                  Large contrast between air suspension centrifuge and magnetic suspension blower



                  Air Suspension Centrifugal blower is a kind of single-stage high-speed Centrifugal blower


                  It uses three core high-end Technologies: ultra-high-speed direct-coupled Motor, air suspension bearing and high-precision single-stage Centrifugal impeller With no gear speed-up device, no mechanical contact, no lubrication system, variable frequency speed regulation air flow, low noise, no vibration and low maintenance costs, etc. Different from the ordinary fan is the use of non-contact bearing air suspension bearings.



                  The magnetic suspension centrifugal blower is one kind of single-stage high-speed Centrifugal blower


                  At its heart are magnetic bearing and permanent magnet motor technology. The key components are magnetic bearings, which use the principle of constant magnetic conduction to realize the high-speed stable and frictionless operation of the rotating shaft by electromagnetic force, and use the position sensor, power amplifier and Pi Arithmetic The active control ability can effectively restrain the unbalance vibration of the rotating shaft, and there are complete and strict protection measures for power cut.



                  Common Technical Characteristics of air suspension fan and magnetic suspension fan


                  01、 Energy efficient


                  Adopting suspension bearing, no contact loss and mechanical loss, high speed stepless variable speed regulation is realized, making the Fan operating efficiency as high as 95% .


                  02、ow noise, small size, easy installation


                  All components (high-speed Motor, frequency converter, suspension bearing) are integrated on the common base without special fixed foundation, small size, light weight, easy to install and operate, low noise and no vibration in operation, noise level < 80dB.

                  03、High System Integration


                  Blower itself has integrated local control and frequency conversion system in one, do not need to set up a separate frequency conversion cabinet and Operation Cabinet. Through the control panel of the fan itself, various functions can be set and the parameters of fluid temperature, motor rotation, air pressure, air volume, power consumption can be queried. High-efficiency filter, cooling system, automatic anti-surge system, power failure and fault protection system are installed in the Fan Cabinet, real-time touch screen, for the operation of workers to facilitate and reduce the occurrence of operational accidents.


                  04、easy to use, easy to maintain, low cost, long life


                  Blower Motor is directly connected with impeller, no gear speed increasing device, no mechanical contact, no lubricating oil system, no wear and energy loss, low maintenance cost, power transfer efficiency of more than 95% . Impeller selection of high-strength aluminum, Ti material, with excellent wear-resistant, anti-deformation capacity, service life of more than 30 years. Frequency converter is used to regulate the air flow, which is more energy-saving than the throttle valve and has a wide range of air flow regulation, usually 50% ~ 100% .


                  05、Cooling efficiency


                  The cooling system adopts the combination of Air Cooling and Water Cooling, which can effectively protect the motor and realize the start and stop of the fan at any time.


                  06、遠Remote control


                  it Adopts PLC + GPRS. Can Be controlled by the central control room, if the fan failure, you can also implement remote maintenance debugging.


                  The advantages and disadvantages of air-levitation fan and magnetic-levitation blower

                  1

                  Air Suspension Fan because of the use of external dynamic pressure air, in the low speed, the spindle dry friction, but this friction on the spindle caused little wear.

                  2

                  Magnetic Levitation fans need to supply magnetic power to the magnetic bearing, consume more power than levitation, and need a backup power supply and a backup bearing to avoid sudden power failure to the fan damage Generally speaking, there is a limit to the number of times a spare bearing can be used.

                  3

                  The structure of the magnetic bearing and controller is more complex and the failure rate is higher than that of the air bearing

                  4

                  Air Suspension Fan technology is relatively developed in South Korea at present. The main ones entering the Chinese market are South Korea Hi-Turbine Sea Tobin Neuros (Neuros) and several other companies. All of the above-mentioned companies have repair sites in China; among them, Hi-Turbine technology is the strongest Has Developed 4.0 bar air suspension centrifugal compressor, magnetic levitation blower has not broken through 1.2 bar above pressure, price, air suspension fan than magnetic levitation fan to low.
