Pump efficiency of a fluid pump
First Claim
1. A computer implemented method of monitoring a condition of a pump, comprising:
- receiving, at a computing device, one or more signals indicative of one or more of a characteristic of a fluid flow at a first point on a flow path, the characteristic of the fluid flow at a second point on the flow path, and a difference in the characteristic of the fluid flow at the first point and at the second point, wherein the flow path is a path through which a fluid leakage flows from a case drain of the pump;
determining, by the computing device based on the one or more signals, a fluid leakage flow rate through the flow path;
determining, by the computing device, a pump efficiency based on the fluid leakage flow rate and a nominal fluid flow rate for the pump, wherein the nominal fluid flow rate is an optimal fluid flow rate for the pump when operating with a minimal amount of the fluid leakage;
determining, by the computing device, whether the pump efficiency has dropped below a designated efficiency threshold;
if the pump efficiency has dropped below the designated efficiency threshold, predicting, by the computing device, an impending pump failure; and
in response to predicting the impending pump failure, generating, by the computing device, a first alert indicative of the impending pump failure.

Abstract
Systems and methods determine a pump efficiency of a fluid pump. A characteristic of fluid flow of a fluid is monitored at a first point and at a second point on a flow path of the fluid pump. Fluid leakage that is a difference in the characteristic of the fluid flow at the first point and the second point is determined. The fluid leakage is compared to a nominal fluid flow for the fluid pump. The pump efficiency for the fluid pump is generated based on the comparison of the fluid leakage to the nominal fluid flow. The pump efficiency is an indicator as to an amount of fluid leakage that is leaked from the flow path as compared to the amount of fluid leakage when operating with the minimal amount of fluid leakage.
