Lead Wires - Qhov Txuas Tsis Muaj zog tshaj plaws hauv Ultra-High-Tsuas Kub
Lub tshuab rhaub cartridge ua tsis tiav. Cov ntaub qhwv zoo li zoo. Resistance coil checks tawm. Tab sis lub rhaub yuav tsis muaj zog. Qhov teeb meem tsis yog nyob rau hauv lub rhaub nws tus kheej - nws yog nyob rau hauv lub leads.
Cov hlau lead yog qhov tsis zoo tshaj plaws hauv cov tshuab cua sov, tshwj xeeb tshaj yog ntawm 950 degree. Standard txhuas hlau rwb thaiv tsev-feem ntau fiberglass- tsuas yog ntsuas rau 250℃xwb. Nyob rau ntawm 950℃sheath kub, cov leads tawm lub rhaub yog raug tshav kub heev. Yog tsis muaj kev tiv thaiv zoo, lub rwb thaiv tsev degrades, cov conductors oxidize, thiab kev sib txuas tsis ua haujlwm.
Kev daws yuav tsum tau ua tib zoo saib ntawm ntau theem. Ua ntej, cov hlau lead nws tus kheej yuav tsum tau ntsuas rau qhov kub thiab txias. Ntshiab npib tsib xee 高温线 (siab-kub hlau) feem ntau yog ntsuas rau 600℃. Rau qhov kub ntau dua, cov hlaws ceramic rwb thaiv tsev tuaj yeem tiv taus 700-800 degree. Qee cov tuam txhab lag luam muab cov hlaws ceramic uas tawm ncaj qha tawm ntawm cov hlau lead kawg lossis ntawm 90 degrees los ntawm lub plhaub. Alumina ntses qaum hlaws hlaws- interlocking ceramic insulators- tiv thaiv liab qab conductors nyob rau hauv ob qho tib si huab cua - sab thiab nqus tsev vacuum - sab siab - kub sib dhos.
Qhov thib ob, qhov chaw tawm ntawm cov hlau lead yuav tsum tau tsim los ua kom cov hlau lead txias li sai tau. Ib ntu uas tsis muaj cua sov ntawm lub tshuab cua sov ncua deb ntawm thaj chaw rhuab tso cai rau kev khiav ntawm qhov kub zoo dua. Rau ultra-siab- daim ntawv thov kub, qhov txias kawg ntev-feem ntau yog 50–100mm nyob ze ntawm cov coj- yuav tsum tau txuas ntxiv kom muab cov cua sov txaus. Qhov kawg txias yuav tsum nyob sab nraum qhov siab - qhov kub thiab txias kom tiv thaiv kev laus sai.
Thib peb, kev sib txuas hluav taws xob yuav tsum muaj kev ruaj ntseg. Kev sib txuas xoob ua rau muaj kev tiv thaiv kev tiv thaiv, ua kom muaj cua sov ntxiv uas tuaj yeem ua rau cov terminals thiab cov khoom nyob ib puag ncig puas. Tshaj -tightening kuj tuaj yeem ua rau lub davhlau ya nyob twg puas tsuaj thiab tsim cov ntsiab lus kev ntxhov siab uas tawg thaum caij tsheb kauj vab. Siv calibrated torque cov cuab yeej thiab xyuas nruj tom qab thawj lub voj voog cua sov-thaum thermal expansion tej zaum yuav cuam tshuam rau kev ncaj ncees kev sib txuas- tiv thaiv cov teeb meem no.
Thib plaub, kev tawm dag zog yog qhov tseem ceeb. Txoj kev coj mus deb ntawm cov tshuab txav, cov npoo ntse, thiab qhov chaw kub. Muab cov kev lim dej txaus kom tiv thaiv kev sib txuas ntawm lub davhlau ya nyob twg los ntawm kev rub los yog kev ntxhov siab. Khaws qhov tsawg kawg nkaus khoov radii teev los ntawm cov chaw tsim khoom kom tiv thaiv tus neeg xyuas pib qaug zog. Tiv thaiv cov hmoov txhuas los ntawm cov khoom paug-xws li roj thiab txhaj tshuaj molding tshuab spouts- kuj tseem ua rau lub neej ntev.
Moisture ingress los ntawm cov hlau lead yog lwm qhov kev txhawj xeeb. Cov ntsaws ruaj ruaj ntawm cov cua sov feem ntau yog ntxeem tau, thiab siab - qhov kub ntawm cov hlau lead hlau rwb thaiv tsev yuav ua rau cov dej noo nkag mus rau hauv lub rhaub. Yuav tsum muaj lub foob dej noo rau ob lub rhaub nws tus kheej thiab cov hlau lead hlau rwb thaiv tsev kom tiv thaiv cov dej nkag hauv cov kua lossis vapor daim ntawv. Rau cov ntawv thov cuam tshuam nrog kev ya raws, cov hlau lead tsim tsim nrog ceramic lossis TIG-welded kawg discs tiv thaiv kom tsis txhob muaj kab mob thiab ya raws los ntawm kev nkag mus rau hauv lub tshuab rhaub dej kub.
Raws li kev paub dhau los, cov hlau lead tsis ua haujlwm rau ib feem tseem ceeb ntawm cov khoom siv hluav taws xob cua sov hu. Cov hlau lead yog raug tshav kub, mechanical stress, thiab ib puag ncig cov pa phem -tag nrho thaum yog ib feem siv tau tshaj plaws ntawm lub kaw lus rau kev soj ntsuam thiab tu. Kev tshuaj xyuas tsis tu ncua ntawm cov hlau lead rau discoloration, cracking, los yog puas, ua ke nrog kev xaiv cov hlau lead thiab installation, tiv thaiv ntau yam ntawm cov tsis ua hauj lwm. Thaum ua tsis tiav, tag nrho cov cua sov system nres. Tiv thaiv cov thawj coj tiv thaiv kev nqis peev.
