Thermocouple qhib Circuit Court yog ib qho teeb meem tshwm sim sai tshaj plaws nyob rau hauv cov kev cob qhia kub khiav, tshwm sim raws li tus maub los qhia "OPEN" lub tswb, qhov sib thooj cua sov kom tsis txhob muaj cua sov tag, ua rau cov khoom txias, ua tsis tiav thiab kaw cov pwm. Qhib Circuit Court tsis ua hauj lwm qhov tseem ceeb yog hais txog kev tawg ntawm sab hauv zoo thiab tsis zoo thermoelectric alloy xov hlau los yog kev cuam tshuam ntawm cov ntsiab lus ntawm lub davhlau ya nyob twg, uas tuaj yeem muab faib ua tsib lub hauv paus ua rau: mechanical tensile fracture, sheath extrusion cracking, high-temperature oxidation wire breakage, terminal loose fall-off and improper cutting. Formulating standardized installation thiab niaj hnub soj ntsuam specifications yuav txo tau qhov tshwm sim tshwm sim ntawm qhib Circuit Court txhaum los ntawm ntau tshaj 90%.
Mechanical nro kev puas tsuaj rau ntau tshaj ib nrab ntawm qhib Circuit Court raug mob. Thaum lub pwm qhib thiab kaw, lub manifold yuav nthuav dav thiab cog lus nrog kev hloov pauv kub, thiab cov pwm phaj yuav tsim tawm. Yog hais tias lub thermocouple hlau yog tsau nruj heev yam tsis muaj qhov ntev slack, nruam tensile quab yuam yuav ua rau MI sheath thiab cov hlau alloy sab hauv lub sijhawm ntev, ua rau qaug zog tawg tom qab ntau txhiab lub voj voog molding. Cov txheej txheem kev ua haujlwm tshwj xeeb yuav tsum tau tshwj tseg tsawg kawg 100 hli ntawm cov xaim xoob ntawm qhov hluav taws xob ntawm txhua qhov kub khiav sensor, thiab siv siab - kub hlau clamps los kho cov hlua khi ntawm cov pwm pwm es tsis txhob txuas ncaj qha rau MI sheath. Rau cov pwm loj uas muaj pwm qhib stroke ntau dua 500mm, hloov tau lub caij nplooj ntoos hlav hlau tiv thaiv lub tes tsho yuav tsum tau ntxiv rau sab nraum lub thermocouple txuas xov hlau kom tsis txhob rub lub zog thaum pwm txav.
Extrusion tawg ntawm cov hlau sheath yog lwm qhov loj inducement ntawm qhib circuits. Thaum sib sau ua ke cov manifold, nruj nreem clamping bolts nyuaj heev yuav tsoo lub nyias MI sheath faus rau hauv qhov sib txawv ntawm cov hlau phaj, txiav tawm cov hlau alloy sab hauv. Ntau tus neeg ua haujlwm sib dhos tsis quav ntsej cov hlau routing groove thiab ncaj qha nias lub thermocouple hlau nyob rau hauv lub manifold nias phaj thaum lub sij hawm pwm mus sib hais. Kev tiv thaiv kev tiv thaiv yog ua kom tiav ib qho tshwj xeeb 3 hli - dav hlau zawj ntawm cov pwm phaj rau tag nrho cov xov hlau sensor, thiab nteg siab - kub asbestos gaskets hauv qhov zawj kom cais cov hlau nyuaj. Nws yog txwv tsis pub npaj cov xaim thermocouple ntawm qhov chaw sib cuag ntawm cov ntawv qhia pins thiab ejector daim hlau kom tsis txhob muaj kev sib txhuam txiav cov sheath thaum lub sij hawm pwm txav.
Ntev -lub sij hawm siab- kub oxidation hlau tawg feem ntau tshwm sim ntawm qis- nqi J- hom patch thermocouples siv saum 300℃. Cov hlau-raws li alloy hlau yog oxidized sai heev nyob rau hauv siab kub thiab corrosive yas roj, thiab cov hlau txoj kab uas hla yuav thinner mus txog rau thaum nws tawg. Rau cov kab ntau lawm nrog molding kub tshaj 280 degree, MI K- hom thermocouples nrog tag nrho cov ntaub qhwv yuav tsum tau hloov ua ntej kom tsis txhob qhib Circuit Court kaw thaum lub sij hawm ntau lawm. Terminal disconnection faults yog concentrated nyob rau hauv ntau- cheeb tsam pwm nrog nquag hloov sensor; cov tooj liab terminals ntawm lub xaim kawg tsis yog crimped ruaj khov, los yog cov ntsia hlau ntawm tus tswj lub davhlau ya nyob twg thaiv yog xoob, ua rau kev sib txuas virtual thiab qhib Circuit Court tom qab kev co. Cov txheej txheem tshuaj xyuas niaj hnub xav kom cov kws tshaj lij yuav tsum tsis tu ncua rov- nruj tag nrho cov thermocouple terminal screws ua ntej pib lub tshuab txhua tag kis.
Kev saib xyuas tsis raug yog ib qho tib neeg- cuam tshuam qhib Circuit Court txhaum uas yooj yim tsis quav ntsej. Thaum hloov lub tshuab rhaub manifold, cov neeg ua haujlwm feem ntau txiav cov thermocouple xaim los ntawm kev ua yuam kev yam tsis tau kos npe rau txoj haujlwm. Txoj cai tswj xyuas tus qauv yog sau txhua lub thermocouple hlau nrog ib cheeb tsam tus lej ua ntej disassembly, thiab qhwv cov hlau txuas nrog siab -kab nplaum nplaum rau kev tiv thaiv. Kev saib xyuas txhua lub limtiam ntxiv cov ntsuas ntsuas txuas txuas txuas ntxiv rau txhua qhov ntsuas kub: teeb lub multimeter rau ntawm -tawm iav, yog tias tsis muaj kev nrov nrov, nws txhais tau hais tias cov xov hlau sab hauv tau tawg, thiab lub ntsuas faulty tuaj yeem hloov ua ntej ua ntej kev tsim khoom, tshem tawm lub tswb nrov qhib Circuit Court uas cuam tshuam lub sijhawm tsim khoom.
