空气悬浮离心式鼓风机,是以变频器驱动电机,叶轮与轴直连,综合应用空气轴承(Air Bearing), 叶轮(Impeller), 高速电机(High Speed Motor), 变频器(Inverter), 控制器(Controller) 等多项技术,提供压缩空气的设备。

Air suspension centrifugal blower is a frequency converter drive motor, impeller and shaft connection, comprehensive application of air bearing (Air Bearing), the impeller (Impeller), high speed motor (High Speed Motor), frequency converter (Inverter), the controller (Controller) technology, to provide compressed air equipment.

故而空浮风机的发展也是伴随着这几大核心技术的发展,归纳如下:

Therefore, the development of air floats is accompanied by the development of these key technologies, which are summarized as follows:

1:智能精确控制技术的发展。即:控制器+变频系统+高速电机的发展

1: the development of intelligent and precise control technology. That is, the development of controller + frequency conversion system and high speed motor

2:稳定性、安全性的发展。即:空气悬浮轴承+永磁转轴+叶轮+冷却系统的发展

2: the development of stability and security. That is, the development of air suspension bearing, permanent magnet rotating shaft + impeller + cooling system

悬浮技术无需轴承与转子接触的特点决定转子转速可以达到23000到30000转,在这样的高速要求下,设计之初必然会对风机提出以下罗列的基本技术保障:

The suspension technology does not require the contact between the bearing and the rotor, which determines that the rotor speed can reach 23000 to 30000 rpm. At such a high speed requirement, the basic technical guarantee for the fan will be listed at the beginning of the design.

1. 近乎“0”振动的技术要求,这就控制技术以及变频器的选用提出苛刻的要求,以及控制器对变频器控制技术的要求,高速电机运行时,变频器驱动电机时,必须提供稳定信号,才能使得电机稳定运行,同时电机类型的选用,离心风机都有高、低压喘振和固有频率共振问题,需要从控制技术上规避这些危险区域。

1. close to "0" vibration technology, the control technology and frequency selection of demanding, and requires the controller to control frequency converter technology, high-speed motor, inverter motor drive, must provide a stable signal, in order to make the motor stable operation, and the type of motor, centrifugal fan are there are high and low voltage surge and resonance problem, need to avoid these dangers from control technology.

2.转子的要求,空气悬浮离心式鼓风机特点叶轮与转轴直接连接。空气由于采用空气悬浮轴承技术,在轴承负载力相当的情况下,对转子的重量是有苛刻要求的:转子越轻,轴承的寿命会得到显著的保障。

The requirement of the 2. rotor, the characteristic impeller of the air suspension centrifugal blower is directly connected with the rotating shaft. Due to the use of air bearing technology, under the condition of the same bearing load, the air has strict requirements for the weight of the rotor. The lighter the rotor is, the better the life of the bearing will be.

3. 对机箱内运行环境温度的要求,市面上空气悬浮离心式鼓风机都是一体式,即空气轴承, 叶轮, 高速电机, 变频器, 控制部分,等部件都整合到一个箱体内,高速离心风机都有高散热的特点,如何有效解决散热的问题才是空气悬浮离心式鼓风机比较为重要的技术难题。风机如何控制散热的问题上,是对不能疏忽的。

3. of the chassis operation requirements of the ambient temperature on the market of air suspending centrifugal blower is integrated, namely air bearing, impeller, high speed motor, inverter, control, and other components are integrated into a box body, a high speed centrifugal fan has the characteristics of high heat dissipation, how to effectively solve the heat problem that is the most important technical problems for air suspension centrifugal blower. How the fan control the problem of heat dissipation is absolutely inadvertent.
