[Abstract]:According to the requirement of sea water pump in reverse osmosis seawater desalination system, a new structure of sea water pump is designed and applied to reverse osmosis seawater desalination system using tidal current energy. The use of new energy is also an important means to solve the current energy crisis, and the ocean energy as a clean, renewable, rich in resources, development prospects are very optimistic. Therefore, a new pump structure is designed to adapt to reverse osmosis seawater desalination system. Based on the above ideas, a new type of piston pump, moving shell radial piston pump, is proposed in this paper. In this paper, a new type of piston pump is designed with reference to the structure of other seawater piston pumps. Under the objective of this task, the paper mainly does the following tasks: (1) according to the analysis of the working conditions and working environment of the sea pump, the design requirements and innovation requirements of the sea pump are understood, and the similar designs at home and abroad are consulted. Conceive the structure form of sea pump. After the determination of the general structure, the feasibility and technical difficulties are analyzed. (2) on the basis of analyzing the design requirements and searching a large number of references, the structural scheme of the seawater radial piston pump is determined. After the structure of the radial seawater piston pump is determined, the curve profile of the water pump is determined, and the motion simulation of the structure is carried out by using Pro/Mechanism/MECHANICA to analyze its motion form and force. (3) after determining the structural parameters of the key parts of the sea pump, the three-dimensional modeling software PRO/E is used to model the seawater plunger pump, and the two-dimensional drawing is drawn. According to the working environment of seawater and the principle of material selection of hydraulic components, suitable materials are selected for different parts. The processing technology of sea pump parts is designed and the prototype is designed for experimental analysis. (4) analyzing the flow distribution mode applied to the pump body structure, comparing the advantages and disadvantages of the various flow distribution modes, and selecting the flow distribution mode suitable for the design of the seawater piston pump. The structure and dimension parameters of the valve are designed, and the spring parameters of the valve are designed. The performance of the valve is simulated by AMESim software. In this paper, the structure design of a new type radial plunger is completed through the above work, and the preliminary prototype is manufactured, and further experimental analysis is carried out.
