電熱水鍋爐采暖系統出現水擊怎么回事?

電熱水鍋爐http://www.hbyuandong.com.cn/采暖系統有時(shí)會(huì )產(chǎn)生強烈的水擊現象,在出水管道或回水管道上發(fā)出撞擊聲,同時(shí)伴隨管道的強烈振動(dòng),嚴重時(shí)可聽(tīng)到散熱器的爆破聲,這是怎么回事呢?如何避免這種現象呢?

電熱水鍋爐廠(chǎng)家分析說(shuō)出現這種現象的主要原因是管路里存有氣體。一種可能是系統缺水吸氣,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)可能是系統循環(huán)泵停止運行時(shí)鍋水汽化,系統循環(huán)泵突然停運。由于高速流動(dòng)循環(huán)水立即停止流動(dòng),強大的速度能變?yōu)閴毫δ?,而使主回水管循環(huán)水泵吸入端壓力急劇升高,產(chǎn)生強烈水擊。
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.

電熱水鍋爐http://www.hbyuandong.com.cn/建議出現這種情況時(shí)應該減弱燃燒,降低爐膛溫度、打開(kāi)放氣閥打開(kāi)鍋爐出口處的泄放管閥門(mén),在循環(huán)水泵的壓力管路和吸水管路之間連接一根帶有止回閥的旁通管作為泄壓管如水擊嚴重,造成低點(diǎn)近端散熱器破裂和對絲堵彎頭等連接件撕裂,應緊急停爐。
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.
