Ababoneleli befektri ye-QT400-18 abahambisi nje ngenqanawa-bazisa ukuzithemba kolwakhiwo. Xa i-hydraulic manifold yakho kufuneka ibambe i-350 bar, xa i-winch center shaft yakho inyamezela ukothuka kwemihla ngemihla kwimeko ye-Arctic offshore, okanye xa indlu yempompo ijongene nodaka olurhabaxa kwi-120 ° C, ibakala lentsimbi yentsimbi ayingombhalo osemazantsi. Sisiseko. I-QT400-18 ayisiyo intsimbi engwevu eqhelekileyo. Lulawulo oluluqilima, i-spheroidal graphite microstructure enegunya eliphantsi le-400 MPa kunye nobude be-18%-ibhalansi enqabileyo yamandla, i-ductility, kunye nobuchule bokuba iziseko ezimbalwa zihlala zifikelela kwiisayizi zebhetshi ukusuka kwi-5 ukuya kwiiyunithi ze-500.
Kutheni i-QT400-18 ingaphumeleli-kungekhona kwilebhu, kodwa kumgangatho wevenkile
Siye sabona iindlela ezintathu zokungaphumeleli eziphindaphindiweyo kwihlabathi lokwenyani lwe-QT400-18 izicelo: ukubalwa kwamaqhuqhuva angaphantsi kwe-120/mm², umlinganiselo we-ferrite/pearlite ukhukuliseka ngaphaya kwe-85/15%, kunye ne-warpage eshiyekileyo ebangela uxinzelelo emva kokugqiba i-CNC. Ezi ayingomngcipheko wethiyori. Zibonakala njengokuqhekeka kokudinwa kwangaphambi kwexesha kwizindlu zempompo yepiston, njengokuphuma konyamezelo kwimizimba yevalvu yoxinzelelo, okanye njengokuqhekeka okuncinci komhlaba ngexesha lokudubula. Oyena nobangela? Uninzi lwe-"QT400-18" yoluhlu lwe-intanethi lubhekisela kuphela kwi-chemistry yamagama-hayi eyona nkqubo yokulawula inkqubo. Ukuthotyelwa kokwenyani kufuna ulawulo olungqongqo malunga nexesha lonyango lwe-magnesium, ubushushu bokugonywa, izinga lokupholisa kubumba, kunye nemijikelo yokupholisa uxinzelelo lwasemva kokuphoswa. Kwiziko lethu le-Qingdao, lonke ubushushu be-QT400-18 bufumana uhlalutyo lwe-spectral, ukuqinisekiswa kwe-nodule morphology nge-ASTM E2399, kunye novavanyo lwe-tensile nge-ISO 6892-1-kungekhona nje kwimivalo yovavanyo, kodwa kwiikhuphoni ezimele zisikwe kwelona candelo lishinyeneyo lokusa.
Udibaniso oluthe nkqo lusombulula oko kufihlwa yi-spec sheet
Abathengi abaninzi bafumana imithombo ye-QT400-18 evela kumthengisi omnye kwaye bagqibezele kwenye. Loo handoff idala amabala angaboniyo. Sisebenza ngomatshini yonke inxalenye ye-QT400-18 endlini-kwangoko emva kokunciphisa uxinzelelo, ngaphambi kokuba kuqale ukwehla komgangatho. Iiseli zethu ze-CNC ezine-axis ezintlanu zisike ngokuthe ngqo kwisanti eluhlaza kusetyenziswa izixhobo ze-carbide ezilungiselelwe intsimbi ye-ferritic ductile. Kutheni le nto ibalulekile? Ngenxa yokuba umatshini we-QT400-18 ngaphandle kokubala i-12-15% yeqhekeza legrafu yegrafu ibangela incoko eyakhelwe-ngaphakathi, i-edge chipping, kunye nokukrazula kwe-subsurface encinci. Sihlengahlengisa imilinganiselo yesondlo nge-18% ngaphantsi kuneeparamitha zentsimbi eziqhelekileyo kwaye sisebenzisa imilomo yokuhanjiswa kwesipholisi ebekwe ngaphakathi kwe-12 mm yendawo yokusika. Isiphumo: uburhabaxa bomphezulu i-Ra ≤ 0.8 μm kumphezulu obalulekileyo wokutywina, u-zero uphinda usetyenziselwe ugxininiso lwebhore kwiivalvu ze-hydraulic spool.
Ukulandeleka akungomaphepha-yi-physics
Xa umthengi waseJamani wachaza ukunxitywa okungalindelekanga kwisiseko sempompo ye-QT400-18, silandele umba kungekhona ukuphosa-kodwa kwi-machining coolant concentration yehla ngaphantsi kwe-7.2% ngexesha lokutshintsha kweveki. Ukulandelelwa ngokupheleleyo kuthetha ukudibanisa icandelo ngalinye nenombolo yalo yobushushu bempahla ekrwada, isitampu sexesha lesithando somlilo, ijiko lokuthoba uxinzelelo, ingxelo yokuhlolwa kweCMM, kunye nebhetshi ethile yokupholisa esetyenziswe ngexesha lokugqiba. Sibhala konke oku-kungekhona kwi-Excel, kodwa kwi-ISO 9001-certified MES yethu, kunye neesignesha zedijithali kuzo zonke iindawo zokukhangela. Akukho mizobo “njengoko yakhiwe”. Yonke inkangeleko iqinisekisiwe ngokuchasene ne-callouts ye-GD&T kusetyenziswa i-Zeiss CONTURA G2 CMMs ilinganiswe kwimigangatho ye-NIST. Ukuba umzobo wakho uxela indawo yokunyamezela Ø0.05 mm kwipateni yebhawudi yeflange, ingxelo yethu yenqaku lokuqala ibonisa ukutenxa okwenyani: Ø0.032 mm-ilinganisiwe, iqinisekisiwe, igcinwe.
Iprojekthi yakho ye-QT400-18 iqala phambi komyalelo
Asizicaphuli izicatshulwa. Sisebenzisana nezisombululo zobunjineli. Xa uthumela imodeli ye-CAD yevalve yoxinzelelo oluphezulu, ii-metallurgists zethu zijonga ukuguquguquka kobunzima bodonga kumngcipheko wokuqina.
