Txawv teb chaws lub cev puncture to tsis ua hauj lwm hais txog cov impurities nyuaj xws li hlau scraps, vuam slag, gravel thiab tawg valve qhov chaw sib tov rau hauv nruab nrab conveying. Cov khoom siv khov kho no ntws nrog cov kua dej hauv cov raj xa dej thiab ua rau muaj kev cuam tshuam rau sab hauv PFA hauv ob sab phlu. Cov npoo ntse txiav los ntawm cov fluoroplastic tiv thaiv- txheej txheej corrosion los tsim cov pinpoint qhov nkag los yog tsis tu ncua tearing qhov khoob. Corrosive nruab nrab nkag mus rau hauv cov kab puas tsuaj los ua rau cov yeeb nkab steel, thiab cov xaim me me maj mam nthuav dav nyob rau hauv ntev - lub sij hawm nruab nrab scouring, thaum kawg ua rau pom tseeb pipeline to thiab substrate xeb perforation. Qhov kev ua tsis tiav no yog los ntawm ib qho - lub sij hawm mechanical penetration puas tsuaj, uas feem ntau tshwm sim nyob rau hauv tshiab muab tso rau hauv - mus rau hauv - cov kav dej thiab cov txheej txheem txheej txheem nrog kev tu cov kav dej tsis tiav.
1. Txawv Teb Chaws Khoom Impact thiab Puncture Damage Mechanism
PFA hauv ob sab phlu muaj tshuaj tiv thaiv zoo tab sis tsis zoo los tiv thaiv- txiav muaj peev xwm tiv thaiv cov khoom tawv tawv. Thaum cov khoom txawv teb chaws tsis nruj yog nqa los ntawm siab - cov kua dej nrawm, qhov cuam tshuam loj heev tshwm sim thaum sib tsoo nrog cov yeeb nkab phab ntsa hauv ob sab phlu. Lub kaum ntse ntse ntawm impurities ncaj qha txiav cov txheej fluoroplastic nyias los ntawm qhov, rhuav tshem cov khoom tiv thaiv kev tiv thaiv -corrosion barrier. Tom qab lub hauv ob sab phlu yog punctured, qhov nruab nrab ncaj qha hu rau carbon steel puag yeeb nkab, ua rau lub zos rusting thiab corrosion. Thawj qhov me me yog txuas ntxiv ntxuav thiab nthuav dav los ntawm qhov nruab nrab ntws, ua rau hauv ob sab ntug curling thiab lub qhov loj. Tsis zoo li kev puas tsuaj los ntawm qhov ntev - lub sij hawm particle yaig, qhov tsis ua hauj lwm no yog qhov kev puas tsuaj ntawm cov pob zeb loj loj ntawm ib tus neeg tsis yog cov khoom hnyav hnyav.
2. Cov hauj lwm zoo tshaj plaws rau cov khoom txawv teb chaws puncture
Lub luj tshib sab hauv arc qhov chaw uas cov kua hloov cov kev taw qhia thiab cov khoom txawv teb chaws mloog zoo;
Tee ceg kev sib tshuam nrog turbulent flow thiab muaj feem ntau ntawm cov khib nyiab sib tsoo;
Reducer yeeb nkab ntu nrog nrawm nrawm nrawm thiab txhim kho qhov cuam tshuam kinetic zog ntawm impurities;
Cov kav xa dej hauv qab ntawm cov twj tso kua mis uas cov kua dej siab thiab qhov nrawm nrawm yog siab tshaj;
Qhov muag tsis pom cov kav dej thiab qhov kawg tuag qhov twg cov khoom siv tau raug daig thiab rov ua dua lub hauv ob sab phlu.
3. Core Inducing Factors Accelerating Puncture Failure
Tsis tiav cov kav dej yaug thiab ntxuav tom qab kev tsim kho, tawm hauv vuam slag, txiav chips thiab cov khoom siv pov tseg hauv cov yeeb nkab;
Cov khoom siv kho dua tshiab thiab hloov cov khoom siv qhia cov khoom tawg tawg thiab cov hlau shavings rau hauv lub cev;
Tsis muaj lim thiab cov thoob khib nyiab ntsia ntawm lub raj xa dej kom cuam tshuam cov khoom txawv teb chaws hauv cov khoom noj nruab nrab;
Ntau qhov nruab nrab ntws tus nqi nce qhov cuam tshuam ntawm cov khoom siv thiab nce qhov tshwm sim;
Hauv ob sab phlu thickness tsis txaus uas tsis muaj kev tiv thaiv ntxiv ntawm kev cuam tshuam - cov yeeb nkab fittings.
4. Tag nrho -Txuas Kev Tiv Thaiv thiab Tswj Kev Ntsuas Kev Ntsuas
① Ua kom nruj ntau- dhau siab - cov dej ntws ntws tawm ua ntej qhov system commissioning
Tshem tawm cov khoom seem hauv cov kav dej kom huv si.
② Nruab ntau- theem lim thiab cov khoom siv av tas mus li ntawm qhov kawg ntawm cov kav dej
Thaiv lub cev txawv teb chaws nyuaj los ntawm kev nkag mus rau hauv cov kav dej los ntawm qhov chaw.
③ Tswj cov txheej txheem kev hloov pauv thiab kev saib xyuas kev ua haujlwm tshwj xeeb
Tiv thaiv kom tsis txhob ntim cov khoom tawg thiab cov khoom hlau los ntawm kev poob rau hauv cov txheej txheem kav dej.
④ Tsim nyog ua kom cov hauv ob sab phlu thickness ntawm lub luj tshib, tees thiab lwm yam yooj yim yeeb nkab fittings
Txhim kho lub peev xwm los tiv thaiv cov khoom ntse txiav thiab cuam tshuam.
⑤ Ua qhov kev tshuaj ntsuam xyuas endoscopic rau cov kav dej tshiab ua haujlwm hauv thawj lub hlis ntawm kev pib
Nrhiav thiab kho qhov tsis xws luag ntawm qhov pib ntawm kev puas tsuaj.

Xaus
PFA hauv ob sab phlu txawv teb chaws lub cev tsis ua hauj lwm yog tshwm sim los ntawm cov impurities nyuaj sib xyaw hauv nruab nrab cuam tshuam thiab txiav cov txheej txheem tiv thaiv -corrosion los tsim cov qhov nkag, uas ua rau cov substrate corrosion thiab nruab nrab to. Cov txheej txheem kev tiv thaiv tseem ceeb suav nrog kev ua tiav ua ntej- kev ua haujlwm tu kav dej, teeb tsa pem hauv ntej- kawg cov chaw lim dej txhawm rau cuam tshuam cov khib nyiab, kev tswj xyuas cov txheej txheem los tiv thaiv kev qhia txog kev tsis huv hauv nruab nrab, ntxiv dag zog rau cov txheej txheem tuab ntawm qhov cuam tshuam yooj yim thiab ua tiav kev tshuaj xyuas sab hauv thaum ntxov. Tag nrho - txheej txheem tswj kev lees txais qhov project, kev tswj hwm kev ua haujlwm thiab kev saib xyuas cov cuab yeej siv niaj hnub tuaj yeem tshem tawm qhov ua txhaum ntawm PFA kab cua sov cov raj uas raug cuam tshuam los ntawm cov khoom siv txawv teb chaws.
