Abstract
A pump life prediction system and methods for predicting pump life of a pump are disclosed. A method may include monitoring pump operating conditions. A value indicative of cavitation damage is determined based on the pump operating conditions. A pump life remaining is determined based on the value. The method may also include outputting an indication of the pump life remaining.
Claims20
A method for predicting pump life of a pump, comprising:
- monitoring pump operating conditions;
- determining a value indicative of cavitation damage based on the pump operating conditions, wherein the value is a rate of cavitation damage accumulation;
- determining a pump life remaining based on the value;
- and
- outputting an indication of the pump life remaining.
