Me ntsis kev paub txog thoob cov hniav thiab iav rooj ntawm excavator
Apr 02, 2022
Kev tsim khoom:
Forged thoob hniav: forged thoob hniav feem ntau yog ua los ntawm cov hlau alloy, thiab tom qab ntawd lub tshuab forging yog siv los tso siab rau ntawm cov hlau tshwj xeeb, uas yog extruded thiab tsim nyob rau hauv qhov kub thiab txias, refine cov siv lead ua nyob rau hauv lub forging thiab ua yas. deformation kom tau lub thoob cov hniav nrog cov khoom tshwj xeeb. Yog tias cov hlau tuaj yeem txhim kho nws cov qauv tsim tom qab forging, nws tuaj yeem ua kom ntseeg tau tias lub thoob cov hniav ntawm forged excavator muaj cov khoom siv zoo heev, hnav tsis kam thiab ua haujlwm ntev dua.
Casting thoob hniav: lub thoob cov hniav feem ntau yog ua los ntawm austenitic nodular cam khwb cia hlau, thiab ces cov kua hlau yog cam khwb cia rau hauv lub casting kab noj hniav txuam cov duab ntawm qhov chaw. Tom qab nws txias thiab solidified, qhov chaw los yog blanks yuav tau. Hom kev siv tshuab no tuaj yeem muab kev hnav zoo thiab nkag mus.
Feem ntau, vim cov khoom siv ntawm cov hniav cam khwb cia, nws hnav tsis kam, toughness thiab nkag mus tsis zoo li forged thoob hniav, tab sis nws muaj peev xwm muab sib dua, lub zog zoo dua thiab tus nqi zoo dua.
Yuav ua li cas tuav cov hniav thiab lub rooj zaum iav:
Ua ntej ntawm tag nrho cov, xaiv lub thoob cov hniav yog ib qho tseem ceeb los ua kom lub neej ua hauj lwm thiab muaj zog nkag mus rau koj lub excavator, vim hais tias cov thoob cov hniav thiab cov khoom seem yog qhov yuav tsum tau ua ntej rau kev ua hauj lwm ntawm excavator sai thiab txuag cov ntaub ntawv raw.
Qhov thib ob, thaum lub sij hawm siv cov thoob cov hniav ntawm lub excavator, lub thoob cov hniav sab nraum lub thoob yog 30 feem pua ntau dua li cov khoom puas hauv. Yog li ntawd, tom qab ib lub sij hawm ntawm kev siv, lub thoob cov hniav tuaj yeem hloov mus rau sab hauv thiab sab nraud lossis tig txhua lub sijhawm, uas tuaj yeem txo qis thiab muab cov khoom tsim tau rau qee yam.
Tom qab ntawd, nyob rau hauv cov ntaub ntawv ntawm kev ua hauj lwm tiag tiag ntawm lub excavator, thaum khawb hauv lub thoob cov hniav, lub ntsej muag ua hauj lwm yuav tsum ntsug kom tsis txhob tawg cov thoob cov hniav vim yog inclination ntau dhau.
