1. Cov neeg hauv tsev neeg thiab thaj chaw nyob (xws li coj mus rhaub dej thiab roj li qub)
Media: ntxuav cov kais dej, cov nkev roj (tsis - corrosive)
Kev Ua Haujlwm Kev Ua Haujlwm: Tsis tshua muaj siab (qis dua lossis sib npaug rau 1 MPa), Chav Chav (-10 Qib rau 60 degree)
Khoom siv: Tooj liab, cam khwb cia hlau, yas (PPR, PVC)
LIFPANK: 10-20 xyoo
Tooj liab li qub (xws li tooj dag pob li qub) yog cov corrosion heev - tiv taus thiab tuaj yeem ntev tshaj 20 xyoo nrog kev tu xyuas kom zoo.
Nrum hlau li qub yog nquag mus rau xeb. Yog tias cov dej ua tau zoo tsis zoo (muaj cov khoom ntsiag to thiab impurities), lawv yuav dhau los ua daig lossis nqhis dej tom qab 10 xyoo.
Yas li qub yog cuam tshuam los ntawm qhov kub. Ntev ntev los ua lub hnub ci ncaj qha lossis kub siab yuav ua rau lawv lub neej ua haujlwm ntev li 5-10 xyoo.
2. Muaj Dav Ua Haujlwm Ua Haujlwm Li Qub (xws li dej, chav, roj tshuab)
Nruab Nrab: Cov dej huv, cheourated chav, ntxhia roj (qis corrosive)
Kev Ua Haujlwm Pabcuam: Nruab Nrab Nruab Nrab (1 ~ 10MPA), Nruab Nrab Nruab Nrab (Tsawg dua lossis sib npaug rau 200)
Khoom siv: cam khwb cia hlau (WCB), stainless hlau (304), zas hlau
LIFPANGAN: 8 ~ 15 xyoos
Ntsia (xws li roj hmab, polytetrosraethoroethylene) yog hnav ib feem. Yog tias hloov tsis tu ncua, lub cev valve tuaj yeem txuas ntxiv mus rau ntau tshaj 15 xyoos;
Chav li qub yog nquag hnav vim muaj kev nquag siv ntawm kub thiab txias, thiab cov ciaj sia tau yooj yim, thiab lub neej yuav luv luv txog 5 ~ 8 xyoo.
3. Corrosive / Harts Ua Haujlwm Pab Cuam Tshuam (xws li acid, alkali, thiab nruab nrab muaj cov lus)
Nruab nrab: acid thiab alkali daws, dej hiav txwv, av nkos, cov zeb lim
Kev Ua Haujlwm Pabcuam: Nruab Nrab thiab Tsawg Tshaj Plaws (Tsawg dua lossis sib npaug), kub (200 ~) lossis qis dua lossis sib npaug.
Cov Khoom Siv: Corrosion - istant stainless hlau (316), hastelline, fluorine- txoj kab (PTFE)
LIFPANK: 3 ~ 10 xyoo
Yog hais tias nruab nrab yog corrosive heev (xws li hydrochloric acid, corrosion {{}} Cov khoom siv sib tsoo, thiab lub neej pabcuam tsuas yog 3 ~ 5 xyoos;
Nruab nrab muaj cov khoom (xws li slurry, dej phwj tuaj) yuav yauv lub rooj zaum valve thiab cov kev pabcuam valve, thiab lub neej pabcuam feem ntau yog 3 ~ 8 xyoo.
4. Li qub rau high - qhov siab, siab} Cov nroj tsuag muaj zog, high {}|{}} siab} siab} Siab} Siab}} {} |
Media: High - h siab strea, siab {}} {-} roj av
Kev Ua Haujlwm Kev Ua Haujlwm: Kev Kub Siab Tshaj (Ntau dua lossis sib npaug rau 10 MPA), kub tshaj lossis sib npaug nrog 400 degree)
Cov Khoom Siv: Alloy Txheej txheem hlau (piv txwv li, cr - mo hlau), forged stainless hlau
Lifespan: 5-10 xyoo
Txom nyem los ntawm ntev -}}} txoj kev ntxhov siab, thiab cov rooj zaum hauv qab, thiab cov rooj zaum tsis tu ncua (piv txwv li, kev kuaj ultrasonic). Lifespan feem ntau tsis pub tshaj 10 xyoo.
TSEEM CEEB TSEEB TSEEB:
Kev Txij Nkawm: Lub sijhawm siv lubrication, ntxuav, thiab hloov pauv ntawm lub neej, ntim) tuaj yeem txuas valve lub neej los ntawm 30% -50%.
Kev ua haujlwm ntawm kev ua haujlwm: Li qub uas nquag qhib thiab kaw (piv txwv li lub sijhawm uas muaj tsawg kawg yog 50% luv dua li qub (ob peb zaug hauv ib hlis).
