Vertical axis wind turbines are seen more and more in cities, especially in the wind-solar complementary street lights and urban monitoring systems. Many of the wind turbines used are vertical axis.
What are the advantages of vertical axis wind turbines?
1. Long life, simple installation and easy maintenance. The blades of the vertical axis wind turbine rotate in the same direction as the inertial force and gravity, so it is not easy to produce mechanical fatigue and increase its service life. When the equipment is installed, it can be placed far below the wind wheel or even on the ground, which is convenient for installation and maintenance, and also reduces the safety problem of workers climbing and the cost of lifting equipment.
2. Low noise has no impact on the surrounding environment. It is very important that vertical axis wind turbines can be widely used in cities. Noise control is very important. The tip speed ratio of the horizontal axis wind wheel is generally very small. The aerodynamic noise is very small, and it can even achieve a mute effect, and its appearance is beautiful, and its small blade rotation radius is not harmful to birds.
3. There is no need to configure the yaw-to-wind system, the wind from any direction can drive the vertical axis wind turbine to work normally, and the main shaft will always rotate in the design direction, so its structure is much simplified, and the movable parts are also compared with the horizontal axis. There are fewer wind turbines, which not only reduces the production cost but also reduces its failure rate, and improves the reliability of later use.
The above are 3 of the many advantages of vertical axis wind turbines. For more advantages, you are welcome to call and discuss in detail with us.
