Ukuhamba kwenkqubo yokucima umbhobho wentsimbi kunye nomgca wokuvelisa ubushushu

Kuyafana neziko lokufudumeza igesi eliqhelekileyo eliqhelekileyo, kodwa umgaqo wokusebenza kunye nobunjineli bokucubungula zahluke ngokupheleleyo. Kwisithando somlilo esihamba ngegesi, umbhobho wensimbi ufudumala ngokupheleleyo; ngelixa kwi ukufudumeza iziko, umbhobho wensimbi uqhubeka ukufudumala inyathelo ngesinyathelo; inkqubo yokucima kunye nenkqubo yokufudumala nayo iqhutywe ngendlela efanayo. Ngoko ke, xa umbhobho wentsimbi ufudunyezwa, ucinywe, kwaye unomsindo, ngokusisiseko uhamba ngokude kunye ne-spiral, kwaye enye ishukunyiswa ecaleni. Inkqubo ethile yokucubungula imi ngolu hlobo lulandelayo: Ngokweemfuno zokucinywa kunye nobushushu bomgangatho we-API 5 CT yemibhobho yomthombo we-oyile, izikhewu zemibhobho ye-oyile zinyuswa ukusuka kwi-crane ephezulu ukuya kwiqonga lokulayisha, kwaye emva kokuhlolwa kwenkangeleko ngesandla, ziyaphakanyiswa. zicwangciswe kakuhle kwaye zasasazwa. Xa indawo nganye yomsebenzi womgca wemveliso ingena kwimeko yokusebenza eqhelekileyo, i-sensor inamandla okulinda izinto, i-frequency feeder eguquguqukayo iqala ukujikeleza, kwaye i-steping feeder iqhutywa ngesandla ukuphakamisa ngokutyibilikayo umbhobho we-oyile wokuqala ukusuka kwindawo yokuphuma. ekupheleni kweqonga lokutya. Ithunyelwa kwitheyibhile ye-roller yesixhobo sokulungelelanisa, kunye ne-frequency conversion feeder feeder phambili ngesantya esimiselweyo. I-frequency conversion feeder yi-single-roller drive enesantya esilungelelanisiweyo kunye nobude. Uhlobo lwe-roller luyi-feeder eyenzelwe ngokukodwa i-roller ene-inclined 15 ° ilungiselelo. Ukutya okuthe tyaba okuziko ulungiso kunye nomsebenzi wokuzijikeleza. I-roller yokutya phakathi kwee-coil zokufudumeza zokufudumeza kunye ne-roller yokutya kwindawo yokungena kunye ne-outlet yenziwe ngentsimbi ekwazi ukumelana nobushushu, kwaye ixhotyiswe ngesixhobo sokupholisa sangaphakathi esijikelezayo esitywiniweyo sokupholisa i-roller yokutya kunye nokwenza umphezulu wangaphandle we-roller yokutya Ukomisa. iququzelela ukufudumeza okuqhubekayo kwe-tubing, kwaye intsalela ye-roller feed yenziwe ngentsimbi engagungqiyo. Umbhobho we-oyile ungena kwindawo ephakathi yokucima ukucima ukufudumeza ngetafile yerola. Indawo yokufudumeza yenziwe ngeseti ye-3000kW yonikezelo lwamandla ombane ophakathi kunye neseti ye-1200kW yonikezelo lwamandla ombane ophakathi kunye neeseti ezininzi zeekhoyili zokufudumeza zokufudumeza ukwenza indawo yokufudumeza yokucima ukuze kuqinisekiswe ubushushu obufanayo bomsebenzi. Ubushushu bobushushu yi-850℃～1000℃. Faka i-thermometer ye-infrared enemibala emibini ephuma kumazwe angaphandle kwi-coil yokufudumeza ukujonga ubushushu bobushushu be-tubhing, kunye nengxelo yomqondiso kwinkqubo yolawulo lonikezelo lwamandla ombane ophakathi ukuhlengahlengisa ngokuzenzekelayo amandla emveliso yamandla aphakathi aphakathi. ukubonelela ukwenza inkqubo yokulawula i-loop evaliweyo ukulungelelanisa Ukushisa kokushisa kombhobho wensimbi kulawulwa ngaphakathi kwinqanaba elivumelekileyo lephutha.

