This is about Centrifugal Fan

Centrifugal fan is to rely on the input of mechanical energy, increase gas pressure and send gas machine, it is a kind of driven fluid machinery. Centrifugal fans are widely used in ventilation, exhaust and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and draft in boilers and industrial furnaces; cooling in air conditioning and domestic appliances and Ventilation; grain drying and selection; wind tunnel source and hovercraft inflatable and propulsion.

Centrifugal fan works with turbine compressor basically the same, are due to the gas flow rate is low, little pressure change, generally do not need to consider the gas volume change, that is, the gas as incompressible fluid treatment.

Centrifugal fan can be made of right-handed and left-handed two types. Faced from the motor side: impeller clockwise rotation, known as the right rotary fan; impeller counterclockwise rotation, known as the left rotary fan.

Centrifugal fan from the chassis, spindle, impeller, bearing and motor drive and other components.

Chassis: made of steel sturdy and reliable, can be sub-integral and semi-open, semi-open for easy maintenance.

Impeller: the blade, curved front plate and plate rear plate composition.

Rotor: Static and dynamic balance should be done to ensure smooth rotation, good performance.

Transmission parts: a spindle, bearing boxes, rolling bearings and pulleys (or coupling) composition

centrifugal fan

Centrifugal blowers are widely used in sewage treatment, smelting blast furnace, coal preparation plant, mine flotation, chemical gas, vacuum and other fields, can also be used to transport other special gases.


1. Compact structure: beautiful appearance, good stability, easy installation and maintenance.

2. Smooth operation: Optimized design of the impeller to reduce the axial force to a minimum, and efficient impeller, and static and dynamic balance correction, the machine running smoothly, without any damping device in the case of bearings Amplitude ≤0.04mm.

3. Low noise: blower operation, without any mechanical friction, the use of a reasonable blade-shaped line to the sound to a minimum. Centrifugal blower noise is high-frequency noise, as long as there are obstacles, can be noise, so the fan room almost no noise.

4. Oil-free machinery: Blower bearings with grease lubrication, bearing life of more than three years. Fan does not generate oil and gas during operation. Special requirements fans, with molybdenum disulfide lithium grease lubrication bearings.

5. Impeller: Impeller with a special compound linear, reducing internal leakage and improve the volumetric efficiency.

6 easy to adjust: the inlet valve to regulate flow, the outlet valve to regulate the pressure.

7. Drive: usually using a two-pole asynchronous motor, you can also use four-pole motor drive. Depending on the user grid, different voltage motors can be used.

8. Sealing: In addition to each level of import impeller impeller, the interstage and the housing at both ends with a labyrinth seal to prevent gas leaks.

9. Cooling: exhaust bearing housing has two structures, air-cooled and water-cooled, as the impeller on the level of gas compression, resulting in the exhaust casing temperature is much higher than the intake casing. In the exhaust bearing air-cooled or water-cooled device to extend the bearing life.

10. Bearing temperature control alarm: fan accessories with temperature control box, connected to the bearing through the PT100 resistance, when the bearing temperature exceeds the set temperature, the temperature control box will automatically alarm.

11. Transmission: a coupling drive, belt drive, gearbox drive three. According to different equipment and technology, choose a different transmission
