Buffering is to coordinate the data transfer between devices with vastly different throughput speeds. The application of buffer devices is extremely widespread, even becoming an essential part of certain industrial products, such as industrial fans. As we all know, industrial fans have put a lot of effort into safety, such as secondary protection at every connection, the use of balance correction technology, and unique fan blade designs. So why do industrial fans need to use buffer devices again?
First, it is still the safety issue we mention every time. During fan operation, sudden power outages and improper use can cause risks such as sudden stops and impacts. To better ensure the safety of the fan, a buffer device is added. In the event of sudden power outages and abrupt stops, the buffer device will unload most of the axial and centrifugal forces generated by inertia. When the fan is impacted, it will absorb the impact force produced by the impact to ensure that the blades and the entire fan will not rupture and fall.
Secondly, in order to ensure the efficient operation of large industrial fans, the buffer device will make the blades float differently due to the different rotation speeds during fan operation. As the blade angle can be adjusted according to the rotation speed and the on-site environment, it avoids the various forces brought by rigid connections being directly transmitted to the motor. The force on the motor is proportional to the output power. According to actual tests, industrial fans with buffer devices are 40% more energy-efficient than those with rigid connections. The blade float will also make the fan's outlet expand outward in a cone shape, increasing the coverage area and making the wind more uniform.
Finally, using a buffer device can extend the service life of industrial fans, which is very beneficial to customers. With a buffer device, the force on the motor is reduced, which will first reduce the motor load and increase its service life. The EPDM rubber used by manufacturers such as Amberma, which is independently developed and proportioned, has excellent heat resistance, aging resistance, corrosion resistance, friction resistance, and good sealing performance when used in fan buffering. It has been proven that it can be used for at least 10 years in normal use. In special situations, such as impact, frequent abrupt stops, and power outages, it can also ensure use for 5 years. The device is easy to replace and inexpensive. There are three screws on each side of the buffer, about 200 on the left and right respectively. You just need to remove the screws and open the cover to replace it directly.
Although the buffer device of industrial fans is a small rubber part, it is precise with it that the safety, efficiency, and service life of industrial fans has been further ensured. With it, industrial fans are a complete whole, a well-deserved "finishing touch".
