当已确定某缸或某一零部件工作运行不正常时，为了进一步判定故障的所在部位，可以进行对比检查，或将怀疑有故障的零部件，以本机其他缸的相同机件来代替，或者用备件更换的方法检查，如故障现象转移或消失，则证明该零部件有故障。例如：对刚起动不久的机，可用手触摸各缸排气口外壁，比较温度的高低，了解那一缸喷油过少，或查看有无不着火的气缸，可用手触摸喷油缸各缸的高压油管，从油管的膨胀脉动中，比较判断有无不供油的缸；还可在喷油泵的高压油管接头上，拆下一个有故障缸的和一个无故障缸的高压油管，然后起动机并使其怠速运转，通过观察、比较两油管接头处喷出的油注高度来进行判定。若有故障缸和无故障缸的油注高度一致，说明故障出在喷油器上或气缸的密封性差所造成；反之，说明故障出在喷油泵上。动力设备（深圳）有限公司隶属于集团旗下儋州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儋州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，根据儋州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，请登录儋州干式变压器官网首页：
