What is a Roots blower
Roots blower, also known as Roots blower, is a type of positive displacement fan widely used in various industrial fields. Its name comes from its inventors, the American brothers Philonder and Francis Roots, who obtained a patent for this type of wind turbine in 1854. The main function of a Roots blower is to transport gas by rotating two interlocked rotors, thereby achieving gas compression and transportation.
Working principle
The working principle of Roots blower is relatively simple but very effective. It is mainly composed of two interlocked rotors that rotate inside the casing. When the rotor rotates, gas is drawn into one side of the fan, then pushed towards the other side by the rotational motion of the rotor, and finally discharged. Due to the design of the rotor, gas is not compressed when passing through the fan, but is continuously transported out. This design makes Roots blowers very useful in situations that require large amounts of gas delivery.
Main components
1. * * Rotor * *: The core part of a Roots blower, usually composed of two interlocked rotors. The shape of the rotor is usually three or two bladed, which can effectively reduce gas reflux and noise.
2. * * Shell *: The shell is the outer casing of a Roots blower, usually made of cast iron or steel. Some processing is carried out inside the casing to ensure that the rotor can rotate smoothly.
3. * * Bearings * *: Bearings are used to support the rotor and ensure its smooth rotation. High quality bearings can extend the service life of the machine.
4. * * Seals * *: Seals are used to prevent gas leakage and ensure the efficiency of the fan.
5. * * Drive device * *: Usually driven by an electric motor or diesel engine, providing power to rotate the rotor.
application area
Roots blowers have a wide range of applications in many industrial fields, including but not limited to:
-Wastewater treatment: In wastewater treatment plants, Roots blowers are used to provide oxygen, promote microbial growth, and accelerate the wastewater treatment process.
-Pneumatic conveying: In industries such as grain, cement, and chemical, Roots blowers are used to transport powder or granular materials.
-Aquaculture: In aquaculture, Roots blowers are used to increase the oxygen content in water and improve breeding efficiency.
-Vacuum packaging: In the food and pharmaceutical industries, Roots blowers are used for vacuum packaging to extend the shelf life of products.
summarize
Roots blower is a reliable gas conveying equipment widely used in various industrial fields. Its simple and effective working principle makes it perform well in situations that require large amounts of gas delivery. By understanding the basic structure and working principle of Roots blowers, we can better comprehend their applications and importance in various industries.
