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

??? 骨架密封墊 ??? 機戒封密 ??? 磁氣固兩相流隔絕應用程序

??應用/Application:

??? 普通主要代替于渦流環境脫氣、渦流環境冶煉、渦流環境非常干燥、渦流環境熱加工等加工中。大形泵型更主要代替于鋼水的渦流環境加工、辦公空間模似、低體積密度風洞裝置設備等。 ??? 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. ??? 也可作于化工機械、飲食、生物制藥、供電局機 等工業中的汽化、減壓蒸餾干等生育的過程。 ??? 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:

??? 不僅有行駛時超負荷護理幫助，還是有升高在較高入口處壓強(較低抽真空度)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). ??? 溢出閥調節進氣口和進氣口的工作壓力，使電腦運行十分健康安全靠譜 ??? The adjustment of spillover valve for inlet and outlet pressure can enable safe and reliable operation. ??? 通過骨架封密隔絕，封密隔絕機械性能好 ??? The use of frame sealing, good sealing performance. ??? 3個高速旋轉主件(風輪)間一斜定時候，互不接觸性、磨擦，這樣不要潤滑液油。 ??? There exists a gap between the two rotating components (impeller), without touch and frictions, so rubric oil is no need. ??? 在運轉主件是完全中心對稱，有更好的動平衡性。 ??? As the rotating components completely symmetrical, there is good balance ??? 推動部位撐起、在四位軸承套上，為此機器運行時應械共振小，噪音分貝很低 ??? 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)有很大的(de)(de)抽(chou)速(su)，填(tian)補(bu)了雙級旋片泵(beng)在這(zhe)個壓力范圍的(de)(de)抽(chou)速(su)減弱缺陷，同時也(ye)可以作為增壓泵(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.
