reciprocating compressor for gas injection and extraction

The operating principle of our reciprocating compressors is based on the reciprocating motion of a piston, enabling efficient gas compression through volume changes. With a wide range of discharge pressures and volumes, as well as high volumetric efficiency, these compressors are essential for heavy industries and specialized gas treatment processes. We provide fully customized solutions to meet the individual needs of our customers, ensuring optimal adaptation to site conditions and operating requirements.

Principle of Operation

Gas is compressed by the reciprocating motion of a piston inside a cylinder, typically in three main stages:

1. Suction stage: The piston moves downward, lowering cylinder pressure below atmospheric, opening the suction valve and drawing gas into the cylinder.
2. Compression stage: The piston moves upward, reducing cylinder volume and compressing the gas. As pressure rises to the set value, the exhaust valve opens.
3. Exhaust stage: The compressed high-pressure gas is discharged through the exhaust valve into downstream systems or storage devices. The cycle then repeats.

Reciprocating Compressor Characteristics

1. Wide range of discharge pressures and volumes: Suitable for a variety of gas compression needs, from low to high pressure and small to large volumes.
