Iyo abantu benshi bumvise 'ibyuma bitagira umuyonga', bashushanya icyuma kibengerana, kitangirika. Ngiyo imyumvire ya mbere itari yo. Ukuri kurimo ibintu byinshi kandi birashimishije. Ntabwo ari ibikoresho gusa; ni ibijyanye n'imiterere y'ibinyampeke biva muri casting, kwihanganira imashini, urwego rwihariye rurwanya cocktail yimiti, hamwe nubucuruzi byanze bikunze. Nabonye imishinga myinshi yerekana rusange 304 cyangwa 316 valve kuri buri kintu, gusa kugirango mpure nikibazo kitaragera mumurima. Igishishwa ni isura gusa. Inkuru nyayo iri muri metallurgie nubukorikori bwo gukora inyuma yacyo.
Urufatiro: Itangirana na Casting
Ntushobora gukora imashini yizewe kuva muke. Aha niho uburambe bwimyaka mirongo, nkibyo ubona mubikorwa bimaze igihe, bifite akamaro. Ndibuka gusuzuma icyiciro cya ibyuma bitagira umuyonga imibiri kumurongo wo kugaburira imiti. Ku mpapuro, bari 316L. Biboneka ko bari bameze neza. Ariko mugihe cyo kwipimisha irangi, urusobe rwa micro-shrinkage porosity rwerekanwe, mugice cyurukuta rukomeye. Icyo cyiciro cyari kigenewe ibidukikije bya chloride. Byaba ari ukumena gutegereza gutegereza kubaho. Igikorwa cyo kugenzura ibikorwa - uburyo bayobora ubushyuhe bwo gusuka, ibikoresho bibumba, nigipimo cyo gukonja - nibintu byose. Isosiyete imaze imyaka isaga 30 mumikino yo gukina, nka Qingdao Qiangsenyuan Technology (QSY), yaba yarahinduye izo mpinduka binyuze mubisubiramo gusa. Ibyibandwaho kuri shell mold no gushora imari ni urufunguzo rwa valve; ubu buryo butanga uburinganire bwuzuye hamwe nubuso burangirira kubice byimbere imbere ugereranije nuburyo bumwe bwo guta umucanga, bivuze ko gutunganya bike hamwe nibicuruzwa byanyuma.
Guhitamo ibikoresho kuri stade ni ikindi cyemezo kidahwitse. Ibyuma bitagira umwanda nicyiciro kinini. Kumurongo wamazi usanzwe, CF8 (abakinnyi bahwanye na 304) irashobora kuba ihagije. Ariko kuri offshore porogaramu hamwe na spray yumunyu uhoraho, urareba super duplex urwego, ikintu nka F55. Ingorabahizi yo gukina irasimbuka cyane. Ibigize ibivangwa bigomba gufatwa mumadirishya ifunze cyane, kandi kuvura ubushyuhe nyuma yo guterwa kugirango uburinganire bwa ferrite-austenite burakomeye. Nabonye indanga zimeneka mugihe cyo gutunganya kuko cycle yo kuvura ubushyuhe yari yazimye kuri dogere nkeya. Nibutsa ko imikorere ya valve ifunze kera mbere yuko igera ku ntebe yinteko.
Aha niho umwihariko muri alloys, nka nikel-ishingiye, uba ngombwa. Twari dufite umushinga urimo umwuka wa acide ushushe. Bisanzwe 316L yaba yarashonje. Igisubizo cyari umubiri wa valve waturutse kuri Alloy 20Cb3. Ubushobozi bwumushinga bwo gukora ibintu nkibi ntabwo ari kuruhande; nubushobozi bwibanze bwo guhangana na serivisi yangirika. Ntabwo ari ukugira umusemburo kurutonde; ni ukumenya kujugunya udateye amarira ashyushye cyangwa amacakubiri.
