Abstract
The utility model relates to an axial-flow fan. The low temperature-resistant high-efficient energy-saving net cover axial-flow fan is composed of a wind cone, an impeller, a motor and a net cover, wherein the impeller is composed of a blade and a hub, the hub is sleeved outside the motor body in clearance fit, the blade is fixedly connected with an output shaft of the motor through a washer and astop washer, a flow guide end cap is fixed at the end tip of the impeller, the net cover is provided with an installation hole which is sleeved outside the motor and fixed on the sidewall of the motor, and the end face of the motor is fixedly equipped with a junction box. The large-diameter hub of the impeller of the axial-flow fan covers a part of the motor so that the space is effectively utilized to better compact the entire structure of the fan, cause axial size to become shorter and reduce the height of the net cover. The blade in the shape of aero impeller enhances the efficiency prominently and includes, in cooperation with short wind cone, the efficiency higher than that of domestic and oversea similar products by 10%-30%, thus realizing great reduction of the consumption of shaftpower and saving electric energy by 10%-30%.
Description
Technical field:
The utility model relates to blower fan, particularly 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.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, efficient is low, net cover type blower fan guard is fixed on the motor end face, and impeller is installed on the motor output shaft, and the blower fan volume is big and heavy.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned whole problem, and a kind of low temperature resistant energy-efficient guard axial-flow blower is provided, and compact structure, volume is little, low temperature resistant, efficient is high.
The technological scheme that the utility model is adopted for achieving the above object is: low temperature resistant energy-efficient guard axial-flow blower, constitute by air duct, impeller, motor and guard, impeller is made up of blade and wheel hub group, wheel hub is sleeved on the external and Spielpassung of motor, impeller is by packing ring, the fixedly connected motor output shaft of lock washer, and the water conservancy diversion end cap is fixed on the impeller termination, and guard has mounting hole, mounting hole is sleeved on outside the motor and is fixed on the motor side wall, motor end face fixed installation terminal box.
Described blade is that nylon adds carbon fibre material integral one-step molding blade, and wheel hub is that nylon adds carbon fibre material integral one-step molding wheel hub.
Described blade surface is printed on quick-fried dried lacquer layer of UV or resin emulsion paint sprayfused coating.
The aerial blade shape that described vane airfoil profile designs by aerodynamic principle in the aviation flight aspect theory.
Described motor is the motor of resistance to low temperature.
The large diameter wheel hub of the utility model impeller covers the part of motor, effectively utilizes the space to make the shorter guard height that reduces of the more compact axial dimension of whole blower fan structure.Improved the intensity of guard, the vibrations that reduce blower fan make blower fan work more steady, reduce noise environmental protection more.Blade and wheel hub adopt nylon to add the carbon fibre material one piece and finish manufacturing, and weight is light than the metal mold blade, reduce motor load, reduce reactive 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 the efficient that makes blade obtains to significantly improve, cooperate short air duct to use, make the most effective of blade reach 90%, efficient exceeds 10%---30% than similar products at home and abroad, greatly reduce air horsepower consumption, saving power 10%---30%.
