Mokhoa oa ho lekola sensor ea mocheso ka multimeter

Na koloi ea hau e chesa haholo?

Na nalete ea mocheso ka har'a dashboard e khomaretsoe ho chesa kapa ho bata?

A na u boetse u na le ho se sebetse hantle le bothata ba ho qala enjene? 

Haeba karabo ea hau lipotsong tsena ke e, joale sensor ea mocheso e ka 'na ea e-ba eona molato' me u lokela ho etsa liteko ho eona ho fumana hore na e hloka ho nkeloa sebaka kapa che.

Ntle le ho senya nako, a re qaleng.

Sensor ea mocheso ke eng?

Sensor ea mocheso kapa sensor ea mocheso o pholileng ke karolo ea koloi e lekanyang mocheso oa enjene.

Ha e lekanya mocheso, mochine o pholileng o romela molaetsa o chesang kapa o batang ho unit control unit (ECU), 'me ECU e sebelisa lipontšo tsena ho etsa liketso tse' maloa.

ECU e sebelisa data ea sensor ea mocheso ho fetola hantle ente ea mafura le nako ea ho tima.

Likoloing tse ling, data ea sensor ea mocheso e boetse e sebelisoa ho bulela le ho tima fene e futhumatsang ea enjine, kapa ho fetisetsoa ho sensor e deshebotong ea koloi.

Matšoao a sensor ea mocheso e fosahetseng

Ka lebaka la karolo ea sensor ea mocheso o pholileng ka enjene le hore na e ama mesebetsi ea ECU joang, matšoao a sensor e mpe a bonolo ho a bona.

1. Ho chesa haholo ha koloi

Sensor e fosahetseng ea mocheso e ka romela letšoao le chesang kamehla ho ECU, e leng se bolelang hore ha enjene e hloka ho pholile, ECU ha e arabe ka tsela e nepahetseng 'me fan ha e bulela.

Enjene e tsoela pele ho futhumala ho fihlela e futhumala ho feta tekano, e leng se ka bakang mollo. 

2. Nako e fosahetseng ea ho tima

Joalokaha ho boletsoe pejana, ECU e boetse e sebelisa lintlha tse tsoang ho sensor ea mocheso ho fumana nako ea ho chesa.

Sena se bolela hore haeba mocheso oa mocheso o hlōleha, ho qala enjene ho tla ba thata ka lebaka la nako e fosahetseng ea ho khantša.

3. Ente e sa nepahalang ea mafura

Sensor e mpe ea mocheso e baka ente e mpe ea mafura ka enjene, e lebisang matšoao a mang a mangata.

Tsena li tloha ho mosi o motšo o tsoang ka pompong ho ea ho sebaka se tlase sa koloi, ho se sebetse hantle ha enjine le ho se sebetse hantle ha enjine ka kakaretso.

Haeba maemo ana a bolokoa nako e telele, enjene e ka senyeha. 

Lisebelisoa tsa Teko ea Sensor ea Mocheso

Ho na le mekhoa e 'meli ea ho hlahloba sensor ea mocheso o pholileng,' me mekhoa ena e na le lisebelisoa le lisebelisoa tsa eona tse khethehileng.

Ho hlahloba sensor ea mocheso o tla hloka:

• Multimeter
• Metsi a chesang le a batang

Mokhoa oa ho lekola sensor ea mocheso ka multimeter

Beha motlakase oa multimeter ho DC, tlosa sensor ea mocheso koloing, beha probe e khubelu holim'a phini e hole le letona le phuputso e ntšo phini e hole le letšehali. Kenya sensor metsing a chesang le a batang 'me u hlahlobe ho baloa ha voltage ho multimeter.

Ona ke ts'ebetso ea mantlha ea ho leka sensor ea mocheso ka multimeter, empa ha se eona feela. 

1. Fumana sensor ea mocheso

Hangata sensor ea mocheso ke sesebelisoa se senyenyane se setšo se haufi le ntlo ea thermostat.

Ho fumana ntlo ea thermostat, o latela hose e tlohang ho radiator ho ea enjene.

Qetellong ea hose ena ke ntlo ea thermostat, 'me haufi le eona hangata ho na le sensor ea mocheso.

Boemo bona bo ka fapana ho latela mofuta oa koloi, empa e lula e atile har'a likoloi tsa sejoale-joale.

Leha ho le joalo, bakeng sa literaka, sensor ea mocheso e ne e ka fumanoa haufi le cylinder ea tšepe ka har'a cylinder block (ho kenya ka bongata).

U tlameha ho tlosa plenum ea ho kena ho eona le ho hira mochini oa setsebi - bethe e sireletsehileng ho qoba ho senya enjene. 

2. Ntša sensor ea mocheso

Sensor ea mocheso e hokahane le enjene ka mohala oa mohala.

E hokahane le khoele ea likhoele ka li-terminals tsa eona tsa tšepe 'me u batla feela ho arola tse peli.

Tlosa sensor ho tloha ho sebono sa wiring. 

PES: Pele o bula sekoaelo sa koloi ho fumana le ho tlosa sensor ea mocheso, etsa bonnete ba hore enjene e tima 'me ha e sebetse bonyane metsotso e 15. Sena sea hlokahala e le hore a se ke a u chesa.

Ha u se u fumane sensor ea mocheso 'me u e tlositse enjene, multimeter ea hau e ea sebetsa.

3. Multimeter pinout

Hokela lithapo tsa multimeter ho li-terminals tsa sensor ea mocheso.

