chikhomo
Kutanthauzira kwazinthu ndi njira yayikulu
Gasket yakuda yamphamvu kwambiri ndi gasket yomwe imapanga filimu yakuda ya Fe₃O₄ oxide pamwamba pa chitsulo cha alloy kudzera mu okosijeni wamankhwala (mankhwala akuda), okhala ndi makulidwe a filimu pafupifupi 0.5-1.5μm. Zinthu zake zoyambira zimakhala 65 manganese chitsulo kapena 42CrMo aloyi chitsulo, ndipo pambuyo kuzimitsa + kutentha mankhwala, kuuma akhoza kufika HRC35-45.
Zinthu zazikulu ndi mawonekedwe
Zofunika:
65 manganese chitsulo (kuthokokera bwino, ntchito masika gaskets);
42CrMo aloyi zitsulo (mphamvu mkulu, ntchito gaskets lathyathyathya).
Mawonekedwe:
Zida zamakina apamwamba: mphamvu zamakomedwe ≥1000MPa, zoyenera zochitika zolemetsa;
High kutentha kukana: okusayidi filimu ndi khola m'munsimu 200 ℃, amene ndi bwino kuposa kanasonkhezereka wosanjikiza;
Palibe chiwopsezo cha hydrogen embrittlement: njira ya okosijeni yamankhwala imapewa kuyika kwa hydrogen embrittlement, yoyenera zida zolondola.
Ntchito ndi zochitika zoyenera
Ntchito:
Kulimbana ndi kugwedezeka kwakukulu kapena kunyamula katundu kuti ma bolt asamasuke;
Sungani magwiridwe antchito m'malo otentha kwambiri (monga kulumikizana kwa silinda ya injini).
Zochitika:
Injini yamagalimoto (ma cylinder head bolts), makina opangira migodi (kulumikizana ndi crusher), zida zamagetsi zamagetsi (spindle flange).
Kuyika ndi kukonza
Kuyika:
Mukagwiritsidwa ntchito ndi mabawuti amphamvu kwambiri, limbitsani molingana ndi torque coefficient (monga 0.11-0.15);
Tsukani mafuta pamwamba musanayike kuti muwonetsetse kuti filimu ya okusayidi imamangiriridwa mwamphamvu ku gawo lapansi.
Kusamalira:
Yang'anani nthawi zonse kukhulupirika kwa filimu ya okusayidi, ndipo mbali zowonongeka ziyenera kuchitidwanso zakuda;
Pewani kumizidwa kwa nthawi yayitali mu electrolyte kuti filimu ya oxide isawonongeke.
Gulani malingaliro
Sankhani zipangizo malinga ndi katundu: 65 manganese zitsulo ndi oyenera zotanuka zofunika, 42CrMo ndi oyenera malo amodzi katundu mkulu;
M'malo otentha kwambiri (> 300 ℃), zokutira za ceramic kapena zitsulo zosapanga dzimbiri ziyenera kugwiritsidwa ntchito m'malo mwake.
Kufananiza ndi kusankha kalozera wa gaskets zazikulu zitatu
| Mtundu | Electroplated kanasonkhezereka gasket | Gasket yamitundu yosiyanasiyana | Gasket yakuda yamphamvu kwambiri |
| Ubwino waukulu | Mtengo wotsika, wamphamvu zosunthika | High dzimbiri kukana, chizindikiritso mtundu | Mphamvu yapamwamba, kukana kutentha kwakukulu |
| Mayeso opopera mchere | Maola 24-72 opanda dzimbiri loyera | Maola 72-120 opanda dzimbiri loyera | Maola 48 opanda dzimbiri |
| Kutentha koyenera | -20 ℃ ~ 80 ℃ | -20 ℃ ~ 100 ℃ | -40 ℃ ~ 200 ℃ |
| Zochitika zenizeni | Makina wamba, chilengedwe chamkati | Zida zakunja, chilengedwe chonyowa | Injini, zida zogwedezeka |
| Chitetezo cha chilengedwe | Njira yopanda cyanide imagwirizana ndi RoHS | Hexavalent chromium iyenera kutsatira REACH, trivalent chromium ndiyotetezeka ku chilengedwe. | Palibe kuwononga zitsulo zolemera |
Malingaliro osankha:
Zofunikira pazachuma: Electroplated kanasonkhezereka gaskets, oyenera zochitika wamba mafakitale;
Malo okhala ndi dzimbiri: Ma gaskets achikuda, amaika patsogolo njira ya chromium yopanda chromium;
Kulemera kwakukulu / kutentha kwakukulu: Ma gaskets akuda amphamvu kwambiri, ofananira mphamvu ya bawuti (monga 42CrMo ya 10.9 grade bolts gasket).
