1. Kev txwv qhov hnyav thiab qhov loj me
Rau feem ntau cov tshuab txawb, qhov hnyav yog qhov tseem ceeb heev. Hauv kev tsim tshuab, qhov yooj yim tshaj plaws kom paub tseeb tias lub tshuab muaj zog thiab kav ntev yog siv cov phaj tuab tuab. Qhov no ua rau lub tshuab tawv thiab txhim khu kev qha. Tab sis cov tshuab txawb feem ntau muaj qhov hnyav, thiab cov kev txwv no tuaj yeem sib txawv nyob ntawm lub tsheb loj thiab cov cai uas nws yuav tsum tau ua. Yog li, txhawm rau ua kom cov tshuab sib zog, cov tuam ntxhab yuav tsum sim ntau txoj hauv kev, xws li siv cov cuab yeej tsim kho tshuab computer, cov ntaub ntawv sib dua, lossis hloov ntawm cov khoom siv tshuab lossis hydraulic mus rau hluav taws xob. Qhov xav tsis thoob yog tias kev txiav qhov hnyav tuaj yeem kim heev - qee zaum cov hlau xaus rau pheej yig dua.
Tam sim no, cia peb tham txog lub zog ceev. Qhov no yog ib qho ntawm qhov sib txawv tseem ceeb ntawm mobile hydraulic systems thiab cov khoom lag luam zoo sib xws. Fais fab ntom yog tus nqi ntawm lub zog lub kaw lus tuaj yeem muab piv rau qhov loj me uas ua haujlwm. Tam sim no, tsis muaj lwm qhov system tuaj yeem phim lub zog ceev ntawm lub tshuab hluav taws xob hydraulic, thiab ncaj ncees, nws yuav ntev ntev ua ntej qhov ntawd tshwm sim.
Piv txwv li, lub bulldozer lub log tsav lub cev muaj zog tuaj yeem ua haujlwm ntawm qhov siab tshaj 400 bar, uas yog ob zaug tus qauv rau kev lag luam hydraulics. Xav txog qhov no: ib tug 300-horsepower (220 kW) tsav lub cev hnyav xwb 120 kg. Yog tias koj xav tias hnyav, cia peb muab piv rau lub tshuab hluav taws xob muaj hluav taws xob. A 300-horsepower electric motor yuav hnyav 1,360 kg-li 11 npaug hnyav dua li hydraulic.
Lub zog ceev piv ntawm radial piston motors twb siab txaus. Yog tias koj saib ntawm lub zog ceev piv ntawm inclined axis piston motors, koj yuav pom tias radial piston motors tseem qis dua. Lub inclined ncej piston lub cev muaj zog muaj kev sib xyaw ua ke ntawm cov hlau ruaj ruaj thiab cov kabmob hnyav, thiab ua haujlwm hauv cov khoom siv nrog cov ntawv thov ze li 400 bar nyob rau hauv feem ntau ua haujlwm. Ntawm lub zog ntawm 35 horsepower (26 kilowatts) nrog 5cc A2F5 lub cev muaj zog los ntawm Rexroth, nws hnyav tsuas yog 2.5 kilograms thiab tuaj yeem haum rau hauv lub tais mov.
Los ntawm kev ua kom lub zog ceev, qhov hnyav ntawm tag nrho lub tshuab tau raug txo. Rau OEMs, qhov no txhais tau hais tias cov tshuab tuaj yeem ua tau raws li cov qauv siv hluav taws xob nruj thiab txo qhov loj ntawm lub cav lossis lub cev muaj zog, uas feem ntau yog cov khoom kim tshaj plaws ntawm lub tshuab.
