Xa usiva 'inxalenye yevalve ye-homogenizing', uninzi lucinga ngeqhekeza elilula, elinokutshintshwa kwideri okanye kumgca wokulungisa ukutya. Leyo yimbono yokuqala ephosakeleyo. Ngokwenyani, licandelo lokunxiba elichanekileyo elichaza ukusebenza kakuhle kunye nokuhambelana kwemveliso ye-homogenizer yoxinzelelo oluphezulu. Indawo yokungaphumeleli ayidlanga ukuba ngumzimba wevalve, kodwa indawo ethile yokunxibelelana-isihlalo kunye nentloko yevalve, ehlala yenziwe kwiialloys ezikhethekileyo. Ndibone imisebenzi emininzi kakhulu iyiphatha njenge generic spare, iodola olona khetho lubiza imali eninzi, kuphela ukujongana nemiba yokuhanjiswa kobungakanani bamasuntswana kunye nexesha lokuphumla emva kweeveki. Ukusebenza kwenxalenye yinto yonke.
INdawo nguMyalezo
Awukwazi ukuthetha ngezi valve ngaphandle kokungena nzulu kwi-metallurgy. Umgangatho we-316L we-stainless usebenzela usetyenziso olungabhubhisiyo, kodwa liqhezu elincinci elo. Nayo nayiphi na into enefiber, iiminerali, okanye izinto eziqinileyo eziphezulu, ukwindawo ye-stellite (cobalt-chromium alloys) okanye itungsten carbide. Ukhetho apha alukho ithiyori. Ndikhumbula iprojekthi yomvelisi webhotolo yeendongomane. Babevutha ngezihlalo ezingama-316L rhoqo kwiiyure ezingama-150. Sitshintshele kwi-alloy esekwe kwi-cobalt ukusuka kwisiseko esinobuchwephesha besayensi yezinto ezinzulu, njengaye Qingdao Qiangsenyuan Technology Co., Ltd.(QSY). Ujoliso lwabo lweminyaka engama-30 utyalo mali kuba i-alloys ezikhethekileyo zithetha ukuba baqonda ukwakheka kweenkozo ezifunekayo ukuxhathisa impembelelo, kungekhona nje ubunzima. Inxalenye yobomi yatsibela ngaphezulu kweeyure ezingama-1200. Yayingengomlingo; yayilawulwa ukuqina kunye nonyango lobushushu emva kokuphoswa.
I-nuance ikwinkcukacha. Ukucela nje istellite akwanelanga. Ngaba yi-Stellite 6, 12, okanye i-21? Ngamnye unematrix eyahlukileyo. Ukuze ufumane i-abrasion egqithisileyo, unokufuna umaleko we-ceramic-metal composite. Ndiye ndanokusilela apho izinto bezichanekile ngokobuchwephesha, kodwa indlela yokuphosa yazisa i-micro-porosity. Ngaphantsi kwe-250 bar yoxinzelelo, ezo voids ezincinci ziba ziindawo zokuqalisa ukwaphuka. Yiyo loo nto ulawulo lwenkqubo ye-Foundry-inkqubo yabo yokubumba iqokobhe, iqondo lobushushu lokugalela, kunye nesantya sokupholisa-ibaluleke kakhulu njengefomula yealloyi. Ivenkile eyenza ngokubanzi CNC Machining inokwenza inxalenye ekhangeleka kakuhle, kodwa ukuba i-substrate ineziphene, iya kusilela.
Oku kukhokelela kumgibe oqhelekileyo: ubunjineli obugqithisileyo. Kukho intsingiselo yokuchaza eyona nto inzima, eyona imathiriyeli yangaphandle kwisicelo ngasinye. Yinkcitho. Isihlalo se-tungsten carbide esidityaniswe nentloko yevalve ye-carbide sinokuba brittle kakhulu kwimithwalo ethile eshukumisayo, ekhokelela ekuqhekekeni. Ngamanye amaxesha, i-alloy eyomeleleyo, ethambileyo kancinane enxiba ngokufanayo ingcono kune-ultra-hard leyo esilela ngentlekele. Umnxeba womgwebo uvela ekwazini i-rheology yemveliso. Ngaba kukucheba? I-Abrasive? Oko kuyalela isibini sezinto eziphathekayo.
