The DWFD-2.8 (1.28)/(2-10)-55 Natural Gas High-efficiency Compressor is a premium product manufactured by Bengbu United Compressor, a leading China-based provider of industrial compressors. Designed for natural gas processing, this compressor stands out for its high efficiency, robust performance, and versatile applications in energy transportation and industrial operations.
Tailored to handle natural gas as its primary medium, the compressor boasts a processing capacity of 10000~18000Nm³/d, making it suitable for both large-scale and medium-scale operations. It operates with an inlet pressure range of 0.2-1.0MPa.G and an inlet temperature of ≤40℃, delivering an exhaust pressure of 5.5MPa.G—ideal for meeting the demands of long-distance gas transportation and industrial gas management. Powered by a 90kW main motor, the unit features compact dimensions (approximately 6500 × 2800 × 2700 mm) and a weight of around 10.5T, ensuring easy integration into existing systems.
The DWFD-2.8 compressor adopts a D-type symmetrical balanced structure, combined with air cooling, oil-free lubrication, and reciprocating piston technology. This design enables two-stage to three-stage compression with double-acting functionality, ensuring stable and efficient gas compression. The entire unit is supplied as a skid-mounted system, which simplifies installation and reduces on-site setup time— a key advantage for projects requiring quick deployment.
Equipped with an explosion-proof control cabinet featuring soft start technology, the compressor integrates a Siemens Smart-200 PLC and a 10-inch touchscreen display, with an RS485 communication interface for seamless connectivity. This setup enables unmanned operation, remote monitoring of operational data, and real-time alarm notifications. Safety is prioritized through built-in protections against motor overload, short circuits, and abnormal fluctuations in oil pressure, intake/exhaust pressure, and exhaust/oil temperature—ensuring reliable operation even in harsh environments.
Designed with minimal vulnerable parts, the compressor reduces maintenance frequency and costs. Its low vibration and noise levels enhance workplace safety and comfort, while the skid-mounted integration of main and auxiliary equipment ensures smooth, reliable operation. The unit’s components are precision-engineered, backed by four patents (including piston rod thread protective sleeves and piston ring support devices), further validating its durability and technical excellence.
This compressor serves as a core asset in multiple scenarios:
· Long-distance pipelines: Installed at initial, intermediate, and final stations to compensate for pressure losses, enabling efficient natural gas transportation.
· Oilfield injection: Injects natural gas into oil wells to boost crude oil recovery rates.
· Storage peak shaving: Balances supply and demand during periods of high gas consumption, ensuring stable energy access.

Whole Machine Description
The compressor adopts D-type (symmetrical balance type), water-cooled, oil-free lubrication, reciprocating piston type, 2-row 3-stage compression, and the entire unit is supplied in a modular manner.
The compressor crankcase is made of gray cast iron and has four holes of different diameters for installing crosshead slides, bearings, and bearing seats. The lower part of the crankcase can store lubricating oil for the compressor to lubricate; The upper surface of the crankcase has an interface for installing a fuel inlet (breathing port) cover plate; In addition, the crankcase also has spare interfaces such as oil drain port, oil gauge observation port, bearing seat oil injection port, and installation oil temperature measurement port. The oil drain port of the crankcase has been connected to the outside of the compartment and is equipped with a manual ball valve for oil discharge from the crankcase.
The middle body of the compressor is a double middle body structure, ensuring that the middle body space is greater than one stroke, preventing compressor oil from entering the cylinder from the crankcase, thus ensuring that compressor oil does not contaminate the medium. The material of the compressor cylinder is gray cast iron/forged steel, and it adopts an oil-free lubrication design, which does not require oil lubrication. The cylinder head material is gray cast iron/forged steel, and the air valves are arranged axially on the cylinder head.
