Description

How They Work

1. Screw Rotation: Two helical screws rotate within a casing. The male screw has external threads, while the female screw has internal threads.
2. Suction: As the screws rotate, they create a vacuum in the chamber, causing the gas to be drawn into the compressor.
3. Compression: The gas is trapped within the chambers as the screws rotate. The decreasing volume of the chambers compresses the gas.
4. Discharge: The compressed gas is discharged from the compressor through an outlet port.

Advantages of Screw Compressors

• High efficiency: Screw compressors generally offer high efficiency due to their smooth, continuous operation.
• Continuous flow: Provides a steady, pulsation-free flow of compressed air.
• Long lifespan: With proper maintenance, screw compressors can have a long operational life.
• Quiet operation: Relatively quiet compared to other types of compressors.
• Wide range of applications: Suitable for a variety of gases and operating conditions.

Applications

• Industrial processes: Used for powering pneumatic tools, conveying materials, and operating machinery.
• Refrigeration: Used in refrigeration systems for compressing refrigerants.
• Petroleum industry: Used for compressing natural gas and refinery gases.
• Chemical industry: Used for compressing process gases.
