Malo olima, gawo la pulawo, zida za pulawo zaulimi, zida za makina a pafamu, nsonga ya pulawo yosatha, zida zolima

Kufotokozera Kwachidule:

Iyi ndi pulawo (gawo la pulawo)—gawo lolimba lomwe silingawonongeke ndi mapulawo a ulimi ndi zida zolima. Yopangidwa ndi chitsulo champhamvu kwambiri, chosawonongeka ndi chitsulo cha alloy, ili ndi nsonga yakuthwa komanso yolimba kuti nthaka ilowe bwino komanso ikule bwino. Yopangidwa kuti igwiritsidwe ntchito molimbika, imatsimikizira kuti ikulima bwino, imachepetsa kukana kwa nthaka, komanso imawonjezera nthawi yogwira ntchito ya zida zolima.

Tumizani imelo kwa ife

Tsatanetsatane wa Zamalonda

Ma tag a Zamalonda

• Amagwiritsidwa ntchito pa mapulawu, matila, ndi makina okonzera nthaka

• Imalowa ndi kutembenuza nthaka yobzala ndi kulima

• Amachepetsa kukangana ndi kuwonongeka panthawi yolima

• Chofunika kwambiri pakukonza bwino kulima ndi ubwino wa nthaka

Chogulitsachi chapangidwa makamaka kuti chigwiritsidwe ntchito polima ulimi wamakono. Monga chinthu chofunikira, chomwe chimawonongeka mosavuta chomwe chimakhudzana mwachindunji ndi nthaka ndipo chimapirira kukangana kwakukulu ndi kugundana, nsonga ya pulawo imapangidwa ndi chitsulo chapamwamba kwambiri. Ndi yoyenera kugwiritsidwa ntchito ndi zida zosiyanasiyana zolima monga mapulawo a moldboard, mapulawo osinthika, ndi ma ditcher, ndipo ndi gawo lothandizira kwambiri pakukweza magwiridwe antchito a makina onse, kuchepetsa kugwiritsa ntchito mphamvu, ndikuwonetsetsa kuti ulimi uli bwino.

Mosiyana ndi zinthu wamba zotayidwa, timagwiritsa ntchito njira yolondola yopangira zinthu kuti tichotse ma porosity amkati ndi mabowo amchenga, zomwe zimapangitsa kuti kukhuthala kwa zinthuzo kukhale kolimba komanso kolimba. Chitsulocho chimapangidwa mwasayansi ndi zinthu za chromium (Cr) ndi boron (B), ndipo chimatenthedwanso pamalo ofunikira. Izi zimatsimikizira kuuma kwa pamwamba pa 48-52 HRC pamene zikusunga kusinthasintha kwabwino kwa pakati, zomwe zimathandiza kuti ming'alu isagwere miyala kapena mizu ya mitengo panthawi yogwira ntchito.

Yosawonongeka kwambiri: Kudzera mu tungsten carbide coating yokhuthala kapena ukadaulo wolimba wa alloy, moyo wa ntchito m'nthaka yolimba monga mchenga ndi miyala umakulitsidwa kwambiri. Miyeso yeniyeni imasonyeza moyo wa pulawo wa nthawi 3-5 kuposa wa pulawo wamba wachitsulo.

Kulowa kwa nthaka movutikira: Kugwiritsa ntchito kapangidwe kake kozungulira, kogwirizana ndi nthaka komanso kukana kuyenda kumachepa, zomwe zimapangitsa kuti kugwiritsa ntchito mafuta mu thirakitala kuchepe ndi pafupifupi 8%-12%.

Kudzinola kotetezeka: Kapangidwe kake kapadera kamalola nsonga ya pulawo kukhala ndi m'mphepete wakuthwa panthawi yopasuka, kupewa mavuto monga kulima kosakwanira komanso kuphimba kosakwanira komwe kumachitika chifukwa cha kufooka.
