油扩散泵

PBL 系列

PBL-02

アルバック

ULVAC的PBL型油扩散喷射泵、是在中真空领域可以提高排气速度的扩散泵。有效对应异物混入,从发售开始一直畅销至今。

特点

  • 10-1Pa排气速度最大。
  • PBL-02~PBL-04型使用不锈钢作为主体(气缸)。 因此。出气少,容易获得高真空,并且耐腐蚀性优异。
  • 与水平喷射泵相比,操作范围向低压侧移动约一位数,但同口径的泵排气速度要大得多,并且排气速度特性也很好。 可在油回转真空泵,机械增压泵和油扩散泵的中间压力下使用,并且安装面积小。
  • 大型泵PBL-06~PBL-20管式加热器直接包含在液压流体中,因此热效率特别高。

*1 The ultimate pressure by an ionization gauge in the case of coolant temperature 20 degrees Ceisius.
*2 The backing pump chooses it for the maximum throughput of the diffusion ejector pump,but,in consideration of time of starting pressure,it is good to use a big backing pump.
*3 Please confirm other dimensions by CAD data placing in the ULVAC,Inc.website.
