Variasi Sudut Pemasangan Tabung Kompresor Terhadap Unjuk Kerja Pompa Hidram

Abstract

Water is one of the factors which very important and necessary in the life of living creatures. Therefore, water must be available whenever and wherever in the quantity, timing, and sufficient quality. Hydraulic ram pump is a pump which does not require external energy as the power source. The purpose of this research is to understand the influence of the mounting tube compressor with tilt angle from the water weight-lift of output pipe. This research uses hydrant pump with a dimension of the compressor of 3 inches (in diameter) and 60 cm (in height). The falling angle of the pump is 35°. The falling-height is 2 meter with 4 variations of weight-lift 4, 4½, and 5 meters. The method of analysis is conducted by analyzing data obtained in the experiment, while the results are presented in the form of tables and graphs. The results of the research shows that the best volumetric rate output is about 0.035 l/s at the mounting tube compressor of 90° and 4 meters water weight-lift, while the lowest volumetric rate output is 0.011 l/s at the 5 meters water weight-lift. The best efficiency is 27.3% at the mounting tube compressor of 90° wi th 4 meters of water weight-lift, while the lowest efficiency is 6.5 % at the mounting tube compressor of 90° and the 5 meters of water weight-lift.
