水轮机密封材料的研制及其使用性能的考察

Development and Performance of Seal Materials for Water Turbine

作者为八盘峡水电站进口水轮机组研制了一种密封材料,它是用浸渍油改性酚醛树脂与石棉线通过缠绕模压制成的。这种材料在水介质中具有较低的摩擦系数和较好的耐磨与密封性能,其使用寿命优于进口的密封材料。

The authors developed a seal material for an imported turbine unit at Bapan Gorge hydraulic power station. The material was made of oil soaked phenolic and asbostos wire by twisting and moulding process. This material possesses a lower friction coefficient, better wear-resistance and seal ability with water medium. Its service life is superior to that of the imported seal material.
