Xa iinjineli zichaza a mveliso yentsimbi, abagcini nje uku-odola iinxalenye-bakhetha iqabane eliqondayo imijikelezo yoxinzelelo lwe-thermal, ulawulo lwe-graphite morphology, kunye nendlela i-0.02 mm dimensional drift kwi-cylinder housing can cascade in hydraulic inefficiency. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Ukuqonda oku akuyothiyori. Yakhelwe kulo lonke ubumba lwesanti olugalelwe, konke ukuphoswa kobushushu kuhlolwe, kwaye yonke i-callout ye-GD&T iqinisekisiwe kwi-CMM.
Ukuchaneka Kuqala Phambi Kokugalela
Uninzi lwabathengi bacinga ukuba intsimbi etyhidiweyo iyintsimbi-de ivalve yabo yoxinzelelo ingasebenzi kwi-280 bar. Yinyani? Ayizizo zonke iintsimbi ezingwevu ezidibana ne-ASTM A48 Class 30B. Ayizizo zonke iintsimbi ze-ductile ezibamba i-nodularity ehambelanayo kwisiseko sempompo ye-45-kg. Siye sabona abathengi besala ukuqhutywa kwemveliso emibini egcweleyo ngenxa yokuba iicerts zemathiriyeli ekrwada ziswele uhlalutyo lweladle ezinokulandeleka-kwaye akukho mntu wayibambayo de kube yi-hydrotesting yokugqibela.
Yiyo loo nto wethu mveliso yentsimbi ithatha i-metallurgy njengobunjineli, hayi ukuthenga. Sifumana kuphela i-ISO 9001-eqinisekisiweyo yentsimbi yehagu kunye ne-ferrosilicon kubaboneleli abaphicothiweyo. Ibhetshi nganye ifumana uqinisekiso lwespectrographic *phambi kokuba* inyibilike. Ubume begraphite kunye nokubalwa kwamaqhuqhuva kuqinisekisiwe nge-ASTM E2367 uhlalutyo lwe-microstructure-kungekhona nje ubunzima okanye iingxelo zokuxinwa. Xa umthengi efuna i-ASTM A ye-winch centre shaft roller, siyihambisa nge-log yembali yokushisa epheleleyo, kungekhona nje isitampu sebakala.
Olu qeqesho luhlawula apho lubalulekileyo: kubomi bokudinwa. Izindlu zethu ze-piston pump cylinder zihlala zidlula i-1.2 yezigidi zemijikelezo yoxinzelelo kuvavanyo lomntu wesithathu-kuba inkqubo yokuphosa ilawula izinga lokubanda, igwema i-micro-shrinkage kwiifayili ezibalulekileyo, kwaye iqinisekisa umlinganiselo ofanayo we-pearlite / ferrite kuwo wonke amacandelo eludongeni.
Apho i-Casting idibana ne-CNC-Ngaphandle kokuthobela
Ezinye iifektri zikhupha oomatshini. Abanye baphatha ukuphosa kunye nokugqiba njenge-silos ezahlukeneyo. Oko kudala izikhewu: ii-datum ezingalungelelanisiweyo, uxinzelelo olungalawulwayo lwentsalela, ilahleko yengqibelelo yomphezulu ngexesha lokurhabaxa. Asiyenzi loo nto.
Ukudityaniswa kwethu ngokuthe nkqo kuthetha iqela elifanayo eliyila inkqubo yokungena kwakhona iprogram ye-5-axis mill egqiba isitulo sevalve. Isiphumo? Izindlu ze-Cylinder ezine-± 0.015 mm zithwele ukugxila-eziphunyeziweyo ngaphandle kokunciphisa uxinzelelo lwasemva komatshini. Iziseko zempompo ezinomgangatho oxhonywe ngoomatshini obanjwe ukuya ku-0.005 mm flatness ngaphezu kwe-600 mm-ngelixa kugcinwe ukuqina kolwakhiwo lwe-as-cast kwiindawo ezingezizo oomatshini.
