What type of wind turbine is a Roots blower in Thailand
introduction
Roots blower is a widely used fan equipment in the industrial field, known for its unique structure and working principle. This article will provide a detailed introduction to the types, structures, and working principles of Roots blowers, helping readers better understand their characteristics and applications.
Types of Roots blowers
Roots blowers are mainly divided into the following types:
1. * * Two blade Roots blower * *: The rotor of a two blade Roots blower consists of two blades, which have a simple structure and are suitable for low-pressure and low wind volume applications.
2. Three leaf Roots blower: The rotor of a three leaf Roots blower consists of three blades, which have a complex structure and are suitable for high-pressure and high air volume applications.
3. * * High pressure Roots blower * *: High pressure Roots blower can provide high pressure, usually above 58.8kPa, suitable for occasions that require high-pressure gas.
4. * * Low pressure Roots blower * *: Low pressure Roots blower can provide lower pressure, usually below 9.8kPa, suitable for occasions that require low-pressure gas.
Structure of Roots blower
The Roots blower is mainly composed of the following parts:
1. * * Shell *: The shell is the main structure of the fan, usually welded from cast iron or steel plates, and has good strength and rigidity.
2. * * Rotor * *: The rotor is the core component of a fan, usually composed of two interlocked blades, and the material of the rotor is usually cast iron or aluminum alloy.
3. * * Bearings * *: Bearings are used to support rotors and ensure their smooth operation, usually using rolling bearings or sliding bearings.
4. * * Gears * *: Gears are used to synchronize the motion of two rotors and ensure their meshing accuracy, usually using high-precision gears.
5. * * Sealing device * *: Sealing devices are used to prevent gas leakage, usually using mechanical seals or packing seals.
Working principle of Roots blower
The working principle of Roots blower is based on volumetric compression, and the specific process is as follows:
1. * * Inhalation process * *: As the rotor rotates, the volume between the two rotors gradually increases, creating negative pressure and inhaling gas.
2. * * Compression process * *: As the rotor continues to rotate, the volume between the two rotors gradually decreases, and the gas is compressed.
3. Exhaust process: When the rotor rotates to an angle, the volume between the two rotors reaches and the gas is discharged.
Application scenarios of Roots blower
1. * * Sewage treatment * *: Roots blowers are commonly used in sewage treatment plants to supply oxygen to aeration tanks, which can effectively improve the efficiency of sewage treatment.
2. * * Pneumatic conveying * *: In industries such as grain and chemical, Roots blowers can be used in pneumatic conveying systems to achieve rapid material conveying.
3. * * Aquaculture * *: In aquaculture farms, Roots blowers can be used to aerate, increase the dissolved oxygen content of water, and promote fish growth.
conclusion
Roots blower, with its unique structure and working principle, has become an important equipment in the industrial field. By understanding its type, structure, and working principle, one can better select and use fans to improve production efficiency.
