1.气缸盖裂纹检查一般来说,在气缸体平面,气门导管孔、喷油器孔、冷却水套壁等处易产生裂纹。可用水压试验、气压试验和磁力探伤等方法进行检查。2.缸盖平直度检查气缸盖与气缸垫配合表面如有伤痕、腐蚀或不均匀磨损时,应进行检查。平面度用直尺合塞尺检查。气缸套每次加工量为0.1270~0.1524mm,气缸盖厚度加工达到使用极限时应予以报废。6BT系列机气缸盖的厚度最小为111.00mm,最大为111.25mm,磨损极限为110.24mm。应当注意气缸盖平面未重新加工时,只允许用0.7939mm的缸垫。KTTA型机气缸盖厚度X不小于119.76mm。气缸盖的上平面和下平面必须是平行的,不平行度在0.13mm以内,否则可能使气缸套座孔发生变形。如果在气压试验或水压试验中发现喷油器套有渗漏或损伤,则应更换喷油器套。1)用专用拉器卸下喷油器套筒。2)用钢丝刷清除喷油器套筒密封面上的杂质。3)气缸盖与喷油器套之间接触座面的边缘如有磨损,可用铰刀来铰关表面,切削深度不大于0.254mm。3.喷油器套筒的安装1)在新的喷油器套O形圈上涂上一层清洁的机油,将它装到缸盖的O形圈槽中。2)用专用工具将喷油器套压入气缸盖孔中,并用压紧工具压紧,用扩张器扩张喷油器套上部和底部,使它和气缸盖之间密封。3)用喷油器座面铰刀铰削喷油器套的座面。将喷油器装入气缸盖,用14~16N·m的力拧紧螺栓,安装喷油器压板,再用千分表测量气缸盖底平面与喷油器顶端的距离即为突出量。6BT行机喷油端部的突出量为1.52~1.78mm。如突出量不够可铰削喷油器套座面。4)在喷油器套座面上涂以蓝油,装上喷油器,按规定力矩紧,再取下喷油器,观察座面的接触情况,其油的痕迹应为光整的一圈,最小宽度为1.52mm,如果接触面宽度不符合要求,则应更换喷油器套,或用一锥行刷子清理喷油器座孔,在此检查密封带的痕迹,如果密封仍不在规定范围内,气缸盖就必须予以更换或修理。动力设备(深圳)有限公司隶属于集团旗下河池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河池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,根据河池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,请登录河池干式变压器官网首页:
