Malangizo Oyika ndi Kusunga Mavavu Achipata Ampeni Osindikizidwa Ofewa

Zosindikizidwa zofewavalavu ya chipata cha mpenindi valavu yomwe imagwiritsa ntchito chisindikizo chopangidwa ndi zinthu zotanuka kuti ziwongolere kayendedwe ka madzi kudzera pachipata. Imadziwika ndi ntchito yabwino yosindikiza, torque yaying'ono yotsegula ndi kutseka, komanso moyo wautali wautumiki. Nkhaniyi ifotokoza za kusankha kwa zinthu, malingaliro okonza, masitepe oyika ndi kusamala kwa valve yotsekedwa ndi mpeni mwatsatanetsatane.

I. Kusankhidwa kwa zinthu za mavavu a zipata za mpeni zofewa

1.1 Zida za thupi la vavu

Kusankhidwa kwa zida zamtundu wa vavu kuyenera kuganizira malo ogwirira ntchito komanso mawonekedwe apakatikati a valve. Zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo chitsulo choponyedwa, chitsulo cha ductile, chitsulo cha carbon, chitsulo chosapanga dzimbiri, ndi zina zotero. Kwa media zowononga, ndi bwino kusankha zitsulo zosapanga dzimbiri kapena pulasitiki.

1.2 Zida zosindikizira

Zida zofewa zosindikizira nthawi zambiri zimaphatikizapo EPDM, NBR, PTFE, etc. EPDM ndi yoyenera madzi otentha, nthunzi ndi zofalitsa zina; NBR ndi yoyenera mafuta ndi hydrocarbon media; PTFE ili ndi kukana kwa dzimbiri komanso kutentha kwambiri.

1.3 Zida zamtundu wa valve

Zida za tsinde la valve ziyenera kukhala ndi mphamvu zabwino komanso kukana dzimbiri. Zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo zitsulo zosapanga dzimbiri ndi zitsulo za alloy. Kwa kutentha kwambiri komanso kuthamanga kwambiri, tikulimbikitsidwa kusankha zitsulo za alloy.

II. Malangizo osamalira mavavu a zipata za mpeni zomata zofewa

2.1 Kuyendera pafupipafupi

Yang'anani nthawi zonse ntchito yosindikiza ndi kutsegula ndi kutseka kwa ma valve, ndipo samalirani zovuta zilizonse panthawi yake. Samalani kwambiri poyang'ana kuvala kwa zisindikizo ndikuzisintha ngati kuli kofunikira.

2.2 Kuyeretsa ndi kuthira mafuta

Nthawi zonse muziyeretsa mkati ndi kunja kwa mavavu kuti mukhale aukhondo. Kwa ma valve omwe amatsegulidwa pafupipafupi komanso kutsekedwa, mafuta ayenera kuwonjezeredwa pafupipafupi kuti achepetse kugundana ndi kutha.

2.3 Chithandizo cha anti-corrosion

Kwa ma valve omwe amawonekera mumlengalenga, chithandizo cha anti-corrosion chiyenera kuchitidwa nthawi zonse kuti zisawononge thupi la valve ndi tsinde la valve. Njira zodziwika bwino zothana ndi dzimbiri zimaphatikizapo kugwiritsa ntchito utoto wotsutsa dzimbiri ndi electroplating.

III. Masitepe oyika ndi kusamala kwa mavavu a zipata zomata mpeni

3.1 Masitepe oyika

1). Yang'anani valavu: Musanakhazikitse, fufuzani ngati chitsanzo cha valve, ndondomeko ndi kupanikizika kwapakati zikukwaniritsa zofunikira za mapangidwe. Onetsetsani kuti malo osindikizira ma valve si owonongeka.

2). Tsukani mapaipi: Onetsetsani kuti palibe zitsulo zowotcherera, zosefera zachitsulo ndi zinyalala zina mupaipi kuti zisawonongeke zosindikizira.
3). Ikani valavu: ikani valavu mu payipi, konzani flange ndi mabawuti, ndipo tcherani khutu kumangitsa mabawuti diagonally kuteteza mphamvu yosagwirizana.
4). Sinthani valavu: mutatha kukhazikitsa, tsegulani ndi kutseka valavuyo pamanja kuti muwonetsetse kutseguka ndi kutseka popanda kugwedeza.

3.2 Kusamala

- Kuwongolera: Vavu yachipata cha mpeni wofewa imakhala ndi mayendedwe. Mukayika, samalani ndi momwe mayendedwe apakati amayendera mogwirizana ndi muvi pa thupi la valve.

- Pewani torque mopitilira muyeso: Mukatsegula ndi kutseka valavu, musagwiritse ntchito mphamvu zambiri kuti mupewe kuwonongeka kwa chisindikizo ndi tsinde la valve.

- Pewani kutentha kwakukulu: Pewani kuyika valavu pamalo otentha kwambiri kuti muteteze kukalamba ndi kuwonongeka kwa chisindikizo.

- Njira zoletsa kuzizira: M'malo ozizira, njira zoletsa kuzizira ziyenera kutengedwa kuti valavu isaundane.

Monga chida chofunikira chowongolera, kusankha zinthu, kukonza ndi kuyika chipata cha mpeni chosindikizidwa chofewavalavuzimakhudza mwachindunji ntchito ndi moyo wa valve. Kupyolera mu kusankha koyenera kwa zinthu, kukonza nthawi zonse ndi kuyika koyenera, kugwiritsa ntchito bwino komanso moyo wa valve yotsekedwa ndi mpeni wofewa ukhoza kusinthidwa bwino. Ndikukhulupirira kuti zomwe zili m'nkhaniyi zitha kupereka zothandiza kwa ogwiritsa ntchito.
