Two Stage Air Compressor
TITLE:
Two Stage Air Compressor
ABSTRACT:
The purpose of this experiment is to investigate the effect of delivery pressure on the performance of reciprocating air compressor. The usage of an air compressor is to increase the amount of air in a confined space and use the compressed air to generate power. The Cussons P9050 Two Stage Reciprocating Air Compressor Test Set is used in this experiment. In the beginning the system is set up to a single stage air compressor and it is operated at a constant speed. Then, by manipulating the air receiver, the dynamometer load, the inlet air flow orifice manometer reading, outlet and inlet temperature are recorded. From the results gathered, the values of air flow, power output and efficiencies are calculated. Three graphs representing the relationship between the performance of the air compressor and the pressure, represented by the air flow, the power output and the efficiencies are also plotted. From the graphs we can see that the discharge pressure, isothermal efficiency, T and isentropic efficiency, S increases whereas the volumetric efficiency and vol decreases. The errors will be discussed later.
INTRODUCTION:
Two-stage air compressors are used in a range of industries, such as in the manufacture of chemicals and fertilizers. They supply power to pneumatic tools like ratchet wrenches spray guns and air nailers. They can be found in gas stations and major manufacturing plants. They are usually stationary and can be used to supply power to a variety of tools for a long period of time.
A two-stage air compressor is a heavy-duty air compressor that uses two cylinders. An air compressor is a device that increases the amount of air in a confined space. Confined air builds pressure and generates power for industrial, commercial and personal uses. The two-stage air compressor comes with two pistons. One pumps air from one cylinder to a second cylinder, and this increases the air pressure for generating the
