1. How about noise of this wind generator?
The sources of sounds emitted from operating wind turbines can be divided into two categories:
1) Mechanical sounds, from the interaction of turbine components.
2) Aerodynamic sounds, produced by the flow of air over the blades.
Our mechanical design, like double bearings; front-back faces; exceptional blades assemble and anti-vibration plastic pad connection with pole, blades design and materials, all these contribute to make IDEAL400 the quietest wind turbine in the world.
2. Is it anti-corrosion in marine condition?
The body is made of a lightweight magnesium and aluminum alloy, and coated with a marine-grade polymer powder coat to prevent oxidation or corrosion.
Our latest study found that in order to anti corrosion for a long time, we follow these steps:
(1)Surface polishing
(2) Zinc-aluminum coating treatment
Zinc-aluminum coating is composed of ultrafine zinc and ultrafine aluminum and none-chrome mental salt, it is a non-electrolytic inorganic coatings. After the treatment, the coating form an anti-corrosion surface of inorganic zinc sheets and aluminum flake. No organic solvents, non-toxic metals (such as nickel, lead, barium and mercury) and Cr, so more environment friendly.
(3)Sandblasted
(4) Using two layers of epoxy powder painting. Most manufacturers adapt single epoxy powder coating , a thin layer painting, surface porosity, or painted surfaces damaged during installation, these will lead to corrosion, our double epoxy coating is approved to be a good solution to this corrosion issue.
3. Why we use 3 blades in this IDEAL400, IDEAL600 wind generator, and 5 blades for IDEAL2000 wind generator ?
Many scientific experiments show that 3 blades and 5 blades wind generator have a good wind power coefficient. For small size wind turbine, as it is relative high rotate generator, thus in order to get a good output in high wind conditions, we use 3 blades for IDEAL400 and IDEAL600. Besides, three blades wind turbine enjoy a better rotate balance, and output power is more reliable.
