Uva umsesane wevalve kwaye uninzi lwabantu, nkqu nabanye ekuthengeni, bafanekisela iwasha enesitampu elula. Yimpazamo yokuqala leyo. Ngokwenyani, loo msesane sisixhobo sokutywina sayo yonke indlela yokutywina kwivalve yokujonga ujingi okanye iwafer. Ijometri yayo, ingqibelelo yemathiriyeli, kunye nokugqiba ngokuthe ngqo kuyala ukuba ufumane ukuvalwa okuqinileyo okanye ukuvuza okungapheliyo okunexabiso eliphezulu. Ndibone iiprojekthi ezininzi kakhulu apho umzimba wevalve wawuchazwe kwimfezeko, kodwa umsesane waphathwa njengento yorhwebo, ekhokelela ekusileleni kwangaphambi kwexesha. Ayisomsesane nje; licandelo elichanekileyo lokutywina.
Umsebenzi ongundoqo kunye neMigibe eqhelekileyo
Umsebenzi wayo ubonakala uqondile: ukubonelela ngomphezulu ofanayo wokutywina wediski okanye ipleyiti edibana nayo xa ukuqukuqela kubuyela umva. Kodwa i-nuance ikwindawo efanayo. Iringi ethe yaphuma kancinane kumcaba-uthi, ngaphaya kwe-0.05mm yokunyamezela kwivalve yee-intshi ezili-10-ayinakutywinwa. Iyakudala indlela yemidiya, ethi kwiinkqubo zempompo ibangele ihamile yamanzi, kwaye kwimigca yenkqubo inokukhokelela kungcoliseko okanye ukwehla koxinzelelo.
Umngxunya endidibana nawo kakhulu yingcinga yokuba ubulukhuni yeyona nto iphambili. Ngokuqinisekileyo, udinga imathiriyeli enzima kunediski ukunqanda ukushumeka. Kodwa umsesane onzima kakhulu, obhityileyo, ngakumbi kwiinkonzo zebhayisikile ze-cryogenic okanye ezishushu, zinokuqhekeka. Ndiyakhumbula imeko kunye nomxhasi usebenzisa iindandatho zentsimbi ye-carbon standard kumgca we-condensate we-steam; ukudinwa kwe-thermal kubangele ukuqhekeka kweenwele kwindawo yokuhlala kwiinyanga nje ezimbalwa. Ukulungiswa kwakungeyonto inzima, kodwa eyona nto yomelela ngakumbi eneempawu ezingcono zobushushu.
Olunye uqwalaselo kukugqiba. Ipolishi yesipili ayisoloko ingcono. Kwizitywina ezithambileyo okanye iidiski ezigqunywe nge-elastomer, okunene ufuna ukuthungwa komphezulu olawulwayo-ixabiso elithile likaRa-ukuvumela itywina ukuba lilume kancinci ngaphandle kokukrazula. Umphezulu ogudileyo ngokugqibeleleyo ngamanye amaxesha unokukhokelela ekutyibilikeni kunye nokuvuza phantsi koxinzelelo oluguquguqukayo.
Ukukhethwa kwezinto eziphathekayo: Konke kumalunga neNkonzo
Kulapho i-30-odd iminyaka ye-Foundry ifana Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) bonisa ixabiso labo. Ukuphosa le ringi akukho malunga nokugalela isinyithi kwi-mold; imalunga nokulawula ukwakheka kweenkozo ukuthintela deformation phantsi komthwalo. Ukusetyenziswa kwamanzi asemgangathweni, umgangatho omhle we-ductile iron okanye i-cast steel cast isebenza. Kodwa oko kusenzeka xa ungena kwindawo emdaka okanye enobushushu obuphezulu, umdlalo uyatshintsha.
