Sinjanji yachitsulo imagawidwa kukhala njanji zanjanji, njanji zopepuka, njanji zoyendetsa ndi njanji za crane.Mawonekedwe a njanji amapangidwa ndi gawo looneka ngati I lomwe limapindika bwino kwambiri, mutu wa njanji, chiuno cha njanji ndi pansi pa njanji.
(1) njanji yachitsulo ya njanji
Njanji zachitsulo zotsika za alloy zimapangidwa pamaziko a njanji za carbon.Sitima yapamtunda ya carbon ndi low alloy steel ili ndi mphamvu zambiri, kukana kuvala bwino, kukana kupanikizika, kukana kwa brittle fracture ndi kukana kutopa kwa fracture kuposa njanji ya carbon.Mitundu ya njanji yogwiritsira ntchito njanji ndi 38, 43, 50, 60 ndi 75kg/m, ndi zina zotero. Chisamaliro chapadera chiyenera kuperekedwa kuti tipewe mawanga oyera pakupanga njanji.
(2) Njanji yachitsulo yopepuka
Amagwiritsidwa ntchito kwambiri mumigodi ndi nkhalango, ndipo mitundu yake ndi 5,8,11,15,18 ndi 24 kg/m.Sitima yachitsulo yopepuka imapangidwa makamaka ndi chitsulo cha kaboni, ndipo ochepa amapangidwa ndi chitsulo chochepa cha alloy.Njanji zopepuka zachitsulo zomwe zimagwiritsidwa ntchito m'migodi, pansi pa nthaka ndi nkhalango zimafunikira kukana kwa dzimbiri, motero zinthu zoyenera za alloy monga mkuwa, chromium, phosphorous ndi vanadium zimawonjezeredwa kuchitsulo.
(3) Sitima yachitsulo yoyendetsa
Njanji yachitsulo yomwe imagwiritsidwa ntchito poyendetsa magetsi mu njanji yapansi panthaka imafuna madulidwe abwino, ndiye kuti, resistivity pa 15 ℃ ndi yochepera 0.125 μ ω m.Amapangidwa ndi chitsulo chotsika kwambiri cha carbon aluminium chophedwa.
(4) Njanji yachitsulo ya crane
Kapangidwe kakemidwe ndi kupanga njanji zapadera zachitsulo zomwe zimagwiritsidwa ntchito popanga njanji zosiyanasiyana zowongolera ma crane ndizofanana ndi za njanji zachitsulo.Mitunduyi ndi QU70, QU80, QUl00, QUl20 ndi zina zotero
Ntchito ya njanji yachitsulo ndikuwongolera mawilo ozungulira kuti apite patsogolo, kunyamula kupanikizika kwakukulu kwa mawilo ndikutumiza kwa ogona.Sitima yachitsulo iyenera kukhala yosalekeza, yosalala komanso yocheperako kugudubuza pamwamba pa mawilo.Mugawo la njanji yamagetsi kapena gawo la block block, njanji imatha kugwiritsidwanso ntchito ngati njanji.
Monga China zitsulo makampani kutsogolera mabizinezi, dziko zitsulo malonda ndi katundu "Hundred chikhulupiriro chabwino ogwira ntchito", China zitsulo malonda mabizinezi, "Top 100 mabizinezi wamba ku Shanghai". ) imatenga "Kukhulupirika, Kuchita, Kupanga Zinthu, Win-Win" monga mfundo yake yokhayo yogwiritsira ntchito, nthawi zonse amalimbikira kuika zofuna za makasitomala poyamba.
