Abstract
|
Hydraulic technology used in the working medium is a liquid, which flows in the system of components such as hydraulic pumps, cylinders, valves and pipes . In such a liquid flow system , there are a variety of complex flow path, the liquid flow in these complex flow channel characteristics when the composition of the fluid components of the system performance and even the entire fluid power transmission and control system performance have a crucial important . The main problems of the existing high-pressure axial piston pump runner system : ( 1 ) internal flow channel energy loss , noise , and low efficiency in energy consumption ; ② piston pump flow channel structure design is often based on experience to rarely use the finite element method ; ③ piston pump runner flow structure rarely more rare , especially in the structure of the flow field research on the piston pump runner system performance impact . The established 3D geometric model of fluid flow in the high-pressure axial piston pump runner , the use of three-dimensional fluid analysis technology of high pressure axial piston pump flow field numerical simulation of the flow channel , and the calculated results visualization graphics The image in the form given . On this basis , qualitative analysis of different flow channel model relationship between the different speed and load flow field ( velocity, pressure field) , as well as the flow field structure and noise, the relationship between the energy loss . The structure of the axial flow channel to optimize the design to provide the basis for , and laid the foundation for the design of high efficiency , low energy consumption , low noise hydraulic pump and fluid piping systems .
