摘　　要：目的分析中国疾病预防控制中心实验动物中心ABSL-2实验室蒸汽管道系统水锤现象产生的原因,提出解决对策。方法根据该ABSL-2实验室蒸汽管道系统的基本情况,阐述管道设计、疏水器选型、疏水点位置、设置集水槽、人为操作等几方面是产生水锤现象的基本因素,逐一分析其影响程度,以确定科学有效地削减水锤现象的方法。结果通过合理设计、正确选择疏水装置、合理设置疏水点、疏水器前端设置集水槽、规范系统运行规程,以消除蒸汽运行过程中的管道震动、运行噪声,设备堵塞,阀部件破坏等现象,进一步提高实验动物中心ABSL-2实验室蒸汽管道系统的安全性、稳定性。结论采取有效可行的对策,减少实验动物中心ABSL-2实验室蒸汽管道系统水锤现象的发生,提高生物安全实验室保障水平,并为今后实验动物中心蒸汽管道系统的设计和管理提供可借鉴的经验。Objective To analyze the causes of water hammer in the steam pipe system of laboratory animal center ABSL-2 laboratory,and to put forward some solutions.Methods The basic situation of laboratory animal center steam piping system was analyzed.In view of pipeline design,type selection of trap,location of hydrophobic point,set water tank,artificial operation and so on,in-depth analysis was carried out.Results Due to the unreasonable pipeline design,the incorrect selection of the trap,the reasonable location of the drainage point,set up the sump and standardize system operation rules to eliminate pipeline vibration,running noise,equipment blockage,valve companent damage and so on daring steam operation. Through the design of reasonable diameter and inclination,according to the steam trap,the right way to choose the hydrophobic binding position,hydrophobic front-end pipeline set a reasonable set of water tank,start the installation of electronic control valve and other measures,scientifically and effectively solved water hammer steam pipe system.Conclusion Effective and feasible measures should be taken to reduce the occurrence of water hammer in pipe system of laboratory animal center ABSL-2 laboratory and improve the level of biosafety laboratory guarantee,provide some experience for future design and management of experimental animal center steam piping system.
