拆装错误也是引起机故障的重要原因之一。其中有以下几个方面：1）活塞环安装位置不正确。活塞环开口位置未错开，扭曲环上下面倒装等，将引起窜机油现象和窜气现象。2）喷油器垫片安装不正确。喷油器中喷油嘴伸出气缸盖底平面高度有严格的尺寸要求，若因垫片漏装或多装而使该尺寸过大或过小，将引起燃烧恶化、积炭严重、功率不足、冒黑烟、或因漏装垫片造成从喷油器处漏气、烧坏气缸盖等现象。3）气缸垫安装不正确。气缸垫选用不当或者漏装，将造成气缸压力下降、漏气和活塞碰气缸盖等故障。4）齿轮啮合不正确。齿轮啮合记号装错，将导致气门碰活塞，供油提前角太大或太小，引起燃烧恶化、冒黑烟、排气温度升高或者活塞烧损等故障。5）螺母安装不正确。紧固连杆螺母、气缸盖螺母时，力矩不准或紧固顺序不对，将造成气缸盖密封不严，甚至螺栓断裂等故障。6）有关配合间隙超差。当活塞和缸套配合间隙、轴和轴承间隙、齿轮啮合间隙等不符合要求时，将造成异常磨损、拉缸、烧瓦和齿轮损坏等故障。动力设备（深圳）有限公司隶属于集团旗下济宁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济宁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，根据济宁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，请登录济宁干式变压器官网首页：
