Muzochitika monga kupanga makina, kusonkhanitsa zida, ndi zinthu zosungiramo zinthu, ma casters angawoneke ngati zigawo zazing'ono, koma zimakhudza mwachindunji ngati kuyenda kuli kosavuta, ngati zidazo zili zokhazikika, komanso ngati malowo ndi chete. Chifukwa chomwe mawilo a polyurethane (PU) nthawi zambiri amagwiritsidwa ntchito muzipangizo zamafakitale ndi ma carlet ndikuti amatha kuchita bwino pakati pa "mphamvu yonyamula katundu, kukana kuwonongeka, ndi kuyamwa kwadzidzidzi". Pansipa, tifotokoza mfundo yake yogwirira ntchito m'njira yosavuta kwambiri kuchokera kumalingaliro a zipangizo ndi kapangidwe kake, ndikupereka malingaliro osankha.
1. N’chifukwa chiyani polyurethane (PU) imagwiritsidwa ntchito kwambiri m’mafakitale opangidwa ndi zinthu zopangidwa ndi pulasitiki?
Ubwino wa pamwamba pa magudumu a polyurethane umachokera makamaka pa mfundo ziwiri: mphamvu ndi kusinthasintha kwa zinthu zimakhalapo nthawi imodzi.
Kusinthasintha pang'ono: Ikakakamizidwa, imasinthasintha pang'ono, zomwe zimatha kufalitsa kupsinjika kwa kukhudzana ndikuchepetsa mwayi woti pamwamba pa gudumu pawonongeke.
Mphamvu yayikulu: Poyerekeza ndi rabala wamba, PU yapamwamba kwambiri ndi yolimba komanso yosatha kung'ambika, yoyenera kugwedezeka pafupipafupi komanso kuzunguliridwa pafupipafupi.
Kugubuduzika kosalala: Pa malo ambiri osalala, mawilo a PU amakhala ndi kukana kocheperako kogubuduzika ndipo ndi osavuta kukankhira.
Kukana bwino ukalamba ndi malo osungira: M'malo opangira mafakitale monga madontho a mafuta ndi chinyezi, PU yokhala ndi mawonekedwe oyenera siifewetsedwa mosavuta kapena kusweka mwachangu (ndikulimbikitsidwabe kutsimikizira malinga ndi malo enieni osungira).
2. N’chifukwa chiyani mawilo a PU universal amakhala chete? Makamaka chifukwa cha kuphatikizana kwa "zinthu ndi kapangidwe kake"
Kutonthola sikungokhala "kufewa" kokha, komanso kulamulira kugwedezeka ndi kugwedezeka popanda kusokoneza mphamvu yonyamula katundu.
Zipangizo zimayamwa kugwedezeka: PU imakhala ndi kusinthasintha, ndipo mawilo akamadutsa m'mizere yapansi kapena m'mphepete mwaing'ono, kugwedezekako kumayamwa pang'ono ndi pamwamba pa gudumu, ndipo phokoso nthawi zambiri limakhala laling'ono kuposa la mawilo olimba a nayiloni ndi achitsulo.
Kulumikizana kokhazikika: Kulumikizana pakati pa pamwamba pa gudumu ndi pansi kumakhala kopitilira, ndipo sikutheka kuti pakhale phokoso lomveka bwino la "kugunda mwamphamvu".
Kukula ndi m'lifupi mwa mawilo ofanana: Ngati m'lifupi mwa mawilo muli lalikulu ndipo m'lifupi mwa mawilo muli bwino, kugwedezeka kumakhala kosalala ndipo phokoso limakhala lochepa.
3. N’chifukwa chiyani mawilo a PU universal amatha kunyamula kulemera? Zimatengera "pakati pa gudumu, m'lifupi mwa gudumu, bulaketi, ndi bearing"
Kuchuluka kwa katundu wonyamula katundu sikungodalira zinthu zomwe zili pamwamba pa gudumu, komanso nthawi zambiri ndi kapangidwe kake konse.
Kapangidwe ka pakati pa gudumu: kawirikawiri amagwiritsidwa ntchito ngati pakati pa nayiloni, pakati pa aluminiyamu, kapena pakati pa chitsulo. Pakati pa gudumu ndi pomwe pamathandizira kwambiri, zomwe zimatsimikiza ngati amawonongeka mosavuta akamanyamula katundu wolemera.
M'lifupi ndi m'lifupi mwa mawilo: M'lifupi mwa mawilo, kuthamanga kwa mawilo kumakhala kochepa ndipo kumakhala kokhazikika; M'lifupi mwa mawilo akuluakulu mumakhala opulumutsa ntchito ndipo mumakhala omasuka kuwoloka ming'alu ndi zopinga zazing'ono.
