低溫恒溫槽中壓縮機的工作原理是什么?

http://www.sewingmachine-review.com/Admin發布于 關鍵詞:

壓縮機作為低溫恒溫反應浴中的重要組成部分之一,其工作原理主要是根據物理學中壓力體積與溫度的關系,當氣體的質量一定時,壓力與體積的乘積是一個常數。因此,要實現單位質量的氣體的壓力升高一倍,就必須使其體積縮小一半。所有的低溫恒溫反應浴的壓縮機都是根據這個原理進遷氣體壓縮的。一般來說,實現氣體壓縮的物理方式有如下幾種: 相對靜止的氣體壓縮容積改變和流動氣體的通徑改變。   

1.相對靜止的氣體容積改變。如活賽式壓縮機、滾動轉子壓縮機、螺桿式壓縮機等。   

2.流動氣體的通徑改變,如渦旋式壓縮機、噴射式壓縮機。如全封閉壓縮機組制冷,制冷系統具有過熱、過電流多重保護裝置。
