sera yabwino kwa fakitale yotaya sera

Kusankha a sera yabwino kwa fakitale yotaya sera ntchito sizokhudza kupeza njira yotsika mtengo kwambiri - ndi kuchotsa zolephera zobisika zisanafike kung'anjo. Tawonapo zinthu zambiri zopanga zinthu zikuyimitsidwa pakutha chifukwa cha zotsalira za sera zomwe zikutsekereza ndime zabwino zapampu ya cobalt alloy. Ena ataya 30% ya batch pambuyo posweka chipolopolo-kubwerera kukukula kosasinthasintha kwa kutentha panthawi yotulutsa phula. Izi sizowopsa zongoyerekeza. Ndiwo mtengo watsiku ndi tsiku mu nthawi, zinthu, komanso kudalirika kwamakasitomala.

Chifukwa Chake Ma Wax Okhazikika Amalephera Pakufunidwa Kwa mafakitale

Mafakitole ambiri amayamba ndi ma wax opangira ndalama wamba omwe amapangidwira zodzikongoletsera kapena zotayira zotsika kwambiri za aluminiyamu. Izi zimagwira ntchito-mpaka mutayendetsa matupi a AMS 5387 cobalt alloy valve pa 1,550 ° C kapena ma nozzles a T800 omwe amafunikira ± 0.05 mm dimensional control pazigawo za khoma la 0.8 mm. Sera zokhazikika zilibe zinthu zitatu zomwe sizingagwirizane: kutenthedwa bwino popanda phulusa pansi pa 650 ° C, ziro tack pambuyo pa kugwetsedwa, ndi kuchepa kwa kutentha pansi pa 0.45% kuchoka pa 25 ° C mpaka 60 ° C. Popanda iwo, mumapeza ma depositi a kaboni omwe amawononga kutha kwa pamwamba, kukokera kwa nkhungu komwe kumasokoneza ma flanges opyapyala, kapena ming'alu yaying'ono mu zipolopolo za ceramic panthawi ya nthunzi.

Tinayesa ma wax asanu ndi awiri a mafakitale m'miyezi 18 - kuphatikiza mitundu iwiri ya eni ake - pazigawo zenizeni zopangira: nyumba za silinda pampu ya piston, ma hydraulic pressure valves, ndi ma winch center shaft rollers. Atatu okha ndi omwe adadutsa kutsimikizira kwathunthu. Wopambana kwambiri sanali sera wosungunuka kwambiri. Ndilo lomwe linali lolimba kwambiri (52-54 ° C), kukhuthala kotsika kwambiri pa 65 ° C (8,200 cP), ndi zotsalira za phulusa zovomerezeka pansi pa 0.003% pambuyo pa 620 ° C / 2-ola kupsya pa ASTM F2897.

Njira Zinayi Zaukadaulo Palibe Fakitale Iyenera Kudumpha

Iwalani zonena zamalonda. Izi ndi zomwe zimafunikira pakuyenerera sera pakupanga ndalama zachilungamo:

• Dimensional kukhazikika pambuyo kubayidwa: Sera imayenera kupirira kupirira kwa GD&T pozizira—ngakhale pazigawo zosafanana monga maziko a pampu okhala ndi kutalika kwa 220 mm ndi makulidwe a khoma 3.2 mm. Timayesa shrinkage pamfundo zitatu: pachimake, pakati pa khoma, ndi m'mphepete mwa flange. Kupatuka kovomerezeka: ≤0.38% kusintha kwa mzere wonse.
• Kugwirizana kwa Dewaxing: Kuwotcha kwa nthunzi kumafuna kusungunuka mwachangu, kwathunthu popanda kutupa kapena matuza. Sera yokhala ndi mafuta okwana 0.8% imatulutsa thovu pansi pa nthunzi yodzaza ndi madzi, zomwe zimapangitsa kuti chipolopolo chiwonongeke. Kudutsa kotsimikizika: palibe zotsalira zowonekera mumayendedwe ozizirira amkati a 3 mm pambuyo pa mphindi 12 pa 160 ° C kuzungulira kwa nthunzi.
• Shell adhesion control: Kumatira kwambiri kumayambitsa kusweka kwa zipolopolo panthawi yogwira. Kuchepa kwambiri kumayambitsa kuchotsedwa kwa matope. Mphamvu yabwino ya sera pamwamba: 34–36 mN/m pa 30°C—yoyezedwa pogwiritsa ntchito angle angle goniometry, osati zongoyerekeza.
• Reusability malire: Sera yobwezerezedwanso imatsika mwachangu kwambiri m'tigawo tosakhazikika. Timatsata kutsika kwa point point ndi kuchuluka kwa asidi. Kugwiritsanso ntchito malire: mizere yopitilira 3 ngati nambala ya asidi itsalira <0.8 mg KOH/g ndi flash point imakhalabe ≥110°C.

