高压溢流补油阀设计与流场分析
Design and Flow Field Simulation Analysis of High-pressure Relief Boost Valve
摘要
Abstract
Based on an relief boost valve,the high-pressure structure design is carried out,and the three-dimensional model of the high-pressure relief boost valve is established.The velocity distribution,pressure change and steady flow force change of the flow field in the valve are analyzed by CFD software.The simulation results show that the velocity and pressure gradient in the conical valve port area are large,and the undesirable phenomena such as small vortices are easy to appear at the right angle near the oil outlet of the main valve body.In addition,when the valve displacement reaches 0.5 mm,the steady flow force reaches the maximum.In order to further verify the performance of the high-pressure relief boost valve,a sample of the relief boost valve with rated pressure of 45 MPa is developed.The test results show that under the condition of an inlet pressure of 42 MPa,the high-pressure overflow oil replenishment valve has a fast dynamic response,with an overshoot of 2.5 MPa and a response time of 0.047 s.When the oil replenishment flow rate increased from 10 L/min to 80 L/min,the pressure loss increased from 0.073 MPa to 0.15 MPa.This study provides a quantitative analysis basis for the optimization design of high-pressure overflow oil replenishment valves.关键词
