Cia peb xav txog hauv ib tsab xov xwm luv luv cov ntaub ntawv siv tau yooj yim ntawm cov cuab yeej nthuav dav uas ntsuas tus naj npawb ntawm kev hloov pauv, nws daim ntawv thov thiab kev ua haujlwm.

Tachometer: yog dab tsi?

Ntau lub tshuab ua haujlwm muaj qhov sib hloov. Nws yog ib qho tsim nyog yuav tsum paub txog qhov ceev uas lawv tig, seb nws zoo li cas, thiab lwm yam. Rau qhov no, ib qho cuab yeej tshwj xeeb hu ua tachometer tau tsim. Hauv qhov tseem ceeb, nws tso cai rau koj ntsuas qhov nrawm ntawm kev sib hloov, yog li koj tuaj yeem ua cov txheej txheem no txhawm rau tswj thiab kho yog tias tsim nyog.

Kev ua haujlwm ntawm lub tachometer feem ntau yog nthuav tawm hauv daim ntawv ntawm cov ntaub ntawv pom los ntawm cov duab digital lossis ntawm lub ntsuas ntsuas analog. Cov neeg feem coob uas tsis paub txog lo lus no feem ntau yuav pom nws hauv lawv lub tsheb. Txij li feem ntau lub dashboard ntawm lub tsheb yog muab nrog ib tug tachometer xwb.

Los ntawm txoj kev, lo lus no txhais los ntawm Greek li "kev ntsuas ceev". Thiab txawm hais tias tam sim no hauv tsheb cov cuab yeej tseem ceeb rau kev ntsuas qhov nrawm yog lub ntsuas ntsuas, txawm li cas los xij, lub tachometer ruaj ntseg txuas ntxiv mus nrog thawj tus ntawm lub vaj huam sib luag ntawm yuav luag txhua lub tsheb niaj hnub.txhais tau tias, thaum ua lwm yam tseem ceeb.

Cov cuab yeej yooj yim tshaj plaws

Qhov yooj yim tshaj plaws tachometer Circuit Court yog banal counter ntawm tus naj npawb ntawm cov kiv puag ncig ntawm ib feem ntawm txhua qhov kev ua haujlwm. Nws tuaj yeem yog cov cuab yeej siv tshuab, turbine, ncej ntawm lub tshuab drilling, thiab lwm yam. Txawm li cas los xij, daim duab yooj yim tshaj plaws yuav pom tsuas yog tus naj npawb ntawm kev hloov pauv ntawm qhov no. Thiab twb nrog ib tug zoo stopwatch, koj muaj peev xwm xam qhov nruab nrab tus nqi ntawm kev sib hloov ceev rau lub sij hawm txiav txim siab.

Qhov yooj yim tshaj plaws tachometer circuit yog qhia hauv daim duab. Nws siv lub yees duab sensor uas tau txais lub teeb liab los ntawm lub stroboscope mounted ntawm lub cev muaj zog ncej. Cov ntaub ntawv tau txais nyob rau hauv txoj kev no los ntawm photosensitive transistor yog pub rau lub microcircuit, uas ces outputs lawv nyob rau hauv cov hom ntawm ib tug tshwj xeeb zaub.

Kev faib tawm

Kev sib cais yog qhov yooj yim tshaj plaws los ua raws li lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub cuab yeej nws tus kheej. Muaj ob peb ntawm lawv, cia peb xav txog cov feem ntau. Ua ntej, sib nqus induction. Ntawm no lub hauv paus ntsiab lus yog qhov induction ntawm ib tug eddy tam sim no nyob rau hauv ib tug hlau lub cev, qhov loj ntawm uas nyob ntawm qhov kev sib hloov ceev. Thib ob, hluav taws xob tachometers. Lawv siv qhov kev vam khom ntawm qhov tso zis voltage tsis nyob ntawm qhov kev sib hloov ceev. Thirdly, photovoltaic, qhov twg lub teeb flux yog modulated. Thaum kawg, capacitive tachometers siv qhov kev cia siab ntawm tus nqi no ntawm kev sib hloov ceev. Muaj lwm tus. Sim los teb cov lus nug yooj yim: "Tachometer: nws yog dab tsi?", Peb yuav tsis mus rau hauv lub hav zoov complex ntawm tag nrho cov cev nqaij daim tawv.cov hauv paus ntsiab lus uas tuaj yeem siv los ntsuas qhov nrawm nrawm ntawm lub cev rotating.

Auto

Nyob hauv kev lag luam tsheb, kev ntsuas tus naj npawb ntawm cov kiv puag ncig ntawm cov khoom tig tau nquag siv. Piv txwv li, lub angular tshaj tawm ntawm lub crankshaft yog ib qho tseem ceeb kom paub, vim hais tias tus neeg tsav tsheb yuav tsum tsis txhob tsav lub cav mus rau hauv lub overload hom, tshwj tsis yog, ntawm chav kawm, nws yog Schumacher nyob rau hauv lub Formula 1 khiav. Tsis tas li ntawd, kev paub txog thaum twg yuav nce los yog downshift yog qhov tseem ceeb heev, dua li ntawm kev nce lub cav lub neej.

