基于水锤现象的建筑给水系统防护措施

Protective Measures for Building Water Supply Systems Considering Water Hammer Phenomenon

为有效进行水锤防护,提升建筑给水系统运行的安全性、可靠性,对建筑给水系统的水锤现象进行分析,并以不同角度对水锤现象进行划分,明确了水锤现象的诱因。同时,从水锤波速、水锤的基本微分方程、特征线方程求解方法三方面,阐述了水锤特征值的计算方法。基于此,以合理选择给水方式、气压水罐防护、其他防护措施为切入点,提出建筑给水系统的水锤防护措施,并结合福安某私人住宅给水系统设计案例,对案例所采取的水锤防护措施进行分析。

To ensure the safety and reliability of building water supply systems and effectively mitigate water hammer effects,this paper investigates water hammer phenomena in building water supply systems from various perspectives,identifying the causes of water hammer.It further explains the calculation methods for water hammer characteristic values,including wave velocity,the basic differential equation,and solution approaches for characteristic equations.Building upon these findings,the paper proposes water hammer protection measures for building water supply systems,emphasizing the selection of appropriate water supply modes,pneumatic water tank protection,and other preventative measures.The analysis includes a case study of a private residential water supply system in Fu'an,highlighting the applied water hammer protection measures.
