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

??? 骨架密封

??? 機(jī)械密封

??? 磁流體密封組件

??應(yīng)用/Application:

??? 普遍適用于真空脫氣、真空冶煉、真空干燥、真空熱處理等工藝中。大型泵型更適用于鋼水的真空處理、空間模擬、低密度風(fēng)洞裝置等。

??? 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.

??? 也可用于化工、食品、醫(yī)藥、電力設(shè)備等工業(yè)中的蒸發(fā)、蒸餾干燥等生產(chǎn)過(guò)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(diǎn)/Features:

??? 不僅有運(yùn)行時(shí)過(guò)載保護(hù)作用，還有提高在較高入口壓力(較低真空度)時(shí)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).

??? 溢流閥調(diào)整進(jìn)氣口和排氣口的壓力，使運(yùn)行更加安全可靠

??? The adjustment of spillover valve for inlet and outlet pressure can enable safe and reliable operation.

??? 運(yùn)用骨架密封，密封性能好

??? The use of frame sealing, good sealing performance.

??? 兩個(gè)轉(zhuǎn)動(dòng)部件(葉輪)間有一定間隙，互不接觸、摩擦，因此不需要潤(rùn)滑油。

??? There exists a gap between the two rotating components (impeller), without touch and frictions, so rubric oil is no need.

??? 由于轉(zhuǎn)動(dòng)部件完全對(duì)稱，有很好的平衡性。

??? As the rotating components completely symmetrical, there is good balance

??? 轉(zhuǎn)動(dòng)部件支撐在四個(gè)軸承上，因此運(yùn)轉(zhuǎn)時(shí)機(jī)械振動(dòng)小，噪音極低

??? 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(nèi)(1x10³Pa-1Pa)有很大的抽速，填補(bǔ)了雙級(jí)旋片泵在這個(gè)壓力范圍的抽速減弱缺陷，同時(shí)也可以作為增壓泵使用。

??? 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.