Los ntawm txoj kev, thaum nws los txog rau kev sib tw, tachometer RPM tseem ceeb dua ntawm no. Txij li thaum, txawm hais tias lub cav ua haujlwm tas li nyob rau hauv hom huab, nws cov peev txheej yuav tsum tau tiv thaiv, txawm li cas los xij, nyob rau lub sijhawm sib txawv kiag li. Thiab ib zaug ntxiv, los ntawm kev paub thaum nws tsis lig dhau mus rau upshift. Txwv tsis pub, koj tuaj yeem tsis tuaj yeem mus txog qhov kawg, nyob rau sab nraud nrog lub cav kub lossis jammed.

Daim ntawv thov

Cov cuab yeej siv dav tshaj plaws no tseem nyob hauv kev tsim kho tshuab. Lub tachometer rau lub cev muaj zog yog siv thaum ntsuas qhov ceev ntawm lub crankshaft. Internal combustion engines ntawm feem ntau ntawm cov khoom thauj nyob rau hauv cov kev pab cuam ntawm cov txiv neej yog nruab nrog no pab kiag li lawm ntaus ntawv. Qhov no suav nrog, tau kawg, tsheb, nrog rau cov dav hlau, tsheb ciav hlau, tsheb laij teb, nkoj thiab lwm yam.

Lwm daim ntawv thov tseem ceeb rau tachometers yog tswjkev sib hloov ceev ntawm qhov chaw ntawm ntau lub tshuab thev naus laus zis, xws li cov cuab yeej siv tshuab, cov cuab yeej drilling, thiab lwm yam. Thaum kawg, qhov kawg thiab twb tau siv qee yam tsis ncaj qha ntawm cov khoom siv no yog suav cov lej ntawm cov pulses hauv cov txheej txheem kev siv tshuab conveyor. Piv txwv li, qee cov khoom siv raw lossis cov khoom siv tau txav mus los ntawm txoj kab, thiab koj yuav tsum paub ntau npaum li cas tau dhau mus thiab xav tau ntau npaum li cas. Nws kuj tseem tuaj yeem siv los tswj lub sijhawm ua haujlwm ntawm txhua yam khoom siv hauv hom kev khiav haujlwm lossis thaum lub sijhawm ntsuas kev ua haujlwm.

Analog lossis digital?

Teb cov lus nug: "Tachometer: nws yog dab tsi?", Peb tsis tau xav txog lwm qhov tseem ceeb. Kev sawv cev ntawm cov ntaub ntawv xa tawm los ntawm lub sensor ntawm lub cuab yeej mus rau lub chaw tswj hwm ntawm lub tsheb lossis ntawm cov zaub ntawm lub tshuab lossis lwm yam khoom siv thev naus laus zis uas nws tuaj yeem siv tau. Puas tau txij li thaum muaj hnub nyoog ntawm tachometer ntawm lub tsheb panels, cov ntsiab lus analog ntawm cov ntaub ntawv nthuav qhia tau raug siv. Tsawg kawg yog vim li cas yooj yim uas tsis muaj txoj hauv kev digital hauv lub sijhawm nyob deb. Thaj, yog li ntawd, nws yog qhov yooj yim dua rau tus neeg tsav tsheb ntawm lub tsheb niaj hnub pom ib qho xub qhia tias muaj pes tsawg lub kiv puag ncig nws lub cav muab tawm thiab deb npaum li cas nws mus rau thaj tsam liab. Nws paub thiab pom.

Lub hnub nyoog digital tau coj tachometers uas qhia cov lej ntawm kev hloov pauv ntawm cov qhab nia raws li qhov hloov pauv tas li. Qhov kev sawv cev no me ntsis cuam tshuam qhov kev nkag siab ntawm tus nqi tiag tiag ntawm tus lej ntawm kev hloov pauv. Qhov no yog aggravated los ntawm qhov tseeb hais tias cov ntaub ntawv nyob rau hauv lub digital block yog tas li hloov, nyob rau hauv sib piv rau cov xub.pointer, uas muab tus nqi nruab nrab uas hloov tau yooj yim dua. Yog li ntawd, lub tsheb tachometer feem ntau yog analog. Nws yog dab tsi, peb cia siab, peb tau tswj kom nkag siab los ntawm cov khoom sib txuas.

Xaiv cov lus nug los ntawm lub npe. Nyob rau hauv kev sib ntaus sib tua ntawm "analogue" tawm tsam "digital", tus qub yeej meej meej rau nruab nrab tsav tsheb uas tsis tas yuav tsum paub tus nqi ntawm tus naj npawb ntawm cov kiv puag ncig nrog qhov tseeb ntawm 100 rpm hauv txhua thib ob ntawm nws lub sijhawm tom qab lub log. Tab sis nrog ntau yam kev hloov kho, piv txwv li, cov khoom siv hluav taws xob, qhov "digit" ignition yog tawm ntawm kev sib tw, vim nws muab tus engineer rau qhov tseeb tsim nyog.

Zoo kawg

Tau nug cov lus nug hauv kab lus: "Tachometer: nws yog dab tsi?", Peb pom nws lub hom phiaj tseem ceeb, kev siv, qee cov hauv paus ntsiab lus ntawm kev ua haujlwm. Feem ntau, cov cuab yeej siv tsis yog tsuas yog siv tau xwb, tab sis tsuas yog tsim nyog rau kev ua haujlwm raug ntawm ntau yam kev siv tshuab siv cov khoom sib hloov.
