Mapulawu a makina a ulimi olimba kwambiri komanso osatha ntchito - osatha kuimitsidwa polima kwambiri nthaka yakuda. Chithunzi Chowonetsedwa

Mapulawo a makina a ulimi amphamvu kwambiri komanso osatha ntchito - osatha kuimitsidwa akamalima kwambiri nthaka yakuda.

Kufotokozera Kwachidule:

Tsamba la pulawo limapangidwa ndi chitsulo cha boron cholimba kwambiri komanso chosatha, ndipo tsamba lake limachizidwa ndi njira yapadera yotenthetsera kutentha, zomwe zimapangitsa kuti nthaka ilowe bwino komanso kuti isamawonongeke nthawi yayitali. Kapangidwe kake kolunjika bwino ka pamwamba kamachepetsa kukana kulima, kumathandizira kutembenuza ndi kusweka kwa nthaka. Yoyenera malo osiyanasiyana a nthaka, kuphatikizapo minda youma ndi minda ya mpunga, ndi gawo labwino kwambiri lolima mathirakitala ndi ma mini-tillers.

Chomera cholima, monga gawo lalikulu la pulawo la moldboard, chimakhudzana mwachindunji ndi nthaka ndipo chimapirira kukangana kwakukulu ndi kukhudzidwa. Mitundu yathu ya zolima zaulimi idapangidwa makamaka kuti ithane ndi malo ovuta komanso osinthasintha a ulimi, odzipereka kupatsa ulimi wamakono njira zolima mozama, zogwira mtima, komanso zosunga mphamvu. Kaya ndi dongo lolimba kapena mchenga wolimba, zolima zathu, zomwe zimakhala ndi mphamvu zabwino kwambiri zolowera m'nthaka komanso kukana kuwonongeka, zimathandiza ogwiritsa ntchito kupeza ulimi wapamwamba komanso kuchepetsa ndalama zosinthira.

Zipangizo ndi Njira Zapakati: Chogulitsachi chimagwiritsa ntchito chitsulo cha rare earth alloy boron chapamwamba kwambiri ngati maziko. Kudzera mu die forging yotentha kwambiri, kapangidwe ka mkati mwa chitsulocho kamapangidwa mosalekeza komanso mokwanira, zomwe zimathandizira kwambiri kuchulukana ndi kulimba kwa matrix.

Ukadaulo wapamwamba wochizira kutentha: Pogwiritsa ntchito njira zozimitsira kutentha kwa isothermal komanso njira zoziziritsira pamwamba, nsonga ya fosholo imapeza kuuma kwa HRC 48-52, pomwe chogwiriracho chimasunga kulimba kwambiri. Khalidwe la "kunja kolimba, mkati mwake" limatsimikizira kuti nsonga ya fosholo imakhala yakuthwa ngakhale itakhala ikukangana kwa nthawi yayitali, pomwe imateteza bwino kugwedezeka kwa miyala yobisika ndi mizu ya mitengo m'munda, kuteteza kusweka.

Kapangidwe kodzinola: Kapangidwe kake kapadera kamatsimikizira kuti pamwamba pa nsonga ya fosholo pamakhala ngodya yabwino kwambiri ndi nthaka panthawi yogwira ntchito. Pamene nthawi yogwirira ntchito ikuwonjezeka, nsonga ya fosholo imadzichepetsera yokha, kusunga ngodya yakuthwa yodulira, motero kuchepetsa kukana kulima ndikuwongolera magwiridwe antchito.

Kugwira bwino ntchito kwa nthaka: Kulowera bwino kwa nthaka komanso kapangidwe kake kopindika kumatha kudula mwachangu zotsalira za nthaka, kuchepetsa kutsekeka kwa nthaka, kuonetsetsa kuti nthaka ikulimba, komanso kuonetsetsa kuti nthaka yaphimbidwa bwino, zomwe zimathandiza kubzala pambuyo pake.

Kukana kukalamba kwa nthawi yayitali komanso moyo wautali: Poyerekeza ndi chitsulo wamba cha 65Mn, kukana kukalamba kumawonjezeka ndi nthawi 2-3. Pansi pa nthaka yabwinobwino ya mchenga, malo olimidwa amatha kufika maekala mazana ambiri kapena kuposerapo mu nyengo imodzi, zomwe zimachepetsa kwambiri nthawi yoti zinthu zisinthe m'munda.

Kugwirizana kwakukulu: Pali mitundu yonse ya zinthu zomwe zilipo, zomwe zikuphatikizapo mitundu yosiyanasiyana kuyambira mapulawu opepuka mpaka mapulawu olemera a mitsinje isanu. Imagwirizana ndi Renault, Reiken, Bellotta, ndi mitundu ina yambiri ya mathirakitala apakhomo, yokhala ndi mabowo okhazikika bwino komanso malo ena osavuta kuwasintha.
