Nsonga ya pulawo yolimba kwambiri yosatha, zowonjezera za makina a ulimi

Kufotokozera Kwachidule:

【Chida Chothira Mozama - Mutu Wakuthwa wa Pula】Chopangidwa makamaka kuti chigwiritse ntchito pokonzanso nthaka yolimba, chopangidwa ndi chitsulo champhamvu kwambiri, sichimawonongeka komanso sichimakhudzidwa ndi kugunda. Malo opindika osalala amatsimikizira kuti nthaka imasweka bwino ndipo amachepetsa kwambiri kukana kugwira ntchito. Masamba owongoka bwino amalola kuti nthaka ilowe mwachangu komanso kuti nthaka ikhale yolimba, ndikutembenuza bwino zigawo za nthaka. Chogwirizana ndi mitundu yayikulu, chosavuta kuyika, ndi mnzake wodalirika pakukweza magwiridwe antchito ndikuwonetsetsa kuti ulimi wozama umakhala wabwino.

Nsonga ya pulawo ndi gawo lofunika kwambiri pa ulimi wamakono wolondola. Yopangidwa pogwiritsa ntchito zipangizo zamakono komanso njira zamakono, yapangidwa makamaka kuti igwire ntchito zosiyanasiyana zovuta za nthaka. Chifukwa cha kukana kwake kuwonongeka kosayerekezeka, kugwiritsa ntchito bwino nthaka, komanso kulimba, imachepetsa kwambiri kukana kulima ndi kugwiritsa ntchito mafuta, zomwe zimapangitsa kuti ikhale chisankho chanzeru chowongolera magwiridwe antchito, kuonetsetsa kuti kulima bwino, komanso kupanga phindu kwa ogwiritsa ntchito kwa nthawi yayitali.

1、Zatsopano pa Zida: Chitsulo chapadera cha alloy (monga 65Mn, 60Si2Mn) kapena chitsulo champhamvu cha boron chimagwiritsidwa ntchito, ndipo kudzera mu njira yolondola yochizira kutentha (kuzimitsa + kutentha), kuuma kwakukulu (HRC kumatha kufika pa 50) kumapangidwa pamphepete mwachitsulo, pomwe kumasunga kulimba kwabwino kwa thupi la nsonga ya pulawo, zomwe zimapangitsa kuti likhale lolimba komanso losasweka mosavuta.

Ukadaulo Wowonjezereka: Ndodo zolumikizira zokhazikika zomwe sizingawonongeke kapena zomangira zolimba za tungsten carbide zitha kugwiritsidwa ntchito kupanga gawo loteteza kwambiri m'malo osavuta kusweka, ndikuwonjezera nthawi yogwira ntchito ndi nthawi 2-3 poyerekeza ndi zomangira wamba.

1、Kapangidwe ka malo opindika bwino: Kutsatira mfundo za kayendetsedwe ka nthaka, kuonetsetsa kuti nthaka imalowa mwachangu komanso nthaka ikusweka bwino, kuchepetsa kukana kulima ndi 15%-25%, komanso kusunga mphamvu ndi mafuta a thirakitala kwambiri.

2、Kapangidwe ka tsamba lodzinola lokha: Limasunga tsamba lakuthwa loti ligwire ntchito nthawi yogwiritsidwa ntchito, kuonetsetsa kuti nthaka yake ndi yolimba komanso nthaka yake imazungulira bwino nthawi yonse ya moyo wake.
