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

??? 骨架密封墊 ??? 機械裝備隔絕 ??? 磁氣體封密控件

??應用/Application:

??? 多見的采適適用抽蒸空系統脫氣、抽蒸空系統冶煉、抽蒸空系統干熱、抽蒸空系統熱補救等加工工藝中。中大型泵型更采適適用鋼水的抽蒸空系統補救、前景模擬機、低高密度風洞系統等。 ??? 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. ??? 也常用于有機化工、食材、藥業、電力工程設配等工業園中的汽化、萃取常溫、干燥等產出的時候。 ??? 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自我保護的功效，另外還有提高自己在較高出口重壓(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). ??? 魚缸底濾閥調控進氣口和進氣口的壓，使執行變得更加很安全穩定 ??? The adjustment of spillover valve for inlet and outlet pressure can enable safe and reliable operation. ??? 使用骨架封嚴圈，封嚴圈效能好 ??? The use of frame sealing, good sealing performance. ??? 5個轉安全裝置(風扇葉片)間很多定空隙，互不接受、滾動摩擦，這樣不要求軸承空壓機油油。 ??? There exists a gap between the two rotating components (impeller), without touch and frictions, so rubric oil is no need. ??? 因為勻速轉動元器件壓根對稱性，有特別好的平衡量性。 ??? As the rotating components completely symmetrical, there is good balance ??? 甩動零件支撐體系在以下滾柱軸承上，從而日常運轉契機械振蕩小，噪音污染過低 ??? 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)抽速，填補了雙級旋片泵(beng)在(zai)這個壓(ya)力范圍的(de)抽速減弱缺(que)陷(xian)，同時也可以作為增壓(ya)泵(beng)使用(yong)。

??? 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.
