Internal coil: pure copper coil. The generator drop requires 5-15 meters, and the drop is calculated based on the vertical height. The pipe diameter requires 75 mm pipe diameter.
The water volume requires a full pipe. The generator needs to meet the above requirements in order to be full. The inlet and outlet of the generator is 50mm, which can be connected to the pipeline, and the sound is relatively small. A large bucket or pressure tank is required upstream, or the upstream water pipe must be larger than 80mm. There is no need to repair the pressure tank.The generator has a sealing ring. The impeller is relatively tight. The main function of the seal ring is to protect the bearing and the generator. The bearing of the generator without the seal ring is more prone to damage. The bearing is not durable and the generator coil will burn when water enters.
The seal ring is installed. The disadvantage is that the friction is large.
