拉缸是指气缸与活塞或活塞环相对运动时表面形成严重损伤。一般多发生在新机或大修后的初期。（1）拉缸现象气缸拉伤后，在气缸壁上沿活塞运行的方向出现一条条深度不等的沟纹。同时，润滑油可能窜入燃烧室，排气管中有蓝黑烟排出，并造成燃烧室大量积炭。可燃气体漏入曲轴箱内，严重时润滑油加油口出现“喘气”现象，并窜出油烟。同时，机活塞有敲击声，机的功率不足。（2）拉缸原因1）活塞和气缸套配合间隙过小。2）活塞和气缸套之间润滑不良，严重时发生干摩擦。3）活塞环折断、咬死在活塞上。4）润滑油不清洁，含有大量杂质。5）大修后没有经过磨合直接长时间大负荷运转。动力设备（深圳）有限公司隶属于集团旗下蚌埠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蚌埠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，根据蚌埠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，请登录蚌埠干式变压器官网首页：
