PUMP EFFICIENCY MEASURING SYSTEM

摘要

The present invention relates to a pump efficiency measuring system which includes a first temperature sensor which is installed on an inlet of a pump and which measures the temperature of an inflow of water; a second temperature sensor which is installed on an outlet of the pump and which measures the temperature of an outflow of water; a first pressure sensor which is installed on the inlet of the pump and which measures the pressure of the inflow of water; a second pressure sensor which is installed on the outlet and which measures the pressure of the outflow of water; a power measuring unit measuring power supplied to the pump; and an analysis unit which calculates the efficiency of the pump by receiving the information measured by the first and second temperature sensors, the first and second pressure sensors, and the power measuring unit. The pump efficiency measuring system supports the measurement of the hydraulic efficiency and the thermodynamic efficiency of the pump and can autonomously correct a temperature value of the temperature sensors measuring the temperatures of the inflow of water of the inlet and the outflow of water of the outlet, thereby improving user convenience and the precision of the measurement.
