reciprocating compressor for gas lift and offshore platforms

Our reciprocating compressors deliver high volumetric efficiency and a broad range of discharge pressures and volumes. With decades of design and manufacturing experience, we provide tailor-made solutions for diverse working conditions, ensuring stable and efficient operation even under harsh environments.

Working Principle of Reciprocating Compressor

The reciprocating compressor operates on the principle of volume change, using a piston’s reciprocating motion to intake and compress gas. The process includes:

1. Suction stage: The piston moves downward, cylinder pressure drops, the suction valve opens, and gas is drawn in.
2. Compression stage: The piston moves upward, reducing cylinder volume, compressing the gas, and increasing its pressure. When the set exhaust pressure is reached, the exhaust valve opens.
3. Exhaust stage: High-pressure gas exits the cylinder via the exhaust valve, entering the downstream system or storage. The piston returns to its initial position, ready for the next cycle.

This simple, stable process makes reciprocating compressors ideal for large flow and high-pressure gas applications.

Characteristics of Reciprocating Compressors

1. Large displacement & low speed design: Supports high gas flow needs; low speed reduces wear, improving durability and reliability.
2. High volumetric efficiency: Volumetric compression principle ensures efficient gas compression, maintaining high energy efficiency even at high pressure.
3. Multiple models & stages: Over 60 product series (M-type, D-type, L-type, P-type, etc.) and 1–6-stage compressors for all application scenarios.
4. API 618 compliance: Meets international standards, ensuring stability and safety, especially for oil and gas industries.
5. Customized services: Professional customization based on actual customer needs for specific environments and conditions.
