Umbhobho wokufudumeza ioli

Umbhobho oyile heater Featured Umfanekiso

Inkcazelo emfutshane:

I-oyile ye-pipeline heater luhlobo lwezixhobo zokulondoloza amandla ezifudumeza kwangaphambili izinto, ezifakwe ngaphambi kokuba izixhobo eziphathekayo ziqonde ukufudumeza ngokuthe ngqo kwezinto eziphathekayo, ukwenzela ukuba zifudunyezwe kumjikelezo ophezulu wokushisa, kwaye ekugqibeleni zifezekise injongo yokugcina amandla. Isetyenziswa ngokubanzi kwi-preheating ye-oyile enzima, i-asphalt, ioli ecocekileyo kunye nezinye ioli yeoli. I-heater yombhobho yenziwe ngamacandelo amabini: umzimba kunye nenkqubo yokulawula. Isixhobo sokufudumeza senziwe ngombhobho wensimbi engenasici njengomkhono wokukhusela, ubushushu obuphezulu be-alloy wire, i-crystalline magnesium oxide powder, eyenziwa yinkqubo yoxinzelelo. Icandelo lolawulo liqulunqwe yisekethe yedijithali ephuculweyo, i-trigger yesekethe edibeneyo, i-high reverse voltage thyristor kunye nolunye umlinganiselo wokushisa ohlengahlengiswayo kunye nenkqubo yokushisa rhoqo ukuqinisekisa ukusebenza okuqhelekileyo kwesifudumezi sombane.

Umgaqo wokusebenza

Umgaqo wokufudumeza ioyile yombhobho usekelwe ikakhulu kwinkqubo yokuguqula amandla ombane abe bubushushu. Ngokukodwa, i-heater yombane iqulethe into yokufudumala yombane, ngokuqhelekileyo intambo yokumelana nobushushu obuphezulu, obutshisayo xa umbane udlulayo, kwaye ubushushu obubangelwayo bugqithiselwa kwi-fluid medium, ngaloo ndlela ukufudumala umbane.

Isifudumezi sombane sikwaxhotyiswe ngenkqubo yokulawula, kubandakanywa izinzwa zeqondo lokushisa, izilawuli zeqondo lokushisa kwedijithali kunye ne-solid-state relays, ezihlangeneyo zenza umlinganiselo, ummiselo kunye nokulawula i-loop. Isivamvo seqondo lobushushu sibona ubushushu bombhobho wolwelo kwaye sidlulise umqondiso kumlawuli wobushushu bedijithali, olungisa imveliso ye-relay yesimo esiluqilima ngokwexabiso elibekiweyo lobushushu, kwaye emva koko ulawula amandla obushushu bombane ukugcina uzinzo lobushushu bendawo yolwelo.

Ukongezelela, i-heater yombane inokuxhotyiswa ngesixhobo sokukhusela ubushushu ukukhusela into yokufudumala kwi-overtemperature, ukuphepha ukuchithwa okuphakathi okanye umonakalo wezixhobo ngenxa yokushisa okuphezulu, ngaloo ndlela kuphuculwe ukhuseleko kunye nobomi bezixhobo.

Ushwankathelo lwesicelo semeko yokusebenza

Umgaqo osebenzayo we-oyile yokufudumala yombane usekelwe ikakhulu kubushushu obuveliswa yinto yokufudumala yombane, edluliselwa kwioli ye-thermal, ukwenzela ukuba ukushisa kwayo kuphakanyiswe, kwaye ubushushu budluliselwe kwisixhobo okanye inkqubo efuna ukufudumeza ngokujikeleza kwesigaba solwelo. Isalathiso esithe ngqo singaba ngolu hlobo lulandelayo:

Into yokufudumeza yenza ubushushu. Izinto zokufudumeza zombane (ezifana neetyhubhu zokufudumeza zombane okanye iintonga zokufudumeza) zivelisa ubushushu xa zinikwe amandla.

Ioyile eshushu ihambisa ubushushu. Into yokufudumala idlulisela ukushisa kwioli ye-thermal kwi-tubing, kwaye ukushisa kweoli ye-thermal kuphakama emva kokufudumala.

Inkqubo yokulawula ubushushu ilawula okwangoku. Inkqubo yokulawula ubushushu ibona ubushushu beoyile ye-thermal ngexesha langempela ngokusebenzisa i-sensor, kwaye ilungelelanise okwangoku ngokuhambelana nobushushu obusethiweyo, ilawula imeko yokusebenza kwendawo yokufudumeza, kwaye igcina ubushushu be-oyile ye-thermal buzinzile.

Ioli yokuqhuba ubushushu ijikeleza ukuhanjiswa kobushushu. I-oyile eshushu yokufudumala ijikeleza kwinkqubo ngokusebenzisa ipompo ejikelezayo, idlulisela ukushisa kwisixhobo sokushisa, kwaye emva kokuba ubushushu bukhutshwe ngezixhobo ze-thermal, i-oyile ye-thermal ibuyela kwi-heater ukuze ihlaziywe.

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).
