Mitundu ya owongolera kutentha kwa nkhungu amagawidwa molingana ndi madzi otengera kutentha (madzi kapena mafuta otengera kutentha) omwe amagwiritsidwa ntchito.Ndi makina otenthetsera nkhungu onyamula madzi, kutentha kwambiri komwe kumatuluka nthawi zambiri kumakhala 95 ℃.Chowongolera kutentha kwa nkhungu chonyamula mafuta chimagwiritsidwa ntchito nthawi zina pomwe kutentha kogwira ntchito ndi ≥150 ℃.Nthawi zonse, makina otentha a nkhungu okhala ndi kutentha kwa tanki yamadzi otseguka ndi oyenera makina otenthetsera madzi kapena makina otenthetsera mafuta, ndipo kutentha kwakukulu ndi 90 ℃ mpaka 150 ℃.Makhalidwe akuluakulu a mtundu uwu wa makina otentha a nkhungu ndi mapangidwe osavuta komanso mtengo wachuma.Pamaziko a makina amtunduwu, makina otenthetsera kutentha kwa madzi amachokera.Kutentha kwake kololedwa ndi 160 ℃ kapena kupitilira apo.Chifukwa kutentha madutsidwe madzi ndi apamwamba kuposa mafuta pa kutentha yomweyo pamene kutentha ndi apamwamba kuposa 90 ℃.Zabwino kwambiri, kotero makinawa ali ndi luso lapadera logwira ntchito kutentha kwambiri.Kuphatikiza pa chachiwiri, palinso chowongolera kutentha kwa nkhungu yokakamiza.Pazifukwa zachitetezo, chowongolera kutentha kwa nkhunguchi chimapangidwa kuti chizigwira ntchito kutentha pamwamba pa 150 ° C ndipo chimagwiritsa ntchito mafuta otengera kutentha.Pofuna kupewa mafuta mu chotenthetsera cha makina otentha a nkhungu kuti asatenthedwe, makinawo amagwiritsa ntchito njira yopopera yokakamiza, ndipo chotenthetseracho chimapangidwa ndi machubu angapo odzaza ndi zinthu zotenthetsera zotenthetsera kuti zisokoneze.
Yang'anirani kusagwirizana kwa kutentha mu nkhungu, zomwe zimagwirizananso ndi nthawi ya jekeseni.Pambuyo pa jekeseni, kutentha kwa patsekeke kumakwera pamwamba kwambiri, pamene kutentha kotentha kumagunda khoma lozizira la patsekeke, kutentha kumatsikira pansi kwambiri pamene gawolo likuchotsedwa.Ntchito ya makina otentha a nkhungu ndi kusunga kutentha kosalekeza pakati pa θ2min ndi θ2max, ndiko kuti, kuteteza kusiyana kwa kutentha Δθw kusinthasintha mmwamba ndi pansi panthawi yopanga kapena kusiyana.Njira zowongolera zotsatirazi ndizoyenera kuwongolera kutentha kwa nkhungu: Kuwongolera kutentha kwamadzi ndi njira yomwe imagwiritsidwa ntchito kwambiri, ndipo kuwongolera kulondola kumatha kukwaniritsa zofunikira pazochitika zambiri.Pogwiritsa ntchito njirayi, kutentha komwe kumawonetsedwa mu wolamulira sikumagwirizana ndi kutentha kwa nkhungu;kutentha kwa nkhungu kumasinthasintha kwambiri, ndipo zinthu zotentha zomwe zimakhudza nkhungu sizimayesedwa mwachindunji ndikulipidwa.Zinthu izi zimaphatikizapo kusintha kwa jekeseni, kuthamanga kwa jekeseni, kutentha kwa kutentha ndi kutentha kwa chipinda .Chachiwiri ndikuwongolera mwachindunji kutentha kwa nkhungu.
