任何金属都会受外界的因素从而引起被腐蚀的问题，方然，风机也不例外，风机使用时间长了之后或多或少会出现腐蚀现象，那么当我们遇到风机腐蚀情况出现时，需要采取哪些措施来应对?接下来，陕西离心式风机厂家来为大家分享一下预防风机腐蚀的三大因素。

Any metal will be corroded by external factors. However, the fan is no exception. After the fan has been used for a long time, corrosion will appear more or less. So when we encounter the corrosion of the fan, what measures need to be taken to deal with it? Next, Shaanxi centrifugal fan manufacturers to share with you about the prevention of fan corrosion of the three factors.

1、 风机表面防护

1. Fan surface protection

控制腐蚀的一个基本思路就是隔绝腐蚀环境。在离心式风机设计中，经常采用表面处理的办法，如法兰、镀锌、镀铬、化学镀层等办法，这些方法在许多环境中是有效的，但对于旋转零件，需要注意一个重要的现象:基体材料与镀层是两种材料，其线膨胀系数是不同的，将在旋转件弹性变形时产生不一样的变形量，从而造成大量的微裂纹的产生;若前述现象的存在，将加速腐蚀形成。因此，对于旋转零件的表面防护方法，应谨慎采用。

A basic idea of corrosion control is to isolate the corrosive environment. In the design of centrifugal fan, surface treatment methods are often used, such as flange, zinc plating, chromium plating, chemical plating and so on. These methods are effective in many environments, but for rotating parts, an important phenomenon needs to be noted: the matrix material and coating are two kinds of materials, and their linear expansion coefficients are different, The results show that the elastic deformation of the rotating parts will produce different deformation, resulting in a large number of microcracks; If the above phenomena exist, the formation of corrosion will be accelerated. Therefore, the surface protection method of rotating parts should be used carefully.

2、选对风机材质

2. Select the right material of fan

因为不同的物料及分离要求，需要选用不同的离心式风机机型。机型及主参数确定后，根据不同材料在不同环境中的耐腐蚀性能，综合其理化特性，性价比等诸多因素，从基本面上确定强度零件材料。从材料本身来看，它针对的目标物料是安全的。

Because of different materials and separation requirements, different centrifugal fan models need to be selected. After the model and main parameters are determined, according to the corrosion resistance of different materials in different environments, the physical and chemical characteristics, cost performance and many other factors, the strength parts materials are determined from the basic plane. From the material itself, the target material is safe.

3、风机的机构设计

3. Mechanism design of fan

一个好的设计能延长设备使用寿命，确保设备的安全性，对于结构设计， 容易加速腐蚀的设计缺陷是应力集中倾向和缝隙环境，有时尽管金属浸泡溶液中，腐蚀率较小;但形成缝隙，由于内部溶液的化学和电化学状态发生了变化，将引起严重的缝隙腐蚀。

A good design can prolong the service life of the equipment and ensure the safety of the equipment. For the structural design, the design defects that are easy to accelerate corrosion are the tendency of stress concentration and crevice environment. Sometimes, although the metal is immersed in the solution, the corrosion rate is small; However, the formation of crevice will cause serious crevice corrosion due to the change of chemical and electrochemical state of internal solution.
