In the recent years, as the proportion of mechanic industry in nation economy increases, the requirement for safe operation of mechanic equipment is higher and higher. due to that all kinds of technology are progressively applied to mechanic equipment fault and diagnosis, such as signal processing, pattern recognition, etc., mechanical equipment fault and diagnosis technology has been developed rapidly all over the world. the reciprocating pump as a part of mechanic equipment field takes up very important station in production department, such as the petrochemical industry. because its applications are very widely, making researchs about its fault and diagnosis has important meaning. though people have already made out some researchs and obtained some research results, but the total diagnosis level is not still very high. based on former research results, according to the strong non - stationary characteristic of the pump valve signal of the reciprocating pump, this text introduces hilbert - huang transform ( abbreviated as hht ), and diagnosed the pump valve faults of the reciprocating pump well
雖然人們已對其開展了不少研究並取得了一些研究成果，但總的診斷水平還不是很高。本文在基於前人研究成果的基礎上，根據往復泵泵閥信號的強非平穩特性，引入了希爾伯特-黃變換（簡稱hht ） ，對往復泵泵閥較好地進行了診斷。往復泵由於其結構復雜，激勵源多，故其信號為強非平穩信號，對其進行故障特徵提取和診斷比較困難，所以本文主要研究了往復泵泵閥振動信號的特徵提取方法。
