2S型双级水环真空泵

Model 2S Two-stage Water-Ring Vacuum Pump

本型号双级水环真空系统做成同轴相串联的两级泵，两级之间的通气道由中间盘和连接管配成，因此结构比较紧漆。电动机和泵部分的传动用联轴器，泵和电动机安装在同一个公共底座上。按轴封结构分为普通泵和A型泵。

This model of two-stage water-ring vacuum pump system is coaxial with two-stage pumps. The ventilation path between the two stages is consist of the middle plate and connecting pipe，so the structure is very compact. The parts of electronic motor and pump is driven by coupling. The pump and electronic motor are installed on the same common pedestal. According to the structure of extraction and seal，it is categorized as ordinary pump and model-A pump.

应用/Application

本型号泵主要用来抽吸、输送空气及其他气体。例如用在化工行业的真空蒸馏、干燥，轻纺工业、造纸工业的真空脱水等。它作为机械增压系的前级泵封，可以大大提高机械增加泵的使用范围。

The pump of this model is mainly used for extracting and transferring air and other gases. For example，vacuum evaporation and drying in chemical industry, vacuum dehydration in textile and paper industry etc. It can be used as pre-pump sealing for Roots blower pump and the range of use for Roots blower pump can be greatly improved.
