Loosen the screws that fix the belt pulley, take out the belt pulley, adjust the casing, take out the stator, use a felt to feel the copper on one side, and then use a fork to cut out the copper on the other side, take out the rotor and lay it out. Brass fan blades on both sides will do. Generator, which plays an important role in generating electricity in automobile components, often fails to generate less or no electricity during use, making it difficult for the car to start. At this time, the automobile generator needs to be replaced.
Advantages of Geely Auto Borui
The appearance of the car is beautiful and majestic. The wheelbase of 2.85 points brings a large internal space, and the interior materials are full. , soft materials and chrome decoration bring a strong sense of luxury. Comfortable, as a domestic mid-size car, Borui's current market performance illustrates Geely Automobile's sincerity in the Borui car. The double-wishbone front suspension is completely conscientious compared to the MacPherson or multi-links of joint venture cars of the same level.
Some friends say that Borui's shock absorbers are not good, but I think it is a matter of opinion. If you compare Borui with high-end cars, Borui may have many shortcomings in many places, but Borui is only a family B-class car under 200,000. You can definitely compare joint venture cars under 30 with Borui. I believe Borui's performance will be quite outstanding. In terms of sound insulation, Borui has done quite well.
How are the blades of wind turbines determined?
The deformation of the fan blades on the rotor of the hydroelectric generator will have the following effects on the generator.
1. The motor cooling fan blades are broken, and the motor cannot dissipate effective heat. The temperature rise increases, the motor becomes hot, and the insulation aging in the stator is accelerated.
2. If the fan blades are partially damaged, it will cause unbalanced operation, the motor will vibrate, and the stability of the machine base will be damaged.
Please don’t copy and paste so much. The key is whether the pasted content is relevant. LZ is asking about wind turbine blades, not the impeller blades of compressors as you mentioned.
The blades of the wind turbine are determined based on factors such as the design rated power of the wind turbine, the rated wind speed of the wind turbine, and the density of the local wind.
If the impeller diameter of a wind turbine is D
Then its swept area S = ∏D^2/4
The area passed through per unit time The mass of the wind, that is, the wind flow rate is Q = ρSV = ρ∏VD^2/4 V is the wind speed
According to the kinetic energy theorem, there is wind power density
P1 = 0.5mV^2 = (ρ∏VD^2/4)V^2/2 = ρ∏D^2*V^2/8
Then there is a wind power coefficient Cp, which is the wind power coefficient Cp obtained by the wind wheel from Ek The percentage of wind energy that can be captured accounts for the total wind energy
Therefore, the theoretical power generation of the wind turbine
P = Cp*P1
And the wind turbine is designedBefore long-term observation of the wind speed and air density in the wind field is required, the design wind speed V and air density ρ must be obtained. The design Cp is related to the tip speed ratio, and the optimal value is generally selected. Therefore, the required theoretical diameter of the impeller can be back calculated.
