The miter gate hoist of the ship lock is the core component of the ship lock operation, and its opening and closing operation requires the gates on both sides to be synchronized and adapt to the external load changes caused by undercurrent, over-irrigation and over-discharge. A new type of pilot plug-in balance valve, designed for a 1:50 external load ratio, has been developed. We have constructed an AMESim model for the new pilot plug-in balance valve and hydraulic gate system, and conducted simulations to study its dynamic characteristics and anti-interference capabilities. The results indicate that the new type of pilot plug-in balance valve exhibits good dynamic performance. It can adapt to changes in external loads and is insensitive to them. The hydraulic hoist will not exhibit hydraulic cylinder crawling or herringbone gate drift under external loads.

摘要

The miter gate hoist of the ship lock is the core component of the ship lock operation, and its opening and closing operation requires the gates on both sides to be synchronized and adapt to the external load changes caused by undercurrent, over-irrigation and over-discharge. A new type of pilot plug-in balance valve, designed for a 1:50 external load ratio, has been developed. We have constructed an AMESim model for the new pilot plug-in balance valve and hydraulic gate system, and conducted simulations to study its dynamic characteristics and anti-interference capabilities. The results indicate that the new type of pilot plug-in balance valve exhibits good dynamic performance. It can adapt to changes in external loads and is insensitive to them. The hydraulic hoist will not exhibit hydraulic cylinder crawling or herringbone gate drift under external loads.
