Momwe mungathetsere mavuto omwe adachitika pokonza flange yachitsulo chosapanga dzimbiri?

Zitsulo zosapanga dzimbiri zimagwiritsidwa ntchito kwambiri m'mbali zonse za moyo chifukwa cha maonekedwe awo okongola, kutentha kwakukulu ndi kukana kuthamanga kwapamwamba, kukana kwa dzimbiri ndi makhalidwe ena. Komabe, anthu ambiri akadali ndi mavuto ambiri pokonza flanges zitsulo zosapanga dzimbiri. Lero tikambirana za momwe tingathetsere mavuto omwe amachitika pakapanda kukonza ma flanges achitsulo chosapanga dzimbiri.

Kukonzekera kwachitsulo chosapanga dzimbiri flangeayenera kudziwa ndi kulabadira mavuto ena:

1. Weld joint chilema: kuwotcherera kuwotcherera flange zitsulo zosapanga dzimbiri ndi lalikulu kwambiri. Ngati kupukuta kwamakina kumagwiritsidwa ntchito popangira izo, zizindikiro zopera zidzayambitsa kusagwirizana pamwamba ndikukhudza maonekedwe;

2. Osagwirizana kupukuta ndi passivation: pambuyo kupukuta Buku ndi kupukuta, n'zovuta kukwaniritsa yunifolomu ndi yunifolomu mankhwala zotsatira workpieces ndi dera lalikulu, ndipo sangathe kupeza abwino yunifolomu pamwamba. Kulumikizana kwa khosi la flange kapena kulumikiza kwa flange kumatanthawuza kulumikizana komwe kungatheke kwa flange, gasket ndi bawuti ngati gulu lophatikizana losindikiza.

Chitoliro cha chitoliro chimatanthawuza ku flange komwe kumagwiritsidwa ntchito popanga mapaipi mu chipangizo cha payipi, ndi zolowera ndi zotuluka za zida zikagwiritsidwa ntchito pazida. Pali mabowo paflange, ndipo mabawuti amapangitsa kuti ma flange awiriwo agwirizane kwambiri. Matako-kuwotcherera flange ndi mtundu wa zovekera chitoliro, kutanthauza flange ndi khosi ndi kuzungulira chitoliro kusintha ndi ogwirizana ndi chitoliro matako kuwotcherera. Sikophweka kupunduka, kusindikizidwa bwino komanso kugwiritsidwa ntchito kwambiri. Ndi oyenera mapaipi ndi kusinthasintha lalikulu kuthamanga kapena kutentha kapena mapaipi ndi kutentha, kuthamanga ndi kutentha otsika. Ubwino wake ndikuti mtengowo ndi wotsika mtengo, ndipo kukakamiza mwadzina sikudutsa 2.5MPa;

Amagwiritsidwanso ntchito m'mapaipi onyamula zotsika mtengo, zoyaka komanso zophulika, zokhala ndi mphamvu yazambiri ya PN16MPa. Palinso kuipa kwake, monga mtengo wa maola ogwira ntchito ndi zipangizo zothandizira;

3. N'zovuta kuchotsa: pickling ndi passivation, kuwonongeka kwa mankhwala kapena electrochemical corrosion ndipo dzimbiri lidzachitika pamaso pa zowononga zowonongeka (zosankha), ndi carbon steel, spatter ndi zonyansa zina zomwe zimamatira pamwamba pa chitsulo chosapanga dzimbiri. chifukwa cha zokopa ndi kuwotcherera spatter sangathe kuchotsedwa;

Ndiye momwe mungathetsere vuto lachitsulo chosapanga dzimbiri flangeprocessing?

1. Sankhani osatchula kanthu, ndiyeno lowetsani ndondomeko yotsatira. Osiyana workpieces mu zosapanga dzimbiri flange processing kulowa ndondomeko lolingana ndi zofunika processing;

2. Popinda, chida ndi poyambira zomwe zimagwiritsidwa ntchito popinda ziyenera kutsimikiziridwa molingana ndi kukula kwa zojambulazo ndi makulidwe a chitsulo chosapanga dzimbiri 304 chitoliro chopanda chitsulo. Chinsinsi cha kusankha nkhungu yapamwamba ndikupewa kusinthika komwe kumachitika chifukwa cha kugundana pakati pa flange ndi chida (kulongosola: gawo lofunika la fanizo) (zitsanzo zosiyana za nkhungu zapamwamba zingagwiritsidwe ntchito pa chinthu chomwecho). Kusankhidwa kwa nkhungu yapansi kumatsimikiziridwa molingana ndi makulidwe a mbale. Mukalumikiza pampu ndi valavu ya wopanga flange ndi payipi, zigawo za zidazi zimapangidwiranso mawonekedwe ofanana, omwe amadziwikanso kuti kulumikizana kwa flange.

3. Pofuna kuwotcherera mwamphamvu, nkhonya pamphuno pa workpiece kuti welded, amene angathe kupanga kugunda kukhudzana ndi mbale lathyathyathya wogawana pamaso mphamvu pa kuwotcherera kuonetsetsa kugwirizana Kutentha pa mfundo iliyonse, komanso kudziwa malo kuwotcherera. , yomwe imafunika kuwotcherera. Sinthani nthawi yosindikizira, nthawi yokakamiza, nthawi yokonza, ndi nthawi yopuma kuti muwonetsetse kuti chogwiriracho chikhoza kulumikizidwa mwamphamvu.
