Abstract :
Pumps are used widely in industrial plants, energy systems, ships, etc. Generally, they consume nearly 20% of the each nation´s total electrical energy. During pump´s operation, energy loss can be huge if its efficiency is low. Usually, the pump should be repaired or replaced if it cannot operate at high enough efficiency. By measuring pump efficiency, the loss can be estimated. Currently, there are two methods to measure pump efficiency, the thermodynamic method and traditional technique. Each one has its advantages and disadvantages. The features of these two methods and the comparison between them are introduced in this paper. Pump efficiency instrumentation (PEI) is a device which was made to analyze these two methods. PEI continuously monitors parameters at real-time and saves all information in special file type. The information collected from PEI is advantageous for the management of pump´s electrical energy; hence proper maintenance plan can be conveniently given in advance.
