Xaiv cov khoom siv Surfacing rau cov chaw valve

Cov khoom sib khi ntawm cov hlau li qub (DC341X-16 COJ FRANGED ECCENTRIC Npauj Npaim Valve) Feem ntau tsim los ntawm (Kaum ob valve) Surfacing vuam. Cov ntaub ntawv siv rau kev ua si valve tau muab faib ua 4 hom loj raws li cov hom alloys, Nickel-booly alloys, thiab tooj liab-raws li alloys. Cov ntaub ntawv alloy no tau ua rau hauv electrodes, vuam hlau (tungsten arcon arc moron vuam

Kev xaiv ntawm Valve Sealing Thaj Chaw Thaj Chaw (DC341X3-10Muab Ob Npaug Fulled Eccentric Npauj Npaim ValveLub cev lub nplhaib sib khi) feem ntau yog raws li qhov siv kub, ua haujlwm ntawm lub zog, lossis cov peev txheej ntawm cov khoom siv sib luag, lossis cov peev txheej ntawm cov neeg siv khoom thiab cov kev xav tau ntawm cov neeg siv. Cov qauv tsim qauv yuav tsum tau saws, thiab cov txheej txheem sib npaug thiab cov txheej txheem ntau lawm yuav tsum raug xaiv nyob rau hauv kev ua tiav ntawm (D341X3-16 Muab ob npaug rau concentric Npauj npaim Valve) valve valve.

Qee cov ntaub ntawv siv rau kev nthwv dej ntawm Valve muaj tsuas yog ib daim ntawv xwb, lossis hluav taws xob lossis vuam hlau lossis cov hmoov sib txuas, yog li tsuas yog ib txoj kev taug kev tuaj yeem siv tau. Ib txhia yog ua rau hauv vuam pas nrig, vuam cov xov hlau lossis cov roj av alloy (D801), ob lub vuam hlau vuam Vuam thiab lwm txoj hauv kev tuaj yeem siv rau cov vuam vuam vuam. Thaum xaiv cov ntaub ntawv Surfacing rau cov khoom sib luag valve, peb yuav tsum tau ua tiav kev xaiv ntawm kev lag luam, yooj yim thiab kev ua tau zoo ntawm kev tsim kho ntawm kev tsim cov khoom sib khi.

Cov saum npoo sib khi yog qhov tseem ceeb ntawm lub valve (D371X-10 Wafer Npauj Npaim Valve), thiab nws qhov zoo ncaj qha cuam tshuam rau lub neej kev pabcuam ntawm lub valve. Qhov kev xaiv tsim nyog xaiv ntawm cov khoom siv hluav taws xob yog ib qho ntawm cov hauv kev tseem ceeb los txhim kho kev pabcuam lub neej ntawm lub valve. Tsis to taub yuav tsum zam rau hauv kev xaiv ntawm valve cov khoom lag luam nto.

Myth 1: Lub hardness ntawm lub valve (D371x3-16c) Cov khoom lag luam saum npoo av yog qhov siab, thiab nws cov kev coj ua tau zoo yog qhov zoo.

Kev sim qhia pom tias cov hnav tsis kam ntawm cov khoom siv nto cuam tshuam saum npoo av yog txiav txim siab los ntawm microstructure ntawm cov khoom siv hlau. Qee cov ntaub ntawv hlau nrog Austenite raws li lub matrix thiab ib qho me me ntawm theem nyuaj ua qauv tsis nyuaj, tab sis lawv cov coj tsis kam yog qhov zoo heev. Kev sib khi saum npoo ntawm lub valve muaj qee yam nyuaj kom tsis txhob raug mob thiab kos los ntawm cov khib nyiab nyuaj hauv nruab nrab. Txhua yam suav tias, lub hardness nqi HRC35 ~ 45 yog qhov tsim nyog.

Cov lus qhia 2: Tus nqi ntawm Valve sealing cov khoom siv nto yog siab, thiab nws qhov kev ua tau zoo yog qhov zoo.

Tus nqi ntawm cov khoom yog nws tus kheej cov khoom lag luam tus yam ntxwv, thaum cov khoom lag luam ntawm cov khoom yog nws lub cev yam ntxwv, thiab tsis muaj kev sib raug zoo ntawm ob. Lub cobalt cov hlau hauv kev cobalt-based alloys los ntawm kev ntshuam, thiab tus nqi yog siab, yog li tus nqi ntawm cobalt-based alloy cov ntaub ntawv yog siab. Cobalt-raws li alloys muaj cim los ntawm cov kev coj zoo tiv thaiv ntawm cov kev kub siab, thaum siv cov xwm txheej thiab nruab nrab ntawm cov khoom siv. Nyob rau hauv kev xaiv ntawm valve cov ntaub ntawv nto moo, cov ntaub ntawv nrog tus nqi qis / kev ua tau zoo yuav tsum tau xaiv.

MYTH 3: Yog tias cov khoom siv sib khi ntawm lub pob hluav taws xob tau zoo corrosive tsis kam nyob rau hauv ib qho muaj zog corrosive nruab nrab, nws yuav tsum hloov mus rau lwm cov xov xwm corrosive.

Cov khoom lag luam tsis kam ntawm cov ntaub ntawv hlau muaj nws tus kheej complex kevism, thiab cov khoom siv me me, xws li qhov nruab nrab lossis nruab nrab ntawm kev ua haujlwm tau hloov. Rau lwm qhov nruab nrab ntawm nruab nrab, cov xeb tawm tsam ntau dua. Cov corrosion tsis kam ntawm cov ntaub ntawv hlau tsuas yog tuaj yeem paub los ntawm kev sim, thiab cov mob uas cuam tshuam yuav tsum tau nkag siab los ntawm cov ntaub ntawv tsim nyog, thiab yuav tsum tsis txhob dig muag.
