Cutter Suction Dredger
Leader Dredger's 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 are: driving the reamer, driving the bridge up and down, controlling the ship to swing left and right through the traverse winch, and controlling the positioning pile up and down through the positioning pile cylinder. In addition, the trolley and the running anchor are also driven by the hydraulic system.
The advantages of the hydraulic system include: light weight per unit of power, small inertia, fast response speed, and easy start and stop. The working medium of the hydraulic system has a certain elastic shock absorption capacity, which can make the hydraulic transmission system operate stably and reliably. These advantages just meet the working requirements of the working mechanism of cutter suction dredger. Judging from the current mainstream design, hydraulic transmission is the main transmission method adopted by the dredger dredging equipment.
The dredging system is divided into a control system and a monitoring system, which is a highly integrated system.
Through the monitoring system, you can understand the working status of all components of the whole ship, the working status of the main and auxiliary engines, the real-time status of the hydraulic system, the condition of the electrical circuit system, the running status of the pump, the working status of the gear box, the cooling system, etc.
At the same time, the centralized control unit controls the working parts of the dredger in real time through the operation lever and the like. One person can operate the parts of the entire ship.
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.
Among them the main generator set:Provide power for sealing water pumps, miscellaneous water pumps, lighting and air conditioning during dredger work.

The lower end of the full range of Leader Dredger dredger spud is made of solid steel to ensure sufficient strength when penetrating the ground. When lifting the pile head, water can overflow from the two holes above the lower point. At the top, the hoist ring allows the crane to easily change the pile head.
Feature:
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 dredging machine designed the dredger driving cabin as an integral detachable type. After disassembly, the maximum height of the dredger can be lowered, which improves the passage of the whole ship.
The connecting pipes and connecting lines between the dredger driving cabin and the engine room and deck are all designed for easy disassembly and assembly of joints to ensure that the dredger can easily disassemble and install the entire cab as a whole when passing a low bridge tunnel, which improves dredging. Practicality of the boat
Leader Dredger equips the driving cabin with more area of tempered glass, which is convenient for the driver to observe the surrounding situation while driving the dredger
The dredging machine driving cabin is equipped with diesel controller, suction pump pressure gauge, vacuum gauge, hydraulic equipment pressure gauge, etc., which can control the dredging system of the whole ship in the driving cabin
The operating system in the driving cabin has been tested by Leader Dredger for many years and has now achieved the advantages of simple operation, intuitive parameters and strong comfort.
The winch of dredging machine adopts hydraulic transmission.
According to the location and function of the dredger, the working winch is divided into the bridge hoisting winch, the left and right lateral shifting working winch, the anchoring winch, and the positioning pile hoisting winch.
Various working winches can be steplessly adjusted within a certain rope speed range, and are equipped with manual stop pins.
1. Small size
2. Lightweight
3. Strong and wear-resistant
4. Anti-corrosion
5. Safe and convenient
6. Fast maintenance
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 dredging equipment 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
Dredging pump is one of the main working parts of cutter dredger. It is a device that sucks the mixture of soil and water cut by the reamer out of the water surface, and realizes the transfer of the earthwork through the suction pump. Power consumption generally accounts for 60% to 70% of the energy supply of the whole ship, and its working characteristic parameters roughly represent the performance of the dredger
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.
Large dredge adopts the design of two suction dredge pumps. The underwater pump alone provides stable suction for the reamer. Another dredge suction pump in the cabin is used to strengthen the suction to meet deeper dredging depth or farther discharge distance.
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.
