摘　　要：根据煤层气专用旋转控制头润滑冷却系统要求,结合现有成熟旋转控制头润滑冷却技术,设计出无外挂冷却润滑泵站式结构。为保证该结构满足旋转控制头密封系统、轴承组的润滑冷却要求,利用有限元分析软件和室内实验对旋转控制头润滑冷却系统进行热力学分析。结果表明:该润滑冷却系统满足设计要求,其中上扶正轴承温度最高,最高温度可达71.9℃,动密封组件最高温度达60℃。此外,偏心距、密封压力、转速对润滑冷却系统影响较大,系统温度与上述三个因素近似成线性变化。According to the requirements of the CBM special rotary control head lubrication and cooling system and combined with the existing mature rotary control head lubrication cooling technology,this paper designed a structure without cooling and lubricating pump station plugins. In order to ensure the structure satisfies the lubrication and cooling requirements of the rotary control head sealing system and bearing group,this paper applied the finite element analysis software and indoor experiment to carry out the thermodynamic analysis on the rotary control head lubrication and cooling system. The results show that the lubrication and cooling system meets the design requirements. The upper stabilizing bearing temperature is highest which is 71. 9 ℃ while the highest temperature of the dynamic seal assembly is 60℃. In addition,eccentricity,sealing pressure and rotating speed have greater impact on the lubrication and cooling system,the system temperature changes with the above three factors similarly to a linear change.
