Momwe mungayikitsire valve yosindikiza Gasket

Gaskets ndi gawo lodziwika kwambiri la zida.

Factory gasket, kodi mwayiyika bwino?

Ngati atayikidwa molakwika, gasket ikhoza kuonongeka panthawi yogwiritsira ntchito zida ndipo ingakhale yoopsa.

Ndi zida zotani zomwe zimafunikira pakuyika?

Konzani zida zotsatirazi musanaziike:

Wrench ya torque yolinganizidwa, wrench yomangira ma hydraulic, kapena zida zina zomangira;

Chitsulo waya burashi, mkuwa burashi ndi bwino;

Chisoti

Magalasi

Mafuta

Zida zina zodziwika ndi fakitale, ndi zina

Kuyeretsa ndi kumangiriza zomangira kumafuna zida zosiyanasiyana, kuwonjezera apo, zida zoikirapo zokhazikika ndi machitidwe otetezeka ziyenera kutsatiridwa.

Masitepe oyika

1. Yang'anani ndi kuyeretsa:

Chotsani zinthu zakunja ndi zinyalala pamalo osindikizira a gasket, zomangira zosiyanasiyana (maboliti, zipilala), mtedza ndi ma gaskets;

Yang'anani zomangira, mtedza ndi ma gaskets ngati ma burrs, ming'alu ndi zolakwika zina;

Yang'anani ngati mawonekedwe a flange ndi opindika, ngati pali zokopa za radial, ngati pali zida zakuya, kapena zolakwika zina zomwe zimakhudza malo olondola a gasket;

Ngati choyambitsa cholakwika chikapezeka, chiyenera kusinthidwa munthawi yake.Ngati muli ndi kukayikira ngati mungasinthe, mutha kulumikizana ndi wopanga zisindikizo munthawi yake.

2. Gwirizanitsani flange:

Gwirizanitsani nkhope ya flange ndi bowo la bawuti;

Mkhalidwe uliwonse wosakhala wabwino uyenera kufotokozedwa mwachangu.

3. Ikani gasket:

Onetsetsani kuti gasket ikugwirizana ndi kukula kwake ndi zinthu zomwe zafotokozedwa;

Yang'anani gasket kuti muwonetsetse kuti palibe zolakwika;

Mosamala ikani gasket pakati pa flanges awiri;

Onetsetsani kuti gasket ili pakati pa flanges;

Osagwiritsa ntchito zomatira kapena zomatira pokhapokha ngati malangizo oyika gasket akuyitanitsa;gwirizanitsani nkhope za flange kuti gasket isabooledwe kapena kukanda.

4. Patsani mafuta pamalo opanikizika:

Mafuta ofunikira okha kapena ovomerezeka okha ndi omwe amaloledwa kugwiritsidwa ntchito pa malo opangira mphamvu;

Ikani mafuta okwanira pamalo onyamula a ulusi wonse, mtedza ndi ma wacha;

Onetsetsani kuti mafutawo sakuipitsa pa flange kapena gasket.

5. Ikani ndi kumangitsa mabawuti:

Nthawi zonse gwiritsani ntchito chida choyenera

Gwiritsani ntchito wrench ya torque, kapena chida china chomangirira chomwe chimayang'anira ntchitoyi;

Funsani ndi dipatimenti yaukadaulo ya opanga zisindikizo za zofunikira ndi malamulo a torque;

Mukamangitsa nati, tsatirani "mtanda-symmetrical mfundo";

Mangitsani mtedza molingana ndi masitepe asanu awa:

1: Kumangirira koyambirira kwa mtedza wonse kumachitidwa pamanja, ndipo mtedza waukulu ukhoza kutsekedwa ndi wrench yaing'ono yamanja;

2: Limbani mtedza uliwonse pafupifupi 30% ya torque yonse yofunikira;

3: Limbani mtedza uliwonse pafupifupi 60% ya torque yonse yofunikira;

4: Mangitsaninso mtedza uliwonse pogwiritsa ntchito "cross symmetry mfundo" kuti mufikire 100% ya torque yofunikira ya nkhuni zonse;

Zindikirani:Kwa ma flanges akulu akulu, masitepe omwe ali pamwambapa amatha kuchitidwa nthawi zambiri

5: Limbani mtedza wonse umodzi ndi umodzi molunjika kamodzi kokwanira.

6. Limbaninso mabawuti:

ZINDIKIRANI:Funsani dipatimenti yaukadaulo ya opanga zisindikizo kuti mupeze chitsogozo ndi upangiri wakulimbitsanso mabawuti;

Ma gaskets osakhala aasibesitosi ndi ma gaskets okhala ndi zida za mphira zomwe zakhala zikugwiritsidwa ntchito pa kutentha kwakukulu sayenera kuzimitsidwanso (pokhapokha zitanenedwa mwanjira ina);

Zomangira zomwe zalandira kutentha kwa dzimbiri zimayenera kuzimitsidwanso;

Kulimbitsanso kuyenera kuchitika pa kutentha kozungulira komanso kuthamanga kwa mumlengalenga.
