Txij li thaum qhia lub micro hloov nyob rau xyoo 1930, qhov hloov hluav taws xob me me no tau tsim kho kom tsis tu ncua kom tau raws li ntau yam kev thov, suav nrog kev siv dav hlau, khoom siv hauv tsev, tswj kav dej, khoom siv kho mob, tshuab txaws, thiab kuaj. Cov cuab yeej siv, cov timers thiab cov vev xaib, thiab lwm yam.
Precision micro keyboards feem ntau muaj peb yam tshwj xeeb: hom pib, hom nrog ua haujlwm tuav, hom nrog ua haujlwm tuav thiab plhaub hom. Lub micro hloov adopts xovxwm thiab lub caij nplooj hlav tsim.
Txawm hais tias cov engineers tab tom nrhiav cov thermostats siv nyob rau hauv thaj chaw cua sov lossis kev tiv thaiv kev lag luam boiler, lossis cov qib kev hloov ua kua hauv cov roj tsheb loj, lawv yuav tsum xav txog tsib yam tseem ceeb: kev ntsuas sab nraud, qhov hluav taws xob (hluav taws xob / hluav taws xob), kev cia siab (siv tshuab / hluav taws xob lub neej), ib puag ncig cov khoom siv (qhov chaw muaj xwm txheej, qhov kub thiab txias) thiab ntawv pov thawj lub koom haum. Cov kauj ruam 5 hauv qab no tuaj yeem pab koj xaiv lub micro hloov haum rau koj daim ntawv thov tshwj xeeb.
Kauj Ruam 1: Nkag siab txog qhov loj me ntawm qhov hloov mus rau lwm yam ntxwv
Qhov loj me yog qhov tseem ceeb thaum xaiv lub micro hloov. Qhov loj ntawm lub pob hluav taws xob yog ncaj qha rau nws cov yam ntxwv, suav nrog cov thaj chaw tam sim no, kev mus ncig, thiab kev quab yuam ua haujlwm. Piv txwv, qhov hloov me me me tam sim no ntawm lub khw lag luam ntsuas 0.50 nti x 0.236 nti x 0.197 nti (LxWxH). Txawm hais tias lub pob hluav taws xob me me no tsim nyog rau kev kuaj pom lub xeev ntawm lub rooj sib txig sib txig sib luag, nws feem ntau tsuas tawg 0.1 mus rau 3 amperes (A) ntawm qhov tam sim no thiab mob stroke ntev.
Cov ntawv thov uas xav tau ntau dua tam sim no feem ntau yuav tsum muaj qhov hloov loj dua. Piv txwv li, hauv cov ntawv thov roj roj, lub micro hloov tau siv los xyuas txog qib ua kua yuav tsum muaj peev xwm muab peev xwm loj thiab tiv cov kab hluav taws xob loj. Feem ntau hauv kev siv qib ua kua hloov, lub pob hluav taws xob yuav tsum ncaj qha tsav lub taub dej thiab nqa lub qhov dej loj. Qhov no yuav tsum muaj lub micro hloov loj nrog qhov ntsuas tam sim no ntawm 20A lossis 25A ntawm qhov hluav taws xob ntawm 125VAC lossis 250VAC.
Ntsis: Qhov ntsuas me me hloov pauv, kab nrawm dua thiab tawg tam sim no uas tuaj yeem tawg.
Tsis tas li ntawd, qhov loj me ntawm hloov kuj tseem cuam tshuam rau lub zog ua haujlwm. Nyob rau hauv qhov xwm txheej zoo tshaj plaws, dab tsi cov engineers xav tau yog kev hloov nrog cov khiav hauj lwm qis thiab muaj peev xwm tam sim no. Tab sis qhov tseeb muaj qhov hais nruab nrab ntawm ob kis no. Txhawm rau kom muaj kev sib cuag zoo thaum muab cov dej loj tam sim no tiv thaiv ntau, lub pob hluav taws xob me xav tau lub caij nplooj ntoo hlav muaj zog, uas yuav ua rau muaj kev ua haujlwm ntau ntxiv thiab qhov loj ntawm lub pob hloov. Kev siv lub zog ua haujlwm tuaj yeem yog los ntawm 2 gram hauv cov ntawv tso pa pneumatic mus rau 8 ooj nyob rau hauv cov ntawv thov solenoid valve (xav tau ntau dua kev siv haujlwm). Qhov loj tshaj plaws hloov pauv ntawm lub lag luam yog 1.94 nti x 0.69 nti x 1.3 nti (LxWxH).
