Dab tsi yog qhov pheej hmoo zais ntawm kev rov siv dua thib ob - Tes Kub Kub Khiav Thermocouples
Tso lus
Txhawm rau txo tus nqi seem, ntau tus neeg tsim pwm yuav thib ob - tes disassembled thermocouples los ntawm cov pwm rov ua lag luam, tsis quav ntsej txog qhov zais qhov kev laus puas tsuaj hauv cov khoom siv uas tsis tuaj yeem tshawb pom los ntawm kev tshuaj xyuas yooj yim. Kev rov siv dua thib ob - tes thermocouples ua rau muaj qhov tsis txaus ntseeg tsis tu ncua, nquag kaw tsis tu ncua thiab txawm tias muaj kev puas tsuaj rau cov khoom siv kub kub, qhov poob tag nrho yog ntau dua li qhov kev txuag me me ntawm cov nqi yuav khoom. Hauv tsab xov xwm no muaj ntau qhov kev txhawj xeeb zais ntawm cov thermocouples rov qab siv dua tau teev tseg thiab cov qauv tshuaj ntsuam tau muab rau hauv cov qauv qauv rau kev siv ib ntus ntawm ob- tes sensors.
Qhov pom tseeb tshaj plaws zais kev phom sij yog irreversible aging ntawm alloy hlau thiab cumulative drift ntawm kub. Lub sij hawm ntev ua haujlwm kub kub ntawm cov pwm qub tau ua rau cov hlau siv lead ua hloov pauv thiab oxidation thiab ruaj khov sib txawv ntawm cov xov hlau sab hauv ntawm ob- tes thermocouples, uas tsis tuaj yeem zam los ntawm kev ntxuav ntawm qhov chaw thiab cov maub los offset calibration. Txawm tias qhov zoo li tsis pom tseeb, qhov ntsuas kub tsis raug yog feem ntau ntau dua ± 2℃tom qab kev teeb tsa ntawm cov neeg ua haujlwm kub tshiab, cov yas hlawv, cov khoom txias thiab cov khoom tsis sib xws yuav tshwm sim hauv cov khoom loj. Lub siab -kub N- hom thermocouples siv rau PPS thiab LCP molding muaj kev laus ntau dua, thiab lawv cov kev tiv thaiv kev ua haujlwm drift poob qis tom qab 6 lub hlis ntawm kev pabcuam. Thib ob-cov khoom siv tes yeej poob qhov muaj peev xwm sib piv rau siab -kub engineering yas pwm.
Hidden sheath micro-corrosion perforations ua rau luv luv-circuit thiab qhib- teeb meem hauv Circuit Court. Feem ntau thib ob - tes thermocouples yog dismantled los ntawm pwm tsim hluav taws xob - retardant, recyclable los yog halogen- muaj caustic polymers. Acid-cov pa roj uas tsis muaj hluav taws xob ua rau pom tsis pom micro-pitting qhov ntawm lub plhaub, uas tsis tuaj yeem pom ntawm qhov muag liab qab. Tom qab reinstallation thiab cua sov, lub sheath yog infiltrated los ntawm rhiav ya raws thiab yas vapor los ntawm lub qhov me me, uas degrades cov magnesium oxide rwb thaiv tsev hmoov nyob rau hauv 1-2 lub lis piam thiab ua rau random luv luv - tswb Circuit Court. Cov teeb meem luv luv -circuit teeb meem ua rau cov zis ntawm cov cua sov coil ua kom lub zog tag nrho txhua lub sijhawm, uas ua rau cov khoom siv nozzles thiab cov cua kub hauv zos overheating carbonization ntawm cov manifold, uas yuav hlawv tawm cov cua kub kub thiab ua rau cov kub khiav hlau substrates.
Kev tu tsis tuaj yeem kho qhov qaug zog puas tsuaj rau cov qauv sab hauv. Lub zog elasticity ntawm compression springs ntawm thib ob- tes tiaj tus- lub taub hau thiab khawm thermocouples ploj tom qab ntau txhiab zaus ntawm thermal expansion thiab contraction, xws li cov thermocouples tsis tuaj yeem tswj xyuas nruj ntawm qhov ntsuas lub taub hau thiab kub khiav, thiab qhov kub thiab txias nyeem ntawv tsis ruaj khov. Cov hlau hluav taws xob sealing kua nplaum muaj hnub nyoog thiab sib cais, poob noo noo thiab corrosion kuj muaj nuj nqi; cov armored dabtsi yog khoov seem ua rau sab hauv alloy hlau qaug zog fractures undetectable sab nraum, uas tawg kiag li tom qab kaum ob ntawm pwm qhib mus. Lub davhlau ya nyob twg ntsaws pins tau ntsaws rau hauv thiab tawm rau lub sijhawm ntev, thiab txheej txheej tuab ntawm oxide xeb tau tsim, uas ua rau muaj kev tiv thaiv kev tiv thaiv thiab ua rau lub teeb liab txo qis. Cov kev qaug zog sab hauv no tsis tuaj yeem kho los ntawm kev ntxuav lossis lubrication. Txoj kev daws tsuas yog hloov pauv tag nrho.
Tsis paub sib xyaw ua haujlwm keeb kwm qhia txog kev phom sij ntawm cov khoom siv tsis sib xws. Kev ua cov yas muaj pes tsawg leeg thiab thawj daim ntawv thov pwm ntawm rov ua dua thib ob - tes thermocouples feem ntau tsis tuaj yeem tshawb pom. Lub sensor pib siv rau corrosive PVC molding tuaj yeem siv rau kev kho mob pob tshab PC kub khiav; cov khoom seem corrosive nyob rau hauv lub sheath yuav tsis tu ncua volatize thiab pollute kev kho mob-qib yaj, uas yuav ua rau cov khoom biocompatibility txaus ntshai thiab batch rejection neeg thov. Thib ob- tes thermocouples uas tsis paub hom xaim tuaj yeem ua ke K-hom thiab N- hom hlau hlau thiab ua rau muaj qhov kub thiab txias nyeem offset tom qab txuas rau cov tswj tsis sib xws.
Yog tias cov tuam txhab raug yuam kom siv thib ob - tes thermocouples rau ib ntus qis - ntim cov pwm sim, vim tsis muaj nqi, kev tshuaj xyuas ntau yam yuav tsum tau ua. Ua ntej ua cov tshuaj pleev ib ce kom tsis lees paub cov khoom uas muaj lub tes tsho sab nrauv, rusty plugs thiab pitted sheaths. Thib ob, nqa tawm multimeter kuj thiab rwb thaiv tsev ntsuas los lim tawm cov sensors nrog aberrant voj tsis kam. Thib peb, peb- taw tes siab- ntsuas kub yog ua los ntawm lub tshuab ziab khaub ncaws qhuav thiab cov thermocouples nrog drift deviation ntau dua ± 1.2℃raug tso tseg. Plaub, txwv tsis pub lub voj voog kev pabcuam tsis pub ntau tshaj ob lub lis piam thiab txwv tsis pub siv cov tsheb, kev kho mob thiab hluav taws xob precision pwm.
Los ntawm qhov ntev - lub sij hawm tsim cov nqi ntawm qhov pom, hom- tshiab calibrated thermocouples nrog unambiguous zoo traceability yuav zam tau cov khoom tsis zoo thiab cov khoom siv tu cov nuj nqis vim yog qhov tsis zoo ntawm qhov tsis zoo thib ob - tes sensors, uas yog tus nqi ntau dua - siv tau zoo ruaj khov.
