Category: Reciprocating Air Compressors

The theoretical p−V diagram for single acting compressor is shown in Fig.12.4. The line 4–1 represents the suction stroke. The air is then compressed adiabatically as shown by the curve 1–2 in Fig. 12.4. It is then forced out of the cylinder at constant pressure p2, as shown by the line 2–3. The work done is represented by the area…

The schematic arrangement of a single-stage reciprocating compressor is shown in Fig. 12.3. It consists of a cylinder with cooling jacket, piston, connecting rod, crank, suction valve, and delivery valve. The piston will be making to-and-fro motions through the crankshaft arrangement and generally run by an electric motor, diesel engine, petrol engine, or steam engine. During…

The several uses of compressed air are as follows:

Compressors are mechanical devices used for increasing the pressure of a gas. Compressors used for producing high pressure air are called air compressors. Air is drawn from the atmosphere by suction process, which is then compressed to the required pressure and delivered to the receiver. Air compressors may be classified as shown in Fig. 12.1. Figure…
