What are the new features of modern hydraulic transmission technology?

Hydraulic transmission technology, as an important industrial technology, has always been closely related to previous industrial revolutions in its development process.

However, under the new development background, the integration of hydraulic transmission technology with industry and manufacturing has undergone significant changes compared to before. Modern hydraulic transmission has developed into a comprehensive technology that is interrelated and intersecting with various disciplines such as mechanics, materials, electronics, sensing, detection, computer science, control, and signal technology. In the new development environment, especially the deep integration of advanced manufacturing technology and information technology, hydraulic transmission technology is constantly being promoted to present more new features.

"Intelligence" refers to intelligence. In recent years, the concept of intelligent hydraulic components has emerged, but intelligent hydraulic is still in its early stages. The intelligentization of motor transmission also provides more development opportunities for the intelligentization of hydraulic transmission technology.

"Micro" refers to miniaturization. On the one hand, adopting modern design and manufacturing methods can provide more compact transmission technology solutions for the industrial field. On the other hand, the application object can be extended from traditional large-scale equipment to modern low-power, high-energy density equipment.

"Clever" means agile. Modern hydraulic transmission technology has great potential in the field of artificial intelligence. Compared to traditional applications, which are often associated with bulky equipment, hydraulic transmission technology in these emerging devices performs more flexibly, such as biomimetic robots. In addition, the lightweight application of hydraulic transmission devices also provides new ideas for modern hydraulic transmission technology to serve intelligent equipment.

"Precision" means precision. Traditional hydraulic transmission technology is mainly applied in scenarios with low motion accuracy requirements, while for precision transmission such as feed motion of precision machine tools, motor drive is generally chosen. Due to the integration of advanced control methods in modern hydraulic transmission technology, the linear motion positioning accuracy and rotary motion positioning accuracy of hydraulic driven loads are comparable to those of motor drives. Moreover, modern hydraulic transmission technology can not only serve harsh working conditions, but also expand new application fields for clean environments, in line with contemporary development needs.

"Low" means low energy consumption. The trend of energy conservation and consumption reduction in the field of hydraulic transmission is becoming increasingly evident, and low energy efficiency is precisely the fatal weakness of hydraulic transmission. If we want to compete with other transmission technologies, the next step of modern hydraulic transmission technology must achieve hard indicators of energy conservation and environmental protection.

In recent years, with the rise of new intelligent materials, the modernization level of hydraulic transmission technology has also been accelerated. For example, piezoelectric materials have fast response, high output force, and low power consumption, and can be used to manufacture various hydraulic valve actuators. Magnetorheological fluid is also used in non magnetorheological valves. By controlling the current of the valve excitation coil, the pressure difference at both ends of the valve port can be freely adjusted.

In addition, the integration of hydraulic transmission and advanced manufacturing technologies is constantly deepening, such as additive manufacturing, commonly known as 3D printing technology. Hydraulic components usually have complex channels for oil supply and fluid flow inside, making traditional manufacturing techniques difficult to manufacture. However, 3D printing technology provides an ideal solution, which is highly likely to have a transformative impact on traditional hydraulic component manufacturing technology and production models in the future.

Modern technology is constantly updating and developing. If hydraulic transmission technology wants to avoid being eliminated, it must keep up with new technological trends, fully leverage its own advantages, leverage its strengths and avoid weaknesses, and continuously arm itself with modern information technology, so as to continue to shine and shine in modern industry and manufacturing.
