Title: Method for estimating life of centrifugal pump
Inventor: YAMAMOTO YOICHI
IPC: F04D1/00
Filed: 1995-03-31
Abstract: PURPOSE: To estimate the life accurately by performing the life estimation by estimating the amount of increase of inner leakage within a centrifugal pump only by the measurement of currents at the time of pump exit shutoff operation, in the case of performing the estimation of life by the discharge pressure: discharge flow rate characteristic of the centrifugal pump. CONSTITUTION: When the pump has become unable to discharge required flow Qx at the time of working pressure at use place being Px, it is judged that the pump has come to the end of its life. The (discharge pressure P)-(discharge flow Q) characteristic of the centrifugal pump can be approximated by the expression of P=PC-α.Q<2> . But, PC is shutoff pressure (P at the time of Q=0), and α is pressure drop coefficient.  Since the shutoff pressure PC of the pump can be operated from the expression using the amount of increase of inner leakage within the pump, pressure drop coefficient, etc., the life estimation is performed, based on the change to time passage of the amount of increase of the inner leakage, by inferring the amount of increase of inner leakage only by the measurement of currents at the time of pump exit shutoff operation thereby obtaining the shutoff pressure PC.
