HIGH-VOLTAGE POWER Supply Cartridge rhaub: HAUV TSEV THIAB ENGINEERING SOLUTIONS
Cov kab ntau lawm dheev kaw vim tias lub tshuab rhaub pwm ua tsis tiav, thiab qhov kev xav tam sim yog los liam lub rhaub nws tus kheej. Tab sis nyob rau hauv ntau qhov xwm txheej, tus neeg ua txhaum tiag tiag tsis yog kev tsim khoom tsis zoo, tab sis qhov chaw hluav taws xob uas lub rhaub ua haujlwm - tshwj xeeb tshaj yog thaum cuam tshuam nrog siab -voltage applications. High-voltage power supply cartridge heaters yog qhov tseem ceeb hauv ntau qhov chaw lag luam, tab sis lawv nthuav tawm cov kev sib tw tshwj xeeb engineering uas feem ntau tsis saib xyuas kom txog thaum muaj qee yam tsis raug.
A cartridge rhaubyog lub hauv paus ntawm lub tshuab hluav taws xob compact tsim kom haum rau hauv qhov tseeb machined bore. Cov hlau tsis kam yog qhov txhab nyob ib ncig ntawm cov tub ntxhais ceramic, nrog siab -purity magnesium oxide (MgO) sau qhov sib txawv ntawm cov hlau thiab cov hlau sheath. Qhov MgO no ua haujlwm rau ob lub hom phiaj: nws hluav taws xob insulates cov hlau tsis muaj zog los ntawm lub plhaub thaum ua kom muaj cua sov sab nraud rau daim ntawv thov. Hauv cov qauv qis-voltage configurations, qhov kev tsim no ua haujlwm tau zoo rau ntau txhiab lub voj voog. Txawm li cas los xij, thaum cov khoom siv hluav taws xob nce mus rau 220V, 380V, 480V, lossis siab dua, cov ceg txheem ntseeg hloov pauv ntau.
Cov ntawv thov uas xav tau siab -voltage power supply cartridge heaters muaj nyob thoob plaws ntau qhov kev lag luam xav tau. Yas txhaj tshuaj molding tshuab, kub khiav tshuab, ntim sealing khoom, tuag-casting machinery, thiab kuaj qhov cub kub kho txhua zaus hu rau siab -voltage cua sov. Cov ntawv thov no xav kom tswj tau qhov kub thiab txias thiab txhim khu kev qha zoo, vim tias txhua lub sijhawm downtime txhais ncaj qha rau hauv kev tsim khoom ploj thiab nce nqi.
Vim li cas qhov voltage tseem ceeb heev? Qhov teeb meem tseem ceeb yog nyob rau hauv kev sib raug zoo ntawm voltage, tam sim no, thiab lub zog. Nyob rau hauv ib tug resistive cua sov Circuit Court, qhov tsis kam ntawm lub rhaub yog tsau. Thaum voltage doubles, tam sim no doubles ib yam nkaus li - lub ntsiab lus fais fab quadruples. Qhov kev cuam tshuam no dhau los ua qhov tseem ceeb hauv high-voltage ib puag ncig. Dab tsi ntau tsis paub yog tias lub zog dielectric thiab to tam sim no ntawm acartridge rhaubraug cuam tshuam ncaj qha los ntawm kev siv hluav taws xob. Raws li kev khiav hauj lwm voltage nce, cov hluav taws xob kev nyuaj siab ntawm cov ntaub ntawv rwb thaiv tsev intensifies ho.
Los ntawm cov tswv yim tsim khoom, kev tsim cov siab -voltage cartridge heaters nyob rau hauv me me diameters yog qhov nyuaj tshwj xeeb. Raws li cov ntaub ntawv tsim los ntawm engineering, lub tshuab rhaub dej kub rau siab - cov ntawv siv hluav taws xob nrog cov txheej txheem stainless hlau sheath txoj kab uas hla ntawm ib - ib nrab nti lossis tsawg dua ib txwm muaj teeb meem loj txog kev puas tsuaj ntawm dielectric thiab cov teeb meem tam sim no. Rau cov cartridges me me, kev tsim khoom nruj nruj yog qhov nyuaj rau kev tswj xyuas dua. Lub ntsiab tseem ceeb uas tawm ntawm - nruab nrab los ntawm tsawg li 0.001 nti tom qab sau tuaj yeem cuam tshuam lub zog dielectric ntawm lub caij. Thickness, compaction, thiab ntom ntawm cov khoom muab tub lim yuav tsis txaus rau kev txhim khu kev qha dielectric zog ntawm qhov kub thiab txias ntawm lub rhaub. Ua ntej cov txheej txheem tsim tshwj xeeb raug tsim, siab -voltage cartridge heaters yog ib txwm muaj nyob rau hauv diameters loj dua ib -ib nrab ntiv tes, los yog ua hauj lwm tsim uas tsis tsim nyog rau daim ntawv pov thawj raws li cov qauv kev lag luam.