Umbhobho wensimbi ovuthayo ungena kwindawo yokucima isitshizi. Ekubeni i-workpiece yenziwe ngentsimbi ye-carbon-manganese enomxholo wekhabhoni malunga ne-0.3% okanye i-alloyed chromium-molybdenum iron kunye nentsimbi ye-chromium-manganese-molybdenum, amanzi ahlambulukileyo afanelekile kwi-medium quenching. Sisebenzisa isixhobo sokupholisa esine-ring-shaped ukuze siqhubeke sitshiza amanzi aphakamileyo aphezulu phezu kombhobho wensimbi evuthayo, kwaye sitshize ngamandla malunga nemizuzwana emi-5-15 ukufezekisa ukuguqulwa kwe-martensite ecinyiweyo. Ngenxa yesi sizathu, sikhethe iiseti ezimbini zeempompo zamanzi eziphezulu kunye noxinzelelo oluphezulu (uxinzelelo lweemitha ezili-125 ngomzuzu kunye nokujikeleza kwamanzi yi-1000m3 / h), kwaye amandla ewonke angaphezulu kwe-500kW, ukuze kufezekiswe isiphumo sokupholisa ngokukhawuleza kunye okufanayo okufunekayo ukucima ngokupheleleyo udonga lombhobho. Qinisekisa ukuba ifilimu ye-steam eyenziwe phezu kombhobho wentsimbi iyatshatyalaliswa, ukwenzela ukuba umbhobho wensimbi ufikelele ngokukhawuleza kwiqondo lokushisa lokuguqulwa kwe-martensite, kwaye yonke into iya kuguqulwa ibe yi-martensite ecinyiweyo, kwaye akukho troostite ecinyiweyo iya kuveliswa, ngaloo ndlela iqinisekisa. i-sorbite enomsindo. Ekubeni isikali se-oksidi kunye nothuli kumphezulu wombhobho wentsimbi uya kuwa kwisitshizi kwaye ungene kwindawo yokucima, indawo yokucima kufuneka icutshungulwe ngokuhluzwa okurhabaxa kwetanki yentlenga, ukuhluzwa kwemagnethi, ukuhluzwa komnatha kunye nokunye okuninzi. unyango lweqonga ukwenza amanzi amdaka acoceke kwaye angavaleki. Umbhobho unokuphinda usetyenziswe.

Indawo yokutshiza ixhotyiswe ngee-baffles zodwa ukuthintela ukuchaphaza kwamanzi, okuluncedo ekuhlaziyweni kwamanzi kunye nokunciphisa ilahleko yamanzi amdaka. Isigqubuthelo esikhuselayo sikwamiselwe ukuthintela ukutshizwa komphunga ukuqinisekisa ukoma kweworkshop.

Umbhobho wensimbi otshisiweyo uthuthwa ukusuka kwitafile ye-roller ukuya kwicandelo lokususa amanzi kumbhobho, kwaye umbhobho uphakanyiswe kwitafile ethambekele ngomatshini wokuguqula umoya. Emva kokukhupha amanzi ngaphezu kwemizuzu emi-5, iphakanyiswe ngumatshini wokujika we-pneumatic ukuya kwitafile ye-teering line roller. Ngaphantsi komqhubi wetafile eqengqelekayo, ingena kwindawo yokufudumeza yobushushu obuphakathi, kunye noluhlu lobushushu bobushushu buqhele ukuba yi-600°C ukuya kuma-750°C. Unikezelo lwamandla okufudumeza okuphakathi olwenziwa ngamaza aphakathi yindawo yokufudumeza yokufudumeza eyenziwe iseti ye-1900kW kunye neseti ye-900kW ebandakanya amaqela amaninzi eekhoyili zokuqhelanisa. Ithemometha ye-infrared enemibala emibini ephuma kumazwe angaphandle ifakwe ekuphumeni kwekhoyili yokugqibela yokubeka iliso kubushushu bombhobho weoyile, kwaye inoxanduva lokutyisa umva umqondiso kunikezelo lwamandla ombane ophakathi kunye nokulungelelanisa ngokuzenzekelayo amandla aphumayo aphakathi. unikezelo lwamandla ombane ukwenza inkqubo yolawulo evaliweyo. Umbhobho wensimbi ovuthayo udlula kwisixhobo sokunciphisa amanzi soxinzelelo oluphezulu kwitafile ye-roller. Umbhobho wensimbi ufezekisa umphumo wokuhla phantsi kokuhlanjululwa kwamanzi e-jet high-pressure. Umbhobho wensimbi emva kokuhla udlula kwi-sensor kwindawo yokufudumala kwaye uguqulelwe ngesinyathelo sokuqhuba i-pneumatic ngesinyathelo. I-feeder iphakamisa umbhobho wentsimbi ngokuthe ngcembe, iwubeke phezu kwebhedi yokupholisa kwaye ijikeleze ngokucothayo kwaye iqengqeleke, iphole ngokuthe ngcembe. Emva koko iibhobho zetsimbi ziqokelelwa kwiibhasikithi ekuphumeni kwebhedi yokupholisa, kwaye emva koko ziboshwe ngesandla, zipakishwe kwaye ziphakanyiswe kwicandelo elilandelayo.
