前后傾葉片離心風機的效率、噪音、功耗和尺寸比較轉速C大于后傾葉片，所以氣流的動能在螺旋腔內轉化為壓力能。損耗也較大，因此用于克服系統阻力的靜壓頭占比較小。后傾葉片傳遞給氣流的速度C較小，因此氣流在轉換中的損失較小，因此用于克服系統阻力的靜壓頭占很大比例，下面一起來了解一下選擇離心引風機設備要考慮哪些因素？

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、考慮耗電量；由上可知風機效率直接影響風機軸功率的大小，后葉風機效率高，風機所需軸功率小，耗電量少。前傾葉片風機效率低，風機所需軸功率大耗電較多。由于前傾葉片傳遞給氣流的速度大于后傾葉片，因此在轉換過程中氣流的損失也為越大，氣流與機殼碰撞的速度也越大，且后傾葉片的通道曲率平緩，氣流相對順暢，因此前傾式葉片風扇比后傾式葉片風扇噪音更大。

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、考慮機身尺寸；經常用風扇的流量系數和壓力系數的乘積來衡量風扇機身的尺寸，因此前葉片風扇小于后葉片體。后傾葉片風機中的通道一般是逐漸擴大的，前傾葉片的通道擴大較為溫和。此外后傾葉片的曲率小于前傾葉片的曲率，因此在后傾葉片通道中流動的氣流的水力損失小于前傾葉片的水力損失。主要工作參數是風量，輸出壓力隨管道和負載而變化風量變化很小。轉鼓風機為變容壓縮，其主要特點是低轉速、低振動、效率高、更節能。

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.

總而言之，選擇離心引風機設備要考慮的因素有考慮耗電量和機身尺寸，后傾葉片的風扇比前傾葉片的風扇效率更高。通過對前傾和后傾葉片風機的分析，認為在選擇風機時，除了風機本體的尺寸，設備采購成本，占地面積等。除了比較初期投資外，還要對風機效率、功耗等運行管理成本有足夠的了解。

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.
