自适应回路在压裂泵流体脉动抑制中的应用OA北大核心CSTPCD

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.
