[Khoom Taw Qhia] Tungsten carbide bushes: txhim khu kev qha hnav-resistant daws teeb meem nyob rau hauv hnyav ua haujlwm tej yam kev mob

Ua ib qho tseem ceeb rau kev tiv thaiv lub twj tso kua mis, qhov ruaj khov ntawm lub tes tsho ntawm lub tes tsho ncaj qha cuam tshuam rau kev ruaj khov ntawm cov khoom siv khiav lag luam thiab cov nqi txij nkawm. Ua cov khoom siv tseem ceeb rau kev tswj cov kua dej, cov twj tso kua mis siv dav hauv ntau qhov chaw xws li kev tsuas, kev lag luam tshuaj lom neeg, lub zog, metallurgy, thiab lwm yam. Txawm li cas los xij, thaum ntsib cov khoom siv abrasive xws li slurry thiab av nkos, lossis cov kua corrosive muaj zog xws li acid, alkali, thiab ntsev, lossis cov xwm txheej ua haujlwm hnyav xws li kub thiab siab siab, cov hlau tsis xeb, cov hlau quenched, thiab lwm yam khoom siv feem ntau tsis muaj zog, yooj yim hnav, xeb, deformation, thiab lwm yam teeb meem, ua rau cov twj tso kua mis ua haujlwm tsawg dua, foob xau, hloov pauv ntau zaus, thiab nce lub sijhawm tsis ua haujlwm thiab cov nqi txij nkawm.

Qhov ciam teb ua tau zoo ntawm cov ntaub ntawv tab tom dhau los ua qhov teeb meem tseem ceeb uas txwv tsis pub muaj kev ntseeg siab thiab lub neej ntev ntawm cov twj tso kua mis thiab cov khoom siv valve.

Tungsten carbide bushestau dhau los ua qhov kev xaiv txhim khu kev qha rau kev hloov kho rau cov xwm txheej ua haujlwm hnyav vim lawv cov khoom siv ruaj khov dua.

TSIS MUAJ.01Cov teeb meem ntawm kev ua haujlwm hauv kev lag luam twj tso kua mis thiab lub valve

Cov xwm txheej ua haujlwm ntawm cov khoom siv yog qhov nyuaj thiab sib txawv, thiab cov xwm txheej thov sib txawv ua rau muaj kev xav tau sib txawv tab sis sib npaug ntawm cov ntaub ntawv:

1.Cov xwm txheej hnav abrasive:Thaum cov khoom siv xws li cov twj tso kua dej thiab cov twj tso kua av thauj cov khoom uas muaj cov khoom khov, qhov saum npoo ntawm lub tes tsho ncej raug kev puas tsuaj ntau zaus thiab kev hnav tsis zoo. Cov khoom siv hlau ib txwm hnav sai heev nyob rau hauv cov xwm txheej zoo li no, ua rau muaj kev saib xyuas ntau zaus thiab kev poob loj heev vim yog kaw cov khoom siv.

2.Muaj zog xeb：Cov twj tso kua tshuaj, cov twj tso kua dej khib nyiab, thiab lwm yam khoom siv feem ntau kov cov khoom siv corrosive xws li acids, alkalis, thiab ntsev. Txawm hais tias cov khoom siv stainless hlau muaj qee qhov kev tiv thaiv corrosion, lawv tseem muaj feem yuav muaj pitting corrosion, kev ntxhov siab corrosion cracking, thiab lwm yam teeb meem hauv qhov kub thiab txias thiab qhov chaw muaj concentration siab.

3.Kub siab ua haujlwm mob:Qhov kub ua haujlwm ntawm cov khoom siv xws li cov twj tso kua roj kub thiab cov twj tso kua kub siab feem ntau ncav cuag 300-400 ° C. Tom qab qhov kub thiab txias no, kev ua haujlwm ntawm cov hlau zoo tib yam poob qis, qhov nyuaj txo qis, thiab qhov deformation nce ntxiv, ua rau muaj kev phom sij rau kev nyab xeeb ntawm kev ua haujlwm ntawm cov khoom siv.

TSIS MUAJ.02Cov txiaj ntsig ntawm cov khoom siv hlau nplaum

Cov teeb meem feem ntau nrog cov tes tsho ncej ib txwm muaj

1. Kev puas tsuaj sai sai, kev ua haujlwm dav dua, thiab kev ua haujlwm ntawm lub twj tso kua mis txo qis;

2. Yooj yim rau xeb thiab pitting, ua rau muaj qhov xau nruab nrab;

3. Kev ua haujlwm txo qis nyob rau hauv qhov kub siab, ua rau nws yooj yim deformation thiab jamming;

4. Hloov ntau zaus, ua haujlwm ntau, khoom seem, thiab nqi sijhawm tsis ua haujlwm.

Tungsten carbide tes tshoyog ib qho kev daws teeb meem uas tsis yooj yim hnav rau cov khoom siv twj tso kua mis hauv qab kev ua haujlwm hnyav.

1.Kev tiv thaiv zoo hnav:Nws qhov HRA hardness tuaj yeem ncav cuag ntau dua 90, thiab nws qhov kev tiv thaiv hnav yog ntau dua 5 npaug ntawm cov hlau ib txwm. Lub neej ua haujlwm ntawm cov khoom siv ntev dua, thiab qhov zaus ntawm kev hloov pauv tuaj yeem txo qis;

2.Kev tiv thaiv corrosion thiab stability:Muaj peev xwm ua siab ntev rau ntau yam kua qaub thiab alkaline media, tsim nyog rau cov xwm txheej corrosive xws li dej phwj, dej hiav txwv, kua tshuaj, thiab lwm yam, txo qhov kev pheej hmoo ntawm corrosion thiab to;

3.Kev ua tau zoo ntawm qhov kub thiab txias:Kev ua haujlwm ruaj khov tuaj yeem tswj tau nyob rau hauv ib puag ncig ntawm 500-600 ℃, tsim nyog rau cov khoom siv xws li cov twj tso kua roj kub, cov twj tso kua kub siab, cov twj tso kua condenser, thiab lwm yam;

4.Kev tiv thaiv kev cuam tshuam zoo thiab kev tawv:Muaj peev xwm tiv taus kev co thiab dej ntaus thaum lub sijhawm ua haujlwm ntawm cov khoom siv, txo qhov tshwm sim ntawm kev ua tsis tiav ntawm cov khoom, kev hloov pauv, thiab kev sib tsoo.
