Large Customized Dual Pump Cutter Suction Dredger With 18m Dredging
Depth
1. Dual Pump Dredger
The appearance is still the same, but this dredger has two pumps,
one main pump in the reamer and another sub-pump in the cabin. This
design maximizes suction and allows for deeper digging where the
mud is transported further. The biggest drawback is that the cost
is higher than the submersible dredger.
2. Types Of Dredgers
The cutter suction dredger is a fixed type of dredigng equipment.
After fixing the position by the positioning pile, and then pulling
the left and right sides alternately by the winch, the reamer can
perform the fan-shaped movement, and the rotating reamer penetrates
the water and swings in the soil. At the same time, the sediment in
the soil is sucked into the pump through the suction pipe, and then
the sediment is directly sent to the mud treatment area through the
pipeline.
The cutter suction dredger loosens the soil at the bottom of the
river or the seabed using a rotating reamer, sucks it into the pump
through a straw, and then sends it to the mud treatment zone
through the mud pipe.
And the modern precision instruments can accurately indicate the
dredging profile and the side-breaking slope. When the size of the
cutter suction dredger is very large, it is usually equipped with
self-propelled equipment, so that easy on-site movement can be
achieved.
Conventional cutter suction dredgers are more suitable for use in
construction environments where the soil is only soil and small
stones. However, it is now possible to adapt to more construction
environments by replacing the reamer. For example, broken stones
are not very hard stones or water plants that cut off the bottom of
the water.
Although small cutter suction dredgers are not equipped with
self-propelled equipment, they are the least expensive and
economical to dredge compared to other types of dredger dredgers.
