IT ALL STARTED WITH PASCAL

HYDRAULIC SYSTEM OPERATING EFFICIENCY IS MEASURED BY COMPARING THE POWER DELIVERED BY THE SYSTEM TO PERFORM USEFUL WORK WITH THE TOTAL POWER THAT IT SHOULD BE CAPABLE OF DEVELOPING. THE POWER IS DETERMINED BY TWO MAJOR OPERATING FACTORS: (1) THE RATE OF FLOW (IN GALLONS PER MINUTE) OF FLUID MOVING THROUGH THE SYSTEM DURING THE OPERATING CYCLE, AND (2) THE HYDRAULIC PRESSURE DEVELOPED BY THE SYSTEM DURING THE CYCLE. CYCLE TIME DEPENDS UPON THE SYSTEM'S ABILITY TO MAINTAIN THE NECESSARY RATE OF FLOW OF FLUID AND TO DEVELOP THE REQUIRED HYDRAULIC PRESSURE TO OVERCOME THE LOAD. THE THREE BASIC TESTS OF HYDRAULIC SYSTEM EFFICIENCY ARE: CYCLE TIME, FLOW RATE PRESSURE. THESE TESTS ARE DISCUSSED AND DESCRIBED, AS WELL AS PUMP TESTS AND RELIEF VALVE TESTS.
