In the challenging field of dredging engineering, practitioners often face a series of difficult problems. With the continuous development of modern dredging operations, higher requirements are placed on the flexibility and adaptability of pipelines. The traditional pipeline design has gradually been replaced by flexible string design. Flexible hoses, with their unique advantages, can better adapt to complex water conditions and changing working environments, making them an ideal choice for current dredging operations.
The main advantages of flexible hose:
● Flexible hoses can be easily bent and twisted to adapt to complex terrain and working environments. During dredging operations, they can be flexibly adjusted as the hull or equipment moves, reducing stress concentration problems caused by the inability of rigid hoses to bend.
● Flexible hoses can absorb external shocks and vibrations, reduce mechanical damage to the string system, and during dredging operations, when facing waves, water flow shocks or equipment vibrations, flexible hoses can maintain stable operation and reduce the risk of rupture.
● Adapt to a variety of complex working conditions, such as high pressure, high flow rate, corrosive media or extreme temperature environment.
● Compared with rigid hoses, flexible hoses are lighter and easier to transport, install and disassemble. In dredging operations, the lightweight design reduces equipment load and improves operating efficiency.
During the use of flexible strings, whether it is daily maintenance or replacement of damaged hoses, there are some key points that need to be strictly controlled. When replacing a damaged hose, the first principle is to maintain consistent diameter. The diameter of the original hose directly determines the flow rate and flow rate of the fluid. Only when the replacement hose has the same diameter as the original hose can the stability and efficiency of the system be ensured not to be affected. Once the diameter of the hose changes, whether it becomes larger or smaller, it may cause a series of problems such as uneven flow and unstable flow rate.
The change of string length will also have a significant impact on the operation. The increase of string length will increase fluid resistance and pressure loss, thereby reducing the transportation efficiency; shortening the length of the string can reduce pressure loss and improve transportation efficiency. Therefore, when changing the length of the hose, multiple factors such as fluid transportation distance, flow rate and pressure must be fully considered and reasonable planning must be carried out to ensure stable operation of the string.
