Txhua tus neeg uas muaj kev paub txog kev siv tshuab yooj yim paub tias lub zog tuaj yeem hloov mus rau ntau hom. Siv qhov kev paub no rau cov tshuab hydraulic zoo tshaj plaws piav qhia lub zog poob. Lub zog poob nyob rau hauv lub hydraulic system ua rau lub zog poob, txo tag nrho cov system efficiency. Tsis tas li ntawd, lub zog poob no tau hloov mus rau hauv tshav kub, nce qhov kub ntawm cov roj hydraulic, ua rau cov roj deterioration, thiab thaum kawg ua rau cov khoom siv tsis zoo. Yog li ntawd, thaum tsim lub hydraulic system, txo qis zog poob yuav tsum yog ib qho tseem ceeb rau kev txiav txim siab, ntxiv rau kev ua kom tau raws li qhov yuav tsum tau ua.
Los ntawm qhov kev xav ntawm lub zog hluav taws xob- lub twj tso kua mis- xav txog cov kev ua haujlwm sib txawv ntawm cov actuators, qee zaum lub kaw lus yuav tsum muaj qhov siab txaus thiab tsis tshua muaj siab, thaum lwm zaus nws yuav tsum tau qis qis thiab siab siab. Yog li ntawd, lub siab - txwv tsis pub hloov pauv hloov twj tso kua mis yog qhov zoo dua vim tias nws cov nqi ntws sib txawv nrog lub zog siab. Thaum lub kaw lus siab txo qis, tus nqi ntws siab dua, ua tau raws li tus actuator txoj kev xav tau ceev ceev. Thaum lub kaw lus siab nce, tus nqi ntws txo raws li, ua tau raws li tus neeg ua haujlwm ua haujlwm stroke. Qhov no ua kom txaus siab rau tus actuator cov kev xav tau ntawm kev ua haujlwm thaum ua kom muaj kev siv hluav taws xob tsim nyog.
Hydraulic roj inevitably muaj kev nyuaj siab thiab ntws poob thaum ntws los ntawm ntau yam hydraulic li qub, thiab cov kev poob no yog ib feem tseem ceeb ntawm tag nrho lub zog poob. Yog li ntawd, xaiv qhov tsim nyog hydraulic Cheebtsam thiab kho lub siab ntawm lub siab li qub yog qhov tseem ceeb rau kev txo qis zog. Flow li qub yuav tsum raug xaiv raws li qhov kev tswj hwm qhov system, kom ntseeg tau tias lawv cov dej ntws tsawg kawg nkaus ua tau raws li qhov yuav tsum tau ua. Lub siab li qub yuav tsum tau xaiv ntawm qhov qis tshaj qhov ua tau, thaum tseem ua tau raws li qhov kev ua haujlwm ntawm cov khoom siv hydraulic.
Yog hais tias tus actuator xav tau kev tswj ceev, qhov ceev tswj Circuit Court yuav tsum ua raws li qhov yuav tsum tau ua thaum txo qis hluav taws xob poob. Cov kab hluav taws xob tswj kev ceev feem ntau suav nrog cov hluav taws xob tswj hluav taws xob, cov hluav taws xob tswj hluav taws xob, thiab cov hluav taws xob hluav taws xob tswj hluav taws xob. Throttling ceev tswj circuits muaj siab zog poob tab sis zoo tsawg -ceev stability. Volumetric ceev tswj circuits tsis muaj overflow los yog throttling poob, muab kev ua haujlwm siab tab sis tsis zoo qis - ceev stability. Txhawm rau kom ua tau raws li ob qho kev xav tau, lub kaw lus ntim ntim ceev tswj Circuit Court tsim los ntawm lub twj tso kua mis sib txawv ntawm lub siab sib txawv thiab lub valve tuaj yeem siv tau, txo qis qhov sib txawv ntawm lub throttling valve kom txo qhov poob siab.
Xaiv cov roj hydraulic tsim nyog kuj tseem ceeb. Thaum cov roj hydraulic ntws hauv cov kav dej, nws nthuav tawm viscosity. Cov viscosity ntau dhau ua rau muaj kev sib txhuam tseem ceeb hauv kev sib txhuam, ua rau cov roj ua kom sov thiab ua kom cov dej tsis kam. Conversely, tsis tshua muaj viscosity tuaj yeem ua rau xau thiab txo qhov system volumetric efficiency. Yog li ntawd, cov roj uas tsim nyog viscosity thiab zoo viscosity-cov yam ntxwv kub feem ntau yog xaiv. Tsis tas li ntawd, cov roj hydraulic muaj kev poob siab nyob rau hauv cov kav dej thiab qhov chaw poob siab; Yog li ntawd, kev tsim cov kav dej yuav tsum tsom kom txo cov yeeb nkab ntev thiab khoov.
