Indlela yokuthola ukumelana:

Okokuqala, ukuhlolwa kokubonakala

Bheka ukuthi izimpawu zicacile, upende wokuvikela uqinile, ngaphandle kokushayisana, izibazi, imifantu kanye nokugqwala, futhi umphikisi ubhekene nePin. Kwama-Potentiometer, kufanele futhi ubheke ukuthi ishaft ejikelezayo iyashintshana, i-Eastic futhi inethezekile. Uma kukhona switch, hlola ukuthi isenzo sokushintshana sijwayelekile, njll.

Okwesibili, ukutholwa kwe-multimeter

1. Lapho ukwahlulela ukuthi ukumelana kuhle noma kubi nge-pointer multimeter, kufanele uqale ukhethe igiya lokulinganisa, bese ubeka ifindo legiya lokukhulisa kugiya elifanele. Ngokuvamile, amagiya e-Rx1 angakhethwa abaphikiswa ngaphansi kwama-100 ohms, amagiya e-Rx10 abaphikisayo phakathi kwama-OHMS ayi-100 kanye ne-10kohms ye-10kohms, amagiya e-Rx1k, amagiya e-Rx1k aphezulu kakhulu nge-100kohms.

2. Ngemuva kokukhetha amagiya wokulinganisa, ulinganise igiya lokumelana ne-multimeter kuye ku-0

3. Bese, xhuma ama-multimeter amabili we-multimeter kuya emaphethelweni womabili e-resistor ngokulandelana, futhi izingquzo kufanele zikhombe ezikalini ezihambisanayo zokumelana. Uma kungenzeka ukuthi kungenzeka ukuthi ama-IMobile futhi angazinzile, noma inani elikhonjisiwe lihlukile kakhulu kunani elikhonjisiwe ku-resistor, kusho ukuthi ukumelana kulinyazwe.

4. Lapho ukwahlulela ukuthi ukumelana kulungile noma kubi nge-multimeter yedijithali, qala ulungise i-knob ye-multimeter kwigiya elifanele legiya le-ohm. Ngokuvamile, amagiya angama-200 angakhethwa abaphikisayo abangaphansi kwama-OHM angama-200, 200-2k Ohms angakhethwa amagiya we-2k, 20-20k ohms angakhethwa amagiya angama-20K, 200K-200m Ohms angakhethwa ngama-2m ohms. Ukumelana kwe-2m-20m ohm kuyinto engama-20m, kanye nokumelana kuka-20m ohm noma ngaphezulu ngu-200m.

Okuqukethwe okwethulwe ngenhla kuyindlela yokuthola ikhwalithi yokumelana. Ngalezi zindlela ezilula zokutholwa, ungathola ngokushesha ikhwalithi yokumelana, okuletha lula ukusetshenziswa kwakho.

Yini into ephukile lapho ukumelana kwephuka?

Lapho ukumelana kwephukile, ngokuvamile kungukuthi ukumelana kuba nkulu, kanti abanye babo bazoba mncane, noma iningi labo livulekile.

Yiluphi uphawu lokumelana nokuqhuma okuqhuma okuphukile?

Ukumelana nokuqhuma kwe-Blower ikakhulukazi kulawula ijubane le-blower. Uma ukumelana kwe-Blower kuphukile, ijubane le-blower liyefana kumagiya ahlukene. Ngemuva kokuthi ukumelana nokuqhuma kwe-blower kuphukile, ifindo lokulawula umoya komoya lilahlekelwa umsebenzi walo wejubane lokulawula. Kuzoholela ekungakwazi ukulungisa ukuphuma komoya; Alikho amagiya ayi-1234, okuphuma komoya okukodwa; Kufanele kube ukuphuma komoya omkhulu; Kukhona futhi abalandeli abangasebenza ngqo.

Lapho i-varistor ijwayelekile, ukumelana kwayo akunamkhawulo. Ixhumeke ngokufana emikhawulweni yomibili yamandla, edlala indima yokuvikelwa ngokweqile. Lapho i-voltage yokufaka idlula inani elithile, ukumelana kwalo kungazelelwe kube yincane, okwenza umjikelezo usheshe, ukufushanisa ngenkani i-fuse, futhi ukudlala indima yokuvikela izinto zikagesi. Ngaphansi kwezimo ezijwayelekile, i-Inverter Fast Silicon kulula ukuyiyeka. Uma i-silicon enobulungisa iphukile, kungenzeka ukuthi ingaba ngaphezulu ngokweqile noma i-Overcurent. Ngenxa yokuphazamiseka kwesisusa esibangelwa ukuphazamiseka kwemithwalo kanye nokuguquguquka kwamandla, i-silicon elungisa inqubo izolimala futhi, futhi izinkinga ezithile zidinga ukuhlawuliswa ngokuya ngesimo somonakalo.

Isizathu esenza ukuthi ukumelana nabalandeli komoya komoya kuzoshisa ngokuqhubekayo;

1, i-compressor noma i-control circuit ebangelwa umjikelezo omfushane.

I-2, i-condenser motor, i-compressor electromagnetic clutch, ukwehluleka kwemoto ye-evaporator.

I-3. I-Fuse ye-Automobile Air Conding Fan ayihlangabezani nezidingo, futhi inani lamanje lincane.

4. Kunomjikelezo omfushane ohlelweni lokufaka umoya, okubangelwa umthwalo omkhulu kakhulu we-compressor.
