The invention discloses a magnetic energy saving fan, which aims to provide a fan for reducing friction resistance, energy saving and durable, the technical scheme is characterized in that the position before and after the fan shaft length respectively in the periphery with the rotation of the shaft moving magnet and the outer magnet for static and static. And in the spindle and the spindle is placed or attached to the moving magnet before and in or after the static magnet, magnet moving and static magnets repel each other, thus achieving mutually sticking in operation. The two directions of the middle and rear sections of the vertical fan main shaft and the position of the magnet and motor are open, and the upper and lower sides are closed. The upper and lower part of the closed type is a double-layer structure which is not attached to each other, that is, there is a gap. If necessary, water is injected into the voids of the double-layer structure, so as to achieve the purpose of cooling.

一种磁悬浮节能引风机
本专利技术涉及为促使气体流动的一种机械设备,更具体更确切地讲是适用于将窑炉中的废气引出的一种引风机。
技术介绍
当今即现有技术中的各种风机由于少不了用于定位和抵销反压力的各种轴承,含防止前后左右偏位用的径向轴承和阻止后退用的止推轴承,因而在运转中存在一定的磨擦阻力,由此导致耗能较多,以烧砖窑炉上的引风机为例,其结构与做功原理如图1所示:圆柱形机壳3安装在基座1上,由多片叶片5(图中仅示出左右各一片)组成的叶轮5套装在主轴6的上端外围,中心主轴的中间段相互隔开一定距离的上下分别安装有轴承和轴承座4和7用于定位,其中4为单个径向轴承,7为径向轴承和止推轴承各一个分上下贴合,电机10安装在机壳外、以防高温为害,借助三角带9将电机上的传动轮11和风机主轴上的传动轮8牵连套合,机架12上的电动机在运转中带动风机高速旋转,在旋转中将高温废气从下边吸入、往上边排出,为防止高温烟气危害风机轴承和皮带、而在其下位与外缘加装有防护罩2将风机与热烟气隔离,并在叶轮背面下边的防护罩上留有少量空隙、利用运转中所形成的负压从机壳外吸进一部分冷空气用于降溫,高温废气顺大箭 ...
