DESAIN MODEL TANGKI UNTUK MENGHEMAT KONSUMSI DAYA POMPA PADA SISI DISCHARGE

Abstract

This study aims to produce a prototype tank that is able to ease the work of the pump, especially increasing the pump head pressure (on the discharge side) so that it can save the input power of the pump up to the amount of power needed on the dischargenya side adjusted to the dimensions of the tank and buoy height. The research method used is development research with the following steps: (1) determining the definition of functions and specifications, (2) making a prototype tank model design to save pump power, (3) testing and simulating the performance of the design tank model. The test results show that the application of gravity on the liquid tank located at a certain elevation from the pump axis has a great potential to increase the pump's static head or can reduce power consumption on the pump discharge side up to 100% including losses on the discharge side by increasing tank capacity. Besides that, to obtain the effectiveness of the gravitational force used, the selection of buoyancy material and the thrust rod must be as light as possible.
