摘要:
在漏磁、电磁超声以及脉冲涡流检测原理上，设计电站锅炉水冷壁磁声复合检测传感器，该传感器由磁敏元件、线圈、永磁体、衔铁等组成，采用外圈发射内圈接收形式进行工作。通过仿真试验模拟，对传感器的参数进行了优化确定，得出如下结论：漏磁的最佳磁场强度为15 kA/m，电磁超声和脉冲涡流的最佳磁场强度为28 kA/m；发射线圈和接收线圈的直径分别为0.08 mm和0.05 mm，最佳匝数分别为20和30匝；磁敏元件和复合检测线圈的最佳提离距离分别为3 mm和0. 5mm。通过对不同宽度和深度的缺陷检测，该磁声传感器的平均检测误差均小于5%，具有良好的工作性能，可在生产实践中予以应用。
Abstract:
Based on the principle of magnetic flux leakage, electromagnetic ultrasonic and pulsed eddy current detection, this paper designs a composite Magnetoacoustic detection sensor for water wall of power plant boiler, which is composed of magnetic sensor, coil, permanent magnet, armature, etc., and works in the form of outer ring transmitting and inner ring receiving. Through simulation test, the parameters of the sensor are optimized and determined. The conclusion is as follows: the best magnetic field intensity of magnetic flux leakage is 15ka / m, the best magnetic field intensity of electromagnetic ultrasonic and pulse eddy current is 28ka / M; the diameters of transmitting coil and receiving coil are 0.08mm and 0.05mm respectively, and the best turns are 20 and 30 turns; the best lift off distance of magnetic sensor and composite detection coil is 20 and 30 turns respectively 3mm and 0.5mm. Through the defect detection of different width and depth, the average detection error of the Magnetoacoustic sensor is less than 5%, which has good performance and can be applied in production practice.
