Explain the working principle of Roots blower in one minute
The working principle of Roots blower can be briefly explained in one minute as follows:
Roots blower is a type of positive displacement fan that mainly relies on the relative motion of two blade rotors (usually three bladed impellers) inside the cylinder to compress and transport gas. The specific process includes:
1. Impeller rotation: The motor drives one of the impellers to rotate, and through the action of the synchronous gear, the other impeller will rotate synchronously at the same speed and in the opposite direction.
2. Gas suction and compression: Due to the gap between the impellers, a vacuum is formed at the inlet during rotation, and air is sucked into the inlet chamber under atmospheric pressure. As the impeller continues to rotate, the air in the intake chamber is carried to the exhaust chamber, and at the same time, because the impellers in the exhaust chamber mesh with each other, the air is squeezed out.
3. Gas exhaust: Through continuous inhalation and compression, air is transported from the inlet to the outlet on site, completing the entire gas transportation process.
4. Roots blowers have the advantages of simple structure, easy manufacturing, low vibration, low noise, long-lasting performance, long-term continuous operation, high volume utilization rate, high volume efficiency, compact structure, and flexible installation methods. They are widely used in various fields such as aquaculture oxygenation, sewage treatment aeration, cement conveying, pneumatic conveying, flue gas desulfurization and denitrification, ventilation, etc.
In summary, the Roots blower achieves continuous gas suction, compression, and discharge through the relative motion of two impellers. For more details, it is recommended to consult relevant literature or consult machinery.
