摘要
本文详细分析了GE Signa HDe 1.5 T磁共振在使用过程中发生的梯度水冷机故障和数据库故障,并提出了具体的排除方法和解决方案。通过对两例故障的深入研究,采取自主维修的方法,明确故障原因。针对梯度水冷机内部电机联动接头断裂故障,测量配件尺寸,通过代加工或者3D打印技术加工配件并更换;针对数据库故障,更改用户登录名进入root模式,以此突破厂家维修密钥的限制,重建数据库后解决故障。采取科学有效的维修方法,以最小的成本及时有效地解决故障,不仅成本低、耗时短、效率高,而且也大大提高了工程师的维修水平和实践能力,同时为同行维修此类故障提供了参考。
This paper analyzed the faults of gradient water cooler and database in the process of using GE Signa HDe 1.5 T magnetic resonance in detail,and put forward the specific troubleshooting methods and solutions.Two cases of fault were studied deeply,and the self-maintenance method was adopted to clarify the fault cause.In view of the fracture fault of the internal motor linkage joint of the gradient water cooler,the size of the accessory was measured and processed by OEM or 3D printing technology and replaced.In view of the database fault,the user’s login name was changed to enter the root mode,so as to break through the limitation of the manufacturer’s maintenance key,and solve the fault after rebuilding the database.Scientific and effective maintenance methods are adopted to solve the faults timely and effectively with the minimum cost,which not only has low cost,short time consuming and high efficiency,but also greatly improves the maintenance level and practical ability of engineers.At the same time,it provides a reference for peers to repair such faults.
