液压元件质量的好坏,是由设计、材质、制造、装配、试验、包装、使用等各个环节的优劣决定的。只重视其中某些环节,忽视某一个环节,也不会生产出高质量的产品。质量好坏是企业中各个环节的综合反映。从多年生产液压件的教训和体会中感到:影响产品的性能可靠性、外漏、寿命的因素虽 The quality of hydraulic components is good or bad, by the design, material, manufacturing, assembly, testing, packaging, use and other aspects of the merits of the decision. Only pay attention to some of these links, ignore a certain link, it will not produce high-quality products. Good or bad quality is a comprehensive reflection of all aspects of the enterprise. From years of experience in the production of hydraulic parts and experience: the impact of product performance reliability, leakage, life factors
