I. Kev txhais thiab lub hauv paus ntsiab lus ua haujlwm
Mechanical excavator thiab hydraulic excavator yog ib hom mining machinery. Mechanical excavator yog siv zawv zawg khiav los yog saw txav, tsav lub thoob pas nrig thiab thoob pas nrig accessories mining machinery. Hydraulic digging yog kev siv tshuab hydraulic, los ntawm hydraulic lub tog raj kheej los txhawb cov hydraulic kheej kheej pas nrig, thoob pas nrig thiab thoob pas nrig accessories mining machinery. Qhov sib txawv tseem ceeb ntawm cov neeg kho tshuab excavator thiab hydraulic excavator yog qhov sib txawv ntawm lub hwj chim mechanism thiab kev sib kis mechanism.
Mechanical excavator feem ntau siv lub cav diesel, roj av cav lossis lub cev muaj zog ua lub zog; Kev khawb hydraulic feem ntau yog siv lub tshuab hydraulic tsim los ntawm lub cav diesel, hydraulic twj tso kua mis thiab hydraulic lub cev muaj zog raws li lub zog thiab kev tswj xyuas.
Ii. Qhov txawv
1. Cov khoom siv hluav taws xob sib txawv: cov tshuab excavators siv cov cav diesel, roj av cav lossis lub cev muaj zog raws li cov khoom siv hluav taws xob, thaum hydraulic excavators tsuas yog siv cov tshuab hydraulic tsim los ntawm cov cav tov diesel, hydraulic twj thiab hydraulic motors raws li cov khoom siv hluav taws xob thiab kev tswj xyuas.
2. Ntau hom kev ua haujlwm: lub tshuab excavator ua haujlwm lub thoob pas nrig txav los ntawm lub joystick hauv lub cab, thaum lub hydraulic excavator ua haujlwm los ntawm hydraulic system tsav tswj qhov system.
3. Kev saib xyuas nyuaj yog txawv: kev saib xyuas ntawm cov tshuab excavator yog qhov nyuaj, thiab cov khoom seem xws li cov sprocket yuav tsum tau lubricates thiab hloov tsis tu ncua; Kev saib xyuas ntawm hydraulic khawb yog qhov yooj yim, thiab tsuas yog cov khoom tseem ceeb xws li hydraulic roj thiab lim cov ntsiab lus yuav tsum tau hloov tsis tu ncua.
4. Kev ua haujlwm sib txawv: kev ua haujlwm yooj yim, kev ua haujlwm thiab kev ua haujlwm ntawm hydraulic khawb yog zoo dua li cov tshuab khawb tshuab, tshwj xeeb tshaj yog nyob rau hauv qhov chaw me me lossis thaum yuav tsum tau ua haujlwm zoo.
5. Tus nqi sib txawv: cov nqi tsim khoom thiab cov nqi siv txhua hnub ntawm hydraulic khawb yog siab dua li ntawm cov tshuab khawb tshuab.
