In the field of hydraulic technology, the reliability of hydraulic pumps is of vital importance. It is directly related to the stable operation of various hydraulic systems. From large - scale industrial equipment to sophisticated aerospace machinery, all rely on the reliable operation of hydraulic pumps. The project "Research on Short - Time Test Method for Hydraulic Pump Reliability" (supported by the National Natural Science Foundation of China) presided over by Professor Zhao Jingyi is like a guiding light, illuminating the way forward for the development of this field.

I. Research Background and Significance

As the core component of hydraulic systems, the reliability of hydraulic pumps has always been the focus of attention in the industry. Traditional reliability test methods often require a great deal of time and resources, which not only increases research and development costs but also delays the product launch cycle. In today's fast - paced industrial development, there is an urgent need for an efficient and accurate short - time test method to quickly evaluate the reliability of hydraulic pumps. Professor Zhao Jingyi's research project emerged precisely in this context, aiming to fill the domestic gap in this field, promote technological progress in hydraulic pump reliability research, and provide strong technical support for the development of China's hydraulic industry.

II. Research Contents and Innovation Points

During the research process of the project, Professor Zhao Jingyi led the team to deeply explore the short - time test method for hydraulic pump reliability. Through the analysis of the working principle, failure modes, and various influencing factors of hydraulic pumps, they established a set of scientific and reasonable test schemes.

One of the innovation points is the adoption of accelerated stress test technology. By simulating extreme conditions in actual working conditions, such as high temperature, high pressure, and high pollution, the failure process of hydraulic pumps is accelerated, enabling the acquisition of reliability data in a relatively short time. This method can not only reflect the reliability of hydraulic pumps in actual use but also significantly shorten the test time and improve test efficiency.

Another innovation is the establishment of a comprehensive reliability evaluation model. The research team considered multiple factors such as the performance degradation of the hydraulic pump, the occurrence of failures, and the influence of environmental factors, and established a mathematical model to comprehensively evaluate the reliability of the hydraulic pump. This model can not only provide accurate reliability prediction results but also help to identify the weak links in the hydraulic pump design and manufacturing process, providing a basis for improving the reliability of the product.

III. Research Results and Applications

After years of hard work, the project has achieved a series of important research results. The research team has successfully developed a set of short - time reliability test systems for hydraulic pumps based on accelerated stress. This system has the advantages of high precision, high reliability, and a high degree of automation. Through practical applications in multiple enterprises, it has been verified that this system can accurately evaluate the reliability of hydraulic pumps, providing strong support for enterprise product research and development and quality control.

At the same time, the comprehensive reliability evaluation model proposed in the project has also been widely applied. Enterprises can optimize the design schemes of hydraulic pumps according to this model, identify potential reliability problems in advance, thereby reducing the product failure rate and improving the market competitiveness of products. In addition, the research results also provide a theoretical basis for the fault diagnosis and maintenance of hydraulic pumps, helping to improve the overall operation efficiency and reliability of hydraulic systems.
