principle of operation
Carbon dioxide exists in liquid form below 3 1℃ or above 7.23MPa, but it begins to vaporize when it exceeds 3 1℃, and the pressure constantly changes with the change of temperature. According to the characteristics of carbon dioxide, liquid carbon dioxide is filled into the main pipe of the detonator, and the heating device is quickly stirred by the detonator. Liquid carbon dioxide instantly gasifies and contracts to generate high pressure, and its volume is reduced by more than 600 times. When the pressure reaches the ultimate strength (settable pressure) of the bursting disc, the constant pressure shear disc ruptures, and high-pressure gas is released from the relief head to act on the medium (rock), thus achieving the purpose of blasting. The fracturing device adopts the existing connecting rod, which can complete multi-point simultaneous directional blasting to break rocks.