Sisebenze kwiprojekthi ebandakanya umgca wokudosa iikhemikhali nomxholo oneasidi epholileyo. Inkcazo yokuqala yayiyeyamakhonkco entsimbi engama-304. Kwakubonakala kusengqiqweni. Nangona kunjalo, i-corrosion ye-pitting yaqala ebusweni bokuhlalisa emva kwexesha elifutshane. Uhlalutyo lokungaphumeleli lwalatha kwi-corrosion kwi-microscopic level. Isisombululo, esiye saphuhlisa ngokubonisana neqela labo lomatshini, yayikukutshintshela kwi-316L enomxholo wekhabhoni ephantsi kwaye sicacise isisombululo sonyango lwe-annealing post-casting ukunyusa ukuxhathisa ukubola. Umahluko kubomi obude wawumangalisa.
Ubungcali babo kwii-alloys ezikhethekileyo, njenge-nickel-based based (cinga i-Inconel 625) okanye i-cobalt-based alloys (njenge-Stellite 6), ibalulekile kwiinkonzo ezigqithisileyo. Kwi-boiler yoxinzelelo oluphezulu lwenkqubo yamanzi apho ukhukuliseko lwe-cavitation ngumbulali, sigqume ubuso bendawo yokuhlala yentsimbi ye-carbon steel kunye ne-Stellite usebenzisa inkqubo yokubeka echanekileyo. Oku kusinike ukuqina kwentsimbi enomgangatho oqinileyo oqinileyo, nokwaziyo ukumelana nokhukuliseko. Zezi ndlela ezixubeneyo ezisombulula iingxaki zehlabathi lokwenyani.
IiNuances zokuSebenza: UkuCala kunye nokuMachining Interplay
Uhambo ukusuka ekugalweni ukuya ekugqityweni jonga iringi yevalvu ibalulekile. Ulwakhiwo olusondeleyo lwe-net-shape oluvela kwiqokobhe elithembekileyo lokungunda okanye inkqubo yotyalo-mali, njengaleyo i-QSY igxile kuyo, inciphisa isibonelelo somatshini. Esi sisitshixo sezinto ezifana nentsimbi okanye i-alloy high-alloy steels, apho ufuna ukugcina izinto eziphathekayo kunye nokunciphisa inkunkuma. Ukususa isiqingatha se-intshi yesitokhwe kwi-alloy eqinile akubizi nje ngexesha lomatshini; inokubangela uxinzelelo.
Ulandelelwano lomatshini lubalulekile. Awunakuvele uyikhuphe kwaye ujongane nayo. Iimpawu zokuxhoma-nokuba yipokotho ehambelana nokushicilela okanye i-groove egciniweyo enentambo-kufuneka yenziwe ngoomatshini kuqala, kumiselwe idatha yakho. Emva koko, kwaye kuphela emva koko, ugqibezela ubuso obubalulekileyo bokutywina. Ndibone amakhonkco apho olu cwangco lubuyiselwe umva, lukhokelela kwindawo entle yokutywina ehambelana ngokupheleleyo nento, ebangela ulungelelwaniso kumzimba wevalvu.
CNC machining consistency is non-negotiable. Kwi-odolo yebhetshi, ukukwazi kwevenkile ukubamba ukunyamezelana kumakhulu amaqhekeza yinto eyahlula icandelo elisebenzayo neliyingxaki. Ukugxila phakathi kwe-OD, indawo yokuhlala, kunye nazo naziphi na iimpawu zokugcina zihlala zingahoywa kwimizobo kodwa ibalulekile nakuxinzelelo kunye nobomi botywino. Iqabane elilungileyo aliyi kucela nje umzobo; baya kubuza malunga noyilo lwevalvu, uhlobo lwediskhi, kunye noxinzelelo lokusebenza ukucebisa kwezi unyamezelo ezingathethwayo.
