Method to reduce the Oil Pressure during HPHT diamond synthesis: FEM simulations and experiments
CrystEngComm, 2020Co-Authors: Chunxiao Wang, Liangchao Chen, Xinyuan Miao, Liang Zhao, Xiaopeng JiaAbstract:Here, a new type of supercharged cell assembly is proposed that can effectively reduce the Oil Pressure during high-Pressure, high-temperature (HPHT) diamond synthesis. Finite element simulations showed that the Pressure at the center of the synthesis cell increased with the volume of the pressurization block, and the proportion of materials with high compressive strength in the cell determined the central Pressure. The experimental results verified that, under the same conditions, the Oil Pressure decreased by 2.25 MPa for each 1 mm increase in the height of the pressurization block, and this was consistent with the FEM simulations. The results can be used to optimize the design of high-Pressure synthesis cells to decrease the Oil Pressure during diamond synthesis and reduce experimental costs by prolonging the service life of WC-anvils.

the effect of Oil Pressure and temperature on barrel film thickness and barrel dynamics of an axial piston pump
Meccanica, 2012Co-Authors: J M Bergada, D L Davies, Sushil Kumar, J WattonAbstract:Efficiency improvement in piston pumps and motors is a major task in pump development. Just a small improvement in efficiency can have a significant financial impact, particularly on large manufacturing plants employing many large-power pumps. According to the bibliography, effort has been concentrated in studding slipper swash plate leakage, forces, torques and slipper dynamics, but less attention has been given to the understanding the barrel dynamics and the inherent clearance between the barrel and the port plate. This paper clarifies the understanding of the complex barrel dynamics, pointing out how barrel-port plate film thickness depends on Oil Pressure and temperature. The paper demonstrates that mixed lubrication exist between the barrel face and the port plate under some of the conditions studied, proving that elastic metal to metal forces play an important role when studding barrel dynamics. According to the authors, more effort should be considered into properly designing the barrel sliding surface since both volumetric and mechanical efficiencies are very much dependent on this design.
