Vermicular cast fer yibikoresho bya valve

Iki gipimo gisobanura amagambo n'ibisobanuro, amanota, ibisabwa bya tekiniki, icyitegererezo no guhagarika ibizamini, uburyo bwo gukora ibizamini, amategeko yo kubungabunga, kuranga ibishushanyo, gupakira, kubika no gutwara ibintu. Uburyo bwo kubyaza umusaruro hamwe nubumara bwa chimique ya vermicular cast bigomba kugenwa nuwabitanze kugirango barebe ko ibikoresho nibikoresho bikenewe bijyanye niki gipimo. Iyo vermicular cast fer ifite imikoreshereze idasanzwe nibisabwa, imiterere yimiti no kuvura ubushyuhe birashobora kumvikana nimpande zombi. Vermicular cast fer igomba kwitabwaho kugira byibura 80% ya grafite ya veritike ku ndege yayo ifite ibipimo bibiri, kandi 20% isigaye igomba kuba igishushanyo mbonera, igishushanyo mbonera, na flake grafite ntigomba kwemererwa.

Vermicular cast Iron

Carbone iri muburyo bwa grafitike ya vermicular yaguye iva mubyuma muri matrice yicyuma.

Kuvura neza

Inzira ikoreramo ibintu byongewemo ibyuma byamazi kugirango bigabanye grafite isa ninzoka mugihe gikomeye.

Gutera urukuta runini

Ubunini bwurukuta runini rwo gukina bivuga ubunini bwigice cyimikorere yubukanishi bwibikoresho byo guteramo cyangwa ubunini bwigice kinini cyakazi cya casting, byemeranijwe nimpande zombi.

ikirango

Urwego rwibikoresho rugomba guhagararirwa hakurikijwe ibisobanuro bya GB / T 5612.

Muri iki gipimo, vermicular graphite cast fer igabanijwemo amanota 5 ukurikije uburyo bwa tekinike yubushakashatsi bwakorewe hamwe nabakinnyi bonyine (reba Imbonerahamwe 1 na Imbonerahamwe 2).

Tegeka amakuru

Ikirango cyo gukina ibikoresho bisabwa na Demander.

Ubunini bwurukuta runini rwibikorwa bya casting nkuko byemeranijwe nimpande zombi.

Ibindi bisabwa bidasanzwe byemeranijweho nimpande zombi.

Umusaruro ninganda

Uburyo bwo kubyaza umusaruro hamwe nubumara bwa chimique ya vermicular cast bigomba kugenwa nuwabitanze kugirango barebe ko ibikoresho nibikoresho bikenewe bijyanye niki gipimo. Iyo vermicular cast fer ifite imikoreshereze idasanzwe nibisabwa, imiterere yimiti no kuvura ubushyuhe birashobora kumvikana nimpande zombi.

Ibisabwa tekinike

Ibikoresho bya tekinike yumukino umwe

Imiterere yubukorikori bwa sample imwe yicyuma cya vermicular cast fer igomba guhuza nibisobanuro biri mumeza 1.

Mubisanzwe, 0.2% yumusaruro imbaraga Rpo ntabwo ikoreshwa nkibanze ryo kwemerwa. Iyo usaba afite ibisabwa byihariye, birashobora kandi kugenwa.

Imbonerahamwe 1 Imikorere yubukorikori bwa sample imwe

Imikorere yubukorikori yabakinnyi

Imiterere yubukorikori bwa vermicular cast yicyitegererezo igomba guhuza nibisobanuro biri mu mbonerahamwe ya 2.

0.2% yumusaruro imbaraga Rpo mubusanzwe ntabwo ikoreshwa nkibanze ryo kwemerwa. Iyo usaba afite ibisabwa byihariye, birashobora kandi kugenwa.

