Indlela Yokuhlola I-Stator Nge-Multimeter (Umhlahlandlela Wokuhlola Wendlela Ezi-3)

I-alternator, ehlanganisa i-stator ne-rotor, inika injini amandla ngokuguqula amandla emishini ibe ugesi futhi ishaja nebhethri. Yingakho ke, uma kukhona okungahambi kahle nge-stator noma i-rotor, imoto yakho izoba nezinkinga ngisho noma ibhethri lilungile. 

Nakuba i-rotor inokwethenjelwa, ijwayele ukwehluleka ngoba iqukethe amakhoyili e-stator ne-wiring. Ngakho-ke, ukuhlola i-stator nge-multimeter enhle kuyisinyathelo esibalulekile ekuxazululeni ama-alternator. 

Izinyathelo ezilandelayo zizokusiza ukuthi uhlole i-stator nge-multimeter yedijithali. 

Ungahlola kanjani i-stator nge-multimeter?

Uma unenkinga yokushaja imoto noma isithuthuthu sakho, sekuyisikhathi sokuthi ukhiphe i-DMM yakho. 

Okokuqala, setha i-DMM ibe ama-ohms. Ngaphezu kwalokho, uma uthinta izintambo zamamitha, isikrini kufanele siveze ama-ohms angu-0. Ngemva kokulungisa i-DMM, hlola ibhethri ngemikhondo yamamitha.

Uma i-DMM ifundeka cishe ku-12.6V, ibhethri lakho lihle futhi inkinga kungenzeka kakhulu ngekhoyili ye-stator noma intambo ye-stator. (1)

Kunezindlela ezintathu zokuhlola i-stators:

1. Ukuhlolwa kwe-Stator static

Ukuhlola okumile kuyanconywa uma unenkinga yokushaja imoto noma isithuthuthu sakho. Futhi, lesi ukuphela kwesivivinyo ongasisebenzisa lapho imoto yakho ingaqali. Ungakwazi ukususa i-stator enjinini yemoto noma uyihlole enjinini ngokwayo. Kodwa ngaphambi kokuhlola amanani okumelana nokubheka okufushane ezintanjeni ze-stator, qiniseka ukuthi imoto ivaliwe. (2)

Ekuhlolweni kwe-stator emile, izinyathelo ezilandelayo ziyenziwa:

(a) Vala injini 

Ukuze uhlole ama-stators kwimodi emile, injini kufanele icishwe. Njengoba kushiwo ngaphambili, uma imoto ingeke iqale, ukuhlolwa kwe-stator static ukuphela kwendlela yokuhlola ama-stators. 

(b) Setha i-multimeter

Setha i-multimeter ibe yi-DC. Faka umthofu omnyama we-multimeter kujack COM emnyama, okusho ukuthi Okujwayelekile. Intambo ebomvu izongena endaweni ebomvu enezimpawu ezithi "V" kanye no-"Ω". Qiniseka ukuthi intambo ebomvu ayixhunyiwe kusixhumi se-Ampere. Kufanele ibe ku-slot ye-Volt/Resistance kuphela.  

Manje, ukuze uhlole ukuqhubeka, vula iknob ye-DMM futhi uyisethe kuphawu lwebhiphu njengoba uzozwa ibhiphu ukuze uqiniseke ukuthi yonke into ilungile ngesekhethi. Uma ungakaze usebenzise i-multimeter ngaphambilini, sicela ufunde imanuwali yayo yomsebenzisi ngaphambi kokuyisebenzisa.

(c) Yenza ukuhlolwa okumile

Ukuze uhlole ukuqhubeka, faka womabili ama-multimeter probe kumasokhethi e-stator. Uma uzwa ibhiphu, umjikelezo muhle.

Uma une-stator yezigaba ezintathu, udinga ukwenza lokhu kuhlola izikhathi ezintathu, ufaka ama-multimeter probes esigabeni 1 nesigaba sesi-2, isigaba sesi-2 nesigaba sesi-3, bese isigaba sesi-3 nesigaba 1. Uma i-stator ilungile, wena kufanele izwe ibhiphu kuzo zonke izimo.   

