Abstract

Penggunaan pompa di dunia industri memiliki peran penting. Pompa digunakan untuk mengatasi perbedaan energi yang diperlukan untuk memindahkan fluida akibat dari perbedaan tekanan, perbedaan ketinggian, dan gesekan pada sistem perpipaan. Saat ini hampir 80% pompa sentrifugal digunakan dalam industri proses. Penelitian ini dilakukan untuk mengetahui apakah pengaruh outlet angle impeller pompa terhadap efisiensi kerja pompa serta bagaimana menggambarkan kurva karakteristik dan menentukan BEP (Best Efficiency Point). Pengujian menggunakan impeller backward 6 sudu dengan diameter inner 4 cm dan diameter outer 12 cm. Impeller memiliki inlet blade angle (β1) 20° dan variasi outlet blade angle (β2) 10°, 20°, 30°, 40°, dan 50°. Penelitian ini dilakukan dengan menggunakan tiga metode, yaitu eksperimen, perhitungan teoritis segitiga kecepatan, dan teoritis dengan menyertakan slip factors. Hasil yang didapat dari penelitian ini adalah dengan meningkatnya outlet blade angle akan menaikan nilai head. Kenaikan outlet blade angle juga akan menurunkan nilai BEP ke debit yang lebih rendah dan secara umum akan menurunkan nilai efisiensi. Berdasarkan hasil eksperimen, secara umum impeller dengan outlet blade angle (β2) 20° memiliki nilai efisiensi maksimum paling tinggi. Hasil penelitian ini juga dapat memprediksi head aktual dengan menggunakan analisis head teoritis yang melibatkan slip factor. =============================================================================================== The use of the pump in the industrial world has an important role. Pumps are used to overcome the difference in the energy required to move the fluid as a result of pressure differences, the difference in height, and friction in piping systems. Today almost 80% of centrifugal pumps used in industrial processes. This study was conducted to determine whether the effect of outlet angle pump impeller on the efficiency of the pump work and how to describe the characteristic curve and determine the BEP (Best Efficiency Point) . Tests using backward impeller 6 blade with inner diameter of 4 cm and outter diameter 12 cm. Impeller has a inlet blade angle (β1) 20° and variations of outlet blade angle (β2) 10°, 20°, 30°, 40°, and 50°. This research was conducted using three methods, namely experimental, theoretical calculations using a triangular speed, and theoretical include slip factors. The results obtained from this study is the rising blade outlet angle will increase the value of the head. The increase in outlet blade angle will also reduce the value of BEP to lower flow and generally will decrease the value of efficiency. Based on the experimental results, generally impeller with outlet blade angle (β2) 20° has the highest value of maximum efficiency. Results of this research can also predict the actual head using head theoretical analysis include slip factor.
