The Low Noise Drying Centrifugal Fan is to adapt to the burning of coal and smoke prevention and dust control device (1 t/h ~ 20 t/h) industrial boilers and the integrated design of total pressure, induced draft fan for boiler efficiency up to 90.5% of all air inlet conditions, performance and adapt to all can choose, but the temperature does not exceed 250 ℃. Current industrial boiler series is more, the gasification of coal quality fit and unfit quality disparity, with filter resistance is differ, the air volume and air pressure differences of induced draft fan, in order to adapt to the situation, consider the fan efficiency, in addition to the distribution of 20 t/h boiler induced draft fan for large power using D type transmission, the remaining adopts triangle (C type) transmission, so that can not only with the same number of different rotational speed to meet the requirements of the same tonnage boiler configuration of various types of dust collector, reduce the number of fan series number, but also easy to use unit according to the actual situation to change spindle speed to obtain the required ideal air volume and air pressure.
Product performance
Air flow range2417~69347m³/h
Pressure range1079~3874Pa
Speed1480~2900r/min
Product feature
The  Low Noise Drying Centrifugal fan is mainly composed of impeller, housing, air inlet, transmission part, adjusting door and other parts.
1. Impeller -- 12 pieces of rear-tilting plate blades with material of 16Mn are welded between the front plate of arc conical shape and the back plate of plate shape. After static and dynamic balance correction and overspeed operation test, the impeller is stable and reliable, with strong strength and wear resistance and long service life.
2. Chassis, with steel plate welded into volute whole, № around eight or more rotation.
3. Air inlet -- the convergent and scattered air inlet is made into a integral structure, which is fixed on one side of the air inlet of the housing with bolts.
4. Transmission -- the transmission spindle is made of high quality steel and adopts rolling bearing;№ 4 ~ 6 and fission by whole two bearing box for users to choose.When placing order, please clearly indicate, the overall structure for 30 # engine oil lubrication, fission transmission with molybdenum disulfide grease lubrication, № 8 above has oil level signal and thermometer, water-cooling device, home delivery, water consumption of 0.5 ~ 1 m3 / h, № 6 below with a fan from the cold, the transmission between the casing with two semicircle fan leaf from the cold, № 8 ~ 12.4 with two tied for bearing seat.
5. Damper, air volume, to adjust the axial loading before the air inlet, flexible rotation, the adjusting range is full open to full close, № 8 above the petal type, № 6 below the disc valve type, in order to adjust the door to work, must keep good lubrication condition, adopting expansion grease.
