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

??? 骨架密封 ??? 設備密封帶 ??? 磁粘性流體密封蓋應用程序

??應用/Application:

??? 多見的采主要不適應用于負壓脫氣、負壓冶煉、負壓非常干燥、負壓熱加工加工處理等技藝中。玄幻泵型更采主要不適應用于鋼水的負壓加工加工處理、空間模擬訓練、低高密度風洞安全裝置等。 ??? 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. ??? 也可于煤化工、面制品、醫療、供電設備等工業制造中的多效蒸發、水蒸氣蒸餾干燥處理等生育的過程 。 ??? 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:

??? 不僅有正常運作時超負荷自我保護做用，還是延長在較高入口通道負擔(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). ??? 溢出閥優化進氣口和res排氣口的負壓，使進行相對很穩定安全的 ??? The adjustment of spillover valve for inlet and outlet pressure can enable safe and reliable operation. ??? 利用骨架密封隔絕圈，密封隔絕圈穩定性好 ??? The use of frame sealing, good sealing performance. ??? 5個高速旋轉機件(風機葉輪)間有個定腐蝕痕跡，互不使用、靜摩擦力，對此不可以注油油。 ??? There exists a gap between the two rotating components (impeller), without touch and frictions, so rubric oil is no need. ??? 根據甩動組件幾乎等勢面，有更好的動平衡性。 ??? As the rotating components completely symmetrical, there is good balance ??? 旋轉機件支撐力在4個滾柱軸承上，由此旋轉時間械運動小，燥音超低 ??? 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(da)的抽速(su)，填(tian)補了雙級(ji)旋(xuan)片(pian)泵在(zai)這(zhe)個壓力范圍的抽速(su)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.
