Product Overview

The 14-inch jet-suction dredger features a high-flow, high-lift design, enabling long-distance transport and making it the preferred equipment for large-scale river dredging, port construction, and land reclamation projects. The machine relies on the jet principle: a high-pressure water pump generates a high-speed water flow that is ejected through a nozzle, creating a negative pressure zone. This draws up sediment and sludge from the riverbed, mixing them with water to form a slurry. Using vacuum suction and pressure differentials, the slurry is conveyed through a suction pipe to the designated location, achieving integrated excavation and transport operations. With its exceptional suction capacity, this equipment can adapt to complex geological conditions. Its robust hull offers excellent resistance to wind and waves, while its modular design ensures quick installation, precisely meeting the core needs of professional dredging groups, large infrastructure companies, and overseas engineering contractors, effectively addressing the challenges of tight deadlines and difficult construction in large-scale projects.

Working Principle

1. A powerful high-pressure water pump delivers strong energy, producing a high-flow, high-pressure water stream that is rapidly ejected through a specialized nozzle, forming a high-intensity negative pressure zone at the suction inlet. Leveraging the fluid dynamics of jet propulsion, it efficiently stirs various types of sediment and sludge at the riverbed, adapting to complex geological conditions;

2. Negative pressure suction and pressure differentials work in tandem to thoroughly mix sediment and sludge with water, forming a uniform slurry. Thanks to its high-flow, high-lift design, it enables stable long-distance transport without the need for additional boosting equipment, satisfying the demands of large-scale engineering projects;

3. The vessel’s robust structural design provides outstanding resistance to wind and waves, allowing stable operation even in challenging waters, thus preventing disruptions to work progress and safety;

4. The modular design optimizes component assembly and disassembly, enabling rapid installation and significantly reducing equipment preparation time, helping projects get off the ground quickly.
