热水采暖与供热管道中的水击计算

Calculation of Water Hammer in Heating Supply Pipeline

热水采暖和供热管道中常会发生水击,严重的水击事故会造成能量的损失及环境的污染。本文按水击发生的模式分类,详细分析了水击发生的原理,论述了各种模式下水击压力的计算公式并辅以计算实例。最后结合实践总结了预防水击的措施。

Water hammer often happens in heating supply pipeline. The serious water hammer can cause resources waste, energy loss and environmental pollution. In this paper, principles of water hammer according to the different happening styles were analyzed, and with examples, the calculation formulas of water hammer pressure on various styles were given out. Finally, several measures to prevent water hammer were summarized based on the engineering practices.
