KINEMATICS ANALYSIS OF THE 7NB MUD BUMP

介绍了一种钻井用新型泥浆泵— 7NB泥浆泵的结构特点、工作机理和研究情况等。采用机械设计自动化软件(Pro/E)建立了 7NB泥浆泵三维实体模型和运动学模型 ,实现了对 7NB泥浆泵主要运动部件的运动学分析计算。通过简化结构 ,建立了 7NB泥浆泵的运动方程和解析计算模型 ,进行了对比分析计算。通过计算找到了 7NB泥浆泵的运动规律、运动特点 ,为进一步改进 7NB泥浆泵的结构和工作性能提供了理论依据。

In this paper, the structure and working principle of the new drilling mud bump-7NB mud bump were introduced. The kinematics model and 3D entity model were established with the CAD software (Pro/E), the kinematics analysis of the 7NBs mainly moving parts were finished. By simplification of the structure, the Moving equation and computation model of the 7NB were established, the analysis and calculating completed. The moving characteristics and principles were found through computing. It provided the theory foundation for improving the structure and working principal of the 7NB mud pump.
