BASIC OF ACTUATING

HIDRAULIC Make a move constructively liquid / oil

PNEUMATIC Make a move constructively air

ELECTRIC Make a move constructively electromagnetic

N0 NATURE OF PNEUMATIC HIDRULIC ELECTRIC

1 BASIC

COMPONENT HOLD UP TO OVER LOAD

PROTECTION OF COMPONENT WITH HIGH COST

NOISE FROM AIR RELEASE

NOISE FROM PIPE IN HIGH PRESSURE

NOISE FROM HAPPENED CONTACTOR

2 ENVIRONMENTAL INFLUENCE

NOT CHANGE AT TEMPERATURE

EASY CHANGE AT TEMPERATURE

NOT CHANGE AT TEMPERATURE

BLAST PROOF, DANGEROUS OF HIGH HUMIDITY

LEAKAGE YIELD CONTAMINATION AND MAKING BURNING

USING OF PROTECTION FROM FIRE AND BLAST

3 POWER COST HIGH IF COMPARE TO ELECTRICAL

HIGH IF COMPARE TO ELECTRICAL LOWER

4 SETTING

SETTING OF ENERGY EASY, WITH SETTING PRESSURE

SETTING OF ENERGY VERY EASY

SETTING OF ENERGY LIMITED AND HIGH COST

SETTING SPEED WITH VALVE

GOOD OF SETTING IN MOVEMENT SLOWLY --------

5 SAVING AND CONNECTING

UNLIMITED SAVING WITHOUT COSTLY EXPENSE

LIMITED SAVING WITH COSTLY EXPENSE

DIFFICULT SAVING AND HIGH COST

VERY EASY CONNECTING WITH PIPE

LIMITED CONNECTINGVERY EASY CONNECTING WITH CABLE

6 CONTROL AND OPERATION

NOT DIFFICULT OPERATION

OPERATION MORE DIFFICULT IF COMPARE WITH PNEUMATIC

OPERATION WITH PROFESSIONAL SKILL AND VERY DANGEROUS

EASY CONTROL AND HIGH SAFE

PIPE THE RETURN OIL NEEDED

ERROR CONTROL CAN TO MAKE TROUBLE
