摘要
针对除冰加液过程中的流量脉动和振动,以双作用式大流量除冰液往复泵为研究对象,给出了工作原理和运动学模型,通过AMESim软件进行建模仿真,得到蓄能器在不同充气压力下安装位置前后的流量曲线,计算出流量脉动率,并分析了改变配流球阀质量后的流量输出和脉动情况,最后通过实验验证仿真分析的合理性.结果显示,当蓄能器压力略低于平均工作压力时,脉动抑制效果较佳;减小阀芯质量不仅可以减小流量脉动,还能改善阀芯的启闭特性.实验结果验证了仿真模型的可靠性,为民航除冰工艺装备设计提供依据.
Aiming at the suppression of pulsation and vibration in de-icing liquid filling, we selected double-acting large flow reciprocating pump as the object and proposed the principle as well as the kinematic model. According to the modeling and simulation by AMESim, we set different pressures of energy accumulator and gained flow curves which were captured before and after the installation position, then calculated the flow pulsation rate. We also analyzed the output flow and the pulsation rate by changing the weight ofone-way ball check valve. Then, we tested the validity ofsimulation. Theresults demonstrated that the pulsation suppression result is relatively good when the energy accumulator pressure is slightly lower than average working pressure; besides, decreasing the weight of one-way ball check valve can suppress the flow pulsation and improve the on-offcharacteristic of ball valve. Moreover, the results also testified the dependability of modeling and simulation and provided a reference to the related equipment design and industrial applications.
