Description
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“法兰加热器，三个单元，专为大型蒸汽或热水锅炉。他们提供了一个简单的，实用的解决方案，在所有电气锅炉设计中固有的问题：元素放养和现场更换。
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加热器系列大型法兰浸入式加热器提供一个有吸引力的选择，它包含许多元素，因此更难在现场更换更昂贵。通过使用一系列的hx-770加热器元件更换简化；应元件烧坏，它将一个小法兰是必要的。其余的元素可以留在服务。（即使当元件安装在管道法兰浸入式加热器与压缩配件，它通常是不切实际的替代元素后加热器已服役一段时间，由于整个法兰必须被移除元素倾向于有水的存款。成为）
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加热器设置在2-3个/ 8“直径的开口在盲法兰或平封头厚度大于1 / 4。1 2 /八“螺栓固定法兰。横向安装的元件必须以三英尺的间隔支撑。
