Raws li ib qho ntawm cov kev lag luam ntawm cov khoom siv kho tshuab, hydraulic lub tog raj kheej tuaj yeem nce qib hauv pawg. Qhov kev thov no muaj lub hauv paus kev lag luam thiab chaw lag luam. Lub hom phiaj kev tsim kho ntawm kev lag luam kev lag luam yog tsim kom muaj hydraulic lub tog raj kheej kev lag luam chaw ua si, tswj hwm lub tog raj kheej hydraulic, sib sau ua ke tsawg thiab tawg tsoomfwv thiab cov chaw muaj txiaj ntsig, qhia nws cov txiaj ntsig zoo, qhia txog cov yam ntxwv ntawm kev lag luam thiab nplai, thiab kev txhawb nqa txhim kho kev lag luam thiab Raws li kev tsim kho kev lag luam-kev pabcuam kev lag luam, txhim kho kev pabcuam pej xeem kev pabcuam platform, thiab tsim kev koom tes sab hauv thiab sab nraud ib puag ncig ntawm cov lag luam uas ua tau zoo rau kev lag luam pov thawj.
Lub tog raj kheej hydraulic txhim kho mus rau qhov kev ua haujlwm siab, kev ua haujlwm zoo, kev ntseeg siab, thiab ua tiav lub kaw lus; kev txhim kho ntawm kev siv hluav taws xob tsawg, lub suab qis, kev vibration, tsis muaj dej xeb, tswj kev ua qias tuaj, siv daim ntawv thov dej-tawm, thiab lwm yam kom tau raws li kev tiv thaiv ib puag ncig; txhim kho kev sib xyaw ua ke thiab lub zog siab Density, txawj ntse, mechatronics, lub teeb thiab me me micro hydraulic yam; nquag txais yuav cov thev naus laus zis tshiab, cov ntaub ntawv tshiab, khoom siv hluav taws xob, kev hnov thiab lwm yam kev tshaj lij.
