根据实际工程需要，采用特征线法描述了长距离浆体有压输送管道并联泵系统，尤其是不同类型泵并联的停泵水锤的瞬变过程。结合并联泵系统的边界条件，分别对实际工程的无阀与缓闭阀管路进行了计算并分析比较，得出缓闭阀管路比无阀管路有利。最后综合防护的总体考虑，对停泵水锤的防护提出了相应建议。

In this paper,according to actual needs of the project,by the characteristic line method described in long distance slurry pressure pipeline parallel pumps system,especially the different types of pumps in parallel pump water hammer transient process. Combined with the parallel pump system boundary conditions,respec-tively,on the actual project without valve,slow closing valve pipeline were calculated and compared,the slow closing valve pipeline than without valve pipeline favorable. Finally,comprehensive protection general consider-ation,the corresponding suggestions on water hammer protection proposed.
