Nzeru Yogwiritsira Ntchito Zopangira Ma Vavu mu Zipangizo Zachitsulo: Kuchokera pa Mpando wa Vavu Kupita ku Lower Shaft

Mu makina akuluakulu owongolera mumakampani opanga zitsulo, magwiridwe antchito a ma valve a mpira ndi zida zolumikizira ma valve a chipata zimakhudza mwachindunji kukhazikika kwa ntchito ya mapaipi a uvuni ndi makina oziziritsira madzi. Nthawi zambiri, vuto lomwe limakhalapo silili ndi kapangidwe ka ma valve onse, koma ndi zigawo zazing'ono komanso zosaoneka bwino - monga kumira kwa mpando, kupotoka kwa shaft yotsika, kapena kutopa kwa bokosi lodzaza zinthu kukalamba. Ngati vutoli lamtunduwu likuchulukirachulukira, kuzungulira kwa bolodi sikuli pamalo ake, ndipo kupotoka kwa kutsegula ndi kutseka kudzakhala kulephera kwa dongosolo.

M'zaka zaposachedwa, tagwirizanitsa mapulojekiti a valavu ya mpweya wa oxygen main pipe ndi coke oven main line ball valve a main mills angapo achitsulo, ndipo mavuto omwe amapezeka nthawi zambiri amayang'ana kwambiri kapangidwe ka tsinde la valavu ndi moyo wa mpando wa kasupe. Zojambula zoyambirira za kasitomala zidagwiritsa ntchito mpando wa valavu wotsekedwa, koma mphamvu ya kasupe imalephera msanga pamene ikutsegulidwa ndi kutsekedwa pafupipafupi, ndipo pamwamba pake potseka ndi kovuta kuyika. Takonza kapangidwe kake, tasintha kukhala mpando wa kasupe wogawanika wokhala ndi malire a mbali ziwiri, ndipo kukana kwa shaft yapansi ndi mphete yothandizira kwakhala bwino kwambiri pambuyo pokonza nitriding.

Pa gawo monga shaft yotsika, zofunikira sizovuta, koma ziyenera kukhala zolunjika komanso zosagonjetseka. Ngati mpira ndi shaft sizikugwirizana, ngakhale magwiridwe antchito a actuator ali abwino, liwiro lotsegulira ndi kutseka lidzachepetsedwa ndi cholakwikacho. Tikagwirizana, timafunikira makasitomala kuti apereke kapangidwe ka mpira ndi shaft yapamwamba kuti azilamulira coaxiality.

Mu mtundu uwu wa pulojekiti yothandizira, 'zigawo zazing'ono' monga mabulaketi, maboneti, ndi mtedza wa tsinde nthawi zambiri zimakhala zinthu zofunika kwambiri zomwe zimatsimikiza moyo wa makina onse. Sakhudzidwa mwachindunji pakutseka, koma amatsimikiza ngati kutsegula ndi kutseka kuli kosalala. Anzanu omwe amachita malonda akunja mwina adakumana nawo: kasitomala akamayesa, sikofunikira kuyang'ana mawonekedwe, koma kusokoneza zojambula za msonkhano wosanjikiza ndi wosanjikiza kuti awone ngati kulondola kwa zigawo zazing'onozi kuli koyenera.

Chifukwa chake, ngakhale mutagwiritsa ntchito valavu, musaione ngati ndi yaying'ono, mavuto a kapangidwe ndi kukonza amatha kuwonekera panthawi yopangira pamalopo. Tikachita pulojekiti yamtunduwu, tidzalimbikitsa makasitomala kuti atumize zojambula kuti atsimikizire pulaniyo, ndi kutsimikizira ndi kuyikapo musanayike batchi, makamaka pazida zomwe zimalumikizana monga mipando ya valavu, mipando ya masika, ndi ma tsinde a valavu.