Imashini: Aho Precision ihurira nibikorwa
Gukina ni igishusho kitoroshye. Imashini izana ubuzima. Kandi dore ukuri gufatika: ingamba zo gutunganya a ibyuma bitagira umuyonga umubiri uratandukanye nuwo guhagarika ibyuma byoroheje. Akazi kadafite akazi. Niba ibikoresho byawe bidakaze, umuvuduko wawe hamwe nibiryo byawe ntabwo ari byiza, uzatwika hejuru aho kuyikata, ukore urwego rukomeye, ruvunitse rushobora gutangiza ibice munsi yumuvuduko ukabije. Ibi nabyize inzira igoye hakiri kare, mbyara urutonde rwamarembo ya valve yometse kandi ifata mugihe cyibizamini byambere byumuvuduko. Kurangiza byari byiza, ariko bikora neza.
Ibigo bitunganya CNC bitanga isubirwamo, ariko ubumenyi bwa programu nibyo bituma bwizewe. Urukurikirane rwibikorwa. Wakuye umufuka wintebe mbere cyangwa nyuma yo gucukura umwobo wuruti? Nigute ushobora guhuza umubiri umeze nkudasanzwe kugirango urangize kurangiza kumaso ya flange utarinze guhangayika? Kubintu byinshi bigizwe nibyuma byinshi, iyi iba puzzle ya 3D. Amaduka afite uburambe bwimbitse bwa CNC, ushobora gupima uhereye kubice byabo kurubuga nka https://www.tsingtaocnc.com, ukunda kuba ibyo bikorwa byashinze imizi. Ntabwo bakata ibyuma gusa; barimo gucunga ibibazo bisigaye no gukomeza imibare yerekanwe muburyo bwinshi.
Noneho hariho iherezo. Microfinish ya 32 Ra ku ntebe yumupira wumupira irashobora kuba spec'd. Kugera kubyo hejuru yubutaka butagira umwanda, burigihe, hejuru yamajana, ni ubukorikori. Bikunze kubamo guhuza CNC guhindukira hanyuma igikorwa cyihariye cyo gukubita cyangwa gusya. Nasuye amahugurwa aho iyi ntambwe yanyuma iracyakorwa nabatekinisiye bamenyereye bashobora 'kumva' kurangiza. Nuruvange rwa CNC igezweho nubuhanga bwitondewe akenshi butanga ibimenyetso byizewe bifatika.
Inteko & Kugerageza Imitego
Aha niho ibice byiza bishobora guhinduka valve mbi. Inteko isa nkiyoroshye: shyira umubiri, trim (stem, umupira, intebe), hamwe na kashe hamwe. Ariko satani muburyo burambuye. Ikosa risanzwe ni ukurenza urugero gukurikira gland kumurongo uzamuka. Ibi bihindura ipaki, bigatera ubushyamirane bukabije kuruti, kandi biganisha ku kwambara imburagihe hamwe na valve igoye gukora. Ibipimo bya torque birahari kubwimpamvu, nyamara akenshi birengagizwa hasi kumaduka bihutira kurangiza ibyateganijwe.
Kwipimisha nubundi buryo butandukanye. Ikigeragezo cya hydrostatike ni ibisanzwe, byanze bikunze. Ariko ikizamini kirimo ikizamini cyicyicaro cyigice cyo gufunga valve? Kuri serivisi zikomeye, igomba. Ndibuka urubanza aho icyiciro cya ibyuma globe valve yatsinze ikizamini cya shell ariko yamenetse nabi mugupimisha intebe. Intandaro yaturutse ku kudahuza gato mugihe cyo gusya kwa nyuma kwa disiki nintebe - ikibazo ikizamini cyicyicaro gusa cyagaragaza. Uruganda rukomeye ruzagira protocole yo kugerageza, ntabwo ari igitutu kimwe gusa.
Reka tuganire kubyerekeye isuku. Kuri serivisi ya ogisijeni cyangwa imiti ikoreshwa, ibi nibyingenzi. Amavuta, umukungugu, cyangwa ibyuma byose bisigaye mu gutunganya birashobora kuba inkongi y'umuriro cyangwa isoko yanduye. Ahantu ho guteranira hagomba kugenzurwa, kandi uburyo bwo gukora isuku no gupakira bigomba kuba bikaze. Nibintu bikunze kwirengagizwa byigiciro gitandukanya valve yibicuruzwa nibintu byizewe cyane.
