Product Description:
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 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. It 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.
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 fan 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 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 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 impeller is annealed to completely eliminate the internal
stress generated during welding, ensuring that the impeller does
not undergo creep and cracks.
8. The 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.