Li-sensor tse ling li ka ba le li-terminals tse fihlang ho tse 5, empa etsa bonnete ba hore li-sensor li behiloe lipheletsong tse peli tsa sehokelo sa sensor.

Tšebeliso ea likotoana tsa likoena e nolofatsa tšebetso eohle haholo. Ha o hokela li-multimeter lead, ha u batle hore li tšoarane.

U mpa u hokela probe e khubelu ho theminale e ka ho le letona le ho lets'oao le letšo sebakeng se ka ho le letšehali.

4. Sensor ea ho qoelisoa metsing a batang

Ho qoelisoa ha sensor metsing a batang le a chesang hoa hlokahala ho fumana mocheso oa litšupiso bakeng sa litekanyo.

U fumana metsi a ka bang 180ml, kenya likotoana tsa leqhoa ka har'a eona, 'me u netefatse hore e ka ba 33°F (1°C). Thermostat ea dijithale e ka thusa.

5. Nka litekanyo

Ho fumana sensor ea mocheso ho hloka hore u hlahlobe hore na e ntša palo e nepahetseng ea motlakase.

Ho etsa sena, o seta mohala oa multimeter ho ea ho voltage ea DC ebe o rekota hore na liphetho tsa multimeter li hlahisa eng. 

Haeba multimeter e sa balehe, leka ho lokisa li-probe ho li-terminals.

Haeba e ntse e sa fane ka ho bala, joale sensor e mpe 'me ha ho hlokahale hore u etse liteko tse ling hape.

Palo e nepahetseng ea li-multimeter ke hoo e ka bang 5 volts.

Leha ho le joalo, sena se ipapisitse le mofuta oa sensor ea mocheso, ka hona, ka kopo sheba buka ea litaelo ea mong'a koloi ea hau. Haeba u bala, e ngole fatše.

6. Sensor ea ho qoelisoa ka metsi a chesang

Joale qoelisa sensor ka 180 ml ea metsi a belang (212 ° F / 100 ° C).

7. Nka litekanyo

Ha multimeter e ntse e le sebakeng sa motlakase oa DC, hlahloba palo ea motlakase 'me u e rekote. 

Tekong ena ea metsi a belang, tekanyo e ntle ea mocheso e fana ka 'malo oa multimeter oa hoo e ka bang 25 volts.

Ehlile, sena se ipapisitse le mohlala mme o batla ho bua ka bukana ea koloi kapa sensor ea mocheso.

8. Reita liphetho

Kamora ho etsa liteko tsena tsa metsi a batang le a chesang, o tla bapisa litekanyo tsa hau le litlhoko tsa mofuta oa koloi ea hau. 

Haeba litekanyo tse batang le tse chesang li sa lumellane, sensor ha e na phoso 'me e tlameha ho nkeloa sebaka. 

Ka lehlakoreng le leng, haeba li lumellana, sensor e sebetsa hantle 'me mathata a hau a ka amana le likarolo tse ling.

Mona ke video e nolofatsang ts'ebetso ea ho etsa liteko tsa metsi a batang le a chesang ho sensor ea mocheso.

Ho hlahloba lithapo tsa sensor ea mocheso   

U ka leka lithapo tsa sensor ka ho sebelisa lithapo tsa jumper ho theola mohala oa tšepe sebakeng se haufi sa tšepe. 

Qala enjene, theola li-sensor tse nang le mohala ka thapo ea jumper 'me u hlahlobe sensor ea mocheso deshibotong.

Haeba lithapo li hlophisitsoe hantle, sekala se baloa hoo e ka bang halofo ea ho chesa le ho bata.

Haeba u sa khone ho latela tsela ea likhoele, re boetse re na le tataiso bakeng sa seo.

fihlela qeto e

Sensor ea mocheso ke karolo e nyane e bapalang karolo e kholo haholo bophelong le ts'ebetsong ea enjene ea hau.

Haeba u hlokomela matšoao, latela litaelo tsa rona 'me u sebelise multimeter ho lekanya motlakase o hlahisoang ho li-terminals tsa eona.

Ho hira setsebi sa mak'henike ho ka thusa haeba mehato e bonahala e le boima.

Lipotso tse atisang ho botsoa

U ka tseba joang haeba thermometer ea hau e robehile?

Matšoao a mang a sensor e mpe ea mocheso a kenyelletsa mocheso o feteletseng oa enjene, lebone la enjine le ntseng le tuka, mosi o motšo o tsoang ho mosi, sebaka se tlase, ho se sebetse hantle ha enjine, le bothata ba ho qala koloi.

Hobaneng ha sensor ea ka ea mocheso e sa sisinyehe?

Tekanyo ea mocheso e ka 'na ea se ke ea sisinyeha ka lebaka la mathata a sensor ea mocheso. The gauge ea khatello e ka lula e leketlile ho chesa kapa ho bata, ho itšetlehile ka hore na gauge e senyehile neng.

Joang ho lekanya khanyetso ea sensor ea mocheso?

Beha li-multimeter ho li-ohms, beha lintlha tsa tlhahlobo ho li-terminals tsa sensor, ka ho khetheha u sebelise likotoana tsa alligator, 'me u hlahlobe ho bala ho hanyetsa. Ho bala ho lumellanang ho itšetlehile ka mohlala oa sensor.

Na sensor ea mocheso e na le fuse?

Sensor ea mocheso ha e na fuse ea eona, empa e sebelisa terata ea fusible ho sehlopha sa lisebelisoa. Haeba fuse ena e foka, sensor ea mocheso ha e sebetse 'me fuse e lokela ho nkeloa sebaka.
