What are the advantages of installing magnetic levitation blower in subway tunnel?

The installation of magnetic levitation blower in subway tunnel has many advantages, such as high efficiency, energy saving, low noise, environmental protection, simple maintenance and so on, as follows:

Efficient and energy-saving: The magnetic suspension blower adopts magnetic bearing technology, which eliminates the energy loss caused by mechanical friction. At the same time, it is equipped with high-efficiency permanent magnet synchronous motor, and the impeller is directly connected with the shaft, so the power transmission efficiency can reach 100%, which can save energy by more than 30% compared with the traditional Roots blower, and can effectively reduce the energy consumption cost of subway operation.

Low noise and environmental protection: Because there is no mechanical friction, the main noise when the fan rotates comes from the air flow, and the overall noise is usually less than 80dB, which is greatly reduced compared with the traditional fan noise and can reduce the noise pollution to the subway staff and the surrounding environment.

Low maintenance cost: the magnetic bearing does not need lubricating oil, which saves the maintenance work such as adding lubricating oil regularly. The daily maintenance only needs to replace the air filter at the air inlet according to the prompt of the fan, which is simple and convenient to operate and can reduce the maintenance cost and workload.

Stable and reliable operation: the magnetic bearing can monitor and adjust the position of the rotor in real time, ensure that the rotor is always in a stable suspension state, make the fan run more smoothly, reduce the damage to the equipment caused by vibration and other factors, and also reduce the impact on surrounding equipment and buildings.

Long service life: the magnetic suspension blower has no mechanical wear, which reduces the worn parts of the equipment, and its service life can generally be more than 20 years. Compared with the traditional blower, its service life is greatly increased, which can reduce the frequency of equipment replacement and reduce the overall cost.

Convenient installation: Magnetic suspension blower is a box structure, which can be installed on a horizontal road surface by using self-balancing technology and active vibration reduction design, without special installation foundation, which can save installation time and cost.

High degree of intelligence: usually equipped with advanced control system, it can realize remote monitoring and operation, monitor the running state of the fan in real time, and has the functions of fault early warning and automatic protection, which improves the reliability and safety of the equipment and is convenient for managers to maintain and manage.

Strong adaptability: The magnetic suspension blower can run stably in a wide range of rotating speed, can adapt to different working conditions and load changes, has a wider adjustment range for air volume and wind pressure, and can better meet the complex ventilation needs in subway tunnels.
