Water Injection Jet suction dredger

China Jet Suction Sand Dredger Hydraulic System Operation

Jet suction dredger equipped with high-pressure water jet ,use of high-pressure water pump to break the cohesion of the soil to be dredged, pump sand out of water and then discharges it to the 

destination by pipeline. Jet suction dredgers is easy to operate and of high efficiency, which is applied for rivers dredging, 

lakes and ponds desilting, land reclamation, ports cleaning and sand mining etc. The dredger is equipped with sand pump 

from 4 inch to 12 inch and the maximum dredging capacity is about 800m3/hr.

1. Design

    Our sand dredging machine are designed by senior engineer, who have specialized in shipbuilding and dredging work for many years, to guarantee they are well-designed and practical.

2. Skilled workers & ex-work testing

     Every cutter suction dredger is built by skilled workers and inspected strictly to assure the high quality and durability. Each finished dredger will be tested in our testing center to make sure it works smoothly when delivering to customers.

3.Cummins Engine

     The dredgers are equipped with world famous powerful Cummins engine, which are famous for its durability, lower oil consumption, standardized accessories and easy maintenance.

4. Hydraulic system

     Hydraulic system: the most important parts of cutter suction dredger and wheel bucket dredger. The hydraulic system requirements are very high and strict; it’s the main artery of the entire dredger. Lateral traction winches, lifting winch and cutter head of the dredgers are driven by hydraulic motors.

     An integral hydraulic system includes hydraulic oil tanks, hydraulic pump, hydraulic valve manifold, solenoid valve, hydraulic pipes, hydraulic components, electrical actuator and so on.

5. Detachable Structure

     The suction dredgers are detachable, so it is easy to transport when delivering or moving from one working site to another.

6. Assembly & Staff Training

     Our experienced installers will arrive at the construction site to guide, teach and training your staff to debug and operate the dredger until they can operate skillfully by themselves.
