Roots blower belongs to the category of positive displacement rotary blower. The following is a detailed explanation about Roots blower:

1、 Definition and Working Principle
Roots blower is a mechanical device that uses two or three blade rotors to rotate relative to each other inside a cylinder to compress and transport gas. Its working principle is to suck gas from the intake port and compress it in the cylinder through the small gap and rotational motion between the rotors, and then discharge it through the exhaust port.
2、 Structural characteristics
Roots blowers are usually composed of a casing, wall panels, impellers, oil tanks, mufflers, and other parts. Among them, the impeller is the core component of the Roots blower, and its shape and arrangement directly affect the performance and efficiency of the blower. The casing is used to support and protect the impeller, while maintaining a constant gap between the rotors to prevent gas leakage.
3、 Classification and Usage
There are many types of Roots blowers, which can be classified into multiple types according to different classification standards. For example, according to the number of impeller heads, it can be divided into two blade Roots fans and three blade Roots fans; According to their purposes, they can be divided into shaft kiln blowers, gasification blowers, aeration blowers, etc; According to the type of medium, it can be divided into air blower, gas blower, hydrogen blower, etc. Different types of Roots blowers have different performance and applications, and are widely used in mining, chemical, papermaking, water treatment, metallurgy, building materials and other fields.
4、 Performance characteristics
1. Forced air supply: Roots blowers have the characteristic of forced air supply, which can provide stable gas flow under low pressure.
2. Simple structure: The structure of Roots blower is relatively simple, easy to maintain and upkeep.
3. High efficiency: Under appropriate operating conditions, Roots blowers can provide high work efficiency.
4. Strong adaptability: Roots blowers can adapt to various gas media and working conditions, and have a wide range of applications.
In summary, Roots blower is a reliable volumetric rotary blower with broad application prospects and development potential.
