ZJ/ZJB型罗茨真空泵
Model ZJ/ZJB Roots Vacuum Pump:

 

三种密封方式可供选择:
Three optional form of sealing:
●骨架密封
Skeleton sealing
●机械密封
Mechanical sealing
●磁流体密封组件
Magnetic liquid sealing components

 

应用:Application:
广泛适用于真空脱气、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(1×103Pa-1Pa)有很大的抽速,填补了双极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.
