Namhlanje, masithethe ngeityhubhu yokufudumeza i-oven yomphunga, eyona nto inxulumene ngokuthe ngqo ne-oven yomphunga. Kaloku, umsebenzi ophambili we-oven yomphunga kukupheka ngomphunga, kwaye ukugweba ukuba i-oven yomphunga ilungile okanye ayilunganga kangakanani, isitshixo sisaxhomekeke ekusebenzeni kwetyhubhu yokufudumeza.
Okokuqala, yintoni ityhubhu yokufudumeza i-oven?
Iityhubhu yokufudumeza i-ovenyityhubhu yesinyithi engenamthungo (ityhubhu yesinyithi yekhabhoni, ityhubhu yetitanium, ityhubhu yesinyithi esingenasici, ityhubhu yekopolo) kwintambo yokufudumeza yombane, inxalenye yesithuba izaliswe yi-thermal conductivity elungileyo kunye ne-insulation ye-MgO powder emva kokuba ityhubhu ifinyeziwe, ize icutshungulwe ibe ziimo ezahlukeneyo ezifunekayo ngabasebenzisi.
Iityhubhu yokufudumeza isitovuineempawu zokuphendula ngokukhawuleza kobushushu, ukuchaneka kolawulo lobushushu obuphezulu kunye nokusebenza kakuhle kobushushu obupheleleyo. Ubushushu obuphezulu bokufudumeza buthetha ukuba ubushushu obuphezulu bomsebenzi woyilo lwesifudumezi bunokufikelela kwi-850℃. Umyinge wobushushu obuphakathi, ukuchaneka kolawulo lobushushu obuphezulu.
Kuthekani ngetyhubhu yokufudumeza ye-oven yomphunga?
Ngokubanzi, i-oven yomphunga ineeseti ezintathu zeetyhubhu zokufudumeza, eziphezulu nezisezantsi kunye netyhubhu yokufudumeza engasemva, kwaye uluhlu olupheleleyo lokubhaka ukutya lwenziwa yifeni engasemva.
Izinto zeheater
Umbhobho wokufudumeza we-oven yomphunga wenziwe kakhuluintsimbi engatyiwayo kunye netyhubhu ye-quartz.
Ityhubhu yokufudumeza yeQuartzyinkqubo ekhethekileyo yetyhubhu yeglasi ye-quartz ye-opalescent, enezinto zokuxhathisa njenge-heater, kuba iglasi ye-quartz ye-opalescent inokufunxa phantse lonke ukukhanya okubonakalayo kunye nokukhanya okukufutshane ne-infrared okuvela kwimitha ye-heating wire, kwaye ingayiguqula ibe yimitha ye-infrared ekude.
Iingenelo:ukufudumeza ngokukhawuleza, uzinzo oluhle lobushushu
Iingxaki:kulula ukuba buthathaka, akukho lula ukuyiphinda uyicubungule, akukho lawulo luchanekileyo lobushushu,
Olu hlobo lwetyhubhu yokufudumeza lufanelekile kakhulu kwii-oveni ezincinci.
Ngoku izinto eziphambili zokusebenzisa i-oven yomphunga kwimarike yintsimbi engagqwaliyo. Ngokuyintloko yintsimbi engagqwaliyo ye-301s kunye nentsimbi engagqwaliyo ye-840.
Ityhubhu yokufudumeza yentsimbi engagqwaliyo isetyenziselwa ukufudumeza ulwelo ngokunyanzela i-convection.
Iingenelo:ukumelana nokugqwala, akukho lula ukugqwala, ukumelana nobushushu okuhle, ukhuseleko, iplastiki eqinileyo
Umahluko phakathi komgangatho wezinto zombane zokufudumeza ngentsimbi engagqwaliyo ngokuyintloko ngumahluko kumxholo we-nickel. I-Nickel yinto ebalaseleyo ekwaziyo ukumelana nokugqwala, kwaye ukumelana nokugqwala kunye neempawu zenkqubo yentsimbi engagqwaliyo zinokuphuculwa emva kokudityaniswa kwe-chromium kwintsimbi engagqwaliyo. Umxholo we-nickel wemibhobho yentsimbi engagqwaliyo ye-310S kunye ne-840 ufikelela kwi-20%, nto leyo eyimpahla egqwesileyo enokumelana ne-asidi enamandla kunye ne-alkali kunye nokumelana nobushushu obuphezulu kwimibhobho yokufudumeza.
Enyanisweni, intsimbi engagqwaliyo ye-301s ifanelekile ngakumbi kwi-oven yokufutha kunentsimbi engagqwaliyo ye-840, ukumelana nokugqwala kunamandla, kwaye akukho mfuneko yokukhathazeka malunga nokugqwala komphunga kunye nokugqwala kokugqobhoka ixesha elide emanzini, eyona mbhobho yokubhaka ifanelekileyo kwi-oven yokufutha.
Amanye amashishini asebenzisa intsimbi engagqwaliyo engama-840, aze asebenzise ibhanile ethi “umgangatho wezonyango” kunye “netyhubhu ye-oven yobungcali” ukukhohlisa abathengi. Enyanisweni, intsimbi engagqwaliyo engama-840 isetyenziselwa ii-oven zobungcali, kodwa i-oven ayilingani ne-oven yomphunga, ayinakutshintshwa ngasese, utshilo apha i-oven yomphunga enetyhubhu yokufudumeza yentsimbi engagqwali engama-840 kulula ukuyigqwala ngumphunga.
Indawo yeheater
Isikhundla seityhubhu yokufudumeza i-ovenyahlulwe ngokubanzi yaba yityhubhu yokufudumeza efihliweyo kunye netyhubhu yokufudumeza eveziweyo.
Ityhubhu yokufudumeza efihliweyo inokwenza umngxuma wangaphakathi we-oven ube mhle ngakumbi kwaye inciphise umngcipheko wokugqwala kwetyhubhu yokufudumeza. Nangona kunjalo, ngenxa yokuba ityhubhu yokufudumeza ifihliwe phantsi kwe-chassis yentsimbi engagqwaliyo, kwaye i-chassis yentsimbi engagqwaliyo ayinakumelana nobushushu obuphezulu kakhulu, nto leyo ebangela umda ophezulu wobushushu bokufudumeza ngqo ezantsi kwexesha lokubhaka phakathi kwama-150-160 degrees, ngoko ke kukho imeko yokuba ukutya akuphekwanga. Kwaye ukufudumeza kufuneka kwenziwe nge-chassis, i-chassis yentsimbi engagqwaliyo kufuneka ifudunyezwe kuqala, kwaye ukutya kufudunyezwe kwakhona, ukuze ixesha lingatyhileki.
Ityhubhu yokufudumeza eveziweyo kukuba ityhubhu yokufudumeza iveziwe ngqo ezantsi komngxuma ongaphakathi, nangona ibukeka ingathandeki. Nangona kunjalo, akukho mfuneko yokudlula kuyo nayiphi na indlela, ityhubhu yokufudumeza ifudumeza ukutya ngokuthe ngqo, kwaye ukusebenza kakuhle kokupheka kuphezulu. Usenokuba nexhala lokuba akulula ukucoca umngxuma ongaphakathi we-oven yomphunga, kodwa ityhubhu yokufudumeza inokusongwa kwaye inokucocwa ngokulula.
Emva kokwazisa okuninzi kangaka, ungaphindi uwele emngxunyeni ~ Xa uthenga i-oven yomphunga, kuya kufuneka uhlukanise umbhobho wobushushu, emva kwayo yonke loo nto, udlala indima ebalulekileyo kwisiphumo sokupheka se-oven yomphunga.
