摘要
基于STA1000大流量安全阀试验台及AMESim液压系统仿真软件对1000L/min大流量安全阀试验过程进行了建模仿真,其得出的流量-时间曲线与试验结果对比误差在5%以内。同时,针对安全阀的核心参数:内径、弹簧弹性系数和阀芯质量与试验结果之间的关系进行了进一步的研究,揭示了其与流量曲线的关系,结果显示较小的内径会引起流量振荡,增加弹簧弹性系数会导致开启后的流量下降,阀芯质量在一定范围内对流量曲线无影响。
A simulation model of large flow （1000L/min） safety -valve was established using AMESim, based on STA - 1000 test platform, the difference between simulation and test results was within 5%. And the relation between key parameters of safety valve and test result was analyzed, including inner diameter, elastic coefficient of spring and quality of valve element. The result shows that, decrease of inner diameter causes fluctuation of flow, increase of spring elastic coefficient leads to reduction of flow rate, and the quality of valve element varying within a certain range has no influence on the flow.
