1. Tswj cov teeb meem ntawm cov roj to
Lub kaw lus hydraulic tswj muaj ntau yam kev thov, thiab nws yooj yim rau cov teeb meem thaum siv, ib qho ntawm cov roj to. leakage tsis tsuas yog ua rau muaj kev sib kis ntawm cov roj hydraulic, tab sis kuj tseem cuam tshuam rau kev ua haujlwm zoo ntawm kev tswj hwm. Qhov no feem ntau yog vim cov roj hydraulic ua lub luag haujlwm tseem ceeb hauv kev sib kis thiab tswj cov txheej txheem ntawm cov cuab yeej siv tshuab, thiab kev tswj hwm ntawm hydraulic roj kub yog nruj tshwj xeeb. Yog tias cov roj hydraulic ua haujlwm ntev ntev hauv lub xeev overhe, nws yuav cuam tshuam rau kev ua haujlwm ntawm tag nrho lub cev. Tsis tas li ntawd, kev sib khi tsis zoo ntawm kev tswj xyuas hydraulic kis tau tus mob tuaj yeem ua rau cov roj to thiab ib puag ncig muaj kuab paug Yog li ntawd, hauv kev tsim thiab tsim cov txheej txheem ntawm cov cuab yeej siv tshuab, tshwj xeeb yuav tsum tau them rau cov teeb meem ntawm cov roj hydraulic thiab cov roj to. Ib tus neeg saib xyuas tshwj xeeb tuaj yeem raug xaiv los tiv thaiv kev ua haujlwm tsis zoo los ntawm hydraulic roj paug thiab roj to.
2. Daim Ntawv Thov Kev Txuas Txuas Txuas Ntxiv (CVT)
Cov kis tau tus mob yog ib feem tseem ceeb ntawm hydraulic kis tau tus mob tswj system, tuaj yeem txhim kho cov txiaj ntsig ntawm daim ntawv thov kev tswj hwm. Yog li ntawd, nyob rau hauv tus txheej txheem ntawm cov cuab yeej siv tshuab tsim thiab kev tsim khoom, qhov tseem ceeb yuav tsum tau muab rau kev siv cov cuab yeej hloov pauv ceev kom muaj kev ruaj ntseg zoo rau kev siv cov tshuab tswj.
Daim ntawv thov kev hloov pauv tsis tu ncua hauv kev tswj hwm hydraulic kis tau tus mob tuaj yeem ua tiav kev hloov pauv ntawm kev sib kis ceev, thiab txo qhov cuam tshuam rau kev ruaj ntseg ntawm lub kaw lus thaum lub sij hawm hloov ntawm cov lus tsa suab sib txawv. Nyob rau hauv xyoo tas los no, nrog kev txhim kho txuas ntxiv ntawm kev lag luam kev lag luam, kev sib kis tsis tu ncua tau siv dav hauv kev tsim kho tshuab thiab tsim khoom, thiab tau dhau los ua cov qauv tseem ceeb ntawm hydraulic kis tau tus mob. Yog li ntawd, kev txhim kho txuas ntxiv ntawm daim ntawv thov kev sib txuas tsis tu ncua sib kis tau zoo heev txhim kho kev tswj lub peev xwm ntawm hydraulic kis tau tus mob tswj qhov system.
3. Tswj ntawm roughness
Tswj qhov roughness ntawm qhov chaw thiab mating nto yog ib qho tseem ceeb ntawm hydraulic mechanical kis system tsim. Feem ntau, qhov tsim nyog tus nqi roughness yog 0.2 ~ 0.4. Feem ntau, kev sib tsoo ntawm roughness yuav siv txoj kev sib tsoo los yog dov. Rolling yog ib txoj kev ua ntau dua, uas muaj qhov zoo ntawm qhov raug thiab ua haujlwm siab piv rau kev sib tsoo, thiab tuaj yeem ua kom lub neej ua haujlwm siab tshaj plaws ntawm hydraulic qhov chaw. Txawm li cas los xij, muaj nyob rau hauv kev lag luam uas yog tias qhov chaw ntawm lub foob yog du dhau lawm, nws yuav cuam tshuam rau cov roj tuav cov nyhuv ntawm qhov chaw sib cuag, yog li cuam tshuam rau lubrication thiab, thiab yuav ua rau muaj qhov txawv txav ntawm lub suab nrov hauv hydraulic. Yog li ntawd, nyob rau hauv tus txheej txheem tsim tiag tiag, qhov roughness ntawm qhov chaw thiab mating nto yuav tsum tau txiav txim siab ua ke nrog cov kev siv tiag tiag.
4. Ntshiab dej nruab nrab siv tshuab
Piv nrog rau cov roj hydraulic ib txwm siv raws li qhov nruab nrab kis tau tus mob, cov dej ntshiab hydraulic kis tau tus mob siv tshuab siv cov dej ntshiab raws li qhov nruab nrab tsis tsuas yog txo cov nqi tsim khoom ntawm hydraulic tswj system, tab sis kuj zoo kawg nkaus daws teeb meem xws li roj to. Siv cov dej ntshiab raws li qhov nruab nrab hloov hluav taws xob, ntawm ib sab, txo cov nqi hluav taws xob, thiab ntawm qhov tod tes, tuaj yeem zam kev ua qias tuaj ib puag ncig los ntawm cov khoom siv ua haujlwm. Siv cov dej ntshiab raws li qhov nruab nrab muaj cov kev xav tau siab, thiab tshwj xeeb yuav tsum tau siv los kho cov dej ntshiab kom ntseeg tau tias nws tuaj yeem dhau los ua qhov nruab nrab rau lub zog hloov dua siab tshiab.
Piv nrog rau cov roj hydraulic, cov dej ntshiab muaj qhov qis dua compressibility coefficient, thiab nws yog nplaim retardant thiab ib puag ncig tus phooj ywg. Txawm hais tias ib qho tshwm sim thaum lub sijhawm ua haujlwm ntawm cov khoom siv, nws yuav tsis muaj kev cuam tshuam loj rau ntawm qhov chaw tsim khoom. Yog li ntawd, cov neeg ua haujlwm muaj feem cuam tshuam yuav tsum tau ua kom cov txheej txheem tshawb fawb ntawm cov dej ntshiab hydraulic tswj tshuab, thiab sai sai nrov daim ntawv thov ntawm cov dej ntshiab hydraulic kis tau tus mob, yog li cov cuab yeej no tuaj yeem pab txhawb kev txhim kho tag nrho ntawm kev tsim khoom lag luam.
Tsis tas li ntawd, cov neeg ua haujlwm tseem ceeb yuav tsum ua raws li lawv tus kheej cov kev xav tau ntawm kev siv tshuab, ua ke nrog lawv tus kheej tsim kev paub, thiab tsim nyog xaiv cov dej ntshiab los yog lwm yam kua raws li lub zog hloov nruab nrab kom ntseeg tau tias cov yam ntxwv ua tau zoo raws li cov kev xav tau siv, tag nrho. Ua kom pom qhov zoo ntawm daim ntawv thov ntawm hydraulic kis tau tus mob tswj qhov system thiab muab lub zog lav ntsuas los xyuas kom meej qhov kev tswj hwm thiab kev ruaj ntseg ntawm qhov system.
