Cartridge rhaub cov ntaub ntawv: Yuav ua li cas sheath thiab rwb thaiv tsev cuam tshuam kev ua tau zoo
Cov tswv lag luam feem ntau tsom rau wattage thiab voltage thaum xaiv lub tshuab rhaub cartridge, tab sis cov ntaub ntawv siv hauv lub tshuab rhaub lub plhaub thiab cov rwb thaiv tsev yog qhov tseem ceeb rau kev ua haujlwm thiab kev ua neej. Cov ntaub ntawv tsim nyog tuaj yeem ua kom muaj kev hloov pauv hluav taws xob zoo, tiv thaiv corrosion thiab kub siab, thiab kev cia siab ntev ntev -. Cov ntaub ntawv tsis raug, ntawm qhov tod tes, tuaj yeem ua rau ua tsis tiav ntxov, kev puas tsuaj ntawm cov khoom siv, thiab nce nqi kho. Qhov no yog qhov tseeb tshwj xeeb tshaj yog rau high voltage 800V cartridge heaters, uas ua haujlwm ntawm qhov kub siab dua thiab lub zog hluav taws xob, muab kev ntxhov siab ntau dua rau ntawm lub tshuab rhaub cov khoom.
Lub tshuab hluav taws xob lub tshuab hluav taws xob yog cov txheej txheem hlau sab nraud uas tuaj yeem cuam tshuam ncaj qha nrog cov khoom siv lossis ib puag ncig. Nws ua haujlwm rau ob lub hom phiaj tseem ceeb: hloov cov cua sov los ntawm cov coil sab hauv mus rau cov khoom siv lub hom phiaj thiab tiv thaiv cov khoom sab hauv los ntawm kev sib kis, corrosion, thiab kev puas tsuaj rau lub cev. Qhov kev xaiv ntawm cov khoom siv sheath nyob ntawm qhov kev khiav hauj lwm kub, ib puag ncig, thiab daim ntawv thov. Raws li kev paub dhau los, feem ntau cov ntaub ntawv sheath rau lub tshuab cua sov yog stainless hlau, incoloy, thiab titanium.
Stainless hlau yog cov khoom siv dav siv ntau tshaj plaws rau cov txheej txheem cartridge rhaub. Nws muaj qhov zoo corrosion kuj, nruab nrab kub kam rau ua (txog 500 degree), thiab tus nqi -effectiveness. Stainless hlau yog qhov zoo tshaj plaws rau kev siv dav dav - lub hom phiaj xws li yas molding, ntim, thiab cov khoom siv hauv chav kuaj, qhov kub thiab qhov chaw tsis muaj corrosive. Txawm li cas los xij, stainless hlau tej zaum yuav tsis haum rau siab - daim ntawv thov kub lossis ib puag ncig hnyav, vim nws tuaj yeem degrade dhau sijhawm.
Incoloy yog lub siab-kub alloy uas tuaj yeem tiv taus qhov kub thiab txias txog li 760 degree, ua rau nws zoo tagnrho rau kev siv kub xws li kev siv hlau, kev ua cov khoom siv hluav taws xob, thiab cov qhov cub ua haujlwm. Incoloy kuj muaj kev tiv thaiv corrosion zoo heev, ua rau nws tsim nyog rau kev siv tshuaj lom neeg ua cov nroj tsuag lossis thaj chaw marine. High voltage 800V cartridge heaters feem ntau siv incoloy sheaths, raws li lawv muaj peev xwm tswj tau qhov kub siab dua uas tsim los ntawm cov cua sov no thiab muab lub sijhawm ntev -.
Titanium yog cov khoom siv tiv thaiv corrosion tshaj plaws, ua rau nws zoo tagnrho rau hnyav, corrosive ib puag ncig xws li kev ua tshuaj, dej ntsev, thiab kev tsim tshuaj. Titanium tuaj yeem tiv taus qhov kub txog li 400℃thiab tiv taus cov kua qaub, alkalis, thiab dej ntsev. Thaum titanium yog kim dua stainless hlau los yog incoloy, nws muaj superior durability nyob rau hauv corrosive ib puag ncig, txo qhov yuav tsum tau rau nquag hloov.
