一种用于薄壁平面工件固定的真空吸附装置

, 2011
本实用新型公开了一种用于薄壁平面工件固定的真空吸附装置，包括真空吸附板和密封盖板。真空吸附板的上表面设有贯穿真空吸附板的n个吸气孔，下表面开设有m条互不连通的真空凹槽，每条真空凹槽既与若干吸气孔相连通，也与抽真空系统的吸气管相连通。每条真空凹槽周边均开设有互不连通的环绕真空凹槽的环形密封槽，内置密封材料，与密封盖板一起，将真空吸附板的上表面形成了m个互不连通的真空吸附区域。结合吸气孔孔塞的使用，可以解决真空吸附装置工作过程中个别吸气孔出现突发密封问题所导致工件吸附失效问题 ...

真空开关对触头材料含气量要求的初步探讨

Gaoya dianqi, 1977
真空开关开断过程中,触头会有所烧损,触头材料中所含的气体分子将放出,这些放出的气体对开断中的灭弧过程及开断后灭弧室的真空度会产生什么影响呢?这是一个值得深入研宄探讨的问题。本文作者着重对开断后灭弧室真空度会发生怎样的变化这一问题作了探讨性分析。作者认为,在触头烧损放出气体的同时,触头烧损形成的蒸汽流将射向屏蔽罩,附着在屏蔽罩上形成金属蒸汽沉积层,这个金属蒸汽沉积层在形成过程中将吸收一大批气体分子,从而,开断后灭弧室真空度的变化,不仅受触头烧损放气的影响,也同样受屏蔽罩吸气的影响。据此概念 ...
