雖然近年來，各大水泥企業(yè)都在積極更換原來的羅茨風(fēng)機(jī)，但是前磁懸浮鼓風(fēng)機(jī)的應(yīng)用情況并不是很了解。磁懸浮鼓風(fēng)機(jī)是將磁懸浮軸承技術(shù)和高速電機(jī)技術(shù)融入到傳統(tǒng)風(fēng)機(jī)之中所形成的一種高效、節(jié)能、環(huán)保的新型產(chǎn)品。磁懸浮軸承系統(tǒng)是磁懸浮鼓風(fēng)機(jī)的核心系統(tǒng)，轉(zhuǎn)子位于兩個徑向磁軸承和兩個軸向磁軸承之間，轉(zhuǎn)子的位置由位置傳感器實(shí)時監(jiān)測，并反饋到磁軸承控制器。當(dāng)轉(zhuǎn)子位置發(fā)生偏移時，控制器會根據(jù)轉(zhuǎn)子的偏移量調(diào)節(jié)磁軸承各自由度的磁場力，使轉(zhuǎn)子保持在正確的位置。

Although major cement companies have been actively replacing their original Roots blowers in recent years, the application of the front magnetic levitation blower is not well understood. Magnetic levitation blower is a new type of high-efficiency, energy-saving, and environmentally friendly product formed by integrating magnetic levitation bearing technology and high-speed motor technology into traditional fans. The magnetic levitation bearing system is the core system of the magnetic levitation blower, with the rotor located between two radial magnetic bearings and two axial magnetic bearings. The position of the rotor is monitored in real-time by a position sensor and fed back to the magnetic bearing controller. When the rotor position deviates, the controller will adjust the magnetic field force of each degree of freedom of the magnetic bearing according to the displacement of the rotor, so as to keep the rotor in the correct position.

那么磁懸浮鼓風(fēng)機(jī)又有什么優(yōu)勢呢

So what are the advantages of magnetic levitation blower

性能優(yōu)勢

Performance advantages

與羅茨鼓風(fēng)機(jī)相比，磁懸浮鼓風(fēng)機(jī)的效率提高了30%~40%。以 100kw 磁懸浮鼓風(fēng)機(jī)為例，與羅茨鼓風(fēng)機(jī)相比，每臺磁懸浮鼓風(fēng)機(jī)每年可以節(jié)約用電30 多萬度。

Compared with Roots blower, the efficiency of magnetic levitation blower has been improved by 30% to 40%. Taking the 100kw magnetic levitation blower as an example, compared with the Roots blower, each magnetic levitation blower can save more than 300000 kWh of electricity per year.

環(huán)保優(yōu)勢

Environmental advantages

磁懸浮鼓風(fēng)機(jī)無需潤滑，輸送的空氣清潔無污染。磁懸浮軸承完全無摩擦，鼓風(fēng)機(jī)運(yùn)行噪音低，不會影響周邊辦公及居住環(huán)境。以100kw 磁懸浮鼓風(fēng)機(jī)計(jì)算，每臺鼓風(fēng)機(jī)每年可減少約 275噸的二氧化碳排放量。

Magnetic levitation blower does not require lubrication and delivers clean and pollution-free air. Magnetic levitation bearings are completely frictionless, and the blower operates with low noise, which will not affect the surrounding office and living environment. Based on a 100kw magnetic levitation blower, each blower can reduce approximately 275 tons of carbon dioxide emissions per year.

技術(shù)優(yōu)勢采用主動磁懸浮軸承系統(tǒng)，無磨損，不需要潤滑與維護(hù)。采用高性能變頻器對轉(zhuǎn)速進(jìn)行控制，多種控制模式可以選擇。先進(jìn)的控制系統(tǒng)，運(yùn)行轉(zhuǎn)臺可以實(shí)時監(jiān)控，并且可以遠(yuǎn)程控制，無需人員現(xiàn)場值守。全封閉風(fēng)冷系統(tǒng)對電機(jī)進(jìn)行散熱，確保風(fēng)機(jī)處于穩(wěn)定高效的運(yùn)行狀態(tài)。模塊化設(shè)計(jì)，維修方便快捷。

The technological advantage is the use of an active magnetic levitation bearing system, which is wear-resistant and does not require lubrication or maintenance. High performance frequency converters are used to control the speed, with multiple control modes to choose from. Advanced control system, the turntable can be monitored in real-time and remotely controlled without the need for on-site personnel. The fully enclosed air cooling system dissipates heat from the motor to ensure that the fan is in a stable and efficient operating state. Modular design, easy and fast maintenance.

成本優(yōu)勢

cost advantage

磁懸浮軸承完全無摩擦，減少產(chǎn)品的損壞幾率，鼓風(fēng)機(jī)的使用壽命可以達(dá)到 20 年以上。維護(hù)簡單，只需定期更換過濾器、過濾棉，基本免維護(hù)。不需要潤滑系統(tǒng)，節(jié)約了潤滑油、清潔等費(fèi)用。電機(jī)采用直聯(lián)驅(qū)動，體積小，重量輕，節(jié)約空間。

Magnetic levitation bearings are completely frictionless, reducing the probability of product damage, and the service life of the blower can reach more than 20 years. Easy maintenance, only need to regularly replace filters and filter cotton, basically maintenance free. No lubrication system is required, saving costs such as lubricating oil and cleaning. The motor adopts direct drive, with small size, light weight, and space saving.

目前國內(nèi)部分磁懸浮采用普通空氣冷卻，而這種冷卻方式很容易造成機(jī)房溫度高，風(fēng)機(jī)工作能耗高，效率低。針對這種情況，華東磁懸浮鼓風(fēng)機(jī)采用了內(nèi)循環(huán)水冷+空冷工藝，溫升低，同時也不會受到外部環(huán)境溫度的影響，更具有競優(yōu)勢。

At present, some maglev systems in China use ordinary air cooling, which can easily cause high temperatures in the computer room, high energy consumption during fan operation, and low efficiency. In response to this situation, the East China Maglev blower adopts an internal circulation water cooling+air cooling process, which has a low temperature rise and is not affected by external environmental temperature, making it more competitive.
