Umzi-mveliso weStellite bushing

Xa iinjineli zichaza a Umzi-mveliso weStellite bushing, abagcini nje ngokuyalela inxalenye-baqinisekisa ukuqhubeka nokusebenza phantsi koxinzelelo olunzima, ubushushu, kunye nokulimala. Siye sabona iindibano zempompo ye-hydraulic zisilela kwi-3,000 psi ngenxa yokuba i-bushing's microstructure ayinayo i-uniform cobalt carbide dispersion. Sibukele izikhondo zevalve engaselunxwemeni zibanjwa emva kweenyanga ezili-18-kungekhona ekudlekeni, kodwa ukusuka kubunzima obungaguqukiyo bobunzima kwiStellite 6. Ezi ayingomngcipheko wethiyori. Ziindlela zokungaphumeleli eziqinisekisiweyo ebaleni ezahlula ababoneleli bempahla kumaqabane achanekileyo.

Kutheni iMaterial Mastery ibaluleke ngaphezu kokusebenza wedwa

I-Stellite bushings ayiphumeleli kwi-lathe. Bayasilela kwi-interface ye-metallurgical. Ukunyamezela kwe-0.05 mm akuthethi nto ukuba i-substrate-to-alloy bond ayinayo ingqibelelo ye-diffusion-okanye ukuba iindawo ezithintekayo ukushisa zinciphisa ukuzinza kwe-carbide ngexesha le-post-weld machining. EQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., yonke icandelo leStellite liqala nge-AMS 5387-certified T800 alloy ingots, enokulandeleka ukuba inyibilike ibhetshi kunye neengxelo zovavanyo oluqinileyo. Asazi "umthombo" wezinto ze-cobalt-nickel-sisebenzisana nokuphuhlisa imijikelo yonyango lobushushu kunye namaqabane ethu e-Foundry ukubamba i-Rockwell C 42-48 * ngokusebenzisa i-cross-section epheleleyo *, kungekhona nje phezulu. Yingakho i-piston pump cylinder bushings yethu ihlala idlula iiyure ze-12,000 kwinkonzo ye-oyile ye-silt ephezulu: ubulukhuni abulinganiswanga ngexesha elinye-buqinisekiswa kubunzulu obuthathu be-radial usebenzisa uvavanyo lwe-micro-Vickers.

Ukudityaniswa okuthe nkqo kuSombulula iiNdawo zeNzululwazi zoMveliso wangempela

Uninzi lwabathengi bajongana ne-bottleneck efihliweyo: ukuphosa i-shrinkage kuphazamisa i-geometry ngaphambi kokuba umatshini uqalise. I-Sand-cast Stellite bushings idla ngokufuna i-+0.3 mm isibonelelo sesitokhwe-emva koko ilahlekelwe ngu-0.15 mm ekuphazamisekeni koxinzelelo. Siyayiphelisa loo mpazamo. Indawo yethu ehambelana ne-ISO iphatha utyalo mali *kunye* ne-5-axis CNC yokusila kwindawo enye elawulwayo. Siphosa i-rough blank kunye ne-0.08 mm ukunyamezela komlinganiselo kwii-ID ezibaluleke kakhulu, emva koko sigqibezele indawo yokutywina kwaye sicinezele i-OD kwi-setup enye-akukho ukulungiswa kwakhona, akukho lag ye-thermal phakathi kweenkqubo. Kwiirola ze-winch yemoto yeziko lobunjineli, oku kucutha ixesha elipheleleyo lokukhokela ngama-37% xa kuthelekiswa nokuthengiswa okulandelelanayo. Abathengi basixelela eyona mpumelelo inkulu ayisosantya-kukuqikelelwa. Akusayi kuphinda kurhoxiswe ngomzuzu wokugqibela i-GD&T kuba i-ID yokuphosa ikhutshiwe ngaphandle kwenkcazo.

Ulawulo Lomgangatho Obonisa Uxinzelelo Lwesicelo sakho

Sihlola i-Stellite bushings ngokungathi ziya kuqhuba isitakhi sakho se-subsea BOP-hayi ngathi ziya kuhlala eshelufini. Yonke iqashiso lenziwa uvavanyo lwe-ultrasonic lwe-subsurface porosity, ilandelwa kukuhlolwa kwedayi kuyo yonke imiphezulu yokukhwelana. Kodwa umahluko wokwenyani kukuqinisekisa okusebenzayo: sivavanya i-bushings egqityiweyo ukuya kwi-1.5 × inqanaba loxinzelelo lwenkqubo ngelixa uzijikelezisa kwi-120 RPM ngokuchasene neejenali zentsimbi eqinile. Ukuba ukuvuza kudlula i-0.3 cc/min okanye i-torque spikes>8%, inxalenye iyasilela-nokuba idlula yonke i-dimensional check. Oku kuphinda-phinda iimeko zokuqalisa impompo zokwenyani apho ukwandiswa kwe-thermal ukungahambelani kubangela inyonyo okomzuzwana. Sibhala yonke ijika yovavanyo, hayi nje ukupasa/asiphumeleli. Ufumana idatha ekrwada-kungekhona nje isitampu.

Ukuchaneka ngokweSiko akusiyo iXesha leNtengiso-YiBhili yakho yeMpahla

I-"custom" ye-Stellite bushing inikezela ngexabiso kuphela ukuba isombulula imowudi yakho yokusilela. Sakhe iijiyometri ezingekho mgangathweni kubathengi abafuna:

• Ubukhulu bodonga lwe-asymmetric ukubuyisela ukulayisha okungalinganiyo kwe-thermal kwiinkqubo ze-lube ye-turbine enesantya esiphezulu.
• Iigrooves ezidityanisiweyo zokupholisa zenziwe ngoomatshini ngokuthe ngqo kwi-Stellite layer-ngaphandle kokuyekelela ukuqhubeka kwe-carbide
• Ujongano lweHybrid: Umkhono weStellite 6 wangaphandle odityaniswe kwi-17-4PH engundoqo wangaphakathi wokumelana nokudinwa + ukuhambelana kokuhlolwa kwesuntswana
