Cov laj thawj tseem ceeb rau qhov tsis ua haujlwm ntawm cov ntsaws ruaj ruaj hydraulic yog: teeb meem cov khoom siv, teeb meem ntim khoom, teeb meem qauv tsim qauv, teeb tsa kev xaiv, foob sib dhos, muaj kuab paug nyob hauv hydraulic thiab nws cov teeb meem siv. Cov ntsiab lus muaj npe hauv qab no.
1. Kev ntim ntawm cov ntsaws ruaj ruaj hydraulic: lub cev puas tsuaj: ntim tsis zoo; hlau xaim thiab cov hlua dai cov ntsaws ruaj ruaj; tshuaj lom neeg puas tsuaj: hnub ci; ze rau ntawm lub qhov cua kub.
Qhov tshwm sim: Cov plua plav txuas rau qhov hydraulic foob los yog khawb lub ntsaws ruaj ruaj; ntu ntu ntawm lub foob raug puas ntsoog thiab cuam tshuam txog qhov sib khi nyhuv; ua kom sai sai ntawm kev siv roj hmab thiab hloov qhov loj me; nrawm laus kev laus ntawm lub foob.
2. Kev xaiv ntawm cov ntsaws ruaj ruaj hydraulic: cov khoom siv thiab nruab nrab tsis sib xws; nws tsis haum rau qhov kub thiab txias ntawm qhov siv; cov khoom siv los yog daim ntawv sib khi tsis tsim nyog; cua sov cua sov ua haujlwm; tshuaj lom neeg puas tsuaj; lub foob kuj mos dhau.
Qhov tshwm sim: kev nthuav tawm ntau dhau los lossis nqis ntxiv ntawm lub foob; yooj yim laus ntawm lub foob; nkag thiab nrov nrov; embrittlement, melting los yog caws pliav ntawm cov roj hmab; nthuav, kev cog lus lossis ua tawv tawv ntawm lub foob; nyem rau hauv qhov sib txawv thiab cov yas deformation.
3. Kev ua qias tuaj hauv qhov hydraulic thiab nws txoj kev siv: tshwm sim los ntawm cov pa paug lossis cov nplaim dej; ua kom lub npoo puab ntawm lub tog raj kheej; dej nyob hauv cov roj; cov khoom haum hauv qhov system.
Qhov tshwm sim: txau vim yog hnav cov ntsaws ruaj ruaj; hydrolysis los ntawm kev xau, xws li polyurethane, to, sib tsoo thiab tawg
4. Cov khoom siv raw: xaiv cov khoom tsis zoo los yog teeb meem nrog cov khoom siv raw lawv tus kheej
Qhov yuav tshwm sim: Tawv tshwm sim los ntawm cov ntaub ntawv uas tsis raug raws li qhov yuav tsum tau ua lossis vim muaj kab mob porosity, looseness lossis ntau ntxiv cov sijhawm ntxiv thaum ua
5. Tus qauv tsim ntawm hydraulic cov ntsaws ruaj ruaj: O-ring compression tus nqi yog loj heev; cov kis loj dhau; lub sealing sib tsoo yog dav heev; lub qhov rooj sib khi nqaim yog nqaim dhau; qhov saum npoo tawv heev; lub siab tawm sai sai thiab nrog cua; qhov ntev ntawm lub plahaum thiab thev tsis raug; Tus nqi ntws nrawm dhau heev; qhov kev tiv tauj lub siab yog siab heev; lub kaw lus cua sov dissipation tsis zoo; cov yeeb nkab sib txuas tsis phim lub siab thiab siv cov khoom siv; muaj lub nraub qaum.
Qhov tshwm sim: hnav ua ntej; ntsaws ruaj ruaj yog xau rau hauv qhov sib txawv; siab txhuam, yooj yim kom sov, ua kom puas, thiab nkag; dav hlau hnav; hnav khaub ncaws hnyav; tso siab hnyav tawm; kev tsis tsim nyog preload ntawm cov ntsaws ruaj ruaj, yooj yim xau; hnav thiab roj Corrosion; adhesion hnav; loj kub nce ntawm qhov system, ua rau kev laus ntawm cov khoom sib khi; dej xau vim kev vibration lossis ntshav siab; foob hnav, lub neej luv luv, thiab lub foob tshaj.
6. Kev sib dhos ntawm cov ntsaws ruaj ruaj rau hydraulic: cov twj tsis tsim nyog; tsis muaj kev qhia tawm ntawm chamfers; kev teeb tsa tsis zoo lossis tsim ntev dhau; lub kaw lus yuav tsis xau; lub npoo ntawm qhov sib khi yog sib ntswg.
Qhov tshwm sim: kev puas tsuaj rau lub foob thiab ua rau lub sijhawm tsis ua haujlwm ntev; lub foob yog me ntsis txiav; O-ring yog twisted los yog xau vim qhov muab kauv tawg; lub Diesel nyhuv, lub foob raug scorched, thiab lub foob raug xau thaum lub sijhawm pib.
