Benthic lander buoyancy
| Density : | 0.54g/cm³ |
| Size : | 1300*1300*800mm |
| Depth : | 4500m |
| Application Areas : | Benthic lander |
Benthic lander buoyancy is a key component in deep-sea exploration equipment, and its design is directly related to the stability, safety and operational efficiency of the lander. With the continuous development of deep-sea exploration technology, the materials and structures of lander buoyancy are also constantly being innovated to adapt to more complex and harsh deep-sea environments.
The main function of the benthic lander buoyancy is to provide sufficient buoyancy to ensure that the lander can hover stably or sink slowly in the deep-sea environment, while withstanding huge water pressure. The performance of the lander buoyancy directly affects the operating depth, load capacity and recovery success rate of the lander. For instance, in deep-sea scientific expeditions, the lander needs to stay for a long time and collect samples. The buoyancy stability of the lander buoyancy determines whether the equipment can successfully complete the predetermined tasks.
In addition, the lander buoyancy also needs to have the characteristics of corrosion resistance, high pressure resistance and lightweight. The high pressure, low temperature, high salinity and possible chemical and biological corrosion in the deep-sea environment pose extremely high requirements for the performance of buoyancy materials. If the buoyancy fails, it may result in the lander being unable to be retrieved, causing huge economic losses and data loss.
The material selection of the benthic lander buoyancy is one of the core issues in the design. The commonly used buoyancy materials at present include high-strength composite materials such as microsphere-type solid buoyancy materials.
