Bigfans adopts external clip type plug-in and aviation hard aluminum 7075 as aging heat treatment to ensure strength and toughness. Certified by the national quality inspection center, it has withstood more than one million fatigue experiments, and solved the problem of blade falling caused by long-term metal fatigue.
Special high strength aviation magnesium aluminum alloy is adopted, the surface is treated with fluorocarbon paint, and the aerodynamic blade shape is adopted. There are up to three sets of stiffener supporting system inside the fan blade, which can enhance the strength of the fan blade and completely avoid the sagging of the end of the fan blade and the fatigue loss of the fan blade to the connecting components. High strength alloy steel is inserted into the fan blade to avoid fatigue fracture of the root during long-term operation of the fan blade, so that the stress point (screw) expands to the surface stress.
When the motor is developed, NSGA optimization algorithm is used to balance the above performance indexes perfectly and achieve the highest cost performance, ultra-low torque ripple and high overall efficiency. Super large torque reaches 300N · m, providing stronger and more stable driving force. Choose customized high-performance magnetic steel, never demagnetize. Super efficient heat dissipation system can give full play to its super performance without overheating and affecting its service life.
The application of protection grade in industry is generally IP66. The control box adopts airtight design, which greatly improves the service life of electrical components and is more safe and reliable:
1-dust proof grade to prevent harmful dust accumulation.
2-water resistant liquid splashed on the shell from any direction has no harm effect.
3-whether negative pressure is applied can be selected during detection. The negative pressure is the same as ip6x. To extract air from the inside of the product and generate negative pressure!
4 - simulated rain environment, 360 full-scale rain!
5-The splash proof type is not affected by water splashing in any direction
6-anti spray type directly affected by water spray in any direction without harmful effect
