Description
Technical field suspension vertical pivot blower fan is related to a kind of ventilation equipment.
The impeller shaft for the blower fan that background technology uses at present is horizontal positioned, and due to the effect of gravity, draught fan impeller turns
There is certain frictional force between rotating shaft and bearing when dynamic.
The purpose of content of the invention the utility model suspension vertical pivot blower fan is to propose a kind of blower fan of zerofriction force.It is
By support, motor, shaft coupling, air outlet, Blower Housing, lower magnetic group, upper magnetic group, upper conical concave surface magnetic group, upper conical convex surface magnetic
Group, fan, air inlet, heat emission hole, upper reinforcing plate, fan shaft, impeller, lower reinforcing plate, inferior pyramidal concave surface magnetic group, inferior pyramidal convex surface
What magnetic group and safety net formed, it is characterised in that：Blower Housing is set above support, motor is provided with below support, in wind
Upper reinforcing plate is set on the upside of casing body, lower reinforcing plate is set on the downside of Blower Housing, magnetic group and upper under being set in upper strengthening version
Taper concave surface magnetic group, inferior pyramidal concave surface magnetic group is set below lower reinforcing plate, fan shaft is placed vertically, and impeller is provided with axle,
Upper magnetic group, upper conical convex surface magnetic group and fan are provided with the top of axle, is provided with inferior pyramidal convex surface magnetic group in the lower section of axle, under axle
End is connected by shaft coupling with the axle of motor, lower magnetic group, on set in magnetic group, upper conical concave surface magnetic group, upper conical convex surface magnetic group
There is heat emission hole, the air inlet of blower fan is located above housing, safety net is provided with above air inlet, the air outlet of blower fan is located at housing
Left side.
Downward power suffered by fan shaft has the gravity of object and inferior pyramidal concave surface magnetic group on axle and axle convex to inferior pyramidal
The repulsion of face magnetic group, the upward power suffered by fan shaft have lower magnetic group to the repulsion of upper magnetic group and upper conical concave surface magnetic group to upper
The repulsion of taper convex surface magnetic group, in fan operation, fan also has upward lift, and upward power is mutually put down with downward power
During weighing apparatus, fan shaft is in suspended state.
When fan operation, in the presence of fan, air is forced into from air inlet, and from air-out under impeller effect
The double action of mouth discharge, fan and impeller is substantially that two-stage blower fan is in series.When fan forces air into air inlet, have
Partial air flows through from heat emission hole, enables magnetic group cooling.
Because the center of gravity of fan shaft is in the lower section of upper magnetic group, when above upper magnetic group is suspended in lower magnetic group, fan shaft is in
Stable vertically depending state, under upper inferior pyramidal convex surface magnetic group and the effect of taper concave surface magnetic group, fan shaft has middle trend, wind
Arbor is maintained on the magnetic group center line of inferior pyramidal concave surface.
During fan operation, fan shaft is in vertical suspended state, will not produce frictional heat.
