Stainless hlau Cartridge rhaub

Stainless hlau cartridge rhaub yog ib qho yooj yim tubular hluav taws xob cua sov qhov chaw uas muaj ib tug muaj zog stainless hlau sheath nyob ib ncig ntawm lawv. Cov cuab yeej ua haujlwm los ntawm cov cua sov tiv thaiv (Joule cua sov), uas hloov hluav taws xob rau hauv thermal zog thaum tam sim no mus los ntawm cov hlau coiled. Lub MgO tom qab ntawd hloov cov cua sov no, uas yog sib npaug sib npaug mus rau hauv daim ntawv thov lub hom phiaj los ntawm stainless hlau sheath. Qhov MgO no ua ob yam tseem ceeb: nws ua kom tsis muaj hluav taws xob ntws thiab nws cia cua sov ntws. Cov cuab yeej ua haujlwm los ntawm cov cua sov tiv thaiv (Joule cua sov), uas hloov hluav taws xob rau hauv thermal zog thaum tam sim no mus los ntawm cov hlau coiled. Lub MgO tom qab ntawd hloov cov cua sov no, thiab cov hlau tsis muaj steel hlau sib npaug sib npaug nws mus rau hauv daim ntawv thov. Lawv tau siv ntau hauv kev lag luam rau cua sov cov kua, cua, thiab roj, tswj pwm qhov kub thiab txias, kom qhuav qhov cub, ntim tshuab, thiab ntau ntau cov txheej txheem cua sov siv vim lawv muaj zog, zoo, thiab yoog raws.

Cov khoom siv thiab kev tsim cov tub ntxhais


Cov ntaub ntawv sheath yog ib qho tseem ceeb heev vim nws cuam tshuam ntev npaum li cas lub rhaub yuav kav ntev npaum li cas thiab nws tuaj yeem siv tau li cas. Qee cov qhab nia sib xws yog:

AISI 304 Stainless Steel yog tus qauv kev lag luam vim tias nws muaj peev xwm tiv taus corrosion feem ntau, tuaj yeem ua rau ntau qhov sib txawv, thiab pheej yig rau kev siv feem ntau uas suav nrog dej, lubricants, thiab tsis yog - corrosive ib puag ncig.

AISI 321 Stainless hlau zoo li 304 tab sis muaj titanium ntxiv rau nws kom nws tiv taus ntau dua rau kev sib txhuam thiab zoo dua rau ntev - siv rau qhov kub siab (feem ntau tshaj 400℃).

AISI 316 / L Stainless Hlau: Qib no tshwj xeeb tshaj yog tiv taus pitting thiab crevice corrosion, tshwj xeeb tshaj yog nyob rau hauv tsis muaj zog acid lossis chloride tej yam kev mob, ua tsaug rau muaj molybdenum. Rau ntau yam tshuaj thiab marine siv, nws yog cov khoom siv zoo tshaj plaws.

AISI 310S Stainless hlau yog austenitic alloy uas muaj ntau ntawm chromium thiab npib tsib xee. Nws tuaj yeem tswj tau qhov kub thiab txias (txog 1150 degree) thiab tiv taus oxidation thiab carburization, uas ua rau nws zoo meej rau siv rau hauv qhov cub.

Cov hlau cua sov sab hauv feem ntau yog ua los ntawm hlau -chromium- txhuas (FeCrAl) lossis npib tsib xee-chromium (NiCr) alloy. Hom hlau yog xaiv nyob ntawm qhov xav tau ua haujlwm kub, tsis kam tiv thaiv, thiab tus nqi. Lub siab -purity, electrofused magnesium oxide muab tub lim yog ua tib zoo ua kom tau qhov zoo tshaj plaws dielectric zog thiab thermal conductivity.

Tseem ceeb technical specs thiab kev ua tau zoo

Txhawm rau ua qhov kev xaiv zoo thiab khaws cov khoom kom nyab xeeb, koj yuav tsum paub cov kev txwv no.

Rated Voltage thiab Fais Fab: Cov qauv voltages yog 120V, 240V, 380V, thiab 480V. Txhawm rau kom tsis txhob muaj lub tshuab ua kom sov sai sai, qhov ntsuas hluav taws xob (wattage) yuav tsum tau ua tib zoo sib xyaw rau lub rhaub dej ntawm qhov chaw thiab daim ntawv thov lub peev xwm tshem tawm cov cua sov.

Qhov tseem ceeb tshaj plaws tsim qauv yog qhov chaw load (watt ntom), uas yog ntsuas nyob rau hauv watts ib square inch (W / in²) los yog watts ib square centimeter (W / cm²). Feem ntau, stainless hlau cartridge rhaub ua rau ntawm 5 thiab 15 W / cm² (30 thiab 100 W / in²). Thaum koj muab qhov hnyav ntau dhau rau ib yam dab tsi, lub tsho tau kub dhau thiab cov khoom tsis kav ntev li ntev.

