Installation instructions
1. Installation requirements: The bottom surface of the turbine must be in close contact with the foundation plane, without tail water splashing and leakage.
2. Installation procedure: After the foundation of the unit with concrete is solidified, install the unit in place, and then pour the fixed unit. When installing the unit, ensure that the unit is fixed in a horizontal position. The gap between the unit and the ground is sealed with cement, and no water seepage is allowed. After the unit is installed, turn the runner shaft of the turbine by hand, and the runner shaft should rotate flexibly.
3. The basic requirements for installing pipes: purchase pipes according to the pipe diameter required by the unit, and the pipe diameter cannot be reduced. The pipeline should be bent as little as possible, and the angle between the pipeline and the horizontal should not be less than 25 degrees, otherwise the pipeline will grow, the head loss will be large, and the power generation will be insufficient. The water inlet of the water diversion pipe installed in the front pool wall is best to use a horn tube. The distance from the bottom of the pool is not less than 0.2 meters, and the inner diameter of the joints should be equal. In order to reduce the head loss, the joints should be minimized.
4. The installation of steel pipes: micro-hydropower mostly uses welded steel pipes with flanges. When installing, the flange rubber gasket must be placed in the correct position to avoid reducing the cross-section of water. The pipe joint nuts should be tightened in diagonal order.
5. Pier: At the junction of the water diversion pipe and the nozzle of the turbine, the pipe bears the greatest pressure, so a pier must be built with stone or concrete to fix the metal pipe.
6. Support: Due to the weight of the metal pipeline and the weight of water, the pipeline is too long and easy to bend and deform, so a buttress must be added in the middle. The location of the branch pipe is best set at the joint of the pipeline.
Valve installation
The valve is installed on the diversion pipe, the end close to the unit, about 1 meter away from the nozzle or directly on the nozzle, depending on the specific situation. The valve diameter of micro-hydropower should be the same as the diameter of the water pipe. Gate valves or ball valves can be used. Stop valves must not be used, because the selection of stop valves will reduce the cross section of the water and affect the output of the turbine.
Two points must be paid attention to when installing the valve:
1. The center line of the turbine runner shaft and tailpipe must be kept on the same vertical line.
2. Flange gaskets should be upright and bolted tightly connected, so as to reduce head loss and prevent leakage.
