Maglev centrifugal blowers have been successfully used instead of Roots blowers. After operation, the effect of energy saving and consumption reduction is remarkable. The
magnetic suspension blower is a centrifugal blower. The active magnetic suspension bearing system is used to carry out non-contact and wear-free suspension support for the internal rotating magnetic suspension bearing through controllable electromagnetic force. When starting, the magnetic suspension bearing is first suspended and then rotated. The magnetic suspension bearing is directly connected with the impeller and has zero transmission loss, so as to achieve the effects of successfully conveying gas without wear, low noise, no lubrication, energy saving and high efficiency, fan operating efficiency can reach 84.5% . At the same time, the magnetic suspension blower has excellent structural performance, the magnetic suspension bearing has no mechanical friction, and the high-speed motor and three-dimensional flow impeller are used to ensure that the fan can stably increase a large amount of gas under the condition of high-speed rotation. Compared with Roots blower, energy saving 20%-30% , noise is as low as 80 decibels.
