Bumping clearance can be adjusted with the help of inserting shims (thin metallic plates) in the bottom bearings. Inserting shims will move the connecting rod and the piston which will change the clearance.
The bumping clearance once found to be incorrect would have to be adjusted. The methods of adjusting the bumping clearances are as follows:
1.The cylinder head gaskets can be changed to a different thickness thus altering the bumping clearance.
2.The shims between the foot of the connecting rod and the bottom end bearing can be changed thus changing the bumping clearance.
However after adjusting the bumping clearance the clearance should be checked once again to make sure that there is no error and the clearance is within the range as specified by the manufacturers. It must be stressed that compressors are unforgiving and incorrectly maintained compressors have claimed many a lives
Compressors are used to increase the pressure of a gas. Like pumps, compressors can be classified as either kinetic machines, which includes centrifugal and axial compressors, or positive-displacement machines, which include reciprocating and rotary compressors. The compressing medium or ‘gas’ depends on the application, such as, if air is used it is termed as an air compressor. Similarly if refrigerant is used, it is known as a refrigerant compressor. The type of compressor, its discharge pressure and discharge rate is dictated by its use.
