The price of a 300 W hydroelectric generator is around €600 to €1,000.
Hydraulic generator refers to a generator that uses a hydraulic turbine as the prime mover to convert water energy into electrical energy. As water flows through the turbine, the energy of the water is converted into mechanical energy. The rotating shaft of the turbine drives the generator rotor, which converts mechanical energy into electrical energy and produces it. It is the main electrical equipment for producing electrical energy in hydroelectric power stations.
How to make your own small 1000w high efficiency hydroelectric generator. The water level is not very high and the flow is very slow
51.02 cubic meters of water. 10 kWh = 10 kW × 1 hour = 10,000 Joules, flow = energy ÷ density ÷ acceleration ÷ square flow ÷ 2 = 10,000 ÷ 1,000 ÷ 9.8 ÷ (0.12/2) = 51.02 cubic meters, therefore 10 kilowatts of productionn hydroelectric power. The machine requires 51.02 cubic meters of water per hour.
It is difficult and unprofitable to make a small hydroelectric generator yourself.
To obtain high efficiency from a small 1000W hydroelectric generator, an impact hydroelectric generator set can be selected.
The impulse hydraulic generator set is also called horizontal hydraulic generator set. Like the oblique impact hydraulic generator, it is a hydraulic generator with high water head and low flow. The required water height range is: 7-40. meters. It is suitable for use in high mountain areas. Its working principle is as follows: in the hydraulic turbine, the jet coming out of the nozzle is not in the tangential direction, but in the direction forming a certain angle with the plane of rotation of the It enters the bucket from one side ofslide, then exits through the leaf of the bucket on the other side. The main features of the impact hydroelectric generator set are:
1. Under normal water conditions, water resources can be reasonably used to generate electricity.
2. If there is a rainy and dry period and there is no water, the diesel engine can be used to generate electricity.
For a small hydroelectric generator of about 1 kW, the market price is about 1,000 yuan. It is much cheaper and faster to buy it directly than to make your own.
For small hydroelectric generators of around 1 kW, the most important thing to consider is its operational stability and reliability. It is recommended not to think too much about efficiency. After all, for a unit with a power of 1 kW, the difference between the power of 70% and 60% is 100 W. There is no need to investir more for 100 W.
