Abstract
A pump health analysis method and a pump health analysis device using the same are provided. A standard vibration curve of a standard pump is obtained. The standard vibration curve is converted from a time domain to a frequency domain to obtain a first frequency distribution curve. A sample vibration curve of a sample pump is obtained. The sample vibration curve is converted from the time domain to the frequency domain to obtain a second frequency distribution curve. The first frequency distribution curve is compared with the second frequency distribution curve by using a cosine similarity algorithm to obtain a health index of the sample pump.
