Kev saib xyuas ntawm cutter suction dredgers yuav tsum tau ua kom zoo nyob rau hauv modules:
1. Kev soj ntsuam ib ntus: suav nrog hull corrosion (yuav tsum tau kho yog xeb tshaj 5%), hydraulic system roj siab (15-20MPa), thiab hluav taws xob rwb thaiv tsev (Ntau dua lossis sib npaug ntawm 1MΩ). Kev tiv thaiv kev saib xyuas tuaj yeem txo qhov kev pheej hmoo ntawm kev ua tsis tiav tam sim ntawd.
2. Core Component Maintenance: Lub taub hau cutter yuav tsum tau muab ntxuav thiab cov hniav cutter kuaj xyuas kev hnav txhua txhua 50 teev (hloov yog tias hnav ntau dua 1/3 ntawm qhov ntev). Lub impeller clearance ntawm cov av nkos twj tso kua mis yuav tsum tau khaws cia ntawm 2-3 hli kom sib npaug efficiency thiab hnav.
3. Lubrication thiab Corrosion tiv thaiv: yuav tsum tau ua raws li cov qauv, xws li epoxy asphalt xim qhuav zaj duab xis thickness Ntau tshaj los yog sib npaug zos rau 200μm, thiab bearings yuav tsum tau greased txhua lub limtiam kom txog thaum dhau.
4. Cov txheej txheem kev khiav hauj lwm: Qhov tseem ceeb yog muab tso rau ntawm kev tswj ceev (30-50rpm) thiab cov lus teb tsis raug (shutdown yog tias cov roj kub siab tshaj 80 degree). Kev saib xyuas raws caij nyoog, xws li hloov mus rau qhov kub thiab txias hydraulic roj (-30℃ncuav point) nyob rau lub caij ntuj no, tuaj yeem hloov mus rau huab cua ua haujlwm. Kev saib xyuas zoo tuaj yeem txo qis kev poob qis los ntawm 30% (cov ntaub ntawv los ntawm Tuam Tshoj Dredging Association).
