This 50mm pipes of this generator can be used as the instruction reference, all According to the actual test, the vertical drop is taken as the standard, the length is not used as the reference, and the vertical height is taken as the accuracy, Your vertical height is 10 meters, the drop length is 30 meters, but the drop is only 10 meters, you said your pipe is 100 meters and 200 meters use, because there is no water pressure impact force without vertical fall height, the water volume is required to be 50mm pipe through the water pipe to fill the pipe, fall. Different height difference power generation is different, taking 1000W micro hydroelectric generator as reference, vertical drop is about 3 meters Can send 10W to 20W, 10 m can send 100W to 300W, 15 m can send 300W to 500W, 20m can send500W to 700W, 30 meters can send 700W to 1000W, this is based on the vertical drop as the standard, not Please follow the instructions for your length, installation and use of the generator. The generator outlet is connected to a drain pipeMeasure the farther the water is, the better. Connect the pipes around the generator. Don't let the water fly everywhere. Use plastic to drain the water. Wrap the bag or electric tape, cover the generator head with things, and put the generator in the place where the rain water can't soakPay attention to the connection of all lines, and do not encounter electric short circuit. The quality of the generator is guaranteed for 3 years. The water inflow short circuit is not guaranteed, and the water inflow short circuit is not guaranteed.It is the problem of personal installation and use that has nothing to do with the manufacturer. You should install and maintain the water pipe, connect the leaking and spraying place, and connect the lineAll the roads are connected, and all these things will not happen. Please use them strictly according to what we said, important thingsThree times, connect the water pipe to the outlet, connect the drain pipe to drain the water further, you can buy a sewer drain pipe The PVC type is used to connect to the generator outlet. The generator's outer warp should be larger, and it can't be plugged in directly. Use fire to bakeTake a look at the PVC joint, use fire to soften the plastic joint, and then you can put it in naturally. After putting it in, use AB glue Seal the gap, the generator only needs to pay attention to the waterproof work, other don't need to care about it.
