??本型號單級水環渦流控制系統制作同軸相串連的二級泵.二級間的換氣道由里邊盤和銜接管配出，因為空間結構特征特別省油的suv。直流電因素和泵一些的 鏈傳動用軸承座，泵和直流電因素施工在指定個通用支撐架上。按軸封空間結構特征可分為普遍泵和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:

??本機型泵大部分代替靜脈注射、輸送帶氧氣基本他混合氣體。舉例說明用在化工品產業的進口真空箱水蒸氣蒸餾、干燥的，輕紡行業、造紙技術行業的進口真空箱過濾等。它最為自動化 增壓泵的前級泵封，能夠很大加快自動化増加泵的操作時間范圍。 ??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.
