摘　　要：综合关于水锤的科研成果并结合工程实践经验,以特性线法开发水锤计算程序,模拟水泵启停、事故停泵、阀门快关等工况条件下水泵以及输水管路系统的水锤状况,以计算结果为依据评价设备选型的合理性并提出合理的水锤防护方案,保证运行条件改变或发生事故时水力工况可平稳过渡,实现供水系统运行工况的最优化,确保供水系统安全。Based on the scientific research achievements on water hammer,and combined with engineering practice experience,the water hammer calculation program was developed with the characteristic line method to simulate the water hammer condition of the water pump and water transmission pipeline system under the working conditions of pump start-up and shutdown,emergency pump shutdown and quick valve closing.Based on the calculation results,the rationality of equipment selection was evaluated and a reasonable water hammer protection scheme was put forward,ensuring the smooth transition of hydraulic conditions in case of change of operating conditions or accidents,and realizing the optimization of operating conditions and guaranteeing the safety in the water supply system.
