分子泵的工作原理分子泵的抽气机理与机械泵靠泵腔容积变化进行抽气的机理不同，利用了动量传递原理，使分子定向流动而被排出泵外，从而达到抽气的目的。
分子泵在电机的带动下高速旋转，采用变频电源驱动电机，目的是得到较高的转速。
在分子流区域内，气体分子与高速转到的叶片表面碰撞，动量传递给气体分子，使部分气体分子在刚体表面的运动方向上，产生定向流动而被排出泵外，从而达到抽气的目的。
通常把用高速运动的刚体表面携带气体分子，并使其按一定方向运动的现象称为分子牵引现象，利用这一现象制成的真空泵称为牵引分子泵（盖德泵）。
牵引分子泵的优点是启动时间短，在分子流态下有很高的压缩比，能抽除各种气体和蒸气，特别适于抽除较重的气体。
但由于牵引分子泵抽速小，密封间隙太小，工作可靠性较差，易出机械故降，而且制造困难，实际上很少应用。
后来对牵引分子泵进行了改进，出现了涡轮分子泵，如图5-13所示。
涡轮分子泵内有多组相间动轮叶和定轮叶，每一个轮叶上有许多按一定角度斜置的叶片，如图5-14所示。
实际的涡轮分子泵都是由多级叶列串联组成，即按动片、定片、动片等依次交替排列，见图5-13。
动叶片转动时又类似于电风扇叶片的作用，能将气体从一侧抽到另一侧。
提高分子泵的转速，有利于提高分子泵的抽速。
由于叶片转速限制，如果气体分子运动速度较大，泵抽真空就比较困难。
可以看出，涡轮分子泵也是一种机械式真空泵，通过高速旋转的多级涡轮转子叶片和静止叶片的组合进行抽气的，在分子流区域内对被抽气体产生很高的压缩比，从而获得所需要的真空性能。
涡轮分子泵极限真空比扩散泵高，可达10-8pa。
正常工作时需要一定的前级真空度，其真空度高低视泵不同略有差异，一般在1-200pa之间，可采用机械泵作为前级泵，图5-15a就是由分子泵和机械泵组成的高真空机组。
由于涡轮分子泵的转速高，通常用中频电机带动，中频电源的频率在300-400HZ之间。
涡轮分子泵一般采用水冷方式。
复合式分子泵是涡轮分子泵与牵引分子泵的串联组合，如图5-15b所示，集两种泵的优点于一体，能在很宽的压力范围10-6-1pa内，具有较大的抽速和较高的压缩比，大大提高了泵的出口压力。
