Iyo pompe ya hydraulic yananiwe mu ruganda rwa peteroli rwo hanze - cyangwa uruziga rufata imbere mu bucukuzi bw'amabuye y'agaciro - intandaro ni gake. Ni kwambara. Kandi ntabwo kwambara gusa: micro-abrasion, galling, umunaniro wumuriro munsi ya 300 ° C imitwaro ya cycle. Aho niho Icyogajuru ibice 6 uruganda ubushobozi bureka guhitamo. Ihinduka itandukaniro riri hagati yamasaha 8000 yumurimo no gutsindwa kwa catastrophique.
Twashyize Stellite 6 nozzles kuri sisitemu yo gutera aside irike cyane muri Arabiya Sawudite-kandi twarebye ko irenga ibisekuruza bitatu byabasimbuye bisanzwe. Twakoze imashini ya AMS 5387 ya piston pompe yububiko bwa OEMs yo mu Budage yasabye kuzenguruka mm 0.015 mm kuri diametero 200 mm, hamwe no kurangiza Ra ≤0.4 µm nyuma yo gusya bwa nyuma. Ibi ntabwo aribisobanuro byihariye. Nibipimo bya buri munsi mubigo byacu byemewe na ISO byemewe na mashini i Qingdao.
Icyogajuru cya 6 ntabwo ari "ubundi buryo bwa cobalt." Ibigize - hafi 65% Co, 28% Cr, 4% W, wongeyeho Ni, Fe, na C - ikora matrix ya karbide ikomeye ya chromium yashyizwe mubisubizo bikomeye bya cobalt. Ibyo biha imbaraga zidasanzwe zo kurwanya ibyuma-byuma, kwangirika mubidukikije bikungahaye kuri chloride, no koroshya ubushyuhe bugera kuri 500 ° C. Ariko dore ibyo abaguzi benshi birengagiza: guta Stellite 6 ntabwo ari nko guta ibyuma. Ahantu ho gushonga cyane (1,290–1,350 ° C), amazi make, no kugabanuka gukabije bisaba amarembo yihariye, kugenzura neza ubushyuhe bwambere, hamwe no kuvura ubushyuhe bwa homogenisation. Simbuka intambwe iyo ari yo yose - hanyuma ubone gutinyuka, gutandukanya karbide, cyangwa gucamo ibice interdendritic. Twabonye abakiriya banze 40% byabakinnyi ba mbere batanze ibyangombwa. Umusaruro wacu kuri Stellite 6 igoye gushora imari kuri 92% + kuko tugenzura buri gihindagurika: ibyemezo byibikoresho fatizo (ibyiciro byose bya T800 yo mu rwego rwa cobalt base alloys bikurikiranwa na raporo y'ibizamini by'urusyo), isoko ya vacuum yashonze, hamwe nigihe cyo gushushanya ubushyuhe mugihe gikwiye.
Kwishyira hamwe guhagaritse gutandukanya inganda zizewe 6 ibice nabacuruzi. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. Iyo umukiriya yohereje igishushanyo kumashanyarazi adasanzwe asanzwe ya cobalt hamwe numuyoboro wo gukonjesha wa asimmetrike hamwe na 0.008 mm kwihanganira imyanya kubintu bitanu bifatanye, ntabwo dusohora impinduka. Turayikoresha kuri 5-axis DMG MORI NTX 1000, dukoresheje ibikoresho bya PCD byerekanwe neza kuri cobalt alloys, hamwe na laser yo kugenzura kugirango igenzure ubugari bwurukuta mbere yo gusya indangamuntu ya nyuma. Nta mucuruzi wo hanze wumva uburyo guhangayika gusigaye guterwa bigira ingaruka kumashini igoreka kuri mm 320 z'uburebure bwa valve. Turabikora - kubera ko tuyijugunye, kuyitwara ubushyuhe, kuyikora, no kuyigenzura hamwe na gahunda imwe ya CMM kuva itangira kugeza irangiye.
Imikorere nyayo yisi ishingiye kubintu bitatu bidashobora kuganirwaho-ntabwo bisaba ibicuruzwa. Icya mbere: guhuza ibintu. Buri gice cya Stellite 6 gikorerwa isesengura rya spekrographie, gushushanya amakarita yambukiranya ibice, hamwe no kugenzura ingano ya ASTM E112. Icya kabiri: ubudahemuka. Twemeza ubuso bukomeye dukoresheje profilometero optique - ntabwo ari CMM gusa - kugirango dufate micro-topografiya igira ingaruka ku busugire bwa kashe. Icya gatatu: Kwemeza imikorere. Mbere yo koherezwa, buri cyuma cyumuvuduko gikorerwa hydrostatike kuri 1.5 × umuvuduko wakazi; buri nzu ya pompe ibona igenzurwa na helium mass spectrometry. Abakiriya bo muri Amerika ya Ruguru hamwe n’Uburayi ntibasaba ibyemezo-basaba raporo y'ibizamini byihariye byakozwe na timestamp, indangamuntu, hamwe na kashe ya kalibibasi. Turabatanga.
Niba gusaba kwawe kurimo gusebanya, ubushyuhe bwo hejuru, cyangwa cycle yikuramo hejuru ya MPa 200, Stellite 6 ntabwo irenze injeniyeri. Ni ubwishingizi. Ariko ubwishingizi bukora gusa mugihe uwabitanze yerekanye uburambe-ntabwo ari udutabo gusa. Shakisha intsinzi yanditse mumirenge yawe: guteranya pompe kubisabwa munsi yinyanja, winch center shaft rollers ya crane ikora cyane, cyangwa cobalt alloy nozzles kubihingwa byangiza. Reba niba bafite ibyemezo bya AMS 5387 - ntabwo ari ibikoresho gusa. Kugenzura niba inyandiko zabo zifite ireme zirimo gukurikiranwa kugeza kumubare wubushyuhe bwa cobalt ingot. Noneho gereranya disipuline yo gutanga: barashobora gufata windows yiminsi 3 kumadirishya yo hagati batagabanije amafaranga? Ngiyo umukono wukuri Icyogajuru ibice 6 uruganda—Ntabwo iduka ryakazi rifite cobalt alloy datasheet.
