摘要
大中型水利工程中,闸门的作用举足轻重。跨度较大的闸门启闭一般采用双缸液压启闭机,实践证明双缸液压启闭机最重要的是保证两缸同步性,两液压缸的同步性是由自动纠偏系统来完成的。自动纠偏系统主要由闸门行程检测装置、PLC纠偏控制程序、电气控制回路及液压纠偏回路组成。
The gate plays a critical role in large and medium-sized water conservancy projects.Gate with large span is opened and closed generally by dual-cylinder hydraulic hoist.Practice shows that it is important for dual-cylinder hydraulic hoist to guarantee the synchronization of two cylinders.Synchronization of two hydraulic cylinders is completed by automatic correction system.Automatic correction system mainly consists of gate stroke detection device,PLC correction control procedure,electrical control circuit and hydraulic correction loop.
