Kuphulika kwa kuwombera ndi dzina la njira yochizira pamakina, yofanana ndi kuphulika kwa mchenga ndi kuwomba. Kuwombera kuwombera ndi njira yoziziritsira yozizira, yomwe imagawidwa kukhala kuyeretsa kuwombera ndi kulimbitsa kuwombera. Monga momwe dzinalo likusonyezera, kuyeretsa kuwombera ndi kuchotsa zonyansa monga oksidi pamwamba kuti ziwoneke bwino. Kulimbitsa kuphulika kwa kuwombera ndiko kugwiritsa ntchito projekiti yothamanga kwambiri (60-110m/s) kuti ikhudze mosalekeza pamwamba pa chogwiriracho kuti chilimbikitsidwe. Pamwamba ndi pamwamba pa chandamale (0.10-0.85mm) amakakamizika kusintha zotsatirazi pa cyclic deformation: 1. Microstructure inasinthidwa; 2. Kunja kopanda yunifolomu kopangidwa ndi pulasitiki kumayambitsa kupsinjika kotsalira, ndipo mkati mwake kumatulutsa kupsinjika kotsalira; 3. Kusintha kwamphamvu kwakunja (RaRz). Zotsatira: Itha kupititsa patsogolo kukana kwamphamvu kwa zinthu / magawo, kupewa kutopa, kupunduka kwa pulasitiki ndi kusweka kwa brittle, ndikusintha moyo wotopa.
Mfundo ya ndondomeko ya kuphulika kwa mfuti:
Kuwombera kuwombera kumatanthauza kuti zida zowombera (chitsulo chowombera) zimaponyedwa kumalo ogwirira ntchito pamtunda wothamanga kwambiri ndi Angle inayake ndi njira yamakina, kotero kuti tinthu tating'onoting'ono timakhudza kwambiri ntchito. Pansi pa ophatikizana zochita za vacuum zotsukira vacuum zoipa kuthamanga ndi rebound mphamvu, kuwombera zakuthupi circulate yokha mu zida. Nthawi yomweyo, zida zowombera ndi zonyansa zomwe zidatsukidwa zimabwezedwa motsatana kudzera pakuyeretsa mpweya kwa chotsukira chothandizira. Ndipo njira yomwe imalola kuti ma pellets apitirire kusinthidwanso. Makinawa ali ndi chosonkhanitsa fumbi kuti akwaniritse zomanga zopanda fumbi komanso zosaipitsa, zomwe sizimangowonjezera bwino komanso zimateteza chilengedwe. Makinawa akagwiritsidwa ntchito, kukula kwa pellet ndi mawonekedwe a pellet amasankhidwa, ndipo liwiro loyenda la zida limasinthidwa ndikuwongoleredwa kuti liwongolere kuchuluka kwa projekiti ya pellet, kuti apeze mphamvu yosiyana ya projectile ndikupeza chithandizo chosiyana chapamwamba. zotsatira.
Zofunikira paukadaulo pakuwombetsa mfuti:
Poyang'anira ndikusankha kukula kwa tinthu ndi mawonekedwe a pellet, kusintha ndikuyika liwiro la makina, kuwongolera kuchuluka kwa ma projectile a pellet, mphamvu yosiyana ya projectile ndi zotsatira zosiyanasiyana za chithandizo chapamwamba zitha kupezeka. The kuwombera ndondomeko kuphulika ndi kuwombera kuwombera zida kulamulira chikhalidwe padziko pambuyo mankhwala kudzera magawo atatu malinga ndi pamwamba osiyana kuchitiridwa. Sankhani kukula ndi mawonekedwe a pellet; Kuthamanga kwa maulendo a zipangizo; Kuchuluka kwa ma pellets. Magawo atatu omwe ali pamwambawa amagwirizana wina ndi mnzake kuti apeze zotsatira zosiyanasiyana zamankhwala ndikuwonetsetsa kuti pamakhala roughness yamtunda pambuyo powombera. Mwachitsanzo: kugwiritsa ntchito S330 chitsulo chowombera, kutuluka 10A, chithandizo cha C50 pamwamba pa konkire, chikhoza kufika roughness ya 90; Pochiza pamwamba pa asphalt, kusefukira kwa madzi kumatha kuchotsedwa ndipo roughness ndi 80. Pogwira mbale zachitsulo, muyezo waukhondo wa SA3 ukhoza kufika.
Kuwombera kuwombera ndi njira yoyeretsera, kulimbikitsa (kuwombera kuwombera) kapena kupukuta workpiece ndi makina owombera, omwe amagwiritsidwa ntchito pafupifupi mafakitale onse omwe amagwiritsa ntchito zitsulo, kuphatikizapo ndege, magalimoto, zomangamanga, kuponyera, kumanga zombo, njanji ndi mafakitale ena ambiri. . Pali njira ziwiri: kuphulitsa kuwombera kapena kuphulitsa mchenga.
Choyamba: makina opangira magetsi:
1. Makina owombera owombera amatembenuza mphamvu yamagalimoto molunjika kukhala mphamvu ya abrasive mphamvu pozungulira chowongolera cha turbine.
2, mphamvu ya choyikapo chilichonse kuchokera pa 60 kg pamphindi mpaka 1200 kg / mphindi.
3, kugwiritsa ntchito kuchuluka kwakukulu kwa ma accelerators, gwiritsani ntchito mphero yamagudumu, momwe mbali zazikulu kapena zigawo zazikulu ziyenera kukhala za dzimbiri, kutsika, kuwononga, kusenda kapena kuyeretsa.
4, Nthawi zambiri, njira yonyamulira magawo omwe adzaponyedwe adzafotokozera mtundu wa makina: kuchokera pa desktops zosavuta kupita kuzinthu zophatikizira zodziwikiratu za opanga magalimoto osiyanasiyana, kudzera pa ma conveyors ndi makina otsitsa lamba.
Chachiwiri: makina ophulitsira mchenga:
1, makina ophulika a mchenga angagwiritsidwe ntchito ngati chowombera kapena chowombera, sing'anga yophulika imathamangitsidwa ndi mpweya woponderezedwa ndikuwonetseredwa ku zigawo zake ndi nozzle.
2, pa ntchito zapadera, osakaniza atolankhani-madzi angagwiritsidwe ntchito, omwe amatchedwa wet sandblasting.
3, mumlengalenga ndi kunyowa sandblasting, nozzle imatha kukhazikitsidwa pamalo okhazikika, kapena itha kuyendetsedwa pamanja kapena ndi opareshoni ya nozzle kapena makina opangidwa ndi PLC.
4, ntchito yopukutira mchenga imasankha kusankha kwa media media, nthawi zambiri amatha kugwiritsa ntchito mtundu uliwonse wa media wowuma kapena waufulu.
