离心泵轴向密封的改进

Improvements of Axial Seals Used in Centrifugal Pump

本文根据离心泵的轴向密封实际,提出了2种结构的改进:1.将泵的软填料径向密封改为端面密封;2.将软填料密封盒与机械密封盒加工成统一标准化的装置,使两种密封装置按需选择使用或互换使用。

There are two improvements in axial seals used in the centrifugalpumps:1)Radial seals made by soft packing are changed into face seal;2)Seal-ing boxes for soft packing and mechanical seals are made into a standard devices,so they may be exchangeable (or selective).
