Abstract
In tackling velocity fluctuation and insufficient detection accuracy of detectors in small-diameter pipelines under high gas flow rates,a speed control unit applicable to inspection tool of small diameter pipeline was developed.Firstly,the principle of speed control and construction characteristics were given.By analyzing the operation mechanism of the speed control unit,the transfer function between its operation speed and the opening degree of the drain valve was obtained.Secondly,by integrating an interval PID control strategy with feedback closed loop,the convergence and graded regulation of the operation speed were realized.Subsequently,based on the principle of fluid dynamics,the speed reduction capability of speed control unit was obtained by simulation and analysis.Finally,the speed control unit was tested by the loop test field,and the maximal fluctuation of its speed is 22.75%of the interval difference,and the maximal response time is about 7.6 s.The results indicate that the developed speed control unit can effectively control the detector speed and enhance accuracy of inspection tool.关键词
