Uburyo bwo kumenya guhangana:

Icyambere, kugenzura isura

Reba neza ko ibimenyetso bisobanutse, irangi ririnda ntirisanzwe, nta gutwika, inkovu, gucamo no kwangirika, kandi résistoriste ihura cyane na pin.Kuri potentiometero, ugomba kandi kugenzura ko uruziga ruzunguruka rworoshye, rworoshye kandi rwiza.Niba hari switch, reba niba ibikorwa byo guhindura ari ibisanzwe, nibindi.

Icya kabiri, kumenya multimeter

1. Mugihe usuzumye niba kurwanya ari byiza cyangwa bibi hamwe na multimeter yerekana, ugomba kubanza guhitamo ibikoresho byo gupima, hanyuma ugashyira ibikoresho byo gukuza ibikoresho mubikoresho bikwiye.Mubisanzwe, ibikoresho bya RX1 birashobora gutoranywa kubarwanya munsi ya 100 oms, ibikoresho bya RX10 kubarwanya hagati ya ohm 100 na 1kohms, ibikoresho bya RX100 kubarwanya hagati ya 1kohms na 10kohms, ibikoresho bya RX1K kubarwanya hejuru ya 100kohms.

2. Nyuma yo guhitamo ibikoresho byo gupimisha, koresha kalibari ibikoresho byo guhangana na multimeter kugeza kuri 0. Uburyo bwo guhinduranya 0 ni: kuzenguruka-bigufi ibyuma byerekeranye na probe ebyiri za multimeter, hanyuma urebe niba icyerekezo kigera kumwanya wa 0. Niba itari kumwanya wa 0, hindura icyerekezo cya zeru zeru knob kugirango werekane kumwanya wa 0 wikigereranyo.

3. Noneho, huza ibice bibiri bya multimeter kumpande zombi za résistoriste, hanyuma iperereza rigomba kwerekana igipimo gihuye nacyo.Niba iperereza ridahungabana kandi ridahindagurika, cyangwa agaciro kerekanwe gatandukanye cyane nagaciro kerekanwe kuri résistor, bivuze ko résistoriste yangiritse.

4. Mugihe usuzumye niba kurwanya ari byiza cyangwa bibi hamwe na multimeter ya digitale, banza uhindure ibikoresho bya bikoresho bya multimeter kubikoresho bikwiye bya ohm.Mubisanzwe, ibyuma 200 birashobora gutoranywa kubarwanya munsi ya 200 oms, 200-2K ohm irashobora gutoranywa kubikoresho 2k, 20-20K oms irashobora gutoranywa kubikoresho 20k, 200K-200M oms irashobora gutoranywa kuri 2M oms.Kurwanya 2M-20M ohm ni 20M, naho kurwanya 20M ohm cyangwa kurenga ni 200M.

Ibirimo byavuzwe haruguru nuburyo bwo kumenya ubwiza bwurwanya.Binyuze muri ubu buryo bworoshye bwo gutahura, urashobora guhita umenya ubwiza bwurwanya, buzana ibyoroshye cyane kumikoreshereze yawe.

Ni ibihe bintu iyo kurwanya byacitse?

Iyo imyigaragambyo ivunitse, mubisanzwe ni uko kurwanya birushaho kuba binini, kandi bimwe muribi bizaba bito, cyangwa ibyinshi bikaba bifunguye.

Nibihe bimenyetso birwanya kurwanya blower?

Kurwanya blower bigenzura cyane cyane umuvuduko wa blower.Niba igihagararo cya blower cyacitse, umuvuduko wa blower ni kimwe mubikoresho bitandukanye.Nyuma yo kurwanya blower ivunitse, kugenzura amajwi yo mu kirere bitakaza imikorere yayo yo kugenzura umuvuduko.Bizaganisha ku kudashobora guhindura ibyasohotse mu kirere;Nta bikoresho 1234, isohoka rimwe gusa;Igomba kuba ikirere kinini gisohoka;Hariho nabafana bamwe badakora muburyo butaziguye.

Iyo varistor isanzwe, irwanya ryayo ntirigira iherezo.Ihujwe kuburinganire kumpande zombi zitanga amashanyarazi, igira uruhare mukurinda ingufu zirenze urugero.Iyo voltage yinjiye irenze agaciro runaka, irwanya ryayo ritunguranye riba rito, bigatuma uruziga rugufi-ruzunguruka, rugabanya fuse ku gahato, kandi rukagira uruhare mu kurinda ibikoresho byamashanyarazi.Mubihe bisanzwe, inverter yihuta silicon iroroshye kumeneka.Niba silicon ikosora ivunitse, harashobora kubaho gutungurana gutunguranye cyangwa kurenza urugero.Kubera ihungabana ryatewe no guhungabanya imizigo no guhindagurika kwingufu, silikoni ikosora nayo izangirika, kandi ibibazo byihariye bigomba gusesengurwa ukurikije uko byangiritse.

Impamvu ituma abafana barwanya ibyuma bifata ibyuma bifata ibyuma bizana umuriro;

1, compressor cyangwa kugenzura umuzenguruko uterwa numuzunguruko mugufi.

2, moteri ya condenser, compressor electromagnetic clutch, moteri ya moteri.

3. Ihuriro ryumuyaga uhumeka ryimodoka ntirujuje ibisabwa, kandi agaciro kariho ni nto.

4. Hariho uruziga rugufi muri sisitemu yo guhumeka, iterwa nuburemere bukabije bwa compressor.
