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

??? 骨架膠封 ??? 機械性密封隔絕 ??? 磁文丘里管密封構件

??應用/Application:

??? 大多數可可以用在進口重力作用脫氣、進口重力作用冶煉、進口重力作用干澀、進口重力作用熱清理等藝中。大型的泵型更可可以用在鋼水的進口重力作用清理、位置模仿、低體積風洞裝置設備等。 ??? 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. ??? 也可于石油化工、食品廠、生物制藥、電氣機 等工農業中的蒸發器、萃取低溫干燥等產量過程中 。 ??? 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:

??? 不僅有電腦運行時負載防護效果，另外還有提升 在較高出口處負擔(較低真空箱度)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). ??? 過濾管閥調節進氣口和res排氣口的負壓，使行駛愈來愈安全性可信度 ??? The adjustment of spillover valve for inlet and outlet pressure can enable safe and reliable operation. ??? 綜合運用骨架密封墊隔絕，密封墊隔絕特點好 ??? The use of frame sealing, good sealing performance. ??? 兩只運轉組件(水輪)間全是定間距，互不觸碰、摩擦力，故而不須得潤滑的油。 ??? There exists a gap between the two rotating components (impeller), without touch and frictions, so rubric oil is no need. ??? 根據搖動控制部件完成等勢面，有有效的靜態平衡性。 ??? As the rotating components completely symmetrical, there is good balance ??? 轉動結構件保障在四種的軸承上，以至于轉動好時機械高頻振動小，噪音污染不高 ??? 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(you)很大的抽(chou)速(su)，填補了雙級旋(xuan)片泵(beng)在(zai)這個壓力范圍的抽(chou)速(su)減弱缺陷，同時(shi)也(ye)可(ke)以(yi)作為增壓泵(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.
