Roots blower and magnetic levitation blower: comprehensive analysis of advantages and disadvantages
Roots blower and magnetic levitation blower each have their own advantages and disadvantages. The following is a detailed comparison of these two types of blowers:
1、 Roots blower
advantage
1. Simple structure: The Roots blower has a relatively simple design, making it easy to maintain.
2. Wide pressure range: Roots blower has a wide pressure range, with a single-stage pressure of up to 98Kpa, which can meet the needs of most working conditions.
3. Constant air volume: Roots blower has the characteristic of forced air supply, and the air volume is relatively constant. When the pressure is unstable, the air volume will not be affected.
4. Price advantage: Compared with magnetic levitation fans, Roots blowers are more affordable and suitable for use by small and medium-sized enterprises.
5. Reliable operation: The Roots blower operates stably, with a gap of 0.2-0.5mm between the rotor and the transfer hand, as well as between the rotor and the housing, without friction, allowing the airflow to contain dust.
shortcoming
1. Loud noise: When air flows through the outlet of the fan, it will produce a loud noise, and it is necessary to install mufflers and soundproof covers to reduce the noise.
2. High energy consumption: Ordinary Roots blowers consume a lot of energy, although there are some energy-saving Roots blowers on the market, the overall energy consumption is still relatively high.
3. The service life is relatively short: Roots blowers generally have a service life of 5-8 years and require regular inspection and maintenance.
2、 Magnetic levitation fan
advantage
1. Low power consumption: Magnetic levitation fans use technologies such as magnetic levitation bearings and high-speed permanent magnet synchronous motors, which can significantly reduce energy consumption and save electricity for enterprises.
2. Low noise: The magnetic levitation fan operates without contact friction, so the noise level is low, and the overall noise can usually be controlled below 80 decibels.
3. Low maintenance cost: Magnetic levitation fans do not have mechanical friction components such as gears, bearings, etc., so they are not easy to wear and have a long service life, up to 20 years or more. Routine maintenance requires simple operations such as replacing air filters.
4. High degree of automation: Magnetic levitation fans are usually equipped with advanced control systems, which can achieve remote monitoring and operation, improving the reliability and performance of the equipment.
5. Pollution free: Magnetic levitation fans do not require lubricating oil, and there is no problem of lubricating oil leakage causing environmental pollution. The gas transported is also cleaner.
shortcoming
1. High price: Magnetic levitation fans have high technological content and relatively high research and production costs, resulting in a higher initial purchase price.
2. Complex control system: In order to achieve the control of magnetic levitation bearings and stable operation of fans, complex control systems and a large number of sensors are required, which increases the complexity and maintenance difficulty of the equipment.
In summary, both Roots blower and maglev blower have their own advantages and disadvantages. When choosing, comprehensive consideration should be given to specific usage scenarios, budgets, and requirements for wind turbine performance.