Kunanirwa kwisi-Amasomo
Ntakintu cyigisha nko gutsindwa. Twigeze gushiraho urukurikirane rw'imipira 304 idafite umuyonga kumurongo wamazi akonje yikimera (amazi meza). Mu mezi 18, twakemuye ikibazo cyo kumeneka hafi yikibaho na kashe yumubiri. Nyirabayazana yari ruswa. Mugihe 304 ifite imbaraga zo kurwanya ruswa muri rusange, ibidukikije bihagaze hagati yuruti no gupakira, no munsi ya gasketi, byaremye ingirabuzimafatizo za ogisijeni. Chloride yibanze cyane, maze gutobora biratangira. Twahinduye kuri 316 valve hamwe nigishushanyo cyiza cya gaze kandi twerekana uburyo bwo kubungabunga kenshi. Isomo: guhitamo ibikoresho bigomba kubara ibidukikije byihariye, harimo uduce duhagaze hamwe n’imigezi.
Irindi somo ryaturutse ku gusiganwa ku magare. Igice cya casting 316L kumurongo wo kugaruka kumurongo watangiye gucika kumurongo wa bonnet nyuma yumwaka wumurimo. Iperereza ryerekanye umunaniro ukabije. Gukina, nubwo byumvikana, byari bifite ibintu byinshi bya karubone murwego rwo hejuru (kurwego rwo hejuru rwa spec). Ibi, bifatanije nubushyuhe bwihuse no gukonjesha, byateje imvura ya karbide kumupaka wingano, bigabanya guhindagurika. Gukosora kwari ugutanga indangagaciro zifite L-urwego (karubone nkeya) hamwe namateka yo kuvura ubushyuhe. Yashimangiye ko icyemezo cyurupapuro rwimpapuro ari intangiriro, ntabwo ari garanti.
Isoko n'agaciro k'umufatanyabikorwa wihariye
Ibi binzanye gushakisha. Kubona utanga ibicuruzwa bigenzura inzira kuva gushonga kugeza kumaduka yimashini ninyungu nini. Iyo havutse ikibazo, ntuba uguye mumuzinga hagati yimishinga nububiko bwimashini zishinja mugenzi we. Uruganda rukomatanyirijwe hamwe, cyangwa rumwe rufite ubufatanye bwashinze imizi nkisosiyete imaze imyaka 30 ihindagurika kuva ikora imashini itomoye, irashobora gukemura ikibazo mu mizi yacyo. Byari gushyiramo slag muri casting? Igikoresho cyo kunyeganyega mugihe cyo gukora gatanu? Barashobora kubimenya.
Urebye ubushobozi bwabatanga isoko, nkibyavuzwe kuri Qingdao Qiangsenyuan Technology Co., Ltd., ivuga inkuru. Mu myaka irenga mirongo itatu mugukora no gutunganya, gukorana na spekure kuva kumyuma kugeza kuri nikel alloy - ayo mateka yerekana ko bahuye kandi bagakemura byinshi mubintu bya gremlin byihariye. Urubuga rwabo, https://www.tsingtaocnc.com, rwerekana kwibanda kubikorwa byo gukora bikomeye mugukora valve. Iyo ushakisha a ibyuma bitagira umuyonga kubisabwa bisaba, uwo murage utunganijwe ningirakamaro nkibicuruzwa byanyuma. Ni itandukaniro hagati yo kugura igice no kugura igice gifite ubujyakuzimu bwimbitse yakozwe inyuma yacyo.
Ubwanyuma, icyuma cyizewe kitagira umuyonga ni ihuriro ryibyuma byukuri, gutera neza, gutunganya disipuline, no guterana neza. Ni gake cyane amahitamo ahendutse, kuko buri ntambwe igura. Ariko mubikorwa byinganda, ikiguzi cyo gutsindwa - igihe cyo hasi, kurekura ibidukikije, guhungabanya umutekano - bigabanya itandukaniro ryambere ryibiciro. Intego ntabwo ari ukugura valve; ni ukugura igikoresho gifunze, igitutu-imbibi kizakora muburyo buteganijwe mubuzima bwacyo. Kandi ibyo bisaba kureba hejuru yubuso bunoze.
