In this paper predictive-based maintenance and condition-based maintenance have been studied for water pump stations. Measurements of vibrations in suitable places, analysis of the vibration trend and spectrums have been dealt with in details. Using the trend of vibrations, existence of a fault in machinery can be detected. The vibration spectrums can also be used in fault diagnosis. Furthermore, in this paper the practical results of using a condition-based monitoring system in one of Tehran’s water pump stations has been presented. Using this method, the existing faults have been detected before the critical situations and the proper repair has been done on the machinery. Using vibration signals for condition monitoring and fault diagnosis started for the first time at Tehran Water and Wastewater Company. Promising results of this method can be used for other water and wastewater companies.
