在我市的一些小型企业和学校中安置使用卧式水管手烧锅炉(WS DH型,D=0.2—0.5t/h,P=0.09-0.7MPa)的逐渐增多,据本人了解,这种型式的锅炉在给水时均会有水击现象发生。产生水击现象的原因是锅炉的进水口位置设置不合理。这种型式的锅炉的进水口位置设置在水位线以上的汽空间里,见图1所示。在锅炉停止给水期间,进水管1内充满了蒸汽,因此当锅炉重新给水时,较冷的
In some small enterprises and schools in our city, horizontal water-pipe burners (WS DH type, D = 0.2-0.5t / h, P = 0.09-0.7MPa) were gradually installed. As far as I know, this type Of the boiler in the water will have a water hammer phenomenon occurs. The reason for the water hammer phenomenon is that the position of the water inlet of the boiler is not set properly. The inlet of this type of boiler is located in the vapor space above the water level, as shown in Figure 1. During the period when the boiler stopped supplying water, the water inlet pipe 1 was filled with steam, so when the boiler was re-supplied with water, colder
