Hauv cov nplhaib sib khi ntawm kev sib sib zog nqus groove pob bearings, corrosion tsis zoo ntawm cov roj hmab khoom (ua los ntawm cov khoom siv roj hmab) thiab cov khoom siv hlau) thiab cov khoom siv siv tau. Ntawm no yog cov ncauj lus kom ntxaws:
1. Roj hmab Cap (roj hmab sealing nplhaib)
Cov yam ntxwv cov khoom siv: Cov khoom siv sib xyaw ua ke suav nrog roj hmab nitrile (NBR), roj hmab fluorine roj hmab (FKQ), thiab lwm yam.
Cov txiaj ntsig zoo: Kev hloov pauv tau zoo, tsim muaj zog sealial kev ua tau zoo, tsim nyog rau cov chaw muaj zog tsis muaj zog (xws li hauv cov chaw muaj kev lag luam tsis muaj zog).
Corrosion tsis kam rau txhua cov khoom siv:
NBR: Zoo heev roj ua tsis tau zoo, tab sis kuj tsis muaj zog nyob rau hauv cov nqe lus ntawm kev tiv thaiv kom muaj zog acids / alkalis lossis oxidants.
FKM: Tiv thaiv kom kub thiab tshuaj lom neeg (suav nrog cov roj ntsha (suav nrog cov roj, acids, thiab cov kuab tshuaj), haum rau ib puag ncig.
VMQ: Tiv thaiv kom muaj kub thiab ozone, tab sis tsawg tsis kam mus rau hydrocarbon cov kuab tshuaj.
2. Hlau Cap (Hlau Sealing Ntiv Nplhaib)
Cov yam ntxwv cov khoom siv: feem ntau ua los ntawm cov hlau, thiab tej zaum yuav coated (xws li galvanized lossis chrome - plated) lossis ua los ntawm stainless hlau.
Cov txiaj ntsig zoo: Muaj lub zog txhua yam thiab hnav tsis kam, haum rau high {{} {}} qhov siab}} qhov siab xav tau cov qauv txheej txheem txheej txheem qauv txheej txheem. Txawm li cas los xij, corrosion tsis kam yuav tsum tau txhim kho los ntawm kev kho deg.
Corrosion tsis kam rau txhua cov khoom siv:
Zoo tib yam hlau: tsis muaj kev hloov pauv, nws yog nquag mus xeb thiab muaj kev tsis zoo corrosion tsis kam.
Coated steel: cov txheej tuaj yeem ncua kev xeb, tab sis thaum muaj piam, cov khoom siv hauv paus tseem pheej yuav xeb.
Stainless hlau: muaj kev tiv thaiv corrosion (tshwj xeeb yog 316 stainless hlau), tab sis nrog tus nqi siab dua.
3. Sib piv Qhov xaus
Pa Ib puag ncig:
Cov roj hmab caps (tshwj xeeb tshaj yog FKM lossis NBR) ua tau zoo dua hauv cov chaw muaj zog thiab qaug zog thiab tsis muaj zog ntawm lawv cov khoom lag luam thiab cov khoom tsis kam.
Yog tias cov hlau npog yog ua los ntawm cov hlau zoo tib yam thiab tsis tau kho, nws corrosion kuj yog tus tsis zoo; Yog tias nws yog ua los ntawm cov hlau uas tsis muaj hlau lossis muaj txheej txheej, nws yuav zoo dua rau roj hmab zoo tib si.
Tshuaj lom neeg ib puag ncig:
Muaj zog acids / alkalis lossis cov kuab tshuaj yuav corrode roj hmab (tshwj tsis yog rau FKM). Hauv cov xwm txheej zoo li no, cov khoom yuav tsum tau xaiv raws li cov nruab nrab tshwj xeeb.
Stainless hlau npog yog ntau txhim khu kev qha nyob rau hauv ib puag ncig corrosive heev, tab sis nws yog ib qho tsim nyog los xyuas kom meej (xws li 316L stainless hlau).
4. Cov lus thov tswv yim
Xav tau cov roj hmab kaus mom: yog tias ib puag ncig yog vaum lossis muaj cov xov xwm muaj kev lag luam zoo, xaiv cov roj hmab roj hmab thiab nitrile roj hmab kaus mom.
Xaiv cov hlau npog: yog lub zog siab, muaj zog - qhov kub tsis kam, thiab yog lub nplhaib hlau khi tuaj yeem raug txiav txim siab.
Ntsiab lus: Tsis paub txog cov khoom siv tseeb ntawm "Hlau Npog", peb xav tias nws yuav yog hlau dog dig. Hauv qhov no, cov roj hmab npog (tshwj xeeb tshaj yog siab siab- kev ua tau roj hmab) feem ntau yog cov tiv taus corrosion. Yog tias cov hlau npog yog ua los ntawm cov hlau uas tsis muaj hlau lossis lub siab- Cov roj hmab zoo me me, nws yuav zoo dua rau cov roj hmab zoo tib yam. Qhov kev xaiv tiag tiag yuav tsum tau ua raws cov kev ua haujlwm thiab cov ntaub ntawv tshwj xeeb.
