一、情况概述某煤矿用的一个空气压缩机站,产生的压缩空气供井下采煤和掘进岩石巷道之用。此空压机站原来设在井口,运转比较平稳,管道系统也没有明显的振动。后来由于生产上的需要,空气压缩机站搬了一次家,管道配置也作了改变。但从此就发生了强烈的管道振功。不仅手摸到管道上要被弹回来,而且人站在储气罐旁也觉得晃动,有不安全的感觉。同时,由于冷却水的水质不好,水垢过多,冷却效果不好,造成排气温度过高(>170℃)。终于在七四年的一个深夜,发生了5号储气罐爆炸事件,碎片飞出数百米之外。事故发生之后,采取了很多措施:对支承作了加固,在管壁附近加了限位器,在排气管内加限温器,以便当振
First, the situation outlined An air compressor station used in a coal mine, resulting in compressed air for underground coal mining and tunneling tunnel purposes. This air compressor station was originally located in the wellhead, the operation is relatively stable, the pipeline system is also no significant vibration. Later, due to the needs of production, the air compressor station moved home once again, and the piping configuration was changed. But since then there has been a strong pipeline vibration. Not only hand touch the pipe to be bounced back, but also people standing beside the gas tank also feel shaking, there is insecurity. At the same time, due to the poor quality of cooling water, excessive scale, the cooling effect is not good, causing the exhaust temperature is too high (> 170 ℃). Finally, in the middle of the night of 1974, an explosion occurred on the 5th gas tank and the debris flew hundreds of meters away. After the accident, many measures were taken: strengthening the support, adding a stopper near the pipe wall, adding a temperature limiter in the exhaust pipe, so that when the vibration
