TAGUCHI AND RSM BASED OPTIMIATION OF ENERGY CONSUMPTION ON INTERNAL GEAR PUMPS

Abstract

Internal gear pumps are used in a variety of applications for the transfer of many different types of\rliquids like fuel, oil and food in both the industry and daily life. The R & D studies for the efficiency\rof pumps carried out worldwide account for 6% of the total, and thus energy savings of 303 trillion\rBTU can be achieved annually. With minimum energy consumption, high rates of energy savings will\rbe ensured by transferring maximum amount of fuel. For this purpose, firstly a detailed literature\rreview was made, and then industrial pump manufacturers and scientific studies were investigated. As\ra result of that, a new type of internal gear pair design ,which has not been manufactured so far in the\rindustry, has been proposed. In the new pump, the effects of tooth length and the changes in the\rnumber of revolutions on flow, power and SEC results were studied. Thus, it will be possible to\rcompare energy expenditure and flow rate with the other pumps developed. By using Response\rSurface Method (RSM), “Taguchi Method” and “Anova Variance Analysis”, optimum speed and tooth\rlength were determined as 700 RPM for speed and 85 mm for tooth length by taking SEC S/N graph\rinto account. In this way, pump production with optimum flow rate and energy consumption amount\rin the industry was produced, and the energy consumption value was decreased during the fuel transfer\rfrom 156,1 Wh/m3 to 92,0 Wh/m3.In addition, the change in the flow rate was found to be the most\reffective parameter in the 83% rate change.
