Xa iinjineli zicacisa ukuphoswa kwentsimbi engwevu kwimizimba yevalve ye-hydraulic okanye izindlu zempompo, azikhethi nje izinto eziphathekayo-zibheja ngokuzinza kwe-dimensional phantsi koxinzelelo lwe-300-bar, ukuxhathisa ukunxiba emva kwemijikelo yokusebenza eyi-10,000, kunye nokunyamezelwa kwe-zero kwi-micro-shrinkage kwi-flanges ephethe umthwalo. Yiyo loo nto ukhetha okulungileyo umzi-mveliso wentsimbi engwevu ayithethi ngexabiso eliphantsi okanye ixesha elikhawulezayo lokukhokela. Kumalunga nolawulo lwesinyithi, inkqubo yoluleko, kunye nolungelelwaniso lobunjineli-izinto ezintathu esizibonileyo zisilela ngokuphindaphindiweyo xa ukuhanjiswa kuhambela kude nonxweme ngaphandle kolongamelo lobugcisa olufakwe ngaphakathi.
Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Sisebenza ngomatshini kwaye siphosa amacandelo entsimbi engwevu imihla ngemihla-kungekhona njengempahla, kodwa njengezandiso ezisebenzayo zeenkqubo zoxinzelelo oluphezulu. Iqela lethu labasunguli aliyiphathi i-ASTM A48 Class 30B njengebhokisi yokukhangela. Silandelela ukubalwa kwamaqhuqhuva egraphite ngemm², siqinisekisa isiqulatho seperilite ngemetallografi phambi konyango lobushushu, kwaye siqinisekise amandla okuqina kwileyile nganye yokugalela-hayi nje iisampulu zebhetshi. Ngoba? Ngenxa yokuba indlu yesilinda yempompo yepiston ene-12% yepearlite endaweni yama-85–92% iyasilela kwangoko phantsi kwebhayisekile eshushu. Siyibonile. Kwaye sakha inkqubo yethu ukuyithintela.
Yintoni eyahlula i-iron grey casting factory ethembekileyo kumthengisi wentengiselwano kukudityaniswa ngokuthe nkqo-kungekhona nje kwisixhobo, kodwa kwigunya lokwenza izigqibo. Kwiziko lethu eliqinisekisiweyo le-ISO e-Qingdao, injineli efanayo evuma iicerti zemathiriyeli ekrwada iphinda isayine kwiingxelo zokugqibela zeCMM kwii-callouts ze-GD&T njenge-Ø42.5±0.015 mm enokunyamezela isikhundla esingu-0.05 mm ngokunxulumene nedatum A-B-C. Akukho handoffs. Akukho lahleko yoguqulelo phakathi koyilo lokusakha kunye nokuseta oomatshini. Xa umthengi ethumela umzobo we-winch center shaft roller ene-60° helical grooves ephazamisekileyo, iqela lethu liqhuba ukulinganisa okuqiniswayo *phambi* kokuvunywa kwepateni-kunye nomngcipheko wokubekwa kweflegi onokuthi ubangele i-porosity kwindawo ye-gear mesh. Ayisiyiyo "inkxaso". Yabelana ngobunini bokusebenza okusebenzayo.
- Ukulandelelwa kwezinto kuqalisa ezikweni—hayi kwindawo yokuthumela ngenqanawa. Yonke intsimbi engwevu ithwala inombolo yobushushu edityaniswe kuhlalutyo lwembonakalo, iilog zesantya sokupholisa, kunye nokuqina kwemephu kumacandelo abalulekileyo.
- Akukho nkqubo "yesiqhelo" yokubumba isanti. Sisebenzisa i-resin-bonded molds kwizindlu ezincinci zodonga (2.8 mm ubuncinane), isanti eluhlaza kwiziseko ezinkulu (> 120 kg), kunye namazinga okupholisa alawulwayo kwiiflanges ezixinzelelekileyo-aze nakanye.
