A compressor is a device used to compress air (or any gas) from a low inlet pressure (usually atmospheric pressure) to a higher desired pressure level.
COMPRESSORS • A compressor is a device used to compress air (or any gas) from a low inlet pressure (usually atmospheric pressure) to a higher desired pressure level. • In pneumatic systems, compressors are used to compress and supply the required quantities of air. • As per the laws of perfect gas, the compressor increases the pressure of the air by reducing its volume. • There are two basic types of compressors, based on their method of energy transfer and pressure generation. They are : 1. Positive displacement compressors, and 2. Dynamic type compressors. • Positive displacement compressors work on the principle of increasing the pressure of a definite volume of air by reducing that volume in an enclosed chamber. • Dynamic compressors, also known as turbo compressors, employ rotating vanes or impellers to increase the pressure of the air. • The detailed sub-classification of compressors are presented in Fig.11.1. However, the study of piston-, screw-, and vane-type compressors are more important from our subject point of view.1. What is a Compressor ?
