Cov qauv excavator feem ntau suav nrog chav tsev fais fab, chav ua haujlwm, slewing mechanism, tswj mechanism, kis mechanism, taug kev mechanism thiab cov chaw pabcuam.
Lub tshuab xa hluav taws xob xa tawm lub zog ntawm lub cav mus rau hydraulic motors, hydraulic thooj voos kheej kheej thiab lwm yam actuators los ntawm lub twj tso kua mis hydraulic, thiab thawb cov cuab yeej ua haujlwm kom txav mus los, yog li ua tiav ntau yam dej num.
Taug kev ntaus ntawv
Cov cuab yeej taug kev yog lub chassis, suav nrog tus ncej crawler thiab txoj kev taug kev. Nws yog tsim los ntawm cov crawler thav duab, taug kev lub cev muaj zog + reducer thiab nws cov raj xa dej, lub log tsav, lub log qhia, lub log txhawb nqa, lub log txhawb nqa, lub crawler, thiab cov khoom siv tsis sib haum. Lub luag haujlwm yog txhawb nqa qhov hnyav ntawm lub excavator thiab hloov lub zog xa mus los ntawm kev tsav lub log rau hauv traction kom paub txog kev taug kev ntawm tag nrho lub tshuab.
Lub thav duab sib dhos (piv txwv li, crawler taug kev thav duab sib dhos) yog ib qho tseem ceeb welded ib feem nrog X-zoo li tus qauv. Nws lub ntsiab kom zoo dua yog nws cov load siab -cov kabmob muaj peev xwm. Lub thav duab sib dhos yog welded los ntawm peb qhov chaw: sab laug longitudinal beam (uas yog, sab laug crawler thav duab), lub ntsiab ncej (uas yog, nruab nrab ncej), thiab txoj cai longitudinal beam (uas yog, txoj cai crawler thav duab). Qhov hnyav ntawm lub rooj sib txoos yog 2 tons.
Lub hauv paus swivel sib koom ua ke yog cov khoom siv hydraulic uas txuas lub slewing platform thiab roj Circuit Court ntawm lub chassis. Nws ua kom ntseeg tau tias lub cev muaj zog taug kev tseem tuaj yeem faib cov roj ib txwm tom qab lub slewing platform tig ntawm txhua lub kaum sab xis. Tam sim no kev sib koom ua ke yog 5-txoj kev [4].
khoom siv ua haujlwm
Cov cuab yeej ua haujlwm yog qhov tseem ceeb ntawm hydraulic excavator. Tam sim no, SY series excavator yog nruab nrog lub tshuab ua haujlwm backhoe. Nws yog tsuas yog siv los khawb av hauv qab qhov chaw nres tsheb, tab sis nws tseem tuaj yeem khawb cov av hauv qab qhov siab tshaj plaws txiav qhov siab, tsuas yog khawb. , ditching thiab chaw thau khoom kuj tuaj yeem ua haujlwm yooj yim ntawm qhov chaw ua haujlwm. Excavation ua hauj lwm yog tsim rau excavating cov av ntawm qib Ⅰ ~ Ⅳ, thiab saum toj no qib Ⅴ, hydraulic rauj los yog blasting txhais tau tias yuav tsum tau.
Lub backhoe ua hauj lwm ntaus ntawv yog tsim los ntawm cov khoom tseem ceeb xws li boom, stick, thoob, rocker, txuas pas nrig, thiab ua hauj lwm ntaus ntawv hydraulic pipeline xws li boom cylinder, stick cylinder thiab thoob cylinder.
Fais fab kis txoj kab lus
1. Kev mus ncig lub zog kis tau tus mob: lub cav diesel-coupling- hydraulic twj tso kua mis (lub zog siv hluav taws xob hloov mus rau hydraulic zog)- faib valve-central swivel sib koom ua ke- lub cev muaj zog (hydraulic zog hloov mus rau hauv lub zog siv hluav taws xob)- txo cov iav lub thawv{--Track-Track
2. Rotary motion transmission route: diesel engine-coupling-hydraulic pump (mechanical energy is converted into hydraulic zog)-distribution valve-slewing motor (hydraulic zog hloov dua siab tshiab rau hauv txhua yam zog)- txo iav kem-slewing} nplhaib kom ua tiav {{7}
3. Boom zog kis tau tus mob txoj kev: Diesel cav-coupling- hydraulic twj tso kua mis (lub zog tshuab yog hloov mus rau hydraulic zog)- faib valve-boom lub tog raj kheej (hydraulic zog yog hloov dua siab tshiab rau hauv txhua yam zog)- paub boom zog
4. Txoj kev txav mus los ntawm txoj kev: lub cav diesel-coupling- lub twj tso kua mis hydraulic (lub zog siv hluav taws xob hloov mus rau lub zog hydraulic)- faib valve- lub tog raj kheej nplaum (lub zog hydraulic hloov mus rau hauv lub zog txhua yam)- kom ua tiav cov pas nrig
5. Lub thoob txav txoj kev xa mus: Diesel cav-coupling- lub twj tso kua mis hydraulic (lub zog siv hluav taws xob hloov mus rau hydraulic zog)- faib valve- lub tog raj kheej lub tog raj kheej (lub zog hydraulic hloov mus rau hauv lub tshuab hluav taws xob)- paub txog lub thoob txav
Cov muaj pes tsawg leeg thiab kev ua haujlwm ntawm lub zog system
Cua nkag system-mesh npog → hose → cua lim → hose → turbocharger → hose → intercooler → hose → cav
· Exhaust system - supercharger → expansion sib koom → muffler → exhaust yeeb nkab
Txias qhov system- dej tank → hose → thermostat → twj tso kua mis → diesel cav → hose → dej tank
Throttle tswj qhov system-stepper lub cev muaj zog → reducer → cab iav tsav → throttle cable → diesel cav throttle - siab tsis siv neeg ceev, tsis tshua muaj siab ceev txwv hloov
· Roj System--
Roj inlet system: roj tank → hose → tes roj twj tso kua mis → coarse lim → nplua lim → diesel cav
Roj rov qab system: diesel cav → hose → roj tank (cov roj rov qab ntim kuj loj, siv nws rau ib nrab txias)
