Dab tsi yog qhov nruab nrab lifespan ntawm platinum tsis kam ntsuas kub (PTF) nyob rau hauv ib puag ncig corrosive heev
Tso lus
Nyob rau hauv ib puag ncig corrosive heev, qhov nruab nrab ntawm lub neej ntawm PTF feem ntau yog 2 mus rau 5 xyoo, nyob ntawm qhov txaus ntawm kev tiv thaiv. Yog tias tsis muaj kev tiv thaiv corrosion zoo, lub neej ntev yuav raug txo kom tsawg dua 1 xyoos. Txawm li cas los xij, nrog ob npaug - lub tes tsho qauv, ib qho sintered polytetrafluoroethylene (PTFE) los tiv thaiv - txheej corrosion, thiab siab - zoo sealing tov, lub neej yuav ntev mus rau ntau tshaj 5 xyoo. Nyob rau hauv ib puag ncig uas muaj siab - nrawm nrawm, qhov hnav{11}} txheej tiv thaiv tuaj yeem txuas ntxiv lub neej ntawm cov txheej txheem tiv thaiv -corrosion los ntawm 8-10 zaug.
I. Tej yam tseem ceeb cuam tshuam rau lub neej ua haujlwm

Kev piav qhia |
|
Hom Media |
Cov chaw muaj corrosive heev uas muaj chloride ions, H₂S, los yog cov kua qaub muaj zog (xws li hydrochloric acid thiab sulfuric acid), yooj yim ua rau pitting thiab perforation. |
|
Flow Rate thiab Erosion |
Siab- ntws- tus nqi xov xwm nrawm hnav, ua rau tsis ua haujlwm sai ntawm cov raj tiv thaiv lossis tiv thaiv- txheej txheej. |
|
Qhov kub thiab txias |
Ntev -lub sij hawm raug kub siab tshaj 300℃accelerates cov khoom aging thiab oxidation. |
|
Vibration thiab Thermal Cycling |
Feem ntau pib-ups thiab shutdowns ua rau thermal stress fatigue, cuam tshuam rau qhov chaw vuam thiab lead hlau txuas. |
Cov ntaub ntawv tseem ceeb: Tsis muaj kev tiv thaiv 304 stainless hlau tiv thaiv cov raj tso tawm pitting thiab perforation hauv 6 lub hlis hauv Cl⁻- muaj ib puag ncig; thaum lub platinum tiv thaiv tus pas ntsuas kub siv 904L + PTFE ib leeg sintered qauv tuaj yeem ua haujlwm ruaj khov rau ntau tshaj 4 xyoo nyob rau hauv tib lub sijhawm.

Extreme Corrosion Conditions |
Technical Basis: Lub anti-corrosion platinum tiv thaiv tus pas ntsuas kub yuav tsum dhau 12kV spark micro- qhov tsis pom kev kom paub tseeb tias cov txheej tiv thaiv-corrosion tsis muaj qhov tsis xws li pinhole, txhim kho kev ntseeg tau tag nrho.
III. Cov tswv yim tseem ceeb rau Extending Service Life
Cov khoom siv kho dua tshiab: Ua ntej corrosion- cov alloys tiv taus xws li 904L thiab Hastelloy ua cov khoom siv tiv thaiv tubing.
Kev ua kom zoo ntawm cov qauv: Siv ob lub- tes tsho tsim kom tsis txhob muaj kev ntxhov siab thermal, ua ke nrog lub flange txav tau los them nyiaj rau kev hloov pauv thermal.
Los tiv thaiv - Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheem: Siv cov txheej txheem sintered PTFE los tiv thaiv kev sib koom ua ke thiab txhim kho corrosion kuj zoo.
Sealing Enhancement: Cov thawv ntim khoom siv fluororubber (FKM) sealing rings, ua tiav IP65 lossis siab dua kev tiv thaiv ntsuas los tiv thaiv kev ya raws.
Installation Standards: Khaws ib tug ntau dua los yog sib npaug rau 5 hli clearance rau txav; nteg tawm ntau dua los yog sib npaug rau 200mm S-zoo li tus redundant arcs rau cov hlau lead kom tshem tawm cov kev ntxhov siab.
Kev Saib Xyuas Tsis tu ncua: Kev ntsuas rwb thaiv tsev tiv thaiv txhua 6 lub hlis (Ntau dua lossis sib npaug ntawm 100MΩ tau txais); tsim cov ntaub ntawv sib txawv rau kev kwv yees txij nkawm.
Kev pom zoo kev lag luam: 75% ntawm qhov ua tsis tiav thaum ntxov yog los ntawm kev teeb tsa tsis raug lossis tsis muaj kev saib xyuas; Kev xaiv kev tshawb fawb thiab kev ua haujlwm tau zoo tuaj yeem txuas ntxiv lub neej kev pab cuam kom nyob ze rau qhov tsim txwv.
