Momwe mungawonetsere chitetezo chogwiritsa ntchito machubu opopera othamanga kwambiri
Machubu a boiler amagwiritsidwa ntchito m'malo ovuta kwambiri.Amagwiritsidwa ntchito kwambiri m'mapaipi achilengedwe ndi mafuta ndi gasi.Zomwe zimagwiritsidwa ntchito nthawi zambiri ndi:15CrMo Alloy Steel Tube,16Mo3 Aloyi Chitoliro Chopanda Zitsulo,12Cr1MoV Aloyi Yopanda Zitsulo Chubu,20G Aloyi Yopanda Boiler Pipe.Ndi kuyang'anira kotani komwe kumayenera kuchitidwa musanagwiritse ntchito chubu chowotchera kuti muwonetsetse kuti chikugwiritsidwa ntchito bwino?
1. Samalani mwapadera pamene mukugwirizanitsamachubu othamanga kwambiri.Musakhale omangika kwambiri kuti mupewe kuwononga mapindikidwe olumikizana ndi kuwonongeka kwa kapangidwe kake, kupangitsa kutayikira ndikupangitsa kuti zisagwiritsidwe ntchito.
2. Izi ndizofunikira pakuyesa koyesa koyamba (mwachitsanzo, kuyang'ana kuthamanga kwa chubu) (a).Kuthamanga kwa chubu chofiira ndi 15000 0psi.
(b) Kuthamanga kukakwera kufika ku (a) 15000 0pSi kapena (b) 800 0pSi, kuthamanga kwa chubu chakuda ndi 800 0pSi, kupanikizika kumayimitsidwa kwa mphindi 2 mpaka 5 mphindi, ndiyeno kufufuzidwa ngati mawonekedwe aliwonse. , monga mimba yaikulu, kutayikira., chubu, ngati sizichitika, zonsezi ndi zachilendo, ndipo ngati E ndizochitika zachilendo, chubu chowotcha sichingagwiritsidwe ntchito, chiyenera kuletsedwa mwamphamvu.Iyenera kubwezeredwa kwa wogulitsa kapena kampani yogulitsa.
atatu.Musanagwiritse ntchito, yang'anani mawonekedwe aliwonse, monga mawonekedwe a deformation, chophatikiziracho chikanikizidwa, ndipo kasupe wamutu wapawiri (manja a rabara) ayenera kuikidwa pambali.(Mkono wa kasupe (mkono wa rabara) ndi gawo losalimba kwambiri la olowa ndi chubu la boiler).Ikhoza kupeŵa kutayika kwa madigiri 90 kapena 180 pamene ikusonkhanitsa chitoliro, ndipo imakhala yosavuta kuphulika kapena kutayikira ikagwiritsidwa ntchito.Zikuchitika.
Kusamalira ndi kusungirako machubu opopera othamanga kwambiri
1. Kukonzekera kwa chubu chapamwamba chopopera ndi chophweka kwambiri, malinga ngati kumatsukidwa mu mawonekedwe ozungulira ndi ozungulira ndi mankhwala oyeretsera (methanol) mu chubu mpaka kutsukidwa, kenako kutsukidwa ndi woyeretsa woyera; makamaka kusiya chotsukira mu chubu.
2. Ponyamula machubu otenthetsera, palibe kuchotsera kapena digiri ya 90 kapena kusonkhanitsa zolendewera, chifukwa kupindika kapena kusonkhanitsa madigiri 90 kudzawononga kapangidwe kake ndipo nthawi yopumira idzakhala madigiri 90, ndiye tikulimbikitsidwa kugwiritsa ntchito zosungirako zozungulira kuti ziletse kuyimitsidwa.