Sisebenza ngomatshini into ebalulekileyo: ukutywina umphezulu, iijenali ezithwele, ubuso beflange. Sishiya oko kusebenzayo: iimbambo, i-gussets, kunye ne-contours ekhupha ukushisa-kanye njengoko yenziwe kwi-Foundry. Akukho kuphinda kusebenze. Akukho ngqikelelo. Ijometri esebenzayo nje, inikezelwe.
Umgangatho Wokungalalanisi—Akukokuthotyelwa Kuphela
"Isiqinisekiso se-ISO" ayiqinisekisi ukuba umlomo wakho we-cobalt alloy uya kusinda kwi-450 ° C kwibhayisekile eshushu. Siyazi-kuba siye savavanya amacandelo e-AMS 5387 phantsi kweemeko zehlabathi lokwenyani: ukuvezwa kwenkungu yetyuwa elandelwa kukothuka okukhawulezileyo kwe-thermal, emva koko uvavanyo lokuhamba komsebenzi kuxinzelelo olulinganisiweyo.
Inkqubo yethu yomgangatho ibethelela isiqinisekiso kwiindawo ezine ezingaxoxisiyo:
- Imathiriyeli engenayo: I-Spectrographic ID + isiqinisekiso sobungakanani beenkozo phambi kokuba kunyibilike
- Njengoko ijiyometri: Iskena esipheleleyo seCMM seempawu ezibalulekileyo-akukho sampuli
- Uzinzo emva kobushushu: Ukujongwa kwakhona kweDimensional emva kokunciphisa uxinzelelo okanye ukuphelisa
- Ukuqinisekiswa okusebenzayo kokugqibela: Uvavanyo loxinzelelo, ukugqiba komphezulu umlinganiselo weRa, uhlolo olubonakalayo ngokwe-ASME B16.1 okanye i-AQL ethe ngqo kumthengi
Inxalenye nganye ithunyelwa nge-traceability matrix: inombolo yobushushu, ilogi enyibilikayo, iirekhodi zokuhlola, kunye nengxelo ye-GD&T. Ukuba icandelo liyasilela ebaleni, silwakha kwakhona uhambo lwalo lonke-hayi nje umsebenzi wokugqibela.
Kutheni iinjineli zehlabathi zikhetha le Factory yentsimbi yeCast
Izixhobo ze-oilfield yaseMntla Melika i-OEMs iodola kuthi ngenxa yokuba siqinisekisa imizobo * phambi * kwezixhobo-ukubamba imiba yokuphazamiseka kwiindawo zempompo ye-cobalt ye-cobalt ye-T800 eya kubiza i-$ 18,000 kwi-castings echithiweyo. Abadibanisi benkqubo ye-hydraulic yaseYurophu baxhomekeke kuthi kwiibhetshi zevalve yoxinzelelo oluphinda-phindayo-apho i-99.2% isivuno sokuphumelela kokuqala "ingalunganga ngokwaneleyo." Isisiseko.
Asithengisi iicastings. Sixazulula iingxaki ngokuzinza kwe-dimensional, ukumelana nokunxiba, kunye nokunyaniseka koxinzelelo-ixhaswa yidatha, kungekhona izithembiso. Xa ufuna i mveliso yentsimbi ethetha ngesinyithi esityibilikayo, i-GD&T, kunye nobunjineli besicelo-hayi nje ukucaphula isoftware-usebenza nabantu ababambe ipateni, bafunde i-micrograph, kwaye babukele i-CMM probe ilandelela indawo yokwenyani yomngxuma wedatum we-3 mm ububanzi.
Ngexesha elizayo xa ukhankanya icandelo lesamente, buza: Ngaba umthengisi wakho ulawula igraphite? Ngaba banokubamba i-0.02 mm kwibhore eyenziwe ngoomatshini *kunye* nesiqinisekiso sobuqhetseba kwindawo yonke eyi-300 mm? Ngaba bavavanya umsebenzi-okanye ukuthotyelwa nje? Loo mahluko wahlula umthengisi a mveliso yentsimbi yakhelwe umsebenzi obalulekileyo wobuthunywa.
