真空泵的原理

3.1 GAISHU

3.1.1 ZHENKONGDEHUODEFANGFA

人们通常把能够从密闭容器中排出气体或使容器中的气体分子数目不断减少的设备称为真空获得设备或真空泵。目前在真空技术中,采用各种不同的方法,已经能够获得和测量从大气压力105Pa到10-13Pa,宽达18个数量级的压力范围。显然,只用一种真空泵,获得这样宽的低压空间的气体状态,是十分困难的。

在真空获得技术中,目前用以获得真空的技术方法有两种,一种是通过某此机构的运动把气体直接从密闭容器中排出;另一种是通过物理、化学等方法将气体分子吸附或冷凝在低温表面上。利用这两种方法所制造的各种真空泵种类较多,分类方法各异,但是,优越常用的方法还是按泵的工作原理或其结构特点加以分类。这一点,我们将在下一节中介绍。

a)旋片式真空泵皇冠即时比分:转子以一定的偏心距装在泵壳内并与泵壳内表面的固定面靠近,在转子槽内装有两个(或两个以上)旋片,当转子旋转时旋片能沿其径向槽往复滑动且与泵壳内壁始终接触,此旋片随转子一起旋转,可将泵腔分成几个可变容积。

b)滑阀式真空泵皇冠即时比分:在偏心转子外部装有一个滑阀,转子旋转带动滑阀沿泵壳内壁滑动和滚动,滑阀上部的滑阀杆能在可摆动的滑阀导轨中滑动,而把泵腔分成两个可变容积。
