小小的集流器决定着离心风机的工作效率是否足够高，而对于一台离心风机而言，叶轮也是一个相当重要的小部件它也在无形中为离心风机的工作努力奋斗呢！叶轮的尺寸、形状等各方面因素都会对离心风机的工作性能、工作效率带来非常直接的影响。今天小编就带着问题叶轮是否是决定离心风机工作效率的关键？与大家共同探讨一下离心风机的另外一个小部件——叶轮。

The small collector determines whether the working efficiency of the centrifugal fan is high enough. For a centrifugal fan, the impeller is also a very important small part. It is also working hard for the work of the centrifugal fan! The size, shape and other factors of the impeller will have a very direct impact on the working performance and efficiency of the centrifugal fan. Today, Xiaobian has the question: is the impeller the key to determine the working efficiency of centrifugal fan? Discuss with you another small part of centrifugal fan - impeller.

叶轮顾名思义是个圆形带动离心风机叶片转动的部件，叶轮是由前盖、后盖、轮毂组成的。 离心风机叶轮的前盖有很多种形式比如：圆锥形前盘、平形前盘、圆弧形前盘等等。

As the name suggests, the impeller is a circular component that drives the blades of the centrifugal fan to rotate. The impeller is composed of a front cover, a rear cover and a hub. The front cover of centrifugal fan impeller has many forms, such as conical front plate, flat front plate, circular arc front plate and so on.

平盘的叶轮，制造起来相对其他形式是比较简单的，但是平形非常的不利于气流的流通，使离心风机的工作效率也会随之下降。圆锥形的叶轮和圆弧形的叶轮，制造起来要比平盘的叶轮复杂的多，不过他们的形状十分有利于气流的流通，这两个形式的叶轮强度也比较好，多方面的因素集合从而也就提高了离心风机的工作效率。

The manufacture of flat disc impeller is relatively simple compared with other forms, but the flat shape is very unfavorable to the flow of air, which will reduce the working efficiency of centrifugal fan. The manufacture of conical impeller and circular arc impeller is much more complex than that of flat disc impeller, but their shape is very conducive to the flow of air flow. The strength of these two forms of impeller is also relatively good, and the collection of various factors improves the working efficiency of centrifugal fan.

叶轮是否是决定离心风机工作效率的关键？

Is impeller the key to determine the working efficiency of centrifugal fan?

离心风机的叶轮直径和叶轮宽度决定了风机的流量和压力，叶轮宽度越窄，进出风口的面积也就越小，风机的转速一快离心风机的压力就越大，所以叶轮的尺寸也是决定离心风机是否效率更高的关键呢！

The impeller diameter and width of the centrifugal fan determine the flow and pressure of the fan. The narrower the impeller width is, the smaller the area of the air inlet and outlet is. The faster the speed of the fan is, the greater the pressure of the centrifugal fan is. Therefore, the size of the impeller is also the key to determine whether the centrifugal fan is more efficient!

叶轮按照一定的加压形式可以区分成单级加压风机、多级加压风机、双级加压风机。点的风机都是使用多级加压风机。什么叫多级加压风机呢？就是两个或者两个以上叶轮串联起来形成的风机叫做多级加压风机。

According to certain pressurization forms, the impeller can be divided into single-stage pressurization fan, multi-stage pressurization fan and two-stage pressurization fan. The fans at the point are multi-stage pressurized fans. What is multi-stage pressurized fan? The fan formed by two or more impellers in series is called multi-stage pressurized fan.