Cov txheej txheem tsim khoom niaj hnub tau kov yeej ntau ntawm cov kev txwv no. Kev siv cov khoom ua ntej-compacted insulating cov tes tsho nyob ib ncig ntawm lub coiled cua sov lub caij ua kom lub thickness thiab ntom ntawm MgO rwb thaiv tsev nyob twj ywm zoo ib yam - ib qho tseem ceeb rau siab -voltage reliability. Qhov kev tsim qauv no tso cai rau me me -inch siab-voltage heaters yam tsis muaj kev cuam tshuam txog kev nyab xeeb lossis kev ua haujlwm.
Thaum qhia lossis txhim kho acartridge rhaubrau siab - cov ntawv siv hluav taws xob, muaj ntau qhov kev txiav txim siab tseem ceeb. Ua ntej, xyuas kom meej tias cov rwb thaiv tsev ua tau raws li cov qauv xav tau. Rau qhov txias - lub xeev tej yam kev mob, ib qho kev tiv thaiv rwb thaiv tsev ntawm tsawg kawg yog 50 megohms feem ntau xav tau. Qhov thib ob, xyuas kom meej tias cov hlau lead hlau rwb thaiv tsev yog ntsuas rau tag nrho cov kev khiav hauj lwm voltage. Standard fiberglass los yog silicone rwb thaiv tsev tej zaum yuav tsim nyog rau qis voltages, tab sis siab -voltage daim ntaub ntawv feem ntau xav tau kev txhawb zog los yog tshwj xeeb rated rwb thaiv tsev systems. Kev paub qhia tau tias cov dej noo yog yeeb ncuab ntawm kev ua haujlwm siab -voltage. Txawm tias me ntsis noo noo nkag mus rau hauv MgO rwb thaiv tsev tuaj yeem txo cov dielectric lub zog thiab tsim kom muaj kev phom sij txaus ntshai tam sim no.
Kev ntsuam xyuas tsis yog -negotiable. Ua ntej energizing tej siab -voltage cartridge rhaub, ua ib tug tiav rwb thaiv tsev tiv thaiv kev xeem siv ib tug megohmmeter. Cov kauj ruam yooj yim no tuaj yeem tiv thaiv kev puas tsuaj loj thiab ua kom muaj kev nyab xeeb. Cov kev sib txuas ntawm cov hlau lead yuav tsum huv, nruj, thiab kaw kom zoo tiv thaiv cov dej noo thiab cov kab mob.
Lwm qhov kev txiav txim siab uas tau txais kev saib xyuas tsis txaus yog tus cwj pwm thermal expansion. High- lub tshuab hluav taws xob hluav taws xob feem ntau ua haujlwm ntawm qhov kub siab, thiab kev nthuav dav ntawm cov khoom siv sab hauv tuaj yeem cuam tshuam cov hluav taws xob tshem tawm. Tus tsim yuav tsum ua raws li qhov kev nthuav dav no yam tsis muaj kev cuam tshuam cov rwb thaiv tsev qhov sib txawv ntawm cov hlau tsis kam thiab cov sheath.
Cov lus pom zoo rau cov neeg siv high-voltage power supply cartridge heaters: ib txwm saib xyuas qhov zoo tshaj tus nqi thaum muaj hluav taws xob siab. Lub tshuab hluav taws xob pheej yig dua tuaj yeem txuag tau ob peb las pem hauv ntej, tab sis cov kev pheej hmoo cuam tshuam nrog dielectric tawg ntawm qhov hluav taws xob siab suav nrog cov khoom siv puas tsuaj, kev tsim khoom poob qis, thiab muaj peev xwm muaj kev nyab xeeb. Qhov sib txawv ntawm lub rhaub dej kub uas ua tau raws li qhov siab -voltage specifications thiab ib qho uas tsis ua kom pom tseeb hauv kev ua haujlwm ntev.
Nws tseem tsim nyog sau cia tias cov qauv kev nyab xeeb thoob ntiaj teb, xws li IEC 60519 series rau kev nyab xeeb hauv kev teeb tsa hluav taws xob, muab kev taw qhia rau cov hluav taws xob tiv thaiv cua sov, nrog rau cov kev khiav hauj lwm ntawm qhov siab voltages. Cov qauv no lees paub tias cov khoom siv hluav taws xob siab -voltage electroheat poob hauv qhov hluav taws xob ntau txog 3,600 V AC lossis 5,000 V DC, thiab ua raws li cov kev xav tau kev nyab xeeb dav dav rau cov kev teeb tsa no yog qhov tseem ceeb.
Hauv cov ntsiab lus, kev xa tawm siab -voltage power supply cartridge heaters yuav tsum tau ceev faj txog kev tsim, khoom siv, kev teeb tsa, thiab cov txheej txheem kuaj. Kev tsim vaj tsev tom qab cov cuab yeej siv cua sov no yog qhov tsim nyog, thiab txiav cov ces kaum ntawm ib qho ntawm cov kev xav no tuaj yeem ua rau ua tsis tiav ntxov thiab raug nqi ntau. Daim ntawv thov sib txawv - xws li los ntawm cov yas txhaj tshuaj pwm mus rau siab - qhov kub thiab txias - txhua qhov xav tau kev teeb tsa tshwj xeeb thiab xav tau kev tsim qauv tsim kom ua tiav qhov kev ua tau zoo thiab kev nyab xeeb.
