2. EXHAUSTER + COMPRESSOR
=
EXPRESSOR

3. PARTS OF COMPRESSOR
1- CRANK CASE
2-CYLINDER
3-PISTON
4-CRANK SHAFT
5-LUBE OIL PUMP
6-CONNECTING ROD
7-INTER COOLER
8-AFTER COOLER
9-FAN & FAST COUPLING
10-LOADER & UNLOADER VALVE

4. CRANK CASE
CRANK CASE SUPPORTS
THE CRANKSHAFT WITH
YHE HELP OF BALL
BEARING.
THE BOTTEM OF CRANK
CASE SERVES AS LUBE OIL
RESERVIOUR

5. CRANKSHAFT
WITH THE HELP OF
CRANKSHAFT
,CONNECTING ROD AND
LUBE OIL PUMP IS DRIVEN

6. COUNTER WEIGHT
ITS MAIN FUNCTION IS TO
BALANCE THE
CRANKSHAFT
IT IS INTRGATED WITH
CRANKSHAFT

7. CYLINDER
THERE ARE THREE CYLINDER
USED IN LOCOMOTIVE
COMPRESSOR
TWO OF WHICH ARE LOW
PRESSURE CYLINDER AND
OTHER IS HIGH PRESSURE
CYLINDER

8. CYLINDER HEAD
IT HAS FOUR PORT ,TWO OF
WHICH ARE INLET AND TWO OF
WHICH ARE OUTLET

9. LUBE OIL PUMP
LUBE OIL PUMP IS USED FOR
LUBRICATION IN WHOLE
COMPRESSOR

10. PISTON
IT IS USED TO COMPRESS THE
ATMOSPHERIC AIR AND
INCREASES THE PRESSURE
IT IS PROvIDED WITH
gROOvES FOR PISTON RINgS

11. CONNECTING ROD
BIg END OF CONNECTINg
ROD IS CONNECTED TO
CRANKSHAFT AND
SMALL END IS
CONNECTED TO
PISTON,CALLED PISTON
PIN

12. INTERCOOLER
ITS FUNCTION IS TO COOL THE
COMPRESSED AIR AND
INCREASES THE vOLUMATRIC
EFFICIENCY

13. LOADER & UNLOADER
ITS FUNCTION IS TO LOADINg AND
UNLOADINg IN THE COMPRESSOR .
TIME RATIO FOR LOADINg AND
UNLOADINg IS 1: 3
DURINg UNLOADINg COMPRESSOR
IS AT REST

14. FAST COUPLING
IT IS FITTED TO ONE END OF
COMPRESSOR .ITS FUNCTION IS TO
CONNECT THE CRANKSHAFT OF
COMORESSOR TO MAIN ENgINE
SHAFT

15. FAN COUPLING
IT IS FITTED TO OTHER END OF
COMPRESSOR .ITS FUNCTION IS
TO DRIVE THE COOLING FAN

16. AFTER COOLER
ITS FUNCTION IS TO COOL
THE COMPRESSED AIR
FROM THE HIGH PRESSURE
CYLINDER

17. NEEDLE VALVE
ITS FUNCTION IS TO
MAINTAIN THE LUBE OIL
PRESSURE

18. FEEDER VALVE
IT IS USED TO CREAT
VACCUM IN CRANK CASE

19. WORKING OF COMPRESSOR
IT IS TWO STAGE COMPRESSOR .DURING
FIRST STAGE OF COMPRESSOR SUCTION
IS DONE THROUGH A WIRE MESH
FILTER .AFTER THIS AIR ENTERS INTO
THE INTERCOOLER WHERE ITS
VOLUMATRIC EFFICIENCY INCREASES
.NOW AIR ENTYERS INTO HIGH
PRESSURE CYLINDER OF SMALLER
DIAMETER .FINALLY AIR ENTERS INTO
AFTERCOOLER AND THEN TO
RESERVIOUR

20. WORKING OF EXHAUSTER
AIR FROM VACUUM TRAIN
PIPE IS DRAWN INTO THE
EXHAUSTER CYLINDERS
THROUGH THE OPEN INLET
VALVES IN THE CYLINDER
HEADS DURING ITS SUCTION
STROKE.

22. LOADING AND UNLOADING OR
COMPRESSOR
WHEN PRESSURE OF MAIN
RESERVIOUR REACHES
10Kg/Sq.CM. COMPRESSOR
STOPS LOADINg
WHEN PRESSUSES REACHES
8Kg/Sq.CM COMPRESSOR
STARTS LOADINg

23. USE OF COMPRESSED
AIR
1-VIPER
2-SANDINg
3-HORN
4-BREAKINg
