Abstract: Aiming at the environmental pollution problem caused by the dry batteries used in the induction faucets, a new type of micro-pipe turbine was designed and developed. The shape and size of each flow component was determined preliminarily, the multi-objective optimization orthogonal test was carried out on the turbine, the optimal test scheme was determined, and the physical model expe-riment was carried out. The interaction between the water flow and the turbine transmits rotating mechanical energy to the generator, and generating the electric energy used by the water faucet. Based on the orthogonal experimental optimization theory, the turbine output under the design flow rate is 6.30 W, which is 32.35% higher than the preliminary design scheme, and the efficiency is 85.13%, 2.58% higher compared with the preliminary scheme. After the optimization, both the turbine output and efficiency meet the design requirements. The range difference results show that the turbine output first increases and then decreases with the increase of the number of blades, increases with the increase of the number of fixed guide vanes, decreases with the increase of the opening of fixed guide vanes. The ma-ximum output of symmetrical guide vanes was achieved. The turbine efficiency increases with the increase of the number of blades, and the number of fixed guide vanes, increases first and then decreases with the increase of the opening of fixed guide vanes. The negative curvature guide vanes has the highest efficiency. The research results provide a reference for the design and optimization of micro-pipe turbines.
