摘要
本文对水压式主轴密封进行了数学分析,建立了该密封达到良好运行状态必须满足的条件。同时指出了这种密封在低比转速混流式水轮机上使用的局限性。
In this paper, the water-pressed main shaft seal is mathematically analyzed. Some necessary conditions to attain good operational state of this seal are built up. Meanwhile, the limitation of the seal used in low specific speed Francis turbines is pointed out.
