I. Cov Ntsiab Cai rau Kev Xaiv Cov Tshuaj Tiv Thaiv rau V-Rings
Raws li ib qho tseem ceeb ntawm cov khoom sib khi, V-rings yuav tsum xav txog yam xws li kev ua haujlwm ib puag ncig, tshuaj lom neeg, thiab kev siv nyiaj txiag zoo thaum xaiv cov tshuaj lom neeg. Cov hauv qab no yog qee cov hauv paus ntsiab lus rau kev xaiv cov tshuaj lom neeg rau V-rings:
1. Kev ua haujlwm ib puag ncig kev sib txuam: Ua ntej, xyuas kom meej tias cov khoom siv tshuaj lom neeg uas tau xaiv tau sib haum rau qhov chaw ua haujlwm ntawm V-ring. Qhov no txhais tau hais tias V-ntiv nplhaib yuav tsum muaj peev xwm ua haujlwm tau zoo nyob rau hauv qhov xav tau ntawm qhov kub thiab txias, siab, thiab tshuaj lom neeg ib puag ncig, thiab yuav tsis degrade los yog poob vim yog kev sib cuag nrog tshuaj lom neeg.
2. Tshuaj tiv thaiv: Thib ob, xav txog cov tshuaj tiv thaiv ntawm V-ring. Cov ntaub ntawv V-ring sib txawv muaj qhov sib txawv rau cov tshuaj sib txawv. Piv txwv li, polytetrafluoroethylene (PTFE) V-rings muaj kev tiv thaiv corrosion zoo heev thiab tiv taus yuav luag txhua yam tshuaj lom neeg, thaum graphite V-rings yog tsim rau kev tshaj tawm xws li dej kub, kub kub thiab siab zog.
3. Nqi-zoo: Thaum kawg, xav txog tus nqi-zoo. Txawm hais tias cov ntaub ntawv V-ntiv nplhaib muaj kev ua haujlwm siab tuaj yeem muaj cov tshuaj tiv thaiv zoo dua, lawv kuj yuav raug nqi ntau dua. Yog li ntawd, thaum xaiv cov khoom siv tshuaj, nws yog ib qho tsim nyog yuav tsum sib npaug ntawm kev sib raug zoo ntawm kev ua tau zoo thiab tus nqi thiab xaiv cov khoom siv kom zoo tshaj plaws.
2. Cov khoom siv tshuaj lom neeg thiab lawv cov khoom siv V-ring
Cov hauv qab no yog ob peb yam tshuaj lom neeg thiab lawv cov khoom siv V-ring:
| Tshuaj lom neeg|Siv tau cov ntaub ntawv V-ring |
|------------------|--------------------|
| Cov roj|Fluororubber (FKM), Nitrile roj hmab (NBR) |
| Acid|Polytetrafluoroethylene (PTFE), graphite |
| Alkali|Polytetrafluoroethylene (PTFE), graphite |
| Solvent|Polytetrafluoroethylene (PTFE), Silicone roj hmab (VMQ) |
| Cov xov xwm kub kub|Graphite |
| Tsawg kub xov xwm|Polytetrafluoroethylene (PTFE) |
Thov nco ntsoov tias cov saum toj no tsuas yog cov lus qhia dav dav, thiab kev xaiv tshwj xeeb yuav tsum tau ua raws li qhov xwm txheej tiag tiag thiab cov khoom tshwj xeeb. Thaum xaiv cov ntaub ntawv V-ntiv nplhaib, nws yog qhov zoo tshaj plaws los sab laj nrog tus kws tshaj lij foob cov chaw tsim khoom lossis tus neeg muag khoom kom tau txais cov lus qhia tseeb tshaj plaws.
