我厂是1986年开始设备状态监测和故障诊断技术工作的。几年来通过对生产缸套毛坯的离心浇注机进行多台长期的状态监测、维修,取得了较为满意的经济效益和维修效果。 这是我们从传统的维修方式向预防维修方式过渡的一种成功尝试。1 状态监测和测试原理 离心浇注机的主轴承载在326K和7222E轴承上,滚动轴承是该机最易损坏的零件,常见故障有磨损、压痕、裂纹、表面剥落、胶着、烧损、锈蚀等。 Our factory started in 1986, equipment condition monitoring and fault diagnosis technology. Over the past few years through the production of cylinder blank centrifugal casting machine for multiple long-term status monitoring, maintenance, and achieved more satisfactory economic benefits and maintenance results. This is a successful attempt at our transition from a traditional maintenance mode to a preventive maintenance mode. 1 Condition Monitoring and Testing Principle Centrifugal casting machine’s main bearing on the 326K and 7222E bearings, rolling bearings are the most vulnerable parts of the machine, the common faults are wear, indentation, cracks, surface peeling, adhesive, burning, corrosion and so on.
