Industry: Domestic Marine Pumps Should Accelerate Technological Reform

In marine machinery and equipment, the marine pump is a kind of important ship supporting product with large quantity and many varieties. It is widely used in ship power system, fire fighting system, cooling system, ballast system, stripping system, life service security and other Dedicated systems are also fitted in some auxiliary devices. In recent years, the trend of large-scale domestic vessels, diversified ship types, and ship-wide automation has become increasingly evident. China urgently needs to replace traditional products with a new generation of marine pumps. On July 9th, at the “Academic Report on New Technology for Ship Auxiliary Machinery” organized by the Academic Committee of Shipbuilding Auxiliaries of the Shanghai Shipbuilding Engineering Society, experts recommended that efforts should be made to grasp the trend of marine pump technology, enhance technological innovation capabilities, and improve marine use. Pump design, manufacturing level.

The meeting emphasized that marine pump manufacturers should open up a series of high-parametric marine pump design innovations such as high-speed, high-temperature, high-pressure, and high-power density. With the continuous development of domestically-produced ships, the main power of ships has been continuously upgraded, and the parameters such as displacement, head, and power of functional pump products in ship power systems have been greatly improved, and even a qualitative leap has emerged. At the same time, Weight, installation, etc. have different restrictions and constraints on the product. These require that the marine pump design accelerates the pace of innovation and develops to ultra-high speed, high temperature, high pressure, and high power density as soon as possible.

In recent years, although the design level of China's domestic marine pump has been greatly improved, most units still use semi-theory and semi-empirical design methods, and it is difficult to fully meet the user's proposed performance parameters, weight profile, reliability, environmental conditions, etc. Multi-target design requirements. The development of informatization technology provides a leveling for the design of complex marine pumps. For this purpose, experts should use the advantages of the platform and combine the CAD-CAF-CAM technology to form a multi-objective design method for marine pumps and improve marine pumps. With regard to the level of design technology, relevant enterprises and institutions should grasp the multi-objective design technology of marine pump based on digital design as soon as possible.
