Barnacles and other marine organisms attached to the surface of the hull will increase the roughness of the hull. As the number of barnacles increases, the additional weight and resistance of the hull will cause the speed to decrease. This leads to increased water resistance during navigation. This requires more energy for the ship to maintain the same speed, thereby increasing fuel consumption. Marine organisms such as barnacles not only increase the burden on the hull, but may also accelerate the corrosion of the hull material, especially the metal hull. Regular cleaning can effectively prevent corrosion and extend the service life of the hull. Therefore, regular cleaning of marine organisms and barnacles is essential.
High-pressure cavitation technology (also known as cavitation or cavitation effect) has unique advantages in the treatment of marine organisms and barnacles on the surface of the hull. By utilizing the cavitation effect generated by high-pressure water flow, marine organisms such as barnacles attached to the hull can be removed efficiently and environmentally friendly. The following are the specific applications and advantages of this technology:
1. Technical principle High-pressure cavitation technology is to pressurize water to a very high pressure (usually more than 100bar) through a high-pressure water pump, and then spray it out at a very high speed through a special nozzle. During the jetting process, bubbles in the water flow will form and burst rapidly, generating strong shock waves and local high temperature and high pressure environment. These shock waves can effectively destroy the shells and adhesion structures of marine organisms such as barnacles, thereby stripping them from the surface of the hull.
2. Main advantages Efficient decontamination
• Strong impact: The shock waves generated by the cavitation effect can penetrate into the gaps and unevenness on the surface of the hull, and completely remove barnacles and other marine organisms.
• Fast operation: Compared with traditional mechanical scraping methods, high-pressure cavitation technology can complete large-scale cleaning work in a shorter time and improve work efficiency.
Environmentally friendly and non-destructive
• No chemical agents: No chemical agents are used in the whole process, which is environmentally friendly and will not pollute seawater.
• Protect the hull: Since the cavitation effect mainly removes barnacles through the energy generated by the rupture of bubbles, rather than directly contacting the surface of the hull, it will not cause damage to the hull and extend the life of the hull.
Cost savings
• Reduce fuel consumption: The attachment of marine organisms such as barnacles will increase the resistance of the hull, resulting in increased fuel consumption when the ship is sailing. Regular use of high-pressure cavitation technology to clean the hull can significantly reduce fuel consumption.
• Reduce maintenance frequency: The efficient cleaning effect means that the surface of the hull can be kept clean for a longer period of time, reducing the need for frequent maintenance.
3. Application scenarios Commercial shipping
• Cargo ships and tankers: Large commercial ships often face the problem of attachment of marine organisms such as barnacles. High-pressure cavitation technology can effectively solve this problem and ensure the navigation efficiency and safety of the ship.
• Cruise ships: The appearance and navigation performance of cruise ships are crucial to the passenger experience. High-pressure cavitation technology can keep the hull clean and beautiful.
Military ships
• Naval ships: Military ships need to maintain optimal navigation performance and concealment. The attachment of marine organisms such as barnacles will affect their speed and stealth capabilities. High-pressure cavitation technology can ensure that the ship is always in the best condition.
Yachts and private boats
• Leisure yachts: The owners of private yachts want to maintain the beauty and performance of the hull. High-pressure cavitation technology provides a convenient and efficient solution.
• Fishing boats: Fishermen rely on the efficient operation of their boats. High-pressure cavitation technology can help them save fuel and extend the service life of their boats.
4. Operation precautions
•Safety protection: Operators should wear appropriate protective equipment, such as goggles, gloves, etc. to ensure safety.
•Equipment inspection: Before use, be sure to check whether the high-pressure water pump, nozzle and other key components are intact to avoid accidents caused by equipment failure.
