Kev saib xyuas tus qauv tsis tu ncua yog qhov kev lag luam zoo tshaj plaws kom txo tau tus nqi thermocouple tsis ua haujlwm, tsis txhob cia siab tias pwm kaw thiab txiav cov seem ntawm kev txhaj tshuaj molding rhiav. Cov tuam txhab lag luam feem ntau tsuas yog hloov cov thermocouples puas tom qab muaj teeb meem tshwm sim, tsis muaj kev tshuaj xyuas thiab kev saib xyuas tsis tu ncua, ua rau rov tshwm sim ntawm kev sib cuag tsis zoo, qhib Circuit Court thiab teeb liab faults. Tsab ntawv xov xwm no txheeb xyuas peb lub hlis twg, peb lub hlis twg thiab txhua xyoo peb- theem kev ua haujlwm tsis tu ncua ntawm cov thermocouples kub khiav, nrog rau txhua hnub ntawm - qhov chaw soj ntsuam cov ntsiab lus tseem ceeb.
Txhua hnub ntawm - qhov chaw tshawb xyuas ceev cov ntsiab lus tseem ceeb ua ntej pib lub tshuab txhua hnub. Cov neeg ua haujlwm saib xyuas cov ntaub ntawv ntsuas kub ntawm txhua cheeb tsam ntawm tus tswj kub khiav ua ntej ntau lawm. Yog tias qhov kev nyeem ntawv dhia tsis tu ncua, qhov kub nce qeeb lossis TC lub tswb tsis raug tshwm sim, kos rau thaj tsam thermocouple thiab npaj kev saib xyuas tom qab kaw. Saib xyuas seb cov hlau braided sab nraud ntawm lub thermocouple puas muaj extrusion deformation, tawg thiab ntog shielding mesh, seb lub connector davhlau ya nyob twg muaj siab - kub scorch marks, thiab cuam tshuam nrog txawv txawv xaim nyob rau hauv lub sij hawm kom tsis txhob raug kaw thaum lub sij hawm tsim khoom. Tom qab txhua lub pwm qhib, saib seb cov hlau puas raug rub thiab ncab los ntawm cov pwm phaj, kho cov hlau kho cov hlua khi kom ruaj khov txaus bending margin.
Lub hli me me disassembly thiab kev saib xyuas kev ua haujlwm tshwj xeeb. Tom qab cov khoom tsim tawm txhua hli tiav, kaw thiab txias qhov kub khiav mus rau hauv chav tsev kub, disassemble tag nrho cov thermocouple connectors ib tug los ntawm ib tug, so lub davhlau ya nyob twg hlau hu nrog cawv paj rwb ntaub kom tshem tawm siab - kub oxide txheej thiab cov plua plav yas, re-tighten lub davhlau ya nyob twg kho screws kom tsis txhob muaj kev sib cuag los ntawm kev vibration. Tshawb xyuas txoj haujlwm dabtsi yog khoov ntawm cov ntxhia insulated sheath rau cov kab nrib pleb, thiab hloov lub sensor nrog sheath puas tsuaj ua ntej kom tsis txhob qhib qhov hluav taws xob tam sim ntawd hauv cov txheej txheem tsim khoom. Cais tawm cov thermocouple hlau routing dua, cais cov teeb liab hlau thiab cua sov fais fab hlau kom tshem tawm electromagnetic cuam tshuam crosstalk.
Peb lub hlis twg sib sib zog nqus disassembly thiab ntxuav tu specifications. Txhua peb lub hlis, tshem tawm tag nrho cov nyees khawm manifold thermocouples thiab lub nplhaib caij nplooj ntoos hlav nozzle thermocouples, txhuam qhov ntsuas kev sib cuag nrog cov ntaub zoo abrasive kom tshem tawm cov carbonized yas deposits tsim tom qab ntev - cua sov. Hloov lub caij nplooj ntoos hlav ntsuas lub nplhaib nrog pom tseeb elastic attenuation, ntxuav lub manifold mounting dav hlau, rov thov siab - kub thermal conductive muab tshuaj txhuam thaum lub sij hawm reinstallation, thiab zawm lub compression screws raws li tus qauv torque tus nqi. Siv ib lub ntsuas ntsuas los ntsuas qhov txuas ntxiv thiab kev tiv thaiv kev tiv thaiv ntawm txhua lub thermocouple, tshuaj xyuas cov sensors nrog cov xaim hluav taws xob ntau ntxiv thiab muaj peev xwm tawg zais zais kev phom sij rau kev hloov pauv, thiab zam cov khoom tsis zoo uas tshwm sim los ntawm cov teeb liab drift hauv lub quarter tom ntej.
Kev tshuaj xyuas kev ua tau zoo txhua xyoo thiab batch hloov kev npaj. Tom qab ib xyoos ntawm kev siv tas mus li, tag nrho cov thermocouples ntawm cov pwm yuav tsum tau ua tiav qhov ntsuas kub thiab ntsuas qhov ntsuas qhov tseeb. Muab tag nrho cov sensors rau ntawm qhov ntsuas kub tsis tu ncua kom ntsuas qhov ntsuas kub kom sib piv qhov ntsuas kub nyeem ntawv yuam kev nrog tus qauv ntsuas ntsuas thermocouple. Cov sensors nrog kev ua yuam kev tshaj lub Hoobkas kam rau ua qauv yog hloov nyob rau hauv batch kom tshem tawm kev laus tsis ua hauj lwm zais kev phom sij. Rau cov pwm nrog 24-teev yam tsis muaj kev cuam tshuam loj ntau lawm txhua xyoo puag ncig, ua ntej lub voj voog hloov pauv mus rau 8 lub hlis, vim tias ntev - lub sijhawm ua haujlwm kub kub tsis tu ncua yuav ua rau kom qaug zog ntawm cov hlau hlau thiab cov qauv sib txuas.
Ntev - lub sij hawm cia tu specifications ntawm spare qhov chaw thermocouples. Cov thermocouples seem uas khaws cia rau hauv lub rhiav yuav tsum tau muab tso rau hauv ib qho chaw qhuav qhov kub thiab txias cia lub thawv, tsis txhob muab cov khoom hnyav los nyem lub plhaub, thiab tsis txhob rov khoov qhov ntsuas qhov ntsuas qhov ntev ntev. Muab faib thiab khij K-hom thiab J- hom sensors cais, thiab sau cov ntaub ntawv ntev thiab cov xov xov tshwj xeeb ntawm daim ntawv khaws cia kom tsis txhob muaj qhov tsis sib xws thaum hloov pauv xwm ceev. Ua ntej txhim kho cov thermocouple seem ntawm cov pwm, ua ib qho kev sim luv luv kom paub meej tias tsis muaj cov xaim tawg thaum khaws cia thiab kev thauj mus los.
Formulating ib tug ruaj thermocouple tswj txoj kev npaj thiab siv raws li nruj raws li lub voj voog yuav txo tau cov thermocouple tsis ua hauj lwm tus nqi los ntawm ntau tshaj 75%, zoo zam tsis txhob xav tias pwm kaw poob los ntawm sensor faults, stabilize lub melt kub tshuav nyiaj li cas ntawm lub kub khiav system, thiab txo cov khoom puas ntawm txhaj molding ntau lawm kab los ntawm qhov chaw.