Ukuchaneka kukwiJiyometri kunye noGqiba
Umsebenzi wevalve-ukunyanzeliswa kwemveliso ngokusebenzisa i-gap ye-micron-scale-ithetha ukuba ijometri ayinakuxoxisana. Ukuthe tyaba komphezulu wokutywina kwesihlalo, i-engile yentloko yevalvu, kunye nokukhutshwa kweradial kulinganiswa ngeemicrons. Ndiye ndahlola iindawo ezibonakala zigqibelele kodwa zabangela ukuba i-homogenization ingahambelani ngenxa yokuba indawo enesihlalo esilaphukileyo yayinokutenxa nje kwee-microns ezimbini, idala indlela yokuhamba engalinganiyo. Ukugqitywa, okuhlala kuyinkqubo yokuqengqeleka yamanyathelo amaninzi, kulapho ubugcisa budibana khona nesayensi.
Apha kulapho umthengisi umatshini Ikhono libonisa. Yinto enye ukuphosa inxalenye ye-net-shape ekufutshane intsimbi engenasici okanye i-cobalt alloy. Ngomnye ukubamba ukunyamezela kwe-0.001 kwiprofayili yangaphakathi eyinkimbinkimbi emva konyango lobushushu, elinokuthi lidibanise iqhekeza. Inkampani efana ne-QSY, edibanisa ukuphosa kunye ne-CNC phantsi kophahla olunye, inenzuzo. Banokuyila ukuphosa ukunciphisa uxinzelelo lomatshini kwaye babe nomthamo we-CNC wokuwugqiba ukucacisa. Ndikhe ndajongana namatyathanga obonelelo ahlukeneyo-i-foundry ithumela kwivenkile yomatshini-kwaye uxanduva luyalahleka. Ngaba intanda yavela ekujuleni okanye yayiluphawu lwesixhobo sokungqusha? Umenzi odibeneyo unokulandelela oko.
Umphezulu wokugqiba (ixabiso likaRa) ubalulekile kodwa kaninzi awuhoywa kwimizobo. Kakhulu, kwaye ufumana amanqaku e-nucleation yokhukuliseko kunye ne-bhaktiriya harborage. Igudiswe kakhulu (ukugqiba kwesipili), kwaye usenokungaphumeleli itywina eliyimfuneko ngaphandle kwamandla agqithisileyo. Kwizicelo zamachiza, inkqubo yokupasa emva komatshini yenye ingqimba. Zezi nkcukacha ezahlula inxalenye esebenza kwenye esebenza ngokugqibeleleyo iminyaka.
Ukungaphumeleli kokwenyani kwehlabathi kunye nokuphindaphinda
Ufunda ngakumbi kwinxalenye engaphumeleliyo kuneleyo egqibeleleyo. Kwasekuqaleni komsebenzi wam kunye nomxhasi we-bio-fermentation, sachaza i-alloy ye-nickel ephezulu ye-valve ye-homogenizing ephethe i-lysate yeseli. Ukumelana nomhlwa kwakugqibelele, kodwa i-alloy yasebenza nzima kakhulu ngexesha lokusebenza. Emva kwemijikelo embalwa, umphetho wentloko yevalvu waba lukhuni kangangokuba waba brittle kwaye micro-spalled, engcolisa imveliso. Isifundo esinexabiso elikhulu. Siye safudukela kwibakala elahlukileyo le-nickel-based alloy grade kunye nokuzinza okungcono, okwakufuna ukusebenza ngokusondeleyo kunye ne-Foundry ukulungisa isisombululo se-annealing parameters.
Elinye ityala libandakanya i-valve cavitation. Umthengi wayebona imingxuma engaqhelekanga kwicala lokungena lesihlalo, hayi ubuso obunxibileyo. Impahla kunye nokugqiba kwakumele kucaciswe. Umba walandelwa umva kwimpompo ephezulu edala i-oscillations yoxinzelelo, ebangela ukuba amaqamza e-cavitation aqhume ngokuchasene nenxalenye. Ukulungiswa kwakungeyona ivalve engcono, kodwa i-damper kumgca. Nangona kunjalo, siye sawandisa amandla esivuno semathiriyeli kwibhetshi elandelayo ukuze imelane ngcono namandla e-implosion. Yingxaki yeenkqubo, kodwa inxalenye yevalvu ithatha umonakalo.
La mava agxininisa ukuba inxalenye yevalve ye-homogenizing yinkqubo yojongano. Ukusebenza kwayo kubotshelelwe kwi-homogenizer's plunger wear, ukuzinza koxinzelelo lwesondlo, kunye nobushushu bemveliso. Awunakuvele uyitshintshe ibe yedwa. Olona qheliselo lungcono kukubhala iiyure zokusebenza, jonga ipateni yokunxitywa kwinguqu nganye, kwaye ukondla oko kubuyela kumenzi wenxalenye. Ipatheni yokunxiba okungalinganiyo ingabonisa ukungahambi kakuhle kwibhloko ye-homogenizer, ingeyiyo inxalenye yesiphene.
