電熱水鍋爐http://www.tsgspipe.cn/進(jìn)水溫度應(yīng)保持在20－30℃左右，溫度過(guò)低而使鍋爐外壁凝有露水，與發(fā)生滲水等不嚴(yán)密情況會(huì)混淆不清，增加檢查困難，溫度太高能使水滴蒸發(fā)，使?jié)B漏處不被發(fā)現(xiàn)。電熱水鍋爐水上滿后，逐漸升高壓力進(jìn)行一次嚴(yán)密性檢查，必要時(shí)緊一次法蘭、人孔門和手孔蓋的螺母。水壓試驗(yàn)時(shí)，水壓應(yīng)緩慢上升，當(dāng)水壓上升到試驗(yàn)壓力0.2MPa時(shí)，保持20分鐘，若壓力沒有下降，降至工作壓力0MPa進(jìn)行檢查。
Electric hot water boiler water temperature should be maintained at about 20-30 ℃, leaving the boiler temperature is too low outer condensate dew, and the occurrence of the situation will not tight water seepage confusion, increased inspection difficult, the temperature is too high to make the water droplets evaporate, so no leaks were found. After the electric water boiler water filled, gradually increasing the pressure to conduct a rigorous examination, a tight flange, Manhole and hand-hole cover nuts if necessary. When the pressure test, pressure should rise slowly, when the pressure rises to the test pressure 0.2MPa, keep 20 minutes, if the pressure does not drop down to the working pressure 0MPa be checked.

電熱水鍋爐http://www.tsgspipe.cn/水壓試驗(yàn)符合下列情況，即認(rèn)為合格： 在受壓元件金屬和焊縫上沒有水珠和水霧；水壓試驗(yàn)后，無(wú)可見的殘余變形。
Electric hot water boiler pressure test meet the following conditions, namely that the eligibility: No water droplets and mist in the compression element metal and welds; after hydrostatic testing, no visible residual deformation.
