Intshayelelo yesilawuli sobushushu kunye nokufuma

Isishwankathelo

Ulawulo lobushushu kunye nokufuma lusekwe kwi-microcomputer ye-single-chip ephambili njengondoqo wolawulo, kwaye yamkela iqondo eliphezulu leqondo lobushushu kunye nezinzwa zokufuma, ezinokulinganisa nokulawula imiqondiso yobushushu kunye nokufuma ngaxeshanye, kwaye ibone umboniso wedijithali wolwelo. .Umda osezantsi umiselwe kwaye uboniswe, ukwenzela ukuba isixhobo sinokuqala ngokuzenzekelayo i-fan okanye i-heater ngokwemeko ye-site, kwaye ilungelelanise ngokuzenzekelayo ukushisa kwangempela kunye nomswakama wendawo elinganisiweyo.

Wumgaqo wokusebenza

Isilawuli seqondo lokushisa kunye nomswakama ikakhulu siqulunqwe ngamalungu amathathu: inzwa, isilawuli kunye nesifudumezi.Umgaqo wayo wokusebenza umi ngolu hlobo lulandelayo: inzwa ibona ulwazi lweqondo lokushisa kunye nomswakama kwibhokisi, kwaye idlulisele kumlawuli ukuhlalutya kunye nokucutshungulwa: xa iqondo lokushisa kunye nomswakama kwibhokisi lifikelela okanye Xa ixabiso le-preset ligqithiswa, i-relay contact. kwisilawuli sivaliwe, i-heater inikwe amandla kwaye iqala ukusebenza, ukufudumeza okanye ukuvuthela umoya kwibhokisi;emva kwexesha elithile, iqondo lobushushu okanye ukufuma kwibhokisi ukude kwixabiso elimisiweyo, kunye Abafowunelwa relay kwisixhobo evulekileyo, ukufudumeza okanye ukuvuthela ayeke.

Aisicelo

Iimveliso zolawulo lobushushu kunye nokufuma zisetyenziselwa ukulungiswa kunye nokulawula ubushushu bangaphakathi kunye nokufuma kweekhabhathi zokutshintsha kombane ophakathi kunye nophezulu, iibhokisi ze-terminal, iikhabhathi zenethiwekhi yeringi, iibhokisi zebhokisi kunye nezinye izixhobo.Inokuthintela ngokufanelekileyo ukusilela kwezixhobo ezibangelwa ubushushu obuphantsi kunye nobushushu obuphezulu, kunye neengozi ze-creepage kunye ne-flashover ezibangelwa ngumswakama okanye ukuxinana.

Ukuhlelwa

Izilawuli zobushushu kunye nokufuma zahlulwe ikakhulu zibe ziindidi ezimbini: uthotho oluqhelekileyo kunye nothotho olukrelekrele.

Ubushushu obuqhelekileyo kunye nesilawuli sokufuma: Yenziwe ngeqondo lobushushu lepolymer elingeniswe ngaphandle kunye nenzwa yokufuma, idityaniswe nesekethe ye-analog ezinzileyo kunye nokutshintsha itekhnoloji yonikezelo lwamandla.

Ubushushu obukrelekrele kunye nesilawuli sokufuma: Ibonisa amaxabiso obushushu kunye nokufuma ngendlela yeetyhubhu zedijithali, kwaye ine-heater, isalathiso sempazamo yoluvo, kunye nemisebenzi yothumelo.Isixhobo sidibanisa umlinganiselo, umboniso, ulawulo kunye nonxibelelwano.Inomgangatho ophezulu wokuchaneka kunye noluhlu lomlinganiselo obanzi.Umlinganiselo wobushushu kunye nokufuma kunye nesixhobo sokulawula esifanelekileyo kumashishini ahlukeneyo kunye namasimi.

Isikhokelo sokhetho

Iqondo lokushisa elihlakaniphile kunye nomlawuli womswakama unokulinganisa kumanqaku amaninzi ngexesha elinye, kwaye ulawule ukushisa kunye nomswakama wendalo kwiindawo ezininzi.Olu lwazi lulandelayo kufuneka lufakwe xa u-odola: imodeli yemveliso, umbane oncedisayo, iiparamitha zokulawula, ubude bekhebula, i-heater.

