Coupling Driving Efficient Energy-Saving Centrifugal Flow Blower
Fan
Introduction
Mainly to meet the dust emission requirements of the electric arc
furnace exhaust gas purification equipment, improve the workshop
environment, to ensure that the dust concentration in the electric
furnace working area meets the “sanitary standards for industrial
enterprises”, and can also be used in various occasions with the
same functional requirements.
The 5-12 series centrifugal flow fan is an enhanced version of the
5-11 series medium pressure centrifugal fan.
It has a larger output flow than the 5-11 series. The centrifugal flow fan is also used to transport a variety of common gases and hard
materials in the industrial field, the application object is
exactly the same as 5-11 series fan.
Mainly circulating fluidized bed system, smoke exhaust, material
drying, industrial dust collector / filtration system, flue gas
desulfurization, flue gas denitrification, industrial boiler
induced air, cement production line, industrial waste heat recovery
device, mineral powder sintering ( sintering machine), Coke
production (coking furnace), etc, is especially suitable for
various harsh conditions such as high temperature, wear and
corrosion.

Advantages and Features
1. It is capable of outputting a higher outlet pressure while
providing more gas flow with lower noise. Stable operation at
higher media temperatures.
2. The Centrifugal Flow Blower Fan's speed can be flexibly set by matching different pulley diameters to
make the fan run at the highest efficiency point and reduce energy
waste.
3. Motor sliding guides are provided for easy tensioning of the
belt to reduce energy loss due to belt slack.
4. The Centrifugal Flow Blower Fan's bearing housing is reserved for temperature and vibration sensor
mounting positions, for convenient to install the fan operation
monitoring device.
5. Use liquid lubricant, it is not necessary to open the bearing
housing to replace and fill the oil. The bearing housing is
provided with an observation window for easy observation of the
quality and stock of the lubricating oil.
6. The Centrifugal Flow Blower Fan's bearing housing uses a labyrinth mechanical seal, a unique Leak
proof oil design inside, a vent hole at the top, and a sealant on
the joint, completely eliminating the possibility of oil leakage in
the bearing housing.
7. The Centrifugal Flow Blower Fan's impeller is annealed to completely eliminate the internal stress
generated during welding, ensuring that the impeller does not
undergo creep and cracks.
8. The Centrifugal Flow Blower Fan's impeller is subjected to a high standard of dynamic balance
correction to ensure stable operation of the fan.
9. After the production is completed, all products are tested for
running and vibration values for reliable operation.
