The fan has the following significant advantages:
1) Fan pressure is high, so it is especially suitable for the use of spiral pipe and with multi-tube dust collector 1-20t/h industrial boiler.
2) The draft fan is made into single suction.
3) The air outlet position of the fan is expressed by the air outlet angle of the housing. "left" and "right" can be made into 0 degrees, 90 degrees, 180 degrees three angles.
4) The drive mode of fan is C type and D type. The connection of motor and fan adopts belt wheel drive and elastic coupling direct drive respectively.Fan is made up of impeller, casing, inlet, transmission group and adjusting door.
(1) There are 16 pieces of Q345 (16Mn) backward plate blade welded between the arc cone wheel cover and the plate wheel and corrected by dynamic balance. Therefore, smooth operation, high strength and wear resistance, long service life.
(2) Casing
The cochlea shell is welded with steel plate. Rotate from "left" to "right" above NO.8.
(3)Transmission set
The spindle is made of high quality steel with ball bearing, (4.5-7.1 with low noise bearing) as a whole with two open bearing seats, self-cooled with No. 2 calcium sodium grease and wind blade, simple in structure.
(4)Air inlet
The convergent and divergent air inlet is made into an integral structure and is bolted to the inlet side of the housing.
(5)Adjusting door
Y7-41 series fans are equipped with regulating doors to regulate the flow of the fan. The fan with 3 blades and below adopts three blades, the shutter structure is simple, the closing flexible structure is simple, the No. 10 fan adopts 11 blade plum flower type structure, and the regulation efficiency is high. The structure is reliable.The adjusting door is axially installed in front of the inlet, and the adjusting range is from 90 degrees (completely closed) to 0 degree (full open). In the direction of the inlet, for the right rotating fan, the counterclockwise rotation of the lever is from full closure to full opening. For the left rotating fan, the clockwise turn of the wrench is from full closure to full open.
In order to make the regulating door work normally, it is necessary to lubricate well. Because the air temperature of the induced fan is higher, the lubricating action of the grease can still be guaranteed by using the high temperature (260 ℃) ground grease at high temperature.
