1、當(dāng)電蒸汽鍋爐http://m.tsgspipe.cn/水位降到水位計最低水位線以下后，通過“叫水”法也未能見到水位時。
When the electric steam boiler water level drops below the minimum level gauge water level, through the "water called" law also failed to see the water level.

2、當(dāng)加大電蒸汽鍋爐補水量水位仍繼續(xù)下降時，給水系統(tǒng)失靈，無法向鍋爐補水時。
When increasing electric steam boiler water level continues to fall up, the water supply system failure, unable to supply water to the boiler.

3、電蒸汽鍋爐水位計及安全閥失靈，無法保證鍋爐安全運行時，當(dāng)排污閥失靈又控制閥關(guān)閉不嚴時。
Electric steam boiler water level gauge and relief valve failure, can not guarantee the safe operation of the boiler, when the drain valve malfunction again when the control valve closed lax.

4、當(dāng)電蒸汽鍋爐http://m.tsgspipe.cn/內(nèi)受壓面或水冷壁管、煙管等出現(xiàn)鼓包或破裂時，爐墻、前拱出現(xiàn)塌倒時，在安全閥失靈情況下，壓力表顯示鍋爐超壓運行時。
When the inner surface electric steam boiler pressure or water wall tube, pipe and other tobacco bulge or rupture occurs, the furnace wall, before falling back arch appears when the safety valve in case of failure, the gauge displays the boiler overpressure runtime.

5、當(dāng)電蒸汽鍋爐超壓時，應(yīng)打開設(shè)在分汽缸上的緊急放空閥進行排放降壓，爐內(nèi)嚴重缺水時，切忌驚慌，以免操作失誤。
When electric steam boiler overpressure, should open in the sub-cylinder emergency vent valve discharge pressure, the furnace severe water shortages, avoid panic, to avoid operational errors.
