Product Overview

The 10-inch jet-suction dredger boasts powerful performance and great suction depth, making it the preferred equipment for medium-sized river channels, port dredging, and large-scale sand mining operations, delivering outstanding overall benefits. Relying on the jet principle, the machine uses a high-pressure water pump to generate a high-pressure water flow, which is then ejected at high speed through nozzles to create a negative pressure zone. This draws bottom sediments and sludge into a slurry, which is subsequently conveyed via a suction pipe to a designated location, achieving integrated excavation and transport. With its combined jet-suction design, this equipment is less prone to pipe blockages, maintains stable operational efficiency, and can handle slurry concentrations of 30%–40%. Its hull offers excellent stability, adapting to various working conditions and precisely meeting the core needs of medium-sized engineering firms, sand and gravel enterprises, port maintenance units, and municipal engineering companies, effectively addressing key pain points in medium-sized dredging and sand mining projects.

Working Principle

1. The high-pressure water pump delivers robust power, generating a high-pressure water flow that is rapidly ejected through a dedicated nozzle, creating a stable negative pressure zone at the suction inlet. Utilizing the fluid dynamics of jet propulsion, it efficiently stirs up deep-layer sediments and sludge at the bottom of the water body;

2. The combined action of negative suction and pressure differential thoroughly mixes deep-layer sediments and sludge with water, forming a uniform slurry with a concentration of 30%–40%. The integrated jet-suction design prevents pipe blockages, ensuring continuous operation;

3. The slurry is steadily drawn through a high-strength suction pipe, leveraging strong power to achieve long-distance transport without requiring additional auxiliary equipment, thus completing efficient integrated excavation and conveyance;

4. The hull’s stability has been optimized, enabling adaptation to shallow waters, port shoals, and other diverse working conditions, preventing grounding while also allowing adjustment of suction depth to meet the varied demands of medium-sized projects.
