離心風機有哪些種類？之間有什麼區別？

離心式風機，在這一種風機上，有哪些是必須要知道和掌握的?以及離心式風機與貫流風機，具體區別在哪兒?這兩個問題，將它們提出來瞭，是為瞭讓大傢能夠知道文章內容，從而，來印花地坪有針對性進行學習，提高學習效率。
The centrifugal fan, in this kind of fan, which must know and master? And the centrifugal fan and the tubular fan, where are the specific differences? These two questions, they are put forward to let everyone know the content of the article, so as to study and improve the learning efficiency.
1.離心式風機中，有哪些是必須要知道和掌握的
離心式風機這一種風機中，必須要知道和掌握的知識內容，是有：
(1)在該風機中，有些規格型號是可以配置清理門離心式風機的，這樣，在風機維護過程中，不用進行拆卸工作瞭，這樣，可以節省維修時間。
(2)由於，離心式風機的通風效果是比較好的，所以其尤其適合用在管道抽風及送風上。
(3)其在管道輸送上，是可以來很好使用的嗎，而且，對於沒有腐蝕性及易燃易爆物品的場所，都可以使用離心式風機。
(4)在離心式風機中，其葉輪一般是采用後傾式，這樣，可以使得風機運行噪音小，且不容易積灰，從而，可以來方便進行維護工作。
1., what must be known and grasped in the centrifugal fan?
The knowledge contents that must be known and grasped in centrifugal fans are:
(1) in the fan, some specifications and models can be configured to clean the centrifugal fan of the door. In this way, in the maintenance process of the fan, the disassembly work is not needed, thus the maintenance time can be saved.
(2) because the centrifugal fan has better ventilation effect, it is especially suitable for ventilation and air supply.
(3) is it wel环氧地坪l used in pipeline transportation, and centrifugal fans can be used in places where there are no corrosiveness and inflammable and explosive items.
(4) in the centrifugal fan, the impeller is generally used back tilting, so that the noise of the fan running is small, and it is not easy to accumulate ash, so it can be convenient for maintenance work.
2.離心式風機與貫流風機的區別The difference between 2. centrifugal fan and tubular fan
區別一：原理
離心式風機：是利用動能轉換成勢能這一原理，通過葉輪將氣體加速和減速，並改變其的流動方向，從而，來達到使用目的的。
貫流風機：該風機中的氣流，是貫穿葉輪來流動的，而且，會受到兩次力的作用。所以，在輸送距離上，可以很長。
Difference one: Principle
Centrifugal fan: it is the principle that the kinetic energy is converted into potential energy, which accelerates and decelerates the gas through the impeller and changes its flow direction, so as to achieve the purpose of use.
Cross flow fan: the air flow in the fan runs through the impeller, and it will be affected by the two force. So, in the distance, it can be very long.
區別二：構造
離心式風機是由機殼、葉輪、主軸、電機以及傳動機構等構成的，而貫流風機，則有些不同。而且，在葉輪上，貫流風機是以長圓筒形的多葉式居多，而在離心式風機上，則不是這樣的。
Difference two: structure
Centrifugal fan is made up of casing, impeller, spindle, motor and transmission mechanism, while the cross flow fan is different. Moreover, on the impeller, the cross flow fan is mostly in a long cylindrical multi leaf type, but not on the centrifugal fan.
