一般罗茨风机都是不允许反转的(因为进气口跟排气口的间隙设置不一样),所以罗茨风机都需要在排气端设置单向阀。也就是允许风从罗茨风机输入到管道系统,防止罗茨鼓风机突然停机,罗茨风机而系统的气体收到系统压力的作用,回流冲击罗茨风机造成罗茨风机反转,损坏罗茨鼓风机另外,几台罗茨鼓风机并联运行的时候,假设其中一台不工作,那么单向阀也可以防止排气端的气体通过这台没有使用的罗茨鼓风机,造成其反转损坏。
Generally, the roots blower is not allowed to reverse (because the gap setting between the air inlet and the exhaust port is different), so the roots blower needs to set a check valve at the exhaust end. In other words, it allows the air to be input from roots blower to the pipeline system to prevent the roots blower from sudden shutdown. The roots blower and the gas in the system receives the effect of system pressure, and the backflow impacts the roots blower, causing the roots blower to reverse and damage the roots blower. In addition, when several roots blowers operate in parallel, it is assumed that one of them does not work, Then, the check valve can also prevent the gas at the exhaust end from passing through the unused roots blower, resulting in reverse damage.
总而言之,就是保护罗茨风机不反转.按结构形式分:立式型罗茨风机两转子中心线在同一垂直水平面内,气流水平进,水平出;卧式型罗茨风机两转子中心线在同一水平面内,气流垂直进,垂直出。所说的风叶相碰。
In short, it is to protect the roots blower from reverse rotation. According to the structural form, the center lines of the two rotors of the vertical roots blower are in the same vertical horizontal plane, and the air flow enters and exits horizontally; The center lines of two rotors of horizontal roots blower are in the same horizontal plane, and the air flow enters and exits vertically. The wind leaves collide.
绝大部分是轴承间隙变大引起的,如果更换同步齿轮不行,建议使用质量较好的轴承,不用进口的最起码也得用瓦轴或洛轴的高速轴承,罗茨风机齿轮的磨损可以根据齿轮咬合间隙判断,如果齿轮磨损超限,可以将两个同步齿轮翻面处理,这样齿轮就可以延长一倍使用寿命,调整两风叶间隙时一定要用塞尺沿风叶长度测定4个点以上,罗茨鼓风机保证整个长度上的间隙均匀、一致。
Most of them are caused by the larger bearing clearance. If it is not possible to replace the synchronous gear, it is recommended to use bearings with better quality. If it is not necessary to import, at least the high-speed bearings of bearing bush or Luo shaft should be used. The wear of Roots blower gear can be judged according to the gear engagement clearance. If the gear wear exceeds the limit, the two synchronous gears can be turned over, In this way, the service life of the gear can be doubled. When adjusting the clearance between the two blades, be sure to use a feeler gauge to measure more than 4 points along the length of the blades. Roots blower ensures that the clearance on the whole length is uniform and consistent.
