Cov ntaub ntawv siv hauv cov thoob excavator
Koj puas tau xav txog yam khoom siv tau siv rauEXCAVATOR THOOB? Hauv tsab xov xwm no, peb yuav tham txog cov ntaub ntawv feem ntau hauv cov ntawv pins, ob sab, txiav cov vaj tsev, cov hniav ntawm excavator thoob.
Excavator pins
Excavator pins feem ntau yog ua los ntawm Aisi 4130 lossis 4140 hlau. AISI 4000 series steel yog chrome molybdenum hlau. Chromium txhim kho corrosion tsis kam thiab hardening, thaum molybdenum kuj tseem muaj peev xwm muaj zog thiab tsis muaj peev xwm muaj zog.
Thawj tus naj npawb, 4, sawv cev rau qib ntawm cov hlau thiab nws lub ntsiab xo composition (hauv qhov no, chromium thiab molybdenum). Tus lej thib ob 1 sawv cev rau feem pua ntawm cov ntsiab lus, uas txhais tau tias yog 1% chromium thiab molybdenum (los ntawm huab hwm coj). Lub ob tus lej kawg yog cov tshuaj tua kab hauv 0.01% nce ntxiv, yog li Aisi 4130 tau 0.30% roj carbon thiab aisi 4140 muaj 0.40%.
Cov hlau siv tau raug kho nrog induction hardening. Txoj kev kho cua sov no ua rau cov npoo tawv tawv nrog kev hnav tsis kam (58 mus rau 63 Rockwell C) thiab ib sab hauv nruab nrab txhawm rau txhim kho kev nruj. Nco ntsoov tias Bushings feem ntau yog ua los ntawm tib cov khoom uas yog pins. Qee cov neeg ua hauj lwm pheej yig dua yuav tau los ntawm AISI 1045. Nov yog cov hlau siv roj carbon steel uas tuaj yeem ua tsis tau.
Excavator cov thoob ob sab thiab txiav cov npoo
Lub thoob ib sab thiab hniav yog feem ntau yog ua los ntawm ar phaj. Cov chav kawm nrov tshaj plaws yog Ar360 thiab AR400. AR 360 yog nruab nrab carbon tsawg alloy alloy steel uas tau ua cua sov kom muab cov khoom cua sov kom muab cov khoom tiv thaiv zoo thiab muaj peev xwm siab. AR 400 kuj tseem tuaj yeem kho tshav kub, tab sis nws muab cov kev coj tsis kam thiab zoo dua cov txiaj ntsig lub zog. Ob qho tib si steels ua tib zoo ua tib zoo thiab tempered kom ua tiav cov khoom tseem ceeb ntawm lub thoob. Thov nco ntsoov tias tus naj npawb tom qab Ar yog Brinell hardness ntawm cov hlau.
LAWD THOOB plhaub
Thoob tsev yog ib txwm ua los ntawm Astm A572 Qib 50 (qee zaum sau A-572-50), uas yog lub zog siab cov hlau. Cov hlau yog txuam nrog niobium thiab vanadium. Vanadium pab ua kom cov hlau muaj zog. Cov qib qeb ntawm cov hlau yog qhov zoo tagnrho rau cov thoob plhaw vim nws muab lub zog zoo tshaj thaum uas tsawg dua cov hlau sib piv xws li A36. Nws tseem yooj yim rau weld thiab cov duab.
Excavator thoob cov hniav
Txhawm rau sib tham txog dab tsiThoob Cov Hniav Hniavyog ua los ntawm, nws yog ib qho tseem ceeb kom nkag siab tias muaj ob txoj hauv kev ua cov hlau thoob cov hniav: Casting thiab Forging. Cov cam khwb cia thoob cov hniav tuaj yeem ua los ntawm cov tawv ntoo tsawg nrog npib tsib xee thiab molybdenum raws li cov ntsiab lus tseem ceeb. Molybdenum txhim kho lub peev xwm tawv thiab muaj zog ntawm cov hlau thiab tuaj yeem pab txo qee cov ntaub ntawv ntawm pitting corrosion. Npib tsib xee txhim kho lub zog, tawv thiab pab tiv thaiv kom xeb. Lawv kuj tseem tuaj yeem ua los ntawm cov khoom lag luam yas uas tau kho cua sov kom kho tau cov khoom tsis kam thiab muaj zog cuam tshuam. Forged thoob cov hniav kuj tseem ua los ntawm tshav kub ua kom zoo, tab sis hom hlau sib txawv ntawm cov chaw tsim khoom rau cov chaw tsim khoom. Kev kho cua sov txhim kho kev hnav ua tau zoo thiab nce lub zog muaj zog.
Tsa koj cov excavation nrog Bonovo: hwm cov ntaub ntawv thoob
Tshawb nrhiav qhov tsis muaj kev sib txawv ntawm kev ua tau zoo tshaj plaws ntawmBonovo, qhov kev tshaj lij, muaj txiaj ntsig zoo, thiab customization converge kom xa horgan excavator thoob cov ntaub ntawv nrog kev hloov pauv sai. Peb cov thoob excavator tau ua rau cov khoom siv zoo tshaj plaws, ua kom muaj txiaj ntsig zoo rau txhua qhov koj xav tau kev khawb.
Cov khawb av excavator, ua los ntawm kev ua kom muaj zog 4130 lossis 4140 steel, muaj kev zam tshwj xeeb corrosion tsis kam thiab lub peev xwm ua tau zoo. Cov sab thiab txiav cov npoo yog tsim los ntawm AR360 lossis AR400 phaj, muab cov kev hnav zoo tshaj plaws thiab cuam tshuam lub zog. Rau lub thoob cov tsev, peb siv ovtm A572 qib 50 steel, paub rau nws lub zog siab thiab lub teeb yuag. Thaum kawg, peb cov hniav sib tw ua kom zoo nkauj tsim los ntawm kev ua yeeb yam lossis cov txheej txheem forging, ua haujlwm qis qis cov hlau ua kom zoo dua thiab xeb tawm tsam.
Ntawm Bonovo, peb ua ntej tshaj lij cov ntaub ntawv-qib cov khoom siv thiab ua cov kev daws teeb meem, lav qab xa khoom tsis muaj kev cuam tshuam zoo. Xaiv Bonovo rau cov ntaub ntawv txuas ntxiv uas txhawb koj txoj haujlwm tsim kho kom tau qhov siab tshiab.
