Detailed Photos

          A cutter suction dredger is a dredging tool that uses a rotating cutter to loosen the soil on the riverbed or seabed, mixes it with cement to form mud, and then sucks the mud into the pump body through a suction pipe and sends it to the discharge area. It is mainly used for dredging in inland lake areas and coastal ports, suitable for excavating soil such as sand, sandy loam, and silt. During the construction of the cutter suction dredger, the dredging, transportation, and unloading processes can be completed continuously in one go, resulting in high production efficiency.
The main structure of a cutter suction dredger includes the hull, cutter, suction pipe, pump body, and discharge pipe. The cutter is a key component of a cutter suction dredger, usually installed at the bow or side of the ship. By rotating the cutter, the sediment at the bottom of the water is crushed and mixed with water to form mud. The suction pipe is used to suck mud into the pump body, which transports the mud to the discharge area through the discharge pipe.

 

 
 To troubleshoot and solve faults in the power system of a fully hydraulic dredger, the following steps can be followed:

1. Fault observation and information collection
-The operator provides a detailed description of the malfunction, including any abnormal sounds, vibrations, slow or ineffective movements that may occur.
-Check for abnormal changes in parameters such as pressure, flow rate, and temperature on the dashboard.

2. Appearance inspection
-Check for leaks in hydraulic pipelines, including connections, cylinders, valve groups, and other parts.
-Check for obvious damage, deformation, cracks, etc. in the components.

3. Hydraulic oil inspection
-Observe the color, odor, and transparency of hydraulic oil to determine if it is contaminated, spoiled, or mixed with water.
-Check if the liquid level is normal.

4. Stress testing
-Measure the pressure of key parts of the system using a pressure gauge and compare it with normal working pressure to determine if there is insufficient or excessive pressure.

5. Action testing
-Operate each actuator separately, such as oil cylinders, hydraulic motors, etc., and check whether their actions are normal and whether their speeds meet the requirements.

6. Component troubleshooting
-Inspect the main components such as the oil pump, hydraulic valve, oil cylinder, and motor in sequence.
-For the oil pump, its working sound, temperature, and oil output can be checked.
-For hydraulic valves, check the flexibility and sealing of the valve core.

7. Cleaning and replacing components
-Clean any components found to be contaminated, such as filters, valve cores, etc.
-Replace seals, filters, valves, etc. that are worn, damaged or aged in a timely manner.

8. Circuit and control system inspection
-Check if the electrical connection is good and if the sensor signal is normal.
-Check if the settings and program of the controller are correct.

9. Debugging and trial operation
-After completing maintenance or replacing components, perform system debugging, gradually increase the load, and observe the operation of the system.
-Ensure that the fault has been completely resolved and the system is working properly.

For example, if a certain actuator of a dredger is found to be sluggish, first check whether the hydraulic oil pressure is normal. If the pressure is insufficient, it may be due to oil pump failure or valve leakage. Then inspect the oil pump. If the oil pump is functioning properly, check the relevant valve components, locate the leaking valve components, and replace the seals. After the maintenance is completed, conduct a trial run to confirm that the action has returned to normal.

For some complex faults, it may be necessary to rely on professional testing equipment and experienced technicians for accurate diagnosis and repair.
 

The construction process of a cutter suction dredger is generally as follows:
1. Construction preparation: including the formulation of construction plans, survey of construction areas, equipment inspection and commissioning, etc., then positioning the ship and accurately positioning the cutter suction dredger in the construction area. According to the wind and flow conditions, set up the windward and upstream anchors in order to stabilize the ship's hull.
2. Lowering the cutter bridge: Lower the cutter bridge to the designated cutter position for excavation.
3. Soil conveying: The soil crushed by the cutter is transported to the designated mud receiving area through a high-power centrifugal mud pump and a discharge pipeline.
4. Construction monitoring: Real time monitoring of excavation depth, instantaneous water level, cross-sectional view of excavation trench or underwater three-dimensional map and other data to ensure construction quality and safety.
5. Moving ship position: According to construction needs, move the ship to the next construction area by retracting and releasing anchor cables and adjusting the position of the winch.
The specific construction process may be adjusted appropriately based on engineering requirements, soil quality, hydrology, and other factors. topic

Choosing the appropriate engine power for a dredger requires comprehensive consideration of multiple factors:

**1.  Dimensions and types of dredgers * *:
-Large dredgers typically require higher power engines to drive their massive equipment and systems. For example, self-propelled cutter suction dredgers require high power due to their complex dredging and conveying systems.
-Small dredgers, on the other hand, require lower power engines.

**2.  Working environment and conditions * *:
-If working in areas with turbulent water flow, deep water, or hard soil, greater power is required to overcome resistance and excavation difficulties. For example, dredgers operating in the deep sea require high-power engines due to water pressure and complex seabed geology.
-On the contrary, operating in relatively calm and soft soil areas requires relatively less power.

**3.  Dredging methods and efficiency requirements * *:
-Different dredging methods, such as cutter suction, rake suction, grab bucket, etc., have different power requirements. The cutter suction dredger usually requires higher power to drive the cutter and mud pump.
-If there is a high demand for dredging efficiency, such as the need to complete a large number of dredging tasks in a short period of time, a higher power engine is required.

**4.  Pumping distance and height * *:
-When it is necessary to transport excavated sediment to a longer distance or higher location, the pumping system requires greater power, which also requires the engine to have higher power output.

**5.  Auxiliary equipment for ships * *:
-In addition to dredging equipment, auxiliary equipment such as lighting, ventilation, and air conditioning on board also consume a certain amount of power. When calculating engine power, these factors need to be taken into account.

For example, a medium-sized cutter suction dredger plans to operate in a river with fast water flow and medium soil hardness, and is required to complete a certain amount of dredging tasks every day, while transporting sediment to a designated location 1 kilometer away. By comprehensively evaluating and calculating these factors, the power range of the required engine can be preliminarily determined.

For example, a small grab dredger that mainly operates in shallow water areas and soft soil ponds does not require high dredging efficiency, and its required engine power will be relatively small.

In actual selection, it is also necessary to refer to relevant industry standards, empirical data, and recommendations from engine manufacturers to ensure that the selected engine power can meet the operational needs of the dredger, while avoiding waste and cost increase caused by excessive power.
