對於離心風機的使用用戶來說，磨損問題無時無處不在，那麽離（lí）心風機在使用過程中會出現磨損分為多種情況（kuàng），主要hi指軸承之間的磨損，再就是葉輪、整機的磨損這些磨損（sǔn）現（xiàn）象（xiàng）嚴重（chóng）的話（huà）會直接（jiē）導致離心風機的使用效果不能發揮出來，由於磨損的方麵比價多，我們在本章節主要以葉輪的磨損問（wèn）題出發點，為用戶尋找幾個能應對葉輪磨損問題的方法和技巧，以便能更好的使（shǐ）用風機。
For the use of centrifugal fans users, wear problems are ubiquitous, then the centrifugal fans in the use of the process of wear can be divided into a variety of situations, mainly hi refers to the wear between bearings, and then impeller, machine wear these serious wear phenomenon will directly lead to the use of centrifugal fans can not play a role In this chapter, we mainly start with the problem of impeller wear and tear, and find several methods and skills to deal with the problem of impeller wear and tear for users, so that we can better use the fan.
改進工藝路線是一個比較典型的方法，盡量將離心風機置於除塵器之後，如：風機置於增濕塔或管道（dào）增濕之後，烘幹熱源抽風機置於（yú）除塵器（qì）之後均大大利於防止風機的（de）磨損，表（biǎo）麵粘貼或焊接陶（táo）瓷，將（jiāng）耐磨工程（chéng）陶瓷利用高強度耐（nài）高溫膠粘劑或特殊焊接工藝複合在風（fēng）機葉片表麵上，該技術要重點解決防脫落問題。等離子堆焊，堆焊時（shí）葉片（piàn）變形大，而且反複焊接會導致葉麵（miàn）產生裂縫，易產生事故。對葉片表麵可以進行滲碳，滲碳工（gōng）藝難度大，實際（jì）滲（shèn）碳時，滲碳層的部位和厚度要由葉片厚度（dù）和磨損情況以及滲（shèn）碳工藝決定。熱噴塗，采用等離子噴塗方法或氧乙炔火焰，在葉片磨損表麵噴塗（tú）陶（táo）瓷或碳化鎢或者噴焊鎳基+碳化鎢（wū）合金。
Improving the technological route is a typical method. Putting the centrifugal fan behind the dust collector as far as possible, such as: the fan after humidifying tower or pipeline, drying heat source fan after the dust collector are greatly beneficial to prevent the fan from wearing, surface pasting or welding ceramics, wear-resistant engineering ceramics will use high strength and resistance. High temperature adhesives or special welding processes are combined on the surface of the fan blades, and the anti-shedding problem should be solved. Plasma surfacing welding, surfacing blade deformation, and repeated welding will lead to cracks on the blade surface, easy to cause accidents. It is difficult to carburize the blade surface. The position and thickness of carburizing layer are decided by the blade thickness, wear and carburizing process. Thermal spraying, using plasma spraying method or oxyacetylene flame, spraying ceramic or tungsten carbide or spraying welding nickel-based + tungsten carbide alloy on blade wear surface.
減少葉輪磨損的方法還需要（yào）用戶從防腐蝕做起，很多時候風機的（de）腐蝕會加（jiā）重風機的磨損現象，因此如何在使用中減少風機的腐蝕現象，也是用戶（hù）使用風機（jī）的過程（chéng）中需要研究的一個課題，保障風機的順利誰用僅僅（jǐn）從這些方麵來入手是遠遠不夠的，我們都（dōu）知（zhī）道風（fēng）機（jī）能不能保持最長的使用效果，和平時對風機的保（bǎo）養維護程度是分不開的，一個完善的保養方案是用戶必須要具備的。
The method of reducing impeller wear also needs the user to start from anticorrosion. In many cases, the corrosion of the fan will aggravate the wear phenomenon of the fan. So how to reduce the corrosion phenomenon of the fan in use is also a subject that the user needs to study in the process of using the fan. Hand is far from enough, we all know whether the fan can maintain the longest effect, and peacetime maintenance of the fan is inseparable, a perfect maintenance program is the user must have.
