| Abstract(in English) | We have studied the possibility of prediction for the in-service life(abbreviated as ISL, hereinafter)of dry pumps from the unstable non-stationary motor current which is observed before over-load pump stopping. A model describing the data as-measured(i.e.non-stationary model)and stationary models converted from the non-stationary one have been evaluated. The data were obtained from an accelerated test performed under TEOS process. It has been found that the stationary models can predict ISL in more stable manner than the non-stationary ones. According to the analytical result of each model, it is concluded that, in the view of practice of ISL prediction, the importance is at the selection of models that leads to stable prediction resulting in high certainty of ISL prediction. |
