Centrifugal fanA centrifugal fan (also squirrel-cage fan, as it looks like a hamster wheel) is a mechanical device for moving air or gases. It has a fan wheel composed of a number of fan blades, or ribs, mounted around a hub. As shown in Figure 1, the hub turns on a driveshaft that passes through the fan housing. The gas enters from the side of the fan wheel, turns 90 degrees and accelerates due to centrifugal force as it flows over the fan blades and exits the fan housing.Centrifugal fans can generate pressure rises in the gas stream. Accordingly, they are well-suited for industrial processes and air pollution control systems. They are also common in central heating/cooling systems.1. Fan componentsThe major components of a typical centrifugal fan include the fan wheel, fan housing, drive mechanism, and inlet and/or outlet dampers.2. Types of drive mechanismsThe fan drive determines the speed of the fan wheel (impeller) and the extent to which this speed can be varied. There are three basic types of fan drivers.2.1 Direct driveThe fan wheel can be linked directly to the shaft of an electric motor. This means that the fan wheel speed is identical to the motor’s rotational speed. With this type of fan drive mechanism, the fan speed cannot be varied unless the motor speed is adjustable.2.2.1 Belt driveBelt drive fans use multiple belts that rotate in a set of sheaves mounted on the motor shaft and the fan wheel shaft.This type of drive mechanism is depicted in figure 2. The belts transmit the mechanical energy from the motor to the fan.The fan wheel speed depends upon the diameter of the motor sheave to the diameter of the fan wheel sheave and can be obtained from this equation:Where:= fan wheel speed, revolutions per minute= motor nameplate speed, revolutions per minute= diameter of the motor sheave= diameter of the fan wheel sheaveFan wheel speeds in belt-driven fans are fixed unless the belts slip. Belt slippage can reduce the fan wheel speed several hundred revolutions per minute (rpm).2.2 Variable driveVariable drive fans use hydraulic or magnetic couplings (between the fan wheel shaft and the motor shaft) that allow control of the fan wheel speed independent of the motor speed. The fan speed controls are often integrated into automated systems to maintain the desired fan speed.An alternate method of varying fan speed is by use of an electronic variable-speed drive which controls the speed of the motor driving the fan. This offers better overall energy efficiency at reduced speeds than mechanical couplings.2.3 Fan dampersFan dampers are used to control gas flow into and out of the centrifugal fan. They may be installed on the inlet side or on the outlet side of the fan, or both. Dampers on the outlet side impose a flow resistance that is used to control gas flow. Dampers on the inlet side are designed to control gas flow and to change how the gas enters the fan wheel.Inlet dampers reduce fan energy usage due to their ability to affec t the airflow pattern into the fan.3. Backward-curved bladesBackward-curved blades, as in figure 3(b), use blades that curve against the direction of the fan wheel’s rotation. The backward curvature mimics that of an airfoil cross section and provides good operating efficiency with relatively economical construction techniques. These types of fan wheels are used in fans designed to handle gas streams with how to moderate particulate loadings. They can be easily fitted with wear protection but certain blade curvatures can be prone to solids build-up.Backward curved fans can have a high range of specific speeds but are most often used for medium specific speed application—high pressure, medium flow applications.Backward-curved fans are much more energy efficiency than radial blade fans and so, for high horsepower applications may be a suitable alternative to the lower cost radial bladed fan.4. Straight radial bladesRadial fan blades, as in figure 3(c), extend straight out from the hub. A radial blade fan wheel is often on particular-laden gas streams because it is the least sensitive to solids build-up on the blades, but it is often characterized by greater noise output. High speeds, low volumes, and high pressure are common with radial fans, and are often used in vacuum cleaners, pneumatic conveying systems, and similar processes.5. Centrifugal fan ratingsRatings found in centrifugal fan performance tables and curves are based on standard air SCFM. Fan manufacturers define standard air as clean, dry air with a density of 0.075 pounds mass per cubic foot (1.2kg/m^3), with the barometric pressure at sea level of 29.92 inches of mercury (101.325kPa) and a temperature of 70F. Selecting a centrifugal fan to operate at conditions other than standard air requires adjustment to both static pressure and brake horsepower. The volume of air will not be affected in a given system because a fan will move the same amount of air regardless of the air density.If a centrifugal fan is to operate at a non-standard density, then corrections must be made to static pressure and brake horsepower. At higher than standard elevation (sea veal) and higher than standard temperature, air density is lower than standard density. Centrifugal fans that are specified for continuous operation at higher temperatures need to be selected taking into account air density corrections. Again, a centrifugal fan is a constant volume device that will move the same amount of air at tow different temperatures.If, for example, a centrifugal fan moves 1,000ft^3/min (28 m^3/min) at 70F it will also move 1,000ft^3/min (28 m^3/min) at 200F. Centrifugal fan air volume delivered by the centrifugal fan is not affected by density. However, since the 200f air weights much less than the 70f air, the centrifugal fan will create less static pressure and will require less brake horsepower. Selecting a centrifugal fan to operate atconditions other than standard air requires adjustment to both static pressure and power. When a centrifugal fan is specified for a given CFM and static pressure at conditions other than standard, an air density correction factor must be applied to select the proper size fan to meet the new condition. Since 200f air weighs only 80% of 70f air, the centrifugal fan will create less pressure. To get the actual pressure required at 200f , the designer would have to multiply the pressure at standard conditions by an air density correction factor of 1.25 (i.e.,1.0/0.8) to get the system to operate correctly. To get the actual power at 200f, the designer would have to divide the power at standard conditions by the air density correction factor.离心风机离心风机（也称鼠笼式风扇，因为它看起来像仓鼠笼）是一种机械装置移动空气或气体。

