摘要
针对液压驱动式压裂泵流体脉动问题,分析了其脉动机理,通过对基于蓄能器-增压缸组合的传统脉动抑制回路进行理论研究,提出了一种基于蓄能器-增压缸组合的自适应脉动抑制方法,并对自适应脉动抑制特性进行理论分析,研究了系统稳态压力等参数的变化对其脉动抑制效果的影响.利用MATLAB/Simulink软件建立脉动抑制回路数学模型,对两种抑制方法进行对比仿真研究,结果表明:相比较基于蓄能器-增压缸组合的脉动抑制方法,自适应方法具有更好优的抑制效果,其脉动压力幅值是传统方法的 45%～86%左右,且具有一定的自适应性、良好的稳定性和灵活性.
Abstract
Aiming at the problem of fluid pulsation in hydraulic driven fracturing pump,the pulsation mechanism was analyzed.Through theoretical research on the traditional pulsation suppression circuit based on accumulator and booster cylinder combination,an adaptive fluid pulsation suppression method based on accumulator and booster cylinder combination was proposed,and the adaptive pulsation suppression characteristics were theoretically analyzed.The influence of parameters such as steady pressure on pulsation suppression was studied.MATLAB/Simulink software was used to establish a mathematical model of fluid pulsation suppression loop,and the two suppression methods were compared and simulated.The results showed that:compared with the pulsation suppression method based on accumulator and booster cylinder combination,the adaptive method has better suppression effect,and its pulsation pressure amplitude is about 45%-86%of that of the traditional method,and it has certain adaptability,good stability and flexibility.
