Muaj ntau hom pa luam yeeb dub los ntawm lub cav, xws li: ①Lub tshuab muaj cov pa luam yeeb dub hauv ib qho kev ua. Nws tsuas haus luam yeeb xwb. ③Txhua yam zoo li qub thaum lub tshuab ua haujlwm siab ua haujlwm, tab sis nws tsis ua haujlwm. Thaum nres tsheb, lub tsheb ceev yuav tawm cov pa taws dub, thiab nws zoo li lub tsheb rov qab. ④320c tsis muaj intercooler, thiab 5-8 iav yog tawm Ceev yog hais txog 250, lub thoob khib nyiab yog tag nrho cov pa luam yeeb dub, roj kub thiab dej kub tsis siab. Lub tank diesel raug ntxuav, cov kab hluav taws xob hloov pauv, cov yeeb nkab diesel raug hloov, lim cua hloov, lub twj tso kua mis diesel, lub nozzle raug kho, lub voj voog yog qhov qub, thiab cov hydraulic ntws yog tig, cov pa taws dub. tseem tshuav, lub cav tso cov yeeb nkab tsis muaj cua, qhov kev ua haujlwm hydraulic yog tag, thiab qhov ceev yog qis dua, thiab cov pa luam yeeb dub kuj tseem me dua.
Ntawm qhov chaw tsim kho, peb feem ntau pom cov pa luam yeeb dub los ntawm excavators. Txhua tus neeg kuj paub tias qhov tseem ceeb ntawm cov pa luam yeeb dub los ntawm lub cav yog qhov tsis txaus combustion. Yog vim li cas yog roughly muab faib rau hauv cov huab cua tsis zoo, hydraulic twj tso kua mis zog tshaj lub cav, thiab lub cav. Nws tus kheej malfunctions, thiab lwm yam.
Nws tsis txaus kom paub tias yog vim li cas, peb yuav tsum nrhiav kev daws teeb meem zoo tshaj plaws, vim tias cov pa luam yeeb dub los ntawm excavator zoo li yog ib qho teeb meem me me, tab sis yog tias nws tsis daws raws sijhawm, nws yuav ua rau lub excavator hlawv roj thiab txawm ua rau lub cav puas thiab overhauled.
Qhov tshwm sim ua tsis tiav
1. Cov pa luam yeeb dub tshwm sim los ntawm huab cua tsis txaus lossis cov dej xau ntawm cov kav dej. Vim yog siv lub sijhawm ntev ntawm lub excavator, kev laus thiab kev puas tsuaj ntawm cov kav dej thiab cov yeeb nkab clamp yuav ua rau cov yeeb nkab xau, nqus plua plav loj, thiab thaiv cov cua txias, thiab lwm yam, uas yuav ua rau cov pa taws dub tshwm sim. . Yog tias qhov teeb meem zoo li no tshwm sim, nws yuav tsum tau daws raws sij hawm, txwv tsis pub lub cav yuav muaj kev cuam tshuam thaum ntxov, lossis txawm tias rub lub tog raj kheej thiab lwm yam tsis ua haujlwm.
2. Yog tias lub cav tso pa tawm ntau cov pa luam yeeb dub thiab lub zog poob qis heev, nws yuav tsum tau kuaj xyuas seb puas muaj cov roj to hauv cov kav dej ntawm lub turbocharger, lub turbine log ntawm lub turbocharger, thiab seb cov hniav puas lawm. , hnav, los yog deformed. , Seb puas muaj khawb puas nyob rau hauv lub turbocharger vaj tse, thiab seb lub impeller ncej clearance tshaj 3 hli.
Yog tias cov xwm txheej no tshwm sim, lub turbocharger yuav tsum tau hloov.
3. Tshawb xyuas seb lub twj tso kua mis diesel thiab roj injector puas hnav thiab tshwm sim los ntawm cov pa luam yeeb dub. Lub excavator tseem muaj zog thaum lub cav tso pa taws dub, tab sis lub cav ceev yuav poob (tshaj 200 rpm).
Qhov tshwm sim no feem ntau yog vim qhov tsis ua haujlwm ntawm lub tshuab hluav taws xob diesel (lub tog raj kheej-tawg sim tuaj yeem siv los kuaj xyuas qhov zoo ntawm cov injector). Yog hais tias lub excavator feem ntau tawm cov pa luam yeeb dub thiab nws tsis yooj yim rau pib, nws yuav tsum tau ntim nrog oob khab. kua.Qhov tshwm sim no yuav tsum tau kuaj xyuas lub twj tso kua mis diesel.
4. Yog hais tias lub cav EGR valve puas los yog daig, nws tseem yuav ua rau cov pa luam yeeb dub. Yog tias EGR valve tsis ua haujlwm, lub tswb yuav tshwm rau ntawm cov zaub. Yog tias qhov txhaum tshwm sim, nws yuav tsum tau hloov lub sijhawm, txwv tsis pub nws yuav cuam tshuam rau kev ua haujlwm ntawm lub cav, thiab nws tuaj yeem pom tseeb tias nws siv roj ntau dua li kev ua haujlwm ib txwm muaj.
5. Lub excavator tsis muaj zog thaum lub cav emissions dub pa luam yeeb, thiab muaj kev hloov ntawm lub suab thaum lub cav ua hauj lwm nyob rau hauv load. Lub sijhawm no, nws zoo li lub zog ntawm lub twj tso kua mis hydraulic tshaj lub zog ntawm lub cav ua rau cov pa luam yeeb dub. Lub sijhawm no, ua ntej txo qhov ntws thiab siab ntawm lub twj tso kua mis hydraulic.Yog tias qhov txhaum tseem tshwm sim tom qab lub twj tso kua mis hydraulic hloov mus rau tus nqi ib txwm, ces lub cav roj yuav tsum tau kuaj xyuas.Yog tias qhov ntws thiab siab ntawm lub twj hydraulic tsis tuaj yeem. raug txo qis, ces cov khoom siv hydraulic yuav tsum tau kuaj xyuas.
Cov ntsiab lus ntawm cov pa luam yeeb dub tsis ua haujlwm ntawm lub cav excavator:
Txawm hais tias qhov tshwm sim ntawm cov pa luam yeeb dub los ntawm lub cav yog qhov nyuaj heev, hauv kev txheeb xyuas zaum kawg, cov laj thawj rau qhov tsis ua haujlwm yog cov no. Thaum kuaj xyuas thiab tuav, koj yuav tsum ua tib zoo saib xyuas qhov tshwm sim tsis ua haujlwm txhawm rau ua qhov kev txiav txim siab tshaj plaws.
Yog tias koj xav tau cov khoom siv cuam tshuam lossis cov excavator tshiab (XCMG excavator, SANY excavator, KOMATSU excavator, thiab lwm yam), koj tuaj yeem tiv tauj peb!