Ukufumana kunye neXabiso leeSpecialized Foundries
Oku kundizisa ekufuneni. Imakethi izele ziikopi ezishibhileyo, ezihlala ziguqulwa ngobunjineli kwiisampulu ezigugileyo. Ziyalingana, kodwa azenzi. Ukuchaneka kwedimensional kunokupheliswa ngabambalwa, okanye unyango lobushushu luyatsitywa ukonga iindleko. Imowudi yokungaphumeleli ikhawuleza, inxibe ukungalingani kunye nokunyuka kokusetyenziswa kwamandla njengoko i-homogenizer isebenza nzima ukufezekisa uxinzelelo. Ixabiso lilonke lenxalenye engaphumeleliyo-ixesha lokuphumla, ilahleko yemveliso, inkcitho yamandla-yincinci iprimiyamu yexabiso lecandelo elenziwe ngokufanelekileyo.
Yiyo loo nto intsebenziswano kunye nesiseko esikhethekileyo sobugcisa kubalulekile. Inkampani efana QSY (ungafumana amandla abo apha https://www.tsingtaocnc.com) imele inqanaba elithile. Ukusebenza kwabo ixesha elide kwi iqokobhe ngundo kwaye utyalo mali, ngokukodwa ukubiza amava nge-cobalt kunye ne-nickel alloys, iimpawu eziqondayo i-niche. Kwinxalenye yevalvu ye-homogenizing, inkqubo yabo kusenokwenzeka ukuba ibandakanya ukubumba iqokobhe leceramic ukuze kugqitywe umphezulu ongaphezulu kunye nozinzo olunomda kwisithuba esingenanto, esisiqingatha sedabi eliphumeleleyo phambi kokuba kuqale ukusebenza.
Ubudlelwane bubalulekile. Ndibathumelele isitulo sevalvu engaphumeleliyo kunye nepateni ethile yokunxiba. Iinjineli zabo zinokuxubusha ukuba ngaba utshintsho kwipesenti ye-carbide kwi-alloy okanye ukulungiswa okuncinci kwi-angle yokutywinwa kwiprogram ye-CNC kuya kunciphisa. Ayingobathathi-odolo nje; bangabasombululi beengxaki kuba balawula inkqubo ukusuka kunyibilika ukuya kumatshini. Le ntsebenziswano yindlela ovelisa ngayo inxalenye yoyilo lwesicelo esithile, usuka kwinto eqhelekileyo yekhathalogu ukuya kwisisombululo esilungiselelweyo, esilungisiweyo.
Iingcinga zokugqibela: Yinxalenye yokunxiba, yiphathe njengenye
Ke, ukusonga oku, inxalenye yevalve ye-homogenizing iyinto etyiwayo, kodwa ixabiso eliphezulu, elichanekileyo elinokusebenziseka. Into ephambili kukuyicacisa ngononophelo olukhulu njengoko i-homogenizer ngokwayo. Qala ngokuqonda ngokunzulu umjelo wemveliso yakho. Emva koko, iqabane kunye nomvelisi onesiseko sesayensi yezinto kunye nomatshini odibeneyo wokuphumeza. Musa ukuthumela nje umzobo; thumela umxholo-uxinzelelo lokusebenza, imveliso ye-PH, i-abrasives, kunye nobomi benkonzo ekujoliswe kuyo.
Isicwangciso se-Inventory yinxalenye yalo nayo. Ngenxa yamaxesha amade okukhokelela kwii-alloys ezikhethekileyo kunye nomatshini ochanekileyo, awukwazi ukulinda ukusilela ukuodola. Cwangcisa izixhobo zakho ngokusekwe kumaxabiso embali yokunxiba. Kwaye ekugqibeleni, soloko uqhuba i-post-mortem kwindawo etshintshileyo. Ipatheni yokunxiba ixelela ibali malunga nenkqubo yakho yonke ye-homogenization. Ivalve yicanary kumgodi wamalahle. Ukungayinaki imeko yayo okanye ukuyiphatha njengempahla yorhwebo yeyona ndlela ikhawulezayo yokuthomalalisa umgangatho wemveliso kunye nokutshisa imali ngexesha lexesha likaxakeka. Licandelo elincinane elithwala umthwalo omkhulu kakhulu.
