High-speed encapsulated fan

Magnetic levitation blower is a mechanical device for transporting gas. It uses core technologies such as magnetic levitation bearings, 3D flux impellers, high-speed permanent magnet synchronous motors, high-efficiency variable frequency drive, and intelligent monitoring and control. During startup, it first circles and then rotates, operating without friction and without the need for lubrication. The 3D impeller is directly connected to the rotor, resulting in no loss of transmission. It is a high-tech green product, energy-saving and environmentally friendly.

The magnetic levitation blower uses non-contact and frictionless magnetic levitation bearings and high-speed, high-power magnetic synchronous motor to directly drive the efficient fluid impeller. It overcomes the disadvantages of traditional blowers and air suspension blowers, and offers advantages such as high efficiency, low noise, reduced errors, and no need for lubrication system. Even if the magnetic levitation bearings fail, the protective bearings in the system ensure that the high-speed rotor can stop safely without causing serious damage to the equipment.

The magnetic levitation blower is driven directly by a high-speed motor and its speed is controlled by a frequency converter. Using active magnetic levitation bearing system, it provides contactless and wear-free suspension support to the rotating internal magnetic levitation bearing through controllable electromagnetic forces. The magnetic lift bearing connects directly to the impeller, resulting in no loss of transmission. This allows for successful gas delivery while the machine suffers no internal wear, is low noise, and does not require lubrication. [1]

The function of magnetic levitation bearing is to realize the suspension shaft. It detects the position of the shaft through built-in position sensors, sends this signal to the magnetic levitation bearing control device to adapt, calculate, and amplify to obtain the control current, and then input this control current into the magnetic bearing to generate a controllable attractive force on the rotor, thus suspending the shaft.

The function of a permanent magnet synchronous motor is to drive the rotation of the rotor shaft. An adjustable alternating current is generated by a variable frequency power supply, and this alternating current enters the motor stator to create a rotating magnetic field, which in turn drives the rotor to rotate at high speed.

The function of the fan is to achieve the blowing of air. The impeller, which rotates at high speed with the rotor, pushes the air out of the solute inlet, and under the influence of the direction and pressure of the solute, the air becomes a gas at a certain flow rate and pressure, which is eventually discharged from the solute outlet, thus accomplishing the blowing function of the fan.

1. Transport of materials and gas

It can be used in industries such as cement plants, chemicals and food: application scenarios include pneumatic transport of industrial raw materials, dust and food.

2. Wastewater treatment (municipal and industrial)

It can be applied to wastewater tanks, allowing biological activity in the treatment tanks to fully interact with the substances in the wastewater, thus achieving the purpose of removing pollutants.

3. Aquaculture

By blowing air into the bottom of hydroponic ponds, the oxygen content in the water increases, which improves the survival rate of aquatic products.

4. Other industries

For example, paper mills, brewing, textiles, dairy industry, thermal power, and other industries.
