piston compressor for gas-fired power generation

Due to their high reliability and ability to operate in harsh environments, piston compressors occupy an important position in many applications requiring high-pressure gas transportation, storage, and pressurization. Our company provides customized compressor solutions tailored to the actual needs of each customer, ensuring optimal performance under specific working conditions.

Principle of Operation of Piston Compressor

The piston compressor operates based on the reciprocating motion of the piston within the cylinder, following these steps:

1. Suction stage: The piston moves downward, reducing gas pressure inside the cylinder, causing the suction valve to open and allowing external gas to enter the cylinder.
2. Compression stage: The piston moves upward, compressing the gas inside the cylinder, decreasing its volume and increasing its pressure.
3. Exhaust stage: When the gas pressure reaches the desired level, the exhaust valve opens, and the compressed gas is discharged to the downstream system.

Through this cyclic process, piston compressors efficiently compress gases, making them ideal for applications requiring high discharge pressure and large discharge volumes.

Characteristics of Piston Compressor

1. High displacement and low speed design: Reduces noise and vibration, provides stable high displacement, and ensures suitability for long-term operation.
2. High volumetric efficiency: The volumetric compression principle enables efficient output even in a compact unit.
3. API 618 standard compliance: Strict adherence ensures safety and reliability in high-pressure environments such as oil and gas.
4. Diversified model selection: M type, D type, L type, P type, and more than 60 product specifications available. Compressor stages can be flexibly adjusted from first to sixth stage to meet different pressure requirements.
5. Customized service: Professional customization for specific working conditions to meet the gas type, pressure, and flow requirements of each site.
