Intshayelelo yeMveliso

Isifudumezi sombhobho we-oyile ekrwada sisixhobo esikhethekileyo esisebenzisa amandla ombane ukutshisa ngokuthe ngqo okanye ngokungathanga ngqo i-oyile ekrwada kwimibhobho. Isetyenziswa ikakhulu ukusombulula iingxaki zokunyuka kwe-viscosity, ukuwohloka kokuhamba, kunye nokuvaleka kwemibhobho okubangelwa kukuhla kwamaqondo obushushu ngexesha lokuthuthwa kwemibhobho yeoli ekrwada. Xa kuthelekiswa neendlela zokufudumeza zemveli ezifana nokulandela umphunga kunye nokujikeleza kwamanzi ashushu, ukufudumeza kombane kuneenzuzo ezibalulekileyo ezifana nokusebenza okuphezulu, ukuchaneka, ubuhlobo bendalo, kunye nofakelo olulula kunye nokugcinwa. Ilungele kakhulu ukuthutha umgama omde, ubushushu obuphantsi be-ambient, ukuthutha okuphakathi, okanye amaxesha aneemfuno ezingqongqo zokulawula ubushushu.

Umgaqo wokusebenza

Pi-ipeline isifudumezi sombane sisixhobo esisebenzisa amandla ombane ukuyiguqula ibe ngamandla obushushu kwizinto ezifuna ukufudumeza. Ngexesha lokusebenza, ubushushu obuphantsi bobushushu obuphakathi bungena kwindawo yayo yokungena phantsi koxinzelelo, buqukuqela kwimijelo ethile yokutshintshiselana kobushushu ngaphakathi kwinqanawa yokufudumeza yombane, kwaye ilandele indlela eyilwe ngokusekwe kwimigaqo ye-thermodynamics ye-fluid, ithatha amandla obushushu obuphezulu obuveliswa ngezinto zokufudumeza zombane, ngaloo ndlela inyusa ubushushu bendawo eshushu. Inkqubo yokulawula yangaphakathi ye-heater yombane ilawula ngokuzenzekelayo amandla okuphuma kwe-heater ngokuhambelana nomqondiso we-sensor sensor kwi-outlet, ukugcina ukushisa okufanayo kwendawo yokuphuma; xa into yokufudumeza igqithisa, isixhobo esizimeleyo sokukhusela isixhobo sokufudumeza ngokukhawuleza sinqumla umbane wokufudumeza, ukuthintela izinto zokufudumeza ekufudumeni, kubangela i-coke, ukuwohloka, kunye ne-carbonization, kunye neemeko ezinzima, ezibangela ukuba into yokufudumeza itshise, ikhulise ngokufanelekileyo ubomi benkonzo ye-heater yombane.

Idayagram yenkqubo yesifudumezi solwelo lombhobho

Iinkcukacha zemveliso zibonisa

I-1.Ukuguqulwa kombane: umthombo wamandla wangaphandle (ngokuqhelekileyo i-AC ye-industrial) igalelo kwinkqubo yokulawula ukufudumala.

I-2.Electric thermal conversion: Amandla ombane aguqulwa abe ngumbane we-thermal ngokusebenzisa izinto zokufudumeza zombane ezakhelwe ngaphakathi.

I-3.Ikhabhinethi yokulawula: Ixesha langempela lokujonga ubushushu be-oyile ekrwada ngokusebenzisa izinzwa zobushushu ezifakwe kwimibhobho (ezifana ne-PT100 thermistor okanye i-K uhlobo lwe-thermocouple), kunye nengxelo yezibonakaliso kumlawuli wokushisa. Umlawuli ulungelelanisa ngokuhlakanipha amandla anikezelweyo kumbane wokufudumeza umbane ngokusekelwe kwiqondo lokushisa elijoliswe kuyo (elidla ngokufezekiswa nge-thyristor, i-solid-state relay, njl. njl

Ushwankathelo lwesicelo semeko yokusebenza

1) Isishwankathelo sombhobho wokufudumeza wombane wamanzi amdaka

Isifudumezi sombane luhlobo lwezixhobo ezisetyenziselwa ukufudumeza ilindle kwiprojekthi yokucoca ugutyulo. Isifudumezi sombane siguqula amandla ombane abe ngamandla obushushu ukuqonda isiphumo sokufudumeza kombhobho wokufudumeza amanzi amdaka kunye nokuphucula ukusebenza kakuhle kunye nomgangatho wenkqubo yokucocwa kwelindle.

