一种自动化磁粉检测系统的研制

Development on an Automatic Magnetic Particle Testing System

随着大型承压特种设备应用的逐渐普及,对设备的无损检测技术提出了更高要求。传统的磁粉检测技术需要人工进行探伤作业,针对大型承压特种设备的检测,往往需要设置辅助检测设施。对于设备内部焊缝检测,由于大型承压类特种设备承载介质有毒有害,且内部采光条件也十分恶劣,因此对大型承压特种设备实施传统的磁粉检测给探伤人员带来了较大的挑战,不利的检测条件,也易致使检测人员时常出现漏检或误判现象。研究提出了一种根据检验人员需求,可实现在远程控制条件下对大型承压特种设备进行自动化检测的磁粉探伤设备,为保障国内检测人员安全及提高磁粉检测数据有效性提供了解决方案。

With the popularization of the application of large pressure special equipment,higher requirements are put forward for the nondestructive testing technology of equipment.The traditional magnetic particle testing technology requires manual flaw detection.For the detection of large pressure special equipment,auxiliary testing facilities are often required.For the internal weld inspection of equipment,because the bearing medium of large-scale pressure special equipment is toxic and harmful,and the internal lighting conditions are also very bad,the traditional magnetic particle testing of large-scale pressure special equipment has brought great challenges to the flaw detection personnel,and the adverse testing conditions are also easy to make the detection personnel often miss or misjudge.According to the requirements of inspectors,a kind of magnetic particle testing equipment was proposed,which can realize the automatic testing of large pressure special equipment under remote control.It provides a solution for ensuring the safety of domestic inspectors and improving the effectiveness of magnetic particle testing data.
