　　Magnetic levitation blower is a mechanical equipment for transporting gases. It adopts core technologies such as magnetic levitation bearings, ternary flow impellers, high-speed permanent magnet synchronous motors, high-efficiency frequency converters for speed regulation, and intelligent monitoring and control. When starting, it first suspends and then rotates without friction or lubrication. The ternary flow impellers are directly connected to the rotor, with zero transmission loss. It is a high-tech, green, energy-saving and environmentally friendly product. The magnetic levitation blower adopts non-contact and non mechanical friction magnetic levitation bearings and high-speed high-power permanent magnet synchronous motors to directly drive the high-efficiency fluid impeller, overcoming the shortcomings of traditional blowers and gas levitation blowers. It has the advantages of high efficiency, low noise, few faults, and no need for lubrication system. Even if the magnetic levitation bearing fails, relying on the protective bearings in the system, the high-speed rotating rotor can still be safely stopped without causing serious damage to the equipment.

　　一、工作原理磁懸浮鼓風機由高速電機直接驅動，由變頻器來調速，利用主動式磁懸浮軸承系統，通過可控電磁力對內部轉動的磁懸浮軸承進行無接觸、無磨損的懸浮支撐，磁懸浮軸承與葉輪直接連接，傳動零損失，以此達到成功輸送氣體而機器內部無磨損、低噪音、無需潤滑等效果。磁懸浮軸承的功能是實現轉軸懸浮。它通過內置的位置傳感器檢測轉軸的位置信號，將此信號送入磁懸浮軸承控制器進行調理、運算和放大得到控制電流，再將該控制電流輸入磁軸承，產生對轉子可控的吸力，從而實現轉軸的懸浮。同步永磁電機的功能是驅動轉子軸的旋轉。它通過變頻電源產生頻率可調的交變電流，將此交變電流輸入電機定子即產生旋轉磁場，帶動轉軸高速旋轉。風機的功能是實現鼓風。隨轉軸一同做高速旋轉的葉輪帶動空氣從渦殼的進氣口進入，空氣在蝸殼的導向與增壓作用下成為具有一定流速與壓力的氣體，最后從渦殼的出氣口鼓出，這就實現了風機的鼓風。

　　1、 The working principle of the magnetic levitation blower is that it is directly driven by a high-speed motor and regulated by a frequency converter. It uses an active magnetic levitation bearing system to provide non-contact and wear-resistant suspension support for the internally rotating magnetic levitation bearings through controllable electromagnetic force. The magnetic levitation bearings are directly connected to the impeller, achieving zero transmission loss and successfully conveying gas without wear, low noise, and lubrication inside the machine. The function of magnetic levitation bearings is to achieve shaft suspension. It detects the position signal of the shaft through the built-in position sensor, sends this signal to the magnetic levitation bearing controller for conditioning, calculation, and amplification to obtain the control current, and then inputs the control current into the magnetic bearing to generate controllable suction force on the rotor, thereby achieving the suspension of the shaft. The function of a synchronous permanent magnet motor is to drive the rotation of the rotor shaft. It generates an adjustable frequency alternating current through a variable frequency power supply, and inputs this alternating current into the motor stator to generate a rotating magnetic field, driving the shaft to rotate at high speed. The function of a fan is to achieve air blowing. The impeller, which rotates at high speed along with the shaft, drives air to enter from the inlet of the volute. Under the guidance and pressurization of the volute, the air becomes a gas with a certain velocity and pressure, and finally blows out from the outlet of the volute, achieving the blowing of the fan.
