摘要： 在管输企业很多机泵是用软性方法对轮胶皮联接的。胶皮具有易损和老化等特性，振动图谱上也不同于刚性联接。以抚鲅线首站喂油泵为例对其进行跟踪研究，发现软性联接具备工频弱化和１.５倍频出现峰值等特点。因此软性联接振动图谱的研究是对目前频谱监测方法的有效补充。

Abstract: There is a lot of soft rubber connection pumps used in pipe transportation plants. Rubber has such characteristics as easy to shatter and age. Its vibrant frequency is different from rigidity connection. By tracing and studying the oil-feeding pump used in FU-BA laying. It is found soft connection has such characteristics as a low in 50 Hz and a peak of 75 Hz. In a word, studying in vibrant frequency of soft connection is a kind of complement to frequency inspetion developed in plants.
