Title:
遠心ターボ機械の余寿命を求めるシステムおよび方法
Document Type and Number:
Japanese Patent JP5587270
Kind Code:
B2
Abstract:
A centrifugal turbomachine includes an impeller and a speed sensor arranged to detect a speed associated with an impeller speed. A temperature sensor is arranged to detect a temperature associated with an impeller exit temperature. A controls system has impeller parameters, which includes the impeller speed and exit temperature. A calculation methodology is used to mathematically manipulate the impeller parameters to determine a remaining life of the impeller. A program response, such as a warning indication, is triggered by the control system in response to the remaining life reaching a threshold. The controls system monitors the speed and temperature of the impeller. The controls system internally calculates the remaining life based upon the speed and the temperature. In one example, a change in remaining life is calculated in response to a change in speed that results in an impeller stress that exceeds an endurance strength for the impeller.
