Mokhoa oa ho Lekola Sensor ea Holo ka Multimeter (Tataiso)
Tse ka hare
Ho felloa ke matla, lerata le leholo, le maikutlo a hore enjene e notletsoe ka tsela e itseng ke matšoao a hore mohlomong u sebetsana le molaoli ea shoeleng kapa li-sensors tsa crank tsa hall ka hare ho enjene ea hau.
Latela mehato ena ho leka sensor ea Hall effect ka multimeter.
Ntlha ea pele, beha DMM ho DC voltage (20 volts). Kopanya lead lead ea multimeter ho ea pele e ntšo ea sensor ea holo. Theminale e khubelu e tlameha ho hokela terata e khubelu e ntle ea sehlopha sa terata ea sensor ea Hall. U lokela ho fumana 'malo oa li-volts tse 13 ho DMM. Tsoela pele ho hlahloba tlhahiso ea lithapo tse ling.
Sensor ea Hall ke transducer e hlahisang matla a motlakase ho latela matla a khoheli. Sehloohong sena, u tla ithuta ho leka sensor ea Holo ka multimeter.
Ho etsahala'ng ha lisensara tsa Hall li hlōleha?
Ho hloleha ha li-sensor tsa Holo ho bolela hore molaoli (boto e fanang ka matla le ho laola enjene) ha e na tlhahisoleseling ea bohlokoa e hlokahalang ho hokahanya matla a enjene hantle. Enjene e tsamaisoa ke lithapo tse tharo (mehato). Mekhahlelo e meraro e hloka nako e nepahetseng kapa enjene e tla khomarela, e felloe ke matla 'me e etse molumo o tenang.
Na u belaela hore li-sensor tsa hau tsa Hall li na le phoso? U ka leka ka multimeter ka ho latela mehato ena e meraro.
1. Tlosa le ho hloekisa sensor
Mohato oa pele o kenyelletsa ho tlosa sensor ho cylinder block. Hlokomela litšila, tšepe le oli. Haeba e 'ngoe ea tsona e le teng, e tlose.
2. Sebaka sa sensor ea camshaft / crankshaft sensor
Lekola schematic ea enjene ho fumana sensor ea camshaft kapa sensor ea boemo ba crankshaft ka har'a module ea taolo ea elektroniki (ECM) kapa sensor ea camshaft. Ebe u ama ntlha e 'ngoe ea terata ea jumper ho terata ea pontšo le pheletsong e' ngoe ho ea ntlheng ea probe e ntle. Probe e mpe e tlameha ho ama sebaka se setle sa chassis. Ak'u nahane ka ho sebelisa jumper ea likoena ha u hokahanya letoto la teko e fosahetseng sebakeng sa chassis - ha ho hlokahala.
3. Matla a ho bala ho multimeter ea digital
Ebe u beha multimeter ea digital ho DC voltage (20 volts). Kopanya lead lead ea multimeter ho ea pele e ntšo ea sensor ea holo. Theminale e khubelu e tlameha ho hokela terata e khubelu e ntle ea sehlopha sa terata ea sensor ea Hall. U lokela ho fumana 'malo oa li-volts tse 13 ho DMM.
Tsoela pele ho hlahloba tlhahiso ea lithapo tse ling.
Ebe o kopanya terata e ntšo ea multimeter ho terata e ntšo ea mohala oa lithapo. Mohala o mofubelu oa multimeter o lokela ho ama terata e tala holim'a mohala oa mohala. Sheba hore na motlakase o bontša li-volts tse hlano kapa ho feta. Hlokomela hore motlakase o itšetlehile ka ho kenngoa ha potoloho 'me o ka fapana ho tloha mochine o mong ho ea ho o mong. Leha ho le joalo, e lokela ho ba kholo ho feta li-volts tsa zero haeba li-sensor tsa Holo li lokile.
Tsamaisa makenete butle likhutlong tse nepahetseng ho ea ka pele ho encoder. Sheba hore na ho etsahalang. Ha o ntse o atamela ho sensor, motlakase o lokela ho eketseha. Ha u ntse u tsamaea, motlakase o lokela ho fokotseha. Sensor ea hau ea crankshaft kapa likhokahano tsa eona li fosahetse haeba ho se na phetoho ea motlakase.
Ho akaretsa
Li-sensor tsa holo li fana ka melemo e mengata joalo ka ts'epo e hlokahalang haholo, ts'ebetso ea lebelo le holimo, le lihlahisoa tsa motlakase tse reriloeng esale pele le li-angles. Basebelisi le bona ba e rata ka lebaka la bokhoni ba eona ba ho sebetsa maemong a fapaneng a mocheso. Li sebelisoa haholo likoloing tse tsamaeang, lisebelisoa tsa othomathike, lisebelisoa tsa ho sebetsana le likepe, mechini ea temo, metjhini e sehang le e khutlisang morao, le mechini ea ho lokisa le ho paka.
