The basic configuration and principle of WH-800 centrifuge were introduced. And then we introduced and improved the singular value distribution of the Singularity Value Decomposition about track matrix of attractor reconstructed by time series, which imported the autocorrelation function. The analysis of the test signals shows that the singular value distribution method is very effective in depressing noise and detecting faults of the centrifuge, which offers a new method to the faults diagnosis of the centrifuge.
