Indlela yokuthola ukumelana:

Okokuqala, ukuhlola ukubukeka

Hlola ukuthi izimpawu zicacile, upende ovikelayo uqinile, ngaphandle kokushiswa, izibazi, imifantu kanye nokugqwala, futhi i-resistor iseduze nephini. Ngama-potentiometers, kufanele futhi uhlole ukuthi i-shaft ejikelezayo iyaguquguquka, iyanwebeka futhi ikhululekile. Uma kukhona ukushintsha, hlola ukuthi isenzo sokushintsha sijwayelekile, njll.

Okwesibili, ukutholwa kwe-multimeter

1. Uma wahlulela ukuthi ukumelana kuhle noma kubi nge-pointer multimeter, kufanele uqale ukhethe igiya lokulinganisa, bese ufaka igiya lokukhulisa igiya egiyeni elifanele. Ngokuvamile, igiya le-RX1 lingakhethelwa ama-resistors angaphansi kuka-100 ohms, igiya le-RX10 lama-resistors phakathi kuka-100 ohms no-1kohms, igiya le-RX100 lama-resistors phakathi kuka-1kohms no-10kohms, igiya le-RX1K lama-resistors angaphezu kuka-100kohms.

2. Ngemuva kokukhetha igiya lokulinganisa, linganisa igiya lokumelana le-multimeter kuya ku-0. Indlela yokulinganisa u-0 iwukuthi: i-short-circuit imigoqo yensimbi yama-probe amabili we-multimeter, futhi ubheke ukuthi i-pointer ifinyelela isikhundla sika-0. Uma ingekho endaweni ka-0, lungisa i-pointer ye-zero knob yokulungisa ukuze ikhombe endaweni ka-0 yesikali sokumelana.

3. Khona-ke, xhuma ama-probe amabili we-multimeter emikhawulweni emibili ye-resistor ngokulandelanayo, futhi ama-probes kufanele akhombe esikalini sokumelana esihambisanayo. Uma ama-probes enganyakazi futhi engazinzile, noma inani elibonisiwe lihluke kakhulu kunani elibonisiwe ku-resistor, kusho ukuthi i-resistor yonakalisiwe.

4. Uma wahlulela ukuthi ukumelana kuhle noma kubi nge-multimeter yedijithali, qala ngokulungisa i-knob yegiya ye-multimeter egiyeni elifanele legiya le-ohm. Ngokuvamile, amagiya angama-200 angakhethelwa ama-resistors angaphansi kwama-ohms angama-200, ama-200-2K ohms angakhethelwa amagiya angu-2k, ama-20-20K ohms angakhethelwa amagiya angama-20k, ama-200K-200M ohms angakhethelwa ama-2M ohms. Ukumelana kwe-2M-20M ohm kungu-20M, futhi ukumelana kwe-20M ohm noma ngaphezulu kungu-200M.

Okuqukethwe okwethulwe ngenhla kuyindlela yokuthola ikhwalithi yokumelana. Ngalezi zindlela zokubona ezilula, ungakwazi ukubona ngokushesha ikhwalithi yokumelana, okuletha ukunethezeka okukhulu ekusebenziseni kwakho.

Kuyini okwenzekayo lapho ukumelana kwephulwa?

Lapho ukumelana kwephukile, ngokuvamile ukuthi ukumelana kuba kukhulu, futhi ezinye zazo zizoba zincane, noma eziningi zazo zivulekile.

Iluphi uphawu lokwephulwa kokumelana ne-blower?

Ukumelana ne-blower ikakhulukazi kulawula isivinini se-blower. Uma i-blower resistance iphukile, isivinini se-blower siyefana kumagiya ahlukene. Ngemva kokwephulwa kokumelana ne-blower, i-knob yokulawula ivolumu yomoya ilahlekelwa umsebenzi wayo wokulawula isivinini. Kuzoholela ekungakwazini ukulungisa ukuphuma komoya; Alikho igiya le-1234, indawo yomoya eyodwa kuphela; Kufanele kube okukhipha umoya omkhulu; Kukhona nabanye abalandeli abangasebenzi ngqo.

Lapho i-varistor ijwayelekile, ukumelana kwayo akupheli. Ixhunywe ngokuhambisana kuzo zombili iziphetho zamandla kagesi, odlala indima yokuvikela ukugcwala kwe-overvoltage. Lapho i-voltage yokufaka idlula inani elithile, ukumelana kwayo ngokuzumayo kuba kuncane, okwenza isekethe ibe mfushane, ifinyeze ifuse ngenkani, futhi idlale indima yokuvikela izinto zikagesi. Ngaphansi kwezimo ezijwayelekile, i-silicon esheshayo ye-inverter kulula ukuphuka. Uma i-silicon ye-rectifier iphukile, kungenzeka kube nokugcwala ngokweqile noma i-overcurrent kungazelelwe. Ngenxa yokuphazamiseka kwe-trigger okubangelwa ukuphazamiseka komthwalo kanye nokuguquguquka kwamandla, i-silicon yokulungisa nayo izolimala, futhi izinkinga ezithile zidinga ukuhlaziywa ngokuvumelana nesimo somonakalo.

Isizathu sokuthi kungani ukumelana nabalandeli be-air conditioner yemoto kuzovutha ngokuqhubekayo;

1, i-compressor noma isifunda sokulawula esibangelwa isifunda esifushane.

2, i-condenser motor, i-compressor electromagnetic clutch, ukwehluleka kwe-evaporator motor.

3. I-fuse yesiphephetha-moya semoto ayihlangabezani nezidingo, futhi inani lamanje lincane.

4. Kukhona isifunda esifushane ohlelweni lwe-air conditioning, olubangelwa umthwalo omningi we-compressor.
