磁悬浮鼓风机主要由高效离心叶轮、磁悬浮轴承、永磁同步电机和专用变频器四部分精密集成。其设计核心在于磁悬浮轴承和永磁电机技术，确保了风机的高效、静音及无磨损运行。

　　The magnetic levitation blower mainly consists of four precision integrated parts: high-efficiency centrifugal impeller, magnetic levitation bearing, permanent magnet synchronous motor, and dedicated frequency converter. The core of its design lies in magnetic levitation bearings and permanent magnet motor technology, ensuring the efficient, silent, and wear free operation of the fan.

　　高速离心叶轮

　　High speed centrifugal impeller

　　叶轮采用先进的三元流动理论进行设计，并经过参数优化，以最大化叶轮效率，拓宽其工作区域。材质上，它选用高强度锻铝或钛合金，抗变形能力强，且在数控加工中心精密加工后，防腐性能更佳。经国家流体实验室专家测试，叶轮工作点最高效率可达85%。

　　The impeller is designed using advanced ternary flow theory and parameter optimization to maximize impeller efficiency and expand its working area. In terms of material, it is made of high-strength forged aluminum or titanium alloy, which has strong deformation resistance and better anti-corrosion performance after precision machining on CNC machining centers. According to experts from the National Fluid Laboratory, the maximum efficiency of the impeller working point can reach 85%.

　　高速永磁同步电机

　　High speed permanent magnet synchronous motor

　　电机主轴上安装的永磁铁保证了主轴的磁性，而其定子硅钢片上的线圈则产生震荡磁力，与电机转速保持一致，实现同步旋转。永磁电动机与磁悬浮轴承的结合，使得它具有无机械摩擦、低噪音、低振动以及长寿命的特点，最高转速可达50000r/min。

　　The permanent magnet installed on the motor spindle ensures the magnetic properties of the spindle, while the coil on the stator silicon steel sheet generates oscillating magnetic force, which is consistent with the motor speed and achieves synchronous rotation. The combination of permanent magnet motor and magnetic levitation bearing makes it have the characteristics of no mechanical friction, low noise, low vibration, and long service life, with a maximum speed of up to 50000r/min.

　　磁悬浮轴承

　　Magnetic levitation bearings

　　通过可控电磁吸力，磁悬浮轴承能稳定地使转轴悬浮，消除旋转过程中的机械阻力，从而提高效率，实现无磨损、免维护、无需润滑油，且输出的空气不含油。

　　Through controllable electromagnetic suction, magnetic levitation bearings can stably suspend the shaft, eliminate mechanical resistance during rotation, thereby improving efficiency, achieving wear free, maintenance free, lubrication free, and oil-free output air.

　　电机智能控制系统

　　Intelligent Motor Control System

　　磁悬浮鼓风机通常采用无矢量变频控制，通过调节频率来控制永磁电机的旋转，进而调节鼓风机的流量，满足各种工况需求。其智能控制系统还能预测喘振、实现就地控制，并通过GPRS系统实现远程监控和数据传输。

　　Magnetic levitation blowers usually use vector free variable frequency control to control the rotation of permanent magnet motors by adjusting the frequency, thereby adjusting the flow rate of the blower to meet various working conditions. Its intelligent control system can also predict surge, achieve on-site control, and achieve remote monitoring and data transmission through GPRS system.

　　工艺参数

　　Process parameters

　　功率：磁悬浮鼓风机的功率范围从50kW到1WM，提供多种型号选择，满足不同用户的需求。同时，它支持多机联动控制，多台设备可协同工作，进一步提升效率。

　　Power: The power range of the magnetic levitation blower is from 50kW to 1WM, providing multiple models to meet the needs of different users. At the same time, it supports multi machine linkage control, allowing multiple devices to work together and further improve efficiency.

　　风量：风量范围从30m3/min到660m3/min，且风量变频可调。单台设备风量调节范围高达50%，可根据水质情况灵活调节风量。

　　Air volume: The air volume range is from 30m3/min to 660m3/min, and the air volume can be adjusted by frequency conversion. The air volume adjustment range of a single device can reach up to 50%, and the air volume can be flexibly adjusted according to the water quality.

　　升压：升压范围覆盖40kPa至150kPa，压力变频可调。这一设计能有效应对水位变化带来的压力波动，实现快速响应，满足存在压力变化的工艺需求。

　　Boosting: The boosting range covers 40kPa to 150kPa, and the pressure can be adjusted by frequency conversion. This design can effectively cope with pressure fluctuations caused by water level changes, achieve rapid response, and meet the process requirements of pressure changes.

　　高速永磁同步电机与叶轮直接耦合驱动，有效消除了机械传动损失，使得转速高达50000RPM，效率超过85%。在噪音控制方面，该鼓风机表现出色，噪音水平不超过85分贝，远低于人类可承受的安全噪音标准。由于缺乏机械摩擦，噪音主要来源于空气的高速流动，属于高频噪音，传播距离相对较短，易于通过管道包覆等方式进行控制。

　　The high-speed permanent magnet synchronous motor is directly coupled with the impeller for driving, effectively eliminating mechanical transmission losses, resulting in a speed of up to 50000 RPM and an efficiency of over 85%. In terms of noise control, the blower performs excellently, with a noise level not exceeding 85 decibels, far below the safe noise standards that humans can tolerate. Due to the lack of mechanical friction, the noise mainly comes from the high-speed flow of air, which belongs to high-frequency noise. The propagation distance is relatively short, and it is easy to control through methods such as pipeline wrapping.
