3. COMPRESSOR

4. INTRODUCTION A  compressor  is a mechanical device that increases the  pressure  of a  gas  by reducing its  volume . An  air compressor  is a specific type of gas compressor. As gases are compressible, the compressor also reduces the volume of a gas.

5. TYPES OF COMPRESSOR There are following types of compressors Positive displacement 1) Reciprocating compressor 2) Ionic liquid piston compressor 3) Rotary screw compressor 4) Rolling piston 5) Diaphragm compressor

6. Dynamic 1)Air bubble compressor 2)centrifugal compressor 3)Diagonal or mixed flow compressor 4)Axial flow compressor Centrifugal compressor

7. Reciprocating Compressor A reciprocating compressor or piston compressor is a positive displacement compressor that uses pistons driven by a crank shaft to deliver gases at high pressure. This type of compressor uses piston cylinder arrangement to compress the air

8. There are two types of reciprocating compressors 1)single acting reciprocating compressor:- In single acting reciprocating pump piston reciprocate only In one dire- on.

9. 2)Double acting reciprocating compressor:- In double acting reciprocating pump both side are effectively use to com- press the air

10. SPECIFICATION OF COMPRESSOR USED Pressure :- 90 PSI = 6.201 bar Capacity :- 8L Power :- 1HP Zero maintenance oil free single acting reciprocating compressor

11. SINGLE ACTING RECIPROCATING PUMP In this type of compressor , the piston back and forth inside the cylinder and compress the air . There are two sets of valves that take care of air intake and exhaust

12. Working :- The compressor takes inside successive amount of volume of air from int- ake valve and confined it in closed surface at that time piston moves do- wnwards the with the closure of intake valve. Then there is compression of air by reducing its volume. Now the piston moves upward and compress the air and then displace the compressed air through exhaust valve.

13. ADVANTAGES :- Relatively cheap Easy maintenance Suitable for high pressure Large range of horsepower

14. DISADVANTAGES Sound too much. You have to arrange a room for it or to put it into isolating box High outlet temperature of compressed air High oil content in the pipe

15. APPLICATION Reciprocating pump generally seen where there is requirement of high pressure and low flow . Mostly where the air is used for hand-tool , cleaning dust, small paint jobs, commercial uses. etc
