Product introduction
The carbon dioxide expansion power system uses the principle that liquid carbon dioxide absorbs heat, vaporizes, expands, and the pressure rises rapidly. After reaching the target pressure, it instantly releases high-pressure gas to break and loosen rocks. The expansion tube is small in size, easy to transport, safe and reliable in use, and has controllable power. It can be widely used in coal mines, non-coal mines, underwater, urban municipal construction and other fields, creating a new situation in my country's green energy mining operations!
Working principle
Fill the wave storage tube of the carbon dioxide rupture ring with liquid carbon dioxide, and start the heating device to generate a large amount of heat, causing the liquid carbon dioxide in the storage tube to instantly vaporize. The volume expands about 600 times, and the pressure rises sharply. When the pressure in the camp reaches constant pressure shear When the sheet reaches its ultimate strength, the high-pressure gas breaks through the constant-pressure shear sheet and is released from the energy discharge head. The powerful thrust generated instantly is used to break through the material along the natural fissures of the coal and rock mass, thereby achieving the purpose of ultra-high-pressure rock breaking and mining.
The constant pressure shearing disc is a component that controls the energy release pressure. Different release pressures can be controlled by replacing shearing discs with different specifications. The current maximum release pressure can reach 800MPa.

Technical advantages
(1) Advanced design concept, using the principle of endothermic expansion, vaporization and pressure increase between liquefied gases for design and manufacture. The action process of the cracker is a physical endothermic process, which is different from the chemical explosion of explosives and does not produce harmful gases such as carbon monoxide. , will not produce an open flame, eliminating the possibility of igniting coal and gas; at the same time, it can be used in complex environments;
(2) The storage pipe is made of imported special steel and can withstand a pressure of more than 800MPa, which is much higher than the relief pressure in normal use, ensuring that there will be no safety hazards due to damage to the pipe body during use;
(3) The heating device will not be activated under normal temperature and pressure, and is safe for storage and transportation. It can only be activated in the internal environment of the cracker. (4) The cracking power is huge, and the rate of cracking coal and rock into blocks is high, which avoids dust occurs, and the precise positioning of the pre-crack position can be achieved
(5) It is not restricted by civil explosive products and can be constructed at any time; it avoids the problems of approval, storage and transportation, blind guns, dumb guns, etc. that exist with explosives; (6) The economic cost is lower than that of explosives, and the liquid storage pipe can be reused and has a service life of up to For 10 years, the cost has been effectively reduced; (7) The power is controllable and can be used in environments where traditional explosives cannot be used; it can be used at close range in buildings and environments with a large flow of people.
use:
(8) It will not generate seismic shock waves, the vibration speed is small, and it will not cause structural damage to the foundation;
(9) The connection is convenient, fast and stable. The entire system is independently developed and produced by our company. It can be upgraded and replaced with pre-sales and after-sales services.
