Txoj Cai Ntawm Cutter Suction Dredgers

Cutter suction dredgers ua tau zoo dredging los ntawm kev sib koom ua haujlwm ntawm lub hull, cutter choj, cutter taub hau, av nkos twj tso kua mis, pipeline system, thiab hwj chim unit. Lub taub hau cutter (30-50 rpm) rhuav tshem cov khib nyiab ntawm cov dej hiav txwv nrog cov hniav tig, tsim slurry (20-30% cov ntsiab lus ntawm cov khib nyiab). Cov av nkos twj tso kua mis (5-10m suction nqa, 20-50m lub taub hau) thauj cov slurry mus rau qhov chaw xaiv ntawm cov kav dej (0.3-0.8m txoj kab uas hla). Lub hwj chim unit (2000-8000kW) muab lub zog rau tag nrho lub nkoj. Nws txoj kev tswj hwm lub tshuab tuaj yeem saib xyuas qhov tob (qhov tseeb ± 0.1m) thiab qhov siab (yuam kev<5%) in real time, and it is widely used in waterway maintenance (such as improving navigation capacity) and land reclamation (efficiency up to 5000m³/h).
