【摘要】 针对大型水闸工程——江苏省江都水利工程管理处金湾闸22台套双节顶升式液压启闭机,从结构型式、运行方式、运行问题与检修工艺进行阐述。重点说明了伸缩式单作用柱塞缸这种特殊结构型式的液压启闭机在长期运行中出现的泄漏、速度下降、爬行、杆件拉伤等问题,详细介绍了维修方法与流程、检测内容数据、调试及试运行要求。特别是采用了几种非常规维修工艺:进油孔油槽改造、利用测压接头改装排气旋塞、镀铬工艺进行技术改进,提供了故障排除方法实例。更多还原

【Abstract】 Aiming at the large-scale sluice project-Jinwan Sluice of Jiangdu Water Conservancy Project Management Office in Jiangsu Province,22 sets of double-section jacking-up hydraulic hoists were described from the structure type,operation mode,operation problems and overhaul technology. The problems such as leakage,speed drop,crawling,rod pull and so on in the long-term operation of the special structure of the telescopic single acting plunger cylinder hydraulic hoist were emphasized. The maintenance method and process,test content data,commissioning and trial operation requirements were introduced in detail. In particular,several unconventional maintenance processes such as the modification of the oil inlet groove,the modification of the exhaust cock using the pressure measuring joint,and the technical improvement of the chrome plating process were used to provide examples of troubleshooting methods.更多还原
