摘要
针对朱家店煤矿矿井水排放关阀停泵时管路振动剧烈,水锤现象严重的问题。文章设计了基于冲击压力、管道振动、流速大小信号的反馈式阀控防水锤系统,通过控制阀的关闭速度和运动轨迹来消减水锤,并通过大量实验选取最佳关阀策略,与未采用任何控制方法的普通电动阀门和相同关阀时间内不同控制策略下管道冲击压力进行对比。实验结果表明该方法可有效防护水锤,较其他方法产生更小的冲击压力,能更有效缓解水锤现象。
Aiming at the serious water hammer phenomenon when the gate valve is closed in Zhujiadian Coal Mine drainage system,a feedback valve-control waterproof hammer system is designed based on the shock pressure,the vibration of pipeline and the signal of velocity,controlling the speed of shutoff valve to reduce the water hammer. A large number of experiments are carried out to select the best shutoff valve speed,compared with the impact pressure of pipeline when no control method is adopted or under different control strategies in the same time of closing valve. The experimental results show that the method can effectively protect water hammer and produce less impact pressure than other methods.
