World's First Complete Set of 2000 kN Ultra-Large Thrust Reciprocating Compressor Successfully Developed!

English Official Translation (Petrochemical Heavy Equipment Standard Version)

The 4M200 ultra-large thrust reciprocating compressor unit, developed by the Reciprocating Compressor Division of Shengu Group for Fujian Fuhai Chuang Petrochemical Co., Ltd., has successfully passed mechanical running tests and acceptance under the joint witness of experts from the end owner Fuhai Chuang, PetroChina and Sinopec.

With an allowable integrated rod load of 2000 kN, this unit is the process reciprocating compressor with the world’s maximum allowable integrated rod load to date, as well as the world’s first delivered 2000 kN-class ultra-large thrust reciprocating compressor. Its successful development marks a major leap forward for China in the field of high-end reciprocating compressor equipment.

World-Leading Load Capacity & Multiple Breakthroughs in Core Technologies

The 4M200 unit not only achieves a milestone breakthrough in load-bearing capacity, but also integrates a host of original technological innovations:

One-Piece Cast Frame-Type Cylinder Body

It greatly improves frame rigidity and effectively restrains deformation, laying a stable foundation for ultra-large thrust operating conditions.

Vertically Split Tri-Metal Bearing Bush

It optimizes both load distribution and material performance, drastically boosting the bearing capacity and operational reliability of the bearing bush.

Integrated Barrel-Type Replaceable Crosshead Slideway

It enhances the overall rigidity and machining precision of the slideway, perfectly meeting the stringent requirements of large-scale reciprocating compressors.

Eccentrically Machined Crosshead Body

It optimizes the fitting degree of the friction pair between crosshead body and slideway to reduce friction and abrasion.

Piston Rod Elastic Fastening Structure Combining Precision Hydraulic Tensioning & Accurate Adjusting Rings

It realizes digital and precise control of the fatigue-resistant elastic fastening of piston rods, improving safety during long-cycle operation.

Integrated Intelligent Operation & Maintenance with Energy Conservation

Tailored to practical industrial site demands, the unit features in-depth innovations in maintainability, intelligent control and energy efficiency:

Top Opening Structure & Custom Special Tools

It tackles on-site installation and maintenance challenges of extra-large units and greatly reduces maintenance difficulty.

Intelligent Monitoring System & Modular Component Design

It enables real-time condition sensing of critical parts and elevates the overall intelligence of the unit.

Lightweight & Dimension Precision Optimization Technology

By adopting multiple optimization solutions, the unit’s efficiency is expected to rise by over 1% compared with conventional large reciprocating compressors, delivering remarkable energy-saving performance under high-power working conditions.

Broad Application Prospects & Support for National Energy & Chemical Strategies

This unit can be widely deployed in national key energy and chemical sectors including petrochemical, coal chemical, compressed air energy storage and hydrogen energy, especially applicable to:

Large petroleum refining installations

Large coal-to-liquid and coal-to-gas plants

Compressed air energy storage systems

High-pressure hydrogen storage and pipeline transportation

Furthermore, the series of innovative design and manufacturing technologies developed for the 4M200 unit will be gradually promoted to the R&D and production of reciprocating compressors across the whole industry. It will lift the overall technical level of China’s process reciprocating compressors, and carry great significance for securing independent controllability of energy equipment and advancing industrial upgrading.
