FOLLOWING FACTORS EFFECT THE VOLUMETRIC EFFICIENCY OF AIR COMPRESSOR:-
- CLEARANCE BETWEEN THE PISTON AT T.D.C AND CYLINDER COVER. LARGER THE CLEARANCE, LESSER THE AIR DISCHARGED PER STROKE AND LESSER WILL BE THE VOLUMETRIC EFFICIENCY OF AIR COMPRESSOR.
- SLUGGISH OPERATION OF VALVES.
- LEAKY PISTON RINGS.
- INEFFECTIVE COOLING DUE TO CHOKING OF INTER AND AFTER COOLER OR LACK OF WATER SUPPLY.
- HIGH TEMPERATURE OF AIR AT SUCTION OF FIRST STAGE.
- DIRTY AIR FILTER.
