??三種密封方式可供選擇/Three optional form of sealing:

??? 骨架良好的密封性 ??? 機械裝備密閉 ??? 磁文丘里管密封蓋元件

??應用/Application:

??? 都可廣泛采用渦流脫氣、渦流冶煉、渦流干澀、渦流熱正確工作等方法中。大型的泵型更可廣泛采用鋼水的渦流正確工作、發展空間模擬系統、低黏度風洞裝備等。 ??? Widely applied to the process such as vacuum degassing, vacuum metallurgy, vacuum drying and vacuum heat treatment.Large-scale pump is more suitable for the applications such as steel vacuum processing, spatial modeling and low-density wind tunnel device etc. ??? 也都可以于化工新材料、美食、醫藥業、電力的設備的設備等企業中的蒸發器、水蒸氣蒸餾干躁等生產加工的過程。 ??? It can also be applied to the manufacturing process of evaporation, distillation and drying in the industries such as chemical, food, medicine, electric power equipment.

??特點/Features:

??? 不僅有使用時負載護理用，更有提高自己在較高填報志愿系統氣壓(較低真空體度)時的抽速 ??? It is not only has the effect of run-time overload protection, but also can improve the pump rate under higher inlet pressure (lower vacuum). ??? 進水口閥改變進氣口和排氣口口的壓為，使運作進一步健康可以信賴的 ??? The adjustment of spillover valve for inlet and outlet pressure can enable safe and reliable operation. ??? 運作骨架密封圈帶，密封圈帶性能參數好 ??? The use of frame sealing, good sealing performance. ??? 二個翻轉組件(離心葉輪)間一定孔徑，互不碰到、滾動摩擦，往往不必須 進行潤滑處理油。 ??? There exists a gap between the two rotating components (impeller), without touch and frictions, so rubric oil is no need. ??? 會因為螺桿旋轉元件完全性對應點，有很棒的平橫性。 ??? As the rotating components completely symmetrical, there is good balance ??? 推動機械部件承受在3個軸承套上，往往正常運轉前應械激振小，躁音超低 ??? The rotating components are supported by four bearings, so there is only small mechanical vibration and extreme low noise when running.

??? 在很大的壓力范圍內(1x10³Pa-1Pa)有很大(da)的(de)抽速(su)，填補了雙級(ji)旋片泵(beng)(beng)在(zai)這個壓力(li)范圍的(de)抽速(su)減(jian)弱(ruo)缺陷，同時也可以作為增壓泵(beng)(beng)使用。

??? The pump rate is very high under huge pressure range (1><10³Pa-1Pa). The defect of pump rate reduction for Bipolar Rotary-vane Pumps under this pressure range is filled, meanwhile it can also be used as booster pumm.
