Cutter Head Dredge Hydraculic System

The hydraulic system of the Leader dredger 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 complete hydraulic system of cutter head dredge for sale consists of five parts, namely power components, executive components, control components, auxiliary components (accessories) and hydraulic oil.

1. Power components

The function of the power element is to convert the mechanical energy of the prime mover into the pressure energy of the liquid, which refers to the oil pump in the hydraulic system, which provides power to the entire hydraulic system. The structure of hydraulic pumps generally includes gear pumps, vane pumps, plunger pumps and screw pumps.

2. Actuator

The function of the executive components (such as hydraulic cylinders and hydraulic motors) is to convert the pressure energy of the liquid into mechanical energy, and drive the load for linear reciprocating or rotary motion.

3. Control components

Control elements (ie various hydraulic valves) control and regulate the pressure, flow and direction of the liquid in the hydraulic system. According to different control functions, hydraulic valves can be divided into pressure control valves, flow control valves and directional control valves. Pressure control valves include relief valves (safety valves), pressure reducing valves, sequence valves, pressure relays, etc.

Flow control valves include throttle valves, regulating valves, and diverting and collecting valves; directional control valves include one-way valves, hydraulically controlled one-way valves, shuttle valves, reversing valves, etc. According to different control methods, hydraulic valves can be divided into on-off control valves, fixed value control valves and proportional control valves.

4. Auxiliary components

Auxiliary components include fuel tanks, oil filters, coolers, heaters, accumulators, oil pipes and pipe joints, sealing rings, quick-change joints, high-pressure ball valves, hose assemblies, pressure measuring joints, pressure gauges, oil level gauges, oil Thermometer etc.

5. Hydraulic oil

Hydraulic oil is the working medium that transfers energy in the hydraulic system. There are various types of mineral oil, emulsion and synthetic hydraulic oil.

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.

In order to improve the power supply efficiency of the cutter head dredge power station and ensure the safety, stability, balance and continuous power supply of the whole ship, the dredger power station is equipped with a set of power management system for the whole ship's electrical system according to the requirements of fully automatic management design.

(1) Separate the main high-power equipment from the ship's sensitive equipment, such as generators, transformers, frequency converters and motors.

(2) Adopt isolation and filtering measures for the auxiliary power supply used by the electric propulsion system equipment to avoid using the same power supply with sensitive electronic equipment.

(3) The power generation equipment on the ship, the motor base and shell, the shell of the switchgear box, the exposed metal lighting, the metal appearance and shielding layer of all cables, etc. will be grounded, and the metal grounding conductor is connected to the hull to achieve the minimum ground resistance. the goal of


Advantages of electric system

(1) Good economy and high efficiency.
(2) High reliability, high degree of automation, and good operability.
(3) Low noise and low vibration.
(4) Wide range of speed regulation, large driving force, easy forward and reverse rotation, volume Small size, flexible layout and easy installation.
(5) Low emission and environmental protection.

Optional Items

Service boat

Dredge Spud

Two positioning piles are arranged symmetrically on the left and right sides of the stern of dredge. When dredging, the two positioning piles on the left and the right are inserted and pulled out of the soil in turn, so that the hull moves forward.

According to the dredge size, digging depth, working area and reamer power, the size and type of positioning piles are also varied.


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.

Dredge 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 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.

Dredger Winch

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.

Dredge Body

1. The whole ship adopts an assembled design to facilitate road transportation, which expands the scope of use of dredgers. The upper part of the pontoon is connected by bolts, and the lower part is connected by connecting blocks. The manufacturing and assembling precision of such connecting blocks is required to be high.

2. The hull frame beam is basically made of section steel. Section steel can save a lot of welding and straightening time, and at the same time improve the quality of the beam, which is very important for the quality of the cutter head dredge.

Dredge Engine

The engine used by cutter head dredge can undergo a series of precise controls to inject fuel into the combustion chamber through the unit pump;

Control the combustion process by adjusting the fuel injection timing and fuel quantity in real time;

Match the engine output with the work needs with the highest efficiency.

Dredge Pump

Leader Dredger's full range of dredgers use Chinese professional pump manufacturers. And we will change the number of pumps according to the discharge distance and dredging depth, so as to provide stronger suction for the dredger.
Leader Dredger can be customized according to working conditions.

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.

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.
