??本型號雙級水環真空系統做成同軸相串聯的兩級泵.兩級之間的通氣道由中間盤和連接管配成，因此結構比較緊湊。電動機和泵部分的 傳動用聯軸器，泵和電動機安裝在同一個公共底座上。按軸封結構分為普通泵和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 divided into ordinary pump and model-A pump.

??應用/Application:

??本型號泵主要用來抽吸、輸送空氣及其他氣體。例如用在化工行業的真空蒸餾、干燥，輕紡工業、造紙工業的真空脫水等。它作為機械 增壓泵的前級泵封，可以大大提高機械増加泵的使用范圍。

??The pump of this model is mainly used to extract, suet and transfer aire and other gases.For example, vacuum evaporation and drying in chemical industry, vacuum dehydration in textile and paper industry etc.lt can be used as prepump sealing for Roots blower pump and the range of use for Roots blower pump can be greatly improved.
