| Abstract: | How to separate two rotors' unbalanced weight from beat is the key of whole-machine balancing for dual rotor system with little rotation speed difference. Firstly this paper introduces of the principle and method for whole machine balancing for this type dual-rotor systems, then discusses the design of the portable and intelligent whole-machine balancing instrument in detail from the following key points such as picking up beat signal, capturing the value of wave crest and calculating the phase of unbalanced weight. Then the instrument is used for a horizontal decanter centrifuge, WL-350, in the laboratory and a satisfactory result is obtained. It is proved that the development of the instrument is successful. |
