Advantages and Characteristics of HANSEL Cutter Suction Dredger (Epi 1)
Hansel Marine is a leading Chinese manufacturer of Cutter Suction Dredger (CSD). Distinguished from some other Chinese manufacturers, HANSEL is a shipyard with rich experiences in building kinds of marine vessels, which makes HANSEL very familiar and adaptable to the shipbuilding standard, rules, and regulations. Cutter Suction Dredger characteristics and [...]
Construction combination of large and special projects
How to choose construction combination Large projects can be divided into several construction sections with different construction conditions, and they need both excavation and filling, according to the characteristics of the above construction composition, choose the appropriate combination of construction, such as approach channel select self-propelled trailing suction hopper dredger, [...]
Construction combination for the purpose of excavation
1.Water depth of construction areas On navigable rivers, vessels frequent traffic, or there are large wind waves on the approach channel of the seaport and estuarine port. if the construction area has enough water depth, there are waters at both ends for the dredger to turn head and throw mud [...]
Cutting system——transformation of the cutter
The performance of cutter Cutter is a cutting tool for cutter suction dredger to cut underwater soil. Driven by the prime mover, it rotates to cut the soil layer and causes the soil layer separated by cutting to be deformed, broken, and mixed with water to form a slurry, which [...]
Brief introduction of the disassembly process of the wheelset
At present, due to the increasing demand for dredging channels and building factories in the sea, large cutter suction dredgers are widely used in port construction and Marine development, playing a huge role. Cutter suction dredger is a kind of offshore construction equipment with a complex system and high technical [...]
Influence of flow rate and concentration on production efficiency
1.Flow rate The dredger is operated under certain working conditions, and its output flow is rated under normal conditions. In order to obtain maximum productivity, it is necessary to choose the optimal construction scheme and maximize the output flow while ensuring the normal operation of the dredge pump. Under the conditions [...]
Operation methods for different soils
Excavation of hard clay: the water content of hard clay is low, high viscosity and hardness, and is not easy to collapse and excavation broken. It is difficult to excavate with bucket wheel head cutter, it is necessary to increase power to reduce the bucket wheel head speed, swing speed, [...]
Pipeline laying method
Floating pipe laying Float pipe of a certain length shall be laid after the stern pipe of the cutter suction dredger conveying pump. The floating pipe adopts the form of a plastic pontoon-covered steel pipe, and the steel pipes are flexibly connected with 1.5m long rubber pipes. So that the [...]
