Knowledge about Chongqing Chuangpuda Machinery Technology's carbon dioxide fracturing equipment

　　Carbon dioxide exists as a liquid below 31 degrees Celsius or at pressures above 7.35 MPa, but begins to vaporize above 31 degrees Celsius, and the pressure changes continuously with temperature. Utilizing this characteristic, liquid carbon dioxide is filled into the main pipe of the fracturing device. A rapid firing heating device is used to instantly vaporize and expand the liquid carbon dioxide, generating high pressure with a volume expansion of more than 600-800 times. When the pressure reaches its ultimate strength, the high-pressure gas bursts and acts on the rock mass and ore body, achieving the purpose of expansion fracturing. This overcomes the disadvantages of previous blasting and pre-splitting methods, such as high destructiveness and danger, providing a reliable guarantee for the safe mining and pre-splitting of mines and rocks. It can be widely used in many industries such as mining, cement, and quarrying. At the same time, the carbon dioxide gas rapidly released during the fracturing process of the carbon dioxide fracturing device has a cooling effect, and carbon dioxide is an inert gas, which can completely avoid accidents caused by open flames from blasting.

　　The second-generation carbon dioxide fracturing device is a new type of fracturing equipment independently developed by our company. It mainly consists of a filling machine, a storage tank, and a fracturing device. Compared with the first-generation carbon dioxide fracturing equipment, our company's products save more manpower, materials, and costs.
