罗茨风机是两个相同转子形成的一种压缩机械,转子的轴线互相平行,转子中的叶轮与叶轮、叶轮与机壳、叶轮与墙板留有微小的间隙,避免相互接触,构成进气腔与排气腔互相隔绝,借助两转子反向旋转,将体内气体由进气腔送至排气腔,达到鼓风的作用。由于叶轮之间、叶轮与机壳、叶轮与墙板均存在很小的间隙,所以运行时不需要往气缸内注润滑油,也不需要油气分离器辅助设备。由于不存在转子之间的机械摩擦,因此机械效率高,整体发热少,使用寿命长等优点。罗茨风机是比较精的设备,平时保养要注意入口过滤器的清扫和更换,室内空气的干净与通畅,润滑要保证。

Roots blower is a kind of compression machine formed by two identical rotors. The axes of the rotors are parallel to each other. There is a small gap between the impeller and the impeller, between the impeller and the casing, and between the impeller and the wallboard in the rotor to avoid mutual contact. The intake chamber and the exhaust chamber are isolated from each other. With the help of the reverse rotation of the two rotors, the gas in the body is sent from the intake chamber to the exhaust chamber to achieve the role of blowing. Since there is a small gap between the impellers, between the impellers and the casing, between the impellers and the wallboard, there is no need to inject lubricating oil into the cylinder or auxiliary equipment of the oil-gas separator during operation. Since there is no mechanical friction between rotors, it has the advantages of high mechanical efficiency, less overall heating and long service life. Roots blower is a relatively sophisticated equipment. During normal maintenance, attention should be paid to the cleaning and replacement of inlet filter, the cleanness and smoothness of indoor air, and the lubrication should be guaranteed.

罗茨风机是容积式风机。其风量随转速的增减而增减、风压与电流相关。即流量受背压影响小。返料阀正是利用了罗茨风机的这个特点实现了松动风的定流量调节。在运行时注意风机的排风压力应在标牌数值以下,以免损坏其内部的压力部件。

Roots blower is a positive displacement blower. The air volume increases or decreases with the increase or decrease of speed, and the air pressure is related to the current. That is, the flow is less affected by back pressure. The return valve makes use of the characteristics of Roots blower to realize the constant flow regulation of loose air. During operation, pay attention that the exhaust pressure of the fan shall be below the value on the label to avoid damaging its internal pressure parts.
