技術說明

Dolphin LR is a series of single-stage liquid ring vacuum pumps. An eccentrically mounted impeller rotates in a housing partially filled with operating fluid. The impeller blades dip into the fluid, and the centrifugal force exerted by their rotation forms a so-called liquid ring within the housing.


The pumped medium is transported in the spaces between the blades and the liquid ring. The eccentric rotation of the impeller alters the volume of these spaces, causing gas to be drawn in, compressed and expelled.

  • 用於化工與製藥行業的真空技術
    為化工與製藥行業應用選擇適合的真空技術往往並非易事。首先,真空系統必須在工作壓力下提供所需幫浦速度,確保所需抽真空時間。其次,它不能對工藝氣體敏感,在用於CIP(在位清洗)清洗和氣體回收時必須滿足所有要求。此外,在確定要使用哪種真空技術時,穩定性和經濟效率也起著重要作用。 在本文中,我們將講述化工與製藥加工技術中最常用的三種真空技術。 水封式真空幫浦, 乾式螺桿真空幫浦, 油潤滑迴轉葉片真空幫浦
