Shandong ChengguCGCSeries magnetic levitation centrifugal blower

CGCThe series of magnetic levitation centrifugal blowers draws on the turbine engine technology of airplanes and is a new concept of single-stage high-speed centrifugal blower. By adopting three core technologies, namely "high-speed direct connected motor", "magnetic levitation bearing" and "high-precision ternary flow impeller", a new era of high-efficiency, high-performance, low-noise, and low-energy consumption fans has been opened. The three-way flow impeller is directly connected to the rotor, with zero transmission loss. It is a long-life, maintenance free, and environmentally friendly product with an oil-free lubrication system.

Power: 22-750kW

Stress40-120kPa

The main components include high-efficiency centrifugal impellers, magnetic levitation bearings, permanent magnet synchronous motors, and dedicated frequency converters. This type of fan adopts an integrated design, with high-speed motors, frequency converters, magnetic levitation bearings, and microprocessor control panels all designed and integrated as a whole. Its core is magnetic levitation bearing and permanent magnet motor technology.

（1）High speed centrifugal impeller. The impeller is designed and optimized using the ternary flow theory, resulting in high efficiency and a wide working area; Its material is made of high-strength forged aluminum or titanium alloy, with strong deformation resistance; Made by precision machining with a CNC machining center, it has better anti-corrosion performance. According to experts from the National Fluid Laboratory, the efficiency of the impeller working point can reach85%.

（2）High speed permanent magnet synchronous motor. Install permanent magnets on the spindle of the motor to ensure spindle magnetism. The coil wound with silicon steel sheets on the stator of the motor generates oscillating magnetic force, which maintains the same speed and oscillating magnetic field during operation, achieving synchronization. The permanent magnet motor adopts magnetic levitation bearings, which have the characteristics of no mechanical friction, low noise, low vibration, and long service life. The highest speed can reach50000r/min.

（3）Magnetic levitation bearings. Through controllable electromagnetic suction, the rotating shaft is stably suspended without any mechanical resistance during rotation, resulting in high efficiency, no wear, no maintenance, no need for lubricating oil, and no oil in the air sold.

（4）Intelligent motor control system. Magnetic levitation blowers generally use vector free variable frequency control, which adjusts the frequency to control the rotation of the permanent magnet motor, thereby controlling the flow rate of the blower to meet various working conditions. The intelligent control system can predict surge and achieve on-site control, and the equipment is installedThe GPRS system can achieve remote monitoring and data transmission.
