Determining Hydraulic Motor Size: I recently posted some calculation in determining how to size a hydraulic motor and I had some confusion in my mind over the torque reduction . I think I have this figured out at this point and would like to post it for anyone else that may want to figure out how to calculate what size hydraulic motor you need. slideshow SOFTWARE Mecaflux standard Helps calculations fluid mechanics Here are some screenshots of the "toolbox" mecaflux standard.. Covering many cases encountered in studies of projects related to fluids, Mecaflux standard will save you precious time. pl = pump internal leakage, L/min Pump Torque The theoretical torque required to turn a pump shaft can be calculated by: T pt = ∆ pD p / 2π Where T pt = theoretical pump torque, N*m ∆ p = pressure rise across the pump, MPa Internal friction causes the actual torque demand to be greater than theoretical Æ the pump has a torque efficiency ...

pump. The load creator (hydraulic pump) was designed and fabri cated with the following criteria: (1) Adapt to different motor shaft sizes (lengths and diameters); (2) create a constant load anywhere between I and 100 hp; and (3) create a torque ranging from 25 to 500 ft Ibs. Water to cool the hydraulic oil was
