本文介绍一种适合在火力发电厂,对锅炉内部水冷壁管、过热器管、省煤器管进行X射线照相时用的X射线探伤机支架。它不需要电源,也不需要用螺丝夹紧,只要挂在相邻二侧的管子上,利用X射线探伤机的自重,就能使它牢靠地固定在管道上。简易X射线探伤机支架,不但适宜在立式管道上使用,也适宜在卧式管道上使用。简易式支架用25×3mm的扁钢焊接制成,总重量为4kg。支架由挂钩、撑脚和机架组成。机架的圆弧正好与X射线探伤机壳的外圆相等。挂钩和撑脚处的圆弧,为了能使“三管”通用,故取水冷壁管外圆尺寸,因为省煤器管和过热器管的外径均小于水冷壁管。但
This article introduces a suitable X-ray flaw detector bracket for X-ray photography of water-cooled wall tubes, superheater tubes and economizer tubes in a thermal power plant. It does not require power, do not need to use the screw clamp, as long as hanging on the adjacent two sides of the tube, the use of X-ray testing machine’s own weight, it can make it firmly fixed in the pipeline. Simple X-ray flaw detector bracket, not only suitable for use on vertical pipe, but also suitable for use on horizontal pipe. Simple bracket with 25 × 3mm flat steel welded together, the total weight of 4kg. Bracket by the hook, legs and rack composition. The circular arc of the rack is exactly equal to the outer circle of the X-ray detector housing. Hooks and legs at the arc, in order to make “three ” common, so take the water wall tube size, because the economizer tube and superheater tube diameter are smaller than the water wall tube. but
