Embodiment Construction

[0027] refer to Figure 1 ~ Figure 4 , the present invention is a kind of transmission technology of supercritical carbon dioxide, comprises the following steps:

[0028] 1) A supercritical carbon dioxide flow regulating device 2 is arranged between the supercritical carbon dioxide generating device 1 and the supercritical carbon dioxide output device 3, and the transfer pipeline 22 in the supercritical carbon dioxide flow regulating device 2 is replaced until it meets the output requirement, mainly By switching the length of the transfer pipeline 22, to change its flow rate;

[0029] 2) generate supercritical carbon dioxide by supercritical carbon dioxide generating device 1, and supercritical carbon dioxide flows into the output pipeline 31 of supercritical carbon dioxide output device 3 through supercritical carbon dioxide flow regulating device 2;

[0030] 3) An auxiliary gas flow pipeline 32 is provided outside the output pipeline 31 of the supercritical carbon dioxide o...

Abstract

The invention discloses a transmission process of supercritical carbon dioxide, comprising setting a supercritical carbon dioxide flow regulating device between a supercritical carbon dioxide generating device and a supercritical carbon dioxide output device, and replacing the transfer pipeline in the supercritical carbon dioxide flow regulating device to It meets the output requirements; an auxiliary gas flow pipeline is installed outside the output pipeline of the supercritical carbon dioxide output device, and heated auxiliary gas is continuously injected into the auxiliary gas flow pipeline. Outside the carbon dioxide output pipe, it plays the role of temperature compensation, ensuring the stability of the supercritical carbon dioxide fluid and the performance of the supercritical carbon dioxide. This invention is used in the field of metal processing.

Description

technical field [0001] The invention relates to the field of metal processing, in particular to a transmission process of supercritical carbon dioxide. Background technique [0002] With the rapid development of modern advanced manufacturing technology, various new materials and new processes have emerged, which put forward higher requirements for cutting speed, tool life and processing efficiency of machine tools. Clean production and green manufacturing have become one of the themes in the development of advanced manufacturing technology. The low-temperature cooling and lubricating cutting technology has been proved to be an effective solution to solve the difficult-to-machine characteristics such as strong cutting thermal shock and vibration of high-hardness and high-strength materials, and plastic materials are easy to produce processing burrs. [0003] At present, the commonly used low-temperature cutting technologies are mainly: low-temperature cold air (-30°C) coolin...
