I-heater kawoyela yepayipi

Incazelo emfushane:

I-heater kawoyela yamapayipi iwuhlobo lwemishini yokonga amandla eshisa kuqala impahla, efakwa ngaphambi kwemishini yezinto ezibonakalayo 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

Isimiso sokushisisa uwoyela wepayipi sisekelwe kakhulu ohlelweni lokuguqula amandla kagesi abe ukushisa. Ngokuqondile, i-heater kagesi iqukethe isici sokushisa kagesi, ngokuvamile intambo yokumelana nokushisa okuphezulu, eshisa lapho i-current idlula, futhi ukushisa okubangelwayo kudluliselwa ku-fluid medium, ngaleyo ndlela kushise uketshezi.

I-heater kagesi iphinde ifakwe uhlelo lokulawula, okuhlanganisa izinzwa zokushisa, izilawuli zokushisa zedijithali kanye ne-solid-state relays, okuhlangene kwakha isilinganiso, i-loop yokulawula kanye nokulawula. Inzwa yezinga lokushisa ithola izinga lokushisa lokukhipha uketshezi futhi idlulisele isignali kusilawuli sezinga lokushisa ledijithali, esilungisa ukuphuma kwe-solid state relay ngokuya ngenani lokushisa elimisiwe, bese lilawula amandla e-heater kagesi ukugcina ukuzinza kwezinga lokushisa. we-fluid medium.

Ngaphezu kwalokho, i-heater kagesi ingase futhi ifakwe idivayisi yokuvikela ukushisa ngokweqile ukuvimbela isici sokushisa ekushiseni ngokweqile, ukugwema ukuwohloka okuphakathi nendawo noma ukulimala kwemishini ngenxa yokushisa okuphezulu, ngaleyo ndlela kuthuthukiswe ukuphepha nokuphila kwemishini.

Ukugeleza kokusebenza kwe-heater yephayiphi elinguketshezi

Imininingwane yomkhiqizo iyaboniswa

Umdwebo wemininingwane ye-heater yamapayipi

Uhlolojikelele lwesicelo sesimo sokusebenza

Isimiso sokusebenza se-heater kagesi yamafutha ngokuyinhloko sisekelwe ekushiseni okukhiqizwa yisici sokushisa kagesi, esidluliselwa emafutheni ashisayo, ukuze izinga lokushisa liphakanyiswe, bese ukushisa kudluliselwa kumishini noma inqubo okudingeka ukushisisa ngokusebenzisa uketshezi isigaba kwegazi. Ireferensi eqondile ingaba kanjena:

Isici sokushisisa sikhiqiza ukushisa. Izinto zokushisisa ngogesi (njengamashubhu okushisa kagesi noma izinduku zokushisisa) zikhiqiza ukushisa uma zinikwe amandla.

Amafutha ashisayo adlulisa ukushisa. Isici sokushisa sidlulisela ukushisa emafutheni ashisayo ku-tubing, futhi izinga lokushisa lamafutha ashisayo liyakhuphuka ngemva kokushiswa.

Uhlelo lokulawula izinga lokushisa lulawula umsinga. Isistimu yokulawula izinga lokushisa ithola izinga lokushisa lamafutha ashisayo ngesikhathi sangempela ngenzwa, futhi ilungisa okwamanje ngokuvumelana nezinga lokushisa esethiwe, lilawula isimo sokusebenza sesici sokushisa, futhi igcina izinga lokushisa lamafutha ashisayo lizinzile.

Amafutha okushisa okushisa ajikeleza ukudluliswa kokushisa. Amafutha ashisayo ashisayo ajikeleza ohlelweni ngokusebenzisa ipompo ejikelezayo, edlulisela ukushisa emshinini oshisayo, futhi ngemva kokushisa kukhishwa imishini yokushisa, amafutha ashisayo abuyela ku-heater ukuze ashiswe kabusha.

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 kwesistimu ehlanganisiwe kanye nokuhlolwa kwesesekeli, indawo yokushisa yomkhiqizo ayi-conductive, ayishisi, ayiqhumi, ayikho ukugqwala kwamakhemikhali, akukho ukungcola, iphephile futhi inokwethenjelwa, futhi indawo yokushisa iyashesha (iyalawuleka).
