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.
Dredger electrical cabinet:
It is the electrical equipment for controlling dredgers, including motors, gate blades, backup hydraulic pumps, fans, air switches for lighting and leakage protectors.
On the panel are:
voltage indicator, working/standby generator switch, standby hydraulic pump, sand pump, sealing water pump, miscellaneous water pump, start/stop button of the fan.
Battery for dredger:
Start the diesel engine, solenoid valve of the hydraulic system, 24v power supply lighting of the whole dredger, to provides the power.
Anchor rod system
Flowmeter, concentration meter
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.
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.
There are 32 people in the technology and design department
12 senior 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.
