RAETTS Products

Experts for air suspension and magnetic levitation technologies.

air blower for fish

RAETTS air bearing blower adopts aviation turbine technology, since there is no physical friction between impeller and shaft, so it is no need to do maintenance for a long period, and the service life can reach semi-permanent. The core components are air suspension bearings, permanent magnet ultra-high-speed motors, and high-precision aviation-grade impellers,therefore RAETTS air bearing blower/compressor has the characteristic of high efficiency, low noise, and low energy consumption. They are the best choice for transforming Roots blowers.

Product Details

Many people is curious about the working principle of the maglev turbo blower:how we make it runs?At first,we need to know one working principle:when we energize the coil, it can produce a magnetic field. air blower for fishAccording to the working principle of magnets: same-poles repels and opposite-poles attracts.The maglev bearing is a magnetic induction coil bearing,we set the same-poles of magnet for the bearing coil and the rotating shaft,when the bearing coil is energized,the force of the magnet will float the shaft.The complete working principle of magnetic levitation blower will be like this:
1.when the maglev air blower is connecting with power,the maglev bearing controller will send out current signal,the current amplifier will amplify the current signal and send it to maglev bearing sensor,when the maglev bearing sensor receive the signal,it will send the current to maglev bearing,then the bearing magnet will generate the magnetic field,then the magnetic force will float the shaft.air blower machine
2.The VFD of the air blower is used for controling the motor running speed.When the motor is running,since the motor is connecting with the shaft,and shaft is connecting with impeller,then the shaft and impeller will run.When the impeller is running is high speed,it will generate a vacuum area,and the vacuum area will suck the surrounding air to the impeller,then the impeller will compress the air(at this time,the air will generate dynamic pressure) and discharge it to the outlet pipeline.
3.When the shaft is running in high speed,due to the gravity of the shaft,it will generate vibration and displacement,this will not good for the air blower,since the gap between shaft and maglev bearing is very small,displacement may result in shaft touching with the bearing.So it will require you need a very good software control system in maglev bearing controller.RAETTS maglev bearing controller can guarantee the shaft displacement error within 1um,which is much higher than the peers who can only do it within 10um.
4.In order to protect the maglev blower shaft from damage,we set a protection bearing which is to protect the shaft falling down in full running speed(when there is sudden power failure and the UPS power supply doesn’t work at the same time).
RAETTS is the first one who have the ability to produce the maglev turbo blower and air bearing centrifugal blower.We master the core technology,providing good quality air blower with very reasonable price,helping our customer to save more cost.air blower for fish

RAETTS standard type air bearing blowers,air blower machine
RAETTS miniature air foil bearing blower is designed for small sewage treatment plant,such as town STP,street WTP.These type of wastewater treatment plant has very small volume wastewater treatment capacity,only 500m3/day-1000m3/day.This type of small air bearing has the advantages such as compact size design,lower noise up to 65dB,easy installation and mainteance,small footprint.Many customers like to use air pressure blower to replace the heavy and loud noise roots blower.air blower machine
