Product Introduction
XH-FRP-R Stainless steel centrifugal fans are mainly applicable to the ventilation system of 2-670t /h steam boilers in thermal power plants. In the absence of other special requirements, XH-FRP-R Stainless steel centrifugal fan 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 ℃.
Before the induced draft fan, dust removal device must be installed to reduce the dust content of the flue gas entering the fan as far as possible. According to the general use of power plants, the efficiency of the dust collector should not be less than 85%.

Product Characteristics
1.Ventilator and induced draft fan are made into single suction. Each have № 8-29.5 13 numbers.
2.Facing squarely from one side of the motor, the impeller rotating clockwise is called "right fan", and vice versa is left cyclone machine, "left".
3.The air outlet position of the fan is expressed by the air outlet angle of the housing.
4,the drive mode of fan is D type, all adopt elastic coupling connection.

Fan structure
Fan is mainly made up of impeller, casing, inlet, regulating door and transmission part.
1.impeller-12 tilting wing oblique blade welded to conical arc front disc and flat back disc. Because the wing blade is adopted, the main efficiency, low noise and high strength of the fan are guaranteed. Impeller by static and dynamic balance correction and overspeed operation test, so the operation is stable and reliable. The same machine number, induction fan impeller, the same structure, but different materials, generally speaking fan choose A3, draft fan choose 16Mn.
2.shell-welding cochlea form with common steel plate. The case of single suction fan is made into three different forms (8-12 housing is made into integral structure, can not be disassembled, 14-16 housing is made into two open type, and 18-29.5 housing is made into three open type). The fan and cochlear plate are thickened properly to prevent wear.
3.The inlet-convergent, streamlined inlet is made into an integral structure, which is bolted to the inlet side of the fan.
4.Regulating door-an apparatus used to regulate the flow, axially installed in front of the inlet. The adjustment range ranges from 0 degrees (all open) to 90 degrees (full closed). The position of the adjusting door is: from the inlet direction to the right side, for the right-handed fan, the lifting handle from the bottom to the top is completely closed to the full open direction, and for the left cyclone, the lift handle from the top to the pull-down is completely closed to the full open direction.
5.The main shaft of drive-drive part is made of high-quality steel. The fan adopts rolling bearing. The bearing box comes in two forms: the 8-16 integral cylinder bearing box and the 18-29.5 separate pillow bearing box. The bearing box is fitted with a thermometer and an oil level indicator (inducer only). The lubricating oil adopts 30 mechanical oil, the quantity of oil is marked according to the oil level. If dry oil is used in the 8-16 integral cylinder bearing box, an oil retaining plate shall be added to the ball side of the bearing box, and the fixed groove shall be made. The draft fan is equipped with water cooling device, therefore, it is necessary to add water mains, the water consumption varies with the temperature, generally according to 0.5-1 M 3 / h consider.
