STUDI EKSPERIMENTAL PENGARUH SEKAT SUDU BERPENAMPANG MANGKUK TUNGGAL TERHADAP DAYA DAN EFISISENSI TURBIN PELTON

Abstract

Increasing energy needs in Indonesia must be in line with meeting energy needs, therefore renewable energy-based power plants (EBT) need to be developed. one of them is the Pelton turbine which is included in the PLTMH, the selection of the Pelton turbine is based on a good level of efficiency. This study aims to determine the effect of insulation on a single bowl blade on the most optimal power and efficiency. This study used an experimental method by varying the baffle on the blade, namely, without baffle, one baffle and two baffle on the Pelton turbine. The number of blades is 8 with variations in water capacity of 0.001854 m3/s, 0.002005 m3/s, 0.002434 m3/s and 0.003114 m3/s using a nozzle with a diameter of 25.4 mm with a spray distance of 50 mm. Meanwhile, to get the power and efficiency of the Pelton turbine, a loading variation of 5 kilograms, 10 kilograms, 15 kilograms is used and continues to increase until it stops. This study produces maximum power at a single partition variation of 60.0896835 Watt at a water flow capacity of 0.003114 m3/s with a loading of 40kg and has a load resistance of up to 100kg. While the optimum efficiency for the unscreened variation is 76.97% at a water capacity of 0.001854 m3/s with a loading of 10 kg and has a load resistance of up to 22 kg.
