摘　　要：双吊点液压启闭机在大中型闸门的启闭上应用广泛,针对其液压同步系统进行分析。分析了双吊点液压启闭机双缸同步误差形成的原因;介绍了双缸同步闭环控制方案;结合闸门双吊点液压启闭机液压同步控制的工程实际,分析了目前典型同步回路的工作原理及特点;最后归纳了双吊点液压启闭机同步回路的发展趋势。Two-lifting-point hydraulic sluicegate hoist has come to be widely used in large-or medium-sized sluiccgatas. The paper analyzes the causes of non-synchronous moving of the two cylinders from the two lifting-point hydraulic hoist, introduces the double closed loop control method for the two cylinders＇ synchronous moving, describes the working principle and technical characteristics of the current classical synchronous circuits combining with the practical project, and points out the trend of synchronous technologies in sluicegate hoists.
