The magnetic levitation Roots blower is not an actual product type. Roots blower and magnetic levitation blower are two types of blowers with different technical principles, and their working mechanisms and design structures are fundamentally different. Currently, there is no mature product on the market that integrates the two technologies. The following is a specific analysis:
1、 The working principle and structural characteristics of Roots blower
1. Working principle: Roots blower belongs to the positive displacement rotary fan, which rotates at a constant speed and in the opposite direction inside the cylinder through two three bladed impellers. By utilizing the small gaps between impellers and between impellers and the casing, a volume change is formed to achieve gas suction, compression, and discharge.
2. Structural features:
Mechanical transmission: using gears or belts for transmission, there is mechanical contact and friction.
Lubrication system: Regular maintenance of lubricating oil is required to ensure the normal operation of bearings and gears.
Vibration and noise: Due to mechanical friction and clearance changes, vibration and noise are generated during operation.
2、 Working principle and structural characteristics of magnetic levitation blower
1. Working principle: The magnetic levitation blower is based on magnetic levitation bearing technology, which uses electromagnetic force to suspend and rotate the rotor at high speed, driving the impeller to achieve gas delivery.
2. Structural features:
Contactless transmission: The rotor and bearings have no mechanical contact, resulting in frictional losses.
No lubrication system: No need for lubricating oil, low maintenance cost.
Low vibration and noise: Smooth operation with significantly reduced vibration and noise.
3、 Technical differences and product positioning
1. Technical route: Roots blower relies on mechanical transmission and volume change, while magnetic levitation blower adopts electromagnetic suspension and high-speed rotation technology. The two technical routes are different and difficult to directly integrate.
2. Application scenarios:
Roots blower: suitable for low-pressure, high flow scenarios such as pneumatic conveying, sewage treatment aeration, etc.
Magnetic levitation blower: suitable for high-pressure and high-efficiency scenarios, such as cement plants, chemical industries, etc.
4、 Market Status and Industry Trends
1. Market situation: Currently, there is no product type of "magnetic levitation Roots blower" on the market, and the two belong to different technical fields.
2. Industry trend: With the maturity of magnetic levitation technology, the advantages of magnetic levitation blowers in energy conservation and environmental protection are gradually emerging, and they may replace traditional blowers in more fields in the future.
