The velocity energy is changed into pressure energy both by the impellers and the discharge volutes or diffusers. Positive displacement compressor 5ĭynamic compressors impart velocity energy to continuously flowing air or gas by means of impellers rotating at very high speeds. Ex: Reciprocating compressors, vane compressors & so on. At constant speed, the air flow remains essentially constant with variations in discharge pressure. In the positive-displacement type, a given quantity of air or gas is trapped in a compression chamber and the volume it occupies is mechanically reduced, causing a corresponding rise in pressure prior to discharge. by compressing it).(The fluid here is generally air since liquids are theoretically incompressible).George Medhurst of England designed the first motorized air compressor in 1799 and used it in mining. Principles on which compressors work:A compressor is a mechanical device that increases the pressure of a gas by reducing its volume.Compressor is a machine which increases the pressure of a fluid by mechanically decreasing its volume (i.e. Introduction.Types of compressors.Positive displacement compressors.Dynamic compressors.Reciprocating compressor.Rotary vane compressor.Applications of compressors in industries.Conclusion 2 Jugal Panchal Branch: Computer Engineering ACTIVE LEARNING PROCESS Prepared By : NAYAK RURUBEN JITENDRA - 13BECEG121SUTHAR HARSHIL SHAILESHKUMAR 13BECEG118PANCHOLI ADITIBEN J.
