Raws li lub hauv paus tseem ceeb txuas ntxiv lub peev xwm ua haujlwm ntawm lub tshuab excavator, kev xaiv ntawm cov ntaub ntawv ncaj qha cuam tshuam rau lub load-cov kabmob muaj peev xwm, kav ntev, thiab kev nyab xeeb ntawm cov khoom siv. Hauv qhov nyuaj thiab puas tau- hloov chaw tsim kho, tsuas yog los ntawm kev cia siab rau siab - cov ntaub ntawv ua tau zoo thiab cov txheej txheem tsim khoom muaj peev xwm tuaj yeem tuav ruaj khov ua haujlwm nyob rau hauv ntev - nrug, siab - thauj khoom.
Tam sim no, cov qauv tseem ceeb ntawm cov caj npab txuas ntxiv feem ntau siv siab -lub zog qis- alloy structural steel. Cov qib ib txwm muaj cov txiaj ntsig zoo tshaj plaws thiab kev sib tw toughness, tso cai rau lawv tuaj yeem rov kho dua thiab cuam tshuam cov loads thaum ua kom muaj kev sib haum xeeb. Tom qab quenching thiab tempering, hom hlau no tau ua kom zoo cov nplej thiab txo cov kev ntxhov siab sab hauv, txhim kho kev qaug zog thiab ua tau raws li cov kev xav tau ntawm kev ua haujlwm ntev - lub sij hawm cyclical. Rau kev thauj khoom hnyav lossis kev ua haujlwm tshwj xeeb, qee lub caj npab txuas ntxiv yuav siv ntau dua - lub zog hlau alloy, ntxiv los ntawm kev kho cua sov hauv zos los txhim kho cov tawv tawv thiab hnav tsis kam ntawm qhov tseem ceeb ntawm kev ntxhov siab.
Sab hauv stiffeners thiab reinforcing thav duab ntawm caj npab feem ntau siv tuab - cov phaj steel phab ntsa los yog cov ntoo khaub lig tshwj xeeb -section profiles. Los ntawm qhov tsim nyog layout, tag nrho rigidity yog txhim kho, tiv thaiv ntau deformation thaum extension thiab luffing. Kev sib txuas cov pins thiab bushings feem ntau yog ua los ntawm siab- zoo carbon steel los yog alloy structural steel, thiab deg hardened los yog chrome-plated los txo cov coefficient ntawm kev sib txhuam, txhim kho hnav tsis kam thiab corrosion kuj, thiab xyuas kom meej du ntev - lub sij hawm ua hauj lwm ntawm cov articulated qhov chaw. Hydraulic piping cov ntaub ntawv hais txog kev ua haujlwm siab thiab kev tiv thaiv kev laus, feem ntau siv cov txheej txheem sib xyaw ntawm cov roj hmab tshwj xeeb thiab cov khoom siv hluavtaws kom ntseeg tau tias tsis muaj dej los yog deformation nyob rau hauv siab -siab hydraulic siab.
Hauv kev tsim khoom, vuam zoo yog qhov tseem ceeb rau kev ua haujlwm ntawm cov ntaub ntawv. Kev siv qis- hydrogen vuam pas nrig thiab preheating thiab post- cov txheej txheem cua sov yuav txo tau qhov kev pheej hmoo ntawm kev sib tsoo ntawm cov welds, thiab tsis yog - kev ntsuam xyuas kev puas tsuaj ua kom cov welds tsis tu ncua thiab ntom ntom. Qhov kev ua kom zoo tshaj plaws ntawm cov ntaub ntawv thiab cov txheej txheem no muab qhov kev nthuav dav ntxiv rau lub teeb yuag, siab - lub zog, thiab cov qauv tsim muaj kev ntseeg siab, ua rau kev ua haujlwm tsis tu ncua thiab ruaj khov hauv cov chaw hnyav xws li mine stripping, siab - nce lub hauv paus pits, thiab dej dredging, muab kev lav zoo rau kev ua haujlwm zoo ntawm kev tsim kho tshuab.
