The working principle of the suction-type sand pumping ship is to use a high-pressure water pump to generate pressurized water, and use a high-pressure water gun to impact the silt. After the water is humidified, disintegrated and flowed, the deposited silt is formed into mud. Then the silt is transported to the operation area through the sand pumping pump and pipeline. It is widely used in rivers, lakes, seas, reservoirs, sand extraction, filling construction, sand pumping and dredging, port river dredging, etc. It has played an important role in the Yellow River machine siltation and embankment consolidation, port dredging, coastal reclamation, and sand pumping and filling projects.
1.Composition of the Jet suction dredger:
1.1 Sand pumping components mainly composed of sand pumps: including sand pumps, sand pump power (diesel engine or motor), high-pressure water pumps, high-pressure water pump power, matching brackets, faucets, and if it is a diesel engine, there is also an auxiliary fuel tank room.
1.2. Auxiliary devices mainly for hull fixation and movement: The hull is fixed by a winch in conjunction with an anchor. The hull movement can be a mobile winch, and sometimes a propeller is used for movement.
1.3. Pipeline system: including sand suction pipes, sand delivery pipes, pipeline floating devices (floating plates or buoys), etc.
1.4. Other auxiliary components: including some rest rooms for workers to rest or cabins for placing sand pumping equipment.
Suction dredgers are widely used in sand pumping and dredging in various environments due to their flexibility, low investment, and high cost performance.
- Jet suction dredgers perform dredging operations by spraying and sucking mud. The following is the working principle of Jet suction dredger:
2.1 Jetting action: Jet suction dredger sprays seawater or clean water to the bottom of the silt or mud layer by spraying water. This process can use a high-pressure water pump to spray water to the bottom to form an underwater high-pressure water column to help loosen and stir the silt layer on the seabed.
2.2 Mud suction: While spraying water, the Jet suction dredger sucks the stirred silt, sand and water into the sludge suction pipe inside the hull through the corresponding sludge suction equipment. Usually, the Jet suction dredger is equipped with a vacuum pump or a centrifugal pump and other equipment for sucking silt and water.
2.3 Transportation and treatment: The sucked sludge and water mixture is transported to the separation device inside the hull through the sludge suction pipe, such as a centrifugal separator or filter, for separating water and solid particles. The water will be discharged back to the water area, while the solid particles will be collected and can be processed or unloaded through the conveying pipe or other means.
2.4 Cyclic operation: During the working process, the Jet suction dredger will cycle through operations such as spraying, sludge suction, separation and water discharge to continuously clean up silt, sand and debris and keep the waterway unobstructed.
Through this working principle, Jet suction dredger can efficiently clean up silt, sediment and debris in the water area, ensuring the smooth flow of waterways and the smooth progress of water projects
- Application of Jet suction dredger
Jet suction dredgers are a commonly used hydraulic machinery equipment used for dredging, dredging, dredging rivers, ports and waterways and other water projects. The following are some applications of Jet suction dredger:
3.1 River dredging: Jet suction dredgers can be used to clean up silt, sediment and other debris in the river channel to ensure the smooth flow of waterways and prevent floods and sediment accumulation.
3.2 Port maintenance: Jet suction dredgers are often used for the maintenance of ports and waterways, cleaning up silt at the entrance and exit of ports, and ensuring the safe passage of ships.
3.3 Submarine pipeline laying: In the submarine pipeline laying project, Jet suction dredgers can be used to dig the seabed to provide a clean and flat bottom bed for pipeline laying.
3.4 Land reclamation: In land reclamation projects, Jet suction dredgers can be used for dredging and reclamation, expanding the land area, and building ports, docks and other facilities.
3.5 Mineral mining: Jet suction dredgers can also be used for underwater mineral mining, such as mining of seabed metal mines, sand and gravel.
Jet suction dredgers are widely used in water conservancy projects, port projects, marine projects and other fields. They can efficiently clean up silt and sediment in water areas and ensure the smooth progress of water projects.
- Why use a Jet suction dredger?
Jet suction dredgers have many advantages and application values, so they are widely used in water conservancy projects, port projects and marine engineering. Here are some reasons for using Jet suction dredger:
4.1 Efficient cleaning of waterways: Jet suction dredgers can efficiently clean silt, sand and debris in waterways, ensure the smooth flow of waterways, and prevent floods and traffic obstructions caused by siltation in waters.
4.2 Flexibility: Jet suction dredgers are suitable for various water environments, including rivers, lakes, ports and oceans, and have flexible operating performance and adaptability.
4.3 Cost saving: Compared with traditional mechanical dredging methods, Jet suction dredgers are usually more efficient, which can save manpower and time costs and improve the efficiency of dredging operations.
4.4 Protect the ecological environment: Jet suction dredgers can accurately clean the target area in the waterway, reduce interference and damage to the surrounding ecological environment, and help protect the balance of the water ecosystem.
4.5 Applicable to a variety of projects: Jet suction dredgers are not only suitable for waterway dredging, but also can be used in various water engineering and marine engineering fields such as port maintenance, submarine pipeline laying, and land reclamation.
4.6 Improve work safety: Compared with traditional dredging methods, the use of Jet suction dredgers can reduce the risk of direct contact with silt and sand and improve work safety.
In summary, Jet suction dredgers have the advantages of high efficiency, flexibility, cost saving, and environmental protection, so they are widely used and adopted in various water projects.
