Loj tuab-phab ntsa automotive pwm rau cov kab hluav taws xob, cov roj teeb vaj tse thiab cov cuab yeej siv hluav taws xob txhawb nqa cov khoom loj loj sib faib manifolds, thermal loj loj, lub voj voog ntev cua sov thiab cov iav fiber ntau txhawb siab -kub resins. Cov qauv txheej txheem thermocouples tsis tuaj yeem phim qhov hloov pauv cua sov qeeb, muaj zog corrosive gas thiab thermal expansion cov yam ntxwv ntawm cov pwm no, ua rau qeeb cov teeb liab teb, kub kub oxidation sai thiab tsis ruaj khov rau lub caij nplooj ntoos hlav. Dedicated customized thermocouple qauv npog cov ntaub ntawv sheath, teb ceev, lub caij nplooj ntoos hlav qauv thiab thaiv layout yuav tsum tau raws li ntev - voj voog 24-teev nruam ntau lawm thov rau automotive structural Cheebtsam.
Ua ntej, siab -kub siab - nthuav dav sib piv cov hlau sheath cov qauv. Automotive tuab-phab ntsa manifolds yog ua los ntawm H13 kub ua hauj lwm hlau nrog ib tug linear expansion coefficient ntawm 12.8 × 10⁻⁶ /℃. Ordinary 304 thiab 316L stainless hlau sheaths muaj qhov nthuav dav ntau dua, tsim kom muaj kev sib zog ntau dhau ntawm kev tsim- nyob rau hauv cov springs thaum cua sov thiab ua rau elastic qaug zog drift nyob rau hauv 2-3 lub hlis. Tag nrho cov automotive tuab tuab -phab ntsa pwm thermocouples txais seamless Hastelloy alloy sheaths nrog ib tug sib piv expansion coefficient ntawm 12.9 × 10⁻⁶ / degree, txo qhov sib txawv ntawm qhov sib txawv ntawm sheath thiab manifold mounting qhov nyob rau hauv tag nrho cov kub ntau yam. Hastelloy kuj tseem muab cov kev tiv thaiv zoo tshaj rau cov kua qaub halogen roj tso tawm los ntawm iav fiber reinforced PA, PPA thiab nplaim taws -PC retardant, tiv taus pitting corrosion txawm nyob rau hauv 340℃ntev -lub sij hawm ua hauj lwm kub. Lub sheath phab ntsa thickness yog nce mus rau 1.8mm los tiv thaiv kev sib txhuam hnav los ntawm kev rov qab thermal expansion thiab contraction ntawm tuab manifold steel daim hlau.
Thib ob, nruab nrab- teb ceev ceev 1.5mm ntxhia- insulated sojntsuam tsim rau loj thermal mass manifolds. Ultra-nyias 0.5–1.0mm me me probes tsis haum rau loj tuab manifolds nrog loj heev kub cia; lawv cov junctions kub me me tsis tuaj yeem ntes qhov nruab nrab manifold kub ntawm qhov tsis sib xws thaum tshav kub kub. Tshaj - tuab 3.0mm sojntsuam nqa cov cua kub ntau dhau thiab raug teeb meem loj heev, ncua kev hloov PID fais fab thiab ua rau tuab- phab ntsa sab hauv voids thiab cov cim dab dej. Lub 1.5mm nyias-phab ntsa MI sojntsuam tawm tsam qhov zoo tshaj plaws: qhov nruab nrab thermal huab hwm coj ua kom nws muaj kev cuam tshuam tag nrho cov manifold kub, thaum lub tshuab nqus tsev vacuum- kaw qhov kub kub junctions txiav cov lus teb qeeb qis dua 0.4 vib nas this, ua kom lub zog kho raws sij hawm kom sib npaug ntawm cov cua sov hauv cov tuab tuab. Txhua qhov kev sojntsuam txais tag nrho lub caij nplooj ntoos hlav bayonet qauv nrog 2mm ntxiv compression stroke kom them me me nthuav dav ntawm cov pwm qhov loj.
