centrifugal compressor for the metallurgical industry

Centrifugal compressors are typically used where high volume gas compression is required and are widely applied in industries such as oil, gas, chemical, metallurgical, and air conditioning. The equipment utilizes advanced fluid mechanics principles and efficient gas processing technology, delivering stable gas compression solutions for various industrial scenarios.

Features of Centrifugal Compressor

1. High efficiency: Optimized gas flow path and high-speed impeller rotation minimize resistance and energy loss, resulting in exceptional energy efficiency.
2. Stable operation: Simple structure with few parts ensures minimal vibration and low noise, supporting long-term stable operation.
3. Wide adjustable pressure range: Compressor parameters can be flexibly adjusted for different working conditions and gas compression needs.
4. Strong adaptability: Suitable for compressing a variety of gases, including air, nitrogen, natural gas, hydrogen, and ethylene.
5. Compact design: Smaller footprint compared to similar equipment, ideal for limited-space plant and equipment layouts.

Working Principle of Centrifugal Compressor

The centrifugal compressor operates based on centrifugal force. As the high-speed impeller rotates, gas enters through the inlet and is accelerated. The impeller transforms the gas into a high-velocity stream, pushing it into the compression chamber with centrifugal force. This process converts the kinetic energy of the gas into pressure energy, realizing efficient gas compression.

1. Inlet stage: Gas enters the impeller from the inlet and is accelerated.
2. Centrifugal force stage: The impeller’s rotation increases gas speed, pushing it outward toward the shell.
3. Compression stage: Gas flows along the shell wall, speed gradually converts to pressure, achieving the required exhaust pressure in the compression chamber.
4. Exhaust stage: Compressed gas is discharged through the exhaust port, completing the process.