Cov kws tsim txuj ci yuav tsum xyuam xim rau qhov sib txawv ntawm kev mus los ntawm lub pob hluav taws xob - qhov kev ncua deb ntawm tus tes hloov mus' s txoj hauj lwm mus ncig thiab qhov chaw pib dua. Qhov pib txiav txim yuav sib txawv raws li cov ntawv thov sib txawv. Piv txwv li, hauv cov ntawv thov kub hloov pauv, qhov qhib / tawm haujlwm cov ntsiab lus yuav tsum yog ze li sai tau, thiab qhov sib txawv ntawm qhov sib txawv yuav tsum tsawg li 0.0001 nti. Txawm li cas los xij, nyob rau hauv kev thov ntawm cov kua qib kua, yog tias qhov sib txawv ntawm lub cev tsis ntev, nws yuav ua rau cov pleev pleev pib thiab nres ntau dhau, ua kom luv luv kev pab cuam lub neej ntawm lub twj tso kua mis.
Muaj peev xwm ua kom tau raws li qhov xav tau tshwj xeeb ntawm cov engineers.
Kauj ruam 2: Paub txog koj cov kev xav tau hluav taws xob
Lub tshuab hluav taws xob me me feem ntau tuaj yeem tsoo qhov tam sim no ntawm 5mA / 5VDC rau 25A / 250VAC. Lub micro hloov khoom kab muab cov khoom ntawm cov khoom siv los ntawm kev siv hluav taws xob tsawg mus rau lub zog thauj hluav taws xob hom, haum rau ntau yam kev siv.
Cov kws tsim choj yuav tsum paub txog cov ntsuas hluav taws xob tam sim no thiab qhov ntsuas hluav taws xob (AC lossis DC) uas xav tau rau ib daim ntawv thov tshwj xeeb txhawm rau txhawm rau xaiv qhov hloov chaw uas tsim nyog. Txij li ntau yam khoom siv hauv txhua qhov kev lag luam tau cog lus rau kev siv hluav taws xob tsawg, lub micro hloov mus yuav tsum muaj peev xwm ua haujlwm tau qis qis tam sim no (cav theem load) thiab DC voltage.
Txawm li cas los xij, tseem muaj qee qhov kev thov uas yuav tsum muaj cov kev hloov hluav taws xob uas muaj peev xwm txhawm rau loj cov kab hluav taws xob thiab qhov ntsuas hluav taws xob siab, xws li kev siv twj tso kua mis.
Ntxiv nrog rau qhov yuav tsum tau ntim, cov kws ua choj yuav tsum xaiv cov kev ncig uas tsim nyog. Tus hu mus sib txuas yuav tsum yog ib qho qhib (TSIS TAU) thiab ib txwm kaw (NC). Rau cov tsis muaj hom, feem ntau tsis muaj qhov tam sim no ntws los ntawm cov neeg. Thaum tus tes hloov lawm, txoj kev sib cuag raug kaw thiab lub voj voog txuas nrog. Rau NC-hom cov neeg, feem ntau tam sim no ntws ntawm cov neeg tiv tauj. Thaum tus tes hloov lawm, txoj kev sib cuag yuav qhib thiab lub tshuab hluav taws xob sib txuas.
Kauj ruam 3: Xav txog cov xwm txheej ib puag ncig
Ib puag ncig kev xav tau muaj qhov zoo rau kev xaiv ntawm lub chaw hloov me me, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov yuav tsum muaj kev ntseeg siab thiab qhov tseem ceeb xws li kev lag luam tswj thiab cov cuab yeej siv kho mob. Nkag siab txog thaj chaw puag ncig ntawm daim ntawv thov, nrog rau cov pa paug hauv huab cua uas tuaj yeem nkag mus rau tus tes hloov pauv, cov kua uas lub pob hloov mus rau, thiab kev ua haujlwm kub yuav tsum tau ua.
