Abstract

The paper presents the developed mathematical model of a spring electric drive with a multi-functional ability of the defectoscope, which has increased selectivity and resolution to the technological defects of the controlled product (oil and gas pipelines, their welds). The work of the spring electric drive for defectoscopes (SED) is based on the fact that the resistance to magnetic flux changes when longitudinal and transverse defects appear on the inner and outer surfaces of the product. As a result of this effect, when the SED moves inside the product on the spring winding as a result of changes in the circuit current, a signal appears that determines the location and parameters of the defects. The technical capabilities of this drive - defectoscope allow us to investigate the detected defects at the following metrological parameters: error in measuring the wall thickness of the tube 0.4 mm; minimum length of the defect type “crack” along the axis of the pipe 40 mm; minimum length of the defect type “transverse crack” 1/6 of the circumference, versatility.

缺陷检波器弹簧传动

建立了具有多功能缺陷检测功能的弹簧电传动的数学模型，提高了对被控产品(油气管道及其焊缝)工艺缺陷的选择性和分辨率。弹簧电驱动探伤器的工作原理是:当产品内外表面出现纵向和横向缺陷时，其对磁通的电阻会发生变化。由于这种影响，当SED由于电路电流的变化而在弹簧绕组上的产品内部移动时，就会出现一个信号，该信号决定了缺陷的位置和参数。这种驱动缺陷镜的技术能力使我们能够在以下计量参数下研究检测到的缺陷:测量管壁厚的误差为0.4 mm;缺陷型“裂纹”沿管道轴线的最小长度为40mm;缺陷型“横向裂纹”的最小长度为周长的1/6，通用性强。
