离心风机防磨处理

离心风机在使用中叶片磨损现象经常出现，如何才能改善离心风机这种磨损情况。下面就由鑫风风机厂家为大家介绍几种防磨措施：
The blade wear of centrifugal fan often occurs in use. How to improve the wear of centrifugal fan. The following is the introduction of several anti abrasion measures by Xinfeng fan manufacturer:
1、对叶片表面进行处理：对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。这些方法均可以在一定程度上增加叶片表面的硬度，从而提高叶片的耐磨性，不过各种处理工艺均存在一定难度，不易操作或是价格高等因素降低了对叶片进行处理的可行性。
1. Treatment of blade surface: carburizing, plasma surfacing, spraying cemented carbide and sticking ceramic chips can be applied to the blade surface. 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, there are certain difficulties in various treatment processes, which reduce the feasibility of the treatment of the blade due to the factors of difficult operation or high price.

2、表面喷涂耐磨涂层：这种方法是比较建议的，操作起来简单，成本也不高，但涂层磨损很快，大概需要3-5个月就重新进行表面耐磨涂层的喷涂。
2. Surface spray wear-resistant coating: this method is relatively recommended. It is simple to operate and low in cost. However, the coating wear is very fast. It will take about 3-5 months to spray the surface wear-resistant coating again.
3、改进叶片结构：可以通过对叶片结构的改造来降低磨损，比如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。
3. Improvement of blade structure: the blade structure can be modified to reduce wear, such as machining the blade working face into serration, changing the hollow blade into solid blade, adding welding anti-wear block to the blade, etc.
4、前置防磨叶栅：在最易磨损处安装防磨叶栅后，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，延长风机的使用寿命。
4. Front anti-wear cascade: after the anti-wear cascade is installed at the most easily worn place, it can prevent particles from flowing to the back disk and blade root, so as to transform the concentrated wear of particles into uniform wear, improve the wear resistance of impeller, and extend the service life of fan.
5、使用高-效除尘装置：离心风机运行环境中的粉尘也会加剧风机磨损，建议采用除尘装置，净化风机工作环境，以降低离心风机磨损。
5. Use of high efficiency dedusting device: the dust in the operation environment of centrifugal fan will also aggravate the fan wear. It is recommended to use dedusting device to clean the working environment of fan to reduce the wear of centrifugal fan.
