电热水锅炉采暖系统出现水击怎么回事?

电热水锅炉http://www.jnshengxin.cn/采暖系统有时会产生强烈的水击现象,在出水管道或回水管道上发出撞击声,同时伴随管道的强烈振动,严重时可听到散热器的爆破声,这是怎么回事呢?如何避免这种现象呢?

电热水锅炉厂家分析说出现这种现象的主要原因是管路里存有气体。一种可能是系统缺水吸气,或者是热水中的溶解空气析出,或者是由于管路中局部地区水压降低至该处热水温度下的汽化压力以下,使部分热水局部汽化。另一个可能是系统循环泵停止运行时锅水汽化,系统循环泵突然停运。由于高速流动循环水立即停止流动,强大的速度能变为压力能,而使主回水管循环水泵吸入端压力急剧升高,产生强烈水击。
Electric water boiler manufacturers analysts say the main reason for this phenomenon is there in the gas pipeline. One possibility is that the system water intake, or precipitation of dissolved air in hot water, or due to the pipeline pressure decreases to some areas where the vapor pressure of the hot water temperature below, so that part of the hot water partial vaporization. Another possibility is that the system circulating pump stops running when the pot of water vapor, the system circulating pump sudden outage. Due to the high-speed flow of circulating water immediately to stop the flow, a strong pressure can speed can be changed, leaving the main return pipe circulating pump suction side pressure increased sharply, resulting in a strong water hammer.

电热水锅炉http://www.jnshengxin.cn/建议出现这种情况时应该减弱燃烧,降低炉膛温度、打开放气阀打开锅炉出口处的泄放管阀门,在循环水泵的压力管路和吸水管路之间连接一根带有止回阀的旁通管作为泄压管如水击严重,造成低点近端散热器破裂和对丝堵弯头等连接件撕裂,应紧急停炉。
Electric water boiler recommend this occurs should weaken combustion, reducing the furnace temperature, play an open vent pipe valve opens at the boiler outlet valve between the pressure line and the circulating pump suction line connection with a stop back pressure relief valve bypass pipe water pipe as a serious blow, resulting in low proximal rupture and sink plugs and other connectors torn elbow, should an emergency shutdown.
