Qhov tsis pom kev txaus ntshai: tus neeg ua txhaum tom qab ntsuas qhov ntsuas kub tsis raug - xoob xaim.

Nyob rau hauv lub complex ib puag ncig ntawm industrial ntau lawm, qhov tseeb ntawm qhov ntsuas kub ncaj qha cuam tshuam cov khoom zoo, kev ruaj ntseg ntau lawm, thiab kev lag luam efficiency. Ntawm ntau yam uas ua rau muaj qhov txawv txav ntawm qhov ntsuas kub, xoob xaim lossis kev sib cuag tsis zoo yog ib qho teeb meem tshwm sim thiab yooj yim overlooked. Niaj hnub no, peb yuav delve rau hauv kev cuam tshuam mechanism ntawm no "invisible killer" thiab nws countermeasures.

I. Yuav ua li cas Loose Wiring cuam tshuam nrog kev ntsuas kub

Thaum xaim xoob lossis muaj kev sib cuag tsis zoo, nws thawj zaug ua rau muaj qhov nce ntxiv ntawm qhov ntsuas qhov ntsuas. Pt100 platinum tiv thaiv tus pas ntsuas kub muaj qhov tsis kam ntawm 100Ω ntawm 0 degree, thiab qhov tsis kam nce los ntawm tsuas yog 0.385Ω rau txhua 1℃qhov kub thiab txias. Qhov no txhais tau hais tias txawm tias ib qho ntxiv 1Ω ntawm kev tiv thaiv kev tiv thaiv tuaj yeem ua rau qhov ntsuas kub tau kwv yees li 2.6℃siab dua li qhov xav tau.

Nyob rau hauv qhov tseeb muaj ib puag ncig, vim kev co, thermal expansion thiab contraction, thiab lwm yam, xoob xaim tuaj yeem ua rau tus nqi ntawm qhov ntsuas Circuit Court tsis ruaj khov, ua rau kub hloov pauv lossis dhia. Ntawm cov duab sib txawv, qhov kub thiab txias yuav qhia ntau "khib nyiab" es tsis txhob muaj qhov nkhaus.

Qhov tseeb dua, thaum qhov kev sib txuas xoob tag nrho ua rau muaj kev sib txuas tsis zoo lossis qhib Circuit Court, DCS lub vijtsam tuaj yeem tso saib "tuag pixel" lossis "infinite," ua rau muaj kev txiav txim siab tsis zoo hauv kev tswj hwm thiab txawm tias cov khoom siv tsis raug.

II. Deeper Hazards of Loose Wiring

Kev Nyab Xeeb Kev Nyab Xeeb: Kev tiv thaiv ntau ntxiv ntawm qhov xoob tuaj yeem ua rau muaj cua sov hauv cheeb tsam nyob rau hauv cov xwm txheej muaj zog. Cov kev ntsuam xyuas qhia tau hais tias thaum qhov kev tiv thaiv tiv thaiv ntau tshaj 5Ω, qhov kub hauv zos tuaj yeem ncav cuag tshaj 150℃tom qab ib teev ntawm kev siv zog, yooj yim ua rau junction box carbonization lossis hluav taws kub.

Kev pheej hmoo ntau lawm: Ib tsob nroj tshuaj tau ntsib txoj kab ntau lawm los ntawm kev tswj xyuas vim qhov tawg ntawm C-theem hlau nyob rau hauv lub thermal resistor, thaum kawg ua rau ib lab-unit ntau lawm nres. Qhov tseeb dua, yog tias qhov ntsuas kub ntsuas ntsuas cuam tshuam nrog kev tiv thaiv kev cuam tshuam, nws tuaj yeem ua rau lub kaw lus tsis raug kaw, ua rau poob nyiaj txiag loj.

Data Distortion: Kev sib cuag tsis zoo tuaj yeem ua rau Pt100 hloov pauv ntawm peb -hlau thiab ob- xov hlau, thiab ob-kab hlau tsis tuaj yeem tshem tawm cov kev cuam tshuam ntawm cov hlau lead hauv kev ntsuas. Qee qhov xwm txheej, qhov no tuaj yeem ua rau qhov ntsuas qhov sib txawv ntawm ze li 20 degree, cuam tshuam rau qhov tseeb ntawm kev tswj cov txheej txheem.

III. Kev tshuaj xyuas qhov ua rau xoob xaim

Ib puag ncig kev vibration: Hauv cov chaw vibrating xws li kiv cua thiab cov twj tso kua mis, loosening ntawm screws tom qab lub sijhawm ua haujlwm ntev - yog ib qho tshwm sim. Cov ntaub ntawv qhia tau hais tias qhov tsis ua hauj lwm tus nqi vim kev sib txuas xoob nce ntau dua 60% hauv qhov chaw vibrating.

