Recently, the 4M200 ultra-high thrust reciprocating compressor unit developed by SHENGU Group’s Reciprocating Machine Company for Fujian Fuhai Chuang Petrochemical Co., Ltd. successfully completed its mechanical operation tests and acceptance procedures, in the presence of representatives from Fuhai Chuang’s ultimate owner, as well as experts from CNPC and SINOPEC. The allowable comprehensive rod load of this compressor unit reaches 2000 kN, making it the reciprocating compression unit in the world with the highest allowable comprehensive rod load to date. It is also the world’s first 2000 kN-class ultra-high thrust reciprocating compressor to be developed and delivered, marking a significant breakthrough for China in the field of high-end reciprocating compressor equipment. It leads the world in terms of load-bearing capacity, with multiple core technologies achieving breakthroughs. The 4M200 unit not only delivers a milestone-level improvement in load-bearing capacity but also incorporates a range of original technological innovations: 1. An integrally cast frame-type airframe that significantly enhances the airframe’s stiffness, helps to control deformation effectively, and provides a stable foundation for operations under high thrust conditions. 2 Vertically splitting the three-alloy bearing shells enables dual optimization based on load distribution and material properties, thereby significantly enhancing the bearing shells’ load-bearing capacity and reliability. 3 Overall tubular replaceable crosshead slideway: It enhances the overall stiffness and manufacturing precision of the slideway, enabling better compliance with the stringent requirements of large reciprocating compressors. 4 Eccentric processing of the crosshead body: Optimizes the fit between the crosshead body and the sliding surface, thereby reducing friction and wear. 5 A piston rod elastic fastening structure combining precise hydraulic stretching with an accurate adjustment ring improves the numerical accuracy and precision of the elastic fastening to resist fatigue, thereby enhancing safety during long-term operation. b3f2f0bf-b547-4f85-8901-e6987a464c64.jpg Emphasizing both intelligent operation and maintenance as well as energy savings, the units have undergone significant innovations in terms of ease of operation and maintenance, intelligence, and energy efficiency, to meet the actual needs of industrial environments: 1. A top-opening design along with specialized tools are used to address the challenges associated with the installation and maintenance of ultra-large units, thereby greatly reducing the difficulty of maintenance. 2 Intelligent monitoring system + modular component design enables real-time detection of the status of key components, thereby enhancing the overall intelligence level of the unit. 3 Lightweighting and precision sizing technologies: By integrating various optimization methods, it is expected to achieve a efficiency improvement of over 1% compared to traditional large reciprocating machines, offering significant energy savings in high-power applications. c87faef4-b323-4c5e-9a06-a8b79044a3ac.jpg It has broad application prospects and supports the **energy and chemical industry strategy**. This unit can be widely used in key areas of the energy and chemical sector such as petrochemicals, coal chemistry, energy storage, and hydrogen energy; it is particularly suitable for large-scale oil refining facilities ； Large-scale coal-to-oil and coal-to-gas plants ； Compressed air energy storage system ； High-pressure storage and pipeline transportation of hydrogen. Furthermore, the range of innovative design and manufacturing technologies developed for the 4M200 unit will be gradually applied to the research, development, and production of reciprocating compressors in this industry, thereby helping to raise the overall technical level of such compressors in China. This is of great significance for ensuring self-sufficiency and control over energy-related equipment as well as for promoting industrial upgrading.
