工厂离心式风机目前是工业领域中不可缺少的一种机器，许多地方如工厂、矿井、隧道、冷却塔等等这些地方都有它的身影，它可以有效的进行排尘和冷却，工业领域现在是我国着重发展的一个方向，那对离心式风机的需求也是越来越大，在使用过程中大家都会反映一个问题，那就是在使用中离心式风机的叶片经常会出现磨损的现象，这种现象也是大家比较头疼的，那该如何去改善叶片的磨损状况呢，跟随小编了解一下吧。

At present, centrifugal fan in factory is an indispensable machine in the industrial field. It is found in many places, such as factories, mines, tunnels, cooling towers and so on. It can effectively discharge dust and cool. Industrial field is now a development direction in China, and the demand for centrifugal fan is also growing, In the use of the process, we will reflect a problem, that is, in the use of centrifugal fan blades often appear wear phenomenon, this phenomenon is also a headache, then how to improve the blade wear condition, follow Xiaobian to understand it.

1、叶片表面的处理：

1. Blade surface treatment:

渗碳、等离子堆焊、喷涂硬质合金和粘贴陶瓷片。这些方法可以在一定程度上来增加叶片表面的硬度，从而提高叶片的耐磨性。然而，所有类型的处理过程都是困难的并且难以操作，或者说价格高因素降低了处理叶片的可行性。

Carburizing, plasma surfacing, spraying cemented carbide and sticking ceramic sheet. These methods can increase the hardness of the blade surface to a certain extent, so as to improve the wear resistance of the blade. However, all types of treatment processes are difficult and difficult to operate, or high price factors reduce the feasibility of blade treatment.

2、表面喷涂耐磨涂层：

2. Wear resistant coating is sprayed on the surface

还是比较推荐使用这种方法，这种方法操作比较简单，成本低，但是涂层磨损快，所以一般一个季度就得重新对表面去喷涂耐磨涂层。这种方法是比较作用是比较短的。

It is recommended to use this method. This method is relatively simple, low cost, but the coating wears fast, so it is generally necessary to re spray the wear-resistant coating on the surface in a quarter. This method is comparative and its effect is relatively short.

3、改进叶片结构：

3. Improved blade structure:

通过修改叶片结构可以减少磨损，比如将叶片工作面加工成锯齿状，将空心叶片改为实心刀片，将叶片家防磨块焊接等方法是都可以的。

The wear can be reduced by modifying the blade structure, such as processing the blade working face into serrated shape, changing the hollow blade into solid blade, and welding the blade anti-wear block.

4、前置磨叶栅：

4. Pre grinding cascade:

将防磨叶栅安装在易磨损的地方后，可以防止颗粒流向后盘和叶根，使颗粒转化的集中磨损为均匀磨损，提高了叶轮的耐磨性，延长了工厂离心式风机的使用年限。

After the anti-wear cascade is installed in the place easy to wear, the particles can be prevented from flowing to the back disc and blade root, the concentrated wear of particles can be transformed into uniform wear, the wear resistance of impeller is improved, and the service life of centrifugal fan in the factory is extended.

5、使用比较有效果的除尘装置：

5. Using effective dust removal device:

离心式风机运行环境中的灰尘也会加剧风机磨损。建议使用除尘装置净化风机的工作环境，以减少离心式风机的磨损。

The dust in the operation environment of centrifugal fan will also aggravate the fan wear. It is suggested to use dust removal device to purify the working environment of the fan, so as to reduce the wear of the centrifugal fan.

以上就是为大家介绍的工厂离心式风机叶片该如何去改善和防护，总体来说是分为以上五点，大家可以对叶片的表面进行处理或者对叶片的结构去解决，还有就是可以喷耐磨喷涂，从而减少叶片的磨损状况，大家也要时刻的去注意叶片的使用情况，防止使用过程中因为叶片问题出现停机的状况。

The above is to introduce how to improve and protect the centrifugal fan blades in the factory. Generally speaking, it is divided into the above five points. You can deal with the surface of the blades or solve the structure of the blades. In addition, you can spray wear-resistant coating to reduce the wear condition of the blades. You should always pay attention to the use of the blades, To prevent the use of blade problems in the process of shutdown.
