The functions and characteristics of industrial fans

Industrial large fans are widely used in high-rise spaces such as industrial plants, logistics warehouses, waiting rooms, exhibition halls, sports halls, supermarkets, etc., as a commonly used industrial machinery for space ventilation and personnel cooling. Compared with traditional HVAC and small high-speed fans, it has unparalleled application advantages. Industrial fans consume less power and have a higher air volume. A single fan occupies an area of up to 1200 square meters, making it a solution for ventilation and cooling in high-rise spaces.

Industrial fans continue to lead the innovation of industrial fans, and the innovation of permanent magnet brushless servo motors for industrial fans has the following advantages: variable frequency starting: in conjunction with domestic grade frequency converters, low-speed motion vibration is reduced, variable frequency starting has no impact, and motion is smooth. Sealed motor: Closed motor has fewer monitoring points, fewer fault points, and more maintenance times, greatly reducing costs and having a long service life. Aviation grade materials: The propeller blades are made of the same material as the aviation wings, with stronger toughness, safety and reliability, making them suitable for small helicopter propellers. Simulated natural wind: Streamlined fan blades, combined with aerodynamic principles, can strongly stir indoor air to produce simulated natural wind. Efficient and energy-saving: permanent magnet direct drive motor+top frequency converter, air volume can reach 15000m3/min, power consumption per hour is about 1KW, and the floor area can reach 1200m2.

So, since industrial fans are economical and practical, is installation particularly troublesome? Let me tell you, as professionals, installing industrial fans is as easy as installing ceiling fans at home: building structures include H-beams, I-beams, brick concrete square beams, ball column structures, etc. Due to the fact that industrial large cranes are driven by motors, bearings are important components of the machine and the core of rotating parts. Their large bearings are mainly used for oil bearings, which are generally powder metallurgy products. The lubricating oil inside is tightly packed in the bearing oil hole. When the large ceiling fan is running normally, the temperature of the motor can slowly rise. Due to the friction and heating between the shafts, the original lubricating oil will gradually be exhausted, so it is necessary to replenish it in a timely manner to maintain the normal operation of the industrial large fan.

Bearings play a very important lubricating role in industrial fan motors. If lubricating oil cannot be replenished in a timely manner, it will affect the normal operation of the fan. This is because the speed of large ceiling fans is too low or does not rotate, which makes dry running easy to burn out the motor and greatly reduces the service life of large industrial fans. At this point, it is necessary to inject some lubricating oil into the holes of the motor or use sewing machine oil. The total height of the building shall not be less than 4.5 meters; The safe distance between the fan blades and obstacles shall not be less than 0.2m; Input power supply: 380V/220V is acceptable. All production plants not only need to perform this maintenance on industrial fans, but also on other large equipment to increase their service life and reduce equipment failure rates.
