1.6temporam yotsimikizira kuti mayesedwe imayenera kutsimikiziridwa komanso yodalirika pambuyo poyang'ana.
1.7check kaya mavavu onse pa mapaipi ndi otseguka, ngati mapepalawo adawonjezeredwa, ndikuyimitsa Valavu ya valavu ya valavu, kenako khazikitsani mpaka litaimbidwa.
2.pricess Paipeline oyeserera
2.1. Kupanikizika kwamapaipi ndi 1.5 nthawi yokakamiza.
2.2. Pamene mapaipi ndi zida amayesedwa ngati dongosolo, kusokonekera kwa mapaipi ndilofanana kapena kuchepera kuposa kuponderezana kwa chipangizocho. Chabwino
2.3. Mukamakamwa madzi, mpweya uyenera kutopa. Mphepo yamtunduwu ikuyenera kukhala pamalo okwera pa mapaipi ndikuwonjezera valavu yotulutsa.
2.4. Mapaipi okhala ndi maudindo akulu ayenera kuyesedwa kukakamizidwa mayeso a mayeso. Kupsinjika kwa masitepe amadzimadzi kuyenera kukhala okakamizidwa kwambiri, koma malo otsika kwambiri sayenera kupitirira kulekerera mapaipi.
2.5. Mukapanikizika, kulimbikitsa kuyenera kuchitidwa pang'onopang'ono. Kupanikizika koyesedwa, kukakamizidwa kumayenera kukhala mphindi 10. Popanda kutaya, palibe kusokoneza koyenera, kuthamanga kwa mayeso kumachepetsedwa kukapanikizika. Chabwino
2.6. Kuyesedwa kwatha, mbale yakhungu iyenera kuchotsedwa munthawi yamadzi. Panthawi ya ngalande, kukakamizidwa kuyenera kulephera, ndipo palibe zotulukapo zomwe zingathetsedwe kulikonse. Ngati kutayikira kumapezeka mukamayesedwa, sikuloledwa kuthandizidwa. Atatha kuthetsa vutoli, mayesowo amayenera kukhazikitsidwanso.
2.7. Kuyesedwa kwa kutayikira kunachitika pambuyo poyesa kukanikiza kunali koyenera, ndipo sing'angayo adakakamizidwa ndi mpweya.
2.8. Kukakamizidwa kwa mayeso osinthira ndi kukakamizidwa kwa kapangidwe. Kuyesedwa kwa kutaya kuyenera kuyang'ana kwambiri poitchera. Chingwe kapena ulusi wolumikizidwa ndi valavu yopanda kanthu, valavu yotulutsa, ndi valavu yowunikira.

3.1. Zofunikira zaukadaulo
3.1.1 Njira yomwe ilipo iyenera kuwombedwa ndikutsukidwa m'magawo (otchedwa kuphulika).
3.1.2 Njira yowuzira imatsimikiziridwa molingana ndi zofunikira za mapaipi, sing'anga wogwira ntchito, ndi dothi pamwamba pa mapaipi. Kuphulika kwa kuwomba kumachitika nthawi zambiri kuti apange woyang'anira, thandizo, ndi mapaipi otayira.
3.1.3 Tisanawomberedwe, chida chomwe chidakhazikitsidwa, ndipo bolodi ya Core, Fyuluta Refving Valve ndi kuyimitsa valavu pachimake champhamvu iyenera kugwetsedwa, ndipo akusungidwa bwino.
3.1.4 Pakuwomba, ma ducto sayenera kulowa chipangizocho, ndipo ziwalo zowombedwa kuchokera ku zida siziyenera kulowa pa mapaipi.
3.1.5 Zipangizo ndi mapaipi omwe saloledwa kutsukidwa ziyenera kukhala zazitali kuchokera pakuwomba.
3.1.6 Kuwombera mapaipi kuyenera kukhala kokwanira. Kupsinjika kwa kuwomba kwa kuwomba sikuyenera kupitirira zokakamiza. Kuchuluka kwake kumakhala kochepera 20m / s. Mukawomba, gwiritsani ntchito nyundo yamatabwa kuti mugogoda chubu. Osawononga chubu.
3.1.7 Ganizirani kulimba kwa nthambi yamapaipi ndi chingwe chopachika chisanachoke, ndikulimbikitsidwa ziyenera kuperekedwa ngati pakufunika.
3.2. Kuwombera mapaipi, kuyeretsa njira
3.2.1 Madzi akutuluka: Sing'anga wogwira ntchito ndi mapaipi a madzi. Mphepete imatha kufika poyambira kapena osachepera 1.5m / s mu chitoliro. Mtundu wamadzi wotumizira ndi kuwonekerako ndizogwirizana ndi kuyendera kowoneka pakhomo. Pambuyo pa mapaipiwo ndi woyenerera, madziwo ayenera kutopa nthawi.
3.2.2 Kuwombera kwa mpweya: Sing'anga wogwira ntchito ndi mapaipi a gasi. Aliyense amene amakumana ndi valavu ayenera kuwononga chivundikiro cham'mbuyomu ndikuwonjezera chosokoneza, kenako ndikukonzanso pambuyo pa bomba. Kupanikizika sikuyenera kupitirira kukakamiza kwa chidebe ndi mapaipi, ndipo kuchuluka kwake sikuyenera kukhala kochepera 20m / s. Panthawi yophulika, mukamasuta utsi ndi fumbi, kuyendera matabwa oyera kumayikidwa pa doko loyera, ndipo palibe dzimbiri, fumbi, chinyezi komanso zinyalala zina zoyambira mphindi 5.
3.2.3 Kuwomba Steam: Sing'anga yogwiritsira ntchito imasambitsidwa ndi mapaipi a Steam ya mapaipi otentha. Steate imawomba, chubu yofunda iyenera kukwezedwa pang'onopang'ono kuti iphulitse, kenako imazizira kutentha kwachilengedwe. Pakamwa pa malo othamangitsidwa ndi nthunzi zimakhazikika m'mwamba, ndipo logo ili ndi maso. Mawonekedwe a chitoliro chopopera sayenera kukhala laling'ono kuposa mainchesi a bomba lowomba. Miyezo yeniyeni: Sinthani bolodi yandamale kawiri motsatana. Panthawi zonse ziyeneretso zonse), ndikuwunika koyesa.
3.2.4 Kukonzanso mapaipi: Kuyesedwa kwapaipi ndi koyenera, bolodi yakhungu iyenera kuchotsedwa munthawi yake malinga ndi zolembedwa, ndi valavu yovomerezeka, yoyimitsa valavu yolowera, chida.
