| 摘 要： | 应用水压图分析了３个实例,说明在同程式中如有倒流现象,管道必有异物堵塞;有倒流必定有强流,堵塞部位在倒流与强流之间,若倒流在强流之后,则异物堵塞在供水管道,反之,则异物堵塞在回水管道。

| Abstract: | Illustrates with a pressure diagram analysis of three examples that if backflow occurs in the reversed return system, always coincident with a strong flow, there must exist a solid blockage in the pipeline. A backflow occurring downstream of the strong flow indicates the solid blockage in the water supply pipe. Otherwise, the solid blockage must be in the return pipe. |
