Hydraulic excavator rudzi rwemichina yekuvaka yakashandiswa zvakanyanya, inoshanda mukuvaka migwagwa, kuvaka mabhiriji, kuvaka dzimba, kuchengetedza mvura yekumaruwa, kusimudzira ivhu uye mamwe minda.Inogona kuonekwa kwose kwose mukuvakwa kwenhandare dzendege, zviteshi, njanji, minda yeoiri, migwagwa mikuru, migodhi, uye madhamu.
Vazhinji vashandisi vekuchera vanodzidza iyo yekuchera kubva kuna vatenzi vavo.Ivo vane hunyanzvi mukushanda kwemucheri, asi havazive zvakawanda nezve chimiro chese uye misimboti yemucheri.Nhevedzano yezvinyorwa zveruzivo, zvikamu zve5, zvichatsanangura ruzivo rwekutanga rwevacheri kubva kuzvinhu zvekuchera mucherechedzo, chassis kusangana, dhizaini yekushanda, musangano wepamusoro wepuratifomu, hydraulic basic knowledge, etc. kubva pakadzika kusvika pakadzika.
1. Kurongwa kwevacheri
1. Maererano nemaitiro ekushanda: imwe-bucket excavator uye yakawanda-bucket excavator, iyo inowanzochera ndeye-single-bucket excavator, migodhi mikuru chete inoshandisa bucket-wheel excavator, kune mabhakiti akawanda, uye rotary operation.
Iyo yakajairika ndeye single bucket excavator (Carter 320D)
Multi-bucket excavator yemigodhi mikuru
2. Zvinoenderana nedhiraivha modhi: yemukati combustion injini drive, electric drive, compound drive (hybrid)
Kazhinji inofambiswa neinjini yekupisa yemukati (injini yedhiziri)
Kuchera foshoro yemagetsi (mberi kwefoshoro yekuchera)
3. Maererano nenzira yekufamba: crawler type uye tire type
4. Maererano nechishandiso chekushanda: foshoro yepamberi nebadza rekumashure
2. Nhanganyaya kune chimiro chekuchera
Mazita ezvikamu zvemucheri
Muchina wese unogona kukamurwa kuita zvikamu zvitatu zvakarongeka: chassis gungano, dhizaini yekushandisa, uye yekumusoro chikuva musangano.
Kuumbwa uye basa regungano rechassis:
1. Tsigira uremu hwechikamu chepamusoro chemucheri.
2. Simba rekushandisa uye actuator yekufamba uye kutungamira.
3. Tsigira simba rekuita rechishandiso chekushanda panguva yekuchera.
Izvo zvikamu zvikuru zvechasisi:
1. Iyo yepasi furemu muviri (welding zvikamu),
2. Mavhiri mana uye bhanhire rimwe (mavhiri ekufambisa, mavhiri ekufambisa, sprockets anotsigira, rollers, crawlers).
3. Dozer blade uye humburumbira.
4. Central rotary joint.
5. Swivel raceway ring (slewing bear).
6. Travel reducer uye motokari.
Yakaputika maonero ezvikamu zvikuru zvekusangana kwechasisi
Chimiro chechimiro uye basa: Muviri wemuviri (welding zvikamu) -- muviri mukuru wechasisi yese, inotakura zvese zvemukati nekunze masimba uye nenguva dzakasiyana, mamiriro ekushanda akaomarara, uye zvinodikanwa zvezvikamu zvakakwirira.Pane zvimwe zvinodikanwa zvekufananidzwa kwematanda ekuruboshwe nekurudyi anokambaira, zvikasadaro simba guru remberi richaitika, ringave risingafadzi kune zvikamu zvechimiro.
4~Mavhiri mana nebhandi rimwe chete, kutsigira kuuraya
Kutungamira vhiri uye tensioning mudziyo: Kutungamira vhiri uye
tensioning mudziyo: tungamira gwara rekufamba kwenjanji, gadzirisa dhigirii rekunetsa kwe track, uye kuderedza kuramba.
IDLER uye tensioning mudziyo
Carrier sprockets uye track rollers: Iwo anotakura sprockets anoita basa rekutsigira track.Rollers inotamba basa rekutsigira uremu
Carrier roller uye track rollers
Ichi chimiro chimiro chekuchengetedza-chisina, pasina kuwedzera girisi.
Chimiro che sprocket chinotsigira uye vhiri rinotsigira rezvicherwa zvakakura zvakasiyana zvishoma, asi musimboti wakafanana.
Sprocket: inotyaira muchina wese kufamba nekutendeuka
Track link Assy
Slewing bearing
--Batanidza motokari yepamusoro uye yepasi, kuitira kuti motokari yepamusoro inogona kutenderera ichitenderera motokari yepasi uye kutakura nguva yekupidigura panguva imwe chete.
Iyo rollers (mabhora) mumhete ye orbital inoda kugadzwa nguva dzose, uye kune maviri maitiro ekuwedzera bhotela kubva parutivi uye kuwedzera bhotela kubva kumusoro.
Inofamba mota + inoderedza: ipa simba rine simba (torque) kutyaira iyo sprocket uye crawler bhandi, kuitira kuti mucheri apedze kufamba uye kufambisa zviito.
