轴流风机和离心风机如何区分
How to Distinguish Axial Fan and Centrifugal Fan
风机大类里面两种不同的产品是轴流风机和离心风机，这两种产品主要功能也都得对环境内空气进行通风换气的设备，下面具体看下轴流风机和离心风机如何区分？
Two different products in fan category are axial flow fan and centrifugal fan. The main functions of these two products are also equipments for ventilating and ventilating the air in the environment. Let's see how the axial flow fan and centrifugal fan can be distinguished.
一、轴流风机和离心风机排风方向不同：轴流风机的排风方向是沿着轴的方向直排，风机的进风口和排风口是在一条轴平行线上，离心风机的排风方向是垂直于进风口方向的，可以实现360度指定方向排风。
First, the exhaust direction of the axial fan is different from that of the centrifugal fan: the exhaust direction of the axial fan is straight along the axis direction, the inlet and outlet of the fan are on an axis parallel line, and the exhaust direction of the centrifugal fan is perpendicular to the direction of the intake, which can achieve 360 degree directional exhaust.
二、轴流风机和离心风机安装难度不同：轴流风机的安装比较简单，一般是直接安装在墙上或者连接风管。离心风机安装比较复杂。
2. The installation difficulty of axial-flow fan and centrifugal fan is different: the installation of axial-flow fan is relatively simple, usually directly installed on the wall or connected to the air duct. The installation of centrifugal fan is complicated.
三、轴流风机和离心风机风量和风压的不同：轴流风机的风量风压比较小，基本上没什么风压，而离心风机的风量风压都比较大，如果是管道弯头多，抽风距离和送风距离都比较远，管道阻力大，就必须使用离心风机。
3. The difference of air volume and pressure between the axial fan and the centrifugal fan: the air volume and pressure of the axial fan are relatively small, and basically there is no air pressure, while the air volume and pressure of the centrifugal fan are relatively large. If there are many elbows in the pipeline, the distance between the exhaust and the supply air is relatively long, and the resistance of the pipeline is large, the centrifugal fan must be used.
