磁懸浮鼓風(fēng)機(jī)主要由高效離心葉輪、磁懸浮軸承、永磁同步電機(jī)和專(zhuān)用變頻器四部分精密集成。其設(shè)計(jì)核心在于磁懸浮軸承和永磁電機(jī)技術(shù)，確保了風(fēng)機(jī)的高效、靜音及無(wú)磨損運(yùn)行。

　　The magnetic levitation blower mainly consists of four precision integrated parts: high-efficiency centrifugal impeller, magnetic levitation bearing, permanent magnet synchronous motor, and dedicated frequency converter. The core of its design lies in magnetic levitation bearings and permanent magnet motor technology, ensuring the efficient, silent, and wear free operation of the fan.

　　High speed centrifugal impeller

　　葉輪采用先進(jìn)的三元流動(dòng)理論進(jìn)行設(shè)計(jì)，并經(jīng)過(guò)參數(shù)優(yōu)化，以最大化葉輪效率，拓寬其工作區(qū)域。材質(zhì)上，它選用高強(qiáng)度鍛鋁或鈦合金，抗變形能力強(qiáng)，且在數(shù)控加工中心精密加工后，防腐性能更佳。經(jīng)國(guó)家流體實(shí)驗(yàn)室專(zhuān)家測(cè)試，葉輪工作點(diǎn)最高效率可達(dá)85%。

　　The impeller is designed using advanced ternary flow theory and parameter optimization to maximize impeller efficiency and expand its working area. In terms of material, it is made of high-strength forged aluminum or titanium alloy, which has strong deformation resistance and better anti-corrosion performance after precision machining on CNC machining centers. According to experts from the National Fluid Laboratory, the maximum efficiency of the impeller working point can reach 85%.

　　高速永磁同步電機(jī)

　　High speed permanent magnet synchronous motor

　　電機(jī)主軸上安裝的永磁鐵保證了主軸的磁性，而其定子硅鋼片上的線圈則產(chǎn)生震蕩磁力，與電機(jī)轉(zhuǎn)速保持一致，實(shí)現(xiàn)同步旋轉(zhuǎn)。永磁電動(dòng)機(jī)與磁懸浮軸承的結(jié)合，使得它具有無(wú)機(jī)械摩擦、低噪音、低振動(dòng)以及長(zhǎng)壽命的特點(diǎn)，最高轉(zhuǎn)速可達(dá)50000r/min。

　　The permanent magnet installed on the motor spindle ensures the magnetic properties of the spindle, while the coil on the stator silicon steel sheet generates oscillating magnetic force, which is consistent with the motor speed and achieves synchronous rotation. The combination of permanent magnet motor and magnetic levitation bearing makes it have the characteristics of no mechanical friction, low noise, low vibration, and long service life, with a maximum speed of up to 50000r/min.

　　Magnetic levitation bearings

　　通過(guò)可控電磁吸力，磁懸浮軸承能穩(wěn)定地使轉(zhuǎn)軸懸浮，消除旋轉(zhuǎn)過(guò)程中的機(jī)械阻力，從而提高效率，實(shí)現(xiàn)無(wú)磨損、免維護(hù)、無(wú)需潤(rùn)滑油，且輸出的空氣不含油。

　　Through controllable electromagnetic suction, magnetic levitation bearings can stably suspend the shaft, eliminate mechanical resistance during rotation, thereby improving efficiency, achieving wear free, maintenance free, lubrication free, and oil-free output air.

　　電機(jī)智能控制系統(tǒng)

　　Intelligent Motor Control System

　　磁懸浮鼓風(fēng)機(jī)通常采用無(wú)矢量變頻控制，通過(guò)調(diào)節(jié)頻率來(lái)控制永磁電機(jī)的旋轉(zhuǎn)，進(jìn)而調(diào)節(jié)鼓風(fēng)機(jī)的流量，滿(mǎn)足各種工況需求。其智能控制系統(tǒng)還能預(yù)測(cè)喘振、實(shí)現(xiàn)就地控制，并通過(guò)GPRS系統(tǒng)實(shí)現(xiàn)遠(yuǎn)程監(jiān)控和數(shù)據(jù)傳輸。

　　Magnetic levitation blowers usually use vector free variable frequency control to control the rotation of permanent magnet motors by adjusting the frequency, thereby adjusting the flow rate of the blower to meet various working conditions. Its intelligent control system can also predict surge, achieve on-site control, and achieve remote monitoring and data transmission through GPRS system.

　　工藝參數(shù)

　　Process parameters

　　功率：磁懸浮鼓風(fēng)機(jī)的功率范圍從50kW到1WM，提供多種型號(hào)選擇，滿(mǎn)足不同用戶(hù)的需求。同時(shí)，它支持多機(jī)聯(lián)動(dòng)控制，多臺(tái)設(shè)備可協(xié)同工作，進(jìn)一步提升效率。

　　Power: The power range of the magnetic levitation blower is from 50kW to 1WM, providing multiple models to meet the needs of different users. At the same time, it supports multi machine linkage control, allowing multiple devices to work together and further improve efficiency.

　　風(fēng)量：風(fēng)量范圍從30m3/min到660m3/min，且風(fēng)量變頻可調(diào)。單臺(tái)設(shè)備風(fēng)量調(diào)節(jié)范圍高達(dá)50%，可根據(jù)水質(zhì)情況靈活調(diào)節(jié)風(fēng)量。

　　Air volume: The air volume range is from 30m3/min to 660m3/min, and the air volume can be adjusted by frequency conversion. The air volume adjustment range of a single device can reach up to 50%, and the air volume can be flexibly adjusted according to the water quality.

　　升壓：升壓范圍覆蓋40kPa至150kPa，壓力變頻可調(diào)。這一設(shè)計(jì)能有效應(yīng)對(duì)水位變化帶來(lái)的壓力波動(dòng)，實(shí)現(xiàn)快速響應(yīng)，滿(mǎn)足存在壓力變化的工藝需求。

　　Boosting: The boosting range covers 40kPa to 150kPa, and the pressure can be adjusted by frequency conversion. This design can effectively cope with pressure fluctuations caused by water level changes, achieve rapid response, and meet the process requirements of pressure changes.

　　高速永磁同步電機(jī)與葉輪直接耦合驅(qū)動(dòng)，有效消除了機(jī)械傳動(dòng)損失，使得轉(zhuǎn)速高達(dá)50000RPM，效率超過(guò)85%。在噪音控制方面，該鼓風(fēng)機(jī)表現(xiàn)出色，噪音水平不超過(guò)85分貝，遠(yuǎn)低于人類(lèi)可承受的安全噪音標(biāo)準(zhǔn)。由于缺乏機(jī)械摩擦，噪音主要來(lái)源于空氣的高速流動(dòng)，屬于高頻噪音，傳播距離相對(duì)較短，易于通過(guò)管道包覆等方式進(jìn)行控制。

　　The high-speed permanent magnet synchronous motor is directly coupled with the impeller for driving, effectively eliminating mechanical transmission losses, resulting in a speed of up to 50000 RPM and an efficiency of over 85%. In terms of noise control, the blower performs excellently, with a noise level not exceeding 85 decibels, far below the safe noise standards that humans can tolerate. Due to the lack of mechanical friction, the noise mainly comes from the high-speed flow of air, which belongs to high-frequency noise. The propagation distance is relatively short, and it is easy to control through methods such as pipeline wrapping.