Cov khoom siv rwb thaiv tsev hauv lub tshuab cua sov yog qhov tseem ceeb ib yam li cov ntaub qhwv. Rwb thaiv tsev yog lub luag hauj lwm rau muaj cov cua kub uas tsim los ntawm lub hauv paus coil thiab tiv thaiv hluav taws xob to, tshwj xeeb tshaj yog rau high voltage 800V cartridge heaters. Cov khoom siv rwb thaiv tsev zoo tshaj plaws rau lub tshuab cua sov yog magnesium oxide (MgO), cov khoom siv ceramic uas muaj cov thermal conductivity zoo thiab hluav taws xob rwb thaiv tsev. MgO tuaj yeem tiv taus qhov kub thiab txias (txog 1000 degree) thiab tiv taus cov dej noo thiab tshuaj lom neeg puas tsuaj.
Txawm li cas los xij, MgO rwb thaiv tsev yuav tsum tau ua kom zoo thaum lub sij hawm tsim khoom los xyuas kom meej qhov ua tau zoo. Kev cog lus tsis zoo MgO tuaj yeem tsim qhov sib txawv ntawm huab cua, uas txo cov thermal conductivity thiab ua rau muaj kev pheej hmoo ntawm hluav taws xob. Rau high voltage 800V cartridge heaters, siab -zoo, compacted MgO rwb thaiv tsev yog qhov tseem ceeb los tiv thaiv rwb thaiv tsev tawg thiab hluav taws xob luv. Qee qhov tshwj xeeb cartridge rhaub siv ceramic fiber rwb thaiv tsev rau qhov kub thiab txias, tab sis qhov no tsis tshua muaj rau cov qauv siv.
Cov khoom siv cua sov sab hauv kuj cuam tshuam kev ua haujlwm. Feem ntau cov tshuab tso cua sov siv nickel-chromium (NiCr) lossis hlau -chromium- txhuas (FeCrAl) coils. NiCr coils muaj qhov ua haujlwm zoo rau qhov kub thiab txias thiab oxidation, ua rau lawv haum rau nruab nrab -kev siv kub. FeCrAl coils muaj qhov kub siab dua (txog 1200 degree) thiab zoo dua oxidation tsis kam, ua rau lawv zoo tagnrho rau siab - kub daim ntawv thov thiab high voltage 800V cartridge heaters.
Xaiv cov ntaub qhwv thiab cov ntaub ntawv rwb thaiv tsev rau lub tshuab cua sov yog nyob ntawm daim ntawv thov kev ua haujlwm kub, ib puag ncig, thiab kev ua haujlwm. Rau kev siv dav dav - lub hom phiaj siv, stainless hlau sheath nrog MgO rwb thaiv tsev yog txaus. Rau siab -kev siv kub, incoloy sheath nrog FeCrAl coil thiab compacted MgO rwb thaiv tsev yog pom zoo. Rau corrosive ib puag ncig, titanium sheath yog qhov kev xaiv zoo tshaj plaws. Rau siab voltage 800V cartridge heaters, incoloy los yog titanium sheath nrog siab - zoo MgO rwb thaiv tsev yog qhov tseem ceeb los tswj lub siab zog thiab kub theem.
Cov ntaub ntawv siv hauv lub tshuab hluav taws xob cartridge ncaj qha cuam tshuam nws qhov kev ua tau zoo, lub neej ntev, thiab kev ntseeg tau. Kev saib xyuas qhov tseem ceeb ntawm cov ntaub qhwv thiab cov ntaub ntawv rwb thaiv tsev tuaj yeem ua rau ua tsis tiav ntxov thiab nce nqi. Rau kev lag luam kev lag luam xaiv lub tshuab cua sov-txawm tus qauv lossis cov qauv hluav taws xob siab 800V- xav txog qhov chaw ua haujlwm, qhov kub thiab txias, thiab kev tiv thaiv corrosion yog qhov tseem ceeb ntawm kev xaiv cov ntaub ntawv zoo. Kev cob qhia kws tshaj lij tuaj yeem pab ntsuam xyuas cov kev xav tau tshwj xeeb ntawm daim ntawv thov thiab pom zoo kom pom cov ntaub qhwv, rwb thaiv tsev, thiab cov ntaub ntawv coil rau kev ua haujlwm siab tshaj plaws thiab ua haujlwm ntev.
