The power of the fan B is 55-85% of the power of the fan A, and the impeller of the fan A does relative motion with the impeller of the fan B. The utility model has the advantages of high wind quantity, high wind pressure and small starting current. The utility model is widely used for various wind exhausting and wind blowing.
Description
The utility model relates to a kind of ventilation equipment, the particularly a kind of two-way counter-rotating fan that can blow and can air draft.
Common blower fan only has the simple function of air-supply or air draft at present, and the stator blade structure is arranged, and airflow pressure is all lower, and when using with the blast blower fan with air quantity, inrush current is bigger; The two-way counter-rotating fan that can blow and can air draft is theoretic discussion research, does not have actual product so far as seen.
The purpose of this utility model is for a kind of airflow pressure height is provided, and inrush current is little, no stator blade structure, but but can air draft can blow again, the not only two-way counter-rotating fan of two-shipper running but also unit running.
The purpose of this utility model realizes by following technological scheme.The urceolus of the urceolus of blower fan A wheel hub front end and the wheel hub front end of blower fan B fixes, and leaves the space between the wheel hub of the wheel hub of blower fan A and blower fan B, and the blade of the impeller of blower fan A is 10～16 cross sections, each cross section to the setting angle of axis by 39 ° to 63 °; The blade of the impeller of blower fan B is 8～16 cross sections, each cross section to the setting angle of axis by 31 ° to 42 °; Blower fan B wheel hub width is 60～70% of a blower fan A wheel hub width; The power of blower fan B is 55～85% of blower fan A power, the impeller relative movement of the impeller of blower fan A and blower fan B.
Blower fan A is made of wheel hub, blade, urceolus, inner core, motor Diffuser, electric machine support, bearing, motor is fixed on the electric machine support, electric machine support is fixed on the urceolus, inner core is fixed on the electric machine support, vanes fixed is formed impeller on hub spindle, impeller is fixed on the motor shaft, and bearing and urceolus welding are fixing, and the end of inner core is connected with Diffuser;
Blower fan B is made of wheel hub, blade, urceolus, inner core, motor, Diffuser, electric machine support, bearing, motor is fixed on the electric machine support, electric machine support is fixed on the urceolus, inner core is fixed on the electric machine support, vanes fixed is formed impeller on hub spindle, impeller is fixed on the motor shaft, and bearing and urceolus welding are fixing, and the end of inner core is connected with Diffuser.
The utility model has adopted the blower fan of two different capacities, special different leaf blades has been fixed together, reached the way traffic that to blow and can air draft, exhaust air rate is not less than 90% of air output, the airflow pressure height of blower fan, under identical air quantity, the blast situation identical with using power, littler than general fan starting electric current, the utility model does not have stator blade, simple in structure, can be widely used in various air drafts and air-supply.
Below in conjunction with drawings and Examples the utility model is described in further detail:
