【摘要】 针对目前传统清管器容易被堵塞的缺陷,研制一种新型清管器———液压水射流清管器。该清管器能最大限度避免在管道中被堵塞的风险。它由1个制动单元、1个密封单元和1个清洁头组成。制动单元能确保清管器以较稳定的速度向前运动;清洁头能把部分带压水转化成冲击力较强的水射流,把管道前面的污垢冲稀带走。实验证明:该新型清管器性能测试符合设计要求,有很好的市场应用前景。更多还原

【Abstract】 Based on the traditional pipe-pig flaw,this paper has developed a new type of pipe—pig,namely the hydraulic water jet pipe-pig(HAPP).HAPP can avoid the risk of clogging in the pipeline as much as possible.It consists of a brake unit,a sealing element and a cleaning head.Brake unit can ensure the pipe-pig a more stable speed of movement;the cleaning head can ensure the partial pressure of the water into the impact of strong water jet.Experiments show that HAPP meet the design requirements.更多还原
