大型集中空调循环水系统停泵水锤成因分析及防护

Analysis on the Cause of Pump-off Water Hammer in Large-scale Concentrated Air-Conditioning Circulating Water System and Controlling Measures

从停泵时回水和供水对水泵及止回阀造成的压力脉冲角度,分析了空调循环系统水锤产生的过程和原因,指出了大型空调水系统水锤的严重危害,给出了水锤压力估算的基本方法,并从设计和运行等方面介绍了防治和消除水锤现象的措施.

The process and cause of the water hammer in air conditioning circulating water system as well as the severe undermines brought by it are analyze and check valve caused by water return and water d in this paper from the view point of pressure pulse on pump supply as pump fail. Furthermore, mate the water hammer pressure is given out. The measures to pravent and eliminate non are introduced from design and running. the basic method to esti water hammer phenome
