Nsonga ya pulawo yosinthika yokhala ndi mitu iwiri 173332 173331 makina aulimi omwe satha kutopa, manganese chitsulo cholimba ...
Nsonga za pulawo za 173332 ndi 173331 zokhala ndi mitu iwiri ndi zinthu zofunika kwambiri pamakina amakono olima ulimi, omwe adapangidwira makamaka ntchito zolima zolimba komanso zogwira mtima kwambiri. Mitundu yonseyi imagwiritsa ntchito kapangidwe kofanana kamene kamasinthika, kudutsa malire a nthawi yochepa ya pulawo wamba wokhala ndi mitu imodzi, cholinga chake ndi kuchepetsa ndalama zogwirira ntchito kwa ogwiritsa ntchito ndikuwonjezera magwiridwe antchito a ulimi.
1, kapangidwe kosinthika ndi moyo wautumiki wawiri
Chochititsa chidwi kwambiri pa nsonga ziwirizi za pulawu ndi kapangidwe kake kapadera kosinthasintha mutu. Pamene nsonga ya mbali imodzi ya pulawu ikhala yofooka chifukwa cha kukangana panthawi yogwira ntchito, ingochotsani ndikutembenuza njira kuti mupitirize kugwiritsa ntchito m'mphepete watsopano womwe uli mbali inayo. Kapangidwe kameneka kakutanthauza kuti poyerekeza ndi nsonga yokhazikika ya pulawu yokhala ndi mutu umodzi, 173332 ndi 173331 imapereka nthawi yogwira ntchito kawiri, kuchepetsa zinthu zosungiramo zinthu zina ndikuchepetsa kwambiri nthawi yamtengo wapatali yaulimi yomwe imawonongedwa chifukwa cha nthawi yopuma ya zida zosinthira.
2, kugawa kutentha ndi kukana kuvala bwino
Pofuna kuthana ndi kuwonongeka kwa nsonga za pulawo chifukwa cha nthaka youma kapena yolemera, zinthu ziwirizi zayang'aniridwa mosamala pankhani ya zinthu ndi njira yochizira kutentha:
Kusankha zinthu: Thupi lalikulu limapangidwa ndi zinthu zolimba kwambiri monga 65Mn kapena boron steel, zomwe zimaonetsetsa kuti substrateyo ndi yolimba komanso yolimba.
Chithandizo cha kutentha kwa magawo: Pogwiritsa ntchito njira zamakono zopangira, pamwamba pa nsonga ya pulawo (pokhudzana ndi nthaka) pazimitsidwa kuti pakhale kuuma kwa HRC 45-57, zomwe zimasonyeza kukana bwino kuwonongeka; Malo ozungulira dzenje loyika bolt amakhala olimba kuti apewe kusweka kwa mabala akakhudzidwa ndi miyala.
Kuuma kwa gawo: Njira zina zapamwamba zimaphatikizapo kuwotcherera alloy yolimba pamphepete kuti iwonjezere kuuma kufika pa HRC 60 kapena kupitirira apo, zomwe zimapangitsa kuti nthaka yamchenga isawonongeke kwambiri.
4、Kuyenda bwino kwa nthaka komanso kusinthasintha
Malo osalala: Thupi la nsonga ya pulawo limagwiritsa ntchito kapangidwe kofanana ndi arc, komwe kungathandize kuchepetsa kukana kukoka, kulola nthaka kukwera bwino ndikuzungulira khoma la pulawo, motero kuchepetsa kugwiritsa ntchito mafuta kwa thirakitala ndikuwonjezera magwiridwe antchito.
Kugwirizana kwakukulu: Ma Model 173332 ndi 173331 ndi zida zosinthira zapamwamba kwambiri zomwe zimagwiritsidwa ntchito kwambiri mu ma hydraulic flip plows otchuka (monga Glan, Reken, ndi mitundu ina) ndi ma chisel deep plows omwe ali pamsika. Pamwamba pa chinthucho nthawi zambiri pamakhala utoto wopopera kapena kupewa dzimbiri kuti zigwirizane ndi malo osungira akunja.
