1）冷却不足。冷却系统故障如水泵磨损泄漏、传动带松动断裂，散热器和冷却水道水垢严重，节温器卡死或动作值偏移等，使机得不到及时冷却，活塞、缸套始终处于高温状态而烧蚀。冷却器喷嘴堵塞也是造成活塞烧蚀的重要原因。2）空气弗列加滤清器滤芯脏堵。空滤滤芯堵塞会导致进气量减少，无法满足喷入缸内完全燃烧的需要而形成后燃，使机冒黑烟，气缸内温度过高。3）全负荷工作运行时突然停机。或机在全负荷工作运行时突然停机，冷却系统随之停止工作运行，则活塞可能因热量无法正常散出而局部烧蚀。4）润滑不当。润滑油选择不当，或润滑系统故障会使磨损加剧或燃烧室润滑油和积炭增多而恃致活塞拉缸或烧蚀。5）排气背压大。若消声器堵塞造成排气不畅，会有高温燃气在缸盖等处积聚，使燃烧室部件长期处于高温状态，从而造成活塞烧蚀。6）燃油系统故障。喷油量过大或雾化不良，造成积炭和缸内异常高温，严重时使活塞烧蚀。喷油提前角不正确，PT燃料系统STC阀柱塞磨损或卡死，以及STC润滑油油路泄漏等，都将导致喷油正时紊乱，燃烧不好，活塞积炭高温烧蚀。深圳茂名干式变压器厂家7）其他。缸套和活塞腐蚀、气蚀破坏；制造缺陷形成疲劳源导致疲劳损坏；活塞顶隙调整不当，使机压缩比发生变化等原因也会导致拉缸或活塞烧蚀。动力设备（深圳）有限公司隶属于集团旗下茂名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茂名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，根据茂名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，请登录茂名干式变压器官网首页：
