真空泵真空泵vacuumpump利用机械、物理、化学、物理化学等方法对容器进行抽气,以获得和维持真空的装置。真空泵和其他设备(如真空容器、真空阀、真空测量仪表、连接管路等)组成真空系统,广泛应用于电子、冶金、化工、食品、机械、医药、航天等部门。真空泵真空系统示意图真空泵的种类很多。根据抽气机理可分为:①变容真空泵。利用泵腔工作容积的变化来抽气,如往复真空泵、旋片真空泵、余摆线真空泵、滑阀真空泵、罗茨真空泵和液环真空泵等。②动量传输真空泵。利用高速蒸气(汽)射流或高速旋转的转子来抽气,如油扩散泵、水蒸汽喷射泵、扩散喷射泵、涡轮分子泵等。③捕集真空泵。利用吸附和冷凝作用使气体分子永久或暂时贮存在泵内,如分子筛吸附泵、吸气剂离子泵、钛升华泵和低温泵等。另外,根据工作压力可分为低真空泵、中真空泵、高真空泵和超高真空泵4种;根据工作介质可分为水蒸气真空泵、油蒸气真空泵和水环泵等;根据在真空系统中所起的作用可分为主抽泵、增压泵、前置泵、粗抽泵和维持泵等。真空泵的主要性能参数有抽气速率(简称抽速)、极限压力(经相当长时间抽气后泵逐渐达到的最低压力)、工作压力范围(泵具有较大抽气能力时的压力范围)和何氏系数(泵喷嘴间面积上的实际抽速与该处按分子泻流计算的最大理论抽速比,由中国物理学家于20世纪30年代初在扩散泵的研究工作中首次提出的)。
