由于罗茨泵是一种无内压缩的真空泵，通常压缩比很低，故高、中真空泵需要前级泵。
As the Roots pump is a non-vacuum inside the compression, the compression ratio is usually very low, so high, medium and vacuum pumps need to pump before.
本机组采用罗茨泵作为主泵，以旋片式真空泵作为前级泵。
The set takes Roots pump as its main pump and spinning vacuum pump as pre-stage pump.
在涡轮分子泵的前级侧充气，能强制使碳氢化合物立刻通过涡轮分子泵流入真空室。
