Spare Heater Txee
Taug kev los ntawm txhua lub khw muag khoom noj khoom haus plating thiab pom qhov pom tau tshwm sim: rhawv tuav cov khoom siv hluav taws xob tso rau hauv qhov chaw sov-stainless steel, titanium, quartz-tseem nyob rau hauv lawv cov ntim qub, yuav tawm tsam hnub thaum lub tshuab ua haujlwm tsis ua haujlwm. Rau ib lub khw nrog 20 lub tso tsheb hlau luam, cov khoom seem seem feem ntau suav nrog 4-6 lub tshuab cua sov uas sawv cev rau $ 15,000- $ 30,000 hauv cov peev txheej.
Cov khoom muag no yog qhov tsim nyog vim tias cov cua sov hlau ua tsis tau zoo. Thaum ib lub kauj tsim lub pinhole rau hnub Tuesday tav su, yuav tsum muaj kev hloov tam sim ntawd. Tos 2-3 lub lis piam rau kev hloov pauv los tsim thiab xa tawm txhais tau tias 2-3 lub lis piam ntawm kev tsim khoom ploj. Cov khoom muag khoom seem yog kev pov hwm tiv thaiv qhov kev poob lawm.
PTFE heat exchangers hloov qhov kev tuav pov hwm vaj huam sib luag. Lawv hom tsis ua hauj lwm tsis yog cia li pinhole to tab sis maj mam phab ntsa thinning ntes tau xyoo ua ntej los ntawm kev ntsuas ultrasonic. Cov khoom siv thaum muaj xwm txheej ceev- lub tshuab cua sov ntawm lub txee tos rau qhov kev npaj txhij txog ib tag hmo ua tsis tiav- yuav tsis tsim nyog. Cov peev uas khi rau hauv cov khoom muag tau raug tso tawm rov qab rau kev lag luam.
Cov Khoom Muag Khoom Siv Tus Nqi Them Nqi
Tus nqi nqa khoom yog tag nrho tus nqi ntawm kev tuav cov khoom hauv Tshuag rau ib xyoos. Nws suav nrog: tus nqi peev (cov nyiaj uas tau muab khi rau hauv cov khoom tuaj yeem tau txais txiaj ntsig lossis nyiaj txiag lwm yam haujlwm), qhov chaw cia khoom (qis, nqi hluav taws xob, kev saib xyuas chav tsev), kev tuav pov hwm, kev pheej hmoo tsis zoo, thiab kev tuav haujlwm.
Rau kev lag luam khoom seem, feem ntau siv txhua xyoo nqa tus nqi yog 15-25% ntawm cov khoom tus nqi. Rau cov hlau immersion rhaub, muaj ib qho kev pheej hmoo ntxiv: cia corrosion. Lub tshuab cua sov stainless hlau khaws cia rau ob xyoos nyob rau hauv qhov chaw ntub dej ntawm lub khw plating tuaj yeem txhim kho qhov corrosion uas cuam tshuam nws txoj kev ncaj ncees ua ntej nws puas tau teeb tsa. Qhov kev khaws cia degradation no ntxiv rau tus nqi nqa tau zoo.
PTFE cov cua sov tsis muaj qhov pheej hmoo cia degradation. Cov khoom tsis corrode nyob rau hauv atmospheric cia. Lub PTFE rhaub khaws cia rau ib xyoo caum yog zoo ib yam rau ib qho uas tsim nag hmo. Yog tias ib qho khoom seem khaws cia, nws khaws nws cov nqi tas li tsis tu ncua-tab sis cov ntaub ntawv khaws cia txawm tias ib qho khoom seem tsis muaj zog thaum qhov ua tsis tiav tuaj yeem kwv yees thiab npaj xyoo ua ntej.
