High-speed, high-precision, and ultra-high pressure pneumatic control technology can be applied in technical fields such as construction machinery, hydrogen energy vehicles, and aerospace. Core basic components (components) have been listed as one of the key breakthrough bottlenecks in the 'Made in China 2025' industrial foundation project. Gas nonlinearity, pneumatic compression and release, and asymmetric heat transfer and absorption, as well as intermolecular forces between ultra-high pressure gas molecules, are world-class fundamental problems. The 'bottleneck' key core technologies for high-speed, high-precision, and ultra-high pressure pneumatic control high-end devices severely restrict the development and application in cutting-edge areas. With continuous support from projects such as the National 863 Program, National Natural Science Foundation, and National Science and Technology Support Plan, after nearly twenty years of focused research and original innovation, significant progress has been made in high-speed and high-precision pneumatic control methods, ultra-high pressure components, Breakthroughs have been made in recognized bottleneck technologies in major equipment fields, breaking foreign control and blockades. This has achieved a technological leap for high-speed and high-pressure pneumatic core components in China, filling domestic gaps. The main technical inventions are: (1) In response to the long-standing key issues of low speed and nonlinearity that have plagued pneumatic systems, based on the invented high-speed and high-precision pneumatic control method, a large-diameter pneumatic downhole hammer with a sleeve drill was invented. This is the first time that a dual-channel downhole hammer has been proposed and realized, which achieves simultaneous grouting and gas injection through the developed dual-channel rotary joint, and provides damping and buffering for the upper power head. A systematic research and design method for a dual-channel large-diameter pneumatic downhole hammer with helical slag discharge blades has been formed. (2) In response to the international challenges of ultra-high pressure pneumatic control valves and their systems, The 70MPa and 35MPa ultra-high pressure grading pressure control methods were proposed, the conical valve core cylindrical slide valve was invented, advanced and applicable vehicle-mounted ultra-high pressure control valves that meet or exceed the level of foreign similar products were independently developed, dynamic and static compensation for gas resistance, gas capacity pressure and flow fluctuation as well as asymmetric control methods were invented, achieving rapid charging and discharging in extreme low temperatures (-40°C) and extremely high temperatures (+60°C) during hydrogen transportation and hydrogen addition processes, as well as ultra-high pressure stable control during driving. (3) A pneumatic hydraulic compound pile hammer system using acceleration technology was invented, which achieves quick lifting of the hammer body through the hydraulic system, utilizing the combined effect of compressed gas energy and the inertia mass of the hammering components to strike the foundation piles, realizing a piling process with an acceleration of more than 2g for the hammer body. A new type of pneumatic-hydraulic hybrid cylinder system was invented. The basic parameters of nitrogen chambers and accumulators, as well as the methods for adjusting impact energy, have been proposed. (4) The mechanisms behind severe nonlinearity in gas resistance and serious asymmetry in the gas-resistance-gas volume system have been elucidated. In addition to software compensation, a high-speed pneumatic control method that matches pneumatic components with gas volumes has been proposed and invented. The mechanism of pneumatic refrigeration and heating based on the intermolecular attraction and repulsion of ultra-high pressure gases has been explained. The inventions have been verified and played an important role in the development of aircraft attitude control, pneumatic thrusters, and multi-cycle high-speed pneumatic percussion hammers. These series of pneumatic inventions have obtained 9 authorized invention patents, 3 authorized utility model patents, applied for 3 invention patents, compiled 2 industry standards, published 1 Chinese monograph and 1 English monograph, won the First Prize for Excellent Science and Technology Books, published 52 papers in total, including 33 domestic papers and 19 foreign papers, with 8 papers being included in SCI/EI. The invention has been cited a total of 149 times by others domestically and internationally. The core achievement, the pneumatic down-the-hole hammer, has been applied in pile foundation construction for complex strata, generating an additional direct economic benefit of 208.4 million yuan in the past three years. The core achievement, the ultra-high pressure pneumatic control valve, has been used in 863 special topic projects, with 16 prototype sets developed for demonstration applications of new energy vehicles. The invention's core technology, pneumatic hydraulic composite control, has been used in the development of high-end pneumatic hydraulic hammers and the construction of deep-sea wind power foundation platforms. The project outcomes have significant social and economic benefits.