Thermal Expansion and Contraction: Kub hloov ua rau rov nthuav dav thiab cog lus ntawm cov hlau hlau thiab cov terminals, maj mam loosening cov ntsiab lus txuas.

Oxidation thiab Corrosion: Nyob rau hauv siab - kub thiab siab - cov av noo ib puag ncig, terminals yog nquag oxidation, thiab txawm kho cov ntsia hlau tuaj yeem xeb thiab poob, ua rau muaj kev sib cuag tsis zoo.

Kev txhim kho tsis raug: Kev ua tsis tiav ntawm lub zog uas tau teev tseg lossis siv cov tshuab ntxhua khaub ncaws tsis zoo thaum lub sijhawm teeb tsa kuj tuaj yeem tsim teeb meem zais rau yav tom ntej loosening.

IV. Kev Tiv Thaiv thiab Kev Kho Mob

Cov tswv yim tiv thaiv:

Precise Installation: Siv lub ntsuas ntsuas ntsuas kom nruj cov terminals rau lub zog tshwj xeeb (0.5-0.8 N·m) thiab kos nrog xim liab rau kev tshuaj xyuas tom qab.

Kev vibration-Proof Design: Nruab silicone damping pads nyob rau hauv vibrating cheeb tsam thiab muab ib tug tsis khoov khoov rau hauv lub cable (lub vojvoog> 5 npaug ntawm cov hlau txoj kab uas hla).

Kev tshuaj xyuas tsis tu ncua: Kev tshuaj xyuas txhua hli ntawm lub thawv hlws ris rau cov cim ntawm oxidation thiab ntsia hlau cim; Peb lub hlis twg infrared scanning ntawm hlws ris lub thawv kub.

Kev Tiv Thaiv Ib puag ncig: Hauv qhov chaw ntub dej, siv ob lub foob ntawm silicone sealing nplhaib + waterproof sealant; nyob rau hauv siab-qhov kub thiab txias, nruab ib lub tshav kub-dissipating txhuas lub tes tsho.

Kev daws teeb meem:

Kev Tiv Thaiv Kev Nyab Xeeb: Tau txais daim pib txij nkawm, tshem tawm kev tiv thaiv kev cuam tshuam, thiab tiv thaiv kev ua haujlwm tsis zoo.

Fais fab kev pov thawj: Disconnect lub teeb liab Circuit Court fais fab mov; paub meej tias tsis muaj hluav taws xob nrog multimeter; kev ua neej nyob yog txwv tsis pub.

Kev soj ntsuam txheej: Tshem tawm cov oxide txheej, siv cov roj nplaum, thiab rov- zawm rau lub zog uas tau teev tseg.

Kev Ntsuam Xyuas Circuit Court: Siv lub thawv ua kom muaj zog los simulate cov tswv yim; qhov kev txheeb xyuas qhov yuam kev yuav tsum tsawg dua lossis sib npaug li 0.5%.

Hauv paus Kev Kho Kom Zoo: Txhim kho kev co damping brackets hauv thaj chaw kev co kom daws tau qhov teeb meem.

Technical Innovation Solution: Ib txoj hauv kev txhim kho kev xaim yog txuas rau ob txoj hauv kev uas muab nrog Pt100 rau tib lub davhlau ya nyob twg nyob rau hauv parallel. Qhov no ua kom ntseeg tau tias txawm tias ib qho kev sib koom ua ke tuaj yeem xoob, tus nqi tiv thaiv kab mob yuav tsis cuam tshuam rau qhov ntsuas kub tiag tiag, nrog qhov sib txawv ntawm qhov siab tshaj ntawm 1-2 degree. V. Kev daws teeb meem los ntawm Hequan Instrument Technology

Hais txog qhov mob ntawm kev lag luam ntawm cov xov hlau xoob, Hequan Instrument Technology tau tshaj tawm PT100 los tiv thaiv - vibration series, tshwj xeeb tshaj yog hais txog qhov tsis xws luag ntawm cov tsoos RTDs:

Triple-locking terminal structure: Siv triple-locking design of spring washers, toothed washers, and self-locknuts, it achieves zero loosening in a 50Hz/2mm amplitude vibration test, expanding products lifespan by 3 times.

Kev nyuaj siab thev naus laus zis: Ntxiv titanium alloy kev ntxhov siab rings rau cov armored terminals txo qhov kev pheej hmoo ntawm kev khoov qaug zog tawg los ntawm 70%.

Kev soj ntsuam kev ua haujlwm ntse: Lub cim tshiab ntawm RTDs sib koom ua ke IoT saib xyuas module, xa cov ntaub ntawv tiv tauj thiab ntsuas kub hauv lub sijhawm. Nws muab 7-hnub ua ntej ceeb toom ntawm kev pheej hmoo ntawm kev poob qis thiab tuaj yeem ua rau kev saib xyuas kev ua haujlwm ntawm PLC.
