As an important equipment of modern dredging engineering, the jet suction dredger plays a key role in river
regulation, port maintenance, offshore engineering and other fields with its unique working principle and significant
technical advantages. The working principle of the jet suction dredger is based on the coordinated operation
of fluid mechanics and mechanics. The ship is equipped with a powerful mud pump and a high-pressure water
pump. During operation, the high-pressure water pump sprays water at high speed to form a strong jet impact
force, which disperses the silt, sand and gravel on the bottom of the water and suspends them in the water;
at the same time, the mud pump generates a strong suction force to suck the mixture of materials and water
dispersed by the jet into the mud suction pipe, and then transport it to the designated location through the mud
discharge pipeline. This combination of jet impact and vacuum suction realizes efficient and continuous excavation
and transportation operations, and can adapt to a variety of complex underwater environments.

sand Pump
The dredge pump is the core component that transports the slurry (a mix of water, sand, and sediment)
through the pipeline. Designed for heavy-duty performance, it handles abrasive materials with high efficiency.
Key features include wear-resistant materials, strong suction capacity, and variable speed control to optimize
production.
The control room is the command center of the dredger, equipped with advanced monitoring and control
systems. Operators use joysticks, touchscreens, and sensors to manage the cutter head, suction pipe,
pumps, and positioning systems (like GPS or DP). Real-time data on depth, pressure, and efficiency ensures
precise and safe dredging operations.
From the core advantages, the suction dredger has extremely high operating efficiency. Its powerful mud pump
and jet system can quickly handle a large amount of earth and stone. Compared with traditional dredging methods,
the dredging volume per unit time has been greatly increased, which can significantly shorten the project cycle.
In terms of adaptability, the ship can flexibly cope with waters of different depths and soil conditions, whether it is
shoals, rivers, or deep sea areas, whether it is soft mud, silt, or medium-hard clay, it can operate effectively. In
addition, the operation of the suction dredger is relatively simple. Through the automatic control system, the
operator can accurately control the direction of the jet, the size of the suction force, and the mud discharge path
to ensure construction accuracy and reduce the difficulty and labor intensity of manual operation.
In terms of technical characteristics, suction dredgers are usually equipped with advanced positioning and
navigation systems, such as GPS, sonar, etc., which can achieve high-precision positioning and real-time
monitoring to ensure construction safety and project quality. At the same time, in order to reduce the impact on
the environment, modern suction dredgers also adopt environmentally friendly designs, such as optimizing the
mud discharge system to reduce mud leakage; equipped with sewage treatment equipment to purify the sewage
generated during the operation, in line with environmental protection standards.
