摘要
由于现有的管道疏通装置存在清洗不彻底、污水和污染物可能滞留在管道中并且清理所用大量的水不回收导致水资源浪费等缺点,提出了一种基于高压水射流管道疏通的回收系统设计思路。为了探究不同抽吸参数对真空回收系统性能的影响,采用了标准的正交实验法的设计方案,进行真空抽吸系统试验。实验结果表明:在试验的三个影响因素中,对抽吸流量影响大小依次为抽吸高度、真空泵抽吸压力、PVC钢丝管内径,并因此得到了在此试验中的较优方案,可对高压水射流管道疏通的真空回收作业起参考作用。
Because of the problems existing in the pipeline dredging device,such as incomplete cleaning,sewage and pollutants may stay in the pipeline and a large amount of water used for cleaning is not recycled,which would lead to water resource waste,a design idea of recovery system based on the high pressure water jet pipeline dredge is proposed in this paper.In order to explore the influence of different suction parameters on performance of the vacuum recovery system,the standard orthogonal experiment method is adopted to test the vacuum suction system.The results show that the influence of the three factors on the suction flow is the suction height,vacuum pump suction pressure and the inner diameter of PVC steel pipe in turn;the better scheme is then obtained in this experiment.It can be used as a reference for vacuum recovery of high pressure water jet pipeline dredge.
