對於離心風(fēng)機的使用用戶來說,磨損(sǔn)問題無時無處不在,那(nà)麽(me)離心風機在使用過程中會(huì)出現磨損分為多種(zhǒng)情況,主(zhǔ)要hi指軸承之間的磨(mó)損,再就是葉輪、整機的(de)磨損這些磨損現象嚴重的話會直接導致離心風機的使用效(xiào)果不能發揮出來,由於磨損的方(fāng)麵(miàn)比價多,我(wǒ)們在本章節主要以葉輪的(de)磨損問題出發點,為用戶尋找幾個能應對葉輪磨損問題的方法和技(jì)巧,以便能更(gèng)好(hǎo)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(gè)比較典型的方(fāng)法(fǎ),盡量將離心風機置於除塵器之(zhī)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(zhì)於除塵器之後均大大利(lì)於防止風機的磨損,表麵粘貼或焊接(jiē)陶瓷,將耐磨工程陶瓷利(lì)用高強度耐高溫膠粘劑或特殊焊接(jiē)工藝複合在風機(jī)葉(yè)片表麵上,該(gāi)技術(shù)要重點解(jiě)決防脫落(luò)問題。等離子堆焊,堆焊時葉片變形(xíng)大,而且反複焊接會(huì)導致葉麵(miàn)產生裂縫,易(yì)產(chǎn)生事故。對葉片表麵可以(yǐ)進(jìn)行滲碳,滲碳工藝(yì)難度大,實際滲碳時,滲碳層的部(bù)位和厚度要由(yóu)葉(yè)片厚度和(hé)磨損情況以及滲碳工藝決定。熱噴塗(tú),采用等離子(zǐ)噴塗方法或氧(yǎng)乙炔火焰,在葉片磨損表麵噴塗陶瓷(cí)或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.
減少葉輪磨損的方法還需要用戶從防腐蝕做起,很多時候風機的腐蝕會加重風機的磨損現象,因此如何(hé)在使用中減少風機的腐蝕現象,也是用戶使用風機(jī)的過程中需要研究的一個課題,保障風機的順利誰用僅僅從這些方麵來入(rù)手是遠遠不夠的,我們都知道風機能不能(néng)保持最長的使用效(xiào)果,和平時對風機的保養維護(hù)程度(dù)是分不開的,一個完善的保(bǎo)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.
