Due to the wide application of high-tech achievements in hydraulic technology, such as automatic control technology, computer technology, microelectronics technology, friction and wear technology, reliability technology, new technology and new materials, the traditional technology has made new development, and the quality and level of hydraulic systems and components have also been improved to a certain extent. However, it is impossible for the hydraulic technology facing 2 1 century to make an amazing technological breakthrough. We should mainly rely on the improvement and expansion of the existing technology and constantly expand its application fields to meet the future requirements.

① Reduce internal pressure loss of components and systems to reduce power loss. The main performance is to improve the pressure loss of the internal flow channel of the component, and the use of integrated circuits and casting flow channels can reduce the pipeline loss and oil leakage loss.

(2) Reduce or eliminate the throttling loss of the system, minimize the overflow of unsafe needs, and avoid using the throttling system to adjust the flow and pressure.

③ Adopting static pressure technology and new sealing materials to reduce friction loss.

④ Develop miniaturization, light weight and compounding, and extensively develop 3-way and 4-way solenoid valves and low-power solenoid valves.

⑤ In order to improve the performance of hydraulic system, load sensing system, secondary regulation system and accumulator circuit are adopted.

⑥ In order to maintain the hydraulic system in time and prevent pollution from affecting the life and reliability of the system, it is necessary to develop new pollution detection methods, measure pollution online and adjust it in time, and it is not allowed to lag behind to avoid losses caused by untimely treatment.
