羅茨風機工作原理:
Roots blower works:
三葉型兩葉輪在機體內通過同步齒輪的作用，呈反方向嚙合旋轉。葉輪相互之間、葉輪與殼體、墻板之間均有適當的工作間隙，它們構成進氣腔與排氣腔相對隔絕。利用葉輪旋轉，將機體內的氣體由進氣腔推送至排氣腔后排出機體，達到鼓風的目的。
Clover two impeller with a synchronous gear function in the body in the opposite direction of rotation, gear. Between the impeller, the impeller and the casing, between the wallboard appropriate working gap, they form an air inlet chamber and an exhaust chamber relative isolation. The impeller rotation, the gas discharged from the body by the inlet cavity push to the exhaust cavity body, achieve the purpose of blast.