Kapangidwe ka mabearing: Mabearing odalirika komanso kuyenerera bwino kwa makina ndizofunikira kwambiri pa katundu wolemera, apo ayi zimakhala zosavuta kukhala zolimba mukazigwiritsa ntchito. Ndikofunikira kusankha mabearing otsekedwa kuti mugwiritse ntchito fumbi kapena malo oyeretsera.
Mphamvu ya bulaketi ndi kapangidwe ka turntable: Kaya gudumu la universal lingatembenuke bwino pansi pa katundu wolemera zimagwirizana kwambiri ndi mkanda wa turntable, makulidwe a mbale yachitsulo, ndi khalidwe la riveting/welding.
4. Mtengo wa kapangidwe ka chilengedwe chonse: chifukwa chiyani imatha kutembenuka 360 °?
Gudumu lapadziko lonse limakhala ndi gudumu ndi tebulo lozungulira. Gudumu lozungulira limazungulira chivundikirocho mozungulira njira yoyimirira kudzera mu kapangidwe ka bearing, kotero zida zimatha kusintha mwachangu njira ikakankhidwa, yoyenera malo ogwirira ntchito ndi ngolo zokhala ndi njira zopapatiza, zozungulira kangapo, komanso zofunikira pozungulira pafupipafupi.
5. Zochitika zomwe zimagwiritsidwa ntchito nthawi zambiri (zida zomwe zili zoyenera kugwiritsa ntchito mawilo a PU universal)
Kusuntha ndi kukonza zida: zowonjezera zida zamakina, matebulo ogwiritsira ntchito zida, ndi maziko a zida zoyenda (zofunika kunyamula katundu mokhazikika komanso kugwira ntchito bwino).
Magalimoto oyendera katundu ndi magalimoto oyendera katundu: kuyendetsa katundu pafupipafupi, njira zazitali (kugogomezera kwambiri kukana kuwonongeka ndi kusunga ndalama zothandizira).
Ma automation ndi mizere yopangira imafuna chiwongolero chosinthasintha komanso phokoso lochepa pamalopo (ndipo cholinga chake ndi kukhazikika ndi phokoso lochepa).
6. Malangizo osankha: Chongani mfundo 7 izi ndipo n'zokayikitsa kuti musankhe molakwika
1). Kulemera kwa katundu: Kulemera kwa zida + katundu wambiri ÷ chiwerengero cha mawilo, ndi 20% -30% dynamic load allowance yosungidwa (mkhalidwe wa katundu wosalinganika uyenera kufotokozedwa padera).
2). Dothi: epoxy/ceramic tile/simenti/chitsulo/asphalt; Kodi pali malire aliwonse, ming'alu ya nthaka, zinyalala, kapena malo otsetsereka.
3). Kagwiritsidwe ntchito ka nthawi: ka nthawi/mtunda wokwezedwa tsiku ndi tsiku; Kaya kutembenuka pafupipafupi kapena kufunikira kusintha njira yomwe ikuyenda.
4). M'lifupi ndi m'lifupi mwa mawilo: Ndikofunikira kukhala ndi m'lifupi mwa mawilo pamene nthaka ikuipiraipira; Perekani lingaliro lokulitsa pamwamba pa mawilo kuti muwonjezere katundu.
5). Ma wheel cores ndi ma bearing: Pa katundu wolemera, ndi bwino kusankha ma wheel cores olimba komanso ma bearing odalirika; Chofunika kwambiri chiyenera kuperekedwa ku ma sealing bearing m'malo omwe fumbi/kutsuka.
6). Bracket ndi brake: Ndikofunikira kugwiritsa ntchito mabuleki awiri (lock rolling + lock steering) poyika malo; Samalani makulidwe a bracket ndi kapangidwe ka turntable.
7). Malo osungira zachilengedwe ndi kutentha: Madontho a mafuta, zinthu zotsukira, asidi wofooka ndi alkalinity, malo ozizira ndi otentha, ndi zina zotero zimafuna kutsimikiziridwa kwa fomula ya zinthuzo ndi mulingo woletsa dzimbiri.
Mapeto
Chifukwa chomwe mawilo a polyurethane universal amagwiritsidwa ntchito kwambiri mumakampani opanga makina ndichakuti amatha kulinganiza kukana kutopa, kusunga ntchito, kuyamwa kwa shock, ndi kukhazikika kwa kunyamula katundu. Koma posankha, musamangoyang'ana "dzina la zinthu" kapena "nambala yonyamula katundu", komanso ganizirani mphamvu ya katundu, nthaka, malo, ndi kapangidwe ka bearing/support pamodzi. Fotokozani momveka bwino momwe ntchito ikuyendera, kenako gwirizanitsani kukula kwa gudumu, m'lifupi mwa gudumu, kapangidwe ka pakati pa gudumu, ndi kasinthidwe ka mabuleki. Moyo wa ma casters ndi zomwe ogwiritsa ntchito amagwiritsa ntchito zidzakhala zokhazikika kwambiri.
