Kusindikiza pamwamba

Nkhope Yokwezeka, (Yamkazi) Yoyang'anizana ndi mphete

Flange wakhungundi mtundu wa flange wopanda bowo pakati, womwe nthawi zambiri umagwiritsidwa ntchito kusindikiza potseka mapaipi.

Wakhungu wa zilembo 8 amatchulidwa dzina lake lofanana ndi zilembo 8, ndipo dzina lake lachingerezi ndiZowona zakhungu. Ndi mbale yachitsulo yokhala ndi makulidwe okhazikika omwe amagawidwa m'ma diski awiri.

Ma discs awiri a mawonekedwe akhungu akhungu amalumikizidwa ndi chitsulo chathyathyathya, chimodzi mwazomwe ndi chimbale cholimba ndipo chinacho ndi mphete yozungulira, yokhala ndi m'mimba mwake yamkati yogwirizana ndiflange.

Flange yakhungu yooneka ngati 8 ndi mtundu wa chigawo cha mapaipi omwe angagwiritsidwe ntchito kudzipatula kapena kulumikiza kachitidwe ka mapaipi. Makamaka pofuna kukonza bwino, nthawi zambiri amagwiritsidwa ntchito popanga mapaipi omwe amafunikira kusintha kwa njira.

Kapangidwe

Pamene pali ma valve awiri otsekera kutsogolo ndi kumbuyo kwa flange yakhungu yooneka ngati 8, ndipo onse ali otsekedwa, sinthani mawonekedwe akhungu. Njira zodziwika bwino zimaphatikizapo kugwiritsa ntchito ndikusunga zosinthira kutentha, kugwiritsa ntchito ndi kusunga ma reactors, ndi kulumikizana pakati pa mapaipi a nayitrogeni ndi mapaipi opangira.

Mawonekedwe akhungu owoneka bwino nthawi zambiri amafunikira kulekanitsidwa ndi zida zina kapena zida zamapaipi. Nthawi zambiri, mbale yakhungu yooneka ngati 8 imakhala pamalo otseguka kuti madzi azitha kudutsa mupaipi. Pamene mbale yakhungu yooneka ngati 8 ili pamalo otsekedwa, payipi imatsekedwa ndipo madzimadzi amatsekedwa.

Kukonzekera kwa mapaipi ndi chimodzi mwazifukwa zomwe mbale yakhungu yooneka ngati 8 imazungulira pamalo otsekedwa. Pali bowo lobowola m'mimba mwa mbale 8 yolumikizira mbale zakhungu. Masulani ndi kugawa mabawuti ena, ndipo mbale yakhungu yooneka ngati 8 imatha kuzungulira pakati pa ma flanges. Pambuyo posintha gasket, ma bolts amatha kulumikizidwanso ndikumangika.

Khalidwe

Zodziwika bwino komanso zosavuta kuzindikira mawonekedwe ake. Ntchito yayikulu ya mbale yayikulu eyiti yokhala ndi mawonekedwe akhungu ndikuyilekanitsa kwathunthu. Zovala zakhungu zimagwiranso ntchito mofananamo kudzipatula ndi kudula monga mitu, zipewa za mapaipi, ndi zomangira zowotcherera. Chifukwa cha ntchito yake yabwino yosindikiza, nthawi zambiri imagwiritsidwa ntchito ngati njira yodalirika yodzipatula pamakina omwe amafunikira kudzipatula kwathunthu.
Zovala zakhungu ziyenera kuikidwa m'malo omwe amafunikira kudzipatula (kudula), monga pa doko lolumikizira zida, isanayambe kapena itatha valavu yotseka, kapena pakati pa ma flanges awiri. Nthawi zambiri amalimbikitsidwa kugwiritsa ntchito mbale yakhungu yooneka ngati 8; Ikani mbale (zozungulira zozungulira zakhungu) zitha kugwiritsidwanso ntchito nthawi imodzi monga kukanikiza ndi kuwomba.

Tanthauzo la ntchito

Nthawi zambiri amagwiritsidwa ntchito pamapaipi okhala ndi mainchesi okulirapo, mbali imodzi ya flange imagwiritsidwa ntchito kutengera malo ndikusunga mapaipi osatsekeka. Ngati ndi kotheka, mapeto ena amasinthidwa ndi mbale yakhungu ya makulidwe omwewo kuti adule payipi. Kupewa anakakamizika kukula kwa mapaipi chifukwa chosakhalitsa m'malo akhungu mbale, zimene zingakhudze dongosolo lonse.
