乙苯循环泵机械密封的改进

Improving of Mechanical Seal of EB Circulation Pump

乙苯泵的机械密封由双端面外冲洗型结构改为单端面自冲洗型结构并确认其端面比压值的合理性 。

The structure of double side and external washing of mechanical seal was changed into the one of single side and internal washing. We affirm the difference of pressure on side-face is rational and the problem that the washing liquid leak into medium is solved.
