Cov txheej txheem tsim khoom
Forgedcov hniav thoob:Cov hniav thoob forged feem ntau yog ua los ntawm cov hlau sib xyaw, thiab tom qab ntawd lub tshuab forging siv los siv lub zog rau cov hlau tshwj xeeb, thiab tom qab ntawd extruded ntawm qhov kub siab los ua kom cov khoom siv siv lead ua hauv kev forging los tsim cov yas deformation kom tau txais qee yam khoom siv kho tshuab. Tom qab forging, cov hlau tuaj yeem txhim kho nws cov qauv, uas tuaj yeem ua kom ntseeg tau tias cov hniav thoob forged muaj cov khoom siv kho tshuab zoo, tiv taus hnav ntau dua, thiab muaj lub neej ua haujlwm ntev dua.
Kev ua yeeb yamcov hniav thoob:Feem ntau, cov hlau graphite spheroidal Austenitic siv rau kev ua cov hniav thoob, thiab tom qab ntawd cov hlau ua kua raug pov rau hauv qhov chaw ua kom haum rau cov duab ntawm qhov khoom. Tom qab nws txias thiab khov, qhov khoom lossis daim ntawv dawb paug tau txais. Cov txheej txheem no tuaj yeem muab kev tiv thaiv zoo thiab nkag mus.
Feem ntau, vim yog cov qauv khoom siv ntawm cov hniav cam khwb cia, nws txoj kev tiv thaiv kev hnav, kev tawv thiab kev nkag mus tsis zoo li cov hniav forged, tab sis nws tuaj yeem muab qhov hnyav sib dua, qhov nyuaj zoo dua thiab tus nqi pheej yig dua.
Yuav ua li cas thiaj tswj taucov hniav thoobthiab cov rooj zaum hniav
Ua ntej tshaj plaws, kev xaiv cov hniav thoob zoo yog qhov tseem ceeb hauv kev ua kom koj lub excavator lub neej ua haujlwm ntev dua thiab muaj zog nkag mus tob dua, vim tias cov hniav thoob sib phim thiab cov khoom siv yog qhov yuav tsum tau ua rau lub voj voog ua haujlwm ntawm lub excavator sai dua thiab txuag cov khoom siv raw.
Qhov thib ob, thaum lub sijhawm siv cov hniav thoob ntawm lub tshuab khawb av, cov hniav sab nraud ntawm lub thoob yog 30% sai dua li qhov hnav sab hauv tshaj plaws. Yog li ntawd, tom qab ib lub sijhawm, koj tuaj yeem hloov qhov chaw ntawm sab hauv thiab sab nraud ntawm lub thoob lossis tig nws mus rau qee qhov. Txhawm rau kom yooj yim thiab muab kev tsim khoom.
Tom qab ntawd, thaum ua haujlwm rau lub tshuab khawb av, nws yog qhov zoo tshaj plaws kom khawb hauv qab cov hniav thoob uas sib dhos rau qhov chaw ua haujlwm kom tsis txhob tawg cov hniav thoob vim muaj kev cuam tshuam ntau dhau.
Thaum kawg, txheej tungsten coatings rau ntawm cov hniav thoob thiab lwm yam khoom siv tuaj yeem txo cov nqi txij nkawm thiab txhim kho kev ua haujlwm ntawm lub tshuab.
Yog tias nws yog los hloov lub thoob, uashniav thoobzoo dua?
Qhov no yuav cuam tshuam txog hom excavator koj yog thiab qhov chaw twg koj feem ntau siv.
1 Cov hniav thoob dav dav, cov khoom tawv, qhov nyuaj nruab nrab, cov xwm txheej ua haujlwm dav dav
2 Cov hniav thoob rau cov zaub mov Muaj zog heev thiab muaj zog cuam tshuam nruab nrab Siv rau cov xwm txheej cuam tshuam hnyav
3 Cov hniav thoob tshwj xeeb, qhov nyuaj siab, qhov cuam tshuam loj heev, siv rau cov xwm txheej ua haujlwm nrog kev hnav thiab cuam tshuam hnyav
