机故障产生的过程故障产生的过程实际上是一个积累与变化的过程，即零部件强度（技术状况）逐渐变化下降的过程。渐发性故障多由磨蚀性磨损、咬接性磨损、点蚀磨损、机械腐蚀磨损等形式出现。另外，腐蚀故障（包括应力腐蚀、气蚀、硫蚀、钒蚀等）也属于渐发性故障。
突发性故障是当零件的强度低于外界载荷时才会发生。零件在初始工作运行阶段，强度变化较小，当外界载荷突然超过零件强度时，就会产生突发性故障，这种突发性故障是在外界载荷的意外峰值下偶然发生的。如机飞机组造成连杆螺栓断裂、挺杆脱落等。突发性故障多以疲劳、过度变形等形式出现。除了如上所述由于零件强度（技术状况）和外界载荷的原因以外，润滑系统、冷却系统的堵塞和泄露也会造成突发性故障动力设备（深圳）有限公司隶属于集团旗下汕头干式变压器组业务中国区服务提供商，主要运营东风和两大品牌在中国的汕头干式变压器组产品的出售租赁、维修保养及其售后服务。为军工企业、工厂矿业、商场超市、地产酒店、建筑施工、桥梁隧道、活动演出、娱乐会所演唱会供应紧急和长期后备应急电源，根据汕头干式变压器组其功能区分为：移动式、固定式、超静音式、机组载式发电设备。常见功率（千瓦）范围：50KW,,150KW,200KW,250KW,300KW,400KW,500KW,800KW,1000KW等功率段。更多有关的最新产品和技术内容，请登录汕头干式变压器官网首页：
