三种密封方式可供选择/Three optional form of sealing:

  • 骨架密封

  • 机械密封

  • 磁流体密封组件

  应用/Application:

  • 普遍适用于真空脱气、真空冶炼、真空干燥、真空热处理等工艺中。大型泵型更适用于钢水的真空处理、空间模拟、低密度风洞装置等。

  • 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、医药、电力设备等工业中的蒸发、蒸馏干燥等生产过程。

  • 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.

  特点/Features:

  • 不仅有运行时过载保护作用，还有提高在较高入口压力(较低真空度)时的抽速

  • 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).

  • 溢流阀调整进气口和排气口的压力，使运行更加安全可靠

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

  • 运用骨架密封，密封性能好

  • The use of frame sealing, good sealing performance.

  • 两个转动部件(叶轮)间有一定间隙，互不接触、摩擦，因此不需要润滑油。

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

  • 由于转动部件完全对称，有很好的平衡性。

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

  • 转动部件支撑在四个轴承上，因此运转时机械振动小，噪音极低

  • The rotating components are supported by four bearings, so there is only small mechanical vibration and extreme low noise when running.

  • 在很大的压力范围内(1x10³Pa-1Pa)有很大的抽速，填补了双级旋片泵在这个压力范围的抽速减弱缺陷，同时也可以作为增压泵使用。

  • 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.
