Silicon yangirika cyane irwanya ibyuma bya valve

Icyuma kinini cya silicon cyangirika cyuma cyuma cyibikoresho bya valve Iki gipimo cyerekana ibisabwa bya tekiniki, uburyo bwikizamini, amategeko yo gutoranya no kugenzura, gushyiramo ikimenyetso, gupakira, kubika no gutwara ibisabwa kugirango ibyuma bya silicon byangirika byangirika. Ibipimo ngenderwaho birakoreshwa kuri silikoni yo hejuru yangirika ikarishye hamwe na silicon irimo 10, 00% ~ 15. 00%. Igishushanyo cyerekana ibisobanuro, imiterere nubunini, amabwiriza yo guta isuku, ibishushanyo byerekana ibipimo byingenzi no gutanga kwihanganira ibipimo byose. Niba usaba atanga icyitegererezo, ingano ya casting igomba kuba ijyanye nubunini bwagenewe icyitegererezo. Niba ikizamini cya hydraulic gisabwa, kandi niba aribyo, igitutu cyikizamini hamwe n’ibishobora kwemerwa bigomba kwerekanwa. urwego Iki gipimo cyerekana ibisabwa bya tekiniki, uburyo bwo gupima, amategeko yo gutoranya no kugenzura, gushyiramo ikimenyetso, gupakira, kubika no gutwara ibisabwa kugirango silikoni yangirika yangirika. Ibipimo ngenderwaho birakoreshwa kuri silicon yo hejuru yangirika ikarishye hamwe na silicon irimo 10, 00% ~ 15. 00%. Inyandiko isanzwe yamagambo Amagambo ari mu nyandiko akurikira ahinduka ingingo yiyi Standard ukoresheje iyi Standard. Ku matariki yatanzwe, ibyahinduwe byose (ukuyemo erratum) cyangwa ibyahinduwe ntabwo bikurikizwa kuriyi ngingo ngenderwaho; icyakora, impande zombi zumvikanyweho niki gipimo zirashishikarizwa gukora iperereza ku kuboneka kwa *** inyandiko. Kubisobanuro bitarondoreka, verisiyo zabo zirakoreshwa muriki gipimo. Ibisobanuro byamakuru Ibisobanuro bikurikira bigomba gutangwa nuwabisabye: a) Umubare usanzwe wo kurangiza. b) ikirango kinini cya silicon. c) Umubare w'abakinnyi. d) Gutera ibiro. e) Igishushanyo cyerekana ibisobanuro, imiterere nubunini, amabwiriza yo guta isuku, ibishushanyo byerekana ibipimo byingenzi no kwihanganira ibipimo byose. Niba usaba atanga icyitegererezo, ingano ya casting igomba kuba ijyanye nubunini bwagenewe icyitegererezo. Amahitamo akurikirana amakuru: a) Imiterere yo kuvura ubushyuhe bwa casting mugihe cyo kubyara; b) Niba guha uwasabye raporo yisesengura ryimiti; c) Niba hakenewe ikizamini cyo kunama; d) Niba hakenewe ikizamini cya hydraulic, kandi niba aribyo, igitutu cyikizamini hamwe nibishobora kumeneka bigomba kwerekanwa. e) Gupakira ibintu bidasanzwe, gushyira akamenyetso, nibindi. Uburyo bwo kubyaza umusaruro Keretse niba byavuzwe ukundi, uburyo bwo gushonga hamwe na casting bizagenwa nuwabitanze. Icyifuzo cya tekiniki Icyiciro hamwe nubumara bwibikoresho bya silicon yangirika byangirika byicyuma Urwego rwo kwerekana urwego rwicyuma kinini cya silicon rushobora kwangirika ibyuma bihuye nibiteganijwe muri GB / T 5612, bigabanijwemo ibyiciro bine. Icyuma kinini cya silicon cyangirika cyicyuma hamwe nibigize imiti reba Kwemera ibyuma bya silicon yangirika byangirika bigomba gushingira kubigize imiti, bigomba kubahiriza ibivugwa mu mbonerahamwe ya 1. ibyuma muri rusange ntabwo bifatwa nkibyingenzi byo kwemerwa. Niba bisabwa nuwabisabye, inkoni yikizamini igomba gukorerwa ikizamini cyo kugunama kugirango hamenyekane imbaraga zunamye no gutandukana, kandi ibisubizo byikizamini bigomba kubahiriza ibivugwa mu mbonerahamwe ya 2. ibikoresho byicyuma bivunaguye, muburyo bwimiterere yabakinnyi bayo ntibigomba kuba bityaye kandi bikarishye byambukiranya igice. Uburinganire bwa geometrie nubunini bwa casting bigomba guhuza nigishushanyo cyangwa ibisabwa bya tekiniki wabasabye. Niba uwasabye adafite ibisabwa byihariye kubijyanye no kwihanganira ibipimo, hazakurikizwa ingingo zijyanye na GB / T 6414. Ibikinisho bigomba guhanagurwa, gutunganyirizwa "inyama" nyinshi, kuvanaho riser, igufwa ryibanze, umucanga wibumba hamwe nigisigara cyimbere cyimbere, nibindi. cyangwa ibisabwa bya tekinike yumuguzi cyangwa amasezerano yo gutumiza hagati yimpande zombi. Hejuru hejuru: silikoni ndende yangirika yangiza ibyuma bya