Transmission Loss Experiment and Characteristics Analysis of Hydraulic Circuit with Multilayer winded Hydraulic Hose

Abstract:

The hydraulic circuit with a long distance multilayer winded hydraulic hose was studied. Through transmission loss experiment, the characteristics of fluid pressure loss in this special hydraulic circuit was discovered. The experiment indicate that turbulence could also be caused by the interaction between the hydraulic hose and oil. With the whole length of hydraulic hose unchanged, the pressure loss increases with the increase of the layers of the hose curves. And in laminar status, the pressure increases linearly. The concept of hydraulic resistance was introduced to derive the half experience formula for calculating the pressure loss in the circuit of multilayer winded hydraulic hose.
