Modeling Of High Pressure Radial Piston Pumps Pulkit Agarwal by Pulkit Agarwal instant download after payment.

A comprehensive multi-domain simulation tool for investigating the operation of radial
piston machines has been developed in the present study. The simulation tool is capable
of analyzing the displacing action of the machine parts as well as the power losses
occurring in the lubricating interfaces which makes it useful for supporting the design
process of radial piston units. The reference machine analyzed in this study is a radial
piston pump of rotating cam type design used for high pressure applications. Though the
modeling process and calculations in this analysis pertain mostly to this specific design,
the concepts involved and numerical procedure can be applied to generic designs of
radial piston machines. A lumped parameter based model for complete hydraulic system
of the pump has been formulated which can predict the main flow parameters in the
pump namely flow rate and pressure at pump outlet. This model can be easily coupled
with other hydraulic components present in a circuit to model the systems level
performance of the machine. However, an improvement in pump design calls for a
detailed investigation of internal components present in the pump specifically the
lubricating interfaces present in the pump. The lumped parameter model is capable of
generating boundary conditions to simulate the flow behavior in these lubricating
interfaces. A separate model for piston-cylinder interface and cam-piston interface has
been developed in this study to incorporate the detailed features involved in each of them.