Thib peb, hnyav-lub luag haujlwm tiv thaiv- qaug zog caij nplooj ntoos hlav specifications yoog mus rau lub caij ntuj sov tsis tu ncua. Automotive tuab-phab ntsa pwm feem ntau ua rau txhua hnub ua kom txias tag nrho tom qab kev hloov pauv ntau lawm, ua rau muaj kev kub ntxhov siab heev. Standard stainless hlau springs poob elasticity sai sai nyob rau hauv rov qab loj- ntau compression thiab rebound. Kev cai springs siv siab -kub Inconel alloy nrog 40% siab tensile zog tshaj lub caij nplooj ntoos hlav zoo tib yam, nrog passivated los tiv thaiv -corrosion nto kho kom tiv thaiv cov roj acid yaig. Lub caij nplooj ntoos hlav coil hlau txoj kab uas hla yog thickened mus rau 0.35mm, ncua kev pab cuam lub neej nyob rau hauv 24-teev cyclic thermal shock mus rau ntau tshaj rau lub hlis yam tsis muaj qaug zog vim huab cua sib txawv drift.
Plaub, ntev -nruab deb tiv thaiv- attenuation thaiv kev teeb tsa rau pwm loj layout. Lub tsheb loj pwm yuav tsum tau thermocouple cables ntev dua 12 meters kom ncav cuag sab nraud hlws ris thawv sab nraum cov pwm loj. Tag nrho cov teeb liab cables txais yuav tuab-core bidirectional cross-twisted ob-txheej txheej tiv thaiv nrog braiding ntom saum 95%, txo cov kab tsis kam thiab tshem tawm qhov ntev -cov teeb liab attenuation. Independent insulated threading pipes cais cov thermocouple cables los ntawm siab -tam sim no lub tshuab rhaub fais fab kab los ntawm ntau tshaj 50mm los thaiv servo electromagnetic cuam tshuam. Pwm-sab digital hloov pauv modules tau teeb tsa rau kev xaim ntau dua 15 meters los hloov cov teeb liab analog rau hauv cov ntaub ntawv digital thiab tshem tawm tag nrho cov kev sib kis tsis hais txog ntawm cable ntev.
Thib tsib, txuas ntxiv qhov sib txawv ntawm kev tu lub voj voog sib tw nrog siab -load tsheb ntau lawm. Dedicated thermocouples rau tuab-phab ntsa automotive pwm ua haujlwm nyob rau hauv ultra- siab load corrosive ib puag ncig, yuav tsum tau disassembly tu ob lub lis piam ntawm kub hlws ris carbon deposits thiab bi- hli peb- taw tes sib piv calibration. Kev hloov pauv tag nrho yog teem sijhawm txhua tsib lub hlis, ib hlis ua ntej tshaj li tus qauv siv hluav taws xob pwm sojntsuam. Thaum lub sij hawm pwm overhaul txhua hli, cov kws kho mob yuav tsum tau tshuaj xyuas qhov chaw ntawm qhov chaw sib txhuam thiab lub caij nplooj ntoos hlav rov ua haujlwm; tej kev sojntsuam nrog indentation deformation lossis qeeb lub caij nplooj ntoos hlav pib dua tshiab tau hloov ua ntej kom tsis txhob zais qhov kub thiab txias thaum lub sijhawm tsim khoom loj hauv tsheb.
Kev ua raws li cov tsheb tuab tuab -cov qauv phab ntsa thermocouple customization qauv stabilizes multi-section manifold kub sib npaug, tshem tawm tuab-phab ntsa molding tsis xws luag xws li sab hauv shrinkage voids thiab qhov tsis sib xws ntawm qhov ntev, thiab txuas ntxiv qhov nruab nrab qhov kev pab cuam lub neej ntawm 3 corroshtemper ntau lawm - ib puag ncig.
