持續離心風機：壓頭大、客流量小。軸（zhóu）流風機的氣旋大方向鉛垂（chuí）線與風向標的（de）革命大方向，持續離心風機（jī）的氣旋大方向切（qiē）於風向標革命大方向。錄取怎麽著方式的風機最重點的是全麵考（kǎo）慮客流量及係統障礙物破（pò）財.軸流風機的主要特點是半流體本著扇葉（yè）的軸向橫貫。進行諸如電電風扇和家庭生活裏的訴諸公論扇（shàn）。而持續離心式是將半流體趕浪（làng）頭扇（shàn）的軸向進（jìn）行吸氣後使用持續（xù）離心力將半流體從圓周大方向甩出來，進行諸如鼓風機，抽煤（méi）煙機.軸流風機:客流量大、壓頭小。
Centrifugal fan: large head and small flow. The flow direction of axial fan is perpendicular to the rotating direction of blade, and the flow direction of centrifugal fan is tangent to the rotating direction of blade. The most important thing to choose is to consider the flow rate and system resistance loss. The axial flow fan is characterized by the axial flow of fluid along the fan blade. For example, fans and household exhaust fans. The centrifugal type is the axial suction of fluid from the fan after the use of centrifugal force will be the fluid from the circumferential direction to throw out, such as blowers, smoke pumping machines.
持續離心風機比較軸（zhóu）流風機，更加最大的毛病就是說容積大，正其主要原因在於（yú）雙方的組織（zhī）有所（suǒ）區別，在雷同風（fēng）量，雷同風壓的狀（zhuàng）況下，持續（xù）離心風機的經費（fèi）量要比軸流風機大許許多多（duō），不（bú）過噪聲（shēng）會比較而言小，因此軸流風機更加多用在消防（fáng）工作建（jiàn）築通風層（céng）麵，平常（cháng）采用的風機多錄取持續離心風機。 在飯店類高級的建築物裏，許許（xǔ）多多（duō）具（jù）體要求進行先鞭采用持續離心風機
The biggest disadvantage of centrifugal fans is that they are bulky compared with axial-flow fans. Because of their different structures, centrifugal fans consume much more electricity than axial-flow fans under the same air volume and pressure, but the noise will be relatively small. Therefore, axial-flow fans are often used in fire fighting and ventilation. Centrifugal fans are selected. Ting Da import bearing Miss Wang in the high-grade hotel buildings, many require the priority use of centrifugal fan.
軸流，就是說與風葉的軸同大方向的氣旋。持續離心（xīn），靠持續離心力把氣旋甩呈現出來的。
Axial flow is the same direction as the axis of the blade. Centrifugation, the air is thrown out by centrifugal force.
風的動向和軸是平行線的就叫軸流風機，(進行諸（zhū）如消防工作（zuò）的進行煙油風機（jī）)反而就是說持續離心風（fēng）機，(進行（háng）諸如風機盤（pán）管的風（fēng）機).
The flow direction of the wind is parallel to the axis is called axial fan (such as fire exhaust fan) and vice versa is centrifugal fan (such as fan coil fan).
軸流（liú）風機和櫃式持續離心風機的重要差異在風機的機械整體結構上：
The fundamental difference between axial fan and cabinet centrifugal fan is in the mechanical structure of the fan.
軸流風機的風向標有（yǒu）關直徑受製於殼子的有關直徑，而持續離心風機就並未有關這方麵的受製，能夠使用風向標前傾或後傾風向標，對（duì）風量風（fēng）壓的具體要（yào）求能夠適應更廣。並且櫃內能（néng）做消聲采用相應辦法解決，在噪音參照上有很顯著的主要（yào）優勢。
Axial fan blade diameter is limited to the diameter of the shell, and centrifugal fan has no limitations in this respect, can be used blade tilt forward or backward blade, wind pressure requirements to adapt to a wider range. Moreover, the cabinet can make noise reduction, and has obvious advantages in noise indicators. Ding Da import bearing Miss Wang
因（yīn）為通常使用發（fā）電機的轉數較低，發電機權力大，經費相（xiàng）許多些。在滿足相關條件時平常合同建築通風係統，盡可能使用（yòng）櫃式持續離心風機，消（xiāo）防工作進行煙油偶然（rán）用的係統，使（shǐ）用恒溫軸流風機更經（jīng）濟領域較為合理!
Generally speaking, the number of motors is low, the power of the motor is large, and the power consumption is much more. If the usual ventilation system, try to use cabinet centrifugal fan, fire smoke exhaust system is not commonly used, the use of high-temperature axial fan is more economical and reasonable!
持續離心風機比（bǐ）軸流風機在暴風量和暴風（fēng）壓的結合（hé）挑選上更有主要優勢（shì）(重點（diǎn）指風機工作效率和噪音參照上)!
Centrifugal fans have more advantages than axial flow fans in the selection of combination of high wind volume and high wind pressure (mainly refers to fan efficiency and noise index)!
持續離心風機和軸流風機差異參加：
The difference between centrifugal fan and axial fan is that:
1、持續離心風機成為了風缸管電介質（zhì）的動（dòng）向，而軸流風機不成為風缸（gāng）管電介質的動向;
1. The centrifugal fan changes the flow direction of the medium in the duct, while the axial fan does not change the flow direction of the medium in the duct.
2、前端風量四級風壓都更加很（hěn）大（dà），後人風量四級風壓（yā）都很低;
2, the former has great air volume and wind pressure, and the latter has low air volume and wind pressure.
3、前端進行安裝較較為複雜，後人進行（háng）安裝較更為簡便;
3, the former installation is more complex, and the latter is simpler to install.
4、前端發電（diàn）機與風機通（tōng）常是借助軸包（bāo）括的，後人發電機通常（cháng）在風機內;
4, the former motor and fan are usually connected by shaft, and the latter motor is usually in the fan.
5、前端常進行安裝在空調機醫衛組進、說道處（chù），火爐鼓（gǔ）、引風機，等等，後人常（cháng）進行安裝在（zài）風管正當中、或風管說道前端和後端（duān）。
5. The former is often installed at the inlet and outlet of air-conditioning units, boiler drum, induced draft fan, etc. The latter is often installed in the air duct, or the front end of the air duct outlet.
