宝应站清污机的优化设计和应用实践

Optimization design and application practice of the sewage cleaning machine at Baoying Station

宝应站作为南水北调东线一期工程第一级抽水站,自2005年建成以来发挥了抽水、排涝等功能。泵站地处里下河地区,水草量巨大,清污机长期高负荷运行导致故障。总结分析历年的改造维修和运行管理经验,结合现场实际情况,研究宝应站清污机整体强度、牵引力、功率、链条、齿耙结构、轨道、格栅、材质等方面优化设计方案。根据设计完成制造安装,通过在南水北调宝应站调水运行过程中实际应用,清污效果及运行稳定性均达到预期效果。

As the first stage pumping station of the first phase of the eastern route of south to north water diversion project,Baoying Station has played the functions of pumping and drainage since its completion in 2005.The pumping station is located in the Lixia River area,the amount of water grass is huge,and the long-term high load operation of the sewage cleaning machine has caused malfunctions.Summarize and analyze the experience of renovation,maintenance,and operation management over the years,combined with actual situation on site,research the optimization design plan for the overall strength,traction,power,chain,tooth rake structure,track,grid,material and other aspects of Baoying Station cleaning machine According to the design,the manufacturing and installation have been completed.Through practical application in the water transfer operation of Baoying Station in the south to north water diversion project,the cleaning effect and operation stability have achieved the expected results.
