YSCSD250 Dredger/Suction Dredger with dredging depth of 10 meters

Product description

A sand dredger, also known as a dredger or dredger, is an engineering vessel that uses powerful pumping power to

extract sand, mud, gravel, and other materials from the underwater world. It is a core piece of equipment in the dredging

and mining industries.
1. Core Operating Principle: Centrifugal Pumps and the Siphon Effect
The core of a sand dredger is a high-power centrifugal pump. Its basic operating principle can be summarized as follows:

Vacuum Generation: When the centrifugal pump is started, the high-speed rotation of the impeller expel air from the pump

chamber and the suction pipe, creating a vacuum (negative pressure).
Suction of Material: Under the influence of atmospheric pressure and water pressure, the sand and water mixture on the

underwater surface is forcibly forced into the pump through a large suction pipe (sand suction head), filling the vacuum.
Discharge: The sand and water mixture is imparted with kinetic energy by the pump's impeller and transported through

the discharge pipe to a designated location, such as another barge, a shore dump, or a landfill.

The above technical parameters are for reference only,specific device configuration depends on the conditions of each

project,customer and technical requirements.

Main Application Scenarios
Sand dredgers have a wide range of applications, extending far beyond simply pumping sand:

Dredging: This is the most core application. It removes silt and sediment from ports, waterways, and rivers, deepens waterways,

and ensures safe navigation for large vessels.

Land Reclamation: This is a highly cost-effective application. Sand is extracted from the underwater world and transported

via pipelines to low-lying areas near the coast or coast, creating new usable land. For example, large-scale projects such as

the Palm Islands in Dubai, Shanghai Pudong Airport, and Shenzhen Qianhai have all made extensive use of sand dredgers.

Sand Mining: Construction and industrial sand is extracted from riverbeds, lakebeds, or the seabed, making it a vital source

of building materials.

Environmental Protection and Water Conservancy Projects:

Reservoir Desilting: Restores reservoir capacity and function.

Lake Management: Removes contaminated sediment and improves water quality.

Dyke Reinforcement: Extracts sand for use in river and seawall reinforcement. Mining operations: Used to mine underwater

precious minerals such as diamonds, tin, gold, etc. (in this case, it is called a "mining ship").

Summary: Sand dredgers are powerful engineering vessels that transform underwater topography and coastlines through their

efficient pumping systems. They are not only a critical tool for dredging waterways and ensuring navigation, but also a modern

machine for expanding land and acquiring resources. They play an indispensable role in global infrastructure development,

resource development, and environmental governance.
