【Abstract】 In this paper, the mathematic model of water hammer under the complex pump system is analyzed and a water hammer calculation equation is established. This equation is under the following conditions: water supply from multiple pumps in parallel with a blind pipe to the multiple pipes with different resistance characters. Authors also gave a solution of the non linear doublecurve equation. There 3 accidents of water hammer have happened in this system. Authors made an analogy calculation of these accidents, and the causes of accidents are analyzed.更多还原
