1. Air flow: a large area of breeze blows to achieve natural three-dimensional air flow;2. Suitable for four seasons: strengthen the environment ventilation, cool in spring and autumn, and comfortable in summer and winter;
Wheel hub-the mother of large fan safety, continuous improvement of the hub connection mechanism to ensure the safety factor of the whole machine, safety guarantee
Super-hard aluminum alloy + precision high-pressure forging technology (& sigma; b up to 570Mpa) + T6 heat treatment process + CNC precision processing means + dynamic balance full inspection quality, using the current domestic anti-disc and hub cover assembly, currently a domestic upper and lower chassis Combined with the safety issue of fixed fan fins, at the same time reducing the weight of the whole machine and improving the efficiency of the motor to achieve a perfect combination. The anti-disengagement adopts the installation method of tightly connecting the lower part and the hub, which improves the current anti-disconnection connection racks on the market. There is a certain risk of unexpected operation:
1) Reliable life design of 40 years;
2) 10 times the strength of the fan structure design;
To ensure product tolerances and dynamic balance, as accurate and reliable as the wheel of a car.
Motor reducer one by one
传统工业大风扇是由交流异步电动机带动减速机驱动，从而实现工业大风扇的转动。 ◆ The traditional industrial large fan is driven by the reducer driven by the AC asynchronous motor, so as to realize the rotation of the industrial large fan. However, driving through the reducer will bring a maintenance and maintenance problem of the reducer. The oil of the reducer needs to be changed regularly. The gears and bearings in the reducer need to be regularly checked and maintained. Once problems are found, parts and components need to be checked. Replacement is time-consuming, labor-intensive, and extremely expensive.
永磁同步电机直驱的工业大风扇由于由电机直接驱动，省去了减速机环节，没有齿轮和高速运转的轴承，因此就免去了更换机油、减少了齿轮及轴承的更换维护保养等工作，真正做了免维护，大大提高了工业大风扇的使用寿命，为用户带来了更可靠的体验。 ◆ Industrial large fan with direct drive of permanent magnet synchronous motor is directly driven by the motor, which eliminates the reducer link. There are no gears and high-speed bearings. Therefore, it is unnecessary to change the oil, reduce the maintenance of gears and bearings, etc. The work is truly maintenance-free, which greatly improves the service life of large industrial fans and brings a more reliable experience for users.
永磁同步电机直驱的工业大风扇由于采用稀土金属作为外转子，只要有效地控制电机的温升(传统款的使用环境温度均可)，寿命可以是无限长，可以为工业大风扇用户节省大量二次采购费用。 ◆ The permanent magnet synchronous motor direct-drive industrial large fan uses rare earth metal as the outer rotor, as long as the temperature rise of the motor can be effectively controlled (the traditional model can be used in the ambient temperature), the life can be infinitely long, and it can be a large industrial fan user Save a lot of secondary procurement costs.
传统工业大风扇都是减速电机在风扇的上方，重心偏高，特别容易造成整个风扇的晃动和摇摆，稳定性差。 ◆ Traditional industrial large fans are geared motors above the fans, with a high center of gravity, which is particularly easy to cause the entire fan to shake and sway, and the stability is poor. Our new permanent magnet synchronous direct-drive industrial large fan puts the drive motor under the fan blade, which is equivalent to adding a weight to the lower part of the large fan, which can effectively increase the stability of the large industrial fan. Large fans The operation is more stable and reliable, and the safety is greatly improved.
电机除了侧部用全包围结构外，上部和下部全部采用镂空结构。 ◆ Except for the motor that is fully enclosed on the side, the upper and lower parts are all hollowed out. The forged aluminum alloy chassis of the fan on the upper part is effectively combined with the upper cover of the motor, and the lower part uses a streamlined shroud designed for fluid mechanics. This effectively surrounds all internal structures such as the motor coil windings. The heat generated during the operation can be taken to the outside to be released to the maximum extent, and it can effectively protect the sundries from entering the motor and cause a safety fault.
