Özet:

 The goal in centrifugal pump designs is to achieve maximum efficiency. Even small percentage increases in pump efficiency provide high overall energy savings in pumps that operate for long periods of time, especially those that use high-power motors. While fan and casing structures are designed in line with this goal, many structural features affect the efficiency of the pumps. In the study, pump performance values of the 5 horizontal shaft centrifugal pump at different flow rates were measured in the laboratory. Depending on the change in pump flow rates, it was determined that the pump power consumption varied between 15-42kW and the efficiency values varied between 32.63-55.57. Considering the statistical compatibility of the measured pump performance values with the values obtained by CFD, it was determined that the coefficient of determination of the measured and predicted values varied between 0.870 and 0.936, which is quite high. The mean absolute percentage error was determined to be well below the acceptable value of 10.

 Santrifüj pompa tasarımlarında amaç maksimum verime ulaşmaktır. Pompa verimliliğindeki küçük yüzdesel artışlar bile, özellikle yüksek güçlü motorlar kullanan, uzun süre çalışan pompalarda yüksek toplam enerji tasarrufu sağlar. Fan ve gövde yapıları bu amaç doğrultusunda tasarlanırken birçok yapısal özellik pompaların verimini etkilemektedir. Çalışmada 5lik yatay milli santrifüj pompanın farklı debilerdeki pompa performans değerleri ölçülmüştür. Pompa debilerindeki değişime bağlı olarak pompa güç tüketiminin 15-42kW arasında değiştiği, verim değerlerinin ise 32,63-55,57 arasında değiştiği tespit edilmiştir. Ölçülen pompa performans değerlerinin CFD ile elde edilen değerlerle istatistiksel uyumu göz önüne alındığında, ölçülen ve tahmin edilen değerlerin determinasyon katsayısının oldukça yüksek bir değer olan 0,870 ile 0,936 arasında değiştiği saptanmıştır. Ortalama mutlak yüzde hatasının ise kabul edilebilir sınır değer olan 10un oldukça altında olduğu belirlenmiştir.
