循環水真空泵的使用與選型分析

Admin發布于 關鍵詞:循環水真空泵 循環水式真空泵 循環水式多用真空泵

實驗室里比較常見的抽真空的設備——循環水式真空泵在選型時,有部分用戶仍存在疑問:什么情況下才選用一級泵更合適?循環水真空泵工作時,原則上建議在高效環境中運行,比如在臨界點或臨界區域內運行。盡量避免多用真空泵在高壓高真空(臨界最大值)區域內運行。否則工作效率極低且不穩定,振動噪聲比較大。對于真空度高的還會出現汽蝕現象,有可能會導致零部件損壞,嚴重的情況會導致循環水式多用真空泵無法運行。

常規情況下,要求不高時,可以優先考慮一級泵,不僅高效節能且故障率低,具有無故障工作周期長的優點。如果要求環境比較苛刻,一級無法滿足的情況下才選用二級泵。
