电容放电产生的强大电能,穿过适宜的液态介质时,会形成一种可控的应力冲击波,其传播速度极大,且有很大扰动。这种较强的压力脉冲可以有效地用于破碎较坚硬的岩石。本文介绍碎裂岩石的电水动力转换器及其试验细节。图1表示置于钻凿在混凝土块或坚硬岩石块中钻孔内的转换器。转换器将电能变成应力冲击波,它通过液体介质传播到孔壁和试块内部,造成试块的分裂或破碎。转换器的主要组件有发生器、传输装置和可控电能的利用装置。
The strong electric energy generated by the capacitor discharge, through the appropriate liquid medium, will form a controlled stress shock wave, the propagation speed of its great, and there is a great disturbance. This stronger pressure pulse can effectively be used to break harder rocks. This article describes the electro-hydrodynamic transducer for rock fragmentation and the experimental details. Figure 1 shows a transducer placed inside a borehole drilled in a block of concrete or hard rock. The converter turns the electrical energy into a stress shock wave, which propagates through the liquid medium to the walls of the hole and the test block, causing the test block to split or break. The main components of the converter generator, transmission and controllable power utilization device.
