Magnetic levitation centrifugal blower is a new type of centrifugal blower equipment that uses magnetic levitation technology to achieve contactless operation of bearings, with advantages such as efficiency, low noise, and high reliability. This article will introduce the magnetic levitation centrifugal blower from the aspects of working principle, characteristics, application fields, and maintenance.

1、 Working principle

The magnetic levitation centrifugal blower uses a magnetic field to control the rotation of the gas impeller, achieving contactless operation of the bearings, thereby eliminating the mechanical friction and wear problems of traditional centrifugal blowers. It uses electromagnetic force to generate a reverse repulsive force between the permanent magnet shaft and the impeller, causing the impeller to suspend in the air, and controls the position and speed of the impeller through electromagnetic force. At the same time, sensors are used to monitor the position and speed of the impeller, and the electromagnetic force is adjusted through the control system to maintain balanced and stable operation of the impeller.

2、 Characteristics

1. Energy saving: The magnetic levitation centrifugal blower adopts non-contact bearings, which reduces mechanical energy consumption and improves energy utilization efficiency. Compared with traditional centrifugal blowers, it has higher efficiency and lower energy consumption.

2. Low noise: Due to the lack of mechanical contact and friction, the noise level of the magnetic levitation centrifugal blower is relatively low, which can be used in environments with high noise requirements, reducing the impact on workers.

3. High reliability: The magnetic levitation centrifugal blower adopts an advanced control system that can monitor the position, speed, and working status of the impeller in real time, ensuring the safety and reliability of the system. In addition, the absence of mechanical contact also reduces the risk of wear and failure, extending the service life of the equipment.

4. Lightweight design: The magnetic levitation centrifugal blower adopts non-contact bearings, reducing the structural complexity of traditional centrifugal blowers, making the equipment more compact and lightweight, easy to install and maintain.

3、 Application field

Magnetic levitation centrifugal blower is suitable for a wide range of industrial fields, especially in situations with high requirements for ventilation, supply and exhaust. Common application areas include:

1. Pharmaceutical industry: In the pharmaceutical production process, air needs to be filtered, circulated, and dried. Magnetic levitation centrifugal blowers can provide stable airflow to ensure the cleanliness and temperature and humidity of the production environment.

2. Electronics industry: In electronic manufacturing processes such as semiconductors and photovoltaics, it is necessary to accurately control the air flow in the working environment. Magnetic levitation centrifugal blowers can provide accurate airflow control to ensure product quality and production efficiency.

3. Chemical industry: In the process of chemical production, it is necessary to discharge harmful gases into safe areas, while also controlling the temperature and humidity of the working environment. Magnetic levitation centrifugal blowers can provide gas transportation and ventilation and exhaust functions.

4、 Maintenance and upkeep

To ensure the normal operation of the magnetic levitation centrifugal blower, regular maintenance is required, including the following aspects:

1. Cleaning and maintenance: Regularly clean the impeller and filter to avoid dust and dirt accumulation, which may affect the air volume and pressure.

2. Check the power supply: Regularly check the voltage and current of the power supply to ensure stability and avoid adverse effects on the equipment.

3. Regular calibration: Regularly calibrate the control system to ensure the accuracy of impeller position and speed.

4. Troubleshooting: Once any abnormal situation is found, timely troubleshooting and maintenance should be carried out to avoid the problem from expanding and affecting normal operation.

In summary, magnetic levitation centrifugal blowers are widely used in industrial production due to their efficiency, low noise, and high reliability. By using magnetic levitation to achieve contactless operation of bearings, energy consumption and noise are reduced, and efficiency and reliability are improved. Suitable for pharmaceutical, electronic, chemical and other fields, regular maintenance is required to ensure the normal operation and service life of the equipment.
