Lub thoob cov hniav ntawm excavator yog ib qho ntawm cov khoom tseem ceeb ntawm lub excavator, Zoo ib yam li tib neeg cov hniav, nws yog tsim los ntawm cov hniav thiab adapters, uas txuas nrog tus pin thiab retainer.Vim qhov hnav thiab tsim kua muag ntawm lub thoob, cov hniav yog qhov tsis raug, tsuav yog cov hniav hloov.

1, Cov qauv thiab kev ua haujlwm ntawm cov hniav thoob
Raws li lub thoob hniav puag.Feem ntau, muaj ob hom thoob cov hniav ntawm excavators, uas yog ncaj mounted thiab transverse mounted.Vertical installation txhais tau hais tias tus pin ncej yog vertically ntsia nrog lub ntsej muag pem hauv ntej ntawm lub thoob khib nyiab hniav;hom kab rov tav installation yog hais txog kev sib txuas ntawm tus pin ncej thiab lub ntsej muag pem hauv ntej ntawm cov hniav khawb thoob.
(Vertical installation / kab rov tav)

Vertical installation hom: nws yooj yim rau disassemble thiab nruab ncaj qha los ntawm saum toj no nrog rau qhov chaw ua haujlwm loj.Thaum lub sij hawm excavation, tus hniav pin ntsia ncaj qha yuav raug rau lub extrusion siab ntawm cov khoom excavated.Yog tias lub zog khawb loj, lub zog clamping ntawm lub caij nplooj ntoo hlav tuaj yeem ua tsis tau raws li qhov yuav tsum tau ua, uas yuav yooj yim ua rau tus hniav pin ntog.

Yog li ntawd, Vertical installation hom feem ntau yog siv nyob rau hauv excavators nrog me me excavators thiab qis tonnage.

Kab rov tav mounting hom: nws tsis yooj yim rau disassemble, qhov chaw ua haujlwm sab me me, lub zog nyuaj dua, thaum disassembling ib lub thoob cov hniav, nws yuav tsum tau disassembled thiaj li siv cov cuab yeej tshwj xeeb ntev ntev.Nyob rau hauv lub excavation, pem hauv ntej ntawm lub transverse iav pin yuav tsis raug rau lub extrusion siab ntawm excavated khoom, thiab muaj peev xwm tiv taus lub excavation quab yuam, tab sis lub caij nplooj ntoos hlav o nyob rau hauv kev siv ntawm reciprocating lateral quab yuam, yooj yim hnav, tsis ua hauj lwm, ua rau. hauv tus hniav pin poob.

Yog li cov kab rov tav installation feem ntau yog siv nyob rau hauv lub excavation quab yuam ntawm ntau tshaj 20 tons ntawm excavator.

Raws li kev siv excavator thoob cov hniav ib puag ncig kev faib tawm.Excavator thoob cov hniav tuaj yeem muab faib ua cov hniav pob zeb (rau hlau ore, pob zeb, thiab lwm yam), cov hniav hauv av (rau khawb av, xuab zeb, thiab lwm yam), cov hniav conical (rau cov mines).Tab sis cov duab ntawm thoob hniav ntawm txawv hom excavator kuj muaj nws tus yam ntxwv.

(Pob zeb hniav / ntiaj teb hniav / cone hniav)

Vim li cas excavators nruab thoob cov hniav?Nrog ntau lub thoob cov hniav, peb tuaj yeem pom:

1. Tiv thaiv tag nrho lub thoob.Lub thoob cov hniav yog cov khoom hnav, vim tias lub thoob hauv kev ua haujlwm ntawm kev hnav, ua ke nrog cov thoob cov hniav, rau qee yam los tiv thaiv lub thoob.

2. Ua kom qhov kev ua haujlwm ntau dua.Rau kev ua haujlwm me me, nws tsis tuaj yeem ua tiav yam tsis muaj cov hniav thoob.

3. Yooj yim rau khawb thiab duav.Lub thoob cov hniav yog conical, thoob cov hniav thiab cov hniav nyob nruab nrab ntawm yog ib tug dawb paug, yog li ntawd lub zog ntawm tag nrho cov thoob, acting nto yog me me, siab yuav nce, kev ua hauj lwm yuav du.