Njirayi ndikuyika sensa ya kutentha mkati mwa nkhungu, yomwe imagwiritsidwa ntchito pokhapokha ngati kuwongolera kutentha kwa nkhungu kumakhala kokwanira.Zomwe zikuluzikulu za kutentha kwa nkhungu zimaphatikizapo: kutentha komwe kumayikidwa ndi wolamulira kumagwirizana ndi kutentha kwa nkhungu;zinthu zotentha zomwe zimakhudza nkhungu zimatha kuyeza mwachindunji ndikulipidwa.Muzochitika zachilendo, kukhazikika kwa kutentha kwa nkhungu kuli bwino kusiyana ndi kulamulira kutentha kwamadzimadzi.Komanso, nkhungu kutentha ulamuliro ali repeatability bwino mu ulamuliro kupanga ndondomeko.Chachitatu ndi kulamulira pamodzi.Kuwongolera kophatikizana ndikuphatikizana kwa njira zomwe zili pamwambazi, zimatha kuwongolera kutentha kwamadzimadzi ndi nkhungu nthawi yomweyo.Pakuwongolera pamodzi, malo a sensor kutentha mu nkhungu ndi ofunika kwambiri.Poyika chojambulira cha kutentha, mawonekedwe, mawonekedwe, ndi malo a njira yozizira ziyenera kuganiziridwa.Kuphatikiza apo, sensa ya kutentha iyenera kuyikidwa pamalo omwe amathandizira kwambiri pamtundu wa jekeseni wopangidwa ndi magawo.
Pali njira zambiri zolumikizira makina otenthetsera nkhungu imodzi kapena zingapo ku chowongolera makina ojambulira.Kuchokera pamalingaliro a operability, kudalirika ndi kutsutsa kusokoneza, ndi bwino kugwiritsa ntchito mawonekedwe a digito, monga RS485.Zambiri zitha kusamutsidwa pakati pa gawo lowongolera ndi makina opangira jakisoni kudzera pamapulogalamu.Makina otentha a nkhungu amathanso kuwongoleredwa zokha.Kukonzekera kwa makina otenthetsera nkhungu ndi kasinthidwe ka makina otenthetsera nkhungu omwe amagwiritsidwa ntchito ayenera kuweruzidwa momveka bwino molingana ndi zinthu zomwe ziyenera kukonzedwa, kulemera kwa nkhungu, nthawi yofunikira yowotchera komanso zokolola kg/h.Pogwiritsa ntchito mafuta otumizira kutentha, wogwira ntchitoyo ayenera kutsatira malamulo otetezera otere: Osayika chowongolera kutentha kwa nkhungu pafupi ndi ng'anjo yotentha;gwiritsani ntchito mapaipi oletsa kutayikira kapena mapaipi olimba okhala ndi kutentha ndi kukana kukakamiza;kuyang'ana nthawi zonse Kutentha kulamulira kuzungulira nkhungu kutentha Mtsogoleri, ngati pali kutayikira kwa mfundo ndi zisamere pachakudya, ndipo ngati ntchito ndi yachibadwa;kusintha nthawi zonse kwa mafuta otumizira kutentha;mafuta opangira opangira ayenera kugwiritsidwa ntchito, omwe amakhala ndi kukhazikika kwamafuta abwino komanso chizolowezi chochepa chophika.
Pogwiritsa ntchito makina opangira kutentha kwa nkhungu, ndikofunikira kwambiri kusankha madzi otengera kutentha oyenera.Kugwiritsa ntchito madzi ngati madzi otumizira kutentha ndikosavuta, koyera, komanso kosavuta kugwiritsa ntchito.Magawo owongolera kutentha akatuluka, madzi otuluka amatha kuthamangitsidwa ku ngalande.Komabe, madzi omwe amagwiritsidwa ntchito ngati madzi otumizira kutentha amakhala ndi zovuta: madzi otentha amakhala ochepa;malingana ndi momwe madzi amapangidwira, amatha kuwononga ndi kuchepetsedwa, zomwe zimapangitsa kuti pakhale kutaya mphamvu komanso kuchepa kwa kutentha kwapakati pa nkhungu ndi madzi, ndi zina zotero.Mukamagwiritsa ntchito madzi ngati madzi otumizira kutentha, njira zotsatirazi ziyenera kuganiziridwa: konzekerani dera loyendetsa kutentha ndi anti-corrosion agent;gwiritsani ntchito fyuluta musanalowe madzi;nthawi zonse muzitsuka makina otentha a madzi ndi nkhungu ndi chochotsa dzimbiri.Palibe kuipa kwa madzi mukamagwiritsa ntchito mafuta otumizira kutentha.Mafuta ali ndi malo otentha kwambiri, ndipo amatha kugwiritsidwa ntchito pa kutentha kwapamwamba kuposa 300 ° C kapena kupitirira apo, koma kutentha kwa mafuta otumizira kutentha ndi 1/3 yokha ya madzi, kotero makina otentha a mafuta sali ambiri. amagwiritsidwa ntchito popanga jekeseni ngati makina otenthetsera madzi.
