1results about How to "Wide working pressure range" patented technology

This invention belongs to the field of high-pressure fluid jet control technology, and particularly relates to a pressure stabilizing device and jetting method based on supercritical carbon dioxide high-pressure jet. It includes a carbon dioxide storage cylinder, a cold bath connected to the outlet of the carbon dioxide storage cylinder, a cold bath outlet connected to a liquid carbon dioxide storage tank, a storage tank outlet connected to a booster pump inlet, a booster pump outlet connected to a hot bath, and a hot bath outlet connected to a jet pressure stabilizer. One end of the jet pressure stabilizer has a nitrogen inlet pipeline, and the other end has a high-pressure supercritical carbon dioxide outlet pipeline. The high-pressure supercritical carbon dioxide outlet pipeline is connected to the jetting system. The jetting system also includes an impact force characteristic testing component. This invention solves the problems of low operating efficiency, poor cutting effect, and difficulty in accurately controlling the fluid jetting process caused by fluid pressure fluctuations and sudden drops in engineering. This pressure stabilization method is simple, easy to implement, and convenient to control, and has broad application prospects.
