摘要
介绍了南水北调中线工程河南安阳段液压启闭机系统的设备配置、特点和在现场的应用调试情况。该液压启闭系统左侧油路选用比例阀,右侧油路为开关阀,通过比例阀调节闸门启闭过程中的同步。将比例阀纠偏与开关阀纠偏的液压启闭系统进行比较,显示了比例阀控制的特点。
The configuration, the feature and the application commissioning of hydraulic hoist system at Middle Route Anyang section （in Henan province） in South-to-North Water Diversion Project is introduced. The hydraulic hoist system consists of a proportional valve at left oil-way and an on-off valve at right oil-way. The synchronous of the gate is regulated by the proportional valve. The comparison with the on-off valve synchronous system shows the characteristics of the proportional valve control.
