Magnetic levitation bearing: Magnetic levitation bearing is one of the core technologies of magnetic levitation blower, which is composed of radial bearings, axial bearings, displacement sensors, controllers and electromagnets. The displacement sensor monitors the position signal of the rotor in real time and feeds it back to the controller. The controller performs accurate calculation and amplification according to the received signal, and outputs the control current to the electromagnet. The electromagnet generates a controllable electromagnetic force to the rotor for non-contact, non-wear suspension support, to ensure that the rotating shaft is stably suspended in a predetermined position, so that the impeller can rotate at a high speed and smoothly. Magnetic bearings have the advantages of no mechanical friction, low energy consumption and long life, and their semi-permanent service life greatly reduces the maintenance cost and downtime of the equipment.

High-speed permanent magnet synchronous motor: a permanent magnet is installed on the main shaft of the motor, and the stator of the motor is wound with silicon steel sheet. When the coil is fed with alternating current, the oscillating magnetic force will be generated, so that the rotational speed of the spindle and the oscillating magnetic field are consistent during operation to achieve synchronous rotation. Permanent magnet motor adopts magnetic suspension bearing support, avoids mechanical friction, has the characteristics of low noise, low vibration and long life, the maximum speed can reach 50000r/min, can provide powerful and stable power for the impeller.

High efficiency centrifugal impeller: The impeller is carefully designed and parameter optimized using the three-way flow theory to ensure maximum efficiency of the impeller and a wider working area. The material is usually made of high-strength forged aluminum or titanium alloy, which has excellent deformation resistance and can withstand the huge centrifugal force generated by high-speed rotation. The impeller is precisely machined by CNC machining center, which not only has high precision, but also has better anti-corrosion performance. Testing by experts of the National Fluid Laboratory, the maximum efficiency of the impeller working point can reach 85%, which is one of the key components to achieve efficient blast.

Dedicated frequency converter: The dedicated frequency converter adopts space vector algorithm, which can generate high-quality high-frequency output current and accurately control the speed and torque of high-speed permanent magnet synchronous motor. By adjusting the frequency, the precise control of the rotation of the permanent magnet motor is achieved, and then the flow and pressure of the blower are flexibly adjusted to meet the needs of various complex working conditions. At the same time, the inverter also has perfect protection functions, such as over-current protection, over-voltage protection, under-voltage protection, etc., effectively ensure the safe and stable operation of the motor and the entire system.

Intelligent control system: magnetic levitation blower generally adopts no vector frequency conversion control, and intelligent control system can carry out all-round monitoring and accurate control of the operating state of the fan. It can collect and analyze the various operating parameters of the fan in real time, such as speed, pressure, temperature, flow rate, etc., and automatically adjust the operating state of the fan according to the preset program and actual working conditions. In addition, the intelligent control system also has the functions of forecasting surge, fault diagnosis, remote monitoring and so on. Through the installation of GPRS system, users can realize the remote centralized control of the fan and wireless remote transmission of data, grasp the operation of the fan anytime and anywhere, find and solve problems in time, and provide a strong guarantee for the stable operation of the fan.
