我厂有一台CEW-10000型交直两用磁粉探伤机,用于内燃机车柴油机检修时曲轴探伤。现场使用中往探伤机上吊装曲轴不方便。这是因纵向磁化线圈内径为600mm,曲轴最大旋转直径为440mm,间隙较小所致,造成装卸曲轴时得谨慎小心,避免曲轴与线圈碰撞,而且检查连杆颈时也不方便。受原设计的磁化通电方式所限,工作过程中,要想 I plant a CEW-10000-type AC and DC magnetic particle inspection machine for diesel locomotive diesel engine inspection crankshaft testing. In the field of using the test machine to lift the crankshaft is not convenient. This is because the longitudinal magnetizing coil has an inner diameter of 600 mm and a maximum crankshaft rotation diameter of 440 mm, resulting in a small clearance. Caution should be exercised when handling the crankshaft to avoid collision of the crankshaft with the coil and inconvenience in checking the connecting rod neck. By the original design of magnetizing power limited, work process, to think
