Cutter Suction Dredger
The dredging device of Leader Dredger lake dredger is powered by a hydraulic system. The hydraulic system is distributed throughout the dredger and is the core control system of the entire ship. The hydraulic system is a systematic project with strong professionalism and comprehensiveness.
The main hydraulic components include: driving the reamer, driving the bridge frame up and down, controlling the ship to swing left and right through the lateral winch, and controlling the up and down movement of the positioning pile through the positioning pile cylinder. In addition, the trolley and the traveling anchor are also driven by the hydraulic system.
1. The advantages of light weight per unit power, small inertia, fast response, and easy to quickly realize the start of braking
2. The working medium of the hydraulic system has a certain elastic shock absorption capacity, which can make the hydraulic transmission run smoothly and reliably

1. Improve the accuracy of dredging construction: Construction accuracy is necessary for high-end dredgers. It requires the dredger to neither over-dig nor omission during the construction process, and to obtain an accurate excavation profile.
2. Improve construction efficiency: The work efficiency of the dredger directly affects the construction of related projects, and an efficient monitoring system can shorten the construction period.
3. Improve the working conditions of the operators: In the construction of the dredger, the operation steps of the entire process are simplified, the labor intensity of the operators is reduced, and the faults in the excavation process can be quickly found through the alarm display, saving maintenance time
The electrical system of the dredger is composed of a main generator set, a standby generator set, an electrical cabinet, a charger and an operation console.

The spud is mainly used to fix and push the dredger forward. The spud system is composed of a main spud, an auxiliary spud and a hydraulic lifting mechanism.
In Lake Dredger's spud system, the main spud plays a role in positioning during the operation of the dredger. It is inserted in the mud layer. When the dredger moves laterally, it makes a fan-shaped movement around the main spud. , This needs to ensure that the dredger is swinging back and forth on the centerline, so it is very important for the selection of the spud system. It must be ensured that the spud system remains fixed during the swing.
1. Made of high-quality steel with high strength and wear resistance. Customers can also order other materials.
2. Longer service life and easy maintenance.
3. Simple disassembly and assembly, can be accurately adjusted.
Leader Dredger space is far superior to European and American ships, this design is more convenient for good ventilation system and maintenance of cabin components.
Reasonable layout of engine, hydraulic, circuit cold area system, etc., easy to locate and maintain system problems
The Leader Dredger full range of dredging boat Driving cabin has more field of vision, which is convenient for viewing more external conditions.
The extremely simple control system allows the driver to better operate the dredger.
Provide drivers with a high-quality working environment, and equipped with air conditioning.
The hydraulic winch of the cutter suction dredger is mainly a winch with a large rated load, which is driven by a reliable and low maintenance hydraulic motor.
The hydraulic winch of the dredger uses oil as the working medium, transmits motion through the change of the sealed volume, and transmits power through the pressure inside the oil.
There is a production design team inside the factory, which can design the hull according to Chinese standards or BV standards, produce welding, and the painting process is in accordance with the standards of sea ships.
Ensure the high strength and corrosion resistance of the hull, so that the entire ship has a longer service life and stable operation.
Leader Dredger's dredger uses diesel engines.
When we choose the engine brand, we will test the engine performance
1. Matching degree with dredging pump
2. Is the engine power output stable?
3. Continuity of trouble-free operation
4. Fuel consumption
5. Durability
6. Volume and weight
7. After-sales response speed
8. Maintenance costs
A better engine can ensure the practicality, economy and rationality of the cutter dredger
The mud suction pump is the key equipment for lake dredger to transport mud. It is a device that sucks the mixture of soil and water cut by the cutter out of the water. The mud transfer is realized by the suction pump. Its work efficiency directly affects the efficiency of the entire construction.
Leader Dredger lake dredger uses centrifugal suction pumps.
In the dredging process, the suction pump must have a large suction capacity. The equipment for relative movement inside the suction pump mainly includes: liner, impeller and pump casing. Their wear is relatively large, so these components are usually made of wear-resistant materials.
The installation position of the suction pump on the dredger is different, and the suction power is different. Therefore, when designing, Leader Dredger will make the most economical design plan.
The mud suction pump is provided with stable power by the diesel engine
The reamer cutting system includes all devices that move the reamer, cut the soil, and drive the soil to mix with environmental water.
The reamer system is a process in which the reamer is driven by a frequency conversion motor to rotate at a high speed to crush the underwater soil, and with the rotation of the reamer, the mud mixed with the soil and the surrounding water is sucked away by the mud pump.
In the construction process, especially when digging hard soil or silt sand, the cutter teeth wear more seriously. Therefore, the Leader Dredger adopts the design that the cutter teeth and the cutter are separated. After wear, only the cutter teeth need to be replaced, which facilitates the replacement of different cutter teeth according to different soil qualities and minimizes wear.
Regardless of the dredging tool, it plays an extremely important role in the performance of the cutter suction dredger. Therefore, Leader Dredger has extremely high requirements for the selection of cutter heads:
1. Small leakage
2. The inhalation resistance and the possibility of blockage are small
3. Match cutting power with power equipment
4. Made of wear-resistant materials
5. Reamer head produced by floating ring seal technology
6. Hydraulic power drive
6. Fine manufacturing, simple installation, quick replacement
There are 32 people in the technology and design department
12 senior technicians
20 technicians.
Can design and have all kinds of dredgers, civil, warships, marine engineering equipment qualifications.
We can do different types of China Classification Society CCS, American ABS, European BV, Italian RINA standard ships, dredgers, ships, etc.
The design of the cutter suction dredger involves disciplines such as mechanical manufacturing, electrical and electronic, hydrodynamics, computer technology, automation science, materials science, marine meteorology and even nuclear physics, and belongs to the category of system engineering design.
Leader Dredger specializes in analysis and design of dredger hull size, winch bridge, winch system, hydraulic system, positioning pile, mud pump system and its professional design, And repeatedly debug the power system, environment, vibration and noise issues
According to the dredging volume, digging depth index and soil quality of the construction project, the specific performance indexes such as the digging depth, soil breaking capacity and production capacity of the cutter suction dredger are determined.
This design concept is not only widely used in general commercial dredging fields, but also in military, scientific research and engineering fields.
The difference is that dredgers that serve commercial projects can improve the performance of cutter suction dredgers to achieve higher production efficiency and economic benefits, while dredgers used in military and scientific research fields can meet the needs of specific projects. Its economic performance is relatively lower.
In the current economic and social environment, a design that only focuses on technical performance without considering product economic indicators is almost impossible. The cutter suction dredger design is also based on practicality, reliability and other technical indicators, fully considering the economic performance in use, and weighing the unified indicators of technical performance and economic performance to achieve better design results.
