描述

安捷伦瓦里安 VHS-400 扩散泵替换标准冷帽。
安捷伦瓦里安 PN K4823301。

这些 Agilent Varian VHS-400 扩散泵标准冷帽是可在客户现场安装的替换部件。冷帽有两种类型：标准型和扩展型。所使用的冷帽类型会影响诸如油回流和扩散泵的最终抽速等因素。例如，扩展冷帽是安装在 VHS-400 泵内代替标准冷帽的选件。它可以像光学密集挡板一样有效地阻止回流，但仍保留 80% 的泵速。残余回流非常低，以至于无法通过美国真空协会的标准收集方法进行测量。有关冷帽的位置，请参阅下面所示的分解图和零件插图中的第 1 项。有关冷帽的拆卸安装程序，请参阅下面 PDF 说明手册的第 41 页。这些标准冷帽是 OEM 原装 Agilent Varian 替换零件，零件号为 K4823301。
