Abstract
Hydraulic transmission system is the core power transmission mode in modern industrial and mechanical equipment, and its energy efficiency analysis and optimization are of great significance for improving equipment performance, reducing energy consumption and enhancing market competitiveness. In this paper, the energy efficiency characteristics, influencing factors and optimization strategies of hydraulic transmission system are discussed in depth, aiming at providing scientific basis and technical support for the design, operation and maintenance of hydraulic transmission system. This paper summarizes the working principle and basic composition of hydraulic transmission system, including hydraulic pump, hydraulic cylinder, hydraulic valve and other key components, as well as their interaction and energy conversion process. Then, the energy efficiency of the hydraulic transmission system is analyzed comprehensively, and it is pointed out that its energy efficiency is affected by many factors, such as the selection and matching of hydraulic components, the layout and design of the system, the performance and state of the working medium, and the precision and response speed of the control system. In terms of energy efficiency optimization, this paper puts forward a number of specific strategies. First, through the reasonable selection of hydraulic components, such as the use of high-efficiency pumps, optimize valve design, etc., to reduce the loss of energy in the conversion and transmission process. The second is to optimize the system layout and pipeline design, reduce pipeline resistance, reduce pressure loss, and improve the overall efficiency of the system. The third is to choose a working medium with excellent performance, such as high viscosity index hydraulic oil, to improve the lubrication performance and thermal stability of the system, and further improve energy efficiency. The fourth is to introduce advanced control technology, such as frequency conversion speed regulation, intelligent control, etc., to achieve accurate adjustment and dynamic optimization of system parameters, and improve the response speed and stability of the system. This paper also emphasizes the importance of daily maintenance of hydraulic transmission system. By regularly checking the wear of hydraulic components, maintaining the cleanliness and good lubrication performance of hydraulic oil, and timely detection and treatment of leakage problems, you can effectively extend the service life of the hydraulic transmission system, reduce the failure rate, and further improve the energy efficiency level. The energy efficiency analysis and optimization of hydraulic transmission system is a complex and systematic project. Through the comprehensive use of a variety of technical means and management measures, the energy efficiency level of the hydraulic transmission system can be significantly improved, providing a strong guarantee for the efficient operation and sustainable development of industrial production.
