Product Description

High strength backward aerofoil blades industrial boiler forced draught blower fan

Product Description

The 5-06 series fan can be used in the feeding system of 2-670t/h steam boiler in thermal power plants, it can also meet the requirements of the high-pressure head performance parameters of the fluidized bed furnace.
This series of fans can also be used for dust removal, mine ventilation and general ventilation systems. The blower delivers air, and the induced draft fan delivers flue gas or gas containing foreign particles.
It can be used for more than four years when the concentration of impurities is less than 200 mg/m3.
If it contains a lot of impurities, it also can be used, but it will shorten the service life.
The maximum operating temperature of the induced draft fan must not exceed 250°C.
The performance of the fan is expressed by parameters such as fan flow, full pressure, spindle speed, shaft power and efficiency.

Product Feature

Impeller:

12 pieces of backward aerofoil blades are welded between the Arc cone front plate and the flat shaped rear plate. Because of the use of airfoil blades, the fan is guaranteed to have high efficiency, low noise and high strength. The impeller is corrected by static and dynamic balance, so the operation is stable. Forced draught fan and induced draught fan of the same machine number have same impeller structure.
 

Casing:

The casing is a volute welded by ordinary steel plates.
The casing of a single suction fan is made in three different forms: The No. 8 to 12 casing is made into an integral structure and cannot be disassembled; The No. 14 to 16 casing is made into a two open structure; The No. 18~29.5 casing is made into a three open structure.
The induced draft fan and the volute plate are appropriately thickened to prevent wear.
 

Inlet:

The converging and streamlined air inlet is made into a unitary structure and bolted to the inlet side of the fan.
 

Adjustment door:

A device for regulating the flow of the fan, axially mounted in front of the air inlet. The adjustment range is from 0° (full open) to 90°(fully closed).
 

Transmission parts:

The main shaft of the transmission part is made of high-quality steel, and the 5-51 series of fans are all made of roller bearings.
The bearing housing is available in two forms: No. 8 ~ 16 uses a whole cylindrical bearing housing; No18 ~ 29.5 uses two independent pillow bearing boxes.
The bearing housing is equipped with a thermometer and an oil level indicator (only the induced draft fan). The lubricating oil uses 46# mechanical oil, and the oil quantity is implemented according to the oil level mark. When the No8-16 integral cylindrical bearing housing uses dry oil, the oil retaining plate should be added to the ball side of the bearing housing, and the fixing grooves communicate with each other. The induced draft fan is equipped with a water cooling device, so a water supply pipe must be installed. Water consumption varies with temperature, and is generally considered to be 0.5 to 1 m3/h.
