羅茨風機是兩個相同轉子形成的一種壓縮機械,轉子的軸線互相平行,轉子中的葉輪與葉輪、葉輪與機殼、葉輪與墻板留有微小的間隙,避免相互接觸,構成進氣腔與排氣腔互相隔絕,借助兩轉子反向旋轉,將體內氣體由進氣腔送至排氣腔,達到鼓風的作用。由于葉輪之間、葉輪與機殼、葉輪與墻板均存在很小的間隙,所以運行時不需要往氣缸內注潤滑油,也不需要油氣分離器輔助設備。由于不存在轉子之間的機械摩擦,因此機械效率高,整體發熱少,使用壽命長等優點。羅茨風機是比較精的設備,平時保養要注意入口過濾器的清掃和更換,室內空氣的干凈與通暢,潤滑要保證。

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.

羅茨風機是容積式風機。其風量隨轉速的增減而增減、風壓與電流相關。即流量受背壓影響小。返料閥正是利用了羅茨風機的這個特點實現了松動風的定流量調節。在運行時注意風機的排風壓力應在標牌數值以下,以免損壞其內部的壓力部件。

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.
