【摘要】：分析超声波测厚仪测量灭火器筒体厚度的影响因素,对测量过程中的主要影响因素进行研究。根据超声波测试原理和灭火器筒体的特点,选用Model 25 Multi-plus型超声波测厚仪对灭火器筒体壁厚进行测量。研究表明,影响超声波测厚仪检测灭火器筒体壁厚的主要因素为钢铁种类和测厚仪仪器本身精度。通过对不确定度分量的评定和量化,得到超声波测厚仪测量灭火器筒体常用钢板厚度的合成不确定度和扩展不确定度。测试结果表明,超声波测厚仪对同种牌号灭火器筒体钢板的检测精度可以满足检测标准的精度要求。
[Abstract]:The influence factors of the thickness of the fire extinguisher cylinder measured by ultrasonic thickness meter are analyzed and the main influencing factors in the measurement process are studied. According to the principle of ultrasonic testing and the characteristics of the fire extinguisher cylinder, Model 25 Multi-plus ultrasonic thickness meter is used to measure the wall thickness of the fire extinguisher cylinder. The results show that the main factors affecting the thickness of the fire extinguisher cylinder are the steel type and the precision of the thickness meter. Based on the evaluation and quantification of the uncertainty component, the synthetic uncertainty and the extended uncertainty of the thickness measurement of the fire extinguisher cylinder by ultrasonic thickness meter are obtained. The test results show that the accuracy of ultrasonic thickness meter for the same type of fire extinguisher cylinder steel plate can meet the accuracy requirements of the detection standard.