4. Nws tuaj yeem cuam tshuam tag nrho lub tshuab tom qab khawb cov khoom nyuaj.

2 、 Kev yuav cov hniav thoob
Feem ntau, muaj qhov sib txawv ntawm cov cam khwb cia thiab forged thoob hniav.Feem ntau, forged thoob hniav yog hnav-resistant thiab muaj zog dua.Lub neej kev pab cuam ntawm forged thoob cov hniav yog hais txog 2 npaug ntawm casting thoob hniav, thiab tus nqi yog hais txog 1.5 npaug ntawm casting thoob hniav.
Casting thoob hniav: casting kua hlau mus rau hauv lub casting kab noj hniav sib haum mus rau cov duab ntawm ib feem, thiab ces txias thiab solidifying cov kua hlau kom tau qhov chaw los yog dawb paug yog hu ua casting.Mechanical zog, hnav tsis kam thiab kev pab cuam lub neej ntawm castings yog qis dua cov forgings.
Forging thoob cov hniav: cov tshuab forging yog siv los ua kom lub siab ntawm cov hlau tshwj xeeb, uas yog extruded ntawm qhov kub thiab txias los ua kom cov khoom siv lead ua kom zoo nyob rau hauv forging los tsim cov yas deformation kom tau txais qee yam khoom siv.Tom qab forging, cov qauv ntawm cov hlau tuaj yeem txhim kho, uas tuaj yeem xyuas kom meej tias cov hniav txhuam hniav muaj cov khoom siv zoo, hnav tsis kam thiab ua haujlwm ntev dua.
Tau kawg, thaum yuav cov hniav thoob, peb kuj yuav tsum tau saib seb lub thoob cov hniav zoo li cas tus excavator siv nyob rau hauv txhua qhov chaw ua haujlwm.
General excavation, xoob xuab zeb, thiab lwm yam. siv cov thoob cov hniav.Qhov thib ob, RC hom thoob cov hniav yog siv rau kev khawb cov pob zeb loj heev, thiab TL hom thoob cov hniav feem ntau yog siv los khawb cov pob zeb loj heev.
Tsis tas li ntawd, hauv cov txheej txheem ua haujlwm tiag tiag, cov neeg feem coob nyiam cov hniav RC thoob.Tus kws kho me me qhia tias RC hom thoob cov hniav yuav tsum tsis txhob siv feem ntau, thiab lub qhov ncauj tiaj tus thoob cov hniav yuav tsum tau siv zoo dua, vim tias tom qab RC thoob cov hniav tau hnav rau lub sijhawm, kev khawb kuj nce ntxiv thiab lub zog. yog nkim, thaum lub qhov ncauj tiaj tus thoob cov hniav ib txwm tuav lub ntsej muag ntse nyob rau hauv cov txheej txheem hnav, thiaj li yuav txo tau qhov khawb tsis kam thiab txuag roj.

3, thoob cov hniav tu thiab ncua lub neej kev pab cuam ntawm lub tswv yim

1. Nyob rau hauv tus txheej txheem ntawm kev siv lub thoob cov hniav ntawm lub excavator, lub thoob thoob cov hniav yog 30% sai dua cov innermost hnav.Tom qab ib ntus, cov hniav sab hauv thiab sab nraud tuaj yeem hloov pauv.
2. Thaum lub sijhawm ua haujlwm, tus neeg tsav tsheb ntawm excavator yuav tsum yog perpendicular mus rau lub ntsej muag ua haujlwm thaum khawb hauv qab lub thoob cov hniav kom tsis txhob tawg cov thoob cov hniav vim yog inclination ntau dhau lub kaum sab xis.
3. Tsis txhob viav vias lub excavator caj npab los ntawm ib sab mus rau sab nyob rau hauv cov ntaub ntawv ntawm kuj zoo kawg thiab kuj, raws li nws yog ib qho yooj yim rau fracture lub thoob cov hniav thiab cov hniav hauv paus vim muaj zog ntau dhau ntawm sab laug thiab sab xis, tsis xav txog lub zog tsim ntawm lub sab laug thiab sab xis.
4 Thaum cov hniav hauv paus hnav tawm 10% tom qab kev pom zoo los hloov cov hniav hauv paus, hnav cov hniav loj dhau thiab cov hniav thoob muaj qhov sib txawv loj, kom cov hniav thoob thiab cov hniav sib koom ua ke, thiab cov ntsiab lus quab yuam tau hloov, thoob cov hniav. vim qhov kev hloov ntawm lub zog taw tes thiab tawg.
