b'HYDROCAMSystem READYCalculationsAdditional HYDROCAMSystem Calculations: Calculations are based upon the example as shown on page 4. These will assist in understanding optimal working conditions. It may be necessary to calculate your total system working pressure and totalforce required to drive the H-1 pump.Calculate the Required Total Volume of Oil:VT = Total # of H-2 units (N) x Volume per mm of stroke (from H-2 chart on page 7) (VC) x Stroke length of each H-2 unit (SL)English: VT = 2 units x .0491 in3 per mm x 25 mm stroke length = 2.455 in3Metric: VT = 2 units x .804 cm3 per mm x 25 mm stroke length = 40.2 cm3For this example, we have chosen an H-1 5 pump, because the maximum volume of this size pump is 3.051 in3 (50 cm3) (from H-1 chart on page 9).Note: Never use more than 90% of the H-1 units maximum oil volume.Calculating the H-1 Piston Rod Travel:Ht 5 (from H-1 chart on pg 9)+ ( VT (from above calculation) ) = Piston Rod TravelV1 (from H-1 chart on page 9) 0.02 inEnglish: .315 in + (2.455 in33.4636 in3 per in0.02 in) = 1.004 inch piston rod travelMetric:8 mm+ (40.2 cm32.235 cm3 per mm0.50 mm) = 25.49 mm piston rod travelCalculating Optional Stroke Gauge Ring Thickness (used for set-up):Ht 3 (from H-1 chart on pg 9)Piston Rod Travel (from above calculation) = Stroke Gauge Ring ThicknessEnglish: 1.22 in1.004 in = 0.216 inches Metric: 31 mm25.49 mm = 5.51 mmFor this example, we will use theH-1-5pump (refer toH-1chart)Calculating Total Internal Working Pressure:Maximum System Working Pressurex Required Tonnage(from Step #3 on pg. 4) = Total Working PressureMaximum Rated Force of H-2 Unit(from H-2 chart on pg. 7)English: (5,802 psi7,050 lbs.) x 6,000 lbs. = 4,938 psiMetric: (400 bar3,198 daN) x 2,765 daN = 346 barCalculating Total Required Force to Drive H-1:Piston Area of H-1 (from H-1 chart on pg. 9) x Total Working Pressure (from above)English: 3.464 in2 x 4,938 psi = 17,105 lbs.(2,000 lbs. = 8.6 U.S. tons)Metric: 22.35 cm2 x 346 bar = 7,733 daN (1,000 N = 7.7 metric tons)10'
