Abstract
The utility model relates to the axial flow fan, in particular to a low-temperature-resistant high-efficiency energy-saving cylindrical axial flow fan, which mainly consists of a diversion air cylinder, an impeller, a motor and a diversion end cover. The impeller consists of blades and a hub, the blades are fixedly provided with a connecting shaft, the hub is provided with a shaft hole, the connecting shafts are arranged in the shaft hole, the impeller is fixedly arranged on the motor through a washer and a clamping washer, the end of the impeller is fixedly provided with the diversion end cover, and the motor is fixedly arranged on the air cylinder through a motor bracket. Because the blades are arranged in the shaft holes between the upper hub and the lower hub, the angle can be adjusted and different angles can be selected according to the conditions of actual application, thereby meeting the requirements for different air volumes and pressures. The blade wings are in an aeronautical blade shape designed in accordance with the theory of aerodynamics in the field of the aviation flight, and the surfaces of the blades are provided with a coating, thereby significantly improving the efficiency, reducing the shaft power consumption, and saving 10 percent to 30 percent of power compared with similar products at home and abroad.
Description
Technical field:
The utility model relates to blower fan, particularly the cartridge type blower fan.
Background technique:
Axial-flow blower is widely used in ventilating and the cooling place at present, axial-flow blower is blade and wheel hub composition impeller normally, the drive motor output shaft assembling of impeller and blower fan, by the rotation of motor driving impeller, by the air pressure attenuating of blade, air moves to blower fan continuously, then, fan blade rising pressure promotes the rear of air from blower fan forwards, and the air-flow of generation is realized ventilating and cooling.The air quantity of air-flow is big more, the heat dissipation potential of blower fan is also high more, but too high rotating speed can cause noise big simultaneously, and the ventilation and the amount of cooling water of different occasions or same occasion different times needs neither be constant, can not realize the adjustment of air quantity by the structure of adjusting blower fan.The axial-flow blower that is used to cool off the place more requires to have certain low temperature tolerance characteristics, and present axial-flow blower is after a period of time is used in places such as freezer, water frosting easy to hang on the blade, even freeze, use the motor load to increase, blower fan self energy consumption is big, and efficient is low.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned not whole problem, and a kind of low temperature resistant energy-efficient tubular axial-flow blower is provided, compact structure, and air quantity is adjustable, and the efficient height is low temperature resistant.
The technological scheme that the utility model is adopted for achieving the above object is: low temperature resistant energy-efficient tubular axial-flow blower, mainly form by water conservancy diversion air duct, impeller, motor, water conservancy diversion end cap, impeller is made up of blade and wheel hub, vanes fixed is equipped with coupling shaft, have axis hole on the wheel hub, coupling shaft is installed in the axis hole, and impeller is fixedly mounted on the motor by packing ring, lock washer, impeller termination fixed installation water conservancy diversion end cap, motor is fixed on the air duct by electric machine support.
Described blade is that nylon adds carbon fibre material global formation blade, and wheel hub is an aluminum alloy material integral die-cast moulding wheel hub.
Described blade surface is printed on quick-fried dried lacquer layer of UV or resin emulsion paint sprayfused coating.
Described vane airfoil profile is pressed the aerial blade shape of aerodynamics principle design in the aviation flight aspect theory.
Described wheel hub is that last wheel hub and lower hub are formed, and last wheel hub and lower hub have semi-circular axis hole, and last wheel hub and lower hub are fastened and connected and by bolt.
Be installed with terminal box on the described air duct.
The utility model blade can carry out angular adjustment in the axis hole of last wheel hub and lower hub, choose different angles according to practical situations, can reach different air quantity, blast requirements.Blade adopts nylon to add the carbon fibre material one piece and finishes manufacturing, and wheel hub adopts aluminum alloy material integral die-cast moulding weight light than the metal mold blade, reduces motor load, reduces no worker's loss.Blade surface at global formation carries out the water transfer process, quick-fried dried lacquer of UV or resin emulsion paint spraying are used in the surface, make the very smooth adhesion in surface extremely low with water, vapour, compare on worst cold case lower blade surface with metal blade and to be difficult for frosting, do not increase the motor reactive loss, minimizing vibrations, reduction noise help environmental protection.Vane airfoil profile designs by aviation flight aspect theoretical aerodynamics principle, thereby makes the efficient of blade obtain to significantly improve, and greatly reduces air horsepower consumption and compares saving power 10%～30% with similar products at home and abroad.
