Centrifugal fans are a common type of mechanical equipment widely used in many fields, such as industry, construction, medical, aviation, etc. The composition of a centrifugal fan includes the following parts.
1. Wind blade
The fan blade is one of the most important components in centrifugal fans, which affects the speed, air volume, and wind pressure of the fan. Fan blades are usually made of metal or polymer materials, and different types and sizes can be selected according to specific needs.
2. Gearbox
The gearbox of a centrifugal fan is used to transmit the rotational torque of the electric motor to the fan blades, driving their rotation. Gearboxes are usually made of materials such as steel or aluminum alloy, which have high strength and durability.
3. Electric motor
Electric motors are the power source of centrifugal fans, and their type and power are usually related to the size and purpose of the blades. Modern centrifugal fans typically use three-phase asynchronous motors, which have the characteristics of high efficiency, low noise, and low vibration.
4. Wind pressure box
A pressure box is the outer shell of a centrifugal fan, which compresses the gas sucked in from the fan blades into high-pressure gas and then discharges it into an external pipeline or workspace. The material of the wind pressure box is usually made of steel or aluminum alloy, with surface painting or electroplating treatment, which has high strength and good corrosion resistance.
5. Import and export pipelines
The inlet and outlet pipes of the centrifugal fan are connected to the inlet and outlet of the pressure box, used to transport gas or liquid to or from the workspace. These pipes are usually made of materials such as steel, aluminum alloy, or PVC, and have good sealing and pressure resistance.
Centrifugal fans are widely used in various fields due to their advantages of high efficiency, reliability, and economy. The continuous improvement and enhancement of components also enable them to have higher performance and functionality, meeting the needs of different users.