I-Real-World Application kunye noHlalutyo lokungaphumeleli
Makhe ndichaze intloko ethile. Iziko lombane belifumana ukuvuza okuzingileyo kwiivalvu zaso zokujonga amanzi apholileyo. Iivalvu zahlaziywa ngeediski ezintsha, kodwa ezokuqala jonga amakhonkco evalvu babethwa kancinci nje. Ukuvuza kwaqhubeka. Ekuhlolweni, ubuso obuhlala kwiringi bubonise ipateni encinci, emile okwesitya, mhlawumbi 0.1mm ubunzulu embindini. Yayingabonakali ngeliso kodwa yanele ukwaphula itywina. Oyena nobangela? Amakhonkco okuqala awazange abe lukhuni, kwaye iminyaka yempembelelo yediski ibangele ukuguqulwa kweplastiki. I-Lapping ipholise nje ubume obugogekileyo. Ukulungiswa okufanelekileyo yayikukutshintsha amakhonkco nge-hard-hard. Isifundo: soloko uhlola i-ringi ukuba ithe tyaba kunye neprofayile yomphezulu, hayi nje imikrwelo yomphezulu.
Kwesinye imeko, kwinkqubo ye-ballast yolwandle, iindandatho zichazwe kwi-duplex yensimbi engenasici yokumelana nokubola. Bahlulekile ngaphambi kwexesha ngenxa ye-galling-i-disc yayiza ku-micro-weld ukuya kwindandatho phantsi koxinzelelo. Umcimbi yayikukuba zombini idiski kunye neringi zazinobunzima obufanayo kunye ne-alloy. Ukulungiswa kwakukucacisa into eyahlukileyo, ehambelanayo ye-disc (i-alloy ye-bronze) ukukhusela ukugqoka i-adhesive, ngelixa igcina i-duplex ring ye-corrosion resistance resistance. Ukudibanisa izinto eziphathekayo kubaluleke njengemathiriyeli ngokwayo.
Le ayiyomiba yethiyori. Ziintlobo zeengxaki ezikhokelela ekuphelelweni komnxeba ngo-2 am tsngtaocnc.com-ixabiseke kakhulu. Asingabo nje abathabathi-odolo; bangabasombululi beengxaki abaqondayo ukuba icandelo kufuneka liphile kwinkqubo, hayi nje ukuhlangabezana noshicilelo.
Iingqwalasela zexesha elizayo kunye neengcamango zokuGqukumbela
Ukukhangela phambili, ukuhlanganiswa kwamakhonkco angeyintsimbi okanye afakwe kwintsimbi kuyakhula. Amakhonkco e-PTFE agqunyiweyo okanye nge-ceramic-coated kwiinkonzo ezisulungekileyo okanye ezirhabaxa kakhulu ziya zixhaphaka. Umceli mngeni utshintsha kwiipropati zezinto ezininzi ukuya kwingqibelelo yokubambelela kunye nokuhambelana nokwandiswa kwe-thermal phakathi kwengubo kunye ne-metal substrate. Isiseko sokuphosa kunye ne-machining kufuneka singabinasiphako ukuze ezi zambatho zibambelele ngokufanelekileyo.
Ngaphaya koko, ukunyuka kwemveliso eyongeziweyo kunokubonelela ngezisombululo zamakhonkco ashicilelwe ngokudityanisiweyo aneetshaneli zokupholisa zangaphakathi ezinzulu zobushushu obuphezulu, nangona okwangoku, ukwenziwa kwemveli kunye noomatshini be-CNC kubonelela ngeyona ndlela ilungileyo yokudityaniswa kolwakhiwo, ukusebenza kakuhle kweendleko, kunye nokuveliswa kwevolumu kuninzi lwezicelo zamashishini.
Ke, xa ulandelayo uchaza okanye ukhangela a jonga iringi yevalvu, hamba ngaphaya kwenani lenxalenye. Cinga ngomjikelo opheleleyo womsebenzi: ulwelo, ubushushu obuguqukayo, i-spikes yoxinzelelo, umjikelo ophindaphindiweyo. Emva koko, iqabane kunye nomenzi onobunzulu bubonisa kwimibuzo yabo, kungekhona nje ikhathalogu yabo. Injongo kukuba loo msesane ulityalwe-ukwenza ngokuthembekileyo kangangokuba soze ibe sisizathu somyalelo womsebenzi. Olo luphawu lwecandelo elaqondwayo, hayi nje ukwenziwa.
