Embodiment
Referring to figs. 1 through Fig. 7, a kind of injection type air cooling permanent-magnet speed governor provided by the invention, it is by injection cover 1, the connecting axle 11 that driver and driver both sides are connected with motor and load respectively forms, wherein, the periphery of driver is arranged at intervals with multi-disc fan blade 2, in injection cover 1 both sides, corresponding connecting axle 11 periphery is formed with fresh air inlet 12, top is formed with air outlet, driver is provided with vertically two pairs of magnetic conductive disks 10 and disk 15, magnetic conductive disk 10 is arranged on outside the axis two of driver, two disks 15 are provided with between two magnetic conductive disks 10, the connecting axle 11 that two magnetic conductive disks 10 are connected with motor and load respectively with two disks 15 connects, when driven by motor connecting axle 11 drives two magnetic conductive disks 10 to rotate, by magneticaction, two disks 15 also rotate thereupon, and then drive the connecting axle 11 be attached thereto, thus driving load.
The diameter of disk 15 is 0.6 times of magnetic conductive disk 10 diameter, fan blade 2 is fixed on the periphery of two magnetic conductive disks 10, magnetic conductive disk 10 near fresh air inlet 12 has pressure air port 9, the pressure aerofoil 8 coordinated with pressure air port 9 is had in the arranged outside of pressure air port 9 import department, two inboard disks 15 have air guide hole 17, have the first wind deflector 13 coordinated with air guide hole 17 in the arranged outside in air guide hole 17 exit.The inboard of two magnetic conductive disks 10 is provided with the second wind deflector 14.Pressure air port 9 and air guide hole 17 tilt inwards along wind direction respectively.
The air outlet place of injection cover 1 is provided with the dividing plate 3 that bottom is fixed on air outlet bottom, air outlet is separated into the air exhaust passage 4 of bottom and the injection passage 5 on top, air exhaust passage 4 is connected with the first row air port 16 of injection cover 1 both sides, and injection passage 5 is communicated with second row air port 7 with the increasing negative pressure window 6 be arranged on injection cover 1.The window leaf 18 that increasing negative pressure window 6 is arranged by polylith tilting is formed.
The present invention operationally, along with the rotation of motor, is pressed into air port 9 by the pressure aerofoil 8 on magnetic conductive disk 10 after air sucks injection cover 1 by the fresh air inlet 12 of injection cover 1 both sides and enters working chamber between magnetic conductive disk 10 and disk 15.Again because the rotation of magnetic conductive disk 10 and disk 15 makes the part of the air between magnetic conductive disk 10 and disk 15 in working chamber enter the working chamber between two disks 15 from the air guide hole 17 of disk 15, then discharge the working chamber between two disks 15 by the first wind deflector 13 on disk 15; Another part then discharges the working chamber between magnetic conductive disk 10 and disk 15 by the second wind deflector 14 on magnetic conductive disk 10.Leave the difference of air according to air-flow velocity of working chamber, the air that flow velocity is low directly leaves injection cover 1 from injection cover 1 top air exhaust passage 4; The air of high flow rate is then introduced injection cover from injection air channel 5 part from increasing negative pressure window 6, injection effect is produced through increasing negative pressure window 6, thus increase the inspiratory capacity of injection cover 1 both sides fresh air inlet 12, separately some is discharged from second row air port 7, reaches the object of control temperature.
