What is the core technology of air suspension blower? 

 Jiangsu Weigu Fluid - industry well-known blower series product provider.

 Air suspension blower mainly includes impeller, air suspension bearing, frequency converter, high speed permanent magnet motor and its structure control system. The motor spindle is coaxial with the fan impeller, and the high-speed rotor system is directly supported by the air suspension bearing. Its main core technology is air suspension bearing technology, high speed permanent magnet synchronous motor and its control technology. The air suspension bearing takes air as the working medium, elastic flat foil as the supporting surface, and elastic wave foil as the supporting member. Initially, the impeller rotor is in contact with the bearing, but when the rotor enters a high-speed rotation state, due to the viscosity of the air and the action of the wedge, there will be a dynamic pressure effect between the planes. Elastic deformation of flat foil and corrugated foil occurs on the surface of foil and rotor, the flat foil is pushed away, and then the rotor is suspended. The uneven circumferential air pressure makes the foil bearing capable of bearing loads. Or more simply, during the rotor's high-speed rotation, a high-pressure gas film is formed between the rotor and the foil, thereby lifting the rotor. It can be seen from the above that although there is no friction in the impeller rotor after the normal operation of the air suspension blower, this does not mean that the equipment is completely frictionless during the entire process. In the start and stop stage of the foil bearing, when the speed is lower than the critical speed, the dynamic pressure effect is not enough to fix the rotor. At this time, there will still be contact friction between the inner surface of the bearing and the rotor. This period of time is short, but there is still a flat foil. The wear problem of the film can shorten the service life, so frequent start-stop operations must be minimized when using air suspension blowers. At the same time, in order to improve the service life of dynamic pressure bearings, high-quality lubricating coatings must also be applied to the bearing surface.