Mulungiso

Ukugcinwa kobushushu kunye nesilawuli sokufuma:

1. Njalo khangela imeko yokusebenza yomlawuli.

2. Khangela ukuba imeko yokusebenza yefriji iqhelekile (ukuba kukho i-fluoride encinci, i-fluoride kufuneka izaliswe kwakhona ngexesha).

3. Jonga ukuba unikezelo lwamanzi etephini lwanele na.Ukuba akukho manzi, cima iswitshi ye-humidification ngexesha ukuze ugweme ukutshisa i-humidifier.

4. Qwalasela iintambo kunye nezifudumezi ukuba azivuzi na.

5. Khangela ukuba intloko yokutshiza ivalekile na.

6. Qaphela ukuba i-humidification yepompo yamanzi iya kuyeka ukujikeleza ngenxa ye-sediments yamanzi engasetyenziswanga ixesha elide, kwaye iguqule i-fan blade kwi-toggle port ukuze ijikeleze.

Imibandela efuna ingqalelo

1. "Ukuhlolwa kwansuku zonke" kwenyanga kufuneka kuhlolisise ukunyaniseka kwesilawuli seqondo lokushisa kunye nomswakama, kwaye uxele ingxaki ngexesha ukuze uyigcine isesimweni esihle.Umgama phakathi kombhobho wokufudumeza kunye nekhebula kunye nocingo akukho ngaphantsi kwe-2cm;

2. Izilawuli zeqondo lokushisa kunye nomswakama wazo zonke iibhokisi ze-terminal kunye neebhokisi zendlela kufuneka zibekwe kwindawo yokufaka, ukwenzela ukuba ubushushu kunye nomswakama ulawulwe ngaphakathi kwinqanaba eliqhelekileyo.

3. Ekubeni iqondo lokushisa lokubonisa idijithali kunye nomlawuli womswakama akanalo umsebenzi wememori, rhoqo xa umbane ucinyiwe, izicwangciso zefektri ziya kubuyiselwa emva kokuba amandla avuliwe kwakhona, kwaye izicwangciso kufuneka zihlaziywe.

4. Gwema ukusebenzisa isilawuli sobushushu kunye nokufuma kwindawo enothuli oluphezulu.Zama ukufaka umatshini kwindawo evulekileyo.Ukuba igumbi elilinganiswe ngumatshini likhulu, ukwandisa inani leqondo lokushisa kunye nezinzwa zokufuma.

Tukulungisa ingxaki

Iimpazamo eziqhelekileyo zezilawuli zobushushu ezikrelekrele:

1. Emva kokufudumeza ixesha elithile, iqondo lokushisa alitshintshi.Hlala ubonisa iqondo lobushushu lendawo kwindawo (elifana nobushushu begumbi 25°C)

Xa udibana nesiphoso esinjalo, jonga kuqala ukuba ixabiso lexabiso le-SV lisetyenzisiwe, ingaba isibane sesibonisi se-OUT semitha sivuliwe, kwaye usebenzise "i-multimeter" ukulinganisa ukuba i-terminal ye-3 neye-4 yemitha inemveliso ye-12VDC.Ukuba ukukhanya kuvuliwe, iitheminali 3 kunye ne-4 nazo zinemveliso ye-12VDC.Kuthetha ukuba ingxaki ilele kwisixhobo solawulo somzimba wokufudumeza (njenge-AC contactor, i-slid state relay, i-relay, njl. njl.), khangela ukuba isixhobo sokulawula sinesekhethi evulekileyo kunye nokuba iinkcukacha zesixhobo ziphosakele (ezifana ne Isixhobo se-380V kwisekethe ye-220), Ingaba umgca uxhunyiwe ngokungalunganga, njl. Ukongeza, khangela ukuba i-sensor ifutshane-ijikelezwe (xa i-thermocouple ifutshane, imitha ihlala ibonisa ukushisa kwegumbi).

