| Popis: | Voltron, a locally designed water pump, is widely used among farmers in Central Luzon of the Philippines. The study aimed to evaluate the performance of the Voltron water pump. Voltron was tested at different pump shaft speed settings of 450, 600, and 700 rpm and with different blade (impeller vanes) numbers of 6, 8, 9, and 10 using V-belts and B-section pulleys transmission. The highest pump efficiency of 62.5% was observed using an 8-vane impeller under a 700-rpm setting. Currently, farmers utilized the 8-vane impeller under a 600-rpm setting. Statistical analysis showed that there is no significant difference between the pump efficiencies on the set pump shaft speeds, but there is a significant difference in the set number of vanes. On the other hand, the effects of pump shaft speed, the head, discharge, and fuel consumption increased as rotational speed was increased. The difference is around Php 17.61 per ha per day of operation favoring the usual setting upon the computation of the fuel cost. However, the 8-vane impeller under a 700-rpm setting will be more economical in the long run as it is determined to be more efficient than the normal setting being used by the farmers. |
