What’s the working principle of Submersible Pump Dredger and Usage?
Submersible pump dredgers play a vital role in various dredging projects, as well as sand and mining extraction. This comprehensive article aims to provide a detailed analysis of the working principle of submersible pump dredgers, including their structure, advantages, disadvantages, cost considerations, and application scenarios. By exploring and comparing these aspects, it will offer professional recommendations for selecting the most suitable equipment.
1. Dredger Structure
A submersible pump dredger is equipped with a submersible slurry pump and typically consists of the following components:
1.1 Submersible Slurry Pump:
The submersible slurry pump, also known as a submersible dredge pump, is a core component of the dredger. It features a unique coaxial configuration that combines a motor, mechanical pump, and bottom agitator, enabling efficient mixing of sand, mud, and sludge. This design allows for the transportation of high-concentration materials without the need for water injection, simplifying operations in underwater environments.
OCEAN Pumps, specifically designed for industries such as metallurgy, mining, and thermal power plants, excel in extracting liquids containing solid particles like sand, cinder, and tailings. The submersible dredge pumps are typically centrifugal dredge pumps, available in electrical or hydraulic types.
1.2 Power System:
The power system is selected based on the dredge pump requirements. Firstly, a generator or hydraulic power pack is chosen according to the pump type. Secondly, Tai’an OCEAN Pump’s engineers calculate the power needed by all the devices and determine the power requirements for the dredger. Finally, they suggest stable engine brands or cater to customers’ preferred brands.
1.3 Winches:
Winches include the pump hoist winch and anchor winches. The pump hoist winches can be electrical or hydraulic, depending on the dredger design. The winch capacity is determined by considering the weight of the pump, cables, and hoses. Anchor winches can be manual, hydraulic, or electrical. Smaller dredgers typically opt for manual winches to control costs, while larger sand dredgers often choose electrical or hydraulic winches for ease of operation.
1.4 Dredger hull, pipeline, and control system：
After selection of the core parts, the engineer will take into account the parameters of each device, design the size of the ship based on weight and stability requirements. In addition, design the pipeline layout based on the flow rate and head of the pump.
2. Features
2.1 Advantages:
2.1.1 Easy Operation:
Submersible pump dredgers can access areas that are challenging for other types of dredging equipment to reach. Their design allows for enhanced maneuverability and navigation in confined spaces.
2.1.2 Precise Control:
Submersible pump dredgers offer better control over the dredging process, enabling precise removal of sediment. Operators can accurately target specific areas and depths, facilitating efficient dredging operations.
2.1.3 Portability:
Compared to large dredging vessels, submersible pump dredgers are smaller in size, making them easily transportable. They are particularly suitable for small-scale projects or areas with limited space.

2.1.4 Low Noise:
As the submersible slurry pump operates underwater, the working environment noise is relatively low compared to other dredging methods. This feature helps minimize disturbances in sensitive areas or urban environments.
2.1.5 Deep Water Extraction:
With technological advancements, OCEAN submersible slurry pumps can reach depths of over 100 meters. Therefore, in environments with significant water depths, submersible pump dredgers from Tai’an OCEAN Pump prove to be an economical and effective choice for extracting sediment.
2.1.6 Multifunctionality:
Submersible pump dredgers can be employed in various applications, including the maintenance of small waterways, ponds, and lakes, as well as sand extraction from the sea. Their versatility makes them suitable for a wide range of dredging and sediment removal tasks.
2.2 Disadvantages:
2.2.1 Handling Large Amounts of Sediment:
Submersible pump dredgers might have limitations in handling large volumes of sediment compared to larger dredging vessels. However, they are still highly effective in smaller-scale projects and localized dredging tasks.
2.2.2 Handling Large Pieces of Material:
When encountering larger debris or solid objects, submersible pump dredgers may face difficulties in their handling. These dredgers are primarily designed for extracting sediment and sludge, rather than robust objects.
3. Applications
Submersible pump dredgers find applications in various scenarios, including:
4. Why Choose Submersible Pump Dredgers from Tai’an OCEAN Pump?
