Kev lag luam tshuaj lom neeg yog kev lag luam nrog ib puag ncig hnyav, cov khoom siv xws li cov kav dej thiab cov li qub ua lub luag haujlwm tseem ceeb hauv kev lag luam tshuaj niaj hnub.Valves muaj kev sib tw los ntawm ib puag ncig hnyav hauv kev xa cov raj xa dej xws li hmoov, granules, thiab slurries, thiab feem ntau ua rau lub valve hnav thiab tsis ua haujlwm.Yog li ntawd, peb yuav tsum tau siv cov khoom siv muaj zog-resistant, corrosion-resistant raws li cov khoom siv raw ntawm cov khoom siv valve, kom lub valve muaj lub neej ntev kev pab cuam, thiab cemented carbide yog qhov kev xaiv zoo tshaj plaws.Zhuzhou Chuangrui Cemented Carbide Co., Ltd. yuav qhia rau koj vim li cas ib qho tseem ceeb sintered cemented carbide yuav tsum tau xaiv los ua cov khoom siv rau li qub thiab cov khoom siv hauv cov kav dej hauv kev lag luam tshuaj.
Hauv kev lag luam thee chemical, av nkos thiab lwm cov khoom siv thauj mus los, lub sealing ib feem ntawm lub valve tsis yog tsuas yog yuav tsum tau zawv zawg kev sib txhuam thiab hnav ntawm lub sealing auxiliary qhov chaw, tab sis kuj yuav tiv taus qhov kev kub ceev ntawm cov roj-khoom duplex. sib tov nrog kub thiab siab hardness, raws li zoo raws li lub flashing thiab cavitation tshwm sim los ntawm high-pressure kua, uas ua rau kev puas tsuaj thiab aggravates lub tsis ua hauj lwm ntawm lub valve.Yog li ntawd, nyob rau hauv kev ua haujlwm hnyav xws li kev thauj mus los ntawm hmoov, hnav tsis kam yog qhov tseem ceeb ntawm kev ntsuas kev ntsuas ntawm lub valve.
Peb xaiv ib qho sintered tungsten carbide ua cov khoom sivua valve, uas tsis tsuas yog muaj lub zog siab, tab sis kuj muaj qhov ua tiav ntawm qhov chaw siab, thaum siv lwm cov ntaub ntawv, kev sib txhuam coefficient me dua li cov hlau, uas tuaj yeem txo qhov kev sib txhuam ntawm qhov chaw sib cuag thiab txo qhov kev ua haujlwm torque.
Integral sintered tungsten carbide yog tsim los ntawm cua sov sib tov ntawm tungsten thiab carbon ntawm qhov kub thiab txias, feem ntau ntawm cov tungsten carbide muaj siab hardness,yog li ntawd tsis yooj yim rau decompose ntawm qhov kub thiab txias, thiabkujmuaj oxidation zoo.
Nyob rau hauv lub thee gasification valve, lub valve disc thiab lub rooj zaum valve yog ua los ntawm ib tug sintered tungsten carbide los tsim ib tug sealing khub, thiab lub valve muaj cov nram qab no pom tseeb zoo.:
1,Siab hardness.hardness> 80HRC, uas tuaj yeem tiv taus qhov kub ceev yaig ntawm multiphase particle media xws li thee-dej slurry, pulverized thee, silica fume, thiab lwm yam.
2,Kub kub kuj.Nws tuaj yeem ua haujlwm ntawm750 ° C kub siab rau lub sijhawm ntev, thiab nws lub zog, adhesion thiab thermal expansion tsis txwv los ntawm qhov kub thiab txias, uas ua tau raws li qhov kub thiab txias xws li kev lag luam thee..
3,Kev kub siab tsis kam.Lub transverse tawg lub zog ntawm tag nrho sintered tungsten carbideua tauncav cuag 4000MPa, uas yog ntau tshaj 10 zaugof cov pa hlau.
4,Corrosion-resistance.Tag nrho cov sintered cemented carbide yog tshuaj ruaj khov, insoluble hauv dej txawm tias rhuab, thiab tsis cuam tshuam nrog hydrochloric acid thiab sulfuric acid.
5,Abrasion resistance.Cov yam ntxwv ntawm siab hardness thiab siab stability ntawm ib qho tseem ceeb sintered cemented carbide xyuas kom meej qhov zoo heev los tiv thaiv kev ua tau zoo ntawm sealing sub-khoom..
6,Erosion Resistance.
Feem ntau, cov sintered tungsten carbide cemented carbide muaj lub zog siab, siab hardness, siab melting point, siab stability, tsis tshua muaj coefficient ntawm kev sib txhuam, hnav tsis kam, yaig tsis kam thiab cavitation, corrosion kuj, thiab kev tsim ntawm hnav-resistant valve seals rau Kev ua haujlwm hnyav tuaj yeem txhim kho qhov kev siv ntawm lub valve, nthuav dav siv ntau yam ntawm lub valve, thiab ua kom lub neej ua haujlwm ntev ntawm lub valve.
Zhuzhou Chuangrui Cemented Carbide Co., Ltd. muab high-end hnav-resistant cov ntaub ntawv thiab kev valve nto hardening tshuab los muab kev daws teeb meem rau hnyav ua hauj lwm tej yam kev mob ntawm cov thee tshuaj lom neeg kev lag luam..
