對於離心風機（jī）的使用用戶來說，磨損問題無時（shí）無處不在（zài），那麽離心風機（jī）在（zài）使用過程中會出現磨（mó）損分為多種情況，主要hi指（zhǐ）軸承之間的磨損，再就是葉輪、整機的磨損（sǔn）這些磨損（sǔn）現象嚴重的話會直接導致離（lí）心風（fēng）機的使用效果不能發揮出（chū）來（lái），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題出（chū）發點，為用戶尋找幾個能應對葉輪磨損（sǔn）問題的方法和技巧，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（gōng）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（guǎn）道增濕之後，烘幹熱源抽（chōu）風機置於除塵器之後均大大利於防（fáng）止風機的磨（mó）損，表麵粘貼或焊（hàn）接陶瓷，將（jiāng）耐磨工（gōng）程陶瓷利用高強（qiáng）度耐高溫膠粘劑或特殊焊接工藝複合在風機葉片（piàn）表麵上，該技術要重點解（jiě）決防脫落問題。等離子堆焊，堆焊（hàn）時葉片變形大，而且反複焊接會導致葉麵產（chǎn）生裂縫，易產生（shēng）事故。對葉片（piàn）表麵可以進行滲碳（tàn），滲碳工藝難度大，實際滲碳時，滲（shèn）碳層的部位和厚度要由葉片厚度和磨損情況以及滲（shèn）碳工藝決定（dìng）。熱噴塗，采用等離子噴塗方法或氧乙（yǐ）炔火焰，在葉片磨損表麵噴塗陶瓷或（huò）碳化鎢或者噴焊鎳基+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（shǎo）葉輪磨損的方法還需要用戶從防腐（fǔ）蝕做（zuò）起，很多時候風機的腐蝕會加重風機的磨損現象，因此如何在使用中減少風機的腐蝕（shí）現象，也是（shì）用戶使用風（fēng）機的過程中需要研究的一個課（kè）題（tí），保障（zhàng）風機的順利（lì）誰用僅僅從這些方麵來入手是（shì）遠遠不夠的（de），我們都知道風機能不能保持（chí）最長的使用效果，和平時對風機的保養（yǎng）維護程度是分不開的，一個完善的保（bǎo）養（yǎng）方案是用（yòng）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.
