電熱水鍋爐水壓試驗

電熱水鍋爐http://www.nys3.com/進水溫度應保持在20-30℃左右,溫度過低而使鍋爐外壁凝有露水,與發生滲水等不嚴密情況會混淆不清,增加檢查困難,溫度太高能使水滴蒸發,使滲漏處不被發現。電熱水鍋爐水上滿后,逐漸升高壓力進行一次嚴密性檢查,必要時緊一次法蘭、人孔門和手孔蓋的螺母。水壓試驗時,水壓應緩慢上升,當水壓上升到試驗壓力0.2MPa時,保持20分鐘,若壓力沒有下降,降至工作壓力0MPa進行檢查。
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.nys3.com/水壓試驗符合下列情況,即認為合格: 在受壓元件金屬和焊縫上沒有水珠和水霧;水壓試驗后,無可見的殘余變形。
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.
