Overview



This page showcases high-efficiency natural gas compressors manufactured by Bengbu United Compressor Manufacturing Co., Ltd., a leading China-based manufacturer specializing in gas compression solutions. The core products highlighted include the MW-17.4 / (0.1-0.2) -26 and MW-19.2 / (1-17)-(17-25) models, designed to meet diverse industrial needs for natural gas compression.


The MW-17.4 / (0.1-0.2) -26 Natural Gas High-efficiency Compressor stands out with its precise performance metrics: it handles a medium composition of 18% N₂ and 82% CH₄, boasting a processing capacity of 1000Nm³/h. Operating under an inlet pressure of 10~20KPa.G and inlet temperature of -20~40℃, it delivers an exhaust pressure of 2.6MPa.G, powered by a 200kW main motor. With overall dimensions of approximately 5200 × 3200 × 2000 mm and a weight of around 10T, it is engineered for stability in various settings.


Another key model, the MW-19.2 / (1-17)-(17-25) Natural Gas High-efficiency Compressor, offers a processing capacity of 19.2m³/min, operating with an inlet pressure range of 0.1~1.7MPa.G and inlet temperature of 40℃, while achieving an exhaust pressure of 1.7~25MPa.G. Equipped with a 400kW main motor, it features dimensions of roughly 8500 × 3200 × 2500 mm and a weight of 20T, making it suitable for large-scale industrial applications.


These compressors are widely utilized in urban gas pipeline systems to maintain stable supply pressure, household gas equipment (e.g., stoves and water heaters) as a CNG fuel source, CNG refueling stations for vehicle fuel supply, oil well injection to enhance crude oil recovery, and storage tank peak shaving to balance supply and demand during high-usage periods.


Features



High Efficiency and Reliability


Our natural gas compressors are designed for exceptional efficiency, reducing energy consumption while boosting operational productivity. Their robust reliability ensures continuous, stable operation under all specified conditions, minimizing downtime and keeping gas compression processes uninterrupted. With a high degree of automation, they integrate seamlessly into diverse systems, simplifying workflow management.


Easy Operation and Maintenance


Featuring fewer vulnerable parts, these compressors require less frequent replacement and repairs, lowering maintenance costs significantly. They operate with low vibration and noise, creating a more comfortable working environment. This stable performance also makes them user-friendly, even for operators with limited experience, ensuring smooth day-to-day use.


Convenient Transportation and Installation


All main and auxiliary equipment are mounted on a sled, ensuring reliable operation and simplifying transportation and installation. Whether shipped by sea, air, or land, the sled-mounted design saves time and effort during setup, making deployment efficient across different locations.


Precision-Engineered Components


The compressor body is crafted from HT250 casting, ensuring durability and a long service life. Both the cylinder and packing adopt oil-free structures, eliminating the need for oil lubrication and reducing contamination risks. Cylinder inlet and exhaust ports are arranged vertically (upward and downward) to prevent liquid hammer caused by internal liquid accumulation, enhancing operational safety. The air valve uses an internationally popular mesh structure with a stainless steel valve plate, further boosting performance and longevity.


Application Area


Natural gas compressors are used in oil and gas field development to increase gas well productivity, including natural gas transportation, oil and gas separation, wellhead pressurization, and other processes. For example, by using a compressor to boost and recover low-pressure associated gas, resource waste can be reduced. In addition, compressors are also used for gas well production and gathering in unconventional natural gas extraction such as shale gas and coalbed methane.

Natural gas compressor is the core equipment of long-distance pipelines, which ensures stable transportation of natural gas through multi-stage boosting. For example, compressor units are installed at the initial, intermediate, and final stations to compensate for pipeline pressure losses and achieve long-distance transportation.

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.
