摘要
中国船舶及海洋工程设计研究院基于其在喷水推进水力性能试验方面的研究工作,形成了国际标准(ISO 4679):《船舶与海洋技术喷水推进水力性能试验》,文中对该国际标准的主要内容进行介绍。ISO 4679规定了喷水推进水力性能试验的术语、验收准则、试验方法和试验报告等内容,并提供了试验报告格式和试验装置的参考案例。喷水推进水力性能试验包括水力性能试验和汽蚀性能试验,针对科学研究和出厂验收2种不同用途,可被划分为A级和B级2种精度等级。A级为精密级,适用于标称直径在300 mm及以下的水力模型或精度要求高的实型试验;B级为工程级,适用于中小型实型产品的批量试验验收、中间试验模型泵的检验。对于不同的精度等级,标准中均规定了相应的验收准则。ISO 4679的制定,在喷水推进水力性能试验领域为相关各方建立了统一的对话平台,降低了技术交流壁垒,有利于推动喷水推进试验技术的进一步发展。
Marine Design and Research Institute of China(MARIC)established the international standard(ISO 4679):Ships and marine technology—Hydraulic performance tests for waterjet propulsion system based on the research on hydraulic performance tests for waterjet propulsion system.The current study focuses on the main contents of the ISO 4679.The ISO 4679 specified the terms and definitions,the acceptance criteria,the test method and the test report of hydraulic performance tests for waterjet propulsion system,and provided the examples of test report template and test devices.The hydraulic performance tests for waterjet propulsion system include hydraulic performance tests and cavitation tests(optional),divided into Class A and Class B for the two different purposes of scientific research and acceptance test,respectively.The Class A is of precision grade for hydraulic model tests with a nominal diameter of 300mm or below,or high precision prototype tests.And the Class B is of engineering level for batch acceptance tests of small and middle-sized models or intermediate tests of pump models.The standard ISO 4679 specifies corresponding acceptance criteria for the two levels.The formulation of ISO 4679 builds a unified communicating platform for relevant parties in the hydraulic performance tests for the waterjet propulsion system,weakening the barriers to the technical exchange and advancing the development of the test technology for the waterjet propulsion system.
