英文摘要	Egypt has a limited water resource and depends mainly on the Nile to satisfy its demands where agriculture consumes more than 80% of the water resources. There are more than 2000 pumping stations in Egypt of different systems operating under different conditions. Pumping stations are subjected to mechanical, electrical, and structural problems affecting behavior, efficiency, safety, and reliability of these stations. These stations are a part of probably the largest network of its kind as the entire volume of water flowing down the Nile (over 55.5 billion cubic meters) has to be pumped twice, once for irrigation and then back from the field to the drains. Pumping stations use large number of bearings with different types and applications. These bearings have a clear effect on the performance and efficiency of the pumps. Pump bearings in the arid regions are greatly affected by temperature, water quality, lubricants, and maintenance operations. This research focuses on analysis of damaged rolling element bearings of pumping system. The objective of the research is to enhance and control dynamic performance of pumping stations by avoiding damage and failure of bearings. The research proves that damaged bearings generate periodic, non-periodic, and transient forces causing high amplitude of vibration at high frequencies and increasing energy consumption. Bearing faults increase vibration level 85%, where power consumption increases 14% and pump efficiency decreases 18%. It is very important to take care of bearings during installation, alignment, balancing, and maintenance to assure safe and efficient pump operation for long period. As pump efficiency decreases, water power decreases and/or consumed power increases affecting water distribution and management system. Bearing faults break pumping system for long period affecting irrigation system. Optimum operation of pumping stations helps to save and manage water requirement for development and extension projects in arid regions. The measurements are performed on full scale model in the field, which proves reliable results on similar pumping stations. (C) 2013 Faculty of Engineering, Alexandria University.