Imbonerahamwe 2 Imikorere yubukorikori bw'icyitegererezo

Imikorere ya mashini yo guta umubiri icyitegererezo

Umwanya wicyuma cya vermicular hamwe nibizamini byo gupimisha ugomba kuzirikana imiterere ya casting nuburyo bwimiterere ya sisitemu yo gusuka, kugirango wirinde ingaruka mbi kumikorere yibice byegeranye, kandi ihame ntabwo ari bigira ingaruka kumikorere yuburyo bwa casting, isura nziza yubukorikori hamwe nubucucike bwibizamini. Guhagarika ikizamini bigomba gukurwa mubice byimibonano mpuzabitsina. Kugirango umenye ingano yicyitegererezo, umuguzi agomba kwereka uwabitanze igice cyingenzi cya casting. Niba uwasabye adafite igitekerezo kibogamye, utanga isoko arashobora gushiraho umwanya wo guca kuri casting no kumenya diameter yicyitegererezo.

Gushiraho: vermicular cast fer kubikoresho bya Valve (I)

Hamwe no guhagarika ikizamini

Imyitozo ifatanyirizwamo ibizamini nayo ni casting zose zicyiciro kimwe zifite ubugari busa.

Mubisanzwe, iyo uburemere bwa casting burenze 2000 kg, naho ubugari bwurukuta ni 30mm ~ 200mm, birahitamo guhuza ikizamini cyo gukina. Iyo uburemere bwa casting burenze 2000kg naho ubugari bwurukuta ni 200mm, ikizamini cyo guteranya kashe kirakoreshwa. Ingano n'umwanya wa basti yikizamini byemeranijwe nimpande zombi.

Keretse niba byateganijwe ukundi nimpande zombi, imiterere nubunini bwikizamini cyo kugerageza cyerekanwe kumashusho

Umwanya wikizamini cyinyongera cyibizamini kuri casting ugomba kuzirikana imiterere ya casting nuburyo bwimiterere ya sisitemu yo gusuka, kugirango wirinde ingaruka mbi kumikorere yibice byegeranye, kandi ntibigire ingaruka kumikorere. ya casting, isura yubwiza bwa casting hamwe nubucucike bwikizamini nkibipimo.

Ibizamini byose byahagaritswe bigomba gushyirwaho ikimenyetso kugirango harebwe niba ubuziranenge bwa casting bushobora gukurikiranwa mubikorwa byose.

Iyo guterana bisaba kuvura ubushyuhe, ibyuma bifatanye bigomba gutandukanywa na casting nyuma yo kuvura ubushyuhe keretse byumvikanyweho ukundi n’ababuranyi. kurambura

Ibisobanuro:

Ubushobozi bwo kurya umucanga bwo gupima ibizamini: andika Ⅰ, Ⅱa na Ⅱb ni mm 40 nto; Andika Ⅲ ntoya 80mm

Icyitonderwa: Kubireba urukuta cyangwa ibyuma, icyitegererezo gishobora gukurwa kuri u12.5mm yikizamini, kandi imikorere yubukanishi irashobora kumvikana nimpande zombi.

Ingano yubunini bwa I na U ni milimetero

Ibisobanuro:

Ikizamini cyo guhagarika ibiryo byo kurya: ubwoko bwa I, andika II nto 40mm; Andika Ⅲ Gitoya 80mm,

Icyitonderwa: Kubintu byoroheje bikikijwe cyangwa byuma, icyitegererezo gishobora gukurwa muri u

Guhagarika ibizamini byumubiri

Imikorere yubukanishi bwigice cyagenwe cya casting igomba kumvikana nimpande zombi. Iyi mirimo igomba gupimwa uhereye ku cyitegererezo cyaciwe mu gice cyagenwe cya casting. Icyitegererezo cya diameter cyemeranijwe nimpande zombi. Ingano yicyitegererezo cyerekanwe muri FIG. 4 na Imbonerahamwe 6

Guhagarika ikizamini bigomba gukurwa mubice byimibonano mpuzabitsina. Kugirango umenye ingano yicyitegererezo, umuguzi agomba kwereka uwabitanze igice cyingenzi cya casting. Niba uwasabye adafite igitekerezo kibogamye, utanga isoko arashobora gushiraho umwanya wo guca kuri casting no kumenya diameter yicyitegererezo.
