I-Industrial electric pipeline heater eyenziwe ngokwezifiso yokushisisa amanzi

Ihitha yepayipi kagesi eyenziwe ngokwezifiso yokushisisa amanzi Isithombe esifakiwe

Incazelo emfushane:

Ipayipi lokujikeleza kwethangi lamanzi i-heater kagesi iwuhlobo lwemishini yokonga amandla eshisisa kuqala impahla, efakwa ngaphambi kwempahla ebonakalayo ukuze ibone ukushisa okuqondile kwento, ukuze ikwazi ukushiswa emjikelezweni wokushisa okuphezulu, futhi ekugcineni ifinyelele inhloso yokonga amandla. Isetshenziswa kakhulu ekushiseni kwangaphambili kwamafutha asindayo, i-asphalt, uwoyela ohlanzekile namanye amafutha kaphethiloli. I-heater yamapayipi yakhiwe izingxenye ezimbili: umzimba kanye nesistimu yokulawula. Isici sokushisa senziwe ngepayipi lensimbi engagqwali njengomkhono wokuvikela, i-high-temperature resistance alloy wire, i-crystalline magnesium oxide powder, eyakhiwe inqubo yokucindezela. Ingxenye yokulawula yakhiwe isekethe yedijithali ethuthukisiwe, i-trigger yesekethe ehlanganisiwe, i-high reverse voltage thyristor kanye nezinye izikali zokushisa ezilungisekayo kanye nesistimu yokushisa engaguquki ukuze kuqinisekiswe ukusebenza okuvamile kwe-heater kagesi.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

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

Isici sokushisisa sisebenzisa i-nickel chromium alloy electric heat wire njengento yokufudumeza, egcwele ukuhlanzeka okuphezulu kwe-magnesium oxide powder insulation kanye nongqimba lwe-thermal conductivity, futhi ungqimba lwangaphandle lugoqwe ngensimbi engagqwali (304/316L noma abanye) noma i-carbon steel sheath, enokumelana nokugqwala nezici zokumelana nezikali.

Isici sokushisa samukela idizayini ye-tubular, esekela ukufakwa okuqondile kumapayipi noma ukushisisa okusheshayo kwendawo egelezayo ngoxhumo lwe-flange.

Izingxenye ezihlanganisiwe, uxhumano lwe-flange: i-flange yensimbi engagqwali evamile, ehambisana nobubanzi bepayipi ye-DN80-DN500, isekela ukufakwa okusheshayo nokugcinwa kokuvala uphawu.

Isendlalelo se-insulation: Ungqimba lwangaphandle lugoqwe nge-aluminium silicate ukotini noma impahla ye-rock wool ukunciphisa ukulahlekelwa ukushisa, futhi ukusebenza kahle kokushisa kungafinyelela ngaphezu kwama-90%.

Isistimu yokulawula izinga lokushisa: I-PT100 edidiyelwe noma i-thermocouple yohlobo lwe-K, ehlanganiswe nemojuli ye-thyristor/solid-state relay ukuze kuzuzwe ukulungiswa okunembayo okungu-± 1 ℃.

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.

Isicelo somkhiqizo

I-heater yamapayipi isetshenziswa kabanzi ku-aerospace, embonini yezikhali, embonini yamakhemikhali nasemakolishi nasemanyuvesi kanye nezinye ilabhorethri yocwaningo nokukhiqiza eminingi 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).

Imboni yokufaka i-heater yamapayipi anguketshezi

Izici Zomkhiqizo

1.Isebenza kahle futhi iyonga amandla: Ngokusebenza kahle kokushisa okungaphezu kuka-95%, amandla kagesi aguqulwa ngokuqondile abe amandla ashisayo ngaphandle kokulahlekelwa okuphakathi. Kungalawulwa izinga lokushisa ezindaweni noma kusetshenzwe ngezikhathi ezihlukene ukuze kuncishiswe ukusetshenziswa kwamandla.

2.Iphephile futhi inokwethenjelwa: Izindlela zokuvikela eziningi zokugwema izingozi ezifana nokusha okomile nokuvuza kukagesi.

3.Ukufakwa okuguquguqukayo: Isekela ukufakwa okuvundlile noma okuqondile ukuze kuhambisane nezakhiwo zamapayipi ezahlukene. Idizayini ye-modular isiza ukunwetshwa noma ukushintshwa kwezingxenye.

4.Inobungani bemvelo futhi ayingcolisi: Akukho kukhishwa kwesisi esivuthayo, esihlangabezana nezidingo zokuvikela imvelo.
