Abstract
In the past, the reliability analysis of centrifugal pumps is usually performed by collecting a large amount of maintenance data for reliability analysis. For some failures of centrifugal pumps that are not very frequent, the corresponding maintenance data are also small. This paper proposes a reliability research analysis method based on the fact that the centrifugal pump has few maintenance data. This method uses the least squares method to estimate the Weibull distribution parameters for small sample data; then it uses Monte Carlo sampling to expand the sample capacity. The Weibull distribution parameters after the expansion of the sample capacity are estimated. Finally, the reliability index of the centrifugal pump is calculated and the reliability operation rules of the centrifugal pump under the small sample data are predicted.
