前后倾叶片离心风机的效率、噪音、功耗和尺寸比较转速C大于后倾叶片，所以气流的动能在螺旋腔内转化为压力能。损耗也较大，因此用于克服系统阻力的静压头占比较小。后倾叶片传递给气流的速度C较小，因此气流在转换中的损失较小，因此用于克服系统阻力的静压头占很大比例，下面一起来了解一下选择离心引风机设备要考虑哪些因素？

The efficiency, noise, power consumption and size comparison speed c of forward and backward inclined blade centrifugal fan is greater than that of backward inclined blade, so the kinetic energy of air flow is converted into pressure energy in the spiral cavity. The loss is also large, so the proportion of static head used to overcome system resistance is relatively small. The speed c transmitted by the backward inclined blade to the air flow is small, so the loss of air flow in the conversion is small, so the static pressure head used to overcome the system resistance accounts for a large proportion. Let's find out what factors should be considered in the selection of centrifugal induced draft fan equipment?

1、考虑耗电量；由上可知风机效率直接影响风机轴功率的大小，后叶风机效率高，风机所需轴功率小，耗电量少。前倾叶片风机效率低，风机所需轴功率大耗电较多。由于前倾叶片传递给气流的速度大于后倾叶片，因此在转换过程中气流的损失也为越大，气流与机壳碰撞的速度也越大，且后倾叶片的通道曲率平缓，气流相对顺畅，因此前倾式叶片风扇比后倾式叶片风扇噪音更大。

1. Consider power consumption; It can be seen from the above that the fan efficiency directly affects the shaft power of the fan. The rear blade fan has high efficiency, small shaft power required by the fan and low power consumption. The efficiency of forward inclined blade fan is low, the shaft power required by the fan is large, and the power consumption is more. Because the speed transmitted by the forward inclined blade to the air flow is greater than that of the backward inclined blade, the greater the loss of air flow in the conversion process, the faster the collision between the air flow and the casing, and the channel curvature of the backward inclined blade is gentle and the air flow is relatively smooth. Therefore, the noise of the forward inclined blade fan is greater than that of the backward inclined blade fan.

2、考虑机身尺寸；经常用风扇的流量系数和压力系数的乘积来衡量风扇机身的尺寸，因此前叶片风扇小于后叶片体。后倾叶片风机中的通道一般是逐渐扩大的，前倾叶片的通道扩大较为温和。此外后倾叶片的曲率小于前倾叶片的曲率，因此在后倾叶片通道中流动的气流的水力损失小于前倾叶片的水力损失。主要工作参数是风量，输出压力随管道和负载而变化风量变化很小。转鼓风机为变容压缩，其主要特点是低转速、低振动、效率高、更节能。

2. Consider the size of the fuselage; The product of the flow coefficient and pressure coefficient of the fan is often used to measure the size of the fan body, so the front blade fan is smaller than the rear blade body. The passage in the backward inclined blade fan is generally gradually expanded, and the passage expansion of the forward inclined blade is relatively mild. In addition, the curvature of the backward inclined blade is less than that of the forward inclined blade, so the hydraulic loss of the air flow flowing in the backward inclined blade channel is less than that of the forward inclined blade. The main working parameter is the air volume. The output pressure changes with the pipeline and load, and the air volume changes very little. The drum fan is variable volume compression, which is mainly characterized by low speed, low vibration, high efficiency and more energy saving.

总而言之，选择离心引风机设备要考虑的因素有考虑耗电量和机身尺寸，后倾叶片的风扇比前倾叶片的风扇效率更高。通过对前倾和后倾叶片风机的分析，认为在选择风机时，除了风机本体的尺寸，设备采购成本，占地面积等。除了比较初期投资外，还要对风机效率、功耗等运行管理成本有足够的了解。

In a word, the factors to be considered in selecting centrifugal induced draft fan equipment include power consumption and body size. The fan with backward inclined blade is more efficient than that with forward inclined blade. Through the analysis of forward inclined and backward inclined blade fans, it is considered that when selecting fans, in addition to the size of fan body, equipment procurement cost, floor area, etc. In addition to the initial investment, it is also necessary to have a sufficient understanding of the operation and management costs such as fan efficiency and power consumption.
