Hydraulic transmission mainly uses the pressure energy of liquid to transfer energy. Because hydraulic transmission has many outstanding advantages, it is also widely used in machinery manufacturing, transportation, military equipment, mining and metallurgy, light industry, agricultural machinery, and other aspects. There are also various engineering and technical fields such as aerospace, marine development, nuclear energy engineering, and earthquake prediction. The vast majority of people in life can touch and understand tools and equipment such as hydraulic vehicle positioning jacks and hydraulic power units.
Compared with mechanical transmission and electric transmission, hydraulic transmission has the following main advantages:
1. Under the same conditions, the hydraulic actuator used is small in size, simple in structure, and easy to disassemble and unload.
2. According to different working conditions, the hydraulic components can be assembled at will to meet the working requirements.
3. The use of hydraulic transmission can make the workpiece and components work stably. Can perform fast forward, braking, steering, and other operations by itself
4. There is no complicated operation process when in use, and the speed range is wide.
5. Mineral oil is the first choice for general working media, which can prolong the service life of hydraulic systems or components.
6. It is easy to realize linear motion.
7. It can be automated, and when there is an overload phenomenon, it can also protect the hydraulic system components.
8. Standardized, serialized, and generalized components greatly facilitate the use of design and industrial manufacturing.
