Ukwethulwa kwesilawuli sokushisa nomswakama

Uhlolojikelele

Isilawuli sezinga lokushisa kanye nomswakamo sisekelwe kukhompuyutha encane ye-single-chip ewumgogodla wokulawula, futhi samukela izinzwa zokushisa nokusebenza okuphezulu ezingeniswa kwamanye amazwe, ezingakala futhi zilawule amasignali okushisa nomswakama ngesikhathi esifanayo, futhi ibone isibonisi sedijithali esiyikristalu ewuketshezi. .Umkhawulo ophansi usethiwe futhi ubonisiwe, ukuze ithuluzi likwazi ukuqala ngokuzenzakalelayo i-fan noma i-heater ngokuvumelana nesimo sendawo, futhi ilungise ngokuzenzakalelayo izinga lokushisa langempela kanye nomswakama wendawo elinganisiwe.

Wisimiso se-orking

Isilawuli sezinga lokushisa nomswakama ikakhulukazi sakhiwe izingxenye ezintathu: inzwa, isilawuli kanye ne-heater.Umgomo wayo wokusebenza umi kanje: inzwa ithola ulwazi lokushisa nomswakama ebhokisini, bese idlulisela kusilawuli ukuze sihlaziywe futhi sicutshungulwe: lapho izinga lokushisa nomswakama ebhokisini kufinyelela noma Uma inani elimisiwe lidluliwe, othintana naye odluliselwe kusilawuli sivaliwe, i-heater inikwe amandla futhi iqala ukusebenza, ukushisa noma ukushaya umoya ebhokisini;ngemva kwesikhathi esithile, izinga lokushisa noma umswakama osebhokisini ukude nenani elibekiwe, futhi Oxhumana nabo abadluliselwe entweni esetshenziswayo bayavula, bafudumale noma baphephethe izitobhi.

Aisicelo

Imikhiqizo yesilawuli sokushisa nomswakama isetshenziselwa kakhulu ukulungisa nokulawula izinga lokushisa langaphakathi kanye nomswakama wamakhabethe okushintsha amandla kagesi aphakathi nendawo naphezulu, amabhokisi agcinayo, amakhabethe enethiwekhi eyindandatho, amabhokisi oguquli kanye nezinye izinto zokusebenza.Ingavimbela ngokuphumelelayo ukwehluleka kwemishini okubangelwa izinga lokushisa eliphansi kanye nokushisa okuphezulu, kanye nezingozi ze-creepage ne-flashover ezibangelwa umswakama noma ukufingqa.

Ukwahlukanisa

Izilawuli zezinga lokushisa kanye nomswakamo zihlukaniswa kakhulu zibe izinhlobo ezimbili: uchungechunge olujwayelekile nochungechunge oluhlakaniphile.

Isilawuli sokushisa esivamile nesiswakamo: Senziwe ngezinzwa ze-polymer nezinzwa zomswakama ezingenisiwe, kuhlanganiswe nesekethe ye-analog ezinzile kanye nobuchwepheshe bokushintshwa kwamandla kagesi.

Izinga lokushisa elihlakaniphile nesilawuli somswakama: Sibonisa amanani okushisa nokuswakama ngendlela yamashubhu edijithali, futhi sinehitha, inkomba yephutha lenzwa, nemisebenzi yokudlulisela.Ithuluzi lihlanganisa ukulinganisa, ukubonisa, ukulawula nokuxhumana.Inokunemba okuphezulu kanye nebanga lokulinganisa elibanzi.Isilinganiso sezinga lokushisa nomswakama kanye nethuluzi lokulawula elifanele izimboni nezinkambu ezihlukahlukene.

Umhlahlandlela wokukhetha

Isilawuli esihlakaniphile sokushisa nomswakama singakala ezindaweni eziningi ngesikhathi esisodwa, futhi silawule izinga lokushisa kanye nomswakama wendawo ezungezile ezindaweni eziningi.Ulwazi olulandelayo kufanele lufakwe lapho u-oda: imodeli yomkhiqizo, ukunikezwa kwamandla asizayo, imingcele yesilawuli, ubude bekhebula, i-heater.

