Cov Khoom Taw Qhia thiab Siv

40crnimoa raug xa mus rau cov hlau hluavtaws hlau, 40cnimoa yog ib qho ntawm cov hlau hluavtaws, tseem muaj feem cuam tshuam ntawm cov hlau muaj zog, tag nrho cov ntsiab lus ntawm tsis ntau tshaj 5%) thiab ua los ntawm cov hlau. Cov kabmob hauv qhov chaw tom qab kev kho cua sov ua kom zoo tsis xws luag

Siv rau qhov yuav tsum muaj ntawm lub zog siab, siab tawv, tseem ceeb tshaj plaws feling tshuab dring eccentric ncej, forging xovxwm crankshaft. Siv tom qab tempering, rau kev ua cov chaw tseem ceeb uas xav tau zoo, siab lub zog thiab loj loj. Yog tias cov tshuab hnyav hauv cov tshuab hluav taws xob siab, lub taub ntau dua 250 hli ntau dua 250 hli tshuab, siab, crankshafts, zog thiab lwm yam. Ib qho ntxiv, tseem tuaj yeem yog Nitrivoniding kev kho mob siv los ua qhov kev xav tau tshwj xeeb ntawm cov khoom tseem ceeb.
