Design And Research On The Central Water Cooling System In Land-based Engine Room

In this paper, as an opportunity of the establishment of Dalian Maritime University onshore engine room, through the systematic introduction and explain the central cooling water system components and design process, also hope that by the secondary development of software to simplify the design cycle, in order to achieve the central cooling water system more systematic research.The actual process carried out in the paper, mainly through the method of inquiry on the design process, especially through compare with the central cooling water of the ship design, to carry out the water cooling system of land-based engine room design. Land-based engine room as the simulator can simulate ship actual function and applied in the teaching fields, it has many similarities to the ship, but from microscopic point of view, the particularity of the land-based must also be noticed. This article focuses on the perspective of system equipment, added the water tower and hydraulic dynamometer to the design process, consider the system of cooling capacity, and make selection. In the actual design, through the use of the AutoCAD design software by secondary development, thermal equilibrium diagram, the system diagram design process can be simplified.In this paper, through the central cooling water system of Dalian Maritime University land-based engine room design to carry out the system research design. In the central cooling water system of land-based engine room design, switch series of the calculation of the overall cooling, equipment selection and thermal equilibrium diagram, the system diagram design as the main process of the design. After this, through VBA technology to start the secondary development of the AutoCAD, simplified the design process.Through the research of design process and further found that the land-based engine room design inevitable vibration problem. Maritime education in further perspective, the establishment of land-based engine room is an inevitable trend, and through this paper, the engine room design is to rise up some of the more comprehensive establishment of the proposed design method, while, also hope the specificity mentioned in paper can make meaningful in the design of land-based engine room.
