Effectively prolong the service life of large industrial fans

Effectively prolong the service life of large industrial fans
1. See if the industrial fan's motor head and the whole machine will jitter when the industrial fan rotates in the low-speed gear, the middle-speed gear, especially in the high-speed gear? At the same time, carefully listen to whether there are other abnormal noises (except wind noise) in the head part of the industrial fan motor? Is the noise of industrial fans within an acceptable range?

2. After the industrial fan has been rotating at high speed for a long time (at least 1 hour later), you can sense the heat generated by the front housing of the industrial fan motor with your hands or other devices. Excessive temperature rise of the motor during use can easily cause the industrial fan to stop rotating or burn the motor;

3. Look at the speed, power, air volume, noise and other parameters of the industrial fan (in theory, the speed, power, air volume and noise of the industrial fan are proportional, that is to say, the higher the speed of the industrial fan, the greater the power and the air volume. The greater the noise, the better the local ventilation and cooling effect. However, the measurement of speed, power, air volume, noise and other parameters of different brands of industrial fan manufacturers has a big gap. In fact, it is very different. It is difficult to make a horizontal and accurate comparison, and we can only feel it according to our life experience). However, with the advancement of technology, we can measure the power of different industrial fans with the help of a miniature power detector to compare which industrial fan is more power-efficient. For example: Germany Ai Miao DC variable frequency industrial electric fan YS-N189WF, its speed can reach 1450RPM, the power is only 90W, but the air volume has reached: 140m³/min, the noise is also very low, and the ordinary AC industrial fan of the same size has very little speed It can reach 1350RPM, but the power reaches about 180W, the air volume is about 90m³/min, and the noise is very high. In comparison, the German Ai Miao DC inverter industrial electric fan can effectively save more than 50% of energy!

4. Check whether the industrial fan stops intermittently when rotating the left and right swing heads at high speed, and whether the swing heads are not in place?

5. In terms of safety performance: Check whether the front and rear nets of the industrial fan adopt a dense net design, and whether the overall product structure is reasonable? (Industrial fans designed by dense nets have higher safety performance during use); ask if this industrial fan is equipped with an overheat protector. Will the industrial fan motor be automatically powered off when it accidentally gets stuck?

6. There are two types of industrial fan motor structures: fully enclosed and open. The high-end industrial electric fan adopts a fully sealed motor structure, which can prevent dust and other debris from entering the motor and adhering to the bearings, rotor and other parts. The motor runs smoothly and has a longer service life, while the open motor structure does not work. Therefore, the industrial fan with a fully enclosed motor is particularly suitable for use in cotton textile factory workshops or places with a lot of debris such as dust.

7. There are two types of industrial fan bearings: oil bearing and ball bearing. Ordinary industrial fans adopt oil-bearing bearings and need regular oil maintenance, otherwise the bearings will be severely worn and cause a lot of noise, and at the same time affect the life of the industrial fan. However, some mid-to-high-end industrial fans are designed with ball bearings. Like bicycle axles, they reduce friction through the rolling of balls, increase speed, extend the service life of industrial fans, and reduce a lot of trouble.

8. The materials of industrial fan motorsChina EC Blower Fans Manufacturers are copper wire, aluminum wire and copper clad aluminum. Non-brand industrial fans use aluminum wires or copper-clad aluminum motors with the worst heat dissipation performance. Industrial fans are most likely to burn when the temperature rises too high when the industrial fans are running at high speed. The high-end industrial fan must be a motor made of 100% regular copper wire and silicon steel sheet, which has the best heat dissipation performance, low temperature rise of industrial fan motors and long service life.

9. The materials of industrial fan blades include ordinary plastic blades, aluminum blades, iron blades, and ABS plastic blades. These four fan blade materials have their own advantages and disadvantages. However, it is recommended to use ABS plastic fan blades in many places, because the wind blown by it is very cool, natural and fresh, while the wind blown by aluminum fan blades or iron fan blades is very cool. It's hard and feels uncomfortable.

10. The front and rear housings of industrial fan motors are made of aluminum, copper and iron. The copper or iron front and rear shells of ordinary industrial fans have poor heat dissipation performance, while the aluminum front and rear shells of high-end industrial fans have much better heat dissipation performance than copper or iron ones, which effectively prolongs the service life of industrial fans.
