離心風機

Centrifugal fan

依靠輸入的機械能，提高氣體壓力并排送氣體的機械，它是一種從動的流體機械。

Relying on the input mechanical energy, it is a driven fluid machinery that increases the gas pressure and discharges the gas.

離心風機廣泛用于：

Centrifugal fans are widely used in:

①工廠、礦井、隧道、冷卻塔、車輛、船舶和建筑物的通風、排塵和冷卻；

① Ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings;

②鍋爐和工業爐窯的通風和引風；

② Ventilation and induced draft of boilers and industrial furnaces;

③空氣調節設備和家用電器設備中的冷卻和通風；

③ Cooling and ventilation in air conditioning equipment and household electrical appliances;

④谷物的烘干和選送；

④ Drying and selection of grain;

⑤風洞風源和氣墊船的充氣和推進等。

⑤ Wind tunnel wind source and inflation and propulsion of hovercraft.

2、軸流風機

2. Axial flow fan

就是與風葉的軸同方向的氣流，如電風扇，空調外機風扇就是軸流方式運行風機。之所以稱為“軸流式”，是因為氣體平行于風機軸流動。

It is the air flow in the same direction as the axis of the fan blade, such as the electric fan. The fan of the external unit of the air conditioner is the fan operating in the axial flow mode. It is called "axial flow type" because the gas flows parallel to the fan axis.

軸流式風機通常用在流量要求較高而壓力要求較低的場合。

Axial flow fans are usually used in occasions with high flow requirements and low pressure requirements.

軸流式風機固定位置并使空氣移動。

The axial flow fan is fixed in position and moves the air.

特點：

characteristic:

小型軸流風機：功耗低、散熱快、噪音低、節能環保等。由于體積小用途比較廣泛。

Small axial fan: low power consumption, fast heat dissipation, low noise, energy conservation and environmental protection. Because of its small size, it is widely used.

大型軸流風機：具有結構簡單、穩固可靠、噪聲小、風量大、功能選擇范圍廣等特點。

Large axial flow fan: it has the characteristics of simple structure, stability and reliability, low noise, large air volume and wide range of function selection.

3、斜流風機/混流風機

3. Diagonal flow fan / mixed flow fan

介于軸流風機和離心風機之間的風機，斜流風機的葉輪讓空氣既做離心運動又做軸向運動，殼內空氣的運動混合了軸流與離心兩種運動形式。

For the fan between axial flow fan and centrifugal fan, the impeller of diagonal flow fan makes the air do both centrifugal and axial movement. The movement of air in the shell is a mixture of axial flow and centrifugal movement.

結合了軸流式和離心式風機的特征，盡管它看起來更像傳統的軸流式風機。將彎曲板形葉片焊接在圓錐形鋼輪轂上。通過改變葉輪上游入口外殼中的葉片角度來改變流量。機殼可具有敞開的入口，但更常見的情況是，它具有直角彎曲形狀，使電機可以放在管道外部。排泄殼緩慢膨脹，以放慢空氣或氣體流的速度，并將動能轉換為有用的靜態壓力。

It combines the characteristics of axial and centrifugal fans, although it looks more like a traditional axial fan. The curved plate blade is welded to the conical steel hub. The flow is changed by changing the blade angle in the inlet housing upstream of the impeller. The casing can have an open inlet, but more often it has a right angle bending shape so that the motor can be placed outside the pipe. The discharge shell expands slowly to slow down the flow of air or gas and convert kinetic energy into useful static pressure.

主要用于礦井通風和隧道通風。

It is mainly used for mine ventilation and tunnel ventilation.

兩者的區別：

The difference between the two:

1、離心風機改變了風管內介質的流向，而軸流風機不改變風管內介質的流向；

1. The centrifugal fan changes the flow direction of the medium in the air duct, while the axial fan does not change the flow direction of the medium in the air duct;

2、前者安裝較復雜。

2. The installation of the former is more complex.

3、前者電機與風機一般是通過皮帶帶動轉動輪連接的，后者電機一般在風機內；

3. The motor of the former is generally connected with the fan through the belt to drive the rotating wheel, while the motor of the latter is generally in the fan;

4、前者常安裝在空調機組進、出口處，鍋爐鼓、引風機，等等。后者常安裝在風管當中、或風管出口前端。

4. The former is often installed at the inlet and outlet of the air conditioning unit, boiler drum, induced draft fan, etc. The latter is often installed in the middle of the air duct or at the front end of the air duct outlet.

5、前者是空氣收入后加壓，后者是正壓驅動。

5. The former is pressurized after air income, and the latter is driven by positive pressure.

斜流(混流)風機:

Diagonal flow (mixed flow) fan:

1、風壓系數比軸流風機高，流量系數比離心風機大。

1. The wind pressure coefficient is higher than that of axial flow fan, and the flow coefficient is greater than that of centrifugal fan.

2、填補了軸流風機和離心風機之間的空白。

2. It fills the gap between axial flow fan and centrifugal fan.

3、安裝簡單方便。

3. The installation is simple and convenient.

離心風機 跟 軸流風機 在啟動時的差別：

Difference between centrifugal fan and axial flow fan at startup:

離心風機的運轉功率隨著風量的增加而增加，所以離心風機在啟動時風門要全關，然后再逐漸打開，避免風機電流過大而燒毀電機。

The operating power of the centrifugal fan increases with the increase of air volume, so the air door of the centrifugal fan should be fully closed when starting, and then gradually opened to avoid burning the motor due to excessive fan current.

軸流風機的運轉功率隨著風量的增加而減少，所以軸流風機在啟動時，風門要全開，然后再逐步關閉到所需的風量值。

The operating power of the axial flow fan decreases with the increase of air volume, so when the axial flow fan is started, the damper shall be fully opened, and then gradually closed to the required air volume value.
