I-Industrial customized 380V 400V kawoyela ongahluziwe wepayipi lokushisisa ipayipi likagesi

I-Industrial customized 380V 400V kawoyela ongahluziwe kawoyela wokushisisa ipayipi lokushisisa isithombe esifakiwe

Incazelo emfushane:

Izishisi zamapayipi kagesi zisebenza kahle kakhulu futhi zonga amandla emishini yokushisisa efakwe ngaphambi kwempahla yokubamba impahla. Iguqula ngokuqondile amandla kagesi abe amandla ashisayo ukushisisa izinto ezigeleza epayipini, njengowoyela osindayo, itiyela, uwoyela ohlanzekile namanye amafutha kaphethiloli, ngendlela eqondile nesheshayo. Le ndlela yokushisa eqondile inciphisa ukulahlekelwa kwenqubo yokudlulisa amandla, okwenza izinto ezibonakalayo zifinyelele ngokushesha izinga lokushisa elidingekayo ekuhambeni kwenqubo elandelayo (njengemijikelezo yezinga lokushisa eliphezulu), ngaleyo ndlela ithuthukise kakhulu ukusebenza kahle kwesistimu futhi ekugcineni ifinyelele umgomo wokongiwa kwamandla kanye nokunciphisa ukusetshenziswa.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Isingeniso Somkhiqizo

Isifudumezi sepayipi likawoyela ongahluziwe siyimishini ekhethekile esebenzisa amandla kagesi ukushisisa ngokuqondile noma ngokungaqondile uwoyela ongahluziwe emapayipini. Isetshenziswa kakhulu ukuxazulula izinkinga zokwanda kwe-viscosity, ukuwohloka kokugeleza, ngisho nokuvaleka kwamapayipi okubangelwa ukwehla kwezinga lokushisa ngesikhathi sokuthuthwa kwamapayipi kawoyela ongahluziwe. Uma kuqhathaniswa nezindlela zokushisa zendabuko ezifana nokulandela umusi kanye nokujikeleza kwamanzi ashisayo, ukufudumeza kukagesi kunezinzuzo ezibalulekile njengokusebenza kahle okuphezulu, ukunemba, ubungane bemvelo, kanye nokufakwa nokugcinwa okulula uma kuqhathaniswa. Ifaneleka ngokukhethekile ezokuthutha ezihamba ibanga elide, izinga lokushisa eliphansi le-ambient, izinto zokuhamba ngezikhathi ezithile, noma izikhathi ezinezidingo eziqinile zokulawula izinga lokushisa.

Isimiso sokusebenza

PI-ipeline heater kagesi iyithuluzi elisebenzisa amandla kagesi ukuze liwaguqule libe amandla ashisayo okufudumeza okudingayo. Ngesikhathi sokusebenza, uketshezi olunezinga lokushisa eliphansi lungena endaweni yalo ngaphansi kwengcindezi, lugeleze eziteshini ezithile zokushintshanisa ukushisa ngaphakathi komkhumbi wokushisisa kagesi, futhi lulandela indlela eklanywe ngokusekelwe ezimisweni ze-thermodynamics eziwuketshezi, zithwala amandla okushisa aphakeme okushisa akhiqizwa izinto zokushisisa zikagesi, ngaleyo ndlela andise izinga lokushisa lendawo eshisisayo I-outlet ye-heater kagesi ithola okuphakathi okudingekayo ngenqubo yokushisa ephezulu. Isistimu yokulawula yangaphakathi ye-heater kagesi ilawula ngokuzenzakalelayo amandla okukhishwa kwe-heater ngokusho kwesignali yenzwa yokushisa ekuphumeni, ukugcina izinga lokushisa elilinganayo le-medium at outlet; lapho into yokushisisa ishisa ngokweqile, idivayisi yokuvikela ngaphezu kwesici sokushisa inqamula ngokushesha amandla okushisa, ivimbele okokushisisa ekushiseni ngokweqile, okubangela i-coke, ukuwohloka, kanye ne-carbonization, kanye nezimo ezinzima, okubangela ukuthi isici sokushisisa sishise, sinwebe ngempumelelo impilo yesevisi ye-heater kagesi.

Umdwebo wenqubo we-heater yepayipi eliwuketshezi

Imininingwane yomkhiqizo iyaboniswa

1.Ukuguqulwa kukagesi: umthombo wamandla wangaphandle (imvamisa i-AC yezimboni) ufakwa ohlelweni lokulawula i-heater.

2.Ukuguqulwa kwe-thermal kagesi: Amandla kagesi aguqulwa abe amandla ashisayo ngokusebenzisa izakhi zokushisa zikagesi ezakhelwe ngaphakathi.

3.Ikhabhinethi yokulawula: Ukuqapha ngesikhathi sangempela izinga lokushisa likawoyela ongahluziwe ngezinzwa zokushisa ezifakwe kumapayipi (njenge-PT100 thermistor noma uhlobo lwe-thermocouple yohlobo lwe-K), kanye nempendulo yamasignali kusilawuli sezinga lokushisa. Isilawuli silungisa ngobuhlakani amandla anikezwa kusici sokushisisa ugesi ngokusekelwe kumazinga okushisa okuqondisiwe (ngokuvamile atholwa nge-thyristor, i-solid-state relay, njll. ngokulawula ukucima noma ukulawula amandla), ukuzuza ukugcinwa kwezinga lokushisa okunembayo nokuzinzile.

