Yuav ua li cas mus saib hauv lub nrog sensor? Hall Sensor - duab, nqe, hloov

Nyob rau hauv no tsab xov xwm koj yuav kawm tau li cas mus saib hauv lub Hall sensor, uas yog siv nyob rau hauv lub tsheb Vaz 2108 thiab newer. Koj to taub tias ib lub tsheb uas tsim nyog los tswj tag nrho cov ciaj ciam ntawm lub internal combustion engine, nyob rau hauv thiaj li yuav paub tias, nws yog nyob rau hauv dab tsi mob. Cov xws li ib tug yuav cais tawm lub Hall sensor, uas yog ntsia tau rau tag nrho cov tsheb txawm peem rau nrog ib tug contactless ignition system. Nrog rau qhov no ntaus ntawv muab tawm kom tau tshem ntawm cov kev sib cuag breaker, thiab ib txhij ua rau kom cov zis voltage ntawm lub kauj, muaj zog, uas yog tsim nyob rau ntawm lub txim electrodes.

sensor ua hauj lwm

Nyob rau hauv lub Hall sensor voltage hloov tshwm sim nyob rau hauv cov kev tswj tso zis thaum lub sij hawm hloov magnetic teb. Qhov no ntaus ntawv yog heev txhim khu kev qha, yuav tsum tau tsis muaj kev pab los ntawm tus neeg tsav tsheb thaum lub sij hawm tag nrho lub sij hawm ntawm lub lag luam. Nyob rau tsheb nrog carburetor txhaj system xws sensors yog mounted nyob rau hauv lub ignition distributor. Yog hais tias muaj yog ib tug tsis ua hauj lwm ntawm nws, lub txim yog tsis ua. Li ntawd, cov cav yuav tsis tau pib. Nyob rau Vaz 2108 Hall sensor yog ib tug loj lub caij ntawm lub ignition system. Nyob rau txhaj tsheb kuj siv los ntawm sensors, uas yog raws li nyob rau hauv lub Hall nyhuv.

Neej puas: dab tsi yuav?

Nyob rau hauv cov ntaub ntawv no, tsis ua hauj lwm ntawm tsuas yog ib sensor yooj yim muaj peev xwm cheem lub engine. Hall-nyhuv switching hu ua, raws li tau zoo raws li kev ntseeg, kev ceev kom paub tias. Nrog nws, tam sim no hais kom ua Pib ntsais koj teeb kis tau. Nyob rau hauv nws nyuaj daim ntawv, qhov no sensor yog analog converter, nws yuav ua tau ib switching fais fab mov nyob rau hauv lub tsheb tiv cav tseb. Kuj siv ib co sensors kev khiav hauj lwm nyob rau hauv tus ntawm mus tas li cov hlau nplaum. Ib yam li ntawd Vaz 2108 sau rau lub Hall sensor.

Tus tsim ntawm lub ntaus ntawv

Feem ntau cov Hall sensor yog nyob rau hauv ib lub cev nrog cov hlau tub ntxhais, thiab ib tus hlau nplaum. Nws tso cai rau koj mus cuam tshuam tus siv lead ua semiconductor. Nyob rau txhua lub tsheb cov sensors khiav lag luam tsuas nrog kev tswj tswvyim. Nrog nws tshwm sim hauj lwm ntawm lub ntaus ntawv nyob rau hauv lub hom ntawm kev tiv thaiv. Nws puv rau hauv thiab tawm ib tug tswb. Nws yog ib nqi sau cia hais tias Hall nyhuv sensors yog feem ntau siv nyob rau hauv kev lag luam. Nyob rau hauv kev, pneumatic pab kiag li lawm, computerized drives keb soj ntsuam. Nyob rau hauv tas li ntawd, feem ntau ntawm contactless ignition systems raws li nyob rau hauv lub chaw ua hauj lwm ntawm no xyov ntaus ntawv. Tsis tas li ntawd nyob rau hauv computer technology nws yog heev kom nrhiav tau li ntawd hauj lwm rau lub Hall nyhuv. Nyob rau hauv kev, lawv yog ntsia tau rau hauv lub joysticks thiab cov twj remote controls. Nws yog ib nqi sau cia hais tias muaj yog ib tug txawv tus nqi ntawm lub Hall sensor. Tus nqi ntawm no ntaus ntawv rau kev siv nyob rau hauv ib tug Vaz tsheb ignition system - txog 200 rubles.

