The river jet suction dredger is an efficient dredger. The main components of this ship are a set of high-pressure water pumps and a set of sand suction pumps. The high-pressure water pump pushes the water through the high-pressure water gun into the bottom sediment layer, and the sand splashes around the sand suction head. It is sucked by the sand suction pump and discharged from the upper suction pipe to the designated position. In this way, the whole work process is completed with one spray and one suction. This ship is widely used in dredging and sand fetching projects in reservoirs, artificial lakes, rivers, and ports.
Brief introduction of the parameters of the river jet suction dredger: After the sand is washed away by the water pump, the sand is sucked up by the powerful sand pump and then transported out through the pipeline.
Workload: 100-1000 tons/hour;
Sand pumping depth: 5-20 meters;
Power: diesel engine or generator set
Work process:
The river jet suction dredger can be either stationary or self-propelled, although the self-propelled can only be clearly shown when the equipment is moved to a new dredging site. It is usually equipped with a propeller behind the hull to achieve the function of advancing in the water.
The river jet suction dredger is always stationary when it is working, and it will perform the sand pumping work in a fixed place in a designated place.
The jet suction sand boat utilizes the “destroy” process. When the sand at the bottom generates pressure through water pressure or local instability causes density flow to flow down the slope, a breakthrough occurs, and the jet suction sand boat intentionally produces this destructive effect. The dredger are equipped with sand suction heads. They use centrifugal pumps to provide entrained flow, that is, carry materials along the water flow, and use hydraulic transportation to transport solids or cement slurry from the dredging site to the ground through pipelines, and then to the discharge site.
feature
- High efficiency, large amount of sand and long conveying distance.
- The loading and unloading is very simple and fast, whether it is on the sea or on the shore, the operation is simple and easy to control.
- Self-propelled system, which can be propelled in place when moving.
- Good economic benefits. Complete the excavation and transportation of materials at one time.
- The hull consists of multiple pontoons connected by a proven coupling system.
- Low fuel consumption and lowest overall operating cost
- There is an operating room in the ship, which can be operated by one person in a spacious and low-noise operating cabin, with more efficient work efficiency. The controls and instruments are installed on the ergonomic dashboard.
- Good contact with all parts, especially the vulnerable parts of the mud pump. Fresh water cooling system.
- The dredger can be made according to customer requirements.
Significance of dredging with a dredger:
Dredging has developed into a very professional activity. The capital cost of the plant and equipment involved can be as high as millions of dollars; the largest modern dredger found in the world today can transport hundreds of thousands of cubic meters of material per week. Dredgers can bring great benefits. They allow the safe development of new ports and ports. They create conditions for burying pipelines in the seabed, maintaining and protecting beaches from erosion, extracting oil from deep-sea wells, and navigating under safe conditions.
As long as there is sufficient water depth to allow the dredger to operate, dredging can be carried out. Therefore, dredgers can be found in coasts, rivers and canals. They can be found in lakes and ponds far away from the sea, as well as in exposed offshore locations away from land. Dredgers operate in every ocean in the world, and they can also be found in reservoirs high in the Andes.
Dredging is considered to have the potential to have a significant impact on the environment. Whether in the extraction operation or in the relocation stage, attention must be paid to minimize the interference to marine life. In addition, the dredged material should not be simply regarded as waste. The potential for some form of beneficial use of the material must be considered. With the improvement of environmental protection awareness and the strengthening of legislative control, finding suitable locations to relocate the dredged materials may become a major constraint on the implementation of dredging projects.
