電熱水鍋爐http://m.officechairs.com.cn/采暖系統(tǒng)有時(shí)會(huì)產(chǎn)生強(qiáng)烈的水擊現(xiàn)象，在出水管道或回水管道上發(fā)出撞擊聲，同時(shí)伴隨管道的強(qiáng)烈振動(dòng)，嚴(yán)重時(shí)可聽(tīng)到散熱器的爆破聲，這是怎么回事呢？如何避免這種現(xiàn)象呢？
電熱水鍋爐廠(chǎng)家分析說(shuō)出現(xiàn)這種現(xiàn)象的主要原因是管路里存有氣體。一種可能是系統(tǒng)缺水吸氣，或者是熱水中的溶解空氣析出，或者是由于管路中局部地區(qū)水壓降低至該處熱水溫度下的汽化壓力以下，使部分熱水局部汽化。另一個(gè)可能是系統(tǒng)循環(huán)泵停止運(yùn)行時(shí)鍋水汽化，系統(tǒng)循環(huán)泵突然停運(yùn)。由于高速流動(dòng)循環(huán)水立即停止流動(dòng)，強(qiáng)大的速度能變?yōu)閴毫δ埽怪骰厮苎h(huán)水泵吸入端壓力急劇升高，產(chǎn)生強(qiáng)烈水擊。
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.

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.
