對於離心風機的使用用戶來說，磨損問題無（wú）時（shí）無處不在，那麽離心風機在使用過程中會出現磨損分為多（duō）種情（qíng）況，主要hi指軸承之（zhī）間的磨損，再就（jiù）是（shì）葉輪、整機的磨損這些磨損（sǔn）現象（xiàng）嚴重的（de）話會直接導致離（lí）心風機的使用效果不能發揮出來，由於磨損的方（fāng）麵比價多，我們在本章節主要以葉輪的磨損問題出發點，為用戶尋（xún）找幾個能（néng）應對葉輪磨損問題的（de）方法（fǎ）和技巧，以便能更好的使用風機。
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（bǐ）較典型的方法，盡量將離心（xīn）風機置於除塵（chén）器之後，如：風機置於增濕塔或管道增濕之後，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磨損，表麵粘貼或焊接陶瓷，將耐磨工程（chéng）陶瓷利用高強度耐高溫膠粘劑或特（tè）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，堆焊時葉片（piàn）變（biàn）形大，而且反複焊接會導致葉麵產生裂縫，易產生事故。對（duì）葉片表麵可以進行滲碳，滲碳工藝難度大，實際滲（shèn）碳時，滲碳層的部位和厚度要由葉片厚度和磨損情況（kuàng）以及滲碳工藝決定。熱噴塗，采用等（děng）離子噴塗方法或（huò）氧乙炔火焰，在葉片磨損表（biǎo）麵噴塗陶瓷或碳化鎢或者噴焊鎳基（jī）+碳化鎢合金。
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用戶從防腐蝕（shí）做起，很多時候風機（jī）的腐蝕（shí）會加重風機（jī）的磨損現象，因此如何在使用中減少風機（jī）的腐蝕現（xiàn）象，也是用戶使用風（fēng）機的過程中需要研究的（de）一個課題，保障（zhàng）風機的順利誰用僅僅從這些（xiē）方麵來入手是遠（yuǎn）遠不夠的，我們都（dōu）知道風機能不能保持最長的使用效果，和平時對風機的保養維護程度是分不開的，一個完善（shàn）的保養方案是用戶必須（xū）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.
