热水供热管网发生水击现象是热网运行中存在的实际问题。一旦发生,不仅对管道及设备有一定的破坏能力,严重时还会危及到人身安全。所以水击是热网运行中不可忽视的问题。对水击的概念、产生原因及传播过程进行了相应的论述,给出了水击强度的计算公式,就热网运行中水击的防护措施进行了探讨。 Hot water heating pipe network water hammer phenomenon is the existence of practical problems in heating network. Once occurred, not only has some damage to the pipelines and equipment, but also endangers personal safety in serious cases. So water hammer is hot network operation can not be ignored problem. The concept of water hammer, its causes and propagation process are discussed correspondingly. The calculation formula of water hammer strength is given, and the protection measures of water hammer in heat network operation are discussed.
