Timathandiza dziko kukula kuyambira 1991

Zinthu zingapo zomwe zimafunikira chidwi pakukhazikitsa ma gaskets

Gasket ndi gawo lokhazikika lotsekera lomwe limathetsa "kuthamanga, kutulutsa, kutuluka, ndikudontha". Popeza pali malo osindikizira osasunthika, kutengera kusindikiza kosasunthika kumeneku, ma gaskets osunthika, ma gaskets elliptical, ma gaskets a mandala, ma gaskets, ma gaskets amadzimadzi, ma O-mphete, ndi ma gaskets osiyanasiyana osindikiza. Kukhazikitsa kolondola kwa gasket kuyenera kuchitidwa pomwe cholumikizira cha flange kapena cholumikizira cholumikizidwa, malo osindikizira osasunthika ndi gasket mosakayikira amafufuzidwa, ndipo magawo ena a valavu asadutse.

1. Musanatseke gasket, perekani ufa wosalala wa graphite kapena ufa wa graphite wothira mafuta (kapena madzi) pamalo osindikizira, gasket, ulusi ndi bawuti ndi mbali zosinthasintha za nati. Gasket ndi graphite ziyenera kukhala zoyera.

2. Gasket iyenera kukhazikitsidwa pamalo osindikizira kuti ikhale yokhazikika, yolondola, kuti isasocheretsedwe, kuti isapitirire mchimbudzi kapena kupumula paphewa. Mzere wamkati wa gasket uyenera kukhala wokulirapo kuposa dzenje lamkati losindikizira, ndipo gawo lakunja liyenera kukhala locheperako pang'ono kuposa gawo lakunja la kusindikiza, kuti zitsimikizire kuti gasket ndiyoponderezedwa.

3. Mbali imodzi yokha ya gasket ndi yomwe imaloledwa kuyika, ndipo siyiloledwa kuyika zidutswa ziwiri kapena zingapo pakati pa malo osindikizira kuti athetse kusowa kwa mpata pakati pa malo awiri osindikizira.

4. Gasket lovulaza liyenera kusindikizidwa kuti mphete zamkati ndi zakunja za gasket zikulumikizane, ndipo malekezero awiri a gasket sayenera kulumikizana ndi pansi pa poyambira.

5. Kuyika O-mphete, kupatula kuti mphete ndi poyambira ziyenera kukwaniritsa zofunikira pamapangidwe, kuchuluka kwa kupanikizika kuyenera kukhala koyenera. Kutsetsereka kwazitsulo zopanda pake O-mphete nthawi zambiri kumakhala 10% mpaka 40%. Kuchuluka kwa mapindikidwe a mphira O-mphete ndizoyambira. Kusindikiza kosasunthika kumtunda ndi 13% -20%; malo osindikizira osasunthika ndi 15% -25%. Pakukakamizidwa kwamkati mwamkati, kupsinjika kwakanthawi kuyenera kukhala kwakukulu mukamagwiritsa ntchito zingalowe. Pogwiritsa ntchito chiyembekezo chotsimikizira kuti kusindikiza, zocheperako ndizocheperako, zimakhala bwino, zomwe zitha kukulitsa moyo wa O-ring.

6. Valavu iyenera kukhala pamalo otseguka gasket isanayikidwe pachikuto, kuti isakhudze kuyika ndikuwononga valavu. Mukatseka chivundikirocho, gwirizanitsani malowo, ndipo musalumikizane ndi gasket pokankha kapena kukoka kuti mupewe kusunthika ndi zokopa za gasket. Mukasintha momwe chivundikirocho chikuyendera, muyenera kukweza chivundikirocho pang'onopang'ono, kenako nkuchiyika bwinobwino.

7. Kuyika ma gaskets omangirizidwa kapena omangirizidwa kuyenera kukhala kotero kuti ma gaskets ali pamalo opingasa (chivundikiro cha gasket cholumikizira ulusi sichiyenera kugwiritsa ntchito zingwe zopopera ngati pali wrench). Chomangika chikuyenera kutengera njira yofananira, yosinthira, komanso momwe imagwirira ntchito, ndipo ma bolts akuyenera kumangiriridwa bwino, osamalika komanso osamasuka.

8. Gasket lisanapanikizike, kupsinjika, kutentha, mawonekedwe apakatikati, ndi mawonekedwe a gasket akuyenera kumvetsetsedwa bwino kuti adziwe mphamvu yolimbikira. Mphamvu yolimbikitsayo iyenera kuchepetsedwa momwe zingathere pokhapokha kuyesa kukakamizidwa sikutuluka (mphamvu yolimbitsa kwambiri isanapweteke gasket ndikupangitsa gasket kutaya mphamvu).

9. Gasket ikakhazikika, ziyenera kuonetsetsa kuti pali mpata wolumikizira chisanachitike cholumikizira, kuti pakhale malo olimbitsira pomwe gasket ikudontha.

10. Mukamagwira ntchito pamalo otentha kwambiri, ma bolts amamva kutentha kwambiri, kupumula kwakanthawi, ndikuchulukirachulukira, zomwe zimapangitsa kuti pakadumphe gasket ndikufunika kutenthetsa. M'malo mwake, pansi pamawonekedwe otentha, ma bolts adzachepa ndipo amafunika kuti amasulidwe ozizira. Kutentha kotentha ndiko kukakamiza, kumasula kuzizira ndikutsitsimula, kutenthetsa kozizira komanso kumasula kuzizira kuyenera kuchitidwa mukapitiliza kutentha kwa maola 24.

11. Gasket yamadzi ikagwiritsidwa ntchito posindikiza, malo osindikiza ayenera kutsukidwa kapena kuthiridwa pamwamba. Malo osindikizira osanjikiza ayenera kukhala osasinthasintha akamagaya, ndipo zomatira ziyenera kugwiritsidwa ntchito wogawana (zomatira zizigwirizana ndi magwiridwe antchito), ndipo mpweya uyenera kuchotsedwa momwe zingathere. Mzere womata nthawi zambiri umakhala 0,1 ~ 0.2mm. Chingwe cholumikizira ndichofanana ndi malo osindikizira osanja. Malo onse olumikizirana ayenera kukutidwa. Mukakulowetsamo, iyenera kukhala yoyimirira kuti ithetse mpweya. Guluu sayenera kukhala wochuluka kwambiri kuti tipewe kutayikira ndi kuipitsa mavavu ena.

12. Mukamagwiritsa ntchito tepi ya PTFE yosindikiza ulusi, gawo loyambira mufilimuyo liyenera kutambasulidwa ndi kumata kumtambo; ndiye kuti tepi yochulukirapo poyambira iyenera kuchotsedwa kuti filimuyo ikamatirire ulusiwo kukhala mphete. Kutengera kusiyana kwa ulusi, nthawi zambiri imavulazidwa kamodzi kapena katatu. Njira yolowera iyenera kutsatira njira yolumikizira, ndipo kumapeto kwake kuyenera kukhala mwangozi ndi poyambira; pang'onopang'ono imakoka kanemayo mosakanikirana, kuti makulidwe a filimuyo akhale ofanana. Musanalowe mkati, kanikizani kanemayo kumapeto kwa ulusi kuti kanemayo akhoza kulowetsedwa mu ulusi wamkati limodzi ndi zomangira; chowongolera chiyenera kukhala chochedwa ndipo mphamvu iyenera kukhala yofanana; osasunthanso mukamangitsa, ndipo pewani kutembenuka, apo ayi kudzakhala kosavuta kutayikira.