Table 1: Ua hauj lwm peev cuam tshuam ntawm Spare Inventory Reduction (20-Tank Plating Facility)
| Khoom Parameter | Nrog Metallic Heaters | Nrog PTFE Kub Exchangers |
|---|---|---|
| Tus naj npawb ntawm cov khoom siv hluav taws xob seem | 5 (sib tov ntawm SS, Ti, quartz) | 0-1 (yeem; tsis tas yuav tsum tau) |
| Tus nqi nruab nrab ntawm ib lub tshuab cua sov | $4,500 | $9,500 |
| Tag nrho cov khoom seem seem | $22,500 | $0-$9,500 |
| Tus nqi nqa txhua xyoo ntawm 20% | $4,500 | $0-$1,900 |
| Cia qhov chaw nyob (m²) | 2-3 | 0-0.5 |
| Cia degradation txaus ntshai | Nruab nrab (corrosion nyob rau hauv ib puag ncig humid) | Tsis muaj |
| Kev hloov pauv thaum muaj xwm txheej ceev tsis muaj qhov seem | 2-3 lub lis piam | N/A (kev ua tsis tiav yog kwv yees) |
| Kev pheej hmoo ntau lawm ntawm xoom- lub tswv yim tshwj xeeb | Siab (tsis tuaj yeem twv tsis tau) | Tsawg heev (predictable; npaj hloov pauv) |
| Ua hauj lwm peev tso tawm | – | $13,000-$22,500 |
Qhov Predictability Premium
Qhov sib txawv tseem ceeb ua rau kev tshem tawm cov khoom seem tsis yog tias PTFE exchangers yeej tsis ua tsis tiav - lawv thiaj li ua tau, los ntawm kev nkag mus tau ntau xyoo. Qhov txawv yog tias PTFE tsis ua haujlwm yog kwv yees tau. Ultrasonic thickness ntsuas txhua xyoo taug qab cov seem phab ntsa tuab. Tus nqi ntawm thinning yog paub los ntawm kev khiav hauj lwm kub thiab siab. Hnub hloov pauv tuaj yeem kwv yees nrog qhov tsim nyog raug xyoo ua ntej.
Kev hloov pauv PTFE tuaj yeem raug txiav txim 6-8 lub lis piam ua ntej hnub hloov pauv, tau teeb tsa thaum lub sijhawm saib xyuas lub qhov rais, thiab tus qub exchanger so ua ntej nws xau. Tsis tas yuav tsum muaj qhov xwm txheej ceev vim tsis muaj xwm txheej ceev.
Qhov no yog qhov sib txawv ntawm cov hlau sib txawv tsis ua haujlwm, qhov twg pitting corrosion tuaj yeem nkag mus rau qhov seem 10% ntawm phab ntsa tuab hauv hnub lossis lub lis piam, tsis muaj kev ceeb toom los ntawm kev tshuaj xyuas sab nraud. Cov khoom siv hlau yuav tsum nyob rau ntawm - qhov chaw vim tias qhov ua tsis tiav yog qhov tsis tuaj yeem xav tau thiab ceev ceev.
Cov Nyiaj Tau Los thiab Ua Haujlwm Peev Nyiaj Metrics
Cov peev nyiaj ua haujlwm yog cov cuab tam tam sim no rho tawm liabilities tam sim no. Cov khoom muag khoom muag yog ib qho cuab tam tam sim no. Txo cov khoom muag los ntawm $ 15,000-$ 25,000 ncaj qha txhim kho cov peev txheej ua haujlwm los ntawm qhov nyiaj ntawd. Cov nyiaj tso tawm tuaj yeem siv los them nyiaj rau kev hloov pauv PTFE nws tus kheej-, qhov txo qis hauv cov khoom muag khoom ib nrab ntawm tus kheej-nyiaj pab txhim kho.
Rau kev lag luam nrog 10% tus nqi peev, txo cov khoom muag tas li los ntawm $ 20,000 txuag $ 2,000 txhua xyoo hauv cov nqi nyiaj txiag ib leeg, nyob rau hauv perpetuity. Qhov no yog ntxiv rau kev zam cov nqi ntawm kev yuav khoom hloov cov khoom siv hluav taws xob thiab cov khoom siv kom tsis txhob muaj sijhawm poob.
Cov ntsiab lus
Hloov mus rau PTFE heat exchangers enables tshem tawm cov khoom thaum muaj xwm ceev spare qhov cub los ntawm transforming unpredictable, ceev hlau cua sov ua tsis tau tejyam rau kwv yees, npaj PTFE nyiaj laus. Cov peev nyiaj ua haujlwm tau tso tawm- feem ntau yog $ 13,000-$ 22,500 rau ib nrab ntawm - qhov chaw plating loj- txhim kho cov nyiaj ntsuab ntws thiab tuaj yeem ua ib feem ntawm nws tus kheej cov peev txheej PTFE.
Cov nyiaj khaws cia tsis tu ncua los ntawm kev tshem tawm cov khoom nqa nqa, suav nrog kev tshem tawm ntawm kev khaws cia- cuam tshuam txog kev degradation ntawm cov khoom siv hlau, ntxiv kwv yees li $ 2,500- $ 4,500 ib xyoos ib zaug hauv cov txiaj ntsig nyiaj txiag saum toj no thiab tshaj li kev khaws nyiaj ncaj qha.
Kev txhawb nqa engineering rau PTFE hloov dua siab tshiab ua haujlwm peev kev txheeb xyuas muaj nyob rau ntawm kev xa cov khoom seem tam sim no, cov khoom siv hluav taws xob tsis ua haujlwm, thiab cov nqi ntawm cov peev txheej.
