What are the two types of positive displacement air compressors?

• A. Rotary and Reciprocating
• B. Centrifugal and Axial
• C. Pneumatic and Hydraulic
• D. Auger and Diaphragm

Answer: (A)

Positive displacement air compressors are designed to move air by trapping a fixed volume and forcing that volume into a discharge pipe. The two primary types of positive displacement air compressors are rotary and reciprocating compressors. Rotary compressors operate using rotating elements, which can include mechanisms like screws or vanes to compress the air. They are known for their smooth operation and are typically more efficient at higher volumes of air. This makes them ideal for continuous operation in industrial applications. Reciprocating compressors, on the other hand, use a piston-driven mechanism to compress air. The piston moves back and forth in a cylinder, drawing in air and then compressing it with each stroke. These compressors are widely used for their ability to provide high pressure in smaller volumes and are often found in various applications where compressed air is required intermittently. Understanding these types of compressors is crucial, as they each have specific applications and advantages depending on the required pressure and volume of air, as well as operational efficiency under varying load conditions.
