Production describtion:
The air bearing centrifugal blower adopts the integrated design concept of air bearing and permanent magnet synchronous super high speed motor (20,000 rpm), abandons the gearbox accelerator and coupling and lubrication system of traditional centrifugal blower, and is the most efficient centrifugal blower in the world at present. Even after another 100 years,RAETTS air bearing blowers with national level IE4 level of energy efficiency, is still the standard of energy-saving blower.
Advantages of RAETTS air bearing blower:
1.Ultra-high Permanent Magnet Core Technology
Explorer-Series permanent magnet synchronous motors have a high efficiency of over 95% and have good cooling effects, unlike other general motors. With 15 years of motor design experience, we have developed the world's most efficient and stable PM MOTOR permanent magnet synchronous high-speed motor.
2.Air Bearing Technology
100% pure oil-free air bearing, no mechanical friction, service life can reach semi-permanent. No mechanical noise, no mechanical vibration, simply conveying air. Since 2000, it has been widely used in large and medium-sized industrial machinery. Compared with oil bearing, its simple structure can start stably at high temperature. It has the best suspension ability in permanent magnet high-speed motor and does not need a complex sensor system.
3.Aerospace Aluminum Alloy Impeller
Explorer-Series air bearing blower uses high-strength aerospace aluminum alloy impeller, design precision can reach 0.001 mm to ensure high efficiency of operation, surface treatment using hard anode and other treatment methods can also maintain high efficiency in a harsh environment.
4.Unique Motor Cooling Technology
Explorer-Series motors use a two-stage cooling structure system for better cooling and stability. The first stage is air-cooled inside the motor, and the second stage is effectively cooled in the air bearing assembly and stator of the motor. This powerful two-stage cooling system is constructed in our motor without additional auxiliary cooling equipment (externally connected forced cooling fan, etc.).
- 2 stage compression technology
The pressure below 1.2kg adopts one-stage air compression technology, and the pressure between 1.2kg and 4kg adopts two-stage air bearing compression
technology, which has very high efficiency.
Application:
RAETTS air bearing centrifugal blower is widely used in:
raw material pressure conveying (grinding or granular raw material transportation)
food and medicine processing engineering (simplified and food, medicine, etc.)
metal processing engineering (paste/non-ferrous transportation and heat treatment, sludge drying treatment),
thermal power
