18. COOLING SYSTEMS Cylinder Cooling Cooling Methods

19. MULTI – STAGE COMPRESSION

20. Multi – stage compressor

21. Advantages of Multi – Staging Saving in power Reduces the maximum gas temperature in the cylinders Reduction of the pressure differential across each cylinder

22. LUBRICATION Reduce friction between the moving parts. Minimize wear. Dissipate frictional heat through cooling and heat transfer. Flush away entering dirt as well as wear debris. Reduce gas leakage. Protect parts from corrosion. Minimize deposits.

23. Lubricant Distribution Methods Forced circulation system. Splash system

24. FORCE – FEED LUBRICATION

25. SPLASH LUBRICATION

26. CLASSIFICATION Single or double acting. Single stage or multi – stage. Trunk or compressors with crosshead. Cylinder (s) arrangement.

27. Cylinder Arrangements
