Magnetic suspension blowers have the following characteristics in the aquaculture industry:

1. Energy saving and high efficiency: the use of magnetic bearings, no contact, no mechanical friction, and no variable speed adjustment, reducing energy loss. At the same time, it can be adjusted according to the working conditions, compared with the traditional fan energy saving about 30%, energy saving and emission reduction effect is significant. For example, a 1kW maglev centrifugal blower can meet the oxygen supply requirements of 1.5 tons of seafood. Take a 20,000 tons industrial sewage treatment plant, the use of magnetic levitation blower a year to save electricity in 800,000 KWH, saving nearly 500,000 yuan.

2. Low noise: Using self-balancing technology, the vibration of magnetic bearings is an order of magnitude smaller than that of traditional bearings; At the same time, the active shock absorption design is adopted, the operation is stable, the body vibration is small, and the fan noise is usually below 80dB.

3. Easy to control: it can monitor the working status of the fan in real time to achieve the control of air volume, air pressure, speed and other modes. If an exception occurs, remote maintenance and adjustment are also supported.

4. High cooling efficiency: The cooling system adopts a combination of air cooling and water cooling, which can effectively control the motor temperature and realize the start and stop of the fan at any time.

5. Maintenance-free: integrated skid structure, daily operation without mechanical maintenance, just replace the filter.

However, magnetic levitation blowers also have some disadvantages, such as the use of magnetic levitation bearings to support the load, requiring a very complex control system and sensors to accurately monitor and control; Bearing characteristics will fail during power outage, and subsidy measures are needed, such as subsidized bearings equipped with subsidized batteries or using grease, etc., and the maintenance cost is high when the bearing system fails. However, at present, some enterprises have mastered the "dual maintenance self-electricity" technology, which can solve this problem.

In practical application, the magnetic suspension blower can be used to aerate the sewage tank, so that the biological active matter in the sewage treatment tank can fully contact with the material in the sewage, so as to achieve the purpose of decontamination; It can also be used in material gas conveying, such as cement factory, lime factory, chemical, food and other industries of industrial raw materials, dust, food raw materials and other pneumatic conveying.
