Eksperimental Optimasi Tipe Lekuk Sudu Pada Pompa Difungsikan Sebagai Turbin Untuk Pembangkit Listrik Tenaga Picohidro
Abstract: This study
emphasizes the experimental pump functioned as turbine (PAT) by modifying the
angle of entry and exit on the PAT blade. A pump for paddy NS-50 pump with a
capacity of 563.22 litre/ minute and head 20 m tested in the laboratory of the
Sebelas Maret University of Surakarta to obtain specific round figures. In this
study the variables used are head (H) is 4 metre and the angle variation of the
blade entry and exit totally 7 different specimens as well as variations in the
shape of the blade is rectangular, round and oval. Pumps as turbines then
connected to the generator and the result is electric power. Result of the
research showed that the best variation is at the variation of the angle
outgoing and incoming angles of 30/30, the rotation happens is 850 rpm and the
generated power is 90 watts. The results of the experiments showed good results
theoritically. It is suggested to further modifications by using the same pump,
expected better results in order to achieve the best efficiency point of PAT.
