Abstract
The utility model relates to an axial-flow fan with large air amount and high wind speed. A fan base is composed of an inner ring, a middle ring, a fan base blade, a shell body and a reinforcing rib which are all cast into a whole. The inner ring and the middle ring are connected through the reinforcing rib, the middle ring and the shell are connected through the fan base blade, the fan base forms a three-layer cavity by the shell, the inner ring and the middle ring, a stator is assembled on the inner ring of the fan base, a rotor spindle is arranged on a bearing, an impeller is composed of an impeller body and impeller blades connected with the impeller body, the impeller is arranged on a rotor shaft, the impeller blades are designed into rotor wing shapes, and the energy of the gas ascends due to thrust of the blade on the impeller, so that the wind is large in air amount and high in wind speed. The fan base blade is designed into a shaft bushing shape and arranged at the position of an air outlet at the bottom part of the fan base, and axial flowing air is supercharged again, so that the wind forms a spiral shape, so as to achieve high air pressure, large air quantity and fast wind speed. The axial-flow fan with the large air amount and the high wind speed has the advantages of large air quantity, high wind speed, small size, light weight, small noise, convenience in installation and dismantle, and simple structure.
Description
Technical field: the utility model relates to a kind of Wind Volume high wind speed axial-flow blower.
Background technique: present axial-flow blower is by motor, impeller, casing forms, blade generally all can rotation angle, most of axial-flow blower all is furnished with a cover blade hydraulic regulating device, complex structure, and maintenance is inconvenient, this axial-flow blower only has impeller blade that wind regime is provided, blast is low, and air quantity is little, wind speed is slow, the occasion of can not meet the demands Wind Volume, high wind speed.For example, the cooling blower used of railway traffic linear motor.
Summary of the invention: the purpose of this utility model provides that a kind of air quantity is large, wind speed is fast, noise is little, easy installation and removal, Wind Volume high wind speed axial-flow blower simple in structure.The technical solution of the utility model is: support is by interior ring, middle ring, the support blade, housing, stiffening rib forms, and be cast as one, connected by stiffening rib between interior ring and the middle ring, be connected by the support blade between middle ring and the housing, support is by housing, interior ring, middle ring forms three layers of cavity, on stator is assembled to and encircles in the support, rotor main shaft is installed on the bearing, impeller is made of impeller body and the impeller blade that is connected with impeller body, and is cast as one, and impeller is installed on the rotor shaft, fix with bolt, impeller blade is designed to the rotor shape, and the support blade design becomes the bearing shell shape, is positioned at the position of support bottom exhaust outlet.
Working principle of the present utility model:
When vane rotary, gas axially enters impeller from intake grill, gas is subject to pushing of impeller upper blade and the energy of gas is raise, then flow in housing and the middle ring cavity, blade becomes axial flow with the deflection air-flow, flow into the support blade, and the support blade is with the again supercharging of wind of axial flow, it is spiral-shaped that wind is formed, and directly keeping watch by the support blade is blown in the air compartment again.
Technique effect of the present utility model:
1, impeller blade is designed to the rotor shape, and gas is subject to pushing of impeller upper blade and the energy of gas is raise, and makes wind form Wind Volume, high wind speed.
2, the support blade design becomes the bearing shell shape, is positioned at the position of support bottom exhaust outlet, and with the again supercharging of wind of axial flow, it is spiral-shaped that wind is formed, and further forms the blast height, air quantity is large, wind speed is fast.
3, support forms three layers of cavity by housing, interior ring, middle ring, makes the blower fan volume little, lightweight.
4, support is designed to be comprised of interior ring, middle ring, support blade, housing, stiffening rib, and is cast as one; Impeller Design becomes to be comprised of impeller body, impeller blade, and is cast as one, makes fan noise little, and installation, convenient disassembly are simple in structure.
Description of drawings:
Fig. 1 is the whole sectional view of the utility model.
Fig. 2 is the plan view of the utility model impeller.
Embodiment:
As shown in Figure 1, a kind of Wind Volume high wind speed axial-flow blower, support 1 is comprised of interior ring 2, middle ring 3, support blade 5, housing 6, stiffening rib 10, and be cast as one, connected by stiffening rib 10 between interior ring 2 and the middle ring 3, be connected by support blade 5 between middle ring 3 and the housing 6, support 1 forms three layers of cavity by housing 6, interior ring 2, middle ring 3, make the blower fan volume little, lightweight.Stator 4 is assembled to and encircles on 2 in the support, rotor 7 main shafts are installed on the bearing 8, as shown in Figure 2, impeller 12 is made of impeller body 13 and the impeller blade 11 that is connected with impeller body 13, and is cast as one, impeller 12 is installed on rotor 7 axles, fix with bolt, impeller blade 11 is designed to the rotor shape, and gas is subject to pushing of impeller upper blade and the energy of gas is raise, make wind form Wind Volume, high wind speed.Support blade 5 is designed to the bearing shell shape, is positioned at the position of support bottom exhaust outlet 9, and with the again supercharging of wind of axial flow, it is spiral-shaped that wind is formed, and further forms the blast height, air quantity is large, wind speed is fast.
The utlity model has Wind Volume, high wind speed, volume is little, lightweight, noise is little, easy installation and removal, the characteristics such as simple in structure.
