多通道水压静力试验的破坏保护

The Local Destruction Protect of the Multi-channels Water Hydraulic Static Pressure Loading System

局部破坏保护是多通道水压静力加载系统的一个重要的系统保护, 也是保证静力试验安全、可靠进行的一个重要措施。本文提出了根据跟踪偏差来确定局部破坏的方法, 并介绍了一种解决截止阀开启后进行重新加载时, 载荷值超调过高问题的有效方法。

Protection of local destruction is very important in the multi-channels water hydraulic static pressure loading system.It is also one of the very important step to ensure experiment to run safely and reliably.One method which confirms local destruction based on the trace wind age was introduced,and one solution was introduced to prevent serious over shoot which happens as unlocked cut-off valve to be loaded again.
