Study of kinetics in the power end of multi - cylinder single - action reciprocating pump 多缸单作用往复泵动力端动力学研究
2.
The study shows that with the method offered the useful information reflecting the condition of the reciprocating pump can be effectively extracted from the highly noised signal by soft - thresholding de - noising method at the power end of the reciprocating pump 通过对振动信号的波形特征提取表明，该方法能在很高的背景噪声下有效提取反映往复泵状态的有用信息。
