What design feature characterizes a screw compressor?

• A. Rotating vanes
• B. Helical lobes
• C. Sliding pistons
• D. Multiple stages

Answer: (A)

A screw compressor is characterized by the use of helical lobes. These lobes rotate against each other to compress the gas in a continuous process, providing efficiency and reliability. The design allows for a smooth and consistent flow of compressed air or gas, which is crucial for many industrial applications. The helical design of the lobes minimizes pulsations and vibrations, resulting in a quieter operation compared to other types of compressors. This feature is particularly beneficial in environments where noise levels need to be controlled. The sealing ability of the helical lobes ensures that there is minimal leakage of compressed gas, making the operation more energy-efficient. The other design features listed, such as rotating vanes, sliding pistons, and multiple stages, apply to different types of compressors and do not accurately describe the unique mechanism of a screw compressor. Understanding this distinction is important for identifying the right compressor for specific applications in various industrial and mechanical settings.
