| The
inner inspection tool move based on the liquid or gas pressure differential
in the oil pipeline to inspect the defect of the pipe. In order to improve
the detection precision, the inspection tool should keep constant speed and
robust state in different situation. This paper established the model of
inner inspection tool based on drainage hole. Though analyzing the driving
force and the frictional resistance of the inspection tool, get the
relationship between the size of Drainage hole and the speed in some certain
situation. This paper also use the Fluent to analyze that how the different
shape of the drainage hole and different number of the hole influence the
turbulence intensity of the flow field around the tool. Getting that when the
drainage was center gradually broad, the kinestate of the inspection tool is
more robust. 管道内检测工具的速度控制研究 |