Isinyathelo esilandelayo ukuhlola okufushane ngaphakathi kwe-stator. Khipha ucingo olulodwa kusokhethi ye-stator bese uthinta ikhoyili ye-stator, i-chassis yaphansi noma yemoto. Uma kungekho isignali yomsindo, khona-ke akukho ukujikeleza okufushane ku-stator. 

Manje, ukuze uhlole amanani okumelana, setha inkinobho ye-DMM kuphawu Ω. Faka umkhondo we-multimeter kumasokhethi we-stator. Ukufundwa kufanele kube phakathi kuka-0.2 ohms no-0.5 ohms. Uma ukufundwa kungaphandle kwalobu bubanzi noma kulingana nokungapheli, lokhu kuwuphawu olucacile lokuhluleka kwe-stator.

Sikweluleka ukuthi ufunde imanuwali yesevisi yemoto yakho ukuze wazi ukufundwa okuphephile.

2. Ukuhlolwa kwe-Stator ashukumisayo

Ukuhlolwa kwe-stator ashukumisayo kwenziwa ngokuqondile emotweni futhi kusekela i-multimeter kumodi ye-AC. Lokhu kuhlola i-rotor, equkethe omazibuthe futhi izungeza i-stator. Ukwenza uhlolo lwe-stator oluguqukayo, izinyathelo ezilandelayo ziyenziwa:

(a) Vala umlilo

Ukulandela inqubo efanayo neyesivivinyo esimile, faka umkhondo we-multimeter kumasokhethi we-stator. Uma i-stator inezigaba ezintathu, lokhu kuhlolwa kufanele kwenziwe izikhathi ezintathu ngokufaka ama-probe ezisekelweni zesigaba 1 nesigaba sesi-2, isigaba sesi-2 nesigaba sesi-3, isigaba sesi-3 nesigaba 1. Ngokucisha umlilo, akufanele uthathe noma yikuphi ukufundwa lapho wenza lokhu kuhlola.

(b) Ukubasa ngeswishi yokushisa

Qala injini bese uphinda ukuthungela okungenhla ngezigaba ngayinye. I-multimeter kufanele ibonise ukufundwa okungaba ngu-25V.

Uma ukufundwa kwanoma yiziphi izigaba kuphansi kakhulu, yithi cishe ku-4-5V, lokho kusho ukuthi kunenkinga ngesinye sezigaba futhi sekuyisikhathi sokushintsha i-stator.

(c) Khuphula isivinini senjini

Buyekeza injini, ukhuphule i-rpm ifinyelele cishe ku-3000 bese uyivivinya futhi. Ngalesi sikhathi i-multimeter kufanele ibonise inani elingaba ngu-60 V, futhi lizokhula kanye nenani lama-revolutions. Uma ukufundwa kungaphansi kwe-60V, inkinga iku-rotor. 

(d) Ukuhlolwa kwesilungisi somlawuli

Isilawuli sigcina i-voltage ekhiqizwa i-stator ngaphansi komkhawulo ophephile. Xhuma i-stator yemoto yakho kusilawuli bese usetha i-DMM ukuthi ihlole ama-amps esikalini esiphansi kakhulu. Vula okomlilo nazo zonke izibasi bese unqamula ikhebula lebhethri elinegethivu. 

Xhuma imikhondo ye-DMM ngochungechunge phakathi kwesigxobo esinegethivu sebhethri nesigxobo esinegethivu. Uma zonke izivivinyo zangaphambilini zilungile, kodwa i-multimeter ifundeka ngaphansi kwama-amps angu-4 phakathi nalokhu kuhlolwa, isilungisi somlawuli sinephutha.

3. Ukuhlola okubonakalayo

I-Static ne-dynamic yizindlela ezimbili zokuhlola izibukeli. Kodwa, uma ubona izimpawu ezicacile zomonakalo ku-stator, isibonelo uma ubukeka ushisiwe, lokhu kuyisibonakaliso esicacile se-stator embi. Futhi awudingi i-multimeter kulokhu. 

Ngaphambi kokuthi uhambe, ungabheka ezinye izifundo ngezansi. Kuze kube isihloko sethu esilandelayo!