Uhlolojikelele lwesicelo sesimo sokusebenza

1) Uhlolojikelele lwepayipi lokushisisa indle likagesi

I-heater kagesi iwuhlobo lwemishini esetshenziswa kakhulu ukufudumeza indle kuphrojekthi yokuhlanza indle. I-heater kagesi iguqula amandla kagesi abe amandla okushisa ukuze ibone umphumela wokushisa wepayipi lokufudumeza indle futhi ithuthukise ukusebenza kahle kanye nekhwalithi yenqubo yokuhlanza indle.

2) Isimiso sokusebenza se-heater kagesi yepayipi yokufudumeza indle

Isimiso sokusebenza se-heater kagesi epayipini lokushisa indle singahlukaniswa zibe izingxenye ezimbili: ukuguqulwa kwamandla kagesi nokudlulisa ukushisa.

1. Ukuguqulwa kwamandla kagesi

Ngemuva kokuthi ucingo lokumelana ku-heater kagesi luxhunywe ekunikezeni amandla, okwamanje ngokusebenzisa ucingo lokumelana kuzokhiqiza ukulahlekelwa kwamandla, okuguqulwa kube amandla okushisa, ukushisa i-heater ngokwayo. Ukushisa kwendawo yokushisa kuyanda ngokunyuka kwamandla, futhi ekugcineni amandla okushisa okushisa adluliselwa kumbhobho wokuthuthwa kwendle odinga ukushiswa.

2. Ukushisa kokushisa

I-heater kagesi idlulisela amandla okushisa ukusuka ebusweni be-heater kuya ebusweni bepayipi, bese kancane kancane idlulisa odongeni lwepayipi kumfucumfucu wepayipi. Inqubo yokushisa ukushisa ingachazwa nge-equation conduction equation, futhi izici zayo eziyinhloko ezithonya zihlanganisa impahla yepayipi, ukushuba kodonga lwamapayipi, ukuqhutshwa kwe-thermal yokudlulisa ukushisa okuphakathi, njll.

3) Isifinyezo

I-heater kagesi iguqula amandla kagesi abe amandla okushisa ukuze kubonakale umphumela wokushisa wepayipi lokushisisa indle. Isimiso sayo sokusebenza sihlanganisa izingxenye ezimbili: ukuguqulwa kwamandla kagesi kanye nokudluliswa kokushisa okushisayo, lapho ukudluliswa kokushisa okushisayo kunezici eziningi ezithonya. Ezenzweni ezisebenzayo, i-heater kagesi efanelekile kufanele ikhethwe ngokuvumelana nesimo sangempela sepayipi yokufudumeza, futhi ukugcinwa okunengqondo kufanele kwenziwe.

Izici Zomkhiqizo

1.Amandla kagesi aguqulwa ngokuqondile abe amandla ashisayo, nokusebenza kahle kokushisa okuphezulu (>95%), okuhambisana nokufaka kahle, okuholela ekulahlekeni kwamandla okuncane. Ukulawula izinga lokushisa okunembile ukugwema ukushisa ngokweqile nokumosha amandla.

2.Ukulawula izinga lokushisa okunembile: Isivinini sokuphendula ngokushesha, ukunemba kokulawula izinga lokushisa eliphezulu (kufika ku-± 1 ° C), kungahlangabezana kahle nezidingo zenqubo.

3.Inobungani nemvelo futhi ihlanzekile: akukho nqubo yokusha, akukho ntuthu noma ukukhishwa kwemfucuza, ukusebenza ngokuthula.

I-4.Idizayini eguquguqukayo: Ingaklanywa ngezindlela ezihlukahlukene, ubukhulu, namandla ukuze ifake amapayipi anobubanzi obuhlukahlukene, ubude, nezikhombisi-ndlela eziyinkimbinkimbi.

I-5.Izinga eliphezulu lokuzenzekelayo: kulula ukufeza ukuqapha okukude, ukulawula okuzenzakalelayo, nokuxilongwa kwephutha.

Ukusebenza okuphephile (ngaphansi kwedizayini ephusile): Awekho amalangabi avulekile (ukuphepha kwangaphakathi noma umklamo wokuvikela ukuqhuma ongasetshenziswa ezindaweni eziyingozi), ayikho ingozi yesitimu esinomfutho ophezulu noma ukuvuza kwamanzi ashisayo.

Isicelo somkhiqizo

I-heater yamapayipi isetshenziswa kakhulu endaweni yasemkhathini, embonini yezikhali, embonini yamakhemikhali nasemakolishi nasemanyuvesi nakweminye ilabhorethri eminingi yocwaningo nokukhiqiza yesayensi. Ifaneleka ngokukhethekile ukulawulwa kwezinga lokushisa okuzenzakalelayo kanye nokugeleza okukhulu kokushisa okuphezulu okuhlanganisiwe uhlelo kanye nokuhlolwa kwesesekeli, indawo yokushisa yomkhiqizo ayi-conductive, ayishisi, ayiqhumi, ayikho ukugqwala kwamakhemikhali, akukho ukungcola, iphephile futhi inokwethenjelwa, futhi indawo yokushisa iyashesha (siyalawuleka).
