摘要
介绍了国内外旋转控制头的类型，对比分析了锥形胶芯型和膨胀胶囊型旋转控制头的性能特点，指出旋转控制头的其发展方向是密封等级升高、轴承总成的锁紧方式采用液动方式和设置单独的高压润滑装置。
The paper made an introduction to rotating heads world wide used in fields. A contrast between conical rubber core and expansion rubber bag types was given,and the developing trend of rotating heads was studied.
