Abstract

The utility model relates to a diagonal fan, which has large air volume, small volume, high efficiency and low noise, is widely used for ventilating and air exchange in working places. The diagonal fan is fixed and mounted by a support, composed of a support, a motor, an impeller, a guide vane, an inner cylinder and an outer cylinder, wherein the motor is concealed between the impeller and the inner cylinder, the outer cylinder is olive-shaped, comprises a conical frustum air inlet outer cylinder and air outlet cylinder, which abuts with each other, each of the air inlet and the air outlet of the outer cylinder is provided with an A surface, a flange flaring outwards from the A surface forms a alpha angle with the A surface, wherein the alpha angle ranges from 10 degrees to 50 degrees. The utility model has the characteristics of light weight, high efficiency, convenient installation and low noise. The performance is between those of the centrifugal fan and the axial-flow fan, compared with the centrifugal fan, the compression is lower than that of the centrifugal fan, but the flow is larger than that of the centrifugal fan; compared with the axial-flow fan, the compression is higher than that of the axial-flow fan, but the flow is smaller than that of the axial-flow fan. The efficiency of the diagonal fan is higher than that of the axial-flow fan, thus more energy-saving.

Description

Diagonal flow fan
Technical field
The utility model relates to diagonal flow fan, and this fan delivery is big, profile is little, efficient is high, noise is low, is widely used in ventilation, the ventilation of operational site.
Background technique
Raising along with living standards of the people; people to the life, work environmental protection consciousness also in continuous raising; in the live and work place; waste gas and harmful gas; because Temperature Influence is many on the top in house, this product be applicable to be suspended on the roof below, the air near the roof is transported to outside the room; keep the fresh of air within doors, be usually used in ventilation, the ventilation in places such as factory, office.
The characteristics of diagonal flow fan: flow is greater than centrifugal fan, and total head is higher than axial fan, and volume is less than centrifugal fan.Diagonal flow fan is widely used in pipeline pressurization, the ventilation place of air-supply and air draft and tall building, public building.
The diagonal flow fan that uses on the market adopts the cylinder type urceolus mostly now, and the water conservancy diversion tube length is also made complexity, and the material consumption is big, cost is high.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of product with compact structure, boundary dimension is little, fixedly mounts diagonal flow fan easily.
For solving the problems of the technologies described above, the utility model provides following technical proposals: diagonal flow fan installs and fixes by support, and it is made of motor, impeller, stator, inner core and urceolus, wherein, motor is hidden in the middle of impeller and the inner core, has shortened blower fan in axial length; Described urceolus is Olive Shape, comprises the truncated cone air inlet urceolus of butt joint and the urceolus of giving vent to anger, and respectively is provided with an A face at suction port, the place, air outlet of urceolus, flange and A face from A towards outer enlarging are the α angle, the convenient soft connector of installing, wherein, the α angle is 10 °~50 °.Because the axial dimension of blower fan is short, no inlet/outlet flange, the flange of inlet/outlet has partly substituted slip ring, so overall weight is light, structure is small and exquisite.
Be convenient processing, the profile of the described air inlet urceolus and the urceolus of giving vent to anger and measure-alike just can be processed with equal dies, improves the utilization ratio and the production and processing efficient of mould.
Described A face is a cylindrical surface, and suction port, air outlet are the round mouth with the footpath, as long as just can connect with soft connector with the larynx hoop, is more suitable for connecting circular pipeline.
Symmetry is fixed four plate racks on urceolus, and mounting bracket is simple in structure, in light weight, can use round steel to hang on the roof.
The supporting surface of described motor is placed on the centre of electrical axis, installs to stablize by four bolts to be connected with the blower fan inner core.
The utility model is in light weight, efficient is high, easy for installation, being on the performance between centrifugal blower and the axial-flow blower, compare with centrifugal blower, the pressure of diagonal flow fan is lower than centrifugal blower, but flow is then greater than centrifugal blower; Compare with axial-flow blower, the pressure of diagonal flow fan is higher than axial-flow blower, but flow is then less than axial-flow blower, and the efficient of diagonal flow fan is than axial-flow blower height, and is more energy-conservation.
Diagonal flow fan is used the meridian accelerator theory, adopts diagonal impeller and drum abdomen shape awl tube shell, and the air-flow on the blower fan meridional plane is quickened, static pressure gradient reduces, thereby avoid or reduced the air-flow lift-off, improved pressure coefficient and fan efficiency, reduced noise.

Embodiment
With reference to the accompanying drawings
Shown in accompanying drawing 1 scheme of installation, diagonal flow fan is hung on the roof by support 1 usefulness round steel.Shown in accompanying drawing 2 the utility model blower fan plan views and the accompanying drawing 3 the utility model blower fans left side sectional view, it is made of support 11,12,13,14, motor 5, impeller 6, stator 4, inner core 3 and urceolus, inner core 3 is fixing with the urceolus 2 of giving vent to anger by stator 4, and motor 5 is fixed between inner core 3 and the impeller 6; Impeller 6 adopts diagonal impeller, is installed in 5 in motor and goes up rotation and carry air; Described motor bearing face 8 is located at the centre of electrical axis, can fixedly connected with inner core by four bolts.
Described urceolus is Olive Shape, comprises the truncated cone air inlet urceolus 7 of butt joint and the urceolus 2 of giving vent to anger, and respectively is provided with an A face at suction port, the place, air outlet of urceolus, flange and A face from A towards outer enlarging are the α angle, the convenient soft connector of installing, wherein, the α angle is 10 °~50 °.Because the axial dimension of blower fan has shortened, no inlet/outlet flange, the flange of inlet/outlet has partly substituted slip ring, so overall weight is light, structure is small and exquisite.
In the present embodiment, the profile of the air inlet urceolus and the urceolus of giving vent to anger and measure-alike just can be processed with equal dies.
Described A face is a cylindrical surface, and suction port, air outlet are the round mouth with the footpath, as long as just can connect with soft connector with the larynx hoop, is more suitable for connecting circular pipeline.
