Dust collector centrifugal fan

G4-73 and Y4-73 series ventilation and induced draft fans are suitable for the ventilation and induced draft fan systems of 2~670T/h steam boilers in thermal power plants.
It can also be used for mine ventilation and general ventilation without other special requirements; Mainly used to meet the needs of large air flow applications, low noise and high efficiency.
They can transport clean gas, dusty gas, flammable gas, corrosive gas, powder or granular materials at normal temperature or high temperature.
Typical applications include: building ventilation, mine ventilation, smoke evacuation, drying, clinker cooling, transport of gas, transport of lightweight materials, blasting and drafting of industrial boiler systems, and supply of air to kiln systems/incinerator systems and induced air, air purification equipment, industrial dust collector systems, etc.
In addition to the industrial system, it is also frequently used in agriculture and civil applications and the most versatile range of centrifugal fans.

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 can work stably at a high medium temperature, and can output a large gas flow with low noise when the pressure requirement is met.

The fan blade placement angle is optimized, more wear-resistant and longer service life.

The air damper can be used to flexibly adjust the pressure and flow of the fan during operation. It is also possible to select a variable frequency motor, with adjust the pressure and flow of the fan by changing the speed.

For the material of impeller and main shaft, we will choose high-strength carbon steel, low-alloy steel, high-temperature alloy steel, high temperature resistant high-strength alloy steel under different working conditions temperature and working speed, so that the impeller and main shaft still maintains a reliable strength at high temperature.

Fan systems with impeller diameters less than 1400 mm at normal temperature do not require additional bearing cooling devices, reducing users’ investment and maintenance.

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

The weld of the impeller and the main shaft are ultrasonic flaw detection to ensure that there are no welding defects and material defects to ensure strength.

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

There are a variety of accessories to choose from.
