Özet:
ABSTRACTTHE SURVEY OF THE PERFORMANCE OF SERIES AND PARALLELCONNECTED CONTRIFUGAL PUMPS IN DIFFERENT ROTATIONAND TEMPERATUREKeywords: Performances of centrifugal pumps, experiments of the performances ofcentrifugal pumps depended on temperature.In this survey, the performances of series and parallel connected centrifugal pumpswere experimentally carried out in different rotations and different water temperatures. Then,pressure depended on volume flow, delivery head, efficiency, power characteristics wereinterpreted with the instruments of graphics and tables.Experimental works were conducted in the HM 330 test rig which is in the FluidMechanic Laboratory in the Department of Machine of the Faculty of Technical Education. Inthe test rig, a cooling unit was joined in order to obtain varied water temperatures.This experiment were performed in six different temperature, which are 25, 20, 15, 10,5, 1 oC and in four different rotation, which are 800, 1200, 1600, and 1900 rpm. Inexperiments, the values of pressure, rotation flow, efficiency, and power were experimentallyrecorded by adjusting the ball-cocks with angles to 0Â° , 45Â° , 75Â° , and 90Â° when centrifugalpumps were connected series and parallel. In this survey, finally, the gained data weregraphically interpreted.This study that is named the survey of the performance of series and parallelconnected centrifugal pumps in different rotation and temperature includes 56 graphics and 48tables.Temmuz 2006 Cemalettin GEÇ T
