Knowledge of small hydroelectric generators

If the height difference H=10 meters, the internal diameter of the pipe is 10 centimeters and the flow rate is assumed to be 5 meters/second, then

Flow rate Q=V (3.14 D^ 2/4)=5* (3.14 *0.10^2/4) = 0.03925 cubic meters/second

Water flow power

P = 9.8QH = 9.8*0.03925* 10 = 3.85 kilowatts,

Considering the efficiency of the turbine and generator, let's generate 2 kilowatts of electricity! Available to a farmer.

But such a small hydroelectric generator may not be available.

What are the power models of small silent diesel generators?

The national standard for gasoline generators is to generate 270 grams of gasoline per kilowatt hour.

At full load, the fuel consumption of 1 kW per hour is 1*0.27 = 0.27 kilograms. Converted to liters, it is as follows: the weight divided by the specific weight of gasoline 0.722 is equal to 0.374 liters. i.e. at full tankge, a 1 kW gasoline generator consumes 0.374 liters of fuel per hour, which is 0.374 times the capacity of 5 kW.

The oil change interval for small domestic gasoline generators is 220 to 250 hours or one month. If Category 2 engine oil is used, the engine oil life can be extended up to 400 hours before changing, but the oil filter (filter element) must be replaced.

Replacing the generator oil can well guarantee the stable use of the generator set, which also effectively extends the service life of the generator set to a certain extent, so it must be accurate when the use of the generator. . Determine the engine oil change time.

Detailed information:

< p>The noise of gasoline generator set has broadband spectrum characteristics, and the equipmentmuffler ent must withstand high air flow speeds, high temperatures and pressures, and is not afraid of water and humidity. When the temperature increases, the. the performance of the silencer does not change much. According to In this case, composite silencers with micro-perforated plates are often used in management.

Using a thin steel plate of 0.5-1mm, it is made into a double-layer micro-perforated plate silencer with a hole diameter of 0.5-1mm and a perforation rate of 1% to 3%. protection against medium and high frequency noise absorption effect. When there are several layers, the thickness of the cavity depends on the absorption frequency band. When the low frequency is 125-250 Hz, the cavity thickness is 150-220 mm. When the average frequency is 500-1000 Hz, the cavity thickness is 80-120 mm.