2) Umgaqo wokusebenza we-heater yombane wombhobho wokufudumeza wamanzi amdaka

Umgaqo osebenzayo we-heater yombane kumbhobho wokufudumala wamanzi amdaka ungahlulwa ube ngamacandelo amabini: ukuguqulwa kwamandla ombane kunye nokutshintshwa kobushushu.

1. Ukuguqulwa kwamandla ombane

Emva kokuba ucingo lokuchasa kwi-heater yombane ludibaniswe kumandla ombane, i-current through the resistance wire iya kuvelisa ilahleko yamandla, eguqulwa ibe amandla okushisa, ukufudumeza i-heater ngokwayo. Ubushushu bomgangatho wokufudumala buyanda ngokunyuka kwangoku, kwaye ekugqibeleni amandla okushisa omgangatho wokufudumala adluliselwa kumbhobho wamanzi amdaka ofuna ukufudumeza.

2. Ukuqhuba kobushushu

Isifudumezi sombane sidlulisela amandla obushushu ukusuka kumphezulu we-heater ukuya kumphezulu wombhobho, kwaye ngokuthe ngcembe idlulisele kunye nodonga lombhobho ukuya kugutyulo kumbhobho. Inkqubo yokuqhuba ubushushu inokuchazwa nge-equation conduction equation, kwaye izinto zayo eziphambili ezichaphazelayo ziquka izinto zombhobho, ubukhulu bodonga lombhobho, ukuhanjiswa kwe-thermal yokudlulisa ukushisa, njl njl.

3) Isishwankathelo

Isifudumezi sombane siguqula amandla ombane abe ngamandla obushushu ukuqonda isiphumo sokufudumeza kombhobho wokufudumeza amanzi amdaka. Umgaqo wayo wokusebenza uquka iinxalenye ezimbini: ukuguqulwa kwamandla ombane kunye nokutshintshwa kokushisa kwe-thermal, apho ukuhanjiswa kokushisa kwe-thermal kunezinto ezininzi ezichaphazelayo. Kwizicelo eziphathekayo, i-heater yombane efanelekileyo kufuneka ikhethwe ngokwemeko yangempela yombhobho wokufudumeza, kwaye ukugcinwa okufanelekileyo kufuneka kwenziwe.

Iimpawu zeMveliso

I-1.Amandla ombane aguqulwa ngokuthe ngqo kumandla ashushu, kunye nokusebenza kakuhle kwe-thermal (> 95%), edibaniswe ne-insulation efanelekileyo, okubangela ukulahlekelwa kwamandla okuncinci. Ulawulo oluchanekileyo lobushushu ukuphepha ukutshisa kunye nokuchithwa kwamandla.

2.Ulawulo oluchanekileyo lobushushu: Isantya sokuphendula ngokukhawuleza, ukuchaneka kokulawula ubushushu obuphezulu (ukuya kuthi ga kwi-± 1 ° C), sinokuhlangabezana kakuhle neemfuno zenkqubo.

3.I-Environmental friendly and clean: akukho nkqubo yokutsha, akukho msi okanye ukukhutshwa kwenkunkuma, ukusebenza ngokuzolileyo.

Uyilo lwe-4.Flexible: Inokuthi iyilwe kwiimilo ezahlukeneyo, ubungakanani, kunye namandla ukuze kuhlaliswe imibhobho yobubanzi obuhlukeneyo, ubude, kunye nemikhombandlela enzima.

I-5.Izinga eliphezulu lokuzenzekelayo: kulula ukufezekisa ukubeka iliso kude, ulawulo oluzenzekelayo, kunye nokuxilongwa kwempazamo.

Ukusebenza okukhuselekileyo (phantsi koyilo olufanelekileyo): Akukho madangatye avulekileyo (ukhuseleko lwangaphakathi okanye uyilo lokuthintela ugqabhuko-dubulo lunokusetyenziswa kwiindawo ezinobungozi), akukho mngcipheko womphunga woxinzelelo oluphezulu okanye ukuvuza kwamanzi ashushu.

Isicelo semveliso

Isifudumezi sombhobho sisetyenziswa kakhulu kwi-aerospace, ishishini lezixhobo, ishishini lemichiza kunye neekholeji kunye neeyunivesithi kunye nolunye uphando lwesayensi kunye nelebhu yemveliso. Ilungele ngokukodwa ukulawulwa kweqondo lokushisa oluzenzekelayo kunye nokuhamba okukhulu kwenkqubo yokushisa ephezulu edibeneyo kunye novavanyo lwe-accessory, i-medium yokufudumeza yemveliso ayinayo i-conductive, i-non-burning, i-non-explosion, i-chemical corrosion, akukho ukungcola, ikhuselekile kwaye inokwethenjelwa, kwaye indawo yokufudumeza ikhawuleza (iyalawuleka).
