Tsamba lolimba la pulawo lachitsulo cha manganese, chowonjezera chosafota cha kulima Chithunzi Chowonetsedwa

Tsamba lolimba la pulawo lachitsulo cha manganese, chowonjezera cholima chosafota

Kufotokozera Kwachidule:

Tsamba la pulawo, lomwe ndi gawo lothandizira pa makina a ulimi, limapangidwa ndi chitsulo champhamvu kwambiri komanso chosatha. Mphepete mwake mwapadera mumalandira chithandizo chapadera cha kutentha, zomwe zimapangitsa kuti nthaka ikhale yolimba komanso yolimba. Yopangidwa kuti igwirizane ndi makina osiyanasiyana olima, ndi yosavuta kuyiyika. Imadula nthaka bwino, imatembenuza udzu pamwamba ndi ziputu, zomwe zimapangitsa kuti ulimi ugwire bwino ntchito komanso kuti ukhale wolimba, zomwe zimapangitsa kuti ukhale wolimba kwambiri poonetsetsa kuti ntchito zaulimi zikuyenda bwino.

Chogulitsachi ndi pulawo, gawo logwiritsidwa ntchito popanga makina a zaulimi, makamaka lopangidwira mapulawo a bolodi, mapulawo osinthika, ndi mapulawo ozama. Monga gawo lofunika kwambiri lomwe limakhudza nthaka mwachindunji ndikupirira kukangana kwakukulu ndi kugundana, ubwino wake umakhudza mwachindunji magwiridwe antchito a kulima, mtengo wamafuta, komanso kukhazikika kwa ntchito. Pulawo iyi ili ndi kapangidwe kabwino kwambiri ndipo imapangidwa ndi zipangizo zolimba kwambiri, zomwe zimapangitsa kuti ikhale yoyenera malo ouma, nthaka yolimba, komanso malo olima omwe ali ndi mchenga wochepa kapena wochepa.

Zipangizo zoyambira: Chitsulo cha masika cha 65Mn kapena mbale ya boron ya 30MnB5 boron yozunguliridwa ndi moto, yotenthedwa bwino. Mtundu wa 65Mn uli ndi mphamvu yabwino kwambiri yobwezeretsa kusinthika kwa elastic ndipo ndi yoyenera nthaka ya mchenga yokhala ndi mphamvu yochepa; mtundu wa 30MnB5, kudzera mu njira yozimitsa + kutentha pang'ono, ukhoza kukhala ndi kuuma kwa pamwamba kwa 38-42 HRC, pomwe ukusunga kulimba pakati kuti usagwe chifukwa cha miyala.

Kupewa dzimbiri pamwamba: Kuchotsa mdima wakuda kapena mankhwala a Dacromet, zomwe zimapangitsa kuti dzimbiri lisawonongeke panthawi yosungira komanso nthawi yochepa yoyika m'munda.

Kulimbitsa kosatha: Malo ogwirira ntchito (nsonga ya fosholo ndi m'mphepete mwachitsulo) amatha kupopedwa ndi wosanjikiza wa alloy wosatha kapena plasma welded. Kulimba kwa wosanjikiza wa weld ndi ≥58 HRC, ndipo nthawi yogwira ntchito imawonjezeka ndi oposa 40% poyerekeza ndi mapulawo wamba a 65Mn pansi pa mikhalidwe yofanana yotha.

Malo Olumikizirana ndi Dothi: Malo opindika a thupi la fosholo amakonzedwa bwino kutengera momwe nthaka imagwirira ntchito, amachepetsa kukana kulowa kwa nthaka ndi 12%-15%, kuonetsetsa kuti nthaka imachotsedwa bwino ndikuchepetsa kuchuluka kwa dothi.

Kulimbitsa Nthiti ndi Mabowo a Bolt: Nthiti yolimbitsa ya trapezoidal imawonjezedwa kumbuyo, zomwe zimawonjezera mphamvu yopindika ndi 30%; mabowo a bolt ali ndi kapangidwe ka countersunk, kogwirizana ndi mabowo a M12/M14 amphamvu kwambiri, kuonetsetsa kuti ikugwirizana bwino ndi pulawo ndi mbale zam'mbali, kuteteza kumasuka ndi kusweka.

Kapangidwe ka Nsonga ya Fosholo Yosinthika (Mwasankha): Mitundu ina imagwiritsa ntchito nsonga ya fosholo yokhazikika ndi bolt yogawanika; nsonga yokhayo imafunika kusinthidwa ikawonongeka, zomwe zimachepetsa ndalama zokonzera.

Kugwiritsa ntchito mafuta ochepa: Ngodya yodulira bwino pamodzi ndi masamba osatha ntchito zimapangitsa kuti mafuta asagwire bwino ntchito, zomwe zimapangitsa kuti mafuta asamawonongeke ndi 8%-10%.

Kudalirika Kwambiri: Pambuyo pa maola 500 a kuyesa kowononga munda, palibe kusweka kapena kugwedezeka kwa tsamba komwe kunawonedwa, zomwe zinakwaniritsa zosowa za kulima malo opitilira 3000 mu (pafupifupi mahekitala 200) pa nyengo iliyonse.

Kusintha mwachangu: Kutalikirana kwa mabowo a bolt kumagwirizana ndi mapulawu otchuka ochokera kunja ndi akunyumba (monga Recon, Gran, ndi Gaomidelon), osafuna kusintha chimango.