2. Emva kokufudumeza ixesha elithile, umboniso wokushisa uyancipha kwaye uhla

Xa udibana nesiphoso esinjalo, i-polarities ekhangayo kunye nembi ye-sensor iguqulwa ngokubanzi.Ngeli xesha, kufuneka ujonge i-input terminal wiring ye-sensor yesixhobo (i-thermocouple: i-8 iqhagamshelwe kwisibonda esilungileyo, kwaye i-9 idibaniswe kwipali engafanelekanga; I-PT100 ukuxhathisa kwe-thermal: ?8 ixhunywe kwintambo yombala omnye, I-9 kunye ne-10 idibene neentambo ezimbini zombala ofanayo).

3. Emva kokufudumeza ixesha elithile, ixabiso leqondo lokushisa (ixabiso le-PV) elilinganiswe kwaye libonakaliswe imitha lihluke kakhulu kwiqondo lokushisa langempela lezinto zokufudumala (umzekelo, iqondo lokushisa langempela le-200 ° C; ngelixa imitha ibonisa 230 °C okanye 180 °C)

Xa udibana nesiphoso esinjalo, jonga kuqala ukuba indawo yokunxibelelana phakathi kweprobe yobushushu kunye nomzimba wokufudumeza ikhululekile kunye nolunye unxibelelwano olungalunganga, ukuba ngaba ukukhethwa kwendawo yokulinganisa ubushushu kuchanekile, kwaye nokuba ukucaciswa kwesivamvo sobushushu kuyahambelana inkcazo yegalelo lomlawuli weqondo lokushisa (njengemitha yokulawula ubushushu).I-K-type thermocouple input, kunye ne-J-type thermocouple ifakwe kwisayithi ukulinganisa ubushushu).

4. Ifestile ye-PV yesixhobo ibonisa iimpawu ze-HHH okanye ze-LLL.

Xa eso siphoso sifunyenwe, kuthetha ukuba isignali elinganiswa nesixhobo ayiqhelekanga (i-LLL iboniswa xa iqondo lokushisa elilinganiswa nesixhobo lingaphantsi kwe -19 ° C, kwaye i-HHH ibonakaliswe xa iqondo lokushisa lingaphezulu kwe-849 ° C. ).

Isisombululo: Ukuba i-sensor yeqondo lokushisa yi-thermocouple, unako ukususa i-sensor kunye ne-short-circuit ngokuthe ngqo i-terminals input terminals (i-terminals 8 kunye ne-9) yesixhobo ngeengcingo.℃), ingxaki ikwi-sensor yeqondo lokushisa, sebenzisa isixhobo se-multimeter ukubona ukuba i-sensor yeqondo lokushisa (i-thermocouple okanye i-PT100 yokumelana ne-thermal) inesekhethi evulekileyo (intambo eyaphukileyo), nokuba i-sensor wire ixhunyiwe ngokuphindaphindiweyo okanye ngokungalunganga, okanye inzwa. iinkcukacha azihambelani nesixhobo.

Ukuba ezi ngxaki zingentla zipheliswe, isiphaluka sokulinganisa ukushisa kwangaphakathi kwesixhobo sinokutshiswa ngenxa yokuvuza kwenzwa.

5. Ulawulo alukwazi ukulawula, ukushisa kudlula ixabiso elimiselweyo, kwaye ukushisa kuye kwanda.

Xa udibana nesiphoso esinjalo, jonga kuqala ukuba ngaba ukukhanya kwe-OUT ye-meter imitha kuvuliwe ngeli xesha, kwaye usebenzise uluhlu lwe-DC voltage ye "multimeter" ukulinganisa ukuba i-terminal ye-3 neyesine yemitha ine-12VDC output.Ukuba isibane sicinyiwe, iitheminali 3 kunye ne-4 azinayo imveliso ye-12VDC.Ibonisa ukuba ingxaki ilele kwisixhobo solawulo sento yokufudumeza (efana ne-AC contactor, i-slid state relay, i-relay, njl.).

Isisombululo: Jonga isixhobo solawulo ngokukhawuleza kwisekethe emfutshane, uqhagamshelwano olungaqhawukiyo, uqhagamshelwano olungalunganga lwesekethe, njl.
