I. Cav System Faults
1. Cov pa luam yeeb dub lossis xiav: Cov pa luam yeeb dub qhia tias tsis ua tiav kev sib txuas, thaum cov pa luam yeeb xiav qhia tias cov roj muaj feem cuam tshuam rau kev sib txuas; ob qho tib si muaj feem xyuam rau overload.
2. Txo lub zog thiab qeeb nrawm: Ntev ntev siab - lub cav ua haujlwm ntawm lub cav ua rau txo qis zog.
3. Ceev Cov Roj Deterioration: Kub kub ua rau cov roj oxidation thiab deterioration, ua rau poob ntawm lubrication thiab kev tiv thaiv, uas yuav ua rau muaj teeb meem loj xws li lub tog raj kheej cov qhab nia thiab bearing qaug dab peg.
II. Hydraulic System Abnormalities
1. Hydraulic Roj Kub Kub nce 15-20 degree: Qhov no qhia tau tias cov roj viscosity txo qis, kev laus cov ntsaws ruaj ruaj, thiab muaj kev pheej hmoo ntawm cov to.
2. Kev txav qeeb lossis tsis muaj zog: Piv txwv li, malfunctioning start/stop of the vibratory roller or heavy steering qhia tias tsis txaus hydraulic motor output.
3. Pipe Leaks los yog tawg: Lub zog ntau dhau tuaj yeem ua rau cov dej xau lossis txawm tias cov yeeb nkab tawg ntawm cov pob qij txha lossis cov hoses, ua rau muaj kev phom sij.
III. Kev puas tsuaj rau kev vibration bearings thiab kis tau tus mob
1. Cov Kabmob Tsis Txaus Siab lossis Tshaj Tawm: Kev ua haujlwm dhau los ua kom lub neej ntev ntawm kev co bearings los ntawm 30% -50%, ua rau lub suab "humming" lossis kub dhau.
2. Loose Eccentric Blocks los yog Hnav Spline Shafts: Qhov no ua rau tsis ruaj khov amplitude, tshuab vibration, thiab cuam tshuam rau compaction.
IV. Structure Component Fatigue thiab Weld Cracks
1. Microscopic Cracks nyob rau hauv Steel Wheel Welds: Accumulated hlau qaug zog, tshwj xeeb tshaj yog nyob rau hauv lub hub kev twb kev txuas thiab reinforcing rib cheeb tsam.
2. Ncej Deformation lossis Cracks: Kev ua tsis tiav ntawm cov khoom siv poob siab ua rau muaj kev sib kis ncaj qha ntawm kev cuam tshuam quab yuam, ua rau cov qauv kev puas tsuaj.
V. Lwm yam txhaum
1. Dej Kub Kub Siab Tshaj 95 degree: Lub tshuab ua kom txias yog overloaded, muaj peev xwm ua rau tsis siv neeg kaw.
2. Lub tswb nrov nrov: ECU tshaj tawm cov lej txhaum xws li P0234 (dhau- txhawb siab) thiab P0087 (hauv qab- roj siab).
3. Ua kom nrawm nrawm nrawm dua thiab ncua lub kauj tsheb: Qhov no cuam tshuam rau kev ua haujlwm raug thiab kev nyab xeeb ntawm kev tsim kho, tshwj xeeb tshaj yog thaum ua haujlwm ntawm qhov chaw siab tshaj qhov kev pheej hmoo siab dua.
