喷射压力
Finally, the analysis of the specimen sections demonstrates that hydraulic sandblasting perforation can generate cracks on the specimens. The influence of rock characteristics and jet pressure on the cracks is also obtained.
最后对射孔后的试件进行了切片,证明了水力喷砂射孔可以在岩石上产生裂纹,并获得了不同岩性、不同射孔压力在试件上产生裂纹的规律。
Established indoor has simulated the test platform, the test result indicated that enhanced the revolving jet flow to break ground the effect to increase the jet flow power, and enhanced the jet pressure to the effect enhancement which broke ground is very obvious.
建立了模拟试验系统,试验结果表明,提高旋转射流破土效果必须增大射流功率,提高射流压力对破土的效果提高是很明显的。
