我们都知道罗茨泵有两个相同的转子以等速相反方向旋转;转子之间、转子与定子之间不接触,转速高;体积小;抽速大;耗费功率小;启动快;在1—10-2托范围内具有稳定的大抽速;并可以抽除大量可凝性气体。由于这些特性,罗茨泵通常在真空系统中充当增压泵。但是近些年它经过不断革新和 We all know that Roots pumps have two identical rotors rotating at equal speeds in opposite directions; no contact between the rotors, the rotor and the stator, high speed; small size; large pumping speed; low power consumption; fast start-up; -10-2 Torr within the framework of a stable pumping speed; and can extract a large amount of condensable gas. Due to these characteristics, Roots pumps usually act as a booster pump in a vacuum system. But in recent years it has undergone constant innovation
