原文:
真空泵(以后简称泵)是单级液环设备,主要用于抽输低于大气压的气体和蒸汽。装到轴上的叶轮偏心地安装在圆柱形泵体内,并可在其中转动(见图2.1a到2.1d),叶轮的转动使工作液在泵体内形成一转动的液环,液环在叶轮的两个叶片之间脉动,在吸气侧,液环逐渐远离叶轮轮毂,气体通过圆盘上的吸气口轴向进入泵内;在排气侧,液环又逐渐靠近叶轮轮毂,气体被压缩并通过圆盘上的排气口被轴向排出。提示:该泵适用于抽输干燥的或湿润的气体,而无危险情况发生,其前提为泵工作液和所抽输气体是无毒,无腐蚀性,非易燃易爆的,所供用于抽输易燃,易爆,有毒,腐蚀性介质的泵也能够满足用户的要求,但用户必须采取相应的安全预防措施。

译文:
Vacuum pump (hereinafter referred to as the pump) is a single-stage liquid ring device that is mainly used to pump gas and steam below atmospheric pressure. A impeller mounted on a shaft is eccentrically mounted in the cylindrical pump body and can rotate in it (see Figures 2.1a to 2.1d). The rotation of the impeller causes the working fluid to form a rotating liquid ring in the pump body, and the liquid ring pulsates between the two blades of the impeller, on the suction side, the liquid ring gradually moves away from the impeller hub, and the gas enters the pump axially through the suction port on the disc; On the exhaust side, the liquid ring gradually approaches the impeller hub, and the gas was compressed and axially exhausted through the exhaust port on the disc.
Note: The pump is suitable for pumping dry or humid gas without any dangerous situation. The premise is that the pump working fluid and the pumped gas are non-toxic, non-corrosive, non-flammable and non-explosive, and pumps that can pump flammable, explosive, toxic, corrosive media can also meet user requirements, but users must take appropriate safety precautions.
