1、 Working principle:

Magnetic levitation blower is a new type of high-efficiency, energy-saving and environmental protection product based on the traditional blower, which applies the active magnetic levitation bearing technology and the high-speed permanent magnet synchronous motor technology.

The active magnetic suspension bearing system is the core system of the magnetic suspension blower. The rotor of the motor is fixed between two radial magnetic bearings and two axial magnetic bearings. The position of the rotor is detected by the position sensor, and the position signal is reflected to the magnetic bearing controller in real time. When the rotor is offset, the controller will adjust the magnetic field force of each degree of freedom of the magnetic bearing according to the offset of the rotor to return the rotor to the correct position.

2、 Performance characteristics:

Energy saving and high efficiency

The high-speed permanent magnet motor is directly coupled with the high-efficiency three-dimensional flow impeller; More than 30% energy saving than traditional roots blower;

Low noise

The self balancing technology is adopted. The vibration of the magnetic bearing is one order of magnitude smaller than that of the traditional bearing and there is no friction. At the same time, the active vibration damping design is adopted to ensure stable operation. The vibration of the machine body is small and the noise of the fan is about 80dB.

intelligent control

Digital signal processor, five axis displacement control and 10 axis current control are adopted. The calculation speed is 1000m per second and the time frequency is 200m / Hz. Remote maintenance and debugging are carried out.

3、 Core components:

magnetic bearing 

Five axis freedom active magnetic bearing technology is adopted to realize rotor suspension without contact, friction, lubrication and long service life by using electromagnetic force.

Magnetic levitation control technology

Digital signal processor: 5-axis displacement control, 10 axis current control, calculation speed of 1000m per second, time frequency of 200MHz. Module converter (A / D): 20 channels, 16 bits; Digital to analog converter (D / a): 4 channels, 12 bits.

intelligent control

Adjust the speed according to the needs of the project to realize the adjustment of pressure and flow: the fan has the function of surge prediction and anti surge. Save more power for users, better protect fans, and realize remote control.

Three dimensional flow impeller

Aluminum / titanium alloy, back bending design, five axis machining center high-speed milling forming, after CAE analysis, 100% X-ray flaw detection and 115% overspeed test, the variable efficiency can reach 98%.

High speed motor

The high-speed permanent magnet synchronous motor is directly coupled with the impeller to drive, completely eliminating the mechanical transmission loss. The speed is as high as 50000 rpm, and the efficiency is more than 97%.

position sensor

The inductive sensor can monitor the X, y and Z directions at the same time. The inductive sensor sends 5-100khz AC signals to the sensor probe to monitor the inductance values at different positions and obtain the position offset.

6、 Advantages of Maglev blower:

1. Energy saving advantages

Compared with roots blower, the efficiency of Maglev blower is increased by 30 ~ 40%.

Taking the 150HP maglev blower as an example, compared with the roots blower, each maglev blower can save more than 200000 kwh of electricity and more than 200000 yuan of electricity.

2. Environmental protection advantages

Maglev blower does not need lubrication, and the air conveyed is clean and pollution-free.

The magnetic bearing is completely friction free, and the blower operates with low noise, which will not affect the surrounding office and living environment.

Calculated by 150HP magnetic levitation blower, each blower can reduce about 275 tons of carbon dioxide emissions per year.

3. Adopt cutting-edge technology

High performance frequency converter is used to control the speed.

Advanced control system is adopted, multiple control modes can be selected, and the operation turntable can be monitored and controlled remotely, without personnel on site.

The fully enclosed water cooling and air cooling system is used to heat the motor to ensure that the fan is in a stable and efficient operation state and the equipment has a long service life.

Modular design, convenient and fast maintenance.

4. Low operating cost

The magnetic bearing is completely friction free, reducing the probability of product damage, and the service life of the blower can reach more than 20 years.

The magnetic suspension blower is easy to maintain and only needs to replace the filter regularly.

Maglev blower does not need lubrication system, which saves the cost of lubricating oil and cleaning.

The motor is driven by direct connection, with small volume, light weight and space saving.

Domestic production can ensure the timely supply of spare parts.
