Axial-flow Hydroelectric Generator For Household

Axial-flow small hydroelectric generators are mainly used in places where the water drop is relatively low, such as small rivers, small dams, etc. The axial flow types small hydroelectric generator is mainly composed of a generator and an impeller coaxially. Working principle and installation method: First, plan the installation site. Generally, it is relatively firm to install and build next to or where there are rocks underneath. Use concrete and stones to build the water intake channel; use wooden planks to make an open and close sluice; use wire mesh as a garbage baffle to form the water intake system. Use concrete and stone to build a spiral flat water channel according to the model, so that the water forms a vortex and drives the impeller to rotate. A horn-shaped draft tube with a small upper surface and a larger lower surface is built under the spiral plane. The main purpose is to allow water to form a suction force in it to draw the impeller downwards, thereby generating strong power to drive the generator to work. Therefore, the power of the generator mainly comes from the draft tube. The length of the draft tube is the drop of the water flow, which is called the head. Small axial-flow hydroelectric generators generally work at a head between 1 meter and 6 meters.
