What Is A Centrifugal Fan? – Complete Guide
A centrifugal fan is one of the most efficient fans on the market today. Most people think of a centrifugal fan as just a fan; its intricacies are not exactly common knowledge.
This complete guide will tell you everything you need to know about centrifugal fans. You might be wondering ‘What is a centrifugal fan? What are centrifugal fans used for? What are the different types of fans?
We will answer these questions and more. We’ll also highlight several useful videos from HVAC experts who break down these concepts in great detail.
A centrifugal fan or centrifugal blower is a pump or motor that moves air. It pulls the air inside the blower and then pushes it out at a 90o angle. The two main components of a centrifugal fan are the motor and the impeller. An impeller sucks or pulls air, in contrast to a propeller which pushes air.
Some fans can pull and push air at lower than a 90o angle; these fans are called mixed flow fans.
Centrifugal fans can either have no exterior housing or structure to offer protection or they can be built with some protective housing.
As shown in the video below, there are five different types of centrifugal fans, which differ based on the type and shape of the fan blades.
Backward curved blades
Backward inclined blades
Backward inclined aerofoil blades
Forward curved blades
Know the Working of an Axial Fan
Across industries, there are various machines and devices both electrical and electronic, which are designed for 24/7 working. As a result, they heat up, and if this exceeds the limits set, the device may be damaged which will result in halted production. To avoid machine failure due to excess heat, AC or DC industrial fans are used. There are various types of fans such as centrifugal, axial, and so on. An axial fan is a type of industrial fan which helps cooling of machines and devices. They facilitate parallel air flow to the rotor shaft, which offers ventilation to the device and prevents overheating. This post discusses the working and uses of AC and DC axial fans.
Why high pressure fans are often used in pig barns
Various ventilation techniques are used to raise the air quality in pig barns to a desired level. Many of these techniques use a specific type of fan to facilitate the required air movement. A frequently used fan in pig barns is the High Pressure Fan. In this article, we will tell you more about High Pressure Fans and why these fans are often used in pig barns.
Industrial centrifugal fan plays an important part in cement production line, especially with the development of preheater pre decomposition kiln, even more important. At the same time the fan is also more power consumption of cement equipment, according to statistics, the total power of about 15% of the total installed capacity of cement plant.
What is the role of fan in the cement production line?
High temperature fan: the equipment through the raw material and clinker, Inlet temperature can reach 320℃, is to pre-heater vacuum pumping, the raw material in the preheater down the process of full preheating (material to go down, hot air to go up), while the tower pull over the wind to the raw material mill for Heat, so its shutdown will directly lead to raw material grinding system and firing system shutdown.
Cement plant kiln exhaust fan: to make high-temperature fan and vertical mill system exhaust out of the dust after the row to the atmosphere.
Kiln centrifugal blower: it is similar to cement plant kiln exhaust fan, high energy saving,less power.
Dust collector fan: fan is the main equipment in dust removal systems, offer the power source of the whole systems, and overcome the resistance loss caused by the air flow in the system.
A suction axial flow fan is a type of industrial fan used to cool machines and equipment which heat up after use. Axial flow fans are the type of compressor, which produces airflow parallel to the axis, thus the name. These fans are equipped with impellers, which suck the air in and discharge in the same direction of the axis.
