The CNG refueling sub-station is built in the place where the gas pipeline network has not yet reached, and receives the compressed natural gas transported by the semi-trailer from the refueling mother station, and refuels the car through the gas vending machine after storage, compression and other processes.

The main equipment of the CNG refueling sub-station is composed of a compressor unit, a metering device, a gas unloading treatment, a gas storage device, a charging sequence control panel, and a gas vending machine.

The natural gas bottle filling compressor developed by our company is carefully designed with advanced and reliable parts and advanced design methods. The main components (piston ring, valve, etc.) adopt the world brand HOERBIGER products, which have high efficiency, strong reliability, high degree of automation, long wearing parts, low vibration, low noise, convenient operation and maintenance, etc. Features. The product is mainly used in natural gas compressors for refueling mother stations and sub-stations. The air supply volume ranges from 300Nm3/h to 1000Nm3/h, and the power ranges from 22 to 75KW. The overall structure can be fixed, skid-mounted, or sound-proof cubicle type.

Introduction of Compressor of Natural Gas Substation

The natural gas compressor used in the CNG substation is the basic component of the product manufactured by our company introduced the German MANNESMANN DEMAG (Mannesmann Demag) company technology and obtained the company’s production license as the basic component of the product; to ensure low Noise requirements, equipped with noise reduction box; in order to ensure the quality of gas transmission, equipped with a degreasing filter at the air supply port; in order to reduce the impact of the starting load on the power grid in the station, a soft starter is used to control the starting current; in order to realize the fully automatic control function, This machine uses PLC to control the pneumatic ball valve, which is driven by air, which is more reliable.

It is mainly composed of noise reduction box, compressor chassis, compressor mainframe, electric motor, separator, lubricating oil circuit system, gas pipeline system, cooler system, instrument control system, auxiliary and automatic control system, etc. Therefore, the machine has the characteristics of low energy consumption, low noise, low vibration, high reliability all-weather, high degree of automation, and convenient operation and maintenance.
