Product Overview

The 10-inch jet-suction dredger boasts powerful performance and deep suction capability, making it the preferred equipment for medium-sized river channel and port dredging as well as large-scale sand mining operations, delivering outstanding overall benefits. The equipment relies on the jet principle: a high-pressure water pump generates high-pressure water flow, which is ejected at high speed through nozzles to create a negative pressure zone. This draws bottom sediments and sludge into a slurry mixed with water, then utilizes vacuum suction and pressure differentials to transport the mixture via a suction pipe to a designated location, achieving integrated excavation and transportation. With its combined jet-suction design, this equipment resists pipe blockages, ensures 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. A high-pressure water pump delivers robust power, generating high-pressure water flow that is rapidly ejected through specialized nozzles, creating a stable negative pressure zone at the suction inlet. Leveraging fluid dynamics and the jet principle, it efficiently stirs up deep-layer sediments and sludge from the riverbed;

2. Negative pressure suction and pressure differentials work in tandem to thoroughly mix 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, propelled by strong power to achieve long-distance transportation without additional auxiliary equipment, completing efficient integrated excavation and delivery;

4. Optimized hull stability allows adaptation to shallow waters, port shallows, and other diverse working conditions, preventing grounding while also enabling adjustable suction depths to meet the varied demands of medium-sized projects.
