系列高效海水淡化高压泵的研制

Development of a series high efficiency seawater desalination high pressure pump

为了研制国产系列高效反渗透海水淡化高压泵产品并实现产业化,应用国家科技支撑课题最新技术,结合当前世界海水淡化高压泵制造技术的发展新趋势,并根据实际使用中的性能要求,通过从总体结构、轴向力平衡装置、轴承润滑方式、耐磨材料等入手,进行了大量的研制、试制及试验工作.并针对目前现有产品存在的问题和品种较单一的状况,研制开发了满足日产5 000,10 000,15 000 t淡水的海水淡化装置的3种规格高压泵产品,经生产、试验及用户使用结果表明,该系列高效高压泵产品的性能指标已达到目前国际上同类产品的技术水平.

In order to develop a series products of high efficiency reverse osmosis seawater desalination high pressure pump and realize its industrialization, a lot of work, such as design of both overall structure and axial thrust balance device, selection of both bearing lubrication and wear-resistant materials and so on, was done in the pump development, trial production and testing based on latest techniques developed in national scientific and technological support projects by combining the new development trend of manufacturing technology in desalination high-pressure pumps in the world and by considering actual requirements of pump end-users on the pump performance. As a result, these products of high pressure pumps are developed for seawater desalination systems with 5 000, 10 000 and 15 000 tonnes daily output, respectively. The problems in existing products of the high pressure pump and the situation of a less varied variety in the products are turned over. Based on production, experiment and user application, it is shown that the performance of these series of pro-ducts has reached the same level of the similar products in the world.
