Industrial boiler blower

Model Number: GY4-68 Brand Name: Tong Tian Key Specifications/Special Features: GY4-68 type centrifugal induced draft fan is suitable for thermal power plant boiler steam under 230 t/h boiler in flux, induced draft fan series.When no other special requirements, the G4-68 type can also be used for mine ventilation and general ventilation.The ventilator transmission medium is air, the highest temperature should not exceed 80 ℃,Induced draft fan for flue gas conveying medium, the highest temperature should not exceed 250 ℃.In front of the induced draft fan, must be equipped with dust removal efficiency of not less than 85% of the dust removal device, the lower the fan in the flue gas dust content, in order to improve the service life of the fan.1, both for single suction fan and induced draft fan inlet, have № 8, 9, 10, 11, 11.2, 12.5, 14, 16, a total of seven immediately.2, each fan rotation can be made into right and left two types.From motor end face fan impeller according to clockwise, known as right-hand fan, expressed as a "right"Counterclockwise rotation of the impeller is called left cyclone machine, expressed as a "left".3, export position with casing outlet Angle of the fan said, "right" fan can be made from the "left" 0 °, 45 °, 90 °, 135 °, 180 °, 225 ° from six angles.4, the transmission mode of the fan are D-type, motor and fan connection with elastic coupling straight league transmission.

The two fan is mainly composed of impeller and casing, air inlet, damper, and driving group.

1, the impeller - by 12 backward of airfoil blade welding arc conical wheel cover and tablet roulette.
Induced draft fan impeller in the solid body, the head of the blade and easy to wear increase welding wear-resisting material, improve the service life of the blade.
Impeller has been static, dynamic balance test, to ensure smooth operation.

2, chassis - casing is worm form with an ordinary steel plate welded together.
Single suction fan casing made of two different forms: № 8 ~ 12.5 chassis is made of the whole structure.
A quarter of the № 14, 16 cases can be torn down.
For induced draft fan, above the scroll plate with the ash door open, more appropriately at the same time, in the case of suit wear and prolong service life.

3, - for ShouLianShi inlets, streamline the overall architecture of the bolted side entrance to the chassis.

4, adjust the door - used to adjust the size of the fan flow device.
№ 8 ~ 12.5 consists of 13 trailers distinguish the blade, both axial installed in front of the inlet, the adoption of the structure of the external drive, rotating flexible and convenient.
The adjusting range is from 90 ° (full close) to 0 ° (full open).
Adjust the door pull put the position, from the air inlet direction, on the right.
