深圳定西干式变压器油水分离器密封不严导致油路进空气

油水分离器密封不严导致油路进空气(l)故障现象 一台东风定西干式变压器组型，机正常起动后不久，出现自行熄火。(2)故障查找分析 检查油箱的油量，发现油箱中油位正常。打开低压油路中的放气螺塞，用手油泵供油，发现供油系统中有空气。排除空气后，机顺利起动，但工作运行不久，机又渐渐自动熄火，同时发现，燃油回油管三通接头处有泡沫状溢出。拆下接头紧固螺母后，发现接头内密封圈有裂纹，但更换此接头后起动机，故障现象仍然相同。再次打开弗列加滤清器上的放气螺塞时，有大量泡沫渗出，表明供油系统再次进了空气。仔细检查油箱至输油泵进油口处，用手油泵泵油时，发现油水分离器上的旋塞处有“滋滋”的漏气现象、拆除油水分离器上的旋塞检查，发现旋塞橡胶密封垫破裂。在日常维护中，由于油水分离器旋塞被反复拧动，造成密封垫损坏漏气，空气进入燃油系统，在油路中形成气阻，使喷油泵供油中断，机便自动熄火。(3)故障排除 更换损坏的油水分离器，排除供油系统的空气后，机工作运行正常。动力设备（深圳）有限公司，集团旗下专业运营定西干式变压器的销售业务及其售后服务，是中国区获得授权的定西干式变压器OEM成套厂家，长期与中字央企、大型房地产商、国际连锁酒店、著名建筑企业等单位建立战略合作伙伴关系。动力在中国布局五大定西干式变压器组生产基地，定西干式变压器售后服务点可辐射中国各省会及地级市区域。l定西干式变压器区分：移动式定西干式变压器、固定式定西干式变压器、超静音式定西干式变压器、机组载式定西干式变压器。l常见定西干式变压器功率（千瓦）范围：50KW至1000KW功率段。更多有关定西干式变压器的最新产品和技术内容，请登录定西干式变压器官网：http://www.11fdj.com定西干式变压器组的技术指标与其稳定性领先全球：高压注入(HPI)PT全权电子燃油系统。HPI G-Drive采用PT燃油系统由控制系统(GCS)控制器,这是提供off-engine安装定西干式变压器组的控制面板。量子控制一个特定的燃料系统板与HPI-PT燃油系统接口,提供了一个引擎保护包给大客户的灵活性和成本有效的替代控制设计和完整的权威electroni的好处。nCTT(涡轮增压技术)HX82 HX83涡轮增压利用排气能量与更高的效率改进的排放和燃料消耗。n低温冷却后,两泵双回线(2 p2l)。n黑色金属铸造球墨铸铁(FCD)活塞-高强度设计提供卓越的耐久性。nG-Drive集成设计,每个组件都有专门为G-Drive产品开发和严格的测试,确保高性能,耐久性和可靠性。n服务和支持——G-Drive以上信息由深圳动力官方发布，未经允许请勿转载！Cummins power equipment (shenzhen) co., LTD., corp., a professional operating cummins diesel generator sales and after-sales service, is China authorized OEM kit manufacturer of diesel generator, and for a long time in the state, large real estate developers, famous international hotel chain, construction enterprises and other units to establish strategic cooperative partnership.