Rau cov ntawv thov nyob rau hauv ib puag ncig ib puag ncig hnyav, koj yuav tsum xaiv lub pob hluav taws xob kaw nrog lub dav kub ua haujlwm. Lub micro hloov hluav taws xob zoo tuaj yeem ua haujlwm nyob rau qhov kub thiab txias ntawm -65 degrees Fahrenheit (-54 degrees Celsius) txog 350 degrees Fahrenheit (177 degrees Celsius), uas tuaj yeem tiv nrog ntau cov ntawv thov. Nyob rau tib lub sijhawm, nws yuav tsum raug sau tseg tias qib tiv thaiv ntawm tus tes hloov yuav tsum yog tsawg IP67 txhawm rau tiv thaiv kua nkag mus. Qhov no tshem tawm qhov kev xav tau los siv sijhawm ntau ntawm cov qauv tsim ib puag ncig uas tuaj yeem ua tiav tib theem kev tiv thaiv.
Kauj ruam 4: Qhia meej txog lub neej ua haujlwm xav tau
Txoj kev ntseeg tau ntawm tus hloov yog qhov tseem ceeb. Koj yuav tsum qhia meej pes tsawg lub zog ntawm kev siv hluav taws xob thiab lub tshuab ua haujlwm raug rau ib daim ntawv thov? Cov keyboards sib txawv nyias muaj nyias cov khoom sib cuag, cov tsev nyob thiab cov davhlau ya nyob twg, uas tuaj yeem ua tau raws li hluav taws xob thiab kev ua neej nyob ntawm kev thov sib txawv.
Lub tshuab hluav taws xob muaj txiaj ntsig zoo tuaj yeem ua haujlwm 10 mus rau 20 lab lub sijhawm ua ntej cov cuab yeej tsis ua haujlwm, thiab tuaj yeem ua haujlwm 50,000 txog 100,000 zaug nyob rau hauv qhov siab tshaj plaws ua ntej hluav taws xob tsis ua haujlwm.
Raws li rau tus nqi me ntsis sib txawv ntawm cov ntawv sib txawv zoo, koj yuav tsum xav txog tag nrho cov nqi ntawm kev siv. Vim tias koj tsis yog tsuas yog them rau tus tes hloov pauv, tab sis kuj xyuas kom lub pob hloov mus ntev ntev yam tsis ua haujlwm. Feem ntau, tus nqi ntxiv ntawm kev siv lub pob hluav taws xob ntau dua yuav raug txo los ntawm nws tus nqi qis thaum lub sijhawm siv.
Kauj ruam 5: Kos rau qhov chaw ua haujlwm daim ntawv pov thawj xav tau
Xaiv lub pob hluav taws xob uas ua tau raws li ntau yam hluav taws xob thoob ntiaj teb tuaj yeem pab koj yooj yim cov khoom tsim rau cov cheeb tsam sib txawv. Qee cov ntawv pov thawj tseem ceeb suav nrog UL daim ntawv pov thawj hauv Tebchaws Meskas, cUL daim ntawv pov thawj lossis CSA daim ntawv pov thawj hauv Canada, ENEC daim ntawv pov thawj hauv Tebchaws Europe thiab CQC daim ntawv pov thawj hauv Suav teb, thiab KC daim ntawv pov thawj hauv Kaus Lim Qab Teb.
Thaum xaiv lub micro hloov, koj yuav tsum xav txog ntau yam, xws li qhov ntev, qhov yuav tsum tau ua haujlwm, qhov chaw ua haujlwm thiab kev ntseeg tau. Yog li no, koj yuav tsum to taub qhov thov siv tiag tiag: Kev hloov pauv yuav tsum muaj qhov loj me li cas? Dab tsi nyob qib zog yuav tsum tau? Puas yog nws lub siab thov? Tus tes hloov qhov yuav tsum tau kaw? Tus tes hloov qhov yuav tsum tiv taus huab kub? Puas yog nws xav tau lub koomhaum kev lees paub thoob ntiaj teb? Nws puas yog daim ntawv thov tseem ceeb? Thaum cov teeb meem no tau hais meej lawm, xaiv ib qho uas haum rau daim ntawv thov
