DEVELOPMENT OF A TURBINE SYSTEM TO EXTRACTION DEEP UNDERGROUNDWATER

Due to the recent lack of rainfall, the undergroundwater level has dropped significantly, especially in the desert lands. Therefore, it is necessary to use multi-stage turbo pumps, but these pumps need high power to be used when using deep wells, due to friction losses and losses resulting from the use of rotary bearing and shafts. These pumps are typically operated by electric motors.Which necessitates the presence of a source of electrical energy near the well, which is often not found in desert land. The present study investigates the pumps used to extract underground water from the deep artesian wells that have been used. recently due to the decline of the undergroundwater level resulting from the drought. The aim of the study was to develop these pumps in order to improve their performance and increase their efficiency, and thus reduce the energy required to operate these pumps. Where a hydraulic system was used to operate the pump and,dispense with the electric motors, as well as dispensing the rotary shafts and bearings, thus reducing the energy required to operate the pump. A practical study was carried out on a turbine pump with a well-known electric motor specification installed on an artesian well after the depth of the well and the level of the water surface were measured in the well. When the turbine pump was operated, the data required for the study was taken, then a developed theoretical model of the turbine pump hydraulics and under the same external conditions of the well. The specifications of the new model developed using the theoretical equations were calculated. When comparing the results obtained for the turbine pump that was installed and operated on the well with the results obtained for the theoretical model. The developer needs much less energy to run it to get the same discharge.
