What types of centrifugal fans are there?

The centrifugal fan is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. It is a driven fluid machine. Centrifugal fans are widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and induction of boilers and industrial furnaces; cooling and cooling of air conditioning equipment and household appliances Ventilation; drying and selection of grain; wind tunnel wind source and inflation and propulsion of hovercraft, etc. Different working conditions and types of centrifugal fans are used in all walks of life. There are many ways to classify fans. Today we will talk about the various classification forms of fans.

1. According to the different uses of the fan

1. Boiler ventilation fan: The boiler fan is to add oxygen to the boiler furnace and promote combustion. The boiler induced draft fan is to extract the flue gas generated by the combustion in the furnace, so as to realize the efficient, safe and stable operation of the boiler.

2. Flue gas treatment fan: the flue gas treatment fan is to transport the dusty gas to the dust collector and discharge the purified gas into the atmosphere, so as to realize the ultra-clean emission of the flue gas treatment system.

3. High-temperature gas conveying fan: The high-temperature gas conveying fan is a special fan, which is specially used in high-temperature workplaces. Its material has strong resistance to high temperature and high pressure.

In the case of the same fan model, symbols such as "G" or "Y" will be added before the model in order to better distinguish its use. "G" stands for boiler supply fan, "Y" stands for boiler induced draft fan, C stands for dust exhaust fan, W stands for high temperature fan, M stands for pulverized coal fan, etc.;

2. Depending on the number of impellers

1. Single-stage centrifugal fan (only one impeller);

2. Multi-stage centrifugal fan (multiple impellers are installed on the same shaft);

3. Depending on the number of air inlets of the impeller: single-suction centrifugal fan (only one air inlet), double-suction (two air inlets).

3. Depending on the gas outlet pressure

1. Low-pressure centrifugal fan (total pressure less than 1000Pa)

2. Medium pressure centrifugal fan (full pressure at 1000-3000Pa)

3. High-pressure centrifugal fan (full pressure at 3000-15000Pa)

It can also be classified according to the material and model. At present, our company mainly produces centrifugal fans made of carbon steel and stainless steel. The main models are 4-73 low pressure series fans, 4-72 low pressure series fans, 5-48 medium pressure series fans, 5 -47 medium pressure series fans, 9-19 high pressure series fans, 9-26 high pressure series fans and so on.