Momwe QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. Imatsimikizira Kuchita kwa Sera

Pamalo athu ogwirizana ndi ISO ku Qingdao, kuyeneretsedwa kwa sera si ntchito ya labu-ndi chipata chopangira. Sera yatsopano iliyonse imayesedwa nthawi zinayi:

1. Mayesero a magawo 50 a gawo lenileni la kasitomala: AMS 5387 cobalt alloy plug yokhala ndi 0.5 mm radial tolerance pa 12 mm OD.
2. Muyeso wa CMM usanachitike komanso pambuyo pa dewaxing kuti muyese kupotoza kwapatani.
3. Kusanthula kwa Thermogravimetric (TGA) kwa zotsalira zakupsa pazitsulo zosapanga dzimbiri - zotsimikiziridwa motsutsana ndi mapu oyambira a SEM-EDS.
4. Kukalamba kofulumira: maola 72 pa 40 ° C / 85% RH, kutsatiridwa ndi kulimba kwamphamvu ndi kuyesa kwa elongation pa ASTM D638.

Izi zidagwira sera imodzi yomwe idakumana ndi mapepala onse - koma idalephera kuyesa #2. Kukula kwake kwa kutentha kunakwera pamwamba pa 85 ° C, kuchititsa kuti 0.12 mm iwonongeke pamapewa osindikizira ovuta. Mbali imeneyo ikanatha kuyang’anizana ndi maso koma inawukhira pa bar 350 muutumiki wakumunda. Sititumiza zongoganizira. Timatumiza deta.

Kusankha Sera Yanu: Zochita Zotsatira

Musadalire zitsanzo za ogulitsa okha. Yendetsani mndandandawu musanamalize yanu sera yabwino kwa fakitale yotaya sera kusankha:

• Funsani ma curve athunthu a TGA - osati kungonena "zopanda phulusa". Fufuzani kulemera kwa zotsalira pa 550°C, 600°C, ndi 650°C.
• Yesani kufewetsa mawakisi pamakina anu enieni: zomangira zomwezo, stucco yemweyo, nthawi yowumitsa yofanana. Sera yabwino ku zipolopolo za silika ikhoza kulephera kwambiri ndi colloidal zircon.
• Tsimikizirani magawo a jakisoni pamakina anu: kutentha kwa nozzle, liwiro lodzaza, kuthamanga kwa paketi. Kusintha kwa kutentha kwa 2°C kungathe kusintha kukhwimitsa kwa pamwamba pa Ra ndi 0.4 µm—zokwanira kusokoneza kunyowetsa konyowa kwa ceramic.
• Pamafunika kutsatiridwa kwa batch: nambala zambiri, ziphaso zakuthupi, ndi malipoti a QC ofanana ndi zomwe mwagula. Palibe kuchotserapo.

QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. magwero a certified waxes amakwaniritsa malire awa kuti adzipangire okha-ndipo amagawana ndondomeko yotsimikizira ndi mabwenzi oyenerera. Chifukwa ntchito ya sera yosasinthasintha si malo okwera mtengo. Ndilo gawo loyamba la umphumphu wa valavu iliyonse yokakamiza, nyumba iliyonse yapampu, chigawo chilichonse cha cobalt chopangidwa kuti chipulumuke kupsinjika kwenikweni kwa dziko.

Yang'anani kupitirira malo osungunuka. Yezerani kuchepa. Tsatani zotsalira. Tsimikizirani pa geometry yanu. Umu ndi momwe mumasiya kuthamangitsa zolakwika - ndikuyamba kutumiza magawo omwe amachita.
