自进式管道清洗喷头的喷嘴布置
|
摘要
自进式旋转喷头是管道清洗用高压水射流清洗装置的关键执行部件,为了保证自进式旋转喷头在管道清洗过程中能够稳定地自进和旋转,分析了自进式旋转喷头的喷嘴数目、夹角及偏心量对其运动和清洗效果的影响,通过对比旋转式喷头与非旋转式喷头、无偏心喷头的喷嘴布置及清洗效果,得出结论:喷嘴数目、夹角及偏心量是保证喷头自进和旋转的关键,且三者之间相互关联,进而分析了喷嘴布置设计的要点。基于此,提出了一种合理高效旋转喷头的喷嘴布置方式,既能使自进式旋转喷头稳定运动,又能提高高压水清洗的效率。(图5,参21)
Self-propelled rotary sprinkler is the key executive component of the high-pressure water jet cleaning device used in the operation of pipeline cleaning. To ensure that the self-propelled rotary sprinkler can self-propel and rotate stably in the process of pipeline cleaning, the influence of the layout factors(i.e., number of nozzles, included angle and eccentricity) on the movement and cleaning effect of the self-propelled rotary sprinkler was analyzed in this paper. Then, rotary sprinkler,non-rotary sprinkler and eccentricity free sprinkler were compared from the aspects of nozzle layout and cleaning effect. It is concluded that the number of nozzles, the included angle and the eccentricity are the key factors to ensure the self-propelling and rotating of the sprinkler and they are interdependent. Finally, the key design points involved in nozzle layout were put forward. In this way, a reasonable and efficient method for the layout of nozzles in rotary sprinklers is developed, which can ensure the stable movement of the self-propelled rotary sprinkler, and improve the efficiency of high-pressure water cleaning.(5 Figures, 21 References)
