Kuphulika kwa mfuti ndi dzina la njira yochizira pamwamba pa makina, yofanana ndi kuphulika kwa mchenga ndi kuphulika kwa mfuti. Kuphulika kwa mfuti ndi njira yochizira yozizira, yomwe imagawidwa m'magulu awiri: kuyeretsa kuphulika kwa mfuti ndi kulimbitsa kuphulika kwa mfuti. Monga momwe dzinalo likusonyezera, kuyeretsa kuphulika kwa mfuti ndiko kuchotsa zinyalala monga oxide pamwamba kuti ziwoneke bwino. Kulimbitsa kuphulika kwa mfuti ndi kugwiritsa ntchito projectile yoyenda mwachangu (60-110m/s) kuti ikhudze mosalekeza pamwamba pa workpiece yomwe ikufunika kulimbitsa. Zigawo za pamwamba ndi pamwamba pa chandamale (0.10-0.85mm) zimakakamizika kusintha izi panthawi ya kusintha kwa cyclic: 1. Kapangidwe ka microstructure kanasinthidwa; 2. Mbali yakunja yosakhala yofanana ya pulasitiki imayambitsa kupsinjika kotsalira, ndipo mkati mwake mumapanga kupsinjika kotsalira; 3. Kusintha kwa kukhwima kwakunja (RaRz). Zotsatira: Zingathe kusintha kukana kutopa kwa zinthu/zigawo, kupewa kutopa, kusintha kwa pulasitiki ndi kusweka kwa brittle, ndikuwongolera moyo wa kutopa.
Mfundo yaikulu ya ndondomeko yophulitsa mfuti:
Kuphulika kwa mfuti kumatanthauza kuti zinthu zowombera (chitsulo chowombera) zimaponyedwa pamalo ogwirira ntchito pa liwiro lalikulu komanso ngodya inayake pogwiritsa ntchito njira yamakina, kotero kuti tinthu towombera timakhala ndi mphamvu yothamanga kwambiri pamalo ogwirira ntchito. Pogwiritsa ntchito mphamvu yophatikizana ya vacuum cleaner yotsutsa vacuum pressure ndi rebound force, zinthu zowombera zimazungulira zokha mu chipangizocho. Nthawi yomweyo, zinthu zowombera ndi zonyansa zimachotsedwa motsatana kudzera mu mphamvu yoyeretsa mpweya ya chotsukira chothandizira vacuum cleaner. Ndipo njira yomwe imalola kuti ma pellets apitirize kubwezeretsedwanso. Makinawa ali ndi chosonkhanitsira fumbi kuti apange kapangidwe kopanda fumbi komanso kopanda kuipitsa, komwe sikungowonjezera magwiridwe antchito komanso kuteteza chilengedwe. Makinawa akagwiritsidwa ntchito, kukula kwa pellet ndi mawonekedwe a pellet amasankhidwa, ndipo liwiro loyenda la zida limasinthidwa ndikuwongoleredwa kuti liwongolere kuchuluka kwa projectile flow ya pellet, kuti apeze mphamvu zosiyanasiyana za projectile ndikupeza zotsatira zosiyana za kuchiza pamwamba.
Zofunikira zaukadaulo pakuphulitsa mfuti:
Mwa kuwongolera ndi kusankha kukula kwa tinthu ndi mawonekedwe a pellet, kusintha ndikukhazikitsa liwiro loyenda la makina, kuwongolera kuchuluka kwa kayendedwe ka projectile ya pellet, mphamvu zosiyanasiyana za projectile ndi zotsatira zosiyanasiyana zochizira pamwamba zingapezeke. Njira yophulitsira kuwombera ndi zida zophulitsira kuwombera zimawongolera momwe pamwamba pake padzachitidwira chithandizo kudzera mu magawo atatu malinga ndi malo osiyanasiyana oti agwiritsidwe ntchito. Sankhani kukula ndi mawonekedwe a pellet; Liwiro loyenda la zida; Kuchuluka kwa kuyenda kwa ma pellet. Magawo atatu omwe ali pamwambapa amagwirizana kuti apeze zotsatira zosiyanasiyana zochizira ndikuwonetsetsa kuti pamwamba pake padzakhale kukhwima bwino. Mwachitsanzo: pogwiritsa ntchito chitsulo cha S330, flow 10A, kukonza pamwamba pa konkire ya C50, kumatha kufika kukhwima kwa 90; Mwa kukonza pamwamba pa phula, wosanjikiza wosefukira madzi ukhoza kuchotsedwa ndipo kukhwima ndi 80. Mukagwira mbale zachitsulo, muyezo wa ukhondo wa SA3 ukhoza kufikika.
Kuphulitsa mfuti ndi njira yoyeretsera, kulimbitsa (kuphulitsa mfuti) kapena kupukuta chogwirira ntchito ndi makina ophulitsa mfuti, omwe amagwiritsidwa ntchito pafupifupi m'mafakitale onse omwe amagwiritsa ntchito zitsulo, kuphatikizapo ndege, magalimoto, zomangamanga, kuponyera miyala, kupanga zombo, njanji ndi mafakitale ena ambiri. Pali njira ziwiri: kuphulitsa mfuti kapena kuphulitsa mchenga.
Choyamba: makina ophulitsira mfuti:
1. Makina ophulitsira mfuti amasintha mphamvu ya injini mwachindunji kukhala mphamvu yamphamvu yowononga mwa kuzunguliza injini ya turbine.
2, mphamvu ya impeller iliyonse kuyambira pafupifupi 60 kg pamphindi mpaka 1200 kg pamphindi.
3, kuti mugwiritse ntchito ma accelerator ambiriwa, gwiritsani ntchito wheel mill, momwe zigawo zazikulu kapena madera akuluakulu a zigawo ziyenera kukhala ndi dzimbiri, kuchotsedwa, kuchotsedwa, kuchotsedwa kapena kutsukidwa.
4, Nthawi zambiri, njira yonyamulira ziwalo zomwe ziponyedwe idzafotokoza mtundu wa makina: kuyambira pa desktops zosavuta mpaka ma manipulators okhazikika okha kwa opanga magalimoto osiyanasiyana, kudzera mu ma roller conveyors ndi ma lamba descaling systems.
Chachiwiri: makina ophulitsira mchenga:
1, makina ophulitsira mchenga angagwiritsidwe ntchito ngati chophulitsira kapena chophulitsira, chophulitsira chimayendetsedwa ndi mpweya wopanikizika ndipo chimayikidwa ku zigawo zake ndi nozzle.
2, pa ntchito zapadera, chisakanizo cha media-water chingagwiritsidwe ntchito, chomwe chimatchedwa wet sandblasting.
3, mu mpweya ndi mchenga wonyowa, nozzle ikhoza kuyikidwa pamalo okhazikika, kapena ikhoza kugwiritsidwa ntchito pamanja kapena ndi nozzle operator kapena PLC programmed automation system.
4, ntchito yopukutira mchenga imasankha njira yopukutira, nthawi zambiri imatha kugwiritsa ntchito njira iliyonse yopukutira youma kapena yomasuka.