Qhov zoo ntawm kev siv

Los ntawm kev siv cov cuab-nyhuv sensor yuav tau txais ib tug zoo heev. Nyob rau hauv kev, nws yuav yooj yim heev nqa ib speedometer los yog tachometer Circuit Court microcontroller. Nyob rau hauv tsheb daim ntawv sau npe siv nws puv ho zoo qhov tsis muaj tus nrog combustion engine. Thiaj li, thauj nyab xeeb yog muaj zog muaj nuj nqis. Feem ntau, cov sensors saib xyuas cov kev ceev ntawm kev sib hloov ntawm lub camshaft, crankshaft, muab ib tug ceev heev pib-up ntawm lub cav. Thiab kuj nrog kev pab los ntawm kev ua hauj lwm tachometer. Lub sensor yog tas tam sim no nyob rau hauv lub tsim ntawm anti-lock systems. Nyob rau hauv ib co motors ua hauj lwm nrog lub hwj chim los ntawm DC tam sim no sensor ntawm lub Hall yog siv los mus txiav txim qhov chaw ntawm lub rotor. Nws yog ib nqi sau cia hais tias electronics kho tau zoo heev nyuab, yog tias koj nruab ib lub sensor nrog sib txawv tsis.

Main ntsiab ntawm lub ntaus ntawv

Koj yuav tsum nrhiav tau tawm yog dab tsi tsim los ntawm tus Hall sensor nyob rau hauv thiaj li yuav to taub yuav ua li cas nws ua hauj lwm. Tus tsim yog yooj yim heev, tab sis nws yog nyob ntawm dab tsi zoo ntawm daim ntawv thov ntawm cov hluav taws xob ntaus ntawv nyob rau hauv lub tsheb. Cov sensors muaj ib tug heev los ntawm cov compound rau ib tug semiconductor nti. Nyob rau hauv kev, nws yog feem ntau siv xws li ib tug tshuaj raws li indium. Qhov no semiconductor yog mounted rau ib tug substrate ua los ntawm txhuas thiab yog mounted nyob rau hauv cov ua hauj lwm feem ntawm lub caij. Crystal dav hlau thiab lub sensor nyob perpendicularly rau txhua lwm yam. Los ntawm tus siv lead ua feem yog conductors los ntawm kev uas txuas mus rau ib qho hluav taws xob Circuit Court. Ua ntej koj yuav mus saib lub Hall sensor, nws yog tsim nyog los tig nws tawm. Crystal semiconductor yog nyob ze ntawm lub hlau nplaum. Thiab cov kab kawg ntawm kev quab yuam yog ntawm lub kaum sab xis ntawm 90 degrees. Thaum zoo li no tshwm sim nyob rau hauv lub siv lead ua runningaway EMF. Nws yog ib nqi sau cia hais tias lub sij hawm ntawd, raws li cov Hall nyhuv. Nws tshwm sim nyob rau ib lub sij hawm thaum tus neeg xyuas pib kis tau los ntawm ib tug sib nqus teb. Nyob rau tib lub sij hawm hloov nws kev taw qhia txog lub magnetic teb kuj nyob rau semiconductor nti.

