Niaj hnub no, peb yuav ua kom paub tus qauv hom cartridge rhaub, ib qho kev daws teeb meem rau pwm cua sov.
Nws yog cov khoom siv hluav taws xob cua sov tsim rau cov cua sov pwm thiab cov cuab yeej siv tshuab ntawm ntau qhov ntau thiab tsawg.
Nws cov khoom tseem ceeb muaj xws li: 1. Stainless hlau sheath, 2. Magnesium oxide (MgO) rwb thaiv tsev hmoov, 3. Resistance cua sov hlau, 4. Magnesium oxide compacted core, 5. High-cov ntaub ntawv ceev insulating, 6. Terminal pin / lead pas nrig, 7. High - kub, thiab lwm yam.
Txheem txheej diameters feem ntau yog nyob ntawm 3 hli mus rau 30 hli, nrog ntev muaj los ntawm luv li 10 hli mus rau tshaj 1000 hli. Vim qhov sib txawv ntawm kev xaiv cov khoom siv thiab cov txheej txheem tsim khoom, qhov zoo ntawm cov khoom siv hluav taws xob tuaj yeem sib txawv ntawm cov neeg muag khoom. Qhov tseem ceeb sib txawv feem ntau suav nrog lub zog ceev, lub zog dielectric, qhov tseeb qhov tseeb, thiab lub neej ua haujlwm.
Cartridge heaters feem ntau muab faib ua ob qhov kev teeb tsa: Internal Lead thiab External Lead.
Sab nraud Lead Hom:
Lub davhlau ya nyob twg tus pin/lead pas nrig txuas sab nraud mus rau qhov siab -kub cov hlau lead ntawm lub davhlau ya nyob twg thaiv.
Internal Lead Hom:
Qhov siab -kub cov hlau lead yog txuas ncaj qha mus rau cov hlau tsis muaj zog hauv lub tshuab cua sov thiab tawm los ntawm hauv lub plhaub nws tus kheej.
Qhov sib txawv ntawm cov txheej txheem tsim khoom:
Cov txheej txheem tsim khoom rau ob hom no txawv. Hauv kev tsim cov hlau lead sab nraud, cov xaim hluav taws xob sab hauv yog welded rau lub davhlau ya nyob twg tus pin hauv lub sheath, uas tom qab ntawd txuas nrog sab nraud rau cov hlau lead. Hauv kev tsim cov hlau lead hauv, cov hlau lead yog ncaj qha welded rau cov hlau tsis kam nyob rau hauv lub kaw kawg ntawm lub sheath.
Lead Wire Temperature Rating:
Rau cov khoom siv lead ua sab nraud, txij li qhov taw qhia kev sib txuas yog sab nraud, qhov kub ntawm qhov sib koom ua ke yog qis dua, thiab cov hlau lead feem ntau tsuas yog yuav tsum tau tiv taus qhov kub thiab txias txog li 250 degrees. Rau cov khoom siv sab hauv, cov hlau lead yog muab tso rau hauv thaj chaw kub nyob ze ntawm cov hlau tsis muaj zog thiab yog li yuav tsum tiv taus qhov kub thiab txias ntau dua (tsawg kawg 800 degree), feem ntau xav tau cov ntaub ntawv zoo li cov nickel ntshiab, uas nce nqi.
Creepage(qhov kev ncua deb tshaj plaws ntawm ob qhov hluav taws xob, lossis nruab nrab ntawm ib feem ntawm cov khoom siv hluav taws xob thiab cov khoom siv tiv thaiv lub ntiaj teb, ntsuas raws li qhov chaw ntawm cov khoom siv insulating)thiab Clearance:
Los ntawm kev xav txog kev nyab xeeb hluav taws xob, tshwj xeeb tshaj yog hais txog kev nkag mus deb, kev tsim kho hauv cov hlau lead feem ntau muaj kev nyab xeeb dua.
Kev Ua Haujlwm Zoo:
Cov txheej txheem tsim khoom rau cov khoom siv lead ua sab hauv yog qhov nyuaj thiab lub sijhawm siv ntau dua -, tshwj xeeb tshaj yog cov txheej txheem vuam sab hauv. Yog li ntawd, nws cov efficiency ntau lawm feem ntau qis dua thiab lub sij hawm ua cov hmoov txhuas ntev dua piv rau lwm hom hlau lead.
Cartridge heaters yog cov khoom siv hluav taws xob tshwj xeeb tsim los hloov hluav taws xob hluav taws xob rau hauv tshav kub. Lawv tau txais kev pom zoo thoob plaws ntau yam kev siv cua sov vim lawv cov nqi qis, kev yooj yim ntawm kev teeb tsa, kev teb thermal sai, thiab kev ua haujlwm huv.
Nyob rau hauv ib tug txheej txheem cartridge rhaub, lub siab - kub tsis kam hlau yog uniformly faib nyob rau hauv ib tug siab - qib, seamless stainless hlau raj. Cov khoob khoob yog ntim nrog crystalline magnesium oxide hmoov, uas muaj cov thermal conductivity zoo heev thiab hluav taws xob rwb thaiv tsev. Qhov kev tsim kho no tsis yog tsuas yog ua tau zoo thiab txhim khu kev qha, tab sis kuj txhawb kev hloov cov cua sov kom zoo.
Thaum cov hluav taws xob tam sim no dhau los ntawm cov hlau tsis kam, cov hluav taws xob tsim hluav taws xob yog ua los ntawm magnesium oxide hmoov rau saum npoo ntawm cov hlau sheath. Los ntawm qhov ntawd, nws raug xa mus rau cov khoom tau rhuab los yog qhov nruab nrab ib puag ncig, yog li ua tiav cov txiaj ntsig cua sov uas xav tau.
