應用：Application:

    廣泛適用于真空脫氣、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、低密度風洞裝置等。也可用于化工、食品、醫藥、電力設備等工業中的蒸發、蒸餾干燥等生產過程。
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.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:

■  不僅有運行時過載保護作用，還有提高在較高入口壓力（較低真空度）時的抽速
It is not only has the effect of runtime overload protection, but also can improve the pump rate under higher inlet pressure (lower vacuum).

■  溢流閥調整進氣口和排氣口的壓力，使運行更加安全可靠
The adjustment of spillover valve for inlet and outlet pressure can enable safe and reliable operation.

■  運用骨架密封，密封性能好
The use of frame sealing, good sealing performance.

■  兩個轉動部件（葉輪）間有一定間隙，互不接觸、摩擦，因此不需要潤滑油。
There exists a gamp between the two rotating components (impeller), without touch and frictions, so lubric oil is no need.

■  由于轉動部件完全對稱，有很好的平衡性。
As the rotating components completely symmetrical, there is good balance

■  轉動部件支撐在四個軸承上，因此運轉時機械振動小，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（1×103Pa-1Pa）有很大的抽速，填補了雙極旋片泵在這個壓力范圍的抽速減弱缺陷，同時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.