valve (I) Ikizamini cyikizamini Ikizamini cyo kugonda icyuma kinini cya silicon cyangirika cyuma cyuma gifata umurongo umwe wikizamini ufite diameter ya 30mm nuburebure bwa 330mm udakoresheje imashini. Ibisobanuro byayo byerekanwe ku gishushanyo cya 1. Igice: milimetero Icyitonderwa: Ingano isabwa yo guteramo ibizamini igomba gukonjeshwa kugeza kuri 540 ℃ mu ifu mbere yuko umusenyi ugwa, kandi imihangayiko isigaye igomba kuvaho mbere yikizamini cyo kunama. Inkoni imwe yikizamini cyo gusuka igomba gusukwa mugice kimwe cyicyuma cyamazi kimwe na casting (ibipapuro byibanze nibisoza ntibishobora gukoreshwa). Muburyo bumwe bwo gutara, inkoni nyinshi zipimisha zirashobora gusukwa icyarimwe, kandi inzira yerekanwe irerekanwa mumashusho 2. Igice: milimetero Geometrike hamwe no kwihanganira ibipimo Byinshi bya silikoni yangirika irwanya ibyuma ni ubwoko bwibyuma byoroshye, kandi bikarishye inzibacyuho yinzibacyuho ntigomba gusabwa muburyo bwimiterere yabakinnyi bayo. Uburinganire bwa geometrie nubunini bwa casting bigomba guhuza nigishushanyo cyangwa ibisabwa bya tekiniki wabasabye. Niba uwasabye adafite ibisabwa byihariye kubijyanye no kwihanganira ibipimo, hazakurikizwa ingingo zijyanye na GB / T 6414. Kugabanya ibiro Niba nta cyifuzo kidasanzwe cyo guta ibiro, hagomba gukurikizwa ingingo zijyanye na GB / T 11351. Ubwiza bwubuso Ubuso bwubuso bwa casting bugomba guhuza na GB / T 6061.1 cyangwa ibishushanyo bisabwa cyangwa ibisabwa bya tekiniki. Ibikinisho bigomba guhanagurwa, gutunganyirizwa "inyama" nyinshi, kuvanaho riser, igufwa ryibanze, umucanga wibumba hamwe nigisigara cyimbere cyimbere, nibindi. cyangwa ibisabwa bya tekinike yumuguzi cyangwa amasezerano yo gutumiza hagati yimpande zombi. Inenge ya Casting Ntihazabaho inenge ya casting igabanya imbaraga kandi yangiza isura yibicuruzwa. Inenge zemewe nuburyo bwo kwambara byemeranijwe n’ababuranyi. Kuvura ubushyuhe Ubushyuhe bwinshi bwa silicon busanzwe bukoreshwa muburyo bwo kuvura ubushyuhe (kugirango ukureho imihangayiko isigaye). Kubito bito byuburyo bworoshye, niba byatanzwe nkabakinnyi, impande zombi zigomba kubyemera. Abakinnyi bagomba kuvura ubushyuhe kugirango bakureho imihangayiko isigaye. Niba uwasabye adafite ibyo asabwa bidasanzwe, gutora birashobora gukorwa muburyo bukurikira: Gutera umusenyi wumusenyi muburyo bushyushye butukura, kurandura vuba uburyo bwose bwo kurwanya imashini kugabanuka kubusa, kurandura ibyago, gutukura bishyushye bitunganijwe neza. itanura rishyushya hejuru ya 600 ℃, hanyuma rishyuha buhoro, ugereranije ubushyuhe buke bwa 870 ℃. Ku bushyuhe buri hejuru ya 870 ℃, ukurikije ubugari bunini bwurukuta rwa casting, igihe cyo gukingirwa kigomba kuba 1.h / 25mm, ariko igihe ntarengwa cyo gukingirwa ntigomba kuba munsi ya 2h. Noneho ikonjeshwa ku muvuduko utarenze 55 ℃ / 15 min. Ikonjeshwa kugeza 205 ℃ hamwe nitanura numwuka bikonje mubushyuhe busanzwe. Icyifuzo kidasanzwe Niba uwasabye afite ibisabwa byo gupima magnetique, gupima ultrasonic, gupima X-ray, nibindi, uwasabye nuwabisabye agomba kuganira no gushyira mubikorwa akurikije ibivugwa na GB / T 9444, GB / T 7233 na GB / T 5677. Uburyo bwikizamini Isesengura ryimiti Ibisanzwe, ibintu cyangwa ubundi buryo bwibikoresho biremewe ariko bigomba kuba bisanzwe kugirango bitange ibisubizo bimwe. Uburyo busanzwe bwo gutoranya imiti bugomba gukorwa hakurikijwe GB / T 20066. Isesengura ryakozwe na karubone, silikoni, manganese, sulfure na fosifore mu bigize imiti ryabazwe hakurikijwe GB / T 20123 cyangwa GB / T 223.69, GB / T 223.60, GB / T 223. 58 cyangwa GB / T 223. 64, GB / T 223. 3 cyangwa GB / T 223. 59 cyangwa GB / T 223. 61, GB / T 223. 53 Chrome, urufunguzo, ubukemurampaka bwumuringa isesengura rizakorwa hakurikijwe GB / T 223.11 cyangwa GB / T 223.12, GB / T 223.26, GB / T 223.18 cyangwa GB / T 223.19 cyangwa GB / T 223.53. Uburyo bwo gutoranya ibintu bukorwa hakurikijwe GB / T 5678 na GB / T 14203. Uburyo bwo gusesengura ibintu bugomba gukorwa hakurikijwe GB / T 20125.
