The large industrial fan has brought a cool breeze to the workshop, warehousing and logistics. Now other tall spaces, such as bus station waiting rooms, indoor basketball halls and other places are in use. Now there are many large fans with similar external shapes but different internal structures on the market. In fact, they are still very particular.
Industrial Large Fan Oversized Industrial Fan
First of all, safe production is above everything else. No factory can guarantee uninterrupted power outages, and no manager can guarantee that employees will operate in full accordance with the instructions.
When a large industrial fan using a geared motor encounters a sudden power failure or power failure, the reducer will directly lock up, but the fan will continue to run at this time, so the cutting force formed by the fan blade and the blade handle will continue to cut the bolt, which will last a long time. The cut bolts will be loose, and the large industrial fans that use bolts to fix the fan blades and leaf handles alone will have the phenomenon of fan blades falling off or falling, which is very dangerous. The tenon and mortise will be automatically locked, and the fan blade will not fall.
mortise and tenon structure
When the industrial large fan using permanent magnet synchronous motor encounters a sudden power failure or power failure, the above situation will not occur, and its interior will slowly rotate until it stops, and there will be no sudden occurrence of the fan blade and the blade handle to the bolt. Cutting force, there is no danger of fan blades falling.
Geared motors and permanent magnet synchronous motors are two commonly used motors in the industrial large fan market. The service life of geared motors is usually 1-3 years, and the service life of Dawang ventilation series permanent magnet synchronous motors is usually more than 10 years. . The gear motor contains gears, which will cause friction loss, so the service life is short. There are no reducers, gears and other components in the Dawang ventilation series permanent magnet synchronous motor that will cause friction loss, so the service life is long.
Gearmotors and Permanent Magnet Synchronous Motors
Friction will also lose power. Therefore, the energy efficiency of the geared motor is only about 78%, which belongs to the third-level energy efficiency, while the energy efficiency of the Dawang ventilation series permanent magnet synchronous motor can reach more than 95%, so the energy saving can be increased by 30%.
Safety and energy consumption are two important factors considered by users of industrial large fans. These two factors also form the difference in price. Only products that are safe and energy-saving can adapt to the general trend of market development and meet the needs of use. users' needs.
