Product Overview

The 8-inch jet-suction dredger features moderate flow rate and long delivery distance, reliably meeting the needs of general river dredging, land reclamation by hydraulic filling, and sand mining projects. It is a cost-effective solution for small and medium-sized dredging operations. The equipment operates on the jet principle: a high-pressure water pump generates high-pressure water flow, 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. Subsequently, vacuum suction and pressure differentials transport the slurry through a suction pipe to the designated location, achieving integrated excavation and transportation. With low investment and quick return on investment, simple operation allowing single-person control, convenient disassembly for transport and relocation, and low maintenance costs due to wear-resistant materials, this equipment precisely addresses the core needs of small dredging companies, sand mine owners, township water conservancy departments, and fish pond farmers, effectively solving the challenge of cleaning narrow waterways.

Working Principle

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

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

3. The slurry is precisely sucked up through the suction pipe, relying on the stable power of the equipment to achieve long-distance transportation without additional auxiliary devices, thus completing integrated excavation and transportation.

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