Hydraculic System

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.

Dredging System

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.

Electric System

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.

Dredger Spud

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.

Dredger Engine Room

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

Driving Cabin

The river dredger has a main console in the wheelhouse. The components of the console are all miniaturized devices. The internal structure of the console is convenient for maintenance of the front and side of the board, and the panel of the console adopts an openable structure.


Components included in the console:

1. The river dredger console is equipped with AC power distribution unit and DC power distribution unit.

2. The diesel engine control unit of the dredger is located on the control table.

3. Mud pump pressure gauge (mechanical type), vacuum gauge (mechanical type).

4. Pressure gauge for hydraulic equipment (mechanical).

5. The dredger power equipment control unit controls the following equipment:
(1). Emergency pump hydraulic pump
(2). Engine room fan
(3). Shaft seal water pump
(4). Fire pump

6. The dredger control station is equipped with whistle and broadcasting equipment.

Dredger Winch

The winch of river dredger 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.

The main features of the winch are:

1. Small size
2. Lightweight
3. Strong and wear-resistant
4. Anti-corrosion
5. Safe and convenient
6. Fast maintenance

Dredger Body

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.

Dredger Engine

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 river dredger

Dredger Pump

Dredging pump is one of the main working parts of river dredger for sale. 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

1. Design of Mud pump shell

The shell of the double-shell pump is not in contact with the mud and is not subject to wear, so the double-shell pump is much safer than the single-shell pump. With the protection of the outer shell, the inner shell can be fully utilized. At the same time, the use of high wear-resistant materials for the inner shell can greatly extend its service life, reduce the operating cost of the dredger, and improve the safety performance of the cutter dredger.

Submersible pumps are widely used in large-scale projects. On the one hand, the addition of submersible pumps increases the depth of digging and increases the concentration. On the other hand, the combination with the tank pump can increase the discharge distance, making the entire suction and discharge system better Automatic adjustment function, better adaptability to working conditions and higher efficiency

2. The overall design of the mud pump

In the design and selection of the suction pump, we will select reasonable parameters according to various conditions such as the dredging depth, soil condition, output, and discharge distance of the customer's construction project. And determine the best working condition point of the mud pump, so as to make the whole ship have better economy.

For example, if the discharge distance of a certain project is far, if you blindly increase the head of a single pump, it will inevitably increase the power and invest more in single-party costs for future projects that are not of this type.

3. Cost optimization of suction pump

Concentration and efficiency are two very important parameters of the suction pump. It is far more economical to increase the concentration percentage point than to increase the efficiency percentage point of the suction pump.

Cutter Head

The leader Dredger full range of dredger cutter head uses wear-resistant materials, which can meet many harsh dredging and mining environments. The cutter head can cut soil of many different types of materials, such as mud, sand, sandstone, minerals, and hard stones.

Cutter teeth
Our Cutter teeth can be replaced. The blade is equipped with an adapter to easily install and remove Cutter teeth. To meet the requirements of cutting more materials. The design of the blade of the dredge blade can minimize the overflow of the cutter. They introduce the cut material into the nozzle in the most effective way.

Desgin

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.
