Product Description

       When choosing a dredger, both the quality and price of vulnerable parts are important, and it cannot be simply said which is absolutely more important.

The importance of the quality of vulnerable parts is self-evident. High quality vulnerable parts mean longer service life, fewer failures and maintenance frequencies, which can ensure stable and continuous operation of the dredger, reduce downtime and production losses caused by damage to vulnerable parts. In the long run, it is crucial to ensure the overall efficiency and efficiency of the dredger.

And the price cannot be ignored. A reasonable price can make procurement costs more economical, especially for some budget limited situations where price factors need to be considered to a certain extent to ensure the overall economy of the project.

In an ideal situation, it is necessary to seek a more reasonable price while ensuring a certain level of quality, in order to achieve a balance between quality and price. At the same time, it is necessary to comprehensively consider various factors such as the overall performance, manufacturer reputation, and after-sales service of the dredger. It is not only necessary to focus on the quality or price of vulnerable parts, but also to conduct a comprehensive evaluation and balance to choose the most suitable dredger.

          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.

The advantages of a cutter suction dredger include high construction efficiency, low operating costs, simple operation, and the ability to adapt to different types of sediment. However, it also has some limitations, such as difficulty in construction in high wind and wave areas, making it more suitable for working in inland rivers and lakes. Dredgers can excavate depths of 6-18 meters underwater and transport distances of up to 4-3000 meters.

 

 

The construction process of the cutter suction dredger is generally as follows:
1. Construction preparation: including the formulation of construction plans, measurement of construction area, equipment inspection and commissioning, etc.
2. Ship positioning: Using the DGPS positioning system, accurately locate the cutter suction dredger at the starting point of excavation in the construction area.
3. Set up side anchors: Based on the airflow situation, set up headwinds and headwinds anchors to stabilize the hull.
4. Lowering the knife bridge: Lower the knife bridge to the designated cutting position for excavation.
5. Transportation: Use a high-power centrifugal mud pump and discharge pipeline to transport the soil crushed by the cutting machine to the designated mud receiving area.
6. Mobile vessel position: According to construction needs, move the vessel to the next construction area by retracting and releasing anchor cables and adjusting the winch position.

The following are the daily maintenance and precautions for dredgers:

Daily maintenance:
1. Regularly clean the hull, remove any attached debris, marine organisms, etc., and keep the surface of the hull clean.
2. Inspect and maintain various mechanical components, such as the cutter system, mud pump, engine, etc., to ensure their normal operation. Add lubricating oil and replace vulnerable parts as required.
3. Inspect and maintain the electrical system to ensure the safety and reliability of the circuit and the normal operation of electrical equipment.
4. Check and maintain the hydraulic system to ensure that there are no leaks in the hydraulic components, the hydraulic oil is clean and at the appropriate level.
5. Inspect and maintain the pipelines, valves, etc. of the dredger to prevent leakage and blockage.
6. Regularly inspect and calibrate various instruments and sensors to ensure accurate data.

Notes:
1. Strictly follow the operating procedures to avoid equipment damage or safety accidents caused by misoperation.
2. Pay close attention to the water depth and flow of the construction water area to ensure the safety of the dredging operation.
3. Pay attention to the operation status of the equipment, and if any abnormalities are found, stop the machine for inspection and handling in a timely manner.
4. Provide training and management for crew members, improve safety awareness and operational skills.
5. Ensure that safety equipment such as firefighting and lifesaving are complete and effective on board.
6. Reasonably arrange the operation time and intensity of the dredger to avoid excessive use.
7. Regularly conduct comprehensive inspections and maintenance on the dredger, and record the maintenance status.