Mukulungiswa

Ukunakekelwa kwesilawuli sezinga lokushisa nomswakama:

1. Njalo hlola isimo sokusebenza sesilawuli.

2. Hlola ukuthi isimo sokusebenza sesiqandisi sijwayelekile (uma kune-fluoride encane, i-fluoride kufanele igcwaliswe ngesikhathi).

3. Hlola ukuthi amanzi ompompi anele yini.Uma amanzi engekho, vala iswishi yomswakama ngesikhathi ukuze ugweme ukushisisa okomswakama.

4. Hlola izintambo nezifudumezi ukuthi azivuzi yini.

5. Hlola ukuthi ikhanda lesifutho livimbekile yini.

6. Qaphela ukuthi iphampu yamanzi yomswakama izoyeka ukujikeleza ngenxa yezinhlaka zamanzi ezingasetshenziswa isikhathi eside, futhi iphendule i-fan blade ku-toggle port ukuze ijikeleze.

Izindaba ezidinga ukunakwa

1. “Ukuhlola kwansuku zonke” kwanyanga zonke kufanele kuhlole ubuqotho besilawuli sezinga lokushisa nomswakama, futhi kubike inkinga kusenesikhathi ukuze kugcinwe kusesimweni esihle.Ibanga phakathi kwepayipi lokushisa kanye nekhebula nocingo alikho ngaphansi kuka-2cm;

2. Izilawuli zezinga lokushisa nomswakama wawo wonke amabhokisi etheminali namabhokisi emishini kufanele abekwe endaweni yokufaka, ukuze izinga lokushisa nomswakama kulawulwe ngaphakathi kwebanga elijwayelekile.

3. Njengoba izinga lokushisa elibonisa idijithali nesilawuli somswakama singenawo umsebenzi wenkumbulo, njalo lapho amandla ecishiwe, izilungiselelo zefekthri zizobuyiselwa ngemva kokuba amandla evuliwe futhi, futhi izilungiselelo kufanele zisethwe kabusha.

4. Gwema ukusebenzisa isilawuli sezinga lokushisa nokuswakama endaweni enothuli oluningi.Zama ukufaka umshini endaweni evulekile.Uma igumbi elikalwa ngomshini likhulu, khulisa inani lezinzwa zokushisa nomswakama.

Troubleshooting

Amaphutha ajwayelekile ezilawuli zokushisa ezihlakaniphile:

1. Ngemva kokushisa isikhathi esithile, izinga lokushisa alishintshi.Hlala ubonisa izinga lokushisa le-ambient esizeni (njengezinga lokushisa elingu-25°C)

Lapho uhlangabezana nephutha elinjalo, qala uhlole ukuthi inani lesethingi le-SV limisiwe yini, ukuthi ukukhanya kwenkomba ye-OUT kwemitha kuvuliwe, futhi usebenzise “i-multimeter” ukuze ulinganise ukuthi ingabe amatheminali 3rd kanye ne-4th emitha anokukhiphayo okungu-12VDC.Uma ukukhanya kuvuliwe, amatheminali 3 kanye no-4 nawo anokukhipha okungu-12VDC.Kusho ukuthi inkinga ilele kudivayisi yokulawula yendikimba yokushisisa (efana ne-AC contactor, i-solid state relay, i-relay, njll.), hlola ukuthi idivayisi yokulawula inesekhethi evuliwe nokuthi ukucaciswa kwedivayisi akulungile (njenge- Idivayisi engu-380V kumjikelezo we-220), Kungakhathaliseki ukuthi umugqa uxhumeke ngokungalungile, njll. Ngaphezu kwalokho, hlola ukuthi inzwa ifushane yini (uma i-thermocouple ifushane, imitha ihlale ibonisa izinga lokushisa legumbi).

