Numerical Simulation For XYZ-100 Thin Oil Station's Pipe Flow Field

Thin Oil station is a major lubrication equipment used to lubricate the centralized hydraulic lubrication. XYZ-100 thin Oil station adopt to traditioal design methods for C5101A / B reciprocating compressors to provide lubrication. Because of too large pipeline diameter selected, too large size of equipment determines the too high manufacturing costs.With the rapid development of computer technology, as new modern design methods, finite element method and finite volume method are widely used. ANSYS software and Fluent software are application softwares designed based on these two kinds of algorithms. Applying these two kinds of application software to the product design, the product design cycle can be shorten. Hench the product design plan can be optimized by the greatst extent for reducing product design costs and manufacturing costs.Globe valve is a major hydraulic parts of XYZ-100 thin oil station. According to the flow field characteristics when it is working, employing finite element method and finite volume method, using computer graphics software Pro / E and AutoCAD to establishing bidimensional and tridimensional models about shut-off valve , and then, respectively, make the steady-state numerical simulation and dynamic based CFD technology simulation of flow field based on the finite element method(volume method ) by importing into ANSYS software and Fluent software, and derived the flow state parameters of shut-off valve in the XYZ-100 thin oil station.Thesis are as follows:1) Based on the finite element method, establish the tridimensional model of shut-off valve , simulation analysis the steady-state flow field about the tridimensional model of shut-off valve of XYZ-100 thin oil stations, reach flow field cloud charts about the speed, pressure etc.2) Based on the finite volume method, establish the bidimensional model of shut-off valve , simulation analysis the process of dynamic analysis when the vavle disc is off using the Fluent software, arrive at the characteristics of flow field when the valve disc is in the deffrent opening degrees and different various flow phenomena and pressure loss of the simulation graphics.3) Based on the finite volume method, using the Fluent simulation analysis temperature field distribution of the cooler of XYZ-100 thin oil station, obtained the conditions about the rate parameters of intake velocity of cooling water impact the temperature distribution.
