Inzira yo gukonjesha hamwe nubushyuhe bwo hejuru bikoreshwa mubice byinshi. Kurugero, uburyo bwo gutunganya ubushyuhe ninzira ishyushya ibikoresho byibyuma cyangwa ibicuruzwa byabo kubushyuhe bukenewe, bikonjesha kumuvuduko nuburyo bwatoranijwe, bigahindura imiterere yimbere, kandi bikabona imikorere isabwa. Ubu bwoko bwibikorwa bukoreshwa mubice byinshi byo gutunganya ibicuruzwa, ariko nigute inkoni ya piston ikorerwa ubushyuhe? Nubuhe buryo bwo kuvura ubushyuhe? Yantai Shunfa Ibigize Pneumatic Co., Ltd. irasubiza kuburyo bukurikira.
Intego yo kuzimya no kuvura ubushyuhe ni ukureba niba inkoni ya piston ifite imiterere yubukanishi ihuza imbaraga, ubukana, plastike, hamwe nubukomere neza. Imiterere yimbere ni imwe kandi nziza ya sorbite, itegurwa kuzimya hejuru. Inkoni ndende ya piston piston ifite uburebure bwa 3800-4200 na diameter ya Φ 90- Φ 110mm, kubwibyo ibikoresho byayo byo gushyushya bifata itanura ryo mu bwoko bwa 150KW cyangwa itanura rya 600KW ryahagaritswe bikomeza gushyuha, hamwe n'ubushyuhe bugenzurwa muri zone ebyiri: hejuru no hepfo. Ibipimo byo gutunganya ubushyuhe: Imiyoboro ine ihagarikwa mu itanura rimwe mu itanura ryubwoko bwiza, hamwe nubushyuhe bwo kuzimya 830 ± 10 ℃. Nyuma yo gufata iminota 160, imiyoboro yazimye inshuro ebyiri, hamwe na tebes ebyiri yazimye buri gihe. Kuzenguruka amazi akonje akoreshwa mugukonjesha imiyoboro, ihindagurika hejuru no hepfo mugihe cyo kuzimya kugirango habeho gukonja kimwe kurwego runini. Iyo ikonje igera kuri 100 ℃ (inkoni zisohora umwuka ariko ntizibe), amazi atembera mu itanura ryubwoko bwiza bwo gushyushya.
Noneho imiyoboro ine yashyutswe kuri 550 ± 10 a icyarimwe, ifata iminota 190, hanyuma igashyuha mbere yo gukonjesha amazi. Nyuma yuburyo buvuzwe haruguru kuzimya no kuvura ubushyuhe, imikorere ntabwo ihagaze, kandi ubukana burahinduka hagati ya 210-255HBS. Hariho kandi itandukaniro rikomeye mubukomere hagati yo hejuru, hagati, no hepfo yibice bimwe bya piston. Kandi rimwe na rimwe hariho ubushyuhe bwa buri muntu ufite ubukana butujuje ibyangombwa cyangwa imbaraga nke zisaba kuvurwa. Kuzimya guhindura ibintu ni binini, byongera ingorane zo kugorora no gutunganya imashini. Bitewe no gukomera kwicyuma 45, imiterere yimbere igenzurwa na metallografiya ntabwo ari sorbite imwe kandi imwe, ahubwo ni umubare munini wa sorbite yubusa ibaho hagati yayo, kandi ibice bimwe na bimwe bifite urusobe rwa sorbite na Widmann.
Kugira ngo dukemure ibibazo byavuzwe haruguru, dukoresha guhagarika guhagarika ubushyuhe bwo kuzimya no gutanura itanura ryo kuzimya no gushyushya, hamwe na tebes 2 zashyizwe kuri buri tube. Nyuma yo gushyushya no kubika, itanura rihita rizimya, kandi umuyoboro umwe ukorwa kuri bits kugirango ubushyuhe bumwe. Urebye ko ubushyuhe bwa Ac3 bwibyuma 45 ari 770-780 ℃, kugirango tunonosore ingano kandi tugabanye guhindagurika uko bishoboka kwose, twemeje 790 ± 10 process uburyo bwo kuzimya intercritical kugirango tunonosore ingano ya austenite, kandi tubone noode nziza ya Flat. martensite nyuma yo kuzimya, kugirango uzamure imbaraga nubukomezi bwinkoni ya piston. Kugirango turusheho kugabanya guhindura no kunoza ubukonje bwumuti wokuzimya, twongeyeho 5% -10% byongeweho kuzimya kumazi. Mugihe cyo kuzimya, twakoresheje kandi pompe yamazi azenguruka kugirango duhate igisubizo gikonje kugirango kizenguruke. Ubushyuhe buracyashyuha kuri 550 ± 10 ℃, hamwe nigitekerezo cyo kuzimya nka mbere. Nyuma yo gushyuha, ikonjeshwa namazi kugirango wirinde ko habaho ubwoko bwa kabiri bwubushyuhe bukabije. Nyuma yuburyo bunoze bwo kunoza imikorere, imiterere yimbere ni imwe kandi nziza ya sorbite, hamwe no kuvanaho ferrite nini cyangwa reticular ferrite na Widmann, bikavamo gukomera hamwe nimbaraga zihamye.
