X射线探伤机能准确地检测物体内部缺陷,广泛地应用于机械、冶金、化工、石油、军工等部门,在无损检测仪器中占有很大的比重。现将各类X射线探伤机的发展动向概要介绍如下。 1.携带式探伤机这类探伤机主要用于施工现场,要求体积小、重量轻、操作运输方便可靠。为了减轻携带式探伤机的重量,国外有的公司采用了高频变压器、新型X射线管,改用气体绝缘和冷却,采用新的电器材料和防护材料。在高
X-ray flaw detection function can accurately detect internal defects, widely used in machinery, metallurgy, chemical industry, petroleum, military and other departments, occupy a large proportion of non-destructive testing instruments. Now all kinds of X-ray flaw detector development trend outlined below. 1. Portable Flaw Detector This type of flaw detector is mainly used in the construction site, requiring small size, light weight, convenient and reliable operation and transportation. In order to reduce the weight of portable inspection machine, some foreign companies have adopted high-frequency transformers, new X-ray tube, switch to gas insulation and cooling, the use of new electrical materials and protective materials. At high
