18 inch cutter suction dredger for sand dredging

Overview

This ship suit shadowing sea (waves less)and follow water area operation requirements that is Non-self-propelled dredger assembled the whole steel welded.
Main Principle:first through Bridge hydraulic cutter underwater excavation of soil was excavated sediment rotating reamer driven with water to form a fluid medium containing certain ores, located in the hydrodynamic cutter circle at the mouth of the mud pump suction , into the pump and get some energy out through the pipeline.

Main Features of cutter suction dredger

1) Standard design, allowing early delivery and low price.

2) Completely assembled and fully tested before delivery.

3) Simple, rapid assembly and dismantling.

4) Ready for operation on arrival at site.

5) Spare parts available from stock.

6)  Transportable by road, rail or sea.

7) Reliable hydraulic system.

8) Efficient fuel consumption.

Pump for Sand Dredger

1.Structure good,WN dredger pump adopts semi double shell structure, which reduces unnecessary auxiliary structure and process structure.
2.Advanced hydraulic model with high efficiency. The efficiency of the WN mud pump is 2-3 percentage point higher than before. In this way, lower energy consumption can be achieved at the same output.
3.Good wear resistance with long life.
Also can install Imported Original Pump from Abroad.

Engine for the Sand Dredger

Cummins Engine is global warranty,spare parts can be available in short time.
Environmental protection and Energy conservation
The main engine driven the dredge pump and auxiliary engine drives hydraulic system including cutter,swing winches,ladder winch and the spud rams etc. And the emergency genset supplies electricity for lighting and emergency use when the dredge doesn't work.

Pontoon for the Sand Dredger

The dredger pontoon is with dismantle type and box-like structure,  In order to transported convenient by truck, easy installation at working site.

 And it is sandblasted and painted by 4 layers of marine epoxy paint suitable for saltwater service.The Zinc anode can be used to give better anti-corrosion function.

Hydraulic system for the Sand Dredger

An integral hydraulic system includes hydraulic cutter head, hydraulic winch, hydraulic pump, hydraulic valve manifold, solenoid valve, hydraulic pipes, hydraulic components, electrical actuator and so on.
The hydraulic system requirements are very high and strict, it is the main artery of the entire dredger. The swing winches,lifting winch and cutter head are all driven by separate hydraulic motors.
The spud cylinder is hydraulic powered to lift spuds, the alternate swing of spuds will move the dredger.