mob sensor

Thiab tam sim no nws yog los tham txog yuav ua li cas cov tshev mis ib tug ntaus ntawv xws li ib tug Hall sensor. Cov duab no unit yog muab nyob rau hauv tsab xov xwm. Nws tseem yog tsim nyog los hais txog lub ntsiab tsos mob uas manifest lawv tus kheej thaum lub sij hawm breakage ntawm lub fais ntaus ntawv. Mus nqa tawm diagnostic ua hauj lwm koj yuav tsum muaj ib tug multimeter. Nws yog tsim nyog los txhais nws rau hauv ib tug voltage ntsuas hom. Nyob rau hauv no ntau lub measured voltage yuav tsum 12 volts. Multimeter zoo davhlau ya nyob twg txuas mus rau lub teeb liab hlau. Tsis zoo - ntawm tag nrho cov. Yog hais tias tus ntaus ntawv yog tsis ua hauj lwm kom zoo, nws cov tsoom fwv yog dab tsi, lub voltmeter yuav sib txawv nyob rau hauv ntau 0,4..3 Volt. Yog hais tias lub sensor yog cov, nws yuav tsum tau hloov rau cov tib yam. Yog hais tias koj tsis muaj ib tug multimeter, tab sis muaj ib tug xav mus xyuas lub Hall sensor, nws yog tsim nyog los hloov nws ib tug tshiab lub caij, uas yog lub npe hu mus ua hauj lwm. Nws yuav ua tau yooj yim npaum li, txawm li cas los, kim kim, raws li cov nqi ntawm no caij rau ib co tsheb yuav ua tau loj. Ntawm no yog yuav ua li cas mus saib hauv lub Hall sensor, txoj kev yuav ua tau ib tug ob peb.

Ua hloov

Los hloov qhov Hall sensor rau lub timer, koj yuav tsum disconnect tus cover. Nyob rau classic series lub tsheb rau no ob latches ntsia. Yog hais tias peb yuav sib tham txog rau pem hauv ntej-log tsav tsheb Vaz, lub hau yuav tsum tau muab tshem tawm los ntawm unscrewing lub ob bolts. Tom ntej no, kos tus cim rau txoj hauj lwm ntawm lub slider rau tom qab nqa tawm lub haum ntawm tiv cav tseb. Tom qab hais tias, ib tug series ntawm classic tsheb tramblor muab tshem tawm kiag li. No tau txais cov ntsiab noob txiv rau "13". Nyob rau hauv pem hauv ntej-log tsav tsheb yuav tsum tseem ceeb nyob rau hauv lub "10" rau unscrew peb ceev. Tsis txhob hnov qab kom tshem tau ntawm lub hose uas mus rau hauv lub tshuab nqus mus rau lub proofreader. Ib tug rauj yog tsim nyog los ua knock-tawm pin. Nrog rau qhov no mount ua clutch roj Reflector. Tam sim no, yuav ua li cas yog hloov Hall sensor.

Tshem cov sensor tramblera

Tom qab ntawd, tshuab ntxhua thiab lub tes tsho yog tshem tawm, thiab tramblora rotor tau tawm ntawm lub vaj tse. Ces, bolts yog rhuav los ntawm dag, uas yog tsau Hall sensor tsev nyob rau hauv lub rooj noj phaj. Nws tseem yog tsim nyog los tshem tawm cov hlau haum thiab ib lub tshuab nqus regulator. Nws yog ib nqi sau cia hais tias lub tom kawg yuav tau kiag li rhuav, thiab tsuas yog ib tug me ntsis rub mus rau sab los tso saib cov muaj chaw seem. Nyob rau hauv pem hauv ntej-log tsav tsheb ua hauj lwm yog ua li cas yooj yim dua. Muab tshem tawm los ntawm lub latch slider vaj tse, tom qab uas lub ntaub thaiv npog yog muab tshem tawm. Nrog ib tug ntswj ntsia hlau unscrew mount Hall sensor. Raws li zoo li ib tug me me ntsia hlau uas yog kho cov plug rau lub vaj tse tramblora. Ntawm no yog yuav ua li cas mus saib hauv lub Hall sensor thiab hloov nws. Cov ua hauj lwm tsis yog yooj yim, koj yuav lis ob peb feeb.
