Stellite 21 haingori imwe cobalt-yakavakirwa alloy-ndiyo mainjiniya emidziyo anosvika kana kutadza isiri sarudzo. High-tembiricha ngura, abrasive slurry, cyclic pressure spikes: idzi hadzisi dzemakesi mumapombi ehydraulic kana miviri yevharuvhu yeoiri. Iwo mazuva ese ekushanda mamiriro. Uye munzvimbo idzodzo, Stellite 21 inopa kuyerwa kupfeka kuramba, microstructural kugadzikana, uye galling kuramba uko akajairwa Stainless simbi kana Inconel 625 inodonha.
Asi kutsvaga Stellite 21 hakusi kwekutsvaga * chero * mutengesi. Ndezvekutsvaga a Stellite 21 fekitari iyo inobata metallurgy seinjiniya-kwete logistics. Takaona mapurojekiti akawandisa achinonotswa nekuoma kusingawirirani (HV 380–450 siyana ichidhiraivha mumabhechi), kusagadzikana kwechimiro mushure mekurapwa kwekupisa, kana kupera kwepasi uko kunotadza kushanda chisimbiso zvinodiwa. Iko kukundikana hakuwanzo kubva kune alloy pachayo. Ivo vanobva kumatanho akapatsanurwa: kukanda kunoitwa kumhenderekedzo yegungwa, machining kuendeswa kune zvitoro zvebasa zvakajairika, hapana kuteedzera pakati pebillet certification uye yekupedzisira CMM chirevo.
Nei "Factory Direct" ichichinja Mhedzisiro Yepasirese
KuQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., "fekitari yakananga" inoreva kutonga kwakazara pamusoro pezvikamu zvina zvisinga kurukurwe: yakasimbiswa AMS 5387-inopindirana neraw material kudya, kunyatsoita investimendi kwakaoma geometries senge pombi nozzles uye zvigaro zvevharuvhu, multi-axis CNC kugadzirisa uye kuongorora kwako kwekupedzisira mukunetsekana CNC machining. GD&T callouts-kwete generic kushivirira. Hatitengesi. Isu tinogadzira.
Uku kusanganisa kwakamira kunogadzirisa matatu-akaratidza marwadzo mapoinzi:
- Dimensional kukukurwa mune yakakwira-aspect-ratio zvikamu: Imba yepiston pombi humburumbira yatakagadzira kota yekupedzisira yakabata ± 0.015 mm concentricity kumativi 280 mm kureba-nekuti kukanda shrinkage kwakaenzanisirwa uye kwakabhadharwa pamberi pekugadzira nzira yezvishandiso, isina kururamiswa post-machining.
- Microcrack kuumbwa munzvimbo dzakakanganiswa nekupisa: Yedu T800-alloy plugs yakaitwa annealing pa1180 ° C ± 5 ° C, ichiteverwa nekudzora kutonhora-kwete kudzima kwechoto-yakasimbiswa paASTM E112 saizi yezviyo kuongororwa.
- Surface kuperera kusaenderana: Kana mutengi weEurope aida Ra ≤0.4 µm pachigaro checobalt-alloy kuti ienderane ne elastomer, purogiramu yedu yekupedzisa yaisanganisira vibratory deburring, electrochemical polishing, uye white-light interferometry verification-kwete kungoona kudarika / kukundikana.
Chii "High-Performance Alloy Solutions" Chaizvoizvo Inopa-Kwete Zvivimbiso
Vamwe vatengesi vanonyora Stellite 21 mune yavo catalog uye vanomira ipapo. Tinoitora sehurongwa. Chese chikamu chatinotumira chinotakura humbowo hwakanyorwa: mill test mishumo inoenderana neAMS 5732 kemikari inogumira, kuomarara kwemepu dzinoratidza HV kuenderana pazviso zvakasakara zvakapfekwa, uye kuteedzera kwakazara kwakawanda kubva kunhamba yekupisa kusvika kune yekupedzisira kurongedza label. Hapana kunze - kunyangwe kune prototypes.
Isu tinoziva zvakare izvo Stellite 21 *haisi * kugadzirisa. Izvo hazvigadzirise hurombo hwe hydraulic dhizaini. Izvo hazvizobhadhara shafts isina kurongeka kana isina kuenzana rotors. Saka ongororo yedu yeinjiniya inotanga nekukasira: isu tinomira GD&T kusawirirana tisati tacheka simbi, tinopa zano kugadziridzwa kweradii kuderedza kusagadzikana mumashandisirwo epamusoro-soro, uye kusimbisa kana mhinduro yecobalt-nickel ichidiwa zvechokwadi-kana kana yakaomeswa 17-4PH ine nitriding yakagadziridzwa yaizounza hupenyu hwesevhisi hwakaenzana nemutengo wakaderera.
Chirango ichocho chinoratidza mukutumirwa chaiko. Imwe yeNorth American oilfield yemidziyo OEM yakatsiva yakagadzirwa 4140 valves stems neshanduro yedu yeStellite 21-clad. Nguva yepakati pakati pekutadza yakasvetuka kubva pa42,000 kusvika ku117,000 maawa ekushanda. Kwete nekuti iyo alloy ndeyemashiripiti - asi nekuti iyo yese chain chain - kubva kujecha mold dhizaini kusvika yekupedzisira ultrasonic bvunzo - yakagadzirwa kutenderedza kushanda kwekuita, kwete kungotevedzera zvinhu.
Maitiro eKusimbisa Yechokwadi Stellite Fekitori-Kupfuura Webhusaiti
Bvunza mibvunzo iyi mitatu usati waita:
- Unogona here kupa chitupa chebatch chazvino chinoratidza kabhoni yemukati ≤0.25%, chromium ≥27.5%, uye tungsten ≥13.5% - zvese zvakasimbiswa neOES spectroscopy, kwete mill mishumo chete?
- Iwe unoita post-machining residual stress chiyero pane zvikamu zvinopfuura 150 mm mune chero chiyero-uye gadzirisa kupisa kurapwa zvinoenderana?
- Yako ISO 9001:2015 scope yakanyorwa zvakajeka kuti ibatanidze "kukandira uye machining ecobalt-chromium alloys," kana ndeye "generic zvesimbi zvikamu"?
Kana mhinduro dzisina kujeka, dzakanonoka, kana kuti dzinoda kutumirwa kwechitatu-uri kutaura nemugovera, kwete Stellite 21 fekitari. PaQINGDAO QIANGSENYUAN, magwaro iwayo anogadzirwa mumba, anoongororwa nevemetallurgists, uye anogovaniswa mukati memaawa makumi mana nemasere ekukumbira.
Kuita kweStellite 21 hakusi dzidziso. Inoyerwa mumaawa ekushanda kusingakanganiswe, mamicrons ekurasikirwa kwekupfeka pamiriyoni imwe neimwe, uye zero yemunda inodzoka pamishoni-yakakosha pombi magungano. Kuvimbika ikoko kunotanga kwete neiyo alloy database-asi neanodzora choto, chirongwa cheCNC, uye yekupedzisira yekuongorora protocol. Kune mainjiniya anotsanangura zvikamu uko nguva yekudzikira inodhura $12,000/awa, musiyano iwoyo hauna ruzivo. Ndiwo mutsauko uripo pakati pechokwadi chechirongwa uye kuronga kwenjodzi.
