A Model Investigation on the Pressure Transducer Dynamics for Measurements in Lubricating Vane Pumps: Influence of Dissolved Air and of Transducer/Tubing Geometry 2010-32-0059

Variable-displacement lubricating pumps are an attractive solution for reducing fuel consumption and emissions in motorcycle engines. In this prospective, modeling and experimental analysis are very useful means for a deeper understanding of pump operation and for effectively implementing pump control.Zero-dimensional simulation results of a 7-vane pump were compared with the experimental data of dynamic piezo-resistive pressure transducers fitted into the casing of a pump prototype, which was operated under steady-state conditions at different rotational speeds and eccentricity values.The experimental data exhibit oscillations which were explained by taking into account the pressure transducers dynamics, as a result of the transducer location in the pump casing, of the air dissolved in the hydraulic fluid and of the geometry of the tubing/transducer system. The investigation shows that the transducer dynamics deteriorate as the diameter or length of the connections increase and as the dissolved air quantity increases.
