Product Overview

The 8-inch jet-suction dredger features moderate flow rate and long delivery distance, reliably meeting the needs of general river channel dredging, land reclamation through hydraulic filling, and sand mining projects. It is a cost-effective solution for small- and medium-sized dredging operations. Relying on the jet principle, the equipment uses a high-pressure water pump to generate a high-pressure water stream, which is ejected through a nozzle to create a negative pressure zone. This draws bottom sediments and sludge into a mixture with water, forming a slurry. Then, utilizing vacuum suction and pressure differentials, the slurry is conveyed via a suction pipe to a designated location, achieving integrated excavation and transportation. The equipment requires low investment, offers rapid return on investment, is easy to operate—can be controlled by a single operator—and is conveniently disassembled for transport and relocation. Made from wear-resistant materials, it also boasts low maintenance costs, precisely addressing the core needs of small dredging companies, sand mine owners, township water conservancy departments, and fish pond farmers, thoroughly solving the challenge of dredging in narrow waterways.

Working Principle

1. After the high-pressure water pump starts, it generates a high-pressure water stream that is rapidly ejected through a dedicated nozzle, creating a negative pressure zone at the suction inlet. Leveraging the fluid dynamics of jet propulsion, this quickly stirs up bottom sediments and sludge;

2. The vacuum suction created by the negative pressure zone works in tandem with the pressure differential to thoroughly mix sediments and sludge with water, forming a uniform slurry and preventing clumping that could impede smooth conveyance;

3. The slurry is precisely drawn through the suction pipe, relying on the equipment’s stable power to achieve long-distance transport without additional auxiliary equipment, thus completing integrated excavation and transportation;

4. The equipment allows flexible adjustment of the working angle to accommodate varying water depths and supports on-demand adjustments to the delivery distance, balancing operational flexibility with stability.
