造成离心式风机叶轮磨损的因素有很多，而且多数是由于多重机理综合作用的结果，这会影响离心式风机的整体使用效果，因而，进行叶轮磨损的措施非常必要。下面，就为大家做个简要介绍。

There are many factors causing impeller wear of centrifugal fan, and most of them are the result of multiple mechanisms, which will affect the overall use effect of centrifugal fan. Therefore, it is necessary to take measures for impeller wear. Now, let's make a brief introduction.

针对不同的磨损形式，可以将防磨损措施分为以下几种为：

According to different wear forms, anti-wear measures can be divided into the following categories:

1、对叶片表面进行处理

1. Treat the blade surface

对离心式风机叶片表面可以进行渗碳、等离子堆焊、喷涂硬质合金、粘贴陶瓷片处理。这些方法的共同优点是增加了叶片表面的硬度，从而在一定程度上提高了叶片的耐磨性，但各种方法均存在各自的缺点。渗碳工艺难度大，实际渗碳时，渗碳层的部位和厚度要由叶片厚度和磨损情况以及渗碳工艺决定；堆焊时叶片变形大，而且反复焊接会导致叶面产生裂缝，易产生事故；喷涂时涂层的厚度很难确定好；粘贴陶瓷片的效果比较好，但价格高。

The surface of centrifugal fan blade can be carburized, plasma overlaid, sprayed with cemented carbide and pasted with ceramic. The common advantage of these methods is to increase the hardness of the blade surface, so as to improve the wear resistance of the blade to a certain extent, but each method has its own shortcomings. Carburizing process is very difficult. In actual carburizing, the position and thickness of carburized layer are determined by blade thickness, wear condition and carburizing process; During surfacing welding, the blade deformation is large, and repeated welding will lead to cracks on the blade surface, which is easy to cause accidents; It is difficult to determine the thickness of coating during spraying; The effect of pasting ceramic pieces is better, but the price is high.

2、表面喷涂耐磨涂层

2. Wear resistant coating on the surface

这种方法操作简单，成本低，但涂层磨损快，一次大约使用3—5个月。

This method is simple, low cost, but the coating wear fast, about 3-5 months at a time.

3、改进叶片结构

3. Improving blade structure

将叶片工作面加工成锯齿状、变中空叶片为实心叶片、叶片加焊防磨块等方法，这些都可以在一定程度上降低叶轮的磨损。

The impeller wear can be reduced to a certain extent by processing the blade working face into serrated shape, changing the hollow blade into solid blade and welding the blade with anti-wear block.

4、前置防磨叶栅

4. Front anti-wear cascade

在离心式风机易磨损的地方安装防磨叶栅后，可以阻止粒子向后盘及叶根处流动，从而将粒子的集中磨损转化为均匀磨损，提高了叶轮的耐磨性，延长了风机的使用寿命。

After installing the anti-wear cascade in the place where the centrifugal fan is easy to wear, it can prevent the particles from flowing to the back disk and the blade root, so as to transform the concentrated wear of particles into uniform wear, improve the wear resistance of the impeller and prolong the service life of the fan.

5、改善气动设计

5. Improving aerodynamic design

合理选用离心式风机进风口形状，设计时应保证叶轮小入口相对速度，尽量降低通风机的转数，选择适当的叶轮流道形状，使叶片进口到出口的弧度的曲率半径由小渐大，这样能减少固体颗粒与叶片的撞击机会。

Reasonable selection of centrifugal fan inlet shape, design should ensure that the impeller small inlet relative speed, try to reduce the number of fan revolutions, select the appropriate impeller runner shape, make the blade inlet to outlet curvature radius from small to large, so as to reduce the chance of solid particles and blade collision.

以上就是关于陕西离心式风机厂家的叶轮磨损的措施，大家一定要牢记，这可以大大的延长离心式风机的使用寿命哦。

The above is about Shaanxi centrifugal fan manufacturers impeller wear measures, we must bear in mind, this can greatly extend the service life of centrifugal fan oh.
