Zomwe zimafunikira pakuyala kwa vacuum pamalo ogwiritsira ntchito

Njira yokutira vacuum ili ndi zofunika kwambiri pamagwiritsidwe ntchito.Pakuti ochiritsira vacuum ndondomeko, zofunika zake zazikulu za ukhondo zingalowe ndi: palibe anasonkhanitsa gwero kuipitsa pa mbali kapena pamwamba pa zida mu vakuyumu, pamwamba pa chipinda vakuyumu ndi yosalala komanso opanda minofu yofewa, pores ndi ngodya danga. , kotero kuwotcherera mu makina otsekemera sikungakhudze mpweya, ndipo makina otsekemera otsekemera sangagwiritse ntchito mafuta ngati mafuta.Dongosolo la vacuum lopanda mafuta lopanda mafuta liyenera kupewa kutengera mpweya wamafuta pachiyero, magwiridwe antchito kapena mawonekedwe apamwamba a sing'anga yogwirira ntchito.Dongosolo lachitsulo chapamwamba kwambiri la vacuum nthawi zambiri limagwiritsa ntchito 1Cr18Ni9Ti ngati zomangira.Malo opangira ma labotale kapena malo ogwirira ntchito komwe makina opaka vacuum ayenera kukhala aukhondo komanso aukhondo.

Pogwiritsa ntchito zokutira vacuum, mankhwala oyeretsa pamwamba ndi ofunika kwambiri.Kwenikweni, magawo onse asanayambe kulowetsedwa m'chipinda chovundikira, ayenera kudutsa njira yoyeretsera isanakwane kuti akwaniritse kutsitsa, kuchotseratu komanso kutaya madzi m'thupi la ntchitoyo.

Magwero akuluakulu a kuipitsidwa kwapadziko la magawo odzaza ndi: fumbi, thukuta, mafuta, phala lopukuta, mafuta, mafuta odzola ndi zinthu zina zidzatsatiridwa panthawi yokonza, kutumiza, kulongedza ndi njira zina;Gasi adsorbed ndi odzipereka padziko zida mbali;Filimu ya oxide inapangidwa pamwamba pa zigawo za makina opaka mu mpweya wonyowa.Pakuipitsidwa kuchokera ku magwero awa, ambiri aiwo amatha kuchotsedwa ndi degreasing kapena kuyeretsa mankhwala.

Osasunga zinthu zoyeretsedwa mumlengalenga.Pofuna kuchepetsa kuipitsidwa kwa fumbi ndikuyeretsa kusungirako ntchito, nthawi zambiri mumagwiritsa ntchito makabati oyeretsera kapena zida zotsekedwa kuti musunge ntchitoyo.Galasi gawo lapansi liyenera kusungidwa mu chidebe cha aluminiyamu chatsopano, chomwe chingachepetse kutengeka kwa mpweya wa hydrocarbon.Chifukwa zotengera za aluminiyamu zomwe zakhala ndi okosijeni zatsopano zitha kukopa ma hydrocarbons.Malo omwe amakhudzidwa ndi nthunzi wamadzi kapena osakhazikika kwambiri nthawi zambiri amasungidwa mu uvuni wowumitsa vacuum.

Mfundo zofunika za ndondomeko vakuyumu ❖ kuyanika pa chilengedwe makamaka zikuphatikizapo: ukhondo mkulu mu chipinda zingalowe, fumbi wopanda mu chipinda ❖ kuyanika, etc. M'madera ena, mpweya chinyezi ndi mkulu, kotero pamaso plating, osati ayenera kuyeretsa. zigawo za gawo lapansi ndi vacuum chipinda, komanso ayenera kuchita ntchito yophika ndi degassing.Kuphatikiza apo, pofuna kupewa mafuta kuti asalowe m'chipinda cha vacuum, m'pofunikanso kutchera khutu ku kubwereranso kwamafuta ndi njira zotsekereza mafuta a pampu yotulutsa mafuta.
