prior art the beneficial effect of the utility model is: the utility model adopts the air draft of centrifugal impeller shaft streaming; Through cylindrical shell being increased the method for water conservancy diversion leaf; Gas is reduced to spin the time; Improved fan efficiency, compare flow-mixing blower fan and be issued to higher pressure with flow, and cost also can be lower.
Description of drawings
Fig. 1 is the plan view of the utility model;
Fig. 2 is the left view of Fig. 1.
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 depicted in figs. 1 and 2, a kind of no spiral case impeller axial fan with stator comprises cylindrical shell 1, and motor 2 and water conservancy diversion leaf 3 are installed in cylindrical shell 1, and the quantity of water conservancy diversion leaf 3 is 4-8.
The utility model adopts the air draft of centrifugal impeller shaft streaming, through cylindrical shell 1 being increased the method for water conservancy diversion leaf, gas is reduced spin the time, has improved fan efficiency, compare flow-mixing blower fan and be issued to higher pressure with flow, and cost also can be lower.
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. the no spiral case impeller axial fan with stator comprises cylindrical shell, and motor and water conservancy diversion leaf are installed in said cylindrical shell, it is characterized in that: the quantity of said water conservancy diversion leaf is 4-8.
