| Abstract: | Air surge tank and slow-closing back pressure valve are installed in the long-distance water delivery system of pump. Experiment model and relevant mathematic model are built to make the theoretical analysis, numerical and experimental study on the models. The mathematic simulation and mathematic model are verified by experiments. The appropriate place for using slow-closing back pressure valve is designated,and erroneous place for using this valve is corrected. It is significant in improving the safety of the water delivery system and lowering the cost of the project. |
