描述
Series HX-770 – 4-7/8″ flange heaters, are three-element modules specifically designed for large steam or hot water boilers. They offer a simple, practical solution to two problems inherent in all electric boiler designs: element stocking and field replacement.
系列hx-770 4-7 / 8“法蘭加熱器，三個單元，專為大型蒸汽或熱水鍋爐。他們提供了一個簡單的，實用的解決方案，在所有電氣鍋爐設計中固有的問題：元素放養和現場更換。
Series HX-770 heaters offer an attractive alternative to large pipe flange immersion heaters, which contain a multitude of elements and are therefore more difficult and more expensive to replace in the field. By using Series HX-770 heaters, element replacement is simplified; should an element burn out, it is only necessary to remove one small flange. The rest of the elements can remain in service. (Even when the elements are mounted into a pipe flange immersion heater with compression fittings, it is usually impractical to replace an element after the heater has been in service for some time, as the entire flange must be removed and elements tend to become encrusted with water deposits.)
hx-770加熱器系列大型法蘭浸入式加熱器提供一個有吸引力的選擇，它包含許多元素，因此更難在現場更換更昂貴。通過使用一系列的hx-770加熱器元件更換簡化；應元件燒壞，它將一個小法蘭是必要的。其余的元素可以留在服務。（即使當元件安裝在管道法蘭浸入式加熱器與壓縮配件，它通常是不切實際的替代元素后加熱器已服役一段時間，由于整個法蘭必須被移除元素傾向于有水的存款。成為）
Series HX-770 heaters are installed through a 2-3/8″ diameter opening in a blind flange or a flat boiler head having a minimum thickness of 1-1/4″. Eight 1/2″ bolts hold the flange in place. Horizontally mounted elements must be supported at three-foot intervals.
系列hx-770加熱器設置在2-3個/ 8“直徑的開口在盲法蘭或平封頭厚度大于1 / 4。1 2 /八“螺栓固定法蘭。橫向安裝的元件必須以三英尺的間隔支撐。
