What is the distance between the screws of the wind power generation base?

Introduction The distance between the screws of the wind power generation base is 400~600mm. The screw spacing of wind power generation base is generally required to be 400~600mm. The specific requirements need to be determined according to the actual construction.

What is the distance between the screws of the wind power generation base?

400~600mm.

The screw spacing of the wind power generation base is generally required to be 400~600mm. The specific requirements also need to be determined according to the diameter and height of the water-stop screws used during the actual construction process.

The screw pitch is actually the pitch. Pitch, the axial distance between corresponding points of two adjacent teeth on the thread.

How much does it cost to dismantle the base of a wind turbine?

As of the end of August 2012, China General Nuclear Power Group has completed the construction of the Yaboji Wind Farm Project in Longwan Town, Luoding City. A total of 427 million yuan has been invested, and it is expected to be completed and put into production in 2013. As of the end of August, a total of 427 million yuan has been invested in the project, and 55 million yuan has been invested this year, accounting for 50.6% of the annual plan. Among them, the construction of a 1.2-kilometer road from Rongmu Village to the booster station and the leveling of the booster station site have been basically completed. The excavation of 4.9 kilometers of access roads up the mountain has been completed, and the construction of temporary construction facilities on site has been 100% completed. Longwan Town actively cooperates with the project land and road widening to clear obstacles for project construction. At the project construction site, we can see that several wind turbine bases with a diameter estimated to be more than 5 meters have been transported to the foot of the mountain. Shipping vehicles are shuttled back and forth at the booster station construction site, and excavators are busy. According to the cadres of Longwan Town, there are 33 wind turbines installed on the mountain, each with a height of 70 meters and a wind wing diameter of 80 meters. After the project is completed, Yapoji Mountain will add a spectacular scene.

At the same time, this project is located in a relatively cold place with a pleasant scenery. It is expected to become a good place for leisure travel in the future.

Do the fans have high voltage fans and low voltage fans?

The cost of dismantling the base of a wind turbine is about 250 yuan/kw. According to relevant public information, the lifting cost of dismantling a wind turbine base is 150-200 yuan/kw, the transportation cost is also approximately 130 yuan/kw, and the dismantling cost is 20 yuan/kw.

Low voltage and high voltage refer to the driving motor of the fan and have no direct relationship with the fan. Smaller motors are driven by 380V power supply, while many high-power motors are designed to be driven by high-voltage electricity, which are so-called high-voltage motors. The current passed by a high-voltage motor with the same power is much smaller than that of a low-voltage motor, which is beneficial to the heat generation and service life of the motor. Some people want high-voltage electric drive. I guess they want you to change the original 380V motor of the fan to a 6000V high-voltage motor (the original 380V motor cannot be driven by high-voltage power supply). If your factory's motor is outsourced, There should be no difference between a low-voltage motor and a high-voltage motor for you. As long as the high-voltage motor you replace has the same speed and power as your original 380V motor, it has nothing to do with the fan. However, it is not ruled out that the journal and center height of the high-voltage motor may be different from the original 380V one.When manufacturing and installing your fan, you may need to change the size of the fan hub shaft diameter hole (perhaps the hole diameter of the belt pulley) and the height of the motor base.
