Ubwino wa kukonza ndodo zokoka pogwiritsa ntchito laser

Ndodo zodulira mafuta ndi chida chofunikira kwambiri komanso chofunikira kwambiri pakutulutsa mafuta. Zimagwira ntchito m'malo ovuta kwa nthawi yayitali ndipo zimatha kuwonongeka mosiyanasiyana monga kuwonongeka ndi dzimbiri, zomwe zimafupikitsa nthawi yogwira ntchito ndikuwonjezera nthawi yosinthira, zomwe zimapangitsa kuti mafuta azigwiritsidwa ntchito mopitirira muyeso. Komabe, chifukwa cha kupanga ndi kugwiritsa ntchito ukadaulo wa laser cladding, kukonzanso ndikugwiritsanso ntchito ndodo zodulira mafuta kwakhala kotheka, zomwe sizimangochepetsa mtengo wopangira mafuta, komanso zimawonjezera phindu lazachuma la mafuta.

1. Mfundo yaukadaulo wokonza zophimba ndi laser pa ndodo zokoka

Kukonza ma cladding a laser a ndodo zonyowa ndi nthambi yofunika kwambiri paukadaulo wosintha pamwamba pa zinthu. Mwachidule, imagwiritsa ntchito kuwala kwa laser kwamphamvu kwambiri ngati gwero la kutentha kuti ipereke molondola ufa wa alloy ku gawo lowonongeka la ndodo yonyowa. Pansi pa mphamvu yayikulu ya kuwala kwa laser, ufa wa alloy umasungunuka mwachangu ndikusungunuka nthawi yomweyo ndi wosanjikiza woonda wa zinthu pamwamba pa sucker rod matrix. Pambuyo pozizira mwachangu, wosanjikiza womwe umalumikizidwa ndi zitsulo ku matrix umapangidwa pamwamba pa sucker rod.

2. Poyerekeza ndi njira zachikhalidwe zokonzera, kukonza ndodo za pampu pogwiritsa ntchito laser cladding kuli ndi ubwino waukulu, womwe umaonekera kwambiri m'mbali zotsatirazi:

1) Mphamvu yolumikizira zitsulo: Kuphimba kwa laser kumagwiritsa ntchito kuwala kwa laser kokhala ndi mphamvu zambiri kuti kusungunuke pang'ono pamwamba pa chinthu chogwirira ntchito, ndipo nthawi yomweyo kumasungunula ufa wa alloy kuti upange chophimba cholimba chomwe chimalumikizidwa ndi zitsulo ku substrate. Njira yolumikizira iyi sikuti imangokhala ndi mphamvu zambiri, komanso ili ndi kapangidwe kolimba kopanda zolakwika monga ming'alu.

2) Kukana kuvala ndi kukana dzimbiri: Kuphimba kwa laser kumatha kupanga gawo la alloy lokhala ndi kukana dzimbiri ndi kukana kuvala pamwamba pa zinthu wamba zachitsulo cha kaboni, motero kumawonjezera kwambiri kukana kuvala ndi kukana dzimbiri kwa ndodo ya pampu ndikuwonjezera nthawi yake yogwirira ntchito.

3) Kuchepetsa ndalama ndi kugwiritsa ntchito mphamvu: Ukadaulo wa laser cladding ukhoza kukonzekera malo a alloy ogwira ntchito bwino kwambiri pa substrates zotsika mtengo, zomwe zimapulumutsa ndalama za zinthu. Nthawi yomweyo, chifukwa cha kutentha pang'ono komanso kusintha kwa njira yopangira laser cladding, kuchuluka kwa kukonza komwe kumachitika pambuyo pake kumakhala kochepa, zomwe zimachepetsanso kugwiritsa ntchito mphamvu ndi ndalama zogwirira ntchito.

4) Ubwino waukulu wa cladding: Chophimba chomwe chimapezeka pogwiritsa ntchito laser cladding chili ndi dilution rate yotsika (nthawi zambiri yochepera 5%) ndipo chimalumikizidwa mwamphamvu ndi zitsulo kapena chimafalikira pakati pa nkhope ndi substrate. Kuphatikiza apo, kapangidwe ka cladding ndi dilution zimatha kulamulidwa, zomwe zimapangitsa kuti cladding ikhale yabwino kwambiri. 5. Kusinthasintha kwabwino: Ukadaulo wa laser cladding ukhoza kukonza bwino cladding pamalo ogwirira ntchito okhala ndi mawonekedwe ovuta, ndipo ndi woyenera kukonza ndodo za pampu za zipangizo ndi mawonekedwe osiyanasiyana.
