Product Overview

The 8-inch jet-suction dredger offers moderate flow rate and long transport distance, reliably meeting the needs of general river dredging, land reclamation by filling, and sand mining projects. It is a cost-effective solution for small and medium-sized dredging operations. The equipment relies 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 up sediment and sludge from the riverbed, mixing them with water to form a slurry. Using vacuum suction and pressure differentials, the slurry is transported via a suction pipe to the designated location, achieving integrated excavation and transportation. The equipment requires low investment, has a quick return on investment, is easy to operate and can be controlled by one person, is easily disassembled for transport and relocation, and uses wear-resistant materials that keep maintenance costs low. It precisely meets the core needs of small dredging companies, sand mine owners, township water conservancy departments, and fish pond farmers, thoroughly solving the problem of dredging in 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 the jet principle, it quickly stirs up sediment and sludge from the riverbed;

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

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

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