Ndi mavuto ati omwe angakhalepo kukhululuka ndi kuzirala?

Lero, ndikutengani kuti mumvetsetse kuti mavuto amtundu wa chithandizo cha kutentha omwe angachitike panthawi yothetsa ndi kuzizilitsa kwamakhululukidwe ndi makamaka: kuuma kokwanira mutatha kuzimitsa, kuuma kosafanana mdziko lothedwa, kusakwanira kuzimitsa kolimba; kuuma kwakukulu kwa pachimake mutatha kuzimitsa; Kuthetsa kwakukulu; kuzimitsa kulimbana; Kuwala kwapadziko sikokwanira pambuyo pa kuzimitsa mafuta.

Chotsatira, ndikukuwuzani mwatsatanetsatane za zovuta zamtunduwu ndi mayankho amakhululukidwe mukamazizira ndikuzizira:

Kuuma kosakwanira komanso kuzama kosakwanira: Kutsika kwakutha kozimitsa ndi chifukwa chosakwanira kuzimiririka, kuuma kosafanana komanso kuuma kokwanira kosakwanira kwa kukhululuka. Komabe, malinga ndi zenizeni zakuthupi, mawonekedwe, kukula ndi kutentha kwa kutentha kwa zomwe zakhululukidwa, zimatha kugawidwa pakatenthedwe Pali zinthu zosiyanasiyana monga kuzirala kokwanira m’magawo, kuzirala kokwanira pamagawo otentha ndi otsika, ndi kutentha kochepa kotsika pang’onopang’ono. Mwachitsanzo. Kukhululuka kwakanthawi kochepa komanso kwapakatikati, kuuma kokwanira kosakwanira nthawi zambiri kumayambitsidwa ndi kuzizira kokwanira pakati komanso magawo otentha. Kukhululuka ndi ma modulus akulu kumafunikira wosanjikiza wolimba, ndikofunikira kwambiri kuti muwonjezere kutentha kotsika. Pofuna kuzimitsa mafuta, nthawi zambiri, mafuta amakhala ndi gawo lalifupi lamafilimu, mpweya wozizira mwachangu, komanso kuziziritsa mwachangu, komwe kumatha kupeza kulimba kwakukulu ndi yunifolomu kuzimitsa komanso kuzama kokwanira.

Momwe magwiridwe antchito amagwiritsidwira ntchito zimakhudzanso kuzimitsa kozizira. Ndikofunikira kuti mafuta omwe azimitsa asayende bwino, ndikukonzekeretsa ndikugwiritsa ntchito chida chabwino chosakanikirana kuti chikhale bwino. Kuchulukitsa kutentha kozizira kwambiri kwa njira yothetsera yomwe imagwiritsidwa ntchito kumatha kukulitsa kuzama kwazitsulo zolimba. Pankhani yogawidwa komweko kwa kaboni m’galimoto ya carburized, kugwiritsa ntchito mafuta ozimitsa omwe ali ndi kutentha kotsika kwambiri kumathandizira kupeza kuzama kolimba. Chifukwa chake, kugwiritsa ntchito mafuta ozimitsa ndi kuziziritsa mwachangu kumatha kufupikitsa nthawi yolemetsa ya workpiece mofananamo. Mungapeze kuya kofunika kwa kuzimitsa ndi kuumitsa wosanjikiza. Kukula kwakukulu kwa chinyezi cholimbitsidwa ndi carburized kumafunikira, kuwonekera kwakukulu kwa njirayi pakufupikitsa nthawi ya carburizing.

Kuuma kwa pachimake pakutha kuzimitsa kumakhala kwakukulu kwambiri: vuto ili limatha kukhala logwirizana ndi kuzizira kwachangu kwa sing’anga kapena kutentha kotsika kwambiri kwapakatikati. Limodzi mwa mayankho ndikusintha mafuta omwe azimitsa kuti akwaniritse zofunikira. Njira yachiwiri ndikulumikizana ndi wopanga sing’anga wozimitsa ndikuwonjezera zowonjezera zowonjezera kuti muchepetse mafuta ozimitsa kutentha kwapakati komanso kutsika. Njira yachitatu ndikusinthira kuzitsulo ndizovuta zochepa.

Kuthetsa vuto lakusintha: Kuzimitsa mapangidwe kwapangitsa mafakitale ambiri kulingalira. Malinga ndi mwambo, yankho lavuto lamatenda nthawi zambiri limakhudza madipatimenti angapo, ndipo yankho nthawi zambiri limakhala lokwanira. Zomwe zimayambitsa kusinthaku zimachitika chifukwa cha kuzirala kokwanira komanso kuzizira kosagwirizana, ndipo pamaziko awa, njira yankho yothetsera kuzirala ndikuyesera kukwaniritsa kuzirala yunifolomu ikufunsidwa. Njira zokulitsira kuzizirako kuziziritsa ziyenera kuwonjezedwa pokhapokha ngati njira zomwezo zasankhidwa moyenera. Ikhoza kuthana ndi vuto lodzichotsa pakakhululukidwa kwambiri. Mwachitsanzo, kusinthika kwa dzenje lamkati lamkati la kulipira nthawi zambiri kumayambitsidwa chifukwa chakukhala kocheperako kwazizira lazizira la mafuta osankhidwa ozimitsa, kapena gawo lalitali kwambiri lamafuta amafuta. Kuchulukitsa kutentha kwamafuta kwambiri ndikuwonjezera kuzirala kwamafuta munjira yonse yozizira kumatha kuthana ndi vuto lakukula kwa dzenje lamkati lamkati. Kwa okhululuka, makamaka kukhululukidwa kolondola, kusankha bwino ndikugwiritsa ntchito mafuta ozimitsa mafuta ndichofunikira kwambiri pakuwongolera kusunthika.

Kuthetsa kulimbana kwa kukhululuka: Vutoli limapezeka makamaka pakuzimitsa kotentha. Sankhani malo abwino otsekera madzi, monga PAG yotseka sing’anga yomwe imagwiritsidwa ntchito kwambiri kunyumba ndi kunja kuti ikalowe m’malo mwa madzi apampopi oyamba, vutoli lidzathetsedwa. PAG sing’anga imagwiritsidwa ntchito potenthetsa ndikuzimitsa. Mkulu ndi yunifolomu kuzimitsa kuuma ndi kwambiri ndi khola anaumitsa wosanjikiza angapezeke, ndi chiopsezo kuzimitsa akulimbana ndi laling’ono kwambiri.

Vuto lowala: Pazifukwa zomwe mbali iyi imafunika, mafuta ozimitsa owala kapena mafuta ozimitsa owala ayenera kugwiritsidwa ntchito. Nthawi zambiri, kuzirala kwamafuta ozimitsa owala sikokwanira mokwanira ngati kuwala kwa mafuta ozimitsa owala ndikwabwino, ndipo kuwala kwa mafuta ozimitsa omwe ali ozizira kwambiri sikokwanira. Kuphatikiza apo, kuwala kwa mafuta otentha nthawi zambiri kumakhala kovuta. Mutha kusintha mafuta kapena kuwonjezera zowonjezera kuti mukhale ndi kuwala.
