What are the advantages and disadvantages of hydraulic transmission

The advantages of hydraulic transmission
1. Hydraulic transmission can output large thrust or torque, achieving low-speed and large tonnage movements, which is an outstanding advantage that other transmission methods cannot compare to.
2. Hydraulic transmission can easily realize stepless speed regulation, with a wide range of speed regulation, and speed regulation can be achieved during system operation.
3. Under the same power conditions, hydraulic transmission devices have small volume, light weight, and compact structure. Hydraulic components can be connected through pipelines or integrated connections, which have great flexibility in layout and installation, and can form complex systems that are difficult to form with other transmission methods.
4. Hydraulic power transmission ensures that the movement of the actuator is very uniform and stable, allowing for no directional impact when the moving components change direction. Moreover, due to its fast reaction speed, it can achieve frequent switching.
5. Easy to operate, easy to adjust and control, and easy to achieve automation. Especially when used in conjunction with machinery and electricity, it is convenient to achieve complex automatic work cycles.
6. The hydraulic system facilitates overload protection and is safe and reliable to use. Due to the fact that the moving parts in each hydraulic component work in oil and can lubricate themselves, the service life of the components is long.
7. Hydraulic components are easy to achieve serialization, standardization, and generalization, making them easy to design, manufacture, maintain, and promote for use.

Disadvantages of hydraulic transmission
1. The leakage of oil and the compressibility of the liquid can affect the accuracy of the movement of the actuator, so strict transmission ratios cannot be guaranteed.
2. Sensitive to changes in oil temperature, it is not suitable to work under high or low temperature conditions.
3. The energy loss (leakage loss, overflow loss, throttling loss, friction loss, etc.) is significant, the transmission efficiency is low, and it is not suitable for long-distance transmission.
4. When the system malfunctions, it is difficult to identify the cause. In summary, the advantages of hydraulic transmission are major and prominent, and its disadvantages will gradually be overcome with the development of science and technology. The development prospects of hydraulic transmission technology are very broad.
