Lub cutter suction dredger yog ib qho khoom siv tseem ceeb hauv kev ua haujlwm niaj hnub dredging. Nws lub luag haujlwm tseem ceeb suav nrog kev siv lub tshuab hydraulic tag nrho los tsav lub taub hau cutter uas txiav thiab ua rau cov av qis hauv qab, tsim cov slurry uas yog thauj los ntawm cov yeeb nkab nqus mus rau thaj chaw. Cov neeg tsim khoom ntawm cov cuab yeej no feem ntau tshwj xeeb hauv hydraulic tsav tshuab, hnav- cov ntaub ntawv tiv taus, thiab cov dej tsis zoo, muab cov tshuab tseem ceeb rau cov haujlwm xws li chaw nres nkoj channel tu, dej desilting, thiab kev kho lub pas dej ib puag ncig.
1. Kev ntseeg siab ntawm cov hydraulic system, nrog rau kev sib txuam thiab kev cuam tshuam ntawm cov khoom xws li cov twj tseem ceeb, lub cev muaj zog, thiab cov khoom sib dhos valve;
2. Txiav efficiency thiab hnav tsis kam ntawm lub taub hau cutter, raws li cov av sib txawv (xws li, av nplaum, gravel, tawv txheej txheej) yuav tsum muaj cov txheej txheem sib txawv;
3. Slurry twj tso kua mis thauj mus deb thiab concentration tswj, uas ncaj qha cuam tshuam kev ua hauj lwm zog noj thiab paug ntau yam.
