摘要
罗茨真空泵机组因配用前级泵不同和所处工作压力范围的差异 ,相应其抽气速率变化较大 ,设计中应根据具体工况条件及真空系统使用要求 。
Pumping speed of roots pump changes a lot due to different backing pump and different range of working pressure. Concret conditions and requirements of vacuum system are taken into account to realize adaptability and economization of the roots pump unit.
