之所以叫離心風機是因為它依靠葉輪旋轉(zhuǎn)的離心力使氣體沿軸向吸入，但徑向吹出。其結(jié)構(gòu)的特點使它相比軸流風機而言能承受更大的風壓。
As its name implies, centrifugal fans inhale the air along the axial direction, but blown out radially based on the centrifugal force of impeller rotation.
ebm papst離心風機根據(jù)葉輪結(jié)構(gòu)的不同分為前向離心風機和后向離心風機。不同的葉輪造就了兩種風機不同的特點和應(yīng)用。
ebm papst centrifugal fans are divided into forward and backward centrifugal fans. Different impeller makes the difference in their features and applications.
前向離心風機葉片尺寸小、數(shù)量多、密度大，因此整體結(jié)構(gòu)更緊湊且運行安靜，適用于狹小空間和高風壓環(huán)境，但它輸出的風量較小，一般需搭配蝸殼使用。
Blades of forward centrifugal fans are small in size, large in number, and high in density, so the overall structure is more compact and the operation is quiet. It is suitable for small spaces and high wind pressure environments, but its output air volume is small, and it generally needs to be used with volute casing.
后向離心風機采用自由輪設(shè)計，無需蝸殼，相比前向離心風機而言，它能輸出更大的風量，但能承受的風壓較小。
The backward centrifugal fan adopts a free wheel design and does not need a volute. Compared with the forward centrifugal fan, it can output a larger air volume, but it can withstand a lower wind pressure.
對于帶有外轉(zhuǎn)子電機的離心風機，電機集成于葉輪中，這樣不僅可以確保電機的出色冷卻效果，還可以實現(xiàn)非常緊湊的設(shè)計。
For centrifugal fans with external rotor motors, the motor is integrated in the impeller, which not only ensures excellent cooling effect of the motor, but also realizes a very compact design.
整個產(chǎn)品系列提供AC風機和采用EC技術(shù)的EC風機，EC風機除了節(jié)能之外，集成的控制電路還可以實現(xiàn)控制、監(jiān)測和維護功能，尤其適合凈化，工業(yè)空調(diào)，新風系統(tǒng)、電子冷卻等相關(guān)應(yīng)用。
The entire product series provides AC fans and EC fans with EC technology. In addition to energy saving, EC fans can also realize control, monitoring and maintenance functions with integrated control circuits, especially suitable for purification, industrial air conditioning, fresh air systems, electronic cooling and other related applications.
ebm離心風機是離心設(shè)計中無與倫比的高壓專家，具有90°空氣偏轉(zhuǎn)和精心優(yōu)化的葉輪。
ebm centrifugal fans are unrivaled high-pressure specialists in centrifugal design with 90° air deflection and carefully optimized impellers.
多年來，ebm風機一直是電子冷卻行業(yè)的佼佼者。風機結(jié)構(gòu)緊湊、運行安靜且高效，伙伴們有用到離心風機有相關(guān)技術(shù)問題可以私信或是給我留言哦。
