减速机在潜水推流设备中的应用设计

普通减速机在污水处理行业潜水推流设备中使用情况不理想,寿命短,故障率高,水下工况适应性差。为改变应用现状、提高潜水推流器力学性能、运行可靠性和产品竞争能力,对减速机进行专配和专用化潜水式应用改进设计。新型潜水式减速机在密封、强度及防腐等方面有很多重要注意事项和技术特点,故对此进行介绍和描述,并重点突出结构和密封技术优势,以及与整机配套的协调性、可靠性和适应性。

Underwater Recording and 3D Modeling during a Dive Training Course： A Case Study at Panormos, Skopelos, Greece

In the field of underwater survey, there is a variety of methods which differ from each other in terms of the operating environment and the purpose that each method is used. Hence, some of the state-of-the-art methods, that have many applications in the various scientific fields nowadays, are introduced in this paper. Additionally, the application of the procedures for an underwater survey in shallow depths is analyzed in accordance with the training standards of the PADI Underwater Survey Diver distinctive specialty. The main goal is to demonstrate not only the theoretical background of underwater surveys but also their operational issues, in order to facilitate the development of knowledge and skills during a training course. Finally, a case study for the recording and 3D modeling of the seabeds＇ morphology in shallow water is presented as it has been organized and accomplished by the participants of such a training course. By this way, it is expected that the reader will understand explicitly the application of the procedures prior, during and after the dive for an underwater survey in shallow depths.