2. Ngemva kokushisisa isikhathi esithile, isibonisi sezinga lokushisa siyehla sincipha

Uma uhlangabezana nephutha elinjalo, i-polarity enhle nengalungile yenzwa ngokuvamile iyahlehliswa.Ngalesi sikhathi, kufanele uhlole i-wiring yokugcina okokufaka yenzwa yensimbi (i-thermocouple: 8 ixhunywe esigxotsheni esihle, futhi u-9 uxhunywe esigxotsheni esingesihle; I-PT100 ukumelana nokushisa: ?8 ixhunywe ocingweni olunombala owodwa, 9 no-10 zixhunywe ezintanjeni ezimbili zombala ofanayo).

3. Ngemva kokushisa isikhathi esithile, izinga lokushisa (inani le-PV) elikalwa futhi eliboniswa imitha lihluke kakhulu ekushiseni kwangempela kwesici sokushisa (isibonelo, izinga lokushisa langempela lesici sokushisa ngu-200 ° C; kuyilapho imitha ibonisa 230°C noma 180°C)

Lapho uhlangabezana nephutha elinjalo, qala uhlole ukuthi indawo othintana nayo phakathi kwe-temperature probe ne-heater body ikhululekile kanye nokunye ukuthintana okungalungile, ukuthi ukukhethwa kwendawo yokukala izinga lokushisa kulungile, nokuthi ukucaciswa kwenzwa yezinga lokushisa kuyahambisana yini imininingwane yokufaka yesilawuli sezinga lokushisa (njengemitha yokulawula izinga lokushisa).Okokufaka kwe-thermocouple yohlobo lwe-K, futhi i-thermocouple yohlobo lwe-J ifakwe esizeni ukukala izinga lokushisa).

4. Iwindi le-PV lensimbi libonisa izinhlamvu ze-HHH noma ze-LLL.

Uma kuhlangatshezwana nephutha elinjalo, kusho ukuthi isignali elinganiswa ithuluzi ayijwayelekile (i-LLL iboniswa lapho izinga lokushisa elilinganiswa ngethuluzi lingaphansi kuka--19°C, futhi i-HHH iboniswa uma izinga lokushisa lingaphezulu kuka-849°C. ).

Isixazululo: Uma inzwa yezinga lokushisa iyi-thermocouple, ungakwazi ukususa inzwa futhi ufinyeze ngokuqondile amatheminali okokufaka we-thermocouple (amatheminali 8 no-9) wethuluzi ngezintambo.℃), inkinga isenzwa yokushisa, sebenzisa ithuluzi le-multimeter ukuze uthole ukuthi ingabe inzwa yezinga lokushisa (thermocouple noma PT100 thermal resistance) inomjikelezo ovulekile (intambo ephukile), noma ngabe intambo yenzwa ixhunywe ngokuhlehlayo noma ngokungalungile, noma inzwa. imininingwane ayihambisani nethuluzi.

Uma izinkinga ezingenhla ziqedwa, isifunda sokulinganisa izinga lokushisa sangaphakathi sensimbi singashiswa ngenxa yokuvuza kwenzwa.

5. Ukulawula akulawuleki, izinga lokushisa lidlula inani elibekiwe, futhi izinga lokushisa belilokhu likhuphuka.

Lapho uhlangabezana nephutha elinjalo, qala uhlole ukuthi isibani se-OUT semitha sivuliwe yini ngalesi sikhathi, futhi usebenzise ububanzi be-voltage ye-DC "ye-multimeter" ukuze ulinganise ukuthi ingabe amatheminali 3rd kanye ne-4th emitha anokukhipha okungu-12VDC.Uma ukukhanya kuvaliwe, amatheminali 3 kanye no-4 nawo awanakho okukhiphayo okungu-12VDC.Kubonisa ukuthi inkinga ilele kudivayisi yokulawula yesici sokushisa (njengokuthi; i-AC contactor, i-solid state relay, i-relay, njll.).

Isixazululo: Hlola idivayisi yokulawula ngokushesha ukuze uthole ukuthintana okufushane, okunganqamuki, uxhumano lwesekethe olungalungile, njll.