用途4-72型离心通风机主要用途是为一般工厂及大型建筑物的室内通风换气或输送空气及其它不自燃、不易爆、不挥发、对人体无害、对钢材无腐蚀性之气体。

但输送的气体不得含粘性物质，所含尘土及硬质颗粒物不大于150mg/m3，气体温度不得超过80℃。

4-72型离心通风机在我国是使用最早的风机，然而也是使用最普通的风机，从高层建筑到地下铁道，从锅炉鼓风到厂房换气，从北部边疆到南海之滨，从西部高原到东部边垂，随处可见。

型式从电机一端正视，凡叶轮按顺时针方向旋转者均称“右旋风机”，以“右”表示，反之则均称之为“左旋风机”，以左表示。

风机的出风口位置以机壳的出风口角度表示，4-72型风机No2.8~6在出厂时均做成一种型式，使用单位根据要求再安装成所需要的位置，订货时无须注明。

其中：No2.8出风口位置调整范围是0°~225°，间隔是45°；No3.2~6出风口调整范围是0°~225°，间隔是22.5°；No8~12出风口调整范围是0°~225°，间隔是45°；No16、20出风口角度制成固定的0°、90°、180°三种，不能调整，订货时需注明。

风机的传动方式有A、B、C、D四种：No2.8~5采用A式传动，No6既有A式传动又有C式传动，No8~12采用C、D式两种传动方式，No16~20采用B式传动。

如上述机号、传动方式、出口角度不能适应您的生产需要，我厂有能力为您改造或设计，直至您满意为止。

结构本风机No2.8A~6A主要由叶轮、机壳、进风口、电机等部分组成，No6C和No8~20除具有上述结构外，还有传动部分。

叶轮－由10个后倾机翼型叶片、曲线型轮盖和平板后盘组成，经动静平衡校正和超速运转实验，效率高，运转平稳可靠，空气性能良好。

机壳－用普通钢板焊接成蜗壳形整体。

进风口－制成整体结构，装于风机一侧，与轴向平行的截面为曲线形状，作用是能使气流顺畅进入叶轮，且损失较小。

4-72型离心通风机一、风机的分类风机按压力和作用分为通风机、鼓风机和压缩机。

通风机的排气压力较小，不超过0.015MPa；鼓风机的排气压力稍大不超过0.2MPa；压缩机的排气压力最高从1～100MPa以上。

风机按其工作原理可分为以下几种：1、离心风机，是气流轴向进入风机的叶轮后主要沿径向流动。

这类风机根据离心作用的原理制成，产品包括离心通风机、离心鼓风机和离心压缩机。

2、轴流风机，是与风叶的轴同方向的气流（即风的流向和轴平行），如电风扇，空调外机风扇就是轴流方式运行风机。

轴流式风机通常用在流量要求较高而压力要求较低的场合。

这类风机包括轴流通风机、轴流鼓风机和轴流压缩机。

3、回转风机回转风机是利用转子旋转改变气室容积而进行工作的。

常见的品种有罗茨鼓风机、回转压缩机。

4、斜流（混流）风机斜流（混流）风机风压系数比轴流风机高，流量系数比离心风机大。

填补了轴流风机和离心风机之间的空白。

同时具备安装简单方便的特点。

二、产品概述4-72型离心通风机在我国是使用最早的风机，然而也是使用最普遍的风机。

4-72型离心风机是一款常见的抽风机产品，由于其使用效率高，广泛用于工矿厂房和民用建筑、大型公共建筑、发电厂等场所，还可以作为空气处理设施、热风循环设施的配套设备。

目前市场上常用的有4-72-A式和4-72-C式两类别离心式风机。

4-72型离心风机为钢制离心风机，F4-72型离心风机为玻璃钢离心风机，B4-72型离心风机为防爆离心风机。

三、使用条件1、输送的介质要求：输送的介质应为空气或气体无腐蚀性、不易燃易爆、不含粘性物质的气体，气体内所含尘土及硬物颗粒含量不大于150mg/m3。

2、输送的介质温度：标准风机输送的介质温度不大于80℃，增加散热轮时风机可长期输送200℃以下的介质。

3、不能在完全封闭没有空气流动的空间作抽风使用，会形成负压增加电机负载。

四、使用范围一般工厂及大型建筑物的室内通风换气或输送空气及其它不自燃、不易爆、不挥发、对人体无害、对钢材无腐蚀性之气体。