- Ukucoca akukokucocwa kweposti-yimbuyekezo echanekileyo. Silungisa i-shrinkage eqikelelwayo (i-0.72% ye-HT250), ilungele ukuchithwa kwesikhunta kwiiseti ze-multi-cavity, kunye nomatshini ophethe i-bores emva koxinzelelo-ukunciphisa i-annealing ukubamba ukujikeleza ngaphakathi kwe-0.008 mm.
Abanye abathengi bacinga ukuba intsimbi engwevu “ilula.” Kodwa ukuntsonkotha kufihla kwiinkcukacha: Umthengisi wakho ukusingatha njani ukwahlulwa kwesulfure kwiindawo ezinzima? Ngaba balinganisa umlinganiselo we-ferrite/pearlite-okanye baxele nje ubunzima bukaBrinell? Ngaba banokubamba i-0.02 mm flatness kwindawo yokunyuka kwe-450 × 320 mm ngaphandle kokugaya? Siye saba nabathengi batshintshela kuthi emva kokunikezela okuthathu okungaphumeleliyo kubathengisi abaphumelele ukuhlolwa okubonakalayo-kodwa bahambisa iinxalenye ezine-subsurface graphite flotation eqhekekileyo ngexesha lovavanyo lwe-hydraulic kwibar ye-220. Ukulungiswa kwakungekho ngcono kwe-QC. Yayilulawulo olungqongqo kwiqondo lokushisa lokugalela (1380-1410 ° C), ixesha lokugoba (ngaphakathi kwemizuzwana ye-20 yokucofa), kunye nokuhambelana kokufudumala kwangaphambili. Le ayiyongcaciso kwidatha yedatha. Baqhelisela izingqisho.
Ukusetyenziswa kobuthunywa-izakhelo zempompo zebala leoyile, ii-hydraulic manifolds zecrane eziphathwayo, iivalve zesistim yebhilge yaselwandle-ifektri yakho yokuphosa intsimbi engwevu kufuneka isebenze ekudibaneni kwesinyithi, ijiyometri, kunye nokulayisha kwehlabathi lokwenyani. Oko kuthetha ukuba kuqinisekiswe ukulinganisa ukulinganisa ngokuchasene nemivalo yovavanyo lomzimba * ngokutshisa ngakunye, kusetyenziswa oomatshini bokulinganisa abalungelelanisiweyo-hayi iikhaliphasi-ukuhlola okokugqibela, kunye nokubamba ukulandeleka okugcweleyo ukusuka kwileyidi ukuya kuthunyelo. Kuthetha ukuqonda ukuba i-AMS 5387 cobalt alloy housings yabelana ngezinto ezifanayo zomatshini kunye neeprothokholi zolawulo lwe-thermal njengoogxa bazo bentsimbi engwevu-kuba idimensional drift ichaphazela zombini ngokulinganayo. Kuthetha ukuthi "hayi" kwixesha elinobundlongondlongo xa imodeli yokuqinisa ibonisa umngcipheko-kunye nokubonelela ngenye indlela eqinisekisiweyo endaweni yesithembiso.
Ukuba ufuna iintsimbi ezingwevu ezisinde kwiminyaka eli-15 kwiindawo zamanzi anetyuwa elunxwemeni okanye ugcine ingqibelelo yesitywina emva komjikelo woxinzelelo we-50,000, qala ngokubonakala kwenkqubo-hayi amanani ekhathalogu. Jonga iiprothokholi zohlolo ezibhaliweyo, hayi izatifikethi kuphela. Qinisekisa ukuba "ukuchaneka" kubandakanya ulawulo lwe-microstructure, kungekhona nje ukunyamezela okuqinileyo. Kwaye khumbula: ukuphoswa kwexabiso eliphezulu kakhulu akusiyo enexabiso eliphezulu leyunithi. Yeyona ilibazisa ukugunyazisa, ibangela ukuba kusetyenzwe ngokutsha, okanye ibeke esichengeni ukhuseleko lwenkqubo. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yakha amacandelo entsimbi engwevu apho ukungaphumeleli ayisiyiyo inketho-ngoko ukuthembeka ayisiyonto. Yisiseko.
