Air suspension blower
单级离心式叶轮 Single-stage centrifugal impeller for air suspension blower
The impeller can be made of AL7075 (high-strength aviation aluminum), Ti, SUS and other materials. It has excellent wear resistance and deformation resistance, and its service life is more than 30 years. The impeller and the motor are directly connected, and the power transmission efficiency is 97%. Impeller casting can be carried out according to different needs, and specific operating conditions can be obtained. The design adopts the frequency conversion adjustment method instead of the guide blade adjustment method, so that the adjustable range of the blower is wider.
Oil-free air suspension bearing
Air suspension bearings mainly include radial bearings and thrust bearings. There is physical contact between the rotating shaft and the bearing before starting. The rotating shaft and the bearing move relative to each other during starting to form a hydrodynamic field. This hydrodynamic force forms a buoyant force in the radial bearing. The buoyancy force makes the rotating shaft in a suspended state and achieves the purpose of free rotation. This kind of bearing is different from the traditional ball bearing. There is no physical contact point between the rotating shaft and the bearing during operation, so no lubricant is needed, the energy loss is extremely low, and the efficiency is extremely high. It is suitable for various working environments. This technology can be applied to high-power high-speed machines with speeds up to 100,000 rpm. After rigorous testing, the number of starts of the bearing can reach more than 20,000 times, which fully meets the design and practical application requirements.
Ultra-high-speed FM motor
BLDCM permanent magnet brushless ultra-high speed motor is one of the latest motors in the world today with the development of permanent magnet material technology, semiconductor technology and control technology. During operation, the rotary shaft achieves high-speed operation with 20,000-200,000 revolutions, and the efficiency of the engine can reach 97%. The permanent magnet brushless ultra-high-speed motor is also equipped with a digital control speed regulating device, and the system control is simple. High speed, no vibration, low noise, small size, simple structure, high efficiency and energy saving, small electromagnetic radiation, is currently the most energy-saving green environmental protection motor
