CNG Daughter Station Compressor

Application of compressor in substation

The sub station is built in areas where there are no natural gas pipelines passing through. Natural gas is transported from the main station to the sub station by CNG trailers, and then directly filled into CNG vehicles or stored in fixed gas cylinder groups through unloading columns and compressors.

Compressor Performance Description

Using technology from our Austrian and German companies to ensure high reliability of our products

Key components such as air valves and piston rings are sourced from Austrian technology, with a service life of over 8000 hours

The soft start function allows frequent starting and stopping of the compressor

Wide intake range, suitable for a wide range of applications

The overall assembly structure has low noise levels and is cost-effective to install in urban areas

Using Siemens PLC control system to achieve high automation

Structure Introduction

Compressors are reciprocating compressors, which can be divided into two types: those with foundations or those without foundations. The whole machine is mainly composed of fixed parts and moving parts. Fixed components include the body, middle body, cylinder head, cylinder, and cylinder seat. The moving parts include crankshaft, connecting rod, crosshead, piston, air valve, and are equipped with pipeline and instrument control system

Cooling method

1. Water cooling

2. Air cooling

3. Mixed cooling (choose according to actual needs)

Overall structural form

Fixed and soundproof cabin (choose according to actual needs)

Performance Description for Both Compressor Types

Vulnerable components such as gas valves and piston rings are sourced from the Austria company, with a service life of over 8,000 hours.

Soft start feature allows frequent compressor starts and stops.

Wide range of air intake, suitable for a broad range of applications.

The overall assembly structure results in low noise levels and is cost-effective for installation in urban areas.

Utilizes Siemens PLC control system for high automation.

Parameters for Natural Gas Transmission Compressors

1. Vertical: Displacement ≤ 3m3/min, Pressure 0.02MPa~4Mpa (Selected based on actual requirements)

2. Symmetrical: Displacement ≤ 10m3/min, Pressure 0.2MPa~2.4Mpa (Selected based on actual requirements)

3. V-Type: Displacement ranges from 0.2m3/min to 40m3/min. Discharge pressure ranges from 0.2MPa to 25MPa (Selected based on actual requirements)

Compressor Usage for CNG Stations

Receives natural gas through pipelines, pressurizes it within the station, and directly fills compressed natural gas into CNG vehicles or stores it in fixed gas bottle banks (wells).
