Indlela yokubala izinga lokunyibilika kunye nemveliso yesithando sokunyibilikisa i-induction?

Kufuneka kucaciswe ukuba idatha yokunyibilika kwedatha yesithando sombane esinikezelwe nguwonke wonke ukuchithwa kwesithando somlilo umenzi kwisampulu okanye iinkcukacha zobuchwephesha lizinga lokunyibilika. Izinga lokunyibilika kwesithando sombane luphawu lwesithando sombane ngokwaso, sinxulumene namandla esithandweni sombane kunye nohlobo lomthombo wamandla, kwaye alunanto yakwenza nenkqubo yokusebenza yokuvelisa. Imveliso yesithando sombane ayihambelani kuphela nokusebenza kwezinga lokunyibilika kwesithando sombane ngokwaso, kodwa sinxulumene nenkqubo yokusebenza yokunyibilika. Ngokuqhelekileyo, kukho ixesha elithile elincedisayo elingenamthwalo kumjikelo wokunyibilika komsebenzi, okufana noku: ukutyisa, ukucofa, ukucofa, ukucofa iisampulu kunye nokuvavanya, ukulinda iziphumo zovavanyo (ezinxulumene neendlela zokuvavanya), ukulinda ukugalelwa, njl. njl. la maxesha ancedisayo angenamthwalo anciphisa igalelo lamandla ombane, oko kukuthi, ukunciphisa umthamo wokunyibilika kweziko lombane.

Ukucacisa inkcazo, sazisa iikhonsepthi zosetyenziso lwamandla eziko lombane i-K1 kunye nosetyenziso lwamandla okusebenza umba we-K2.

Usetyenziso lwamandla eziko lombane lwe-K1 lubhekiselele kumlinganiselo wamandla aphumayo obonelelo lwamandla kumandla alinganisiweyo ngexesha lokunyibilika kwawo wonke umjikelo wokunyibilika, kwaye inxulumene nohlobo lonikezelo lwamandla. Ixabiso le-K1 le-intermediate frequency induction furnace lixhotyiswe ngesilicon elawulwayo (SCR) full-bridge parallel inverter unikezelo lwamandla oluqinileyo luhlala lujikeleze i-0.8. I-Xi’an Institute of Mechanical and Electrical Technology yongeze ulawulo lwe-inverter kulolu hlobo lonikezelo lwamandla (ngokuqhelekileyo olu hlobo lombane lunolawulo lokulungisa kuphela), ixabiso lingasondela kwi-0.9 okanye kunjalo. Ixabiso le-K1 le-intermediate frequency induction furnace lixhotyiswe nge (IGBT) okanye (SCR) isiqingatha sebhulorho yochungechunge lwe-inverter yokwabelana ngombane oqinileyo unokufikelela kwithiyori kwi-1.0.

Ubungakanani bokusetyenziswa kwamandla okusebenza komlinganiso we-K2 unxulumene nezinto ezifana noyilo lwenkqubo kunye nenqanaba lolawulo lweworkshop yokunyibilika, kunye neskimu soqwalaselo lonikezelo lwamandla eziko lombane. Ixabiso layo lilingana nomlinganiselo weyona mveliso yamandla ombane kumandla okuphuma okulinganiselweyo ngexesha lomjikelezo wonke wokusebenza. Ngokubanzi, i-coefficient yokusetyenziswa kwamandla i-K2 ikhethwa phakathi kwe-0.7 kunye ne-0.85. Ifutshane ixesha elincedisayo lokungabikho komthwalo kwiziko lombane (elifana: ukutyisa, isampuli, ukulinda ukuvavanywa, ukulinda ukugalelwa, njl.), ixabiso le-K2 likhulu. Ukusebenzisa iTable 4 Scheme 4 (unikezelo lwamandla amabini kunye nenkqubo yesithando somlilo), ixabiso le-K2 linokuthi lifikelele kwi-1.0, enyanisweni, linokufikelela ngaphezu kwe-0.9 xa ixesha lokusebenza elincedisayo elingenamthwalo wesithando sombane liphantsi kakhulu.

Ke ngoko, imveliso ye-N yesithando sombane ingabalwa ngolu hlobo lulandelayo:

N = P·K1·K2 / p (t/h)………………………………………………………………(1)

phi:

P — amandla alinganisiweyo eziko lombane (kW)

I-K1-Into yokusetyenziswa kwamandla eziko lombane, idla ngokuba kuluhlu lwe-0.8 ~ 0.95

K2 — Ukusetyenziswa kwamandla okusebenza, 0.7 ~ 0.85

p — Ukusetyenziswa kweyunithi yokunyibilika kwesithando sombane (kWh/t)

Thatha i-10t intermediate intermediate intermediate induction melting furnace ene-2500kW silicone controlled (SCR) full-bridge parallel inverter umbane oqinileyo oveliswe liZiko lobuNjineli booMatshini kunye noMbane njengomzekelo. Iyunithi yokusetyenziswa kokunyibilika kweyunithi p ebonakaliswe kwiinkcukacha zobugcisa yi-520 kWh/t, kunye ne-firnace power utilization factor Ixabiso le-K1 linokufikelela kwi-0.9, kwaye ixabiso lokusetyenziswa kwamandla okusebenza kwi-K2 lithathwa njenge-0.85. Imveliso yesithando sombane inokufumaneka ngolu hlobo:

N = P · K1 · K2 / p = 2500 · 0.9 · 0.85 / 520 = 3.68 (t/h)

Kufuneka kuphawulwe ukuba abanye abasebenzisi bayabhidanisa intsingiselo yesantya sokunyibilika kunye nemveliso, kwaye bazithathe njengentsingiselo efanayo. Abakhange bathathele ingqalelo i-coefficient yokusetyenziswa kwamandla eziko lombane i-K1 kunye ne-coefficient yokusetyenziswa kwamandla okusebenza i-K2. Isiphumo solu balo siya kuba N = 2500/520 = 4.8 (t / h). Isithando sombane esikhethiweyo ngale ndlela asikwazi ukufezekisa imveliso eyiliweyo.
