A 200 kW hydroelectric generator requires a water pressure of 10 to 15 mV.
A hydroelectric generator is a machine that converts the kinetic energy of water flow into electrical energy. When designing and operating a hydroelectric generator, two major parameters, water height (difference in water level) and flow rate, are mainly considered. considered. Water height refers to the height to which the water falls, which determines the kinetic energy conversion capacity of the water to the turbine; flow rate refers to the amount of water passing through the turbine per unit time, which determines the power generated by the turbine; the generator. Therefore, for a 200 kW hydroelectric generator, the design head and flow rate should be determined, and the water pressure can be calculated based on the selected head and flow rate.
I would like to user tap water to connect a hydroelectric generator. What size hydroelectric generator can be used to charge the battery?
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 through one side of the slide, 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 pupower of 70% and 60% is 100 W. There is no need to invest more for 100 W.
The current to charge the battery is usually 5 to 6 amps. If you charge one 12 volt battery at a time, the motor power should be at least around 100 watts (the power reserve should be around 100 watts). considered), and it should be 12 Volts.
You can calculate it like this:
Water flow (kg/s) multiplied by the acceleration of gravity ( 9.8 Newtons/kg ) multiplied by the water impact height = power
Flow rate = the cross-sectional area of the pipeline multiplied by the flow rate and divided by the specific gravity of the water.< /p>
Generators of the same model are connected in parallel, as long as the combined power is sufficient.
Battery charging time depends on battery capacity and charging current .
