摘要
实验的目的是探究水系的体积变化对煤层高压脉动水锤注水装置工作时产生的峰值压力的影响;通过实验发现随着水系体积的增加,压力波在管路中传播的时间延长;从高压缸出口到管路末端的压力衰减程度增大;高压缸出口处压力波峰值压力减小。
The purpose of the experiment is to investigate the change of water volume impact on the peak pressure of water hammer pressure wave. Experimental results show that with the increase of water volume,the time of pressure wave propagation in the whole line get longer. When pressure wave export to the end of the line from high pressure cylinder,the degree of pressure attenuation increase. The peak pressure of the high pressure cylinder outlet decrease.
