The radial flow hydroelectric generator set is composed of a water turbine and a generator through a coupling. The water turbine is mainly composed of a volute
Composed of shell, impeller, main shaft, seal, suspension, bearings, etc. During operation, the water flow is affected by the working head,
Through the water intake pipe to the inlet of the water turbine, it enters the volute to impact the rotation of the impeller, and the main shaft drives the generator to work.
There are two types of generators: permanent magnet generators and excitation generators. The rotor of permanent magnet generator is made of permanent magnet material
Yes, the output voltage is unstable and fluctuates greatly with the speed, making it unsuitable for household use. Excitation generators are divided into brush excitation and
There are two types of brushless excitation, and brushless excitation generators require regular replacement of carbon brushes. The excitation generator is equipped with an excitation system,
No additional starting device is required to generate electricity for operation. Our company's excitation generators are all equipped with voltage regulators (AVR)
The output voltage is relatively stable.
The horizontal runoff split hydro generator unit has the following technical advantages:
1. Pipeline inlet and outlet are convenient for installation, use, and maintenance;
2. Separation of water turbine and generator for easy maintenance and replacement of vulnerable parts;
3. The water turbine has 2-3 separate bearings, while the generator has 2 separate bearings, ensuring a reliable structure;
4. The water turbine has an independent oil lubrication system, resulting in a longer bearing life.



Water source determination
The construction of a micro hydropower station is carried out in areas with a certain water flow drop, by collecting small stream water and entering it through a water diversion pipe
The water turbine generator set in the computer room is driven by the water flow to rotate the turbine wheel, thereby driving the generator to generate electricity. Jianweishui
The power station first needs to determine the head and water volume of the water source, and calculate the starting electricity based on the measured head and water volume.
Measurement of water head
Mao Shuitou: refers to the vertical height difference of the water level upstream and downstream of the water source. The usual measurement methods include:
1. The pressure value can be measured by installing a pressure gauge at the end of the pipeline and closing the valve to measure the pressure value
It's just a rough head; 2. Measure the water level difference between upstream and downstream using a water level gauge; 3. Measure through GPS and other technical means.
Net head: Net head refers to the pressure that a water turbine can effectively utilize.
Measurement: Open the valve and measure the pressure displayed on the pressure gauge installed on the inlet pipeline during the operation of the water turbine
It's the net head.

Measurement of water volume
1. Cross-sectional area method
The flow rate is equal to the cross-sectional area multiplied by the water flow velocity. Measurement of the cross-sectional area of a canal, such as the width of the canal
Roughly calculate the cross-sectional area A. To obtain more accurate measurements, the cross-sectional area of the ditch can be segmented and measured separately
The small area is then added up to obtain the total area.
The measurement of water flow velocity can directly throw a floating object on the water surface and observe it drift for a certain period of time
Calculate the displacement that flows through it within one second, which is the flow velocity of water.
2. Volumetric method
Use a bucket to collect water, measure the time t required to fill the bucket, and then weigh the water inside the bucket
The weight W is obtained by dividing the weight W of the measured water by the time t to obtain the water flow rate Q. When estimating traffic, it is necessary to do so multiple times
Measure the average value while considering the seasonal variation of water volume.
Determination of Reservoir
The main function of the inlet water tank is to precipitate impurities and store water. There is no specific standard for the size of the pool, depending on the terrain on site
The bigger the better. The inlet pipe should be installed in the middle of the reservoir to prevent floating debris and bottom sediment from entering the inlet
Water pipes. The bottom of the reservoir should be equipped with a sewage pipe and cleaned regularly.

Selection of pipe diameter
The installation of the water supply pipe should not leak water, and the material of the pipe fittings needs to be determined by the user based on pressure, installation convenience, cost, etc
Select factors and purchase locally. If the drop is 100 meters, the actual water pressure is 1.0Mpa, and the pipe
The actual pressure should be above 1.0Mpa.
The recommended minimum installation pipe inner diameter in this sample is when the pipe length is not greater than twice the water head
Recommended. Because there is pressure loss when the water flows through the pipeline, the thinner the pipe, the faster the water flow rate, the greater the pressure loss, and the smaller the net head, resulting in a smaller power generation of the generator. Therefore, if the pipeline is too long, when selecting a pipeline,
Try to choose a larger inner diameter of the pipe. Many customers are concerned that the water intake pipe may not have enough water, which is unnecessary. Because using
The water volume is mainly determined by the water turbine, and the water pipe only serves to divert water. The adjustment of water volume can be achieved through an inlet pipe
The valve on the road will be used.
When installing pipelines, the water intake pipeline should be as smooth as possible, avoiding turns, right angle bends, upward warping, etc. as much as possible
Reduce hydraulic losses and increase power generation.