Rated Voltage thiab Fais Fab: Cov qauv voltages yog 120V, 240V, 380V, thiab 480V. Txhawm rau kom tsis txhob muaj lub tshuab ua kom sov sai sai, nws lub zog ntsuas (wattage) yuav tsum yog tus nqi tsim nyog rau nws qhov chaw saum npoo av thiab qhov muaj peev xwm ua kom sov ntawm daim ntawv thov.

Qhov tseem ceeb tshaj plaws tsim qauv yog nto load (watt ntom). Nws yog ntsuas hauv watts ib square inch (W / in²) lossis watts ib square centimeter. Feem ntau cov qauv stainless hlau cartridge rhaub tso tawm ntawm 5 txog 15 W / cm² (30 thiab 100 W / in²) ntawm hluav taws xob. Thaum koj muab qhov hnyav ntau dhau rau ib yam dab tsi, lub plhaub tau kub dhau thiab tsis kav ntev.

Kev sib cuag ncaj qha ntawm cov cua sov xaim, siab - ntom MgO, thiab cov hlau sheath tso cai rau cov cua sov xa mus zoo nrog tsawg dua thermal lag, uas ua rau cov cua kub ceev.

Lub zog muaj zog thiab kev txhim kho yooj yim: Lub steel hlau tsis muaj zog tuaj yeem ua rau lub cev muaj zog thiab yooj yim rau zeb, vuam, lossis ntxiv cov xov, flanges, lossis lwm yam fittings kom yooj yim thiab ruaj ntseg kev koom ua ke rau hauv cov khoom siv.

Tus nqi zoo: Stainless hlau rhaub yog ib qho kev ntseeg siab heev thiab tus nqi -kev xaiv zoo rau feem ntau cov kev lag luam thiab kev lag luam cua sov xav tau. Lawv muaj dav thiab pheej yig piv rau cov kws kho mob tshwj xeeb xws li titanium, Inconel®, lossis Teflon®.

Cov kev txwv tseem ceeb thiab kev ntsuas kev nyab xeeb rau kev ua haujlwm

Txhawm rau kom cov khoom muaj kev nyab xeeb thiab kav ntev li ntev tau, yuav tsum tau ua raws li cov cai hauv qab no.

Chloride Stress Corrosion thiab High -Tub Degradation: Ua siab tshaj 500℃rau lub sijhawm ntev tuaj yeem ua kom oxidation thiab scaling. Cov pa 304/316 stainless hlau feem ntau yuav tawg nyob rau hauv kev ntxhov siab hauv cov chaw nrog cov tshuaj chloride (txawm tias me me los ntawm dej lossis huab cua) ntawm qhov kub ntawm 60℃thiab 200 degree. Qhov chaw ua haujlwm tshwj xeeb yuav tsum raug coj mus rau hauv tus account thaum xaiv cov khoom siv.

Fouling thiab Scaling nyob rau hauv Hard Dej / Kua: Thaum koj tshav kub cov dej los yog cov txheej txheem dej, cov ntxhia nplai ntawm lub sheath ua raws li ib tug thermal insulator. Qhov no ua rau cov cua sov sab hauv cov hlau ua haujlwm ntawm qhov kub siab dua los muab cov khoom tso tawm tib yam, uas ua rau muaj cua sov hauv cheeb tsam, xaim tsis ua haujlwm, thiab ua haujlwm tsis zoo. Koj yuav tsum tsis tu ncua descale lossis pretreat cov xov xwm.

Feem ntau yog vim li cas rau lub tshuab rhaub cartridge ua tsis tau tam sim ntawd yog siv nws sab nraud ntawm nws cov cua sov uas pom zoo -dissipating nruab nrab (cua, kua, lossis khoom). Fouling and Scaling in Hard Water/Liquids: Mineral scale on the sheath functions as a thermal insulator when hard water or process fluids are rated. Qhov no ua rau cov cua sov sab hauv cov hlau ua haujlwm ntawm qhov kub siab dua los muab cov khoom tso tawm tib yam, uas ua rau muaj cua sov hauv cheeb tsam, xaim tsis ua haujlwm, thiab ua haujlwm tsis zoo. Koj yuav tsum tau ntxuav lossis kho qhov nruab nrab tsis tu ncua.

Qhov feem ntau yog vim li cas lub tshuab rhaub dej kub tsis ua hauj lwm tam sim ntawd yog thaum nws siv hauv cov cua sov -dissipating media uas nws tsis tau tsim rau (xws li cua, kua, lossis khoom).

Nyob rau hauv xaus, stainless hlau cartridge rhaub yog ib tug saj zawg zog thiab pheej yig txoj kev rau cua sov khoom. Lawv qhov kev ua tau zoo thiab kev ua neej nyob yog nyob ntawm kev xaiv cov khoom tsim nyog, ua raws li cov txheej txheem thauj khoom saum npoo av, thiab zam kev ua haujlwm tsis zoo xws li qhuav- tua hluav taws thiab nyob hauv ib puag ncig corrosive uas tsis sib haum nrog lawv.
