1 Definition of overhaul
Watercooling unit
It must be maintained once a year WalMart shall be responsible for replacement of lubricating oil oil filters and drying filters The owner shall be responsible for inspection of the whole unit to ensure it is under a normal running condition and find out hidden danger and potential risks in order to save energy and prolong service lifetime It is possible to cause potential troubles without appropriate maintenance
Overhaul covers important overhaul and medium overhaul it is also divided into unit overhaul and compressor overhaul Medium overhaul refers to dismantling the compressor to check and clean internal surface without replacing any components And important overhaul refers to replacing the seriously worn internal parts Unit overhaul refers to maintenance can be done only after introducing the coolant out of the unit which is also called important overhaul Other maintenance treatments are called medium overhaul All of these shall be the responsibility of the owner
Pneumatic cooling piston units
Same as the abovementioned maintenance method They are under the owner’s responsibility
Medium overhaul shall be done like this remove the compressor out of the unit open the cover to clean the motor Check the shaft linkage bar and piston to find whether they are over worn and then they can be reinstalled if no need to replace If the parts are found to be over worn and need to be replaced we call it important overhaul for the compressor
