5-12 series centrifugal ventilation fan

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.

application

Centrifugal fan is widely used in the cement industry, building materials industry, environmental protection industry, metallurgical industry, power industry projects such as large-scale dust collector, industrial boilers, ventilation systems, cooling.

Structure

Drive, we usually divide the fan into:

In the process of choosing the fan, please select the appropriate fan according to the working conditions.

Features

It is capable of outputting a higher outlet pressure while providing more gas flow with lower noise. Stable operation at higher media temperatures.

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.

Motor sliding guides are provided for easy tensioning of the belt to reduce energy loss due to belt slack.

The bearing housing is reserved for temperature and vibration sensor mounting positions, for convenient to install the fan operation monitoring device.

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.

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.

The impeller is annealed to completely eliminate the internal stress generated during welding, ensuring that the impeller does not undergo creep and cracks.

The impeller is subjected to a high standard of dynamic balance correction to ensure stable operation of the fan.

After the production is completed, all products are tested for running and vibration values for reliable operation.
