Kuchuluka kwa ntchito ndi zofunikira zaukadaulo za mavavu apamagetsi pokonza kuwonongeka kwa zida mu zida zotumizira ma valve (I)

Njira zomatira zolowetsa mano. Choyamba muyenera kuchotsa dzino losweka, ndi kukonzedwa mu dovetail poyambira pa dzino muzu, ntchito zinthu zomwezo pokonza chidutswa latsopano dzino mu dovetailed, kugwirizana ndi poyambira dovetail wa zida pa, kusunga 0.1 ~ 0.2 mm chilolezo, ndi kupanga Machining latsopano. Dzino, khalani ndi chilolezo chomaliza, mutatha kugwirizana kwambiri ndi mano atsopano ndi malo otsetsereka, pangani template ya mano a gear, ndiyeno mutsirizitse mano atsopano, Mpaka chitsanzocho chikugwirizana ndi mano. Njirayi ndi yoyenera kwa zida zomwe sizikuyenda bwino ndi kuwotcherera.
Chithunzi 7-9 chikuwonetsa momwe mungakonzere mano owonongeka a giya.
Chithunzi 7-9 chikuwonetsa momwe mungakonzere mano owonongeka a giya
1. Kukonza njira ya munthu aliyense dzino kuwonongeka zida
(1) Njira zomatira zolowetsa dzino. Choyamba muyenera kuchotsa dzino losweka, ndi kukonzedwa mu dovetail poyambira pa dzino muzu, ntchito zinthu zomwezo pokonza chidutswa latsopano dzino mu dovetailed, kugwirizana ndi poyambira dovetail wa zida pa, kusunga 0.1 ~ 0.2 mm chilolezo, ndi kupanga Machining latsopano. Dzino, khalani ndi chilolezo chomaliza, mutatha kugwirizana kwambiri ndi mano atsopano ndi malo otsetsereka, pangani template ya mano a gear, ndiyeno mutsirizitse mano atsopano, Mpaka chitsanzocho chikugwirizana ndi mano. Njirayi ndi yoyenera kwa zida zomwe sizikuyenda bwino ndi kuwotcherera.
(2) Kuwotcherera njira ya mano. Njirayi ndi yoyenera zida zogwiritsira ntchito kuwotcherera bwino, ndipo njira yake yokonzanso ndiyofanana ndi njira yolumikizira mano.
(3) Njira yophatikizira mulu. Mu wosweka dzino kubowola pogogoda, ophatikizidwa pa milu imodzi kapena angapo bawuti, ndi surfacing njira mu wosweka dzino lotulukira dzino latsopano, ***, kukonzedwa mu dzino lomwelo monga choyambirira dzino.
2. Kukonza fracture ya zida
Mu chipangizo chotumizira valavu, ngati giya ikusweka, iyenera kusinthidwa ndi gawo latsopano lopuma. Ngati palibe gawo latsopano lopuma kwakanthawi, litha kukonzedwa molingana ndi njira yomwe yawonetsedwa pa Chithunzi 7-10.
Kukonza kuthyoka kwa zida (1) Kuthyoka kwa zida zosweka kumasinthidwa kukhala poyambira, kenako zida zosweka zimayikidwa mu giya kuti zichiritsidwe, ndikuwotcherera pamalopo.
(2) nsonga yokhotakhota ya mbale yolimbikitsa imapangidwa pankhope ziwiri za m'mphepete mwa zida. Kunja kwa poyambira kuyenera kukhala kocheperako 5mm kuposa m'mimba mwake kwa mizu yozungulira, ndipo mkati mwake ndi wocheperako kuposa m'mimba mwake. Kuzama kwa poyambira kumadalira makulidwe a giya, nthawi zambiri pakati pa 3 ndi 6mm.
(3) Kukula kwa clamping groove kudzapambana, ndipo galimotoyo idzapanga mphete ziwiri zolimbitsa. Mphete ziwiri zolimbikitsazo zidzagwedezeka ndikukhazikika muzitsulo zokhotakhota za nkhope ziwiri.
Kuchuluka kwa ntchito ndi zofunikira zaukadaulo wa ma valve opangira magetsi (1) Mulingo uwu umanena za kuthamanga ndi kutentha kwa ma valve apamagetsi ndi zofunikira zonse za zida, kapangidwe, kuyendera, kuyika chizindikiro, kulongedza, kusungira, mayendedwe, zikalata zotumizira, ndi zina zambiri, ndi imapereka chitsogozo cha kuyitanitsa zofunika. Zida za valve ziyenera kusankhidwa malinga ndi momwe zimagwiritsidwira ntchito komanso zofunikira pakupanga; Maboti, mtedza ndi zinthu zina zomangira ziyenera kusankhidwa malinga ndi kugwiritsa ntchito kuthamanga ndi kutentha. Posankha zipangizo zonyamulira mbali za chipolopolo, kutentha kwakukulu kwa ntchitoyo kudzafotokozedwa mu Zowonjezera C. Mulingo uwu umapereka zofunikira zochepa kapena zochepa zopangira ma valve, koma sizomwe zimapangidwira.

Muyezo uwu umanena za kuthamanga ndi kutentha kwa ma valve apamagetsi ndi zofunikira zonse za zida, kapangidwe, kuyang'anira, kuyika chizindikiro, kuyika, kusungirako, mayendedwe, zikalata zobweretsera, ndi zina zambiri, ndipo zimapereka chiwongolero choyitanitsa.
Mulingo uwu umagwira ntchito pamitundu yonse ya mavavu omwe amagwiritsidwa ntchito pamagetsi amagetsi a soda pansi pazigawo izi:
- Kuthamanga mwadzina sikuposa 42MPa, kutentha kwakukulu kwa ntchito sikupitirira 450 ℃;
- Kuthamanga kwa ntchito sikupitirira 26MPa, kutentha kwakukulu kwa ntchito sikupitirira 540 ℃;
- Kuthamanga kwa ntchito sikupitirira 6MPa, kutentha kwakukulu kwa ntchito sikupitirira 570 ℃
2 Zolemba zodziwika bwino
Zomwe zili m'malemba otsatirawa zikuphatikizidwa muyeso lapadziko lonse lapansi potengera. Zosintha zonse zotsatira (kupatulapo zolakwika) kapena kusinthidwa kwa zilolezo zakale sizigwira ntchito pa Mulingo wapadziko lonse uwu. Komabe, omwe akuchita mgwirizano pansi pa International Standards akulimbikitsidwa kuti afufuze kupezeka kwa *** mitundu ya zolembazi. *** Mabaibulo omwe sanatchulidwe ndi nthawi amagwira ntchito pa Mulingo wapadziko lonse uwu.
